Thinness in children and adolescents poses a considerable public health problem globally, especially in developing countries. The present study examined the prevalence of thinness among children and adolescents in Shandong, China.
Data for this study were obtained from a large cross-sectional survey of schoolchildren. A total of 42,348 students (21,248 boys and 21,100 girls) aged 7-18 years participated in this study. Stature and weight of all subjects were measured; body mass index (BMI) was calculated from their stature and weight. International BMI cutoffs were used to define thinness.
The overall prevalences of thinness grade 1, grade 2 and grade 3 among children and adolescents aged 7-18 years were 7.74, 1.43 and 0.61 % for boys and 11.51, 2.54 and 1.03 % for girls, respectively; these figures were all significantly higher in girls than in boys (P < 0.01). Thin children and adolescents had lower stature levels than their counterparts in not thin group in all age groups (7-18 years).
The prevalence of childhood thinness is still wide in Shandong Province, and public health and nutritional strategies must give attention to the intervention for thinness, including periodic monitoring, education on pattern of nutrition and healthy dietary behavior.
儿童和青少年消瘦是一个全球性的重大公共卫生问题，尤其是在发展中国家。本研究旨在调查中国山东省儿童和青少年消瘦的流行情况。
本研究的数据来自一项对学龄儿童的大型横断面调查。共有 42348 名 7-18 岁的学生（男生 21248 人，女生 21100 人）参与了这项研究。所有受试者的身高和体重均进行了测量，并根据其身高和体重计算了体重指数（BMI）。采用国际 BMI 切点来定义消瘦。
7-18 岁儿童和青少年消瘦 1 级、2 级和 3 级的总体患病率分别为男生 7.74%、1.43%和 0.61%，女生 11.51%、2.54%和 1.03%；女生的患病率均显著高于男生（P < 0.01）。消瘦儿童和青少年在所有年龄组中的身高水平均低于非消瘦组（7-18 岁）。
山东省儿童消瘦的患病率仍然较高，公共卫生和营养策略必须重视消瘦的干预，包括定期监测、营养模式教育和健康饮食行为。
