One of the primary objectives of Brazil's conditional cash transfer program, Bolsa Família, is to break the intergenerational transmission of poverty by improving human capital via conditionalities. In this study, we hypothesized that health indicators of Bolsa Família participants would be comparable to those of other local children who were nonparticipants after two years of follow-up in the city of Acrelândia, Acre state, Western Brazilian Amazon.
Data from a population-based longitudinal study were analyzed to examine school enrollment, vaccination coverage, height and body mass index for age z-scores, and biomarkers of micronutrient deficiencies (iron and vitamin A) between Bolsa Família participants (n = 325) and nonparticipants (n = 738).
Out of 1063 children 10 years and younger included in the 2007 baseline survey, 805 had anthropometric measurements and 402 had biochemical indicators in the 2009 follow-up survey. Prevalence rate ratio (PRR) for non-enrollment in school at 4 years of age was 0.58 (95%CI: 0.34-1.02) when comparing Bolsa Família participants with nonparticipants. No difference was found for vaccination coverage, which was insufficient for most vaccine-preventable diseases. Bolsa Família participants were less likely to show a positive change in body mass index for age z-scores compared with nonparticipants (PRR = 0.81, 95%CI: 0.70-0.95), while a positive change in height for age z-scores was similar in the groups. No differences in micronutrient deficiencies were found between groups after 2 years.
Early school enrollment and consistent nutritional indicators between Bolsa Família participants and nonparticipants suggest Bolsa Família was facilitating similarities between groups over time.
巴西有条件现金转移计划“家庭补助金计划”(Bolsa Família)的主要目标之一是通过条件要求来改善人力资本,从而打破贫困的代际传递。在这项研究中,我们假设在巴西亚马孙西部阿克里州阿克里兰迪亚市进行了两年的随访后,“家庭补助金计划”参与者的健康指标将与其他当地非参与者的健康指标相当。
对一项基于人群的纵向研究的数据进行了分析,以检查学校入学率、疫苗接种覆盖率、身高和年龄别体重 z 评分、以及微量营养素缺乏的生物标志物(铁和维生素 A)在“家庭补助金计划”参与者(n=325)和非参与者(n=738)之间的差异。
在 2007 年基线调查中,1063 名 10 岁及以下的儿童中,有 805 人在 2009 年随访调查中进行了人体测量,有 402 人进行了生化指标检测。在比较 4 岁时未入学的情况时,“家庭补助金计划”参与者的非入学率比值比(PRR)为 0.58(95%可信区间:0.34-1.02)。疫苗接种覆盖率没有差异,大多数疫苗可预防疾病的接种率都不足。与非参与者相比,“家庭补助金计划”参与者的体重指数年龄 z 评分更不可能出现积极变化(PRR=0.81,95%可信区间:0.70-0.95),而两组的身高年龄 z 评分变化相似。两组在 2 年后的微量营养素缺乏方面没有差异。
早期入学和“家庭补助金计划”参与者与非参与者之间持续的营养指标相似,表明“家庭补助金计划”随着时间的推移促进了两组之间的趋同。
