research hypothesis is grounded in the conviction that three complementary approaches to current courses of action can enhance this knowledge and clear
the way for strategies that will be more effective in reaching (and then caring for) the people on the outskirts of health policies and the healthcare
Our purpose is to broaden the
model of health determinants to include social characteristics other than the standard ones (employment, resources and education) and take account of
certain psychosocial and behavioural characteristics (specifically pertaining to health representations as well as to self-esteem and adaptability) and
incorporate the level of individuals’ social integration (including the density of their social network, the magnitude of their social support and breaks
in their life-history), and do so by studying a representative cohort of Ile-de-France residents and by conducting micro-local studies in city
neighbourhoods (particularly in Paris). We aim also to use methods of contextual and spatial analysis to take account, simultaneously, of individual
characteristics and contextual characteristics (pertaining to the individual’s socioeconomic environment, such as the city neighbourhood) in statistical
models attempting to explain the individually observed health differences (perceived health, health attitudes and behaviours, health recourses).

Nineteenth Century Hygienist Movement, numerous studies have reported the existence of a link between individuals’ health and their socioeconomic
situation. Despite ongoing biomedical and technological progress over the past 50 years and despite the broader coverage of sickness protection, social
inequalities in health have endured or even worsened comparatively throughout the social groups since the nineties, in all the developed countries, and
specifically in our country. France has long lagged behind in the attention it has paid to health inequalities, even though, as early as the seventies, Insee studies clearly established the considerable differences in mortality according to social categories. After
associations and health professionals mobilised against the phenomena of observable exclusion from care that affected the indigent, in the eighties,
research in this field enjoyed renewed development, underscored by the publication of the Hcsp reports and several works by INSERM.,
the inequalities is not enough to reduce them, the challenge is to explain them and move toward an understanding of the underlying mechanisms. However,
whether focussing on mortality, morbidity, health behaviours, or people’s consumption of healthcare, the available social indicators (professional and
social category, income bracket, level of education, public action beneficiaries such as the unemployed or RMI recipients) often only provide an
approximate description of people’s socioeconomic position. The indicators provide an even poorer grasp of their living conditions and neo-material
conditions (related to lifestyle in post-industrial societies: diet, leisure, ownership of certain consumer goods access to means of communication, and so
on), and no grasp at all of their psychosocial characteristics.
advantage of further in-depth studies is to renew the study of inequalities in health based on a better understanding of the interactions between social
situations (in the broad meaning of the term) and health. The point is to measure the sanitary impacts of different forms of vulnerability during the
entire course of the social continuum. We hypothesise that social situations detrimental to health do not only concern people experiencing precariousness.
Indeed a growing number of recognised authors in social epidemiology underscore the relevance of studying new individual determinants. A growing number of
public health research papers, overlapping the fields of social epidemiology and health sociology, are tackling the issue of the social determinants of
health determinants. The research is based on conceptual models still under discussion, as are the chains of causality, which are obviously never direct,
that link the reported psychosocial or socioeconomic characteristic of an individual and/or a group of individuals with a reported health differential
(currently arguments of proof, and specifically experimental or biological arguments, have only been exceptionally demonstrated).
