BackgroundNutrition-related chronic diseases such as cardiovascular diseases and cancer are of multiple origin, and may be due to genetic, biologic, behavioural and environmental factors. In order to detangle the specific role of nutritional factors, very large population sample cohort studies comprising precisely measured dietary intake and all necessary information for accurately assessing potential confounding factors are needed. Widespread use of internet is an opportunity to gradually collect huge amounts of data from a large sample of volunteers that can be automatically verified and processed. The objectives of the NutriNet-Santé study are: 1) to investigate the relationship between nutrition (nutrients, foods, dietary patterns, physical activity), mortality and health outcomes; and 2) to examine the determinants of dietary patterns and nutritional status (sociological, economic, cultural, biological, cognitive, perceptions, preferences, etc.), using a web-based approach.Methods/designOur web-based prospective cohort study is being conducted for a scheduled follow-up of 10 years. Using a dedicated web site, recruitment will be carried out for 5 years so as to register 500 000 volunteers aged ≥ 18 years among whom 60% are expected to be included (having complete baseline data) and followed-up for at least 5 years for 240 000 participants. Questionnaires administered via internet at baseline and each year thereafter will assess socio-demographic and lifestyle characteristics, anthropometry, health status, physical activity and diet. Surveillance of health events will be implemented via questionnaires on hospitalisation and use of medication, and linkage with a national database on vital statistics. Biochemical samples and clinical examination will be collected in a subsample of volunteers.DiscussionSelf-administered data collection using internet as a complement to collection of biological data will enable identifying nutrition-related risks and protective factors, thereby more clearly elucidating determinants of nutritional status and their interactions. These are necessary steps for further refining nutritional recommendations aimed at improving the health status of populations.

BackgroundIdentification 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.MethodsAnalyses 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 ≥ 25) and central obesity (WC above gender-specific references) were identified using multiple logistic regression.ResultsAlmost 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).ConclusionThe 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.

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.

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 < 10−3) 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.

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.

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.

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 studys 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.

OBJECTIVES To describe Blood Pressure (BP) according to the time spent viewing television and examine whether the associations between television viewing and systolic and diastolic BP differed depending on sex, age and BMI. DESIGN The French health and nutrition survey (ENNS) was conducted in 2006-2007 on a multistage stratified random sample of 18-74-year-old adults. METHODS Systolic (SBP) and diastolic BP (DBP) were assessed using three measurements. Among subjects without BP-lowering drugs and lifestyle measures, adjusted means of SBP and DBP were estimated for each television viewing category (<3h and ≥3h). RESULTS Among 2050 ENNS participants, 81.2% declared neither drug medication nor lifestyle change to lower BP. In women without BP-lowering measure, viewing television 3h/day or more increased significantly SBP and DBP adjusted means (+2mmHg) compared to women who spent less than 3h/day in front of the television. These associations were stronger in obese or 35-54-year-old women. In men, no relationship between DBP and television-viewing has been observed. Though, SBP was positively associated with television-viewing in non-overweight, 18-29 or 55-74 year-old men. CONCLUSIONS These results show that the association between television viewing duration and BP must be evaluated differently between gender, age group and BMI category.

Objective: To describe blood pressure (BP) according to physical activity in 18–74-year-old adults without BP-lowering measures. Design and Method: The French nutrition and health survey (ENNS), a national cross-sectional study, was conducted in 2006–2007. Using the short form of the International Physical Activity Questionnaire (IPAQ), the declared amount of total physical activity (including leisure time-, domestic-, work- and transport-related physical activities) was collected. Systolic and diastolic BP (SBP/DBP) were measured using the same automatic device (OMRON® M5–1) and standardized protocols. Using linear regression models, adjustment was performed on confounding factors. Adjusted BP means were estimated in each IPAQ category. Due to significant interactions, analyses were stratified by gender, body mass index (BMI) classes and age groups. Results: Among 2,058 ENNS participants, analyses were carried out on 1,650 adults who declared no BP-lowering measures (drug, diet or increasing physical activity). In men, adjusted SBP/DBP means were 125.5/78.1, 125.8/78.4 and 126.4/77.9 mmHg in the low-, moderate- and high-IPAQ categories, respectively. In women, means were 116.4/75.4, 114.1/74.5 and 116.5/75.1 mmHg, respectively. In both men and women, differences across IPAQ categories were not statistically significant. After stratification by gender and BMI classes, there was no association between BP and physical activity. However, in obese women, adjusted SBP mean was higher in the high-IPAQ category than in the moderate (133 ± 4.1 vs 120 ± 2.1 mmHg, respectively, p = 0.008), but the linear trend between continuous variables (BP and the amount of physical activity) was not significant. After stratification on gender and age groups, the sole significant trend was observed in 18–29-year-old men, for whom DBP was negatively associated with the amount of physical activity (p = 0.002). Conclusion: These results support that, after adjustment for confounding factors and stratified analyses, the amount of total physical activity (declared using the IPAQ questionnaire and not specifically limited to physical training) has no proper effect on the level of BP in 18–74-year-old adults without BP-lowering measures, except to reduce DBP in young men.
