Teenage childbearing and school dropout in a sample of 18,791 single mothers in Cameroon
Background: Adolescent childbearing increases the risk of adverse health and social consequences including school dropout (SDO). However, it remains unclear why some teenage mothers drop out of school and others do not, especially in sub-Saharan Africa settings. We aimed to investigate the background and behavioral characteristics of single mothers, associated with school dropout in a sample of 18,791 Cameroonian girls, who had their first child during adolescence. Methods: We used data from a national registry of single mothers, collected during the years 2005â2008 and 2010â2011. Both bivariate analysis and logistic binary regression models were used to explore the relationship between adolescence motherhood and SDO controlling for a range of socio-economic, family, sexual and health seeking behavior characteristics. Results: Among the 18,791 single mothers, 41.6% had dropped out of school because of pregnancy. The multivariable regression model showed that SDO was more common in those who were evicted from their parental home (aOR: 1.85; 95% CI: 1.69â2.04), those who declared having other single mothers in their family (aOR: 1.16; 95% CI 1.08â1.25) and in mothers who had their first child before 15. Using modern contraceptive methods, having declared no sexual partner during the last year and having less than 2 children were associated with a reduced likelihood of school dropout. Conclusions: Strong social support is essential to ensure school continuity in this vulnerable population. Dropping out of school may put the teenage mother more at risk of unsafe health behaviour and new pregnancies

Consumption of dairy products and cardiovascular disease risk: results from the French prospective cohort NutriNet-Santé
In France, dairy products contribute to dietary saturated fat intake, of which reduced consumption is often recommended for cardiovascular disease (CVD) prevention. Epidemiological evidence on the association between dairy consumption and CVD risk remains unclear, suggesting either null or inverse associations. This study aimed to investigate the associations between dairy consumption (overall and specific foods) and CVD risk in a large cohort of French adults. This prospective analysis included participants aged â„ 18 years from the NutriNet-SantĂ© cohort (2009â2019). Daily dietary intakes were collected using 24h-dietary records. Total dairy, milk, cheese, yogurts, fermented and reduced-fat dairy intakes were investigated. CVD cases (n=1,952) included cerebrovascular (n=878 cases) and coronary heart diseases (CHD, n=1,219 cases). Multivariable Cox models were performed to investigate associations. This analysis included n=104,805 French adults (mean age at baseline 42.8 years (SD 14.6), mean follow-up 5.5 years (SD 3.0, i.e. 579,155 persons years). There were no significant associations between dairy intakes and total CVD or CHD risks. However, the consumption of at least 160 g/d of fermented dairy (e.g. cheese and yogurts) was associated with a reduced risk of cerebrovascular diseases compared to intakes below 57 g/d (HR=0.81 [0.66-0.98], p-trend=0.01). Despite being a major dietary source of saturated fats, dairy consumption was not associated with CVD or CHD risks in this study. However, fermented dairy was associated with a lower cerebrovascular disease risk. Robust randomized controlled trials are needed to further assess the impact of consuming different dairy foods on CVD risk and potential underlying mechanisms
Food metabolomics applied in cohorts to accelerate the discovery of nutritional biomarkers
communication orale : Claudine ManachThe Second International Congress of Translational Research in Human Nutrition is organised by the Research Centre in Human Nutrition (CRNH) of Auvergne, of which INRA is a member, in collaboration with NuGO, European Association of universities and research institutes in the field of nutrigenomics.The purpose of dietary assessment is to estimate usual and recent intake of foods, nutrients, bioactive compounds and food contaminants for exploration of associations with health outcomes and monitoring of population nutritional status. These data are still extremely difficult to obtain. Methods currently used are based on dietary questionnaires which have inherent limitations linked to self-reporting. A complementary approach to questionnaires is the use of biomarkers. However, only a few biomarkers have been properly validated, which do not cover the wide range offoods consumed. Metabolomics has emerged as a promising approach to discover nutritional biomarkers. Typically, plasma or urine samples collected before and after acute intake of a specific food are profiled using NMR or high resolution Mass Spectrometry (MS) and compared usingmultivariate statistics to pinpoint the signals reflecting the consumption of the target food. In a proof-of-concept study on citrus, we showed that urine profiling of cohort subjects stratified by consumption could be a more effective strategy for discovery of sensitive biomarkers of intake