following determinants should be mentioned: individuals’ representations of health, the care paid to their health and the ranking of health needs compared
to other basic (or deemed basic) needs of the person, some psychosocial characteristics (such as self-esteem, adaptability, the aptitude to project
oneself into the future, and so on), the internalisation of medical norms, and earlier or family experiences of disease and the recourse to
care. Research on health related behaviours first got underway years ago (specifically research on health belief models). Since the fifties, the research
has accumulated results demonstrating a close relation between health beliefs and recourse to care, therapeutic compliance, the use of prevention
programmes, and the alteration of detrimental health behaviours (addictions, sexual behaviours, and so on). Research on family health behaviours (or the
‘family production’) should also be mentioned. As for the conditions of social integration, for the past twenty years numerous publications (also mainly
Anglo-Saxon) have evidenced an association between a low level of social integration and increased frequencies of high-risk behaviours (tobacco addiction,
alcoholism, eating disorders, lack of exercise, and so on). Other research, for instance, has observed strong associations between the size of an
individual’s social network and the incidence and lethality of cardiovascular diseases. Some authors have proposed theoretical models of health social
determinants that combine psychosocial characteristics as well as conditions of social integration, social support, and social capital. Research in
life-course epidemiology clears the way for promising outlooks for characterising the medium and long-term impact on health of personal breaks and
negative life events experienced during childhood or adulthood., Although the hypotheses were actually formulated some time ago (from French
sociological research, such as Durkheim’s work), a large share of their statistical demonstration still has to be done in France. Indeed “ignoring social determinants of social disparities in health precludes adequate explanations for actual and changing
population burdens of disease and death, thereby hampering efforts for prevention.”
preceding social determinants can be found - undoubtedly in a particularly acute manner - in France’s immigrant populations (among others, but not only,
because racial discriminations structure certain social inequalities). Some studies show that immigrant populations experience worse living conditions
more often than the French do (specifically in terms of resources, housing and work), conditions that are potentially detrimental to health. However,
their morbidity and recourse to care are little studied in France (unlike other countries). The description of health disparities according to
nationality, or to membership (or non membership) in an immigration group is still extremely sketchy in our country and epidemiological research on the
topic is scarcer still. Furthermore, when measuring and understanding the role of ‘migratory descent’ and it contribution to reported social inequalities
in health in France, the lack of available representative data on the population (including exclusively for research and within the framework provided for
by law) is virtually absolute, to our knowledge.
in social epidemiology have conventionally focussed on health determinants measured at the individual level, following a long tradition of epidemiology
that, thanks to the systematic collection of individual information, was forged in opposition to the scientifically dangerous and regularly criticised use
of aggregate data and ecological analyses. More recently, a concern to ‘replace the individual in his or her context’ has emerged in the field, both
because, as we have seen, results of the impacts of individuals’ social integration on their health have been amassed, and because, generally speaking,
the reductionist outlook (handed down from the exact sciences) is, in turn, widely criticised in social epidemiology. Actually, the existence of context
impacts on individuals’ health and their access to care is increasingly recognised in public health. The development of urban health research in the
Anglo-Saxon countries (and specifically research on the impacts of the built environment) or the research on people living in underprivileged
neighbourhoods should be mentioned, for instance. The flourishing literature on ‘contextual epidemiology’ deals with measuring jointly the effects of
individual and contextual characteristics on health, using the appropriate statistical methods (specifically multi-level models). Numerous studies take
account of the socioeconomic level of the neighbourhood. North European and North American research have shown that, aside from the effects linked to the
individual’s socioeconomic level, the fact of residing in an underprivileged neighbourhood is associated with different health problems, such as low birth
weight, some detrimental health behaviours, overweight, cardiovascular diseases, and so on. However, the impacts of the residential context do no only
refer to socioeconomic factors: social interaction characteristics (collective efficiency, and social capital, among others) or shared community standards
(specifically in terms of health) are also studied in North America.
same time, observably, social inequalities in health are not automatically reduced by the quantitative and qualitative increase of the supply of curative
care, as can be seen by the fact that inequalities endure despite the growing share of public healthcare
spending. Also, the goal of equality pursued by European healthcare systems has not been fully reached,, including in countries where systematic health insurance (as in France with the
Universal Health Coverage) theoretically ensures fewer financial hurdles to said care. Therefore, the issue of access to care cannot be reduced either to
individuals’ financial and material resources or to the availability of supply. The behaviours of recourse to care, the
modes of attendance and use of the healthcare system also depend on the above-mentioned factors.
