Sub-Saharan Africa is experiencing the double burden of malnutrition (DBM) with high levels of undernutrition and a growing burden of overweight/obesity and diet-related noncommunicable diseases (NCDs). Undernourishment in sub-Saharan Africa increased between 2010 and 2016. Although the prevalence of chronic undernutrition is decreasing, the number of stunted children under 5 years of age is increasing due to population growth. Meanwhile, overweight/obesity is increasing in all age groups, with girls and women being more affected than boys and men. It is increasingly recognized that the drivers of the DBM originate outside the health sector and operate across national and regional boundaries. Largely unregulated marketing of cheap processed foods and nonalcoholic beverages as well as lifestyle changes are driving consumption of unhealthy diets in the African region. Progress toward the goal of ending hunger and malnutrition by 2030 requires intensified efforts to reduce undernutrition and focused action on the reduction of obesity and diet-related NCDs. The World Health Organization is developing a strategic plan to guide governments and development partners in tackling all forms of malnutrition through strengthened policies, improved service delivery, and better use of data. It is only through coordinated and complementary efforts that strides can be made to reduce the DBM.
撒哈拉以南非洲正面临营养不良的双重负担(DBM),存在严重的营养不足问题,同时超重/肥胖和与饮食相关的非传染性疾病(NCD)的负担也在不断增加。撒哈拉以南非洲的营养不足现象在 2010 年至 2016 年间有所增加。尽管慢性营养不良的患病率在下降,但由于人口增长,5 岁以下发育迟缓儿童的数量仍在增加。与此同时,超重/肥胖现象在所有年龄段都在增加,女孩和妇女比男孩和男人受影响更大。人们越来越认识到,DBM 的驱动因素源于卫生部门之外,并在国家和地区边界内运作。廉价加工食品和非酒精饮料的营销基本上不受监管,以及生活方式的改变,正在推动非洲地区不健康饮食的消费。要实现到 2030 年消除饥饿和营养不良的目标,就需要加强努力减少营养不足,并集中力量减少肥胖和与饮食相关的 NCD。世界卫生组织正在制定一项战略计划,通过加强政策、改善服务提供和更好地利用数据,指导各国政府和发展伙伴应对所有形式的营养不良。只有通过协调和互补的努力,才能在减少 DBM 方面取得进展。
