人们越来越担心食品或现金转移计划可能会导致成年人超重和肥胖。我们研究了墨西哥的 Apoyo Alimentario 计划 (PAL) 对妇女体重的影响，该计划为非常贫困的农村家庭提供现金或实物转移。墨西哥南部 208 个农村社区的随机样本被随机分配到 4 组中的一组：有或没有健康和营养教育的食品篮、有教育的现金或对照组。使用双重差分模型评估了 3010 名女性的队列对女性体重的影响。我们比较了食品篮和现金组之间的影响，并评估了该影响是否会因基线时女性的 BM I 状态而改变。相对于对照组，该计划增加了食品篮中女性的体重（550 +/- 210 克；P = 0.004）和现金组（420 +/- 230 克；P = 0.032）；这相当于 23 个月内与对照组相比，体重分别增加了 70% 和 53%。对已经肥胖的女性影响最大：食品篮组减重 980 +/- 290 克（P = 0.001），现金组减重 670 +/- 320 克（P = 0.019）。对于计划前 BMI 在 25 至 30 kg/m(2) 之间的女性，影响略有显着：分别为 490 310 g (P = 0.055) 和 540 +/- 360 g (P = 0.067)。没有发现该计划对具有 BMI 的女性产生影响
There is a growing concern that food or cash transfer programs may contribute to overweight and obesity in adults. We studied the impact of Mexico's Programs de Apoyo Alimentario (PAL), which provided very poor rural households with cash or in-kind transfers, on women's body weight. A random sample of 208 rural communities in southern Mexico was randomly assigned to 1 of 4 groups: food basket with or without health and nutrition education, cash with education, or control. The impact on women's weight was estimated in a cohort of 3010 women using a difference-in-difference model. We compared the impact between the food basket and cash groups and evaluated whether the impact was modified by women's BM I status at baseline. With respect to the control group, the program increased women's weight in the food basket (550 +/- 210 g; P = 0.004) and the cash group (420 +/- 230 g; P = 0.032); this was equivalent to 70 and 53% increases in weight gain, respectively, over that observed in the control group in a 23-mo time period. The greatest impact was found in already obese women: 980 +/- 290 g in the food basket group (P = 0.001) and 670 +/- 320 g in the cash group (P = 0.019). impact was marginally significant in women with a preprogram BMI between 25 and 30 kg/m(2): 490 310 g (P = 0.055) and 540 +/- 360 g (P = 0.067), respectively. No program impact was found in women with a BMI