inequalities and the inequalities in the recourse to care are not so much linked by a direct causal relation as by partly common determinants, tracing a similar social gradient that should to be studied. For access to care and medical consumption, access channels and patient orientation and care are not the same for all,
either. They may differ, or even reveal genuine discriminations, depending on the migratory origins of the people, their social situation, their sickness
coverage or some of their practices or life habits, for instance. The ‘social distance’ toward care facilities, or the image that people have of the
facilities, also induces symbolic deterrents that dissuade people from going to some facilities. The dissuasion works amongst the poorest as well as among
people at the top of the social ladder, who little attend maternal and child welfare centres. Recourse to care, as a relation to a central institution of
our society (medicine and its different facilities), comprises a vast set of factors encompassing standards, representations, identity and relational
processes, and the relation the society as a whole., This is probably even more flagrant as the borders between the medical and social worlds
and between health and the normative requirement to perform are blurred in our society.
observable facts have prompted us to formulate four hypotheses for our research project:
The population cannot be divided into the ‘included’ and the ‘excluded’.
These are two type-ideals that are the milestones of a continuum that comprises each person’s health an social situation (and health needs);
The determinants of health and the recourse to care describe a social
gradient that cannot be exactly superposed on conventionally described socio-professional and economic gradients. On the contrary, they must take account
of three innovative approaches: the study of social ties, the study of contextual characteristics, and the study of both within a life-course outlook, as
much as possible;
The determinants may combine to impact negatively on health and are not
sufficiently studied in the general population or recognised by health professionals and public policies;
Extant social inequalities in the access and recourse to
(curative, preventive, and sociosanitary) care in France are probably at the root of a substantial share of reported health inequalities and/or sustain
and emphasize them.
research project is built on three tracks so that we can address the different determinants of health and the recourse to care from complementary
outlooks: (1) The social and contextual determinants of the recourses to care; (2) The psychosocial and geographic determinants of health; (3) and a new
topic that we plan to develop: Health, precariousness and migration.
Track 1. Social and Contextual Determinants of the Recourse to Care
1. Social inequalities in, and rationales for the
recourse to care (P. Chauvin, I. Parizot)
Since 2002, we have been conducting several surveys of representative samples
of urban populations. Aside from survey results per se, the investigations have served as preliminary surveys for the design of the SIRS cohort rolled out
in 2005 (see infra). For instance, we have shown that foregone care for financial reasons was statistically associated with (after adjustment for
different socioeconomic and health variables) serious events experienced in childhood and adulthood, the extent of patient’s acceptance of the disease,
certain psychological characteristics such as self-esteem, and the priority given to health. The level of priority is extremely variable depending on the
individual’s age, type of job and nationality, but also depending on their familial integration. Furthermore, we have observed a significant correlation
between the lack of recourse to care and the weakness of the social network.
For her post doctorate at INSERM, I. Parizot working closely with ERIS analysed
the issue of social identities for individuals in precarious situations in their relation to free clinics. She then conducted qualitative sociological
research using non-directive interviews of the population in different Paris neighbourhoods. The comprehensive analysis underscores how much therapeutic
approaches heavily depend on social processes, sometimes conflicting with the logic of searching for biomedical efficiency. Also, the decision to resort
to care and the choice of which professional to consult appear to be very dependent on the way therapeutic care is integrated into the patient’s social
and family life, symbolically and in terms of its (actual or supposed) material repercussions. The intensity of social ties – and chiefly the meaning they
have for individuals – largely influence that way they experience and interpret their difficulties, define their expectations of the health system, decide
whether or not to resort to the care system, and their modes of recourse. Her research helped pinpoint some aspects that had to be addressed in the SIRS
cohort, specifically social roles and the size of the social network in the different spheres of socialisation (family, professional, friends and
Our past research has also attempted to understand and assess to what extent
(aside from their individual characteristics) people’s environment explains their modes of recourse to care and/or certain morbid disorders. The
