Gender differences in the association between socioeconomic status and hypertension in France: A cross-sectional analysis of the CONSTANCES cohort.

BACKGROUND: Hypertension prevalence increases when socioeconomic status decreases but gender differences in the relationship between socioeconomic status and hypertension have been less studied. This work aimed to explore the pattern of associations between three indicators of socioeconomic status at individual, household, and municipal levels with hypertension across genders in a large sample of French adults from the CONSTANCES cohort. METHODS: Using data at inclusion from 59 805 participants (52% women) aged 25-69 years and recruited between 2012 and 2015, multilevel log-Poisson regressions with robust variance estimates were used to assess the associations of Relative Index of Inequality in education, monthly income per consumption unit and residential deprivation with hypertension. Modifying effects of gender and age in those associations were tested. RESULTS: Hypertension prevalence was higher in men than in women. Steep socioeconomic gradients of hypertension were observed for the three socioeconomic indicators in both genders and from the youngest to the oldest age class. Socioeconomic inequalities, especially educational inequalities, were larger among women than men: Relative Index of Inequality for highest versus lowest education among the 25-34 years were 0.43 [95%-confidence interval = 0.28-0.67] in women and 0.70 [95%-confidence interval = 0.53-0.92] in men. With increasing age, socioeconomic gradients of hypertension eased in men and even more in women so that gender differences decreased. CONCLUSIONS: In this cross-sectional analysis of a large sample of adults, prevalence of hypertension was higher in men than in women. Moreover, socioeconomic status and especially education displayed a stronger association with hypertension prevalence in women compared to men. Reducing inequalities in hypertension may require gender-specific approaches.

Geographical variations in the prevalence of hypertension in France: Cross-sectional analysis of the CONSTANCES cohort.

AIMS: While international variations in the prevalence of hypertension are well described, less is known about intra-national disparities and their determinants. We wanted to describe the variations in hypertension prevalence within France and to determine how much lifestyle and socioeconomic factors contributed to explain these regional variations. METHODS: Participants (62,247 French adults aged 18 to 69 years) were recruited in the 16 centres of the CONSTANCES study between 2012 and 2015. Hypertension was defined as blood pressure higher than 140/90 mmHg and/or taking antihypertensive medications. The contribution of lifestyle and socioeconomic factors to hypertension prevalence variations among centres was examined using sequential hierarchical logistic models. RESULTS: Hypertension prevalence was 37.3% (95% confidence interval (CI) = 36.6-38.0) in men and 23.2% (95% CI = 22.7-23.8) in women. Hypertension prevalence rates varied by almost two-fold among centres (1.9 in men, 1.6 in women) with the highest prevalence in the north and the east of France. Body mass index was strongly associated with hypertension in women (odds ratio (OR)1-unit increase = 1.11 (95% CI = 1.11-1.12)) and was the highest contributor to between-centre variations (27% in women), followed by socioeconomic characteristics (e.g. ORhigh versus low education = 0.85 (95% CI = 0.83-0.87), contributing to 14% of variations in women). Together, family history of hypertension, body mass index, education, occupation and residential area socioeconomic level explained about 30% and 40% of between-centre variations in men and women, respectively. CONCLUSION: Hypertension prevalence greatly varies among French regions and this is partly explained by known lifestyle and socioeconomic factors. Nevertheless, these variations and all the hypertension determinants have not been fully deciphered yet.

Use of state sequence analysis for care pathway analysis: The example of multiple sclerosis.

The concept of care pathways is increasingly being used to enhance the quality of care and to optimize the use of resources for health care. We here propose an innovative method in epidemiology that is derived from social sciences: state sequence analysis (SSA). This method takes into account the chronology of care consumption and allows for identification of specific patterns. A process for using SSA in the health area is proposed and discussed. The main steps are: data coding, measurement of dissimilarities between sequences (focusing on optimal matching methods and the choice of related costs), and application of a clustering method to obtain a typology of sequence patterns. As an example of its use in the health area, SSA was employed to analyse care pathways of a random sample of patients with multiple sclerosis. This sample has been selected from the main French healthcare database covering the period 2007 to 2013 (n = 1 000). A five-cluster typology was obtained which allowed distinction of care consumption groups. Overall, about half of the patients had low care consumption, about one quarter had medium to high consumption, and another quarter had high consumption. We conclude that state sequence analysis is an innovative and flexible methodology that is worth considering in health care research.

