A randomized community trial investigated the impact of vitamin A supplementation on symptoms of respiratory and enteric infections among Indonesian children aged 1 to 5 years. A sample of 450 villages had been randomized into 229 villages that received vitamin A distribution and 221 that were observed as controls. The prevalence rates of cough, fever, and diarrhea were reduced in the treatment villages compared with the control villages by 8%, 5%, and 11%, respectively, but the reduction was not statistically significant. These results indicate that vitamin A supplements did not produce a substantial reduction in these symptoms, in spite of a reported reduction in all-cause mortality.
一项随机社区试验研究了补充维生素A对印度尼西亚1至5岁儿童呼吸道和肠道感染症状的影响。450个村庄的样本被随机分为229个接受维生素A分发的村庄和221个作为对照观察的村庄。与对照村庄相比，治疗村庄咳嗽、发烧和腹泻的患病率分别降低了8%、5%和11%，但这种降低没有统计学意义。这些结果表明，尽管有报告称补充维生素A可降低全因死亡率，但维生素A补充剂并未使这些症状大幅减少。