‘contextual epidemiology’ research conducted mainly by B. Chaix for his doctorate took two approaches. One, certain structural characteristics of the
environment are taken into account at different levels (household, neighbourhood, municipality, employment zone, and region), by using multi-level mixed
models. Two, their spatial scope is also analysed in a more innovative approach, thanks to the use of geographic information systems and individual
geocoding. We focussed on studying the impact of the family context, the economic characteristics, and the medical density on the recourse to different
kinds of care (first recourse, specialist, and prevention), in a first set of second-tier data analyses: SPS survey (Irdes), permanent sample of the health insured (Cnam), Health
The SIRS cohort study
Since 2005, one of the team’s central projects has been the design of the SIRS
(santé, inégalités et ruptures sociales dans l’agglomération parisienne, health, inequalities and social breaks in the greater Paris area) cohort
that is a general survey (in the field of social epidemiology). During the last quarter in 2005, 3,000 household-individuals were included in the
name-based cohort and questioned during face-to-face interviews the first time. The 3,000 individuals represent a random sample (3-stage randomised
sampling: IRIS, household, household adult), representative of the French-speaking adult population living in Paris and in the near suburbs (départements:
92, 93, and 94), where households living in Zone Urbaine Sensible (ZUS, deprived urban areas) and underprivileged neighbourhoods are
The SIRS cohort is a French first in the field of social epidemiology.
To our knowledge, it is the first representative cohort of the general population. The cohort was put together on an ad hoc basis for the study of
the social determinants of health, over-representing underprivileged neighbourhoods, geocoding respondents, and collecting a large number of social and sanitary characteristics
during face-to-face interviews. It includes characteristics that have never been addressed in the general population (integration and social identity,
social capital, health representations and beliefs, reasons for non-recourse to care, and so on).
The longitudinal scope
will help make future progress in interpretations, in terms of the causality of the associations highlighted transversally, and address new hypotheses
concerning causal mechanisms during later surveys. The regional scope makes it possible to study the entire (Ile-de-France)
social continuum and certain geographical and contextual aspects of health and recourse to care. The cohort designed in close
collaboration with the research team on social inequalities (ERIS) headed by S. Paugam at the Maurice Halbwachs Centre (Cnrs-Ehess-Ens) and with Ined. The third in-depth wave scheduled for
winter 2008/2009 will include an over-sampling of Paris, and be conducted in close collaboration with the Atelier parisien de santé publique (Apsp, Paris workshop for public health) with which we have decided to pool our human and financial resources to
monitor the cohort.
We intend to
continue analysing the social determinants of the recourse to care based on the SIRS cohort data, by exploring the three following aspects more thoroughly
The analysis of social ties (specifically as sources of material, emotional,
informative, symbolic and identity support), focussing on a better qualification of their intensities and combined impacts;
The living environment (supply of primary care and social services) but we also
will be looking at the residential and employment areas as one of the aspects of individuals’ social integration where certain rationales of the recourse
to care are devised; as places of social life where the relation to self and to others is built, where standards and values are internalised, and a
relation with the future is forged;
The representations and attitudes toward health and medicine. We hypothesise
that they mediate the relation between social situation and recourse to care, as do certain psychosocial characteristics such as self-esteem, locus of
control, the ability to cope, or the feeling of personal efficiency. All these characteristics are likely to impact an individual’s ability to harness his
or her social resources - in this case, cope with illness, manage or compensate for the negative consequences of potential recourse and, last, resort to
care. The qualitative sociological analyses that will be conducted by I. Parizot in the team and at ERIS, and for
Equalsoc, the European network of excellence she belongs to, will usefully complement the statistical analyses.
2. The social determinants of
the recourse to screening (V. Massari, P. Chauvin)
In France, the Aids control policy is based on information, prevention,
non-stigmatisation, and voluntary screening. Thus, the study of the circumstances surrounding the request for an HIV screening test in a non-selected
population is vital. In her past research, V. Massari studied these as well as the circumstances surrounding HIV screening tests, in the physician base of
the Sentinelles network. The study of the past fifteen years highlights that the number of tests peaked in 1993 then fell off sharply from 1995 to 2002.