Sex differences in adherence to antihypertensive treatment in patients aged above 55: The French League Against Hypertension Survey (FLAHS).

Despite the availability of efficient therapies to reduce the risk of cardiovascular complications, poor adherence to antihypertensive (anti-HTN) drugs is frequent, especially during the first year of treatment and among uncontrolled/resistant hypertensive patients. The aim of the study was to identify factors associated with adherence to anti-HTN treatment and to examine whether they differ across sex. A total of 2743 treated hypertensive participants to the cross-sectional Metascope survey (France, 2015) aged 55 years or more were included. The authors measured adherence to anti-HTN treatment using the 6-item Girerd compliance test. Variations in adherence were examined using the Rao-Scott statistics and Poisson regression. Overall, 63.6% of participants were adherent to anti-HTN treatment. Adherence was more frequent among women than men (69% vs 58%, P < 10-4 ). For both sexes, level of adherence was positively associated with age (P < 10-4 ), but inversely associated with number of anti-HTN tablets, number of tablets taken for metabolic diseases, history of cardiovascular diseases, number of other chronic diseases (all P < 10-4 ). The inverse relationship between adherence and the number of anti-HTN tablets significantly differed between sexes (P < 10-4 ): Adherence decreased sharply when taking two or more anti-HTN tablets in men, whereas the decrease in women was only observed when taking three or more anti-HTN tablets. This study suggests that adherence to anti-HTN treatment is higher among women, decreases with the number of tablets prescribed, and differentially so across sex. Reducing the number of tablets for anti-HTN treatment may improve adherence, especially among men and patients with multiple comorbidities.

Socio-Economic Determinants of the Need for Dental Care in Adults.

BACKGROUND: Oral health has improved in France. However, there are still inequalities related to the socio-economic status. OBJECTIVES: The aim of this study was to measure the prevalence of dental care needs in an adult population and to identify the demographic, socio-economic and behavioral variables that may explain variations in this parameter. METHODS: A cross-sectional analysis of the French SIRS cohort (n = 2,997 adults from the Paris region; 2010 data) was carried out to determine the prevalence of self-reported dental care needs relative to demographic, socio-economic and behavioral variables. A logistic regression model was used to identify the variables that were most strongly associated with the level of need. RESULTS: In 2010, the prevalence of the need for dental care in the SIRS cohort was 35.0% (95% CI [32.3-37.8]). It was lower in people with higher education levels (31.3% [27.9-34.6]), without immigrant background (31.3% [28.0-34.6]) and with comprehensive health insurance (social security + complementary health cover; 32.8% [30.2-35.4]). It decreased as the socio-economic status increased, but without following a strict linear change. It was also lower among individuals who had a dental check-up visit in the previous two years. In multivariate analyses, the socioeconomic variables most strongly associated with the need for dental care were: educational attainment (OR = 1.21 [1.02-1.44]), income level (OR = 1.66 [1.92-2.12]) and national origin (OR = 1.53 [1.26-1.86]). CONCLUSION: These results confirm that the prevalence of dental care needs is higher among adults with low socio-economic status. Education level, income level and also national origin were more strongly associated with the need for dental care than insurance cover level.

Civil society engagement in innovation and research through the European Public Health Association.

BACKGROUND: The European Public Health Association (EUPHA) proposed and led PHIRE (Public Health Innovation and Research in Europe), with co-financing by the European Commission, to assess public health innovation and research at national level in Europe. PHIRE was also designed to promote organizational development and capacity building of EUPHA. We assess the success and limitations of using EUPHA's participative structures. METHODS: In total, 30 European countries were included-27 EU countries, Iceland, Norway and Switzerland. EUPHA thematic section presidents were asked to identify country informants to report, through a web-based questionnaire, on eight public health innovations. National public health associations (EUPHA member organizations) were requested to identify their national public health research programmes and calls, review the health research system, coordinate a stakeholder workshop and provide a national report. The section and national reports were assessed for responses and completeness. RESULTS: Half of the final responding CIs were members of EUPHA sections and the other half gained from other sources. Experts declined to respond for reasons including lack of time, knowledge of the innovation or funding. National public health associations held PHIRE workshops with Ministries of Health in 14 countries; information for 10 countries was gained through discussions within the national association, or country visits by PHIRE partners. Six countries provided no response. Some national associations had too weak organizational structures for the work or insufficient financial resources or criticism of the project. CONCLUSION: EUPHA is the leading civil society organization giving support to public health research in Europe. PHIRE created new knowledge and supported organizational development. EUPHA sections gained expert reports on public health innovations in European countries and national public health associations reported on national public health research systems. Significant advances could be made if the European Commission worked more directly with EUPHA's expert members and with the national public health associations.

