The co-existence of underweight and overweight is a great challenge for public health in low-income and middle-income countries (LMICs).
The objective of the study is to report the prevalence of underweight, overweight and obesity among young adolescents in 58 LMICs.
Data were from the Global School-based Student Health Survey (2007-2013) in 57 LMICs and from the Chinese National Surveys on Students' Constitution and Health (2010). A total of 177 325 young adolescents aged 12-15 years from 58 LMICs were included. Weight status was defined based on both the updated International Obesity Task Force (IOTF) and World Health Organization (WHO) criteria.
Based on the IOTF/WHO criteria, the overall prevalence of weight categories among young adolescents in LMICs was 13.4%/4.7% for underweight, 15.4%/17.3% for overweight and 5.6%/8.6% for obesity. However, the prevalence varied largely across countries and regions. Based on the IOTF criteria, the prevalence of underweight ranged from 0.0% in Niue to 48.8% in Sri Lanka and obesity ranged from 0.1% in Vanuatu to 35.0% in Niue; a prevalence exceeding 10.0% for both underweight and excess weight (overweight and obesity combined) was found in 29.3% of these countries. Underweight was more prevalent in Southeast Asia and Africa, while obesity was more frequent in Central and South Americas. There were no age and sex differences in the prevalence of weight categories for most countries.
Our data confirm the continued dual burden of underweight and overweight in young adolescents in many LMICs and the need for policy and programmes to address both conditions.
体重过轻与超重并存对低收入和中等收入国家（LMICs）的公共卫生构成了巨大挑战。
本研究旨在报告58个低收入和中等收入国家青少年中体重过轻、超重和肥胖的患病率。
数据来自57个低收入和中等收入国家的全球学校学生健康调查（2007 - 2013年）以及中国学生体质与健康调研（2010年）。共纳入了来自58个低收入和中等收入国家的177325名12 - 15岁青少年。体重状况根据更新后的国际肥胖特别工作组（IOTF）和世界卫生组织（WHO）标准定义。
根据IOTF/WHO标准，低收入和中等收入国家青少年体重分类的总体患病率为体重过轻13.4%/4.7%，超重15.4%/17.3%，肥胖5.6%/8.6%。然而，患病率在不同国家和地区差异很大。根据IOTF标准，体重过轻的患病率从纽埃的0.0%到斯里兰卡的48.8%不等，肥胖患病率从瓦努阿图的0.1%到纽埃的35.0%不等；在这些国家中，29.3%的国家体重过轻和超重（超重和肥胖合并）患病率均超过10.0%。体重过轻在东南亚和非洲更为普遍，而肥胖在中南美洲更为常见。大多数国家体重分类的患病率不存在年龄和性别差异。
我们的数据证实了许多低收入和中等收入国家青少年中体重过轻和超重这一双重负担依然存在，以及制定政策和计划来解决这两种情况的必要性。