The frequency of positive tests, which had been steadily dropping since 1990, shifted slightly upward in 2002. Only 11% of the tested patient now belongs
to a very high-risk group.
At the same
time as the previous project (where the recourse to care is addressed in a fairly general manner, by typologies of the recourse modes), we intend to
develop two complementary projects that will specifically attempt to understand the associations of the same factors on the recourse to HIV screening, on
the one hand, and on the recourse to female cancer screening, on the other. We hypothesise that the three above-mentioned aspects are determining factors
explaining reported insufficient recourse in (and from the standpoint of) public health.
Indeed the efficiency of the current French HIV screening system is imperfect,
especially if one looks at the sizeable share of HIV infected patients who learn that they are HIV positive when they are diagnosed with Aids and of
screened patients whose therapeutic care has been delayed overlong. This is why it would be particularly productive to draw on the assets of the SIRS
cohort (Ile-de-France region, over-representation of underprivileged neighbourhoods, detailed data on people’s migratory origins, among others) to advance
in the analysis of the social determinants of the recourse to screening.
For the recourse to female cancer screening, the SIRS cohort will address the
methods and circumstances of the recourse to mammograms and cervical smears - both medically recommended screening procedures. In the first case, a
“competition” between the recourse to individual screening and the organised screening programme exists in the Paris area and throughout France. Extant
low re-attendance rate in the organised screening programme and quite sizeable social and geographic inequalities need to be characterised more precisely.
For cervical smears, individual diagnosis is widespread but seems to leave a large share of women by the wayside (only 54% of 20 to 69 year-old women had
at least one cervical smear taken within the past three years, from 1998 to 2000). Here too, the reasons or the social and geographic stratification are
not precisely known. The project will be rolled out in collaboration with Apsp (E. Cadot) and with INSERM
U822 (V. Ringa).
3. Uses and Practices for
Health Information Search on the Internet (E. Renahy, P. Chauvin)
The project starts with the observable fact that the Internet provides access
(for oneself, friends or relatives) to medical knowledge and information on the care system. Overall project goal is to describe the social stratification
of Internet use when searching for health information and its consequences on health and care management. Based on a review of the literature  and
qualitative interviews, a questionnaire was designed and integrated into the first SIRS cohort wave. Although our preliminary analyses showed that the
Internet might be a useful media for health information dissemination to young adults, the ‘active’ search for health information on the Internet was
usually done by people who already had access to other sources of information. We are now focussing on describing the social stratification of an
accumulation of obstacles, to which the usual determinants of the digital divide, and the determinants associated with health information search in
general should be added. We are also analysing to what extent such use is linked to individuals’ integration and social roles.
Another survey of only Internet users ha also been conducted (the WHIST study).
In 2007, the online questionnaire was put on numerous French-speaking ‘general public’ websites, as part of INSERM partnerships. The purpose is to
accurately describe the uses and (Internet user perceived) consequences of the health information search specifically on the use modes of the care system.
The research is the subject of E. Rehany’s PhD thesis. For the call for contributions for second-tier processing issued by the Living Conditions Division
at Insee, we plan to complete our analyses on the data from the Permanent Survey on Household Living
Conditions (additional questionnaire on information and communications technologies).