Competitive funding and structures for public health research in European countries.

INTRODUCTION: The European Union is giving increasing emphasis to research as a driver for innovation and economic development. The European collaborative study PHIRE (Public Health Innovation and Research in Europe) investigated the funding and structures of public health research at national level in European countries. METHODS: Background materials were prepared for national public health associations of European countries to hold workshops or discussions with research and policy stakeholders on their public health research systems. The reports, supplemented from internet sources for 23 EU countries (four did not contribute), provided information for framework analysis. RESULTS: All countries have public funding and administrative structures for research, but structures for public health research are more varied. In most countries, competitive health research funding is controlled by the Ministry of Science, with little input from the Ministry of Health. In four countries, Ministries of Health provide competitive funding alongside Ministries of Science, and in two countries there is a single health research council. There is no comparative reporting of public health research funding, and little connection with European public health research programmes. CONCLUSION: Europe needs a comprehensive picture of national and regional systems of public health research, in order to critically assess them and better adapt to changes and challenges, and to achieve a European Research Area for public health.

Incidence of ischaemic stroke according to income level among older people: the 3C study.

BACKGROUND: stroke has been shown to follow a social gradient with incidence rising as socioeconomic status decreases. OBJECTIVE: to examine the relationship between socioeconomic status and ischaemic stroke risk amongst older people. SETTING: the Cities of Bordeaux, Dijon and Montpellier in France. SUBJECTS AND METHODS: nine thousand and two hundred and ninety-four non-institutionalised persons aged 65 years or more followed for 6 years. RESULTS: the distribution of cardiovascular risks factors was consistent with the classical finding of more favourable risk profiles among the advantaged socioeconomic groups. One hundred and thirty-six individuals developed a first ever ischaemic stroke (incidence rate: 3.2 per 1,000 py (person-years), 95% CI 2.7-3.8). The age- and sex-adjusted incidence of ischaemic stroke increased with increasing level of income (from 2.4 to 4.1 per 1,000 py, P = 0.04). In the multivariable analysis adjusting for cardiovascular risk factors, the higher income group displayed a 80% increased risk of ischaemic stroke compared with less wealthy participants (hazards ratio 1.77, 95% CI 1.20-2.61). CONCLUSIONS: in this community-based sample of older individuals, a higher level of household income was associated with a higher risk of ischaemic stroke, a reversal of the social gradient usually reported in younger age groups. Selective survival is one of the potential explanations for this unexpected finding.

Health needs and public health functions addressed in French public health journals.

BACKGROUND: Our aim, as part of the collaborative study SPHERE (Strengthening Public Health Research in Europe), was to describe public health publications in the French language according to health needs and public health functions. METHOD: All articles published in six French public health journals, and one French/English language Canadian journal, over the period 1995-2004, were retrieved from three electronic databases. Original research articles were indexed by hand according to one main domain of health need, based on Global Burden of Disease categories, and into one of four public health functions. RESULTS: After removing duplicates, 3984 original research articles were identified. Only 51% could be allocated to a health needs code. Of these, 71% were about non-communicable diseases, 25% communicable, maternal and perinatal conditions and 5% injuries. This compared only moderately with the global burden of disease for France (84, 5 and 11%, respectively). The other articles addressed health determinants, such as behavioural or environmental exposures, or a methodological issue. Ninety-two percent of the articles could be assigned a public health function code. Health monitoring and health services research accounted for 80% of references from French journals. Only 9% of articles from French journals were related to prevention, which was lower than that in the Canadian journal (17%). Only 1% of articles dealt with legislation. CONCLUSION: The distribution of articles in French public health journals broadly follows the distribution of health needs. History and data availability may explain the extra research focus on communicable diseases and maternal and child health research. Injuries, and prevention, are topics which appear to be under-represented in French language journals.
