Background: Social inequalities in nutrition lead a high number of families to struggle with food insecurity, even in developed countries. We aimed to assess the impact of fruits and vegetables vouchers on food security among disadvantaged households from a Paris suburb. Methods: We used a pre-post assessment design. Families answered face-to-face questionnaires on food consumption and food security status before and after a randomly assigned intervention. Households in the intervention group received vouchers to buy exclusively fruits and vegetables over one year. Both intervention and control groups benefitted from nutritional education through workshops performed by dieticians during the study period. The Household Food Security Module (HFSM) was used to assess food security status of households at inclusion. Food Insufficiency Indicator (FSI) was used to assess food security at inclusion and follow-up. Evolution of FSI on both groups was evaluated using McNemar test. Results: Among the 91 families included between May 2015 and May 2016, 64 completed the post assessment questionnaire. At inclusion, 68.3% of families were experiencing food insecurity and 78.1% were experiencing food insufficiency. No association was found between food consumptions and food security status. After one-year follow-up, the prevalence of food insufficiency was significantly decreased in the intervention group (61.8%, with p value = 0.03), and unchanged in the control group. Conclusion: In this pilot study, food insufficiency was significantly decreased in families receiving vouchers for fruits and vegetables over a one-year period.
BackgroundFruits and Vegetables (FV) consumption is considered a marker of social inequalities in health since it is considerably decreased in disadvantaged populations. The main objective of this trial was to evaluate the impact of vouchers for FV purchase on the consumption of FV among children living in disadvantaged families in a French urban district.MethodsThe FLAM study was a controlled randomized intervention trial, performed in Saint-Denis (North suburbs of Paris). The study group (intervention or control) was randomly attributed to parent-child pairs at inclusion. The intervention group received vouchers exchangeable for FV over a 1 year period. Nutritional education through workshops was available for both groups. FV consumption was assessed through face-to-face food frequency questionnaires. Participants who reported eating less than 3.5 FV per day were considered low FV consumers.ResultsA total of 92 parent-child pairs were included, in which 45 were allocated to the intervention group and 47 to the control group. Amongst them, 64 completed the final follow-up questionnaire (30% lost to follow-up). After one year, the proportion of low FV consumers in children was significantly lower in the intervention group (29.4%) compared to the control group (66.7%, p = 0.005). Overall, 82% of the vouchers were used by the families.ConclusionsThis study found a decreased proportion of small consumers in children after 1 year of distribution of FV vouchers compared to the control group. FV vouchers could be an effective lever to increase FV consumption among children from disadvantaged households.Trial registrationClinicalTrials.gov identifier no. NCT02461238.
BackgroundPhysical 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).MethodsThis 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.ResultsWe 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 %).ConclusionsThis 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.
BackgroundThe FLAM study was set up in order to assess the effectiveness of FV vouchers allowed to low-income households, on their FV consumption. The aim of the present study was to investigate issues associated with conducting interventional trials in disadvantaged populations using the FLAM study as an example of reaching target populations and recruitment difficulties.MethodsFamilies were recruited in Saint-Denis city (North Paris suburb), via social and municipal structures. Main interest variables in the study (food consumptions) were collected using face-to-face food interviews, either at home or municipal facilities. A qualitative analysis was performed among people who refused to participate in order to understand the barriers to participation.ResultsA total of 95 parents-child pairs were included from May 2015 to May 2016. The families were mostly in precarious situation (63.3%), and most of parents were unemployed (71.3%). Almost the two third of children and 79.4% of parents were small consumers of FV (less than 3.5 servings per day). Several reasons for non-participation were reported including time constraints, understanding and mistrust issues.ConclusionsThough using facilitating strategies, we recruited fewer participants than expected. The population finally included was mainly made of precarious families with a low consumption of FV. These results highlight the importance of identifying effective facilitating strategies to improve recruitment in disadvantaged populations.Trial registrationClinicalTrial.gov no.