Track 2. The Psychosocial and Geographic Determinants of Health
1. Effects of the
residential, physical and social, context on health and influence mechanisms: applications to coronary pathologies (B. Chaix)
have been able to assess the impacts of the country’s economic characteristics (first on a fairly large departmental scale) on a series of behaviours
and/or risk factors, i.e., smoking, drinking, lack of physical activity and obesity, thanks to a contextual analysis of the data from the
Inpes Health Barometer. Another example of analysis (conducted with Swedish georeferenced data) has highlighted the link between the
socioeconomic level of the residential context and the incidence of mental disorders linked to the abuse of psychoactive substances. With the French and
Swedish data, we have also shown the advantage of using models other than multi-level models (specifically geostatistical models) and of determining the
scale of contextual impact maximisation (by defining growing ‘adaptive spatial areas’ systematically, for instance). The spatial approach, which models
geographic variations and defines the explanatory factors of the context in a continuous space rather than in a space broken down into arbitrary zones, is
a major methodological innovation in contextual analysis.
Project goals are to determine which characteristics of the residential context
are associated with coronary disease and with its risk factor, by distinguishing the socio-demographic characteristics of the neighbourhoods
(socioeconomic level, population density, and so on), physical environment (infrastructures and services, maintenance, pollution and noise exposure, built
environment), and social interaction environment. An original project approach is to take account – at the individual level as well as characteristics of
the residential context – of a wide range of lived experiences in the neighbourhood (attachment to the neighbourhood, social stressors, residential
stigmatisation, residential captivity, social integration, social support and so on). Several analyses are underway on cardiovascular morbidity and risk
factor incidence data from the LOMAS-2 base (Lund University, Sweden), the team’s data from the SIRS cohort, and the data (that was geocoded on this
occasion) from the PRIME (INSERM U780) cohorts. Based on the data from the PRIME cohort, we use multi-level models and structural equations to show, for
instance, that more than half of the negative impacts of neighbourhood poverty level on blood pressure are mediated by the strong prevalence of obesity in
The RECORD cohort study
For a more accurate study of all these factors, we are developing a special
cohort project called RECORD (Residential Environment and CORonary heart Disease) that matches the clinical, biological, psychological and medical
data collected by the Paris Centre for Preventive and Clinical Investigations at its different Paris and suburban venues with the social and residential
data collected specifically via self-questionnaire. The project also plans to monitor and detect prospectively the cardiovascular morbimortality of the
participants through the National hospital based health information system (PMSI) and the National mortality surveillance system (Cépi-DC). The plan is to
recruit 7,000 individuals, ranging from age 30 to 79 and residing in the 144 selected Ile-de-France municipalities, in 2007. The purpose is to have a
large socio-geographic diversity in the sample. A second wave (by mail) is scheduled for 2008.
Similar to the SIRS cohort, participants will be geocoded and contextual data
taken at different scales will be compiled in a huge database developed in the team’s geographic information system. The contextual data comes either from
an aggregate of participant answers (ecometric approach), or from outside sources (Insee, General Tax
Directorate, Paris Chamber of Notary Publics, CAF, Institute for Land and Urban Management of the Ile-de-France Region, Airparif, Regional Directorate for
Infrastructures, the ministries for agriculture and for youth and sports, and Ign).
2. Medium and long-term consequences of serious events experienced during
childhood on psychosocial adjustment (C. Roustit, P. Chauvin)
The team and the Quebec Institute of Statistics signed an agreement granting
us preferred access to the data from the 1999 representative survey on Quebec teenage health (random sample of more than 2,000 teenagers and their
parents). Thanks to this data, we have shown how parental separation is associated with 4 indicators of psychosocial maladjustment in children
(internalised and/or externalised disorders, consumption of drugs and/or alcohol). For internalised disorders, the impact is largely explained by the
existence of inter-parental violence whereas for the other 3 indicators, the family break-up and the different characteristics of the family modus
operandi after the separation seem to have independent impacts.  We are now looking at these results more closely, analysing the links between
anxiodepressive syndromes in the parent or parents and the psychosocial maladjustment of the children, and assessing the protective role of the (intra and
extra familial) social support the children receive.
