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. 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. 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. In this pilot study, food insufficiency was significantly decreased in families receiving vouchers for fruits and vegetables over a one-year period.

水果和蔬菜券对巴黎郊区贫困家庭粮食不安全的影响


即使在发达国家，营养方面的社会不平等也导致大量家庭陷入粮食不安全的困境。我们的目的是评估水果和蔬菜券对巴黎郊区弱势家庭粮食安全的影响。我们采用了事前事后评估设计。在随机分配的干预措施之前和之后，家庭回答了有关食品消费和食品安全状况的面对面调查问卷。干预组的家庭收到了一年内专门购买水果和蔬菜的代金券。在研究期间，干预组和对照组都受益于营养师举办的研讨会的营养教育。家庭粮食安全模块（HFSM）用于评估纳入家庭的粮食安全状况。粮食不足指标（FSI）用于评估纳入和后续行动中的粮食安全。使用 McNemar 检验评估两组 FSI 的演变。 2015年5月至2016年5月期间纳入的91个家庭中，有64个家庭完成了事后评估问卷。纳入调查时，68.3% 的家庭面临粮食不安全，78.1% 的家庭面临粮食不足。没有发现食物消费与粮食安全状况之间存在关联。一年随访后，干预组食物不足发生率显着下降（61.8%，p 值 = 0.03），而对照组则没有变化。在这项试点研究中，在一年内获得水果和蔬菜代金券的家庭中，粮食不足的情况显着减少。 NCT02461238，2015 年 6 月 3 日注册 – 回顾性注册，https://clinicaltrials.gov/ct2/show/NCT02461238
