To evaluate the provision of free school meals in Trinidad and Tobago in relation to children's social and nutritional status.
Cross-sectional survey of a nationally representative sample of 66 government schools, including children in the admissions classes (aged 4 to 7 years) and classes for 'rising nines' (aged 7-10 years). Data included questionnaire details of free school meals and children's social background, and measurements of children's heights, weights and skinfold thicknesses.
Of 6731 eligible children, data were analysed for 5688 (85%). There were 2386 (42%) children receiving free meals provided at school. At different schools the proportion of all children receiving free meals ranged from 20% to 100%, Receipt of free meals was associated with larger family size (one child, 32% received free meals; > or =6 children, 63%), lower paternal educational attainment (primary, 52% free; university, 30%), father's employment (employed, 39% free meals; unemployed >12 months, 59%) as well as maternal education and employment and household amenities. After adjusting for age, sex and ethnic group, children who received free meals were shorter (mean difference in height standard deviation score (SDS) -0.12, 95% confidence interval (CI) -0.17 to -0.06), lighter (body mass index SDS -0.21, -0.28 to -0.14) and thinner (subscapular skinfold SDS -0.13, -0.18 to -0.09).
Free school meals were widely available, with some targeting of provision to children with less favourable social and nutritional status. Greater universality would reduce inequity, but more stringent targeting and reduction of school-level variation would increase efficiency.
评估特立尼达和多巴哥免费学校餐供应情况与儿童社会及营养状况的关系。
对66所政府学校的全国代表性样本进行横断面调查,样本包括入学班级(4至7岁)和“快九岁”班级(7至10岁)的儿童。数据包括免费学校餐的问卷详情、儿童社会背景,以及儿童身高、体重和皮褶厚度的测量值。
在6731名符合条件的儿童中,对5688名(85%)进行了数据分析。有2386名(42%)儿童在学校接受免费餐。在不同学校,所有儿童中接受免费餐的比例从20%到100%不等。接受免费餐与家庭规模较大(一个孩子,32%接受免费餐;≥6个孩子,63%)、父亲教育程度较低(小学,52%免费;大学,30%)、父亲就业情况(就业,39%接受免费餐;失业超过12个月,59%)以及母亲教育程度、就业情况和家庭设施有关。在对年龄、性别和种族进行调整后,接受免费餐的儿童更矮(身高标准差得分(SDS)平均差异为-0.12,95%置信区间(CI)为-0.17至-0.06)、更轻(体重指数SDS为-0.21,-0.28至-0.14)且更瘦(肩胛下皮褶SDS为-0.13,-0.18至-0.09)。
免费学校餐广泛供应,部分针对社会和营养状况较差的儿童。提高普及程度将减少不平等,但更严格的目标定位和减少学校层面的差异将提高效率。
