This article examines trends in the nutritional status of children in EI Salvador between 1988 and 1993 (before and after the signing of a peace accord that ended the civil war.) The data derive from two national surveys, each of which included measurements of the height and weight of children aged 3-59 months. The prevalence of low weight-for-age (< -2 SD) dropped from 15% in 1988 to 10.5% in 1993. The prevalence of low weight-for-height (< -2 SD) was minimal in both surveys: falling from 3.9% to 2.9%. The prevalence of low height-for-age (< -2 SD) fell from 28.1% to 22%. These declines in malnutrition indicators resulted from an upward shift in the distributions of weight and height of children, not from thinner lower tails of the distributions. The quality of anthropometric data appears to be high for both surveys: < 1% of surveyed children had heights or weights outside the expected range. This analysis demonstrates the value of repeated surveys of nutritional status.
本文研究了1988年至1993年期间萨尔瓦多儿童的营养状况趋势(在内战结束的和平协议签署前后)。数据来自两项全国性调查,每项调查都包括对3至59个月大儿童的身高和体重测量。年龄别低体重(<-2标准差)的患病率从1988年的15%降至1993年的10.5%。身高别低体重(<-2标准差)的患病率在两项调查中都很低:从3.9%降至2.9%。年龄别低身高(<-2标准差)的患病率从28.1%降至22%。这些营养不良指标的下降是由于儿童体重和身高分布的向上偏移,而非分布的较低尾部变窄。两项调查中人体测量数据的质量似乎都很高:<1%的被调查儿童的身高或体重超出预期范围。该分析证明了重复进行营养状况调查的价值。
