Factors associated with compliance with barrier gestures and social distancing measures in France.

BACKGROUND: The COVID-19 pandemic led many countries to drastically limit social activities. The objective of this study is to describe the factors associated with compliance with protective measures and social distancing in the general adult population in France, between March and December 2020 (first and second waves of the epidemic), before vaccination began at the end of December 2020. METHOD: The data come from the CoviPrev repeated cross-sectional descriptive survey, conducted between March 2020 and December 2022 in metropolitan France. The data collected from March to December 2020 (19 survey waves), from a panel representative of the general population, were used. Three periods were defined: the first epidemic wave (March-April), the inter-wave period (May-June) and the second epidemic wave (November-December). A compliance score was constructed to measure systematic compliance with the five main measures. The association between systematic compliance and different variables (sociodemographic, mental health, level of health literacy, perceived severity of COVID-19, confidence in government, perceived effectiveness of the measures) was described using bivariate and multivariate logistic regression models, using the statistical software R. RESULTS: Systematic compliance with the preventive measures changed over time. Regardless of the period, being a woman, being over 50, perceiving COVID-19 as severe, having a high level of health literacy or anxiety were positively associated with compliance. Having a child under 16 years of age and perceiving the measures as effective were positively associated with compliance with the protective measures during the epidemic waves; conversely, having a high level of depression, living alone, not working were negatively associated in the first epidemic wave. Finally, during the inter-wave period, living in an area heavily affected during the first wave and having a high level of education were positively and negatively associated with systematic compliance with the preventive measures, respectively. CONCLUSION: The factors associated with compliance with the protective measures and social distancing evolved during the epidemic. Monitoring this evolution, in order to adapt communication and awareness strategies, is essential in the context of pandemic response.

Innovative use of data sources: a cross-sectional study of data linkage and artificial intelligence practices across European countries.

BACKGROUND: The availability of data generated from different sources is increasing with the possibility to link these data sources with each other. However, linked administrative data can be complex to use and may require advanced expertise and skills in statistical analysis. The main objectives of this study were to describe the current use of data linkage at the individual level and artificial intelligence (AI) in routine public health activities, to identify the related estimated health indicators (i.e., outcome and intervention indicators) and health determinants of non-communicable diseases and the obstacles to linking different data sources. METHOD: We performed a survey across European countries to explore the current practices applied by national institutes of public health, health information and statistics for innovative use of data sources (i.e., the use of data linkage and/or AI). RESULTS: The use of data linkage and AI at national institutes of public health, health information and statistics in Europe varies. The majority of European countries use data linkage in routine by applying a deterministic method or a combination of two types of linkages (i.e., deterministic & probabilistic) for public health surveillance and research purposes. The use of AI to estimate health indicators is not frequent at national institutes of public health, health information and statistics. Using linked data, 46 health outcome indicators, 34 health determinants and 23 health intervention indicators were estimated in routine. The complex data regulation laws, lack of human resources, skills and problems with data governance, were reported by European countries as obstacles to routine data linkage for public health surveillance and research. CONCLUSIONS: Our results highlight that the majority of European countries have integrated data linkage in their routine public health activities but only a few use AI. A sustainable national health information system and a robust data governance framework allowing to link different data sources are essential to support evidence-informed health policy development. Building analytical capacity and raising awareness of the added value of data linkage in national institutes is necessary for improving the use of linked data in order to improve the quality of public health surveillance and monitoring activities.

Estimating sodium intake from spot urine samples at population level: a validation and application study in French adults.

