Abstract
BACKGROUND Physical activity (PA) is a key factor for facing the increasing prevalence of obesity and overweight, and should be part of every public health programs. In this context, a community-based public health program promoting PA was developed in a low-income neighborhood of the city of Saint-Denis (France). METHODS This work aimed at assessing the effectiveness of a 2-year PA promotion program. A quasi-experimental study was carried out using a pre/post design, with an assessment before (2013) and after (2015) the program. The interviewees were selected using a stratified random cluster sampling. The primary outcome was the proportion of participants practicing sufficient PA (WHO guidelines), and was measured using the RPAQ questionnaire. External interventions (on both neighborhood environment and inhabitants) were listed. RESULTS We collected 199 questionnaires at baseline and 217 in 2015. There was a majority of women in both samples: 64.3 % in 2013 and 58.2 % in 2015. The average age of participants was 38.1 years (+/-1.1) and 40.6 (+/-1.1) respectively. The proportion of people practicing sufficient PA was modified from 48.1 % in 2013 to 63.5 % in 2015 (p = 0.001). This was mainly driven by women whose level of PA, increased from 40.3 % to 60.3 % (p = 0.002), reaching the average national French estimation of PA level among adults (63.5 %). CONCLUSIONS This work showed a significant increase of the proportion of people practicing PA in a disadvantaged neighborhood where a community-based program promoting PA was developed. Simultaneous external interventions contributed to the results, showing the necessity of synergic interventions to reach efficiency.

Abstract
BACKGROUND Metabolic syndrome (MetS), comprising high waist circumference, blood pressure, glycemia, and triglycerides, and lower HDL cholesterol could in part be prevented by adequate nutrition. Nutrient profiling systems could be useful public health tools to help consumers make healthier food choices. An individual dietary index (DI) based on nutrient profiling of foods consumed could characterize dietary patterns in relation to the onset of MetS. OBJECTIVE The objective of this study was to prospectively investigate the association between the Food Standards Agency (FSA) Nutrient Profiling System (NPS) DI and the onset of MetS in a middle-aged French cohort. METHODS Participants from the SUpplémentation en VItamines et Minéraux AntioXydants cohort (SU.VI.MAX, n = 3741) were included in the present study. The FSA NPS DI was computed by using dietary data from 24 h records at inclusion. MetS was identified at baseline and at year 13 of follow-up with the use of self-reported medication, data from clinical investigations, and biological measurements. A prospective association between the FSA NPS DI (in quartiles and continuous) and the onset of MetS was investigated by using logistic regression. RESULTS Poorer diets identified with the use of the FSA NPS DI were significantly associated with a higher risk of developing MetS (OR for poorer vs. healthier FSA NPS DI 1.43; 95% CI: 1.08, 1.89; P-trend across quartiles = 0.02). The FSA NPS DI was significantly associated with the systolic blood pressure (SBP) and diastolic blood pressure (DBP) components of MetS (difference between healthier vs. poorer FSA NPS DI 2.16 mm Hg for SBP and 1.5 mm Hg for DBP, P-trend across quartiles = 0.02). CONCLUSION The FSA NPS DI was prospectively associated with the onset of MetS in a middle-aged French population. The application of NPSs in public health initiatives may help the population make healthier food choices, which might reduce the risk of developing MetS.
