A propitiously timed household survey carried out in Mozambique over the period 2008/2009 permits us to study the relationship between shifts in food prices and child nutrition status in a low income setting. We focus on weight-for-height and weight-for-age in different survey quarters characterized by very different food price inflation rates. Using propensity score matching techniques, we find that these nutrition measures, which are sensitive in the short run, improve significantly in the fourth quarter of the survey, when the inflation rate for basic food products is low, compared to the first semester or three quarters, when food price inflation was generally high. The prevalence of underweight, in particular, falls by about 40 percent. We conclude that the best available evidence points to food penury, driven by the food and fuel price crisis combined with a short agricultural production year, as substantially increasing malnutrition amongst under-five children in Mozambique.
2008年至2009年期间在莫桑比克进行的一次时机恰到好处的家庭调查,使我们能够在低收入环境中研究食品价格变化与儿童营养状况之间的关系。我们关注不同调查季度的身高别体重和年龄别体重,这些季度的食品价格通胀率差异很大。使用倾向得分匹配技术,我们发现,这些在短期内较为敏感的营养指标,在调查的第四季度有显著改善,此时基本食品的通胀率较低;而在第一学期或前三季度,食品价格通胀普遍较高。特别是,体重不足的发生率下降了约40%。我们的结论是,现有最佳证据表明,由食品和燃料价格危机以及农业生产年较短导致的食品匮乏,极大地加剧了莫桑比克五岁以下儿童的营养不良状况。