The aim of this study was to assess the validity of the predictive INTERSALT equation using spot urine samples to estimate 24-h urinary Na (24-hUNa) excretion and daily Na intake among the French adult population. Among 193 French adults ('validation sample'), we assessed the validity by comparing predicted 24-hUNa excretion from spot urine and measured 24-hUNa excretion from 24-h urine collections. Spearman correlation coefficients and Bland-Altman plots were used and we calculated calibration coefficients. In a nationally representative sample of 1720 French adults ('application sample'), the calibrated predictive equation was then applied to the spot urine Na values to estimate 24-hUNa excretion and daily Na intake. In that sample, predicted Na intake was compared with that estimated from 24-h dietary recalls. Results were adjusted and corrected using calibration coefficients. In the validation sample, the measured 24-hUNa excretion was on average 14 % higher than the predicted 24-hUNa (+13 % for men and +16 % for women). Correlation between measured and predicted 24-hUNa excretion was moderate (Spearman r 0·42), and the Bland-Altman plots showed underestimation at lower excretion level and overestimation at higher level. In the application study, estimated daily salt intake was 8·0 g/d using dietary recalls, 8·1 g/d using predicted INTERSALT equation and 9·3 g/d after applying calibration coefficients calculated in the validation study. Despite overall underestimation of 24-hUNa excretion by spot urinary Na, the use of predictive INTERSALT equation remains an acceptable alternative in monitoring global Na intake/excreted in the French population but its use is not advised at the individual level.

Recent changes in sociodemographic characteristics, dietary behaviors and clinical parameters of adults receiving food assistance in France.

BACKGROUND: In 2004-2005, a survey carried out on food recipients in France revealed an alarming nutritional situation. In 2011-2012, and using a protocol similar to that of 2004-2005, our objective was to update the description of sociodemographic characteristics, dietary behaviors and clinical parameters of food assistance recipients and to analyze changes since 2004-2005. METHODS: Both surveys included multistage random sampling of adults benefitting from structures that supply food pantries and charitable grocery stores. Data on sociodemographic characteristics and dietary behaviors were collected along with weight, height and blood pressure measurements. Comparisons between the 2004-2005 (n = 883) and 2011-2012 (n = 1,058) survey observations were made, adjusting for socio-demographic changes which had occurred in the meantime. RESULTS: Since 2004-2005, proportions of food recipients ≥55 years (13.1-19.1 %), born in France (29.2-36.8 %) and employed (5.5-11.7 %) have increased; food insufficiency has decreased (95-74 %). For over half of the recipients, canned (52.4 %) and non-perishable (50.9 %) foods were obtained only from food assistance. Frequency of consumption significantly increased even after adjustment for socio-demographic changes; this was the case for dairy products (for twice a day consumption, 30.2-36.4 %), fruits and vegetables (three times a day, 7.8-13.9 %), and meat, eggs and fish (twice a day, 9.4-19.2 %). In 2011-2012, 15.6 % of men and 36.0 % of women were obese, while 44.5 and 35.1 % had high blood pressure, respectively. CONCLUSIONS: Between 2004-2005 and 2011-2012 in France, consumption of staple foods has been slightly improved in food assistance recipients. However, prevalence of cardiovascular risk factors remains high, which underlines the need for long-term efforts at better quality of foods delivered.

Correlations between Fruit, Vegetables, Fish, Vitamins, and Fatty Acids Estimated by Web-Based Nonconsecutive Dietary Records and Respective Biomarkers of Nutritional Status.