Is the relationship between common mental disorder and adiposity bidirectional? Prospective analyses of a UK general population-based study
The direction of the association between mental health and adiposity is poorly understood. Our objective was to empirically examine this link in a UK study. This is a prospective cohort study of 3 388 people (men) aged >= 18 years at study induction who participated in both the UK Health and Lifestyle Survey at baseline (HALS-1, 1984/1985) and the re-survey (HALS-2, 1991/1992). At both survey examinations, body mass index, waist circumference and self-reported common mental disorder (the 30-item General Health Questionnaire, GHQ) were measured. Logistic regression models were used to compute odds ratios (OR) and accompanying 95% confidence intervals (CI) for the associations between (1) baseline common mental disorder (QHQ score > 4) and subsequent general and abdominal obesity and (2) baseline general and abdominal obesity and re-survey common mental disorders. After controlling for a range of covariates, participants with common mental disorder at baseline experienced greater odds of subsequently becoming overweight (women, OR: 1.30, 1.03 - 1.64; men, 1.05, 0.81 -1.38) and obese (women, 1.26, 0.82 - 1.94; men, OR: 2.10, 1.23 - 3.55) than those who were free of common mental disorder. Similarly, having baseline common mental health disorder was also related to a greater risk of developing moderate (1.57, 1.21 - 2.04) and severe (1.48, 1.09 - 2.01) abdominal obesity (women only). Baseline general or abdominal obesity was not associated with the risk of future common mental disorder. These findings of the present study suggest that the direction of association between common mental disorders and adiposity is from common mental disorder to increased future risk of adiposity as opposed to the converse

Obesity and Migraine: Effect Modification by Gender and Perceived Stress
International audienceBackground: The association between obesity and migraine has been established; however, it is unclear whether it varies by perceived stress within each gender. Methods: This crosssectional study used data from the ongoing NutriNet-Sante e-cohort with enrollees from the general population. Anthropometric and migraine data were provided via self-report questionnaires (2013-2016). Migraine was defined using established criteria. Perceived stress was assessed with Cohen's Perceived Stress Scale-10. Associations were estimated via gender-and stress-stratified multivariable polytomous logistic regression models. Results: Among 32,835 participants with complete data (75% women; mean age = 51.9 +/- 13.8 years), 34% reported no headache, 44% non-migraine headache, and 22% migraine with or without aura during one's lifetime. In these groups, obesity was present in 8.6, 9.9, and 11.6%, respectively. Stress was a significant moderator of the obesity-migraine association only among women. The largest significant adjusted odds ratio (aOR) was found between obesity and migraine in women with high stress (aOR 1.61, 95% CI 1.35-1.91). Conclusions: We found support for gender-and stress-dependent associations between obesity and migraine using a large, heterogeneous adult sample. This underscores the need for evidence-based strategies for weight loss and stress reduction for female migraineurs
Impact of orlistat initiation on cardiovascular treatment use: a 6-year population-based cohort study
International audienceBackground: Trials of weight-loss drugs indicate some benefits on lipids, blood glucose, or blood pressure levels. Since obesity is associated with increased cardiovascular (CV) medication use and pharmaceutical costs, weight-loss drug use could beneficially impact CV medication use. Objective: We examined the temporal associations between CV drugs use 3 years before and after the initiaion of orlistat, a weight-loss drug. Design: An historical cohort study in the PHARMO pharmacy registry among new users of orlistat, who were in the database at least 3 years before and after such drug initiation. We assessed the prevalence of use of antihypertensive, antidiabetic, and lipid-lowering drugs within a 6-month period before and after orlistat initiation. Slopes and changes in slopes between these two periods were calculated using logistic generalized estimating equations and odds ratios (OR) with 95% confidence intervals (CI) are presented. Results: A total of 6139 subjects had a prescription of orlistat between January 1992 and May 2009. Mean +/- SD age was 46.5 +/- 12.5 years, with a majority of female (88.7%). Use of antihypertensive, antidiabetic, and lipid-lowering drugs increased over time, but after start of orlistat the slopes levelled-off. Initiation of orlistat resulted in a significant change in slope for antihypertensive (OR 0.79; 95% CI 0.77-0.81), antidiabetic (0.86; 0.83-0.90), and lipid-lowering drugs (0.84; 0.81-0.88). Conclusions: Our data suggest a potential cost-effectiveness of orlistat, with a reduction in any cardiovascular comedication use over time. By potentially reducing costs of other medications use, orlistat remains as a unique option for tackling the obesity epidemic
Ten-year change in blood pressure levels and prevalence of hypertension in urban and rural Cameroon.: Blood pressure changes in Cameroon
International audienceBlood pressure levels of this population have deteriorated over time, and the prevalence of hypertension has increased by twofold to fivefold. Adverse effects of risk factors could account for some of these changes. Prevention and control programmes are needed to reverse these trends and to avoid the looming complications
