In South Asia, childhood undernutrition persists while overweight is increasing. Internationally recommended infant and young child feeding (IYCF) practices promote healthy nutritional status; however, little is known about IYCF in Bhutan, investigated here using 2015 National Nutrition Survey data. WHO/UNICEF IYCF indicators, anthropometry and household socio-economic status were available for 441 children <24 months. Stunting, wasting, and underweight prevalence (<-2Z length-for-age [LAZ], weight-for-age, [WAZ] and weight-for-length [WLZ], respectively) were 15%, 9%, and 5%, respectively, whereas overweight (WLZ >2) prevalence was 6%. In survey-design-adjusted analyses, 52% of mothers of 0- to 5-month olds reported exclusive breastfeeding (EBF), with EBF less common for girls than boys (OR: 0.2 [95% CI: 0.1-0.9]). Although 61% of children were breastfed at 2 years and 75% of children >6 months met a minimum daily meal frequency, only 18% of children 6-23 months met minimum dietary diversity. IYCF was unassociated with risk of stunting, wasting, or underweight, possibly due to relatively low prevalence of anthropometric failure and small sample size. However, currently-breastfed children were less often overweight [OR: ~0.1 (95% upper limit ≤1.0)]. Neither breastfeeding nor most complementary feeding practices differed by socio-economic status, but children in the highest two fifth of a wealth index had 7.8 (1.3-46.9) and 5.3 (1.1-25.2) times greater odds than children in the lowest fifth of meeting minimum dietary diversity criteria. Low rates of EBF, given possible protection of breastfeeding against overweight, and inadequate dietary diversity offer evidence to guide future program interventions to improve nutritional status of young children.
在南亚,儿童营养不足问题仍然存在,而超重问题却在不断增加。国际推荐的婴幼儿喂养实践(IYCF)可促进健康的营养状况;然而,关于不丹的 IYCF 情况知之甚少,本研究使用了 2015 年国家营养调查数据对此进行了调查。本研究共有 441 名 <24 个月的儿童可获取世卫组织/儿基会 IYCF 指标、人体测量学和家庭社会经济地位数据。生长迟缓、消瘦和体重不足(<-2Z 年龄别身长 [LAZ]、年龄别体重 [WAZ] 和身长别体重 [WLZ])的发生率分别为 15%、9%和 5%,而超重(WLZ >2)的发生率为 6%。在经过调查设计调整的分析中,52%的 0-5 月龄婴儿母亲报告称其婴儿进行了纯母乳喂养(EBF),女孩的 EBF 比例低于男孩(OR:0.2 [95% CI:0.1-0.9])。尽管 61%的儿童在 2 岁时进行母乳喂养,75%的 >6 月龄儿童满足每日最低进餐次数,但仅有 18%的 6-23 月龄儿童满足最低饮食多样性标准。IYCF 与生长迟缓、消瘦或体重不足的风险无关,这可能是由于身体测量失败的相对低发生率和小样本量。然而,目前正在母乳喂养的儿童超重的情况较少[OR:~0.1(95%上限≤1.0)]。母乳喂养或大多数补充喂养实践均与社会经济地位无关,但在财富指数最高的两个五分位数中,儿童满足最低饮食多样性标准的几率分别是财富指数最低的五分位数儿童的 7.8(1.3-46.9)和 5.3(1.1-25.2)倍。鉴于母乳喂养可能有助于预防超重,而目前母乳喂养率较低,饮食多样性不足,这为指导未来的项目干预措施提供了证据,以改善幼儿的营养状况。