BACKGROUND: It is of major importance to measure the validity of self-reported dietary intake using web-based instruments before applying them in large-scale studies. OBJECTIVE: This study aimed to validate self-reported intake of fish, fruit and vegetables, and selected micronutrient intakes assessed by a web-based self-administered dietary record tool used in the NutriNet-Santé prospective cohort study, against the following concentration biomarkers: plasma beta carotene, vitamin C, and n-3 polyunsaturated fatty acids. PARTICIPANTS/SETTING: One hundred ninety-eight adult volunteers (103 men and 95 women, mean age=50.5 years) were included in the protocol: they completed 3 nonconsecutive-day dietary records and two blood samples were drawn 3 weeks apart. The study was conducted in the area of Paris, France, between October 2012 and May 2013. MAIN OUTCOME MEASURES: Reported fish, fruit and vegetables, and selected micronutrient intakes and plasma beta carotene, vitamin C, and n-3 polyunsaturated fatty acid levels were compared. STATISTICAL ANALYSES: Simple and adjusted Spearman's rank correlation coefficients were estimated after de-attenuation for intra-individual variation. RESULTS: Regarding food groups in men, adjusted correlations ranged from 0.20 for vegetables and plasma vitamin C to 0.49 for fruits and plasma vitamin C, and from 0.40 for fish and plasma c20:5 n-3 (eicosapentaenoic acid [EPA]) to 0.55 for fish and plasma c22:6 n-3 (docosahexaenoic acid). In women, correlations ranged from 0.13 (nonsignificant) for vegetables and plasma vitamin C to 0.41 for fruits and vegetables and plasma beta carotene, and from 0.27 for fatty fish and EPA to 0.54 for fish and EPA+docosahexaenoic acid. Regarding micronutrients, adjusted correlations ranged from 0.36 (EPA) to 0.58 (vitamin C) in men and from 0.32 (vitamin C) to 0.38 (EPA) in women. CONCLUSIONS: The findings suggest that three nonconsecutive web-based dietary records provide reasonable estimates of true intake of fruits, vegetables, fish, beta carotene, vitamin C, and n-3 fatty acids. Along with other validation studies, this study shows acceptable validity of using such diet-assessment methods in large epidemiologic surveys and broadens new perspectives for epidemiology.

[Chronic diseases: recent trends, challenges and prospects for change]. / Les maladies chroniques : tendances récentes, enjeux et perspectives d'évolution.

INTRODUCTION: The objectives were to describe available sources for epidemiological surveillance of chronic diseases, recent trends, and underlying phenomena for these changes and to deduce possible scenarios for the future. METHODS: Based on the examples of coronary heart disease, stroke, diabetes, chronic obstructive pulmonary disease (COPD) and lung cancer, the authors describe recent trends in mortality and hospitalizations in the general population. RESULTS: Exceptfor diabetes, the morbidity and mortality of the diseases considered have globally declined over the last decade. However, trends varied according to age and gender and an increase in mortality from myocardial infarction, COPD and lung cancer was observed among women under the age of 55. Overall, decreased morbidity and mortality can be explained by improvements in primary prevention (blood pressure, cholesterol, smoking among men...) and prevention of recurrences and complications. DISCUSSION: It is unclear whether these improvements will continue in the future. Aging, obesity, diabetes and smoking among women should negatively impact the medium-term morbidity and life expectancy (especially disability-free life expectancy). It is still difficult to predict future trends, as other factors could attenuate (electronic cigarettes, bariatric surgery...) or, on the contrary exacerbate (increased social inequalities in times of economic crisis, continued increase in smoking among women, diabetes...) these trends.

National trends in rate of patients hospitalized for heart failure and heart failure mortality in France, 2000-2012.

AIMS: The objectives of this study were to describe annual trends in patients hospitalized for heart failure (HF) and HF-associated mortality rates in France between 2000 and 2012. METHODS AND RESULTS: Hospital discharge data were extracted from the French National Hospitalization Database (PMSI). Mortality data were obtained from the French National Mortality Database. HF events constituting the underlying or associated cause of death were selected. Rates were age standardized using the 2010 European census population as the standard population. Time trends were tested using a Poisson regression model. In 2012, the overall age-standardized rate of patients hospitalized for HF was 246.2 per 100,000 inhabitants. The age-standardized rate of HF-associated mortality was 113.8 per 100,000 inhabitants in 2010. Hospitalized patient rates remained steady between 2002 and 2012, whereas mortality decreased by 3.3% annually from 2000 to 2010. Trends in hospitalized patients and mortality differed significantly between men and women, particularly among the 45- to 55- and 65- to 74-year-old age groups, with a smaller decrease observed in women. CONCLUSION: Among men, a slight decrease in patients hospitalized for HF and a substantial reduction in mortality were observed. Among women, only a large decrease in HF mortality was observed. HF remains one of the leading causes of death and hospitalization in France, particularly in the elderly.

