Food intake inequality at the individual level is rarely analyzed in intrahousehold settings. We examine dietary diversity scores of household members with a focus on their family roles (fathers, mothers, sons, daughters and grandparents) and age groups (children, adults and elderly). Whereas theory suggests that members in a household should have equal dietary diversity by receiving a certain share of available foods, this research hypothesizes that they do not do so by their roles and/or age groups. We conduct questionnaire surveys, collecting sociodemographic information and dietary data by using a 24 h recall method of 3248 subjects in 811 households from 1 urban and 2 rural areas in Bangladesh. The statistical analysis demonstrates three findings. First, poor and rural people have lower dietary diversity than nonpoor and urban people, respectively. Second, grandparents (children) have lower dietary diversity than do fathers (adults), confirming the existence of intrahousehold food intake inequality by the roles and/or age groups, irrespective of poverty level and areas of residence. Third, father and mother educations are crucial determinants that raise the dietary diversity of household members; however, they do not resolve the inequality. Overall, it is suggested that awareness programs of dietary diversity shall be necessary with a target group of fathers and mothers for the betterment of intrahousehold inequality and health at the household level, contributing to sustainable development goals.
个体层面的食物摄入不平等在家庭内部很少被分析。我们关注家庭成员的饮食多样性评分,重点关注他们的家庭角色(父亲、母亲、儿子、女儿和祖父母)和年龄组(儿童、成年人和老年人)。尽管理论表明,家庭成员应该通过获得一定份额的可用食物来享有平等的饮食多样性,但这项研究假设他们并没有通过角色和/或年龄组来实现这一点。我们进行了问卷调查,通过在孟加拉国 1 个城市和 2 个农村地区的 811 户家庭中,对 3248 名受访者采用 24 小时回顾法收集了社会人口学信息和饮食数据。统计分析表明了三个发现。首先,穷人、农村居民的饮食多样性比非贫困人口、城市居民低。其次,与父亲(成年人)相比,祖父母(儿童)的饮食多样性较低,证实了家庭内部食物摄入不平等的存在,这与贫困程度和居住地区无关。第三,父亲和母亲的教育是提高家庭成员饮食多样性的关键决定因素;然而,他们并不能解决不平等问题。总的来说,建议开展饮食多样性的宣传教育活动,目标人群是父亲和母亲,以改善家庭内部的不平等状况和家庭层面的健康水平,为可持续发展目标做出贡献。
