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

<p>Abstract</p> <p>Background</p> <p>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.</p> <p>Methods</p> <p>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 ≥ 25) and central obesity (WC above gender-specific references) were identified using multiple logistic regression.</p> <p>Results</p> <p>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^-3and p < 10^-3) and frequency of holiday trips (respectively p < 0.05 and p < 10^-3).</p> <p>Conclusion</p> <p>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.</p

The Treatment In Morning versus Evening (TIME) study:Analysis of recruitment, follow-up and retention rates post-recruitment

Abstract Background The use of information technology (IT) is now the preferred method of capturing and storing clinical research data. The Treatment In Morning versus Evening (TIME) study predominantly uses electronic data capture and IT to compare morning dosing of hypertensive medication against evening dosing. Registration, consent, participant demographics and follow-up data are all captured via the study website. The aim of this article is to assess the success of the TIME methodology compared with similar studies. Methods To assess the TIME study, published literature on similar clinical trials was reviewed and compared against TIME recruitment, follow-up and email interaction data. Results The TIME website registered 31,695 individuals, 21,116 of whom were randomised. Recruitment cost per randomised participant varied by strategy: £17.40 by GP practice, £3.08 by UK Biobank and £58.82 for GoShare. Twelve-month follow-up retention rates were 96%. A total of 1089 participants have withdrawn from their assigned time of dosing, 2% of whom have declined follow-up by record linkage or further contact. When the TIME data are compared with similar study data, study recruitment is very successful. However, TIME suffers difficulties with participant follow-up and withdrawal rates similar to those of conventional studies. Conclusions The TIME study has been successful in recruitment. Follow-up, retention rates and withdrawal rates are all acceptable, but ongoing work is required to ensure participants remain engaged with the study. Various recruitment strategies are necessary, and all viable options should be encouraged to maintain participant engagement throughout the life of studies using IT

Plus de voyages, plus de kilomètres quotidiens : une tendance à l'homogénéisation des comportements de mobilité des Français, sauf entre ville et campagne

L'enquête nationale Transports et déplacements (ENTD) donne un panorama général et cohérent de l'ensemble des aspects de la mobilité des Français. En effet, elle permet de décrire en même temps une mobilité locale quotidienne et des déplacements à longue distance moins fréquents. La stabilité de la mobilité locale (3,15 déplacements par personne en 2008) et la légère augmentation du temps consacré aux déplacements (+ 1,6 minute de 1994 à 2008) masquent néanmoins certaines évolutions. Les distances quotidiennes parcourues sont toujours en augmentation (+ 2,1 kilomètres de 1994 à 2008) et les personnes âgées plus mobiles qu'en 1994. L'augmentation de la mobilité à longue distance est portée par la croissance de la population et la hausse du nombre moyen de voyages par individu (+ 0,9 voyage de 1994 à 2008). La distance parcourue lors d'un voyage reste stable (944 kilomètres en 2008). En mobilité locale comme à longue distance, la voiture reste le mode de transport dominant