Comparison of the sociodemographic characteristics of the large NutriNet-Santé e-cohort with French Census data: the issue of volunteer bias revisited.

BACKGROUND: A recurring concern in traditional and in Web-based studies pertains to non-representativeness due to volunteer bias. We investigated this issue in an ongoing, large population-based e-cohort. METHODS: The sample included 122 912 individuals enrolled in the Internet-based, nutrition-focused NutriNet-Santé study between May 2009 and March 2014, with complete baseline data. Participants were recruited via recurrent multimedia campaigns and other traditional and online strategies. Individuals aged 18+ years, residing in France and having Internet access, were eligible for enrolment. Their sociodemographic characteristics were compared with the corresponding 2009 Census data via χ(2) goodness-of-fit tests. The effectiveness of statistical weighting of the e-cohort data was also explored. RESULTS: The sample exhibited marked geographical and sociodemographic diversity, including volunteers belonging to typically under-represented subgroups in traditional surveys (unemployed, immigrants, the elderly). Nonetheless, the proportions of women, relatively well-educated individuals and those who are married or cohabiting, were notably larger compared with the corresponding national figures (women: 78.0% vs 52.4%; postsecondary education: 61.5% vs 24.9%; married or cohabiting: 70.8% vs 62.0%, respectively; all p<0.0001). CONCLUSIONS: There were notable sociodemographic differences between the general French population and this general population-based e-cohort, some of which were corrected by statistical weighting. The findings bear on the potential generalisability of future investigations in the context of e-epidemiology.

Validation of a Web-based, self-administered, non-consecutive-day dietary record tool against urinary biomarkers.

New technologies are promising for the use of short-term instruments for dietary data collection; however, innovative tools should be validated against objective biomarkers. The aim of the present study was to investigate the validity of a Web-based, self-administered dietary record (DR) tool using protein, K and Na intakes against 24 h urinary biomarkers (24 h U). Of the total participants, 199 adult volunteers (104 men and 95 women, mean age 50·5 (23-83 years)) of the NutriNet-Santé Study were included in the protocol. They completed three non-consecutive-day DR and two 24 h U on the first and third DR days. Relative differences between reported (DR) and measured (24 h U) intakes were calculated from the log ratio (DR/24 h U) for protein, K and Na intakes: -14·4,+2·6 and -2·1 % for men; and -13·9, -3·7 and -8·3 % for women, respectively. The correlations between reported and true intakes were 0·61, 0·78 and 0·47 for men and 0·64, 0·42 and 0·37 for women for protein, K and Na, respectively. Attenuation factors, that represent attenuation of the true diet-disease relationship due to measurement error (a value closer to 1 indicating lower attenuation), ranged from 0·23 (Na, women) to 0·60 (K, men). We showed that the Web-based DR tool used in the NutriNet-Santé cohort study performs well in estimating protein and K intakes and fairly well in estimating Na intake. Furthermore, three non-consecutive-day DR appear to be valid for estimating usual intakes of protein and K, although caution is advised regarding the generalisability of these findings to other nutrients and general population.

Diet in 45- to 74-year-old individuals with diagnosed diabetes: comparison to counterparts without diabetes in a nationally representative survey (Etude Nationale Nutrition Santé 2006-2007).

