摘要: Background: It is unclear what effects a conditional cash transfer (CCT) program would have on child anthropometry, language development, or school achievement in the context of nutrition transition experienced by many low- and middle-income countries. Objective: We estimated association participation Perus Juntos CCT with among children aged 7–8 y. Methods: used data from Young Lives cohort study, born between 2001 2002. associations height-for-age z score (HAZ), body mass index–for–age (BAZ), stunting, overweight at age y separately for participating $ 2y( n = 169) <2 (n 188). then associationswithreceptivevocabularyand gradeachievementamongchildrenwhohadbeenassessedatage4–6ybeforeenrollmentin 243). identified control subjects using propensity matching conducted difference-in-differences comparisons. Results: was associated increases HAZ boys $2 [average effect treatment treated (ATT): 0.43; 95% CI: 0.09, 0.77;P 0.01] (ATT: 0.52; 0.23, 0.80; P < 0.01). Among girls y, BAZ declined –0.60; –1.00, –0.21; 0.01) as did prevalence –22.0 percentage points; –42.5, –2.7 0.03). observed no significant receptive vocabulary grade attainment. Conclusions: Peru better linear growth decreased girls, highlighting that large-scale poverty-alleviation intervention may influence anthropometric outcomes transition.