3. Social determinants of
diet, overweight, and obesity (J. Martin, F. Grillo, P. Chauvin)
analyses of the SIRS cohort highlight that obesity is associated with individuals’ socioeconomic status as well as with their conjugal and family
situation and geographic origins, whereas certain contextual variables (food supply and sports facilities among others) are not determinant. This
observable fact (and the limitation of the available data in the first waves of the cohort) has prompted us to develop a new project to take a closer look
at the social inequalities of dietary behaviours and corpulence, and study their socioeconomic, psychosocial, and geographic determinants.
More precisely, 4 aspects of dietary practices will be distinguished
(food supply, preparing, taking and eating meals). Questions on the four aspects will be asked during the next SIRS wave to test (through a qualitative
and statistical approach) 4 main hypotheses: (1) diet is affected by the accumulation of social vulnerabilities (financial difficulties, social isolation,
precarious employment, among others); (2) certain forms of the geographical relegation of unprivileged
populations, and more broadly the features of the residential neighbourhoods, have consequences on dietary behaviours; (3) the perception
of a relation – and its content – between people’s diet and health depends on their living conditions, psychological characteristics, and social ties and
their responsiveness and reception of nutritional information messages; (4)
in poor households, dietary practices are subject to, and reflect all the experienced difficulties. In this
context, the diet does not ensure its structuring role but follows and strengthens individuals’ social and familial constraints.
The team-coordinated project is developed in collaboration with the
Laboratory for research on consumption
(Corela) and ERIS.
Migratory origin has regularly
been pinpointed as a factor that is often determinant (if not studied in itself) in numerous past works by the team.
Previous Research (B. Larouzé, V. Massari)
After several studies on the
diagnosis of tuberculoses with negative baciloscopy [3, 53] and on the interactions between tuberculosis and HIV-2 in Subsaharan Africa , a
multidisciplinary programme was rolled out in the prisons of Rio de Janeiro (in collaboration with the Oswaldo-Cruz Foundation and the Health Coordination
of the Prisons of Rio de Janeiro) to detail the prevalence of tuberculosis (from 4 to 9% in the studied prisons), its determinants, and the most
appropriate screening strategies [36, 43, 48]. The research-action programme in the prisons, in collaboration with the LCS (Paris 7) and HEC, involved the
prisoners, prison guards, and other players of prison life. The purpose was to identify the obstacles to rolling out the tuberculosis control programmes.
 The research was instrumental in getting the Brazilian State to issue new regulatory measures and served as the basis for nationwide discussions
during a recent meeting on TB fighting strategies in prisons, under the aegis of the Global Fund to Fight Tuberculosis-Brazil and the Ministry for Health.
The research will continue, process the huge amount of material that was collected during the research, and assess the impact of implemented strategies
and their feasibility.
Another ANRS funded programme that
was rolled out by G. Leloup (doctorate candidate) is dedicated to the HIV-Aids control policy in Brazil. It brings together 2 French research laboratories
(ours and the GAPP/CNRS/Ecole Normale Supérieure de Cachan) and 2 Brazilian research laboratories (EBAPE/ Getulio Vargas Foundation and the
Institute for Social Medicine at the State University of Rio de Janeiro). The research studies two very different Brazilian states in terms of resources
and health system organisation. It uses the methods and approach of public policy analysis to study the response of the Brazilian health system to the
evolution of the HIV-Aids epidemic and the problems accessing prevention and care that result from the said evolution.