A healthy diet has been shown to prevent diabetes complications. However, the eating habits of individuals with diabetes who are aware of their glycemic condition have been poorly studied. This study's objective was to assess the dietary behavior overall and according to dietary recommendations in adults diagnosed with diabetes compared with those of a general population of the same age (45 to 74 years) in a nationally representative survey carried out in France in 2006-2007 (Etude Nationale Nutrition Santé) (n=1,476 including 101 patients with diabetes). Trained dietitians assessed diet using three 24-hour recalls and diabetes was self-declared. After weighting and using multiple adjustments, mean food and nutrient intakes were compared according to diabetes status. Interactions with age and sex were sought. Adults with diabetes had lower intakes of sweetened foods (40 g/day vs 125 g/day), alcohol (1.45 g/day vs 1.64 g/day), energy (1,790 kcal/day vs 1,986 kcal/day), and simple sugar (63.1 g/day vs 89.8 g/day) and higher intakes of meat (126 g/day vs 109 g/day), complex carbohydrates (26.3% energy intake vs 23.6% energy intake), and vitamins B and E (628 µg/day vs 541 µg/day). In addition, 45- to 59-year-old individuals with diabetes ate more fruits and vegetables, fiber, beta carotene, folate, vitamin C, and potassium than adults of the same age who did not have diabetes. Overall, 45- to 74-year-old adults with diabetes had a higher-quality diet than individuals without diabetes. However, compared with recommendations, a healthy diet continues to represent a public health challenge in terms of preventing diabetes complications.

Participant profiles according to recruitment source in a large Web-based prospective study: experience from the Nutrinet-Santé study.

BACKGROUND: Interest in Internet-based epidemiologic research is growing given the logistic and cost advantages. Cohort recruitment to maximally diversify the sociodemographic profiles of participants, however, remains a contentious issue. OBJECTIVE: The aim of the study was to characterize the sociodemographic profiles according to the recruitment mode of adult volunteers enrolled in a Web-based cohort. METHODS: The French NutriNet-Santé Web-based cohort was launched in 2009. Recruitment is ongoing and largely relies on recurrent multimedia campaigns. One month after enrollment, participants are asked how they learned about the study (eg, general newscast or a health program on television, radio newscast, newspaper articles, Internet, personal advice, leaflet/flyers) The sociodemographic profiles of participants recruited through operative communication channels (radio, print media, Internet, advice) were compared with the profiles of those informed through television by using polytomous logistic regression. RESULTS: Among the 88,238 participants enrolled through the end of 2011, 30,401 (34.45%), 16,751 (18.98%), and 14,309 (16.22%) learned about the study from television, Internet, and radio newscasts, respectively. Sociodemographic profiles were various, with 14,541 (16.5%) aged ≥60 years, 20,166 (22.9%) aged <30 years, 27,766 (32.1%) without postsecondary education, 15,397 (19.7%) with household income <€1200/month, and 8258 (10.6%) with household income €3700/month. Compared to employed individuals, unemployed and retired participants were less likely to be informed about the study through other sources than through television (adjusted ORs 0.56-0.83, P<.001). Participants reporting up to secondary education were also less likely to have learned about the study through radio newscasts, newspaper articles, Internet, and advice than through television (adjusted ORs 0.60-0.77, P<.001). CONCLUSIONS: Television broadcasts appear to permit the recruitment of e-cohort participants with diverse sociodemographic backgrounds, including socioeconomically disadvantaged individuals who are usually difficult to reach and retain in long-term epidemiologic studies. These findings could inform future Web-based studies regarding the development of promising targeted or general population recruitment strategies.

Determinants of blood pressure treatment and control in obese people: evidence from the general population.

OBJECTIVE: We assessed hypertension prevalence, blood pressure (BP)-lowering treatment and control in obese adults compared with lean/normal-weight individuals in France. METHODS: Multistage stratified random sample of 2075 adults from the French Nutrition and Health Survey (ENNS), a cross-sectional national survey carried out in 2006-2007. BP was measured three times on the left arm using an automatic device. Weight and height were assessed using standardized methods to compute body mass index (BMI, kg/m(2)). BP-lowering drugs were self-reported. BP control was defined as SBP/DBP less than 140/90 among hypertensive individuals. RESULTS: As anticipated, mean SBP and DBP increased significantly across BMI categories (P for trend <0.0001). The age-adjusted and sex-adjusted prevalence of hypertension also increased across the same categories (15.7, 24.7 and 56.9%, respectively, P < 0.001). Among hypertensive individuals, obese participants were more likely to receive BP-lowering drugs compared with their lean/normal weight counterparts (P = 0.02). However, independently of age, smoking status and alcohol intake, obesity was associated with a 62% lower risk of BP control (OR: 0.38, 95% CI: 0.19-0.75) compared with the lean/normal-weight status. CONCLUSION: Although hypertension was much more prevalent in the obese compared with overweight and lean/normal-weight individuals, uncontrolled hypertension was also more frequent despite a higher rate of treatment. To some extent, this observation may probably be the consequence of obesity and its complex pathophysiology, more than to an inadequate therapeutic decision by clinicians.

