Abstract

We investigate the effects of diet diversity on health outcomes indicated by the body-mass index (BMI) of Kenyan women in their reproductive age (15–49 years). We estimate the demand for diet diversity (which is a proxy for diet quality) and analyse its relationship with BMI by allowing the effect of diet diversity to vary along the conditional BMI distribution. Results show that diet diversity is associated with a beneficial effect on the lower and upper tails of the BMI distribution, that is, dietary diversity improves BMI for underweight individuals while, at the same time, it reduces BMI for overweight/obese individuals. Specifically, doubling the diet diversity is associated with a 14.7% increase in BMI for underweight women and a 7.0% reduction in BMI of obese women. These results support the hypothesis that diet diversity is associated with optimal BMI and, thus, better health, contributing to the policy discourse concerning the double burden of malnutrition in developing countries.

饮食多样性、营养不良和健康:来自肯尼亚的证据
我们研究了饮食多样性对肯尼亚育龄妇女(15-49岁)身体质量指数(BMI)所显示的健康结果的影响。我们估计了对饮食多样性的需求(这是饮食质量的代表),并通过允许饮食多样性的影响沿着条件BMI分布变化来分析其与BMI的关系。结果表明,饮食多样性对BMI分布的上下尾均有有益影响,即饮食多样性提高了体重过轻个体的BMI,同时降低了超重/肥胖个体的BMI。具体来说,饮食多样性增加一倍,体重过轻女性的身体质量指数增加14.7%,肥胖女性的身体质量指数下降7.0%。这些结果支持了饮食多样性与最佳BMI相关的假设,从而改善了健康状况,有助于有关发展中国家营养不良双重负担的政策论述。