research track addresses health and the recourse to care of immigrants in France. Its overall objective is to study whether – and to what extent – certain
social determinants come in to play specifically in immigrants’ health and recourse to care, and whether the determinants are specifically linked to
immigration (country of origin, immigration conditions: legal or not, personal or familial, old or recent, and so on) and/or commonly refer to the
multiple aspects of social precariousness. The roles of health, disease, and care needs (its subjective and objective aspects) in the initial decision to
emigrate and then stay in France will be studied. In the country of origin, the role of health determinants (diseases and medical care needs) and their
interactions with other social factors – economic, financial, family, social or political factors among others – in the individuals’ migratory projects
are still poorly known. Although it seems that, overall, the most healthy individuals are the most likely to emigrate (migration bias), on the other hand,
ill people who do not find the appropriate care in their own country may want to emigrate (temporarily or definitively) to a country where the care is
available. Such migrations obviously depend on the individuals’ resources (and not only their financial resources). In the host countries, morbid
disorders – and/or merely ageing (see the mean age of the generations of migrant workers who arrived in France in the sixties) – may mean that any hope of
returning to the country of origin has been put on hold or abandoned, if the required care is not available there, sometimes at the cost of extremely
precarious living conditions. Some administrative indicators seem to suggest that the frequency of these situations is rising in France but their social
and sanitary characterisation in terms of public health is still little studied.
issues arise in an international situation marked by 5 strong trends: (1) the general intensification of international human migrations; (2) the
persistence of profound inequalities in the care supply between the North and South; (3) restrictive amendments to European (and specifically French)
migratory policies; (4) recurrent discussions on the consequences and the social, political, economic, ethic and sanitary stakes of the three combined
trends; (5) the questions of the development aid institutions concerning the impact of investments in the health sector on migratory flows.
1. Migration and medical care (J. Lebas, P. Chauvin)
developing a research programme in collaboration with the French Agency for Development (AFD) on the place of health and care needs in the South-North
programme will include an inventory of French and international public health and soft science literature on the topic and the set-up of a
multidisciplinary network of researchers involved or interested in the issue, the inventory and analysis of extant French data, and the roll-out of
surveys for comparing the processes at work in different pathologies (depending whether they are curable or not, their duration, survival, and prognosis
for spontaneous cure or for cure following treatment, the availability of treatment in the countries of origin), and in the different countries of origin
(according to the level of public spending for health but also to the size of their migratory flow to France). The goal is to combine qualitative and
statistical surveys of migrants in France and of populations in the countries of origin.
partnership with InVS and AFD, we are rolling out a representative survey of the general population on the social determinants of health and the recourse
to care in the very specific context of Mayotte island. The geographic and cultural nearness of this French territory with some of the world’s poorest
countries (namely the Comoros and Madagascar) generates extremely high migratory tensions. The survey will be reproduced in another French ‘border’
territory, French Guiana.
2. Health and recourse to
health care of illegal foreigners in Europe (P. Chauvin, I. Parizot)
In 2006, we
started working with the European Observatory of Médecins du Monde to measure and compare illegal foreigners’ state of health and access to care in
different European countries. The first test survey of physicians treating illegal foreigners at 21 free clinics in 7 countries evidenced vast differences
between countries in terms of the frequency and the nature of the (legal, administrative, linguistic, lack of information, care refused, and so on)
hurdles encountered when attempting to access care, including for health problems that might have serious sanitary consequences for the individual or the
community. In 2008, another survey has been planned with a larger sample of individuals, including more detailed questions on the circumstances of the
migration, living conditions and social integration of the people in the host country and a medical assessment of the needs and delays in receiving care.
3. People of foreign descent
and migrants’ health and recourse to healthcare (G. King)
analyses based on SIRS cohort data highlight the existence of notable differences according to the nationality of the individuals and/or of their parents,
with regards to perceived health, certain health behaviours, and the recourse to care. Our goal is to continue characterising the associations, determine
to what extent they are mediated by other individual social characteristics, and conversely, whether the social gradients observed in the general
population are or are not found in the different migratory groups. We will also take a closer look at certain explanatory hypotheses (specifically in
terms of representations of health and medicine or lived experiences of discrimination in the health system). G. King, who has worked on the issue of
disparities in health behaviours and studied their psychosocial and contextual determinants in the Afro-American minorities in the United States, will
also conduct a comparative analysis of the individual and geographic inequalities of tobacco addiction between the Paris area and certain US cities, and
the role of socioeconomic and ‘migratory’ (France) or ‘ethnic’ (United States) characteristics.