Physical activity patterns in the French 18-74-year-old population: French Nutrition and Health Survey (Etude Nationale Nutrition Santé, ENNS) 2006-2007.

OBJECTIVE: To describe detailed physical activity and sedentary behaviour in French adults across physical activity categories. DESIGN: The French Nutrition and Health Survey (Etude Nationale Nutrition Santé, ENNS), conducted in 2006-2007, was a national cross-sectional survey based on three-stage random sampling. The International Physical Activity Questionnaire (IPAQ) was used to classify participants into three physical activity categories. Time spent in a sitting position and time spent in front of a screen were used as markers of sedentary behaviour. SETTING: France. SUBJECTS: Adults (n 2971) aged 18 to 74 years were included. RESULTS: Overall, 29·5 % of men and 23·6 % of women were classified into the high-IPAQ category, while 36·1 % of men and 37·5 % of women were in the low-IPAQ category. For each intensity level of physical activity (vigorous intensity, moderate intensity or walking), the number of active days per week decreased from the high- to the low-IPAQ category and daily duration of physical activity was longer in the high-IPAQ category than in the other two categories; 6 % of adults declared neither vigorous nor moderate nor walking activities. CONCLUSIONS: For most adults in the low-IPAQ category, an increasing number of active days per week would be sufficient to attain the moderate-IPAQ category. This should be taken into account in public health initiatives aimed at promoting physical activity.

Diet and blood pressure in 18-74-year-old adults: the French Nutrition and Health Survey (ENNS, 2006-2007).

OBJECTIVE: Dietary recommendations to reduce blood pressure (BP) have been widely disseminated. We investigated associations between dietary intake and BP in a national sample of adults living in France. METHODS: The survey included 1968 18-74-year-old participants in the French Nutrition and Health Survey (Etude Nationale Nutrition Santé), a cross-sectional national multistage sampling study. Dietary intake and SBP and DBP were assessed using three 24-h recalls and three measurements, respectively. Mean dietary intake was compared across BP categories: previously diagnosed hypertensive and among undiagnosed optimal (SBP <120  mmHg and DBP <80  mmHg), intermediate and high (SBP ≥140  mmHg and/or DBP ≥90  mmHg) BP participants. After exclusion of previously diagnosed hypertensive participants, linear regressions were also carried out between dietary intake and SBP and DBP. RESULTS: Eating habits of previously diagnosed hypertensive participants were not different from those of undiagnosed high BP participants, except higher milk consumption (P = 0.03) and lower seafood and alcohol intake (P < 0.03 and P = 0.002, respectively) in previously diagnosed hypertensive. After exclusion of them, dairy products (milk especially), fruit and vegetables, fiber and whole-grain food consumption were inversely and linearly associated with SBP (P < 0.04), whereas alcohol intake was positively associated with SBP (P < 10) and DBP (P = 0.005). Modification effect of sex was observed for saturated fatty acids intake (positive association with DPB in women) and calcium (negative association with SBP in men). CONCLUSION: Adherence to nutritional recommendations still needs to be improved in hypertensive adults even if they are aware of their condition. In the rest of the population, proper habits regarding milk, fruit and vegetables, fiber and alcohol should decrease the risk of hypertension onset.

Patterns of hypertension management in France (ENNS 2006-2007).

