我们描述了婴儿期后儿童的生长模式，并确定了发育迟缓和从发育迟缓中恢复的发生率。数据来自Young Lives，这是一项针对四个中低收入国家儿童贫困的纵向研究。我们分析了1岁，5岁和8岁儿童的长度/身高测量。埃塞俄比亚、印度、秘鲁和越南的儿童（n 7171）。1岁时的平均年龄别身高Z评分（HAZ）范围为-1.51（埃塞俄比亚）至-1.08（越南）。从1岁到5岁，埃塞俄比亚的平均HAZ增加了0.27（P<0.001），而其他队列的平均HAZ减少了（范围：-0.19（秘鲁）到-0.32（印度）;所有P<0.001）。从5岁到8岁，所有队列的平均HAZ增加（范围：0.19（印度）到0.38（秘鲁）;所有P<0.001）。1岁时发育迟缓（HAZ<-2·0）的患病率从21%（越南）到46%（埃塞俄比亚）不等。从1岁到5岁，发育迟缓患病率在埃塞俄比亚下降了15.1个百分点（P<0.001），在其他队列中增加（范围：3.0个百分点（越南）到5.3个百分点（印度）;所有P≤ 0.001）。从5岁到8岁，所有队列的发育迟缓患病率均下降（范围：5.0个百分点（越南）至12.7个百分点（秘鲁）;所有P<0.001）。1 - 5岁儿童发育迟缓的发生率范围为11%（越南）至22%（印度）; 5 - 8岁儿童发育迟缓的发生率范围为3%（秘鲁）至6%（印度和埃塞俄比亚）。1 - 5岁儿童发育迟缓的恢复率范围为27%（越南）至53%（埃塞俄比亚）; 5 - 8岁儿童发育迟缓的恢复率范围为30%（印度）至47%（埃塞俄比亚）。我们发现，在四个低收入和中等收入国家，儿童早期发育迟缓得到了实质性恢复。
We characterized post-infancy child growth patterns and determined the incidence of becoming stunted and of recovery from stunting. Data came from Young Lives, a longitudinal study of childhood poverty in four low- and middle-income countries. We analysed length/height measurements for children at ages 1, 5 and 8 years. Children (n 7171) in Ethiopia, India, Peru and Vietnam. Mean height-for-age Z-score (HAZ) at age 1 year ranged from −1·51 (Ethiopia) to −1·08 (Vietnam). From age 1 to 5 years, mean HAZ increased by 0·27 in Ethiopia (P<0·001) and decreased among the other cohorts (range: −0·19 (Peru) to −0·32 (India); all P<0·001). From 5 to 8 years, mean HAZ increased in all cohorts (range: 0·19 (India) to 0·38 (Peru); all P<0·001). Prevalence of stunting (HAZ<−2·0) at 1 year ranged from 21% (Vietnam) to 46% (Ethiopia). From age 1 to 5 years, stunting prevalence decreased by 15·1 percentage points in Ethiopia (P<0·001) and increased in the other cohorts (range: 3·0 percentage points (Vietnam) to 5·3 percentage points (India); all P≤0·001). From 5 to 8 years, stunting prevalence decreased in all cohorts (range: 5·0 percentage points (Vietnam) to 12·7 percentage points (Peru); all P<0·001). The incidence of becoming stunted between ages 1 to 5 years ranged from 11% (Vietnam) to 22% (India); between ages 5 to 8 years, it ranged from 3% (Peru) to 6% (India and Ethiopia). The incidence of recovery from stunting between ages 1 and 5 years ranged from 27% (Vietnam) to 53% (Ethiopia); between ages 5 and 8 years, it ranged from 30% (India) to 47% (Ethiopia). We found substantial recovery from early stunting among children in four low- and middle-income countries.
