乌干达维生素A缺乏症（VAD）持续存在，食用富含β-胡萝卜素的橙子甘薯（OSP）可能有助于缓解这一问题。这些方案在第二年的投入有所不同，一个方案的投入更密集（IP），另一个方案的投入减少（RP）。一项随机、对照有效性研究比较了IP和RP与对照组对6- 3 - 5个月（n = 265）和3-5岁（n = 578）儿童以及女性（n = 573）OSP和维生素A摄入量的影响，和（与对照组相比，3至5岁儿童（n = 891）和妇女（n = 939）的维生素A状况，血清视黄醇30个百分点）和妇女（>25个百分点）（P < 0.01），儿童（P = 0.75）或妇女（P = 0.17）的IP和RP组之间没有差异。血清视黄醇水平下降了9.5个百分点，
Vitamin A deficiency (VAD) persists in Uganda and the consumption of beta-carotenerich orange sweet potato (OSP) may help to alleviate it. Two large-scale, 2-y intervention programs were implemented among Ugandan farmer households to promote the production and consumption of OSP. The programs differed in their inputs during year 2, with one being more intensive (IP) and the other being reduced (RP). A randomized, controlled effectiveness study compared the impact of the IP and RP with a control on OSP and vitamin A intakes among children aged 6-35 mo (n = 265) and 3-5 y (n = 578), and women (n = 573), and (P compared with control on vitamin A status of 3- to 5-y-old children (n = 891) and women (n = 939) with serum retinol 30 percentage points) and women (>25 percentage points) (P < 0.01), with no differences between the IP and RP groups of children (P = 0.75) or women (P = 0.17). There was a 9.5 percentage point reduction in prevalence of serum retinol
