Social and economic changes associated with new roads can bring about rapid nutritional transitions. To study this process, we: (1) describe trends in adult overweight and obesity (OW/OB) among rural Afro-Ecuadorians over time and across a gradient of community remoteness from the nearest commercial centre; (2) examine the relationship between male and female adult OW/OB and factors associated with market integration such as changing livelihoods and (3) examine the co-occurrence of adult OW/OB and under-five stunting and anaemia.
Adult anthropometry was collected through serial case-control studies repeated over a decade across twenty-eight communities. At the same time, anthropometry and Hb were measured for all children under 5 years of age in every community.
Northern coastal Ecuador.
Adults (n 1665) and children under 5 years of age (n 2618).
From 2003 and 2013, OW/OB increased from 25·1 % to 44·8 % among men and 59·9 % to 70·2 % among women. The inverse relationship between remoteness and OW/OB in men was attenuated when adjusting for urban employment, suggesting that livelihoods mediated the remoteness-OW/OB relationship. No such relationship was observed among women. Communities with a higher prevalence of male OW/OB also had a greater prevalence of stunting, but not anaemia, in children under 5 years of age.
The association between male OW/OB and child stunting at the community level, but not the household level, suggests that changing food environments, rather than household- or individual-level factors, drove these trends. A closer examination of changing socio-economic structures and food environments in communities undergoing rapid development could help mitigate future public health burdens.
与新道路相关的社会和经济变化可能带来快速的营养转型。为了研究这一过程,我们:(1)描述随着时间的推移和距离最近商业中心的社区偏远程度的梯度,农村非洲裔厄瓜多尔成年人超重和肥胖(OW/OB)的趋势;(2)研究男性和女性成年 OW/OB 与市场融合相关因素(如生计变化)之间的关系;(3)研究成年 OW/OB 与五岁以下儿童发育迟缓与贫血的共现。
通过十年来在 28 个社区反复进行的系列病例对照研究收集成年人的人体测量数据。与此同时,在每个社区中,还对所有五岁以下儿童进行了人体测量和 Hb 测量。
厄瓜多尔北部沿海地区。
成年人(n=1665)和五岁以下儿童(n=2618)。
从 2003 年到 2013 年,男性 OW/OB 从 25.1%增加到 44.8%,女性 OW/OB 从 59.9%增加到 70.2%。在调整城市就业情况后,男性的偏远程度与 OW/OB 之间的负相关关系减弱,这表明生计中介了偏远程度与 OW/OB 之间的关系。女性中则未观察到这种关系。男性 OW/OB 患病率较高的社区,五岁以下儿童的发育迟缓率也较高,但贫血率则不然。
社区层面男性 OW/OB 与儿童发育迟缓之间的关联,而不是家庭层面,表明变化的食物环境,而不是家庭或个人层面的因素,推动了这些趋势。对正在经历快速发展的社区中不断变化的社会经济结构和食物环境进行更仔细的研究,可以帮助减轻未来的公共卫生负担。
