To determine whether a cash-for-work programme during the annual food insecurity period in Bangladesh improved nutritional status in poor rural women and children.
The panel study involved a random sample of 895 households from over 50,000 enrolled in a cash-for-work programme between September and December 2007 and 921 similar control households. The height, weight and mid-upper arm circumference of one woman and child aged less than 5 years from each household were measured at baseline and at the end of the study (mean time: 10 weeks). Women reported 7-day household food expenditure and consumption on both occasions. Changes in parameters were compared between the two groups.
At baseline, no significant difference existed between the groups. By the study end, the difference in mean mid-upper arm circumference between women in the intervention and control groups had widened by 2.29 mm and the difference in mean weight, by 0.88 kg. Among children, the difference in means between the two groups had also widened in favour of the intervention group for: height (0.08 cm; P<0.05), weight (0.22 kg; P<0.001), mid-upper arm circumference (1.41 mm; P<0.001) and z-scores for height-for-age (0.02; P<0.001), weight-for-age (0.17; P<0.001), weight-for-height (0.23; P<0.001) and mid-upper arm circumference (0.12; P<0.001). Intervention households spent more on food and consumed more protein-rich food at the end of the study.
The cash-for-work programme led to greater household food expenditure and consumption and women's and children's nutritional status improved.
在孟加拉国每年粮食无保障期间,评估以工换粮方案是否改善了贫困农村妇女和儿童的营养状况。
本面板研究涉及在 2007 年 9 月至 12 月期间参加以工换粮方案的 5 万多登记家庭中,随机抽取 895 户家庭,以及 921 户类似的对照家庭。在基线和研究结束时(平均时间:10 周),测量每户的 1 名妇女和 1 名 5 岁以下儿童的身高、体重和中上臂围。妇女在两次调查时都报告了 7 天家庭食物支出和消费情况。两组之间的参数变化进行了比较。
在基线时,两组之间没有显著差异。在研究结束时,干预组和对照组妇女的平均中上臂围之间的差异扩大了 2.29 毫米,体重差异扩大了 0.88 公斤。在儿童中,两组之间的平均值差异也朝着有利于干预组的方向扩大:身高(0.08 厘米;P<0.05)、体重(0.22 公斤;P<0.001)、中上臂围(1.41 毫米;P<0.001)和身高年龄 Z 分数(0.02;P<0.001)、体重年龄 Z 分数(0.17;P<0.001)、体重身高 Z 分数(0.23;P<0.001)和中上臂围 Z 分数(0.12;P<0.001)。干预家庭在研究结束时在食物上的支出更多,并且消费了更多富含蛋白质的食物。
以工换粮方案导致家庭食物支出和消费增加,妇女和儿童的营养状况得到改善。