OBJECTIVES: The objectives of this study were to describe the hypertensive population and therapeutic management of hypertension in subjects between 18 and 74 years of age in continental France in 2006. METHODS: ENNS was a cross-sectional survey conducted in continental France in 2006-2007. Blood pressure (BP) was measured in a national sample of non-institutionalized adults aged 18-74 years and pharmacological treatment was collected by a self-questionnaire. Hypertension was defined by systolic blood pressure (SBP) ≥140 mmHg, diastolic blood pressure (DBP) ≥90 mmHg, or treatment with BP-lowering drugs. The therapeutic control of treated hypertensive patients was defined by SBP <140 mmHg and DBP <90 mmHg. RESULTS: The prevalence of hypertension was 31.0%. Half of hypertensive subjects reported taking an antihypertensive drug (50.3%) and nearly half of them were treated with a single antihypertensive pharmacological class (44.3%). Overall, among hypertensives, 25.6% had a satisfactory BP control. CONCLUSIONS: Our survey revealed a high prevalence of hypertension in continental France, with only half of the hypertensive subjects receiving pharmacological therapy and one treated out of two with BP at goal. More effective measures are needed to improve clinical management of hypertension.

Blood lead levels in the adult population living in France the French Nutrition and Health Survey (ENNS 2006-2007).

BACKGROUND: The French Nutrition and Health Survey (ENNS) was conducted in order to describe food consumption and levels of various biomarkers in the general population. In this paper, we aimed to assess the distribution of blood lead levels (BLL) in the adult population living in France. METHOD: ENNS was a cross-sectional survey carried out in the general population. Participants (18-74years of age) were sampled using a three-stage probability design stratified by geographical areas and degrees of urbanization. Collected data included biochemical samples, anthropometric measurements, socio-demographic characteristics, and environmental and occupational exposure. RESULTS: In 2006/2007, 2029 adults were included in the survey on lead. The blood lead geometric mean (GM) in the population living in France was 25.7µg/L [24.9-26.5]. The overall prevalence of elevated BLL (>100µg/L) was 1.7% [1.1-2.3%]. Levels were significantly higher in males than in females, and increased with age, smoking status and alcohol consumption. Other factors significantly associated with BLL were leisure activities, occupational category, age of housing unit, birth place and shellfish/crustacean consumption. CONCLUSION: For the first time a survey provides national estimates of BLL for the adult population in France. Comparison with results from a previous study among men aged 18-28years showed that the GM dropped more than 60% in the last 10years. The distribution of BLL in France was quite similar to that observed in other European countries.

Nutrition patterns and metabolic syndrome: a need for action in young adults (French Nutrition and Health Survey - ENNS, 2006-2007).

OBJECTIVE: The objective of this study was to investigate the relationship between adherence to French diet and physical activity recommendations and metabolic syndrome (MetS) risk. METHODS: 18-74-year-old subjects who underwent dietary assessment and health examination in the 2006-2007 French Nutrition and Health Survey (Etude Nationale Nutrition Santé, ENNS 2006-2007) were included in the analyses (n=1608). Quintiles of PNNS-GS, the score measuring adherence to French recommendations, were generated. The prevalence of overall MetS risk and separate components across quintiles of PNNS-GS was estimated by adjusted logistic regressions. Interactions were searched for between PNNS-GS and sex, age and currently used medication. RESULTS: The PNNS-GS was inversely associated with overall MetS risk in subjects not taking antidiabetic, antihypertensive or lipid-lowering medication (12.8% in the lowest quintile vs. 4.6% in the highest PNNS-GS quintile; P<0.01). This was true in 18-49-year-old subjects (10.0% vs. 1.7%, P<0.01), but not in 50-74-year-olds (23.8% vs. 11.2%; P=0.15). In 18-49-year-old adults, including those taking such medication, the HDL component was associated with PNNS-GS (22.1% vs. 7.9%; P<0.01). CONCLUSION: Improvement in diet and physical activity in line with recommendations could be effective in young adults for MetS prevention so as to decrease the risk of cardiovascular disease in France.

