Sub-Saharan Africa is the last region to undergo a nutrition transition and can still avoid its adverse health outcomes.
The article explores emerging responses to "bend the curve" in sub-Saharan Africa's nutrition transition to steer public health outcomes onto a healthier trajectory.
Early responses in 3 countries at different stages of food system transformation are examined: South Africa-advanced, Ghana-intermediate, and Uganda-early. By comparing these with international experience, actions are proposed to influence nutrition and public health trajectories as Africa's food systems undergo rapid structural change.
Arising from rapid urbanization and diet change, major public health problems associated with overweight are taking place, particularly in South Africa and among adult women. However, public health responses are generally tepid in sub-Saharan Africa. Only in South Africa have policy makers instituted extensive actions to combat overweight and associated noncommunicable diseases through regulation, education, and public health programs. Elsewhere, in countries in the early and middle stages of transition, public health systems continue to focus their limited resources primarily on undernutrition. Related pressures on the supply side of Africa's food systems are emerging that also need to be addressed.
Three types of intervention appear most feasible: maternal and child health programs to simultaneously address short-term undernutrition problems while at the same time helping to reduce future tendencies toward overweigh; regulatory and fiscal actions to limit access to unhealthy foods; and modernization of Africa's agrifood food system through job skills training, marketing reforms, and food industry entrepreneurship.
撒哈拉以南非洲是最后一个经历营养转型的地区,仍可避免其不良健康后果。
本文探讨了撒哈拉以南非洲营养转型中对“扭转趋势”的新应对措施,以引导公共卫生结果走上更健康的轨道。
研究了处于粮食系统转型不同阶段的3个国家的早期应对措施:南非——先进阶段、加纳——中间阶段、乌干达——早期阶段。通过将这些与国际经验进行比较,提出了在非洲粮食系统经历快速结构变化时影响营养和公共卫生轨迹的行动建议。
由于快速城市化和饮食变化,与超重相关的主要公共卫生问题正在出现,特别是在南非以及成年女性中。然而,撒哈拉以南非洲的公共卫生应对措施总体上较为迟缓。只有南非的政策制定者通过监管、教育和公共卫生项目采取了广泛行动来对抗超重及相关的非传染性疾病。在其他地方,处于转型早期和中期的国家,公共卫生系统继续将其有限资源主要集中在营养不良问题上。非洲粮食系统供应方面的相关压力也正在出现,也需要加以解决。
三种干预措施似乎最可行:母婴健康项目,以同时解决短期营养不良问题,同时帮助减少未来超重的趋势;监管和财政行动,以限制获取不健康食品;通过职业技能培训、市场改革和食品行业创业实现非洲农业食品系统现代化。
