Child undernutrition remains one of the greatest challenges for public health nutrition in rural areas in developing countries. Interventions aiming to increase and conserve agrobiodiversity seem to be promising alternatives to improve child nutrition. However, the existing literature on these interventions is not conclusive about their effectiveness in combating child undernutrition. We tested the hypothesis that 'higher agrobiodiversity is associated with greater dietary diversity and better anthropometric status' in rural Guatemala.Design/Setting/SubjectsIn the summer of 2016, we conducted a cross-sectional study with a sample of 154 children (6-60 months). We conducted dietary recalls and structured interviews, measured children's weight and height, and visited food production systems (Milpas, home gardens, coffee plantations). Crop species richness, nutritional functional diversity, dietary diversity scores and anthropometric status were calculated.
Higher food self-sufficiency, nutritional functional diversity and dietary diversity scores were positively correlated with higher crop and animal species richness. Contrarily, remoteness to the local market was negatively correlated with dietary diversity scores. However, higher dietary diversity scores were not correlated with better child anthropometric status. Better child anthropometric status was positively correlated with improved sanitary conditions and maternal education; and negatively correlated with large household size and frequent child morbidity.
Agricultural diversification could diversify diets, increase nutrient availability and improve child anthropometry. However, these interventions need to be accompanied by sanitation improvements, family planning, nutritional education and women's empowerment to strengthen their positive effect on diet and nutrition.
儿童营养不良仍然是发展中国家农村地区公共卫生营养面临的最大挑战之一。旨在增加和保护农业生物多样性的干预措施似乎是改善儿童营养的有希望的替代方法。然而,关于这些干预措施的现有文献对于它们在对抗儿童营养不良方面的有效性并没有定论。我们检验了这样一个假设,即在危地马拉农村,“更高的农业生物多样性与更大的饮食多样性和更好的人体测量学状况相关”。
设计/环境/研究对象:2016 年夏天,我们进行了一项横断面研究,样本为 154 名儿童(6-60 个月)。我们进行了饮食回忆和结构化访谈,测量了儿童的体重和身高,并访问了粮食生产系统(Milpa、家庭菜园、咖啡种植园)。计算了作物物种丰富度、营养功能多样性、饮食多样性评分和人体测量学状况。
更高的粮食自给自足、营养功能多样性和饮食多样性评分与更高的作物和动物物种丰富度呈正相关。相反,离当地市场的距离与饮食多样性评分呈负相关。然而,更高的饮食多样性评分与儿童更好的人体测量学状况没有相关性。更好的儿童人体测量学状况与改善的卫生条件和母亲教育呈正相关;与大家庭规模和儿童频繁患病呈负相关。
农业多样化可以使饮食多样化,增加营养供应,并改善儿童的人体测量学状况。然而,这些干预措施需要与卫生改善、计划生育、营养教育和妇女赋权相结合,以加强它们对饮食和营养的积极影响。