Compliance with French nutrition and health program recommendations is strongly associated with socioeconomic characteristics in the general adult population.

BACKGROUND: In many countries, nutrition policies such as the Programme National Nutrition Santé (PNNS), implemented in France since 2001, have been developed to prevent and reduce the risk of chronic disease. However, the way in which such programs might benefit persons having different socioeconomic characteristics is unknown. The French nutrition and health survey (Etude Nationale Nutrition Santé [ENNS]) represented an opportunity to address this issue. OBJECTIVE: To describe compliance with PNNS recommendations in the general population and to investigate the relationship between social, economic, and educational characteristics and poor compliance with French nutrition recommendations. DESIGN: A national cross-sectional multistage sampling survey. Food intake was estimated through three 24-hour recalls. Adherence to French nutrition recommendations was estimated using the PNNS guideline score (15 possible points). PARTICIPANTS: Two thousand five hundred seventy-seven adults aged 18 to 74 years living in France in 2006-2007 were included in these analyses. STATISTICAL ANALYSIS: All analyses were carried out in men and women separately. Sex-specific quartiles of score were estimated. Multiple logistic models were used to identify socioeconomic characteristics (ie, age, marital status, occupational status, education level, and holiday trip in the past 12 months) associated with poor compliance with recommendations (first PNNS guideline score quartile vs three other quartiles), estimating odds ratios (ORs), and their 95% confidence intervals (CIs). RESULTS: The mean PNNS guideline score was 7.67+/-0.17 in men and 8.55+/-0.12 in women. In both sex groups, a difference of approximately four attained recommendations (out of 13 maximum) was observed between the lowest and highest quartiles. In multivariate models, being in the first PNNS guideline score quartile was significantly associated with lower age and lower occupational status for both sexes. Moreover, women living without a partner were at higher risk of poor compliance with recommendations (adjusted OR 1.43; 95% CI 1.01 to 2.04, vs women living with a partner), as were men not having taken a holiday trip during the past 12 months (adjusted OR 1.78, 95% CI 1.05 to 3.02, vs at least one holiday trip). CONCLUSIONS: Compliance with nutrition recommendations can be improved despite several years of public health interventions carried out by the PNNS. Identification of characteristics associated with poor compliance should help to target future public health measures.

Association of socioeconomic status with overall overweight and central obesity in men and women: the French Nutrition and Health Survey 2006.

BACKGROUND: Identification of subpopulations at high risk of overweight and obesity is crucial for prevention and management of obesity in different socioeconomic status (SES) categories. The objective of the study was to describe disparities in the prevalence of overweight and obesity across socioeconomic status (SES) groups in 18-74 year-old French adults. METHODS: Analyses were based on a multistage stratified random sample of non-institutionalized adults aged 18-74-years-old from the French Nutrition and Health Survey (ENNS), a cross-sectional national survey carried out in 2006/2007. Collected data included measured anthropometry (weight, height and waist circumference (WC)), demographic and SES data (occupation, education and frequency of holiday trips as a marker of family income). SES factors associated with overweight (BMI > or = 25) and central obesity (WC above gender-specific references) were identified using multiple logistic regression. RESULTS: Almost half (49.3%) of French adults were overweight or obese and 16.9% were obese. In men, the risk of overall overweight or obesity was associated with occupation (p < 0.05), whereas the risk of central obesity was independently associated with occupation (p < 0.05) and frequency of holiday trips (p < 0.01). In women, both overall and central overweight and obesity were independently associated with educational level (respectively p < 10(-3) and p < 10(-3)) and frequency of holiday trips (respectively p < 0.05 and p < 10-3). CONCLUSION: The prevalence of overweight and obesity was found to be similar to that of several neighbouring western European countries, and lower than the UK and eastern Europe. Risk of being overweight or obese varied across SES groups both in men and women, but associations were different between men and women, indicating differing determinants.
