背景。最近农产品价格大幅上涨，至少在中期，食品价格很可能会延续上涨趋势。此外，最近的金融危机还降低了收入，提高了食品价格。这不仅会降低饮食质量，而且保健、卫生和教育方面的支出也会下降，所有这些都将对健康和营养结果产生不利影响。就主要社会经济因素在推动健康和营养结果方面的作用提供一些观点。我们使用从家庭调查数据中估计的需求弹性参数来模拟食品价格的上涨，然后将其映射到能量和营养摄入量中。此外，我们还使用家庭层面的数据来分析家庭内部食物分配不平等对成年妇女和女童营养状况的影响。食品价格上涨50%，会导致能量摄入量减少5%至15%，铁摄入量减少10%至30%，这取决于诱发收入效应的强度。在菲律宾这样的国家，这相当于铁摄入量不达标的女性比例增加了25个百分点。食品价格的上涨将使发展中国家对抗微量营养素营养不良变得更加困难。在家庭内部分配副食品时优先考虑男性的社会中，这一目标将更具挑战性。
Background. The recent rise in agricultural commodity prices has been dramatic, and food prices are likely to follow an upward trend, at least in the medium term. Moreover, the recent financial crisis has also lowered incomes and increased food prices. Not only does this reduce dietary quality, but expenditures for health, sanitation, and education will decline, all of which will have a detrimental effect on health and nutrition outcomes.Objective. To provide some perspectives on the role of major socioeconomic factors in driving health and nutrition outcomes.Methods. We use demand elasticity parameters estimated from household-level survey data to simulate an increase in food prices, which is then mapped into energy and nutrient intakes. Furthermore, we also use household-level data to analyze the implications of unequal intrahousehold distribution of food for the nutritional status of adult women and female children.Results. A 50% increase in food prices results in a decrease in energy intake of 5% to 15% and in a decrease in iron intake of 10% to 30%, depending on the strength of the induced income effect. In a country like the Philippines, this would be equivalent to an increase of 25 percentage points in the proportion of women not meeting their requirements for iron intake.Conclusions. Increasing food prices will make fighting micronutrient malnutrition in developing countries more difficult. In societies where preference is given to males in the intrahousehold distribution of nonstaple foods, this objective will be even more challenging.
