There is growing concern over the double burden of over- and under-nutrition in individuals, especially in children and adolescents, which could dwarf their growth and development. This study aims to explore the rural-urban difference in BMI and anemia among children and adolescents. A stratified cluster sampling technique was employed. Dietary data were collected through interviews, and anthropometric values were measured. There were 1534 children and adolescents who participated in this study, including 775 male and 759 female participants. The prevalence of obesity among children living in a city, township and rural area was 10.3%, 8.5% and 5.5%, and that among adolescents was 1.4%, 2.9% and 2.8%. The prevalence of anemia among children and living in a city, township and rural area was 4.3%, 2.5% and 4.5%, while that among adolescents was 6.1%, 3.7% and 11.3%, respectively, with significant difference (χ² = 10.824, = 0.004). The prevalence of being overweight, obesity and anemia was significant when comparing children with adolescents (χ² = 37.861, = 0.000; χ² = 19.832, = 0.000; χ² = 8.611, = 0.003). Findings of this study indicate the double burden of malnutrition in Zhejiang province, characterized by a high prevalence of being overweight, obesity and anemia among children and a high prevalence of anemia among adolescents living in townships.
个人营养过剩和营养不良的双重负担日益受到关注，尤其是在儿童和青少年中，这可能会阻碍他们的生长发育。本研究旨在探讨儿童和青少年城乡之间的体重指数（BMI）和贫血差异。采用分层整群抽样技术。通过访谈收集饮食数据，并测量人体测量值。共有1534名儿童和青少年参与了本研究，其中男性775名，女性759名。城市、乡镇和农村儿童的肥胖患病率分别为10.3%、8.5%和5.5%，青少年的肥胖患病率分别为1.4%、2.9%和2.8%。城市、乡镇和农村儿童的贫血患病率分别为4.3%、2.5%和4.5%，青少年的贫血患病率分别为6.1%、3.7%和11.3%，差异有统计学意义（χ² = 10.824，P = 0.004）。儿童与青少年相比，超重、肥胖和贫血的患病率差异有统计学意义（χ² = 37.861，P = 0.000；χ² = 19.832，P = 0.000；χ² = 8.611，P = 0.003）。本研究结果表明浙江省存在营养不良的双重负担，其特点是儿童中超重、肥胖和贫血的患病率较高，乡镇青少年中贫血的患病率较高。
