Anemia is a severe public health problem in the Lao People's Democratic Republic (PDR). Consequently, a new control strategy to reduce the burden of anemia has been introduced for preschool children (aged 6-52 months). The objective of this study was to assess the current prevalence of anemia and related factors in preschool children in southern rural Lao PDR. A population-based cross-sectional study was carried out in six communities in Songkhone district, Savannakheth province, in February 2009. As a result, the prevalence of anemia was found to be 48.9% (95% confidence interval (CI), 43.5-54.3), although most cases were mild. A multiple logistic regression analysis indicated that there was no protective effect of breastfeeding against anemia. The anemia prevalence was higher in 1) children aged 6-23 months (Odds Ratio (OR) = 1.73, 95% CI, 1.02-2.90) than in older children, 2) children in large families (6 or more members) (OR = 1.96, 95% CI, 1.17-3.29), and 3) children in three remote villages with relatively difficult access to markets (OR = 3.01, 95% CI, 1.25-7.47).In Lao PDR, improvement of food practices and home-fortified food supplementation interventions are essential. High-risk groups should be targeted and a long-term health education program that aims to modify food habits implemented. Furthermore, in settings where iron deficiency is not the only cause of anemia, combining an iron supplement with other measures is necessary.
贫血在老挝人民民主共和国是一个严重的公共卫生问题。因此,该国针对学龄前儿童(6至52个月龄)引入了一项减轻贫血负担的新控制策略。本研究的目的是评估老挝人民民主共和国南部农村地区学龄前儿童贫血的当前患病率及相关因素。2009年2月,在沙湾拿吉省宋孔县的六个社区开展了一项基于人群的横断面研究。结果发现,贫血患病率为48.9%(95%置信区间(CI),43.5 - 54.3),不过大多数病例为轻度。多因素logistic回归分析表明,母乳喂养对贫血无保护作用。贫血患病率在以下情况较高:1)6至23个月龄的儿童(优势比(OR) = 1.73,95% CI,1.02 - 2.90)高于大龄儿童;2)大家庭(6名或更多成员)中的儿童(OR = 1.96,95% CI,1.17 - 3.29);3)位于三个偏远村庄且进入市场相对困难的儿童(OR = 3.01,95% CI,1.25 - 7.47)。在老挝人民民主共和国,改善饮食习惯和进行家庭强化食品补充干预至关重要。应针对高危人群,并实施旨在改变饮食习惯的长期健康教育项目。此外,在缺铁并非贫血唯一病因的情况下,有必要将铁补充剂与其他措施相结合。
