Comparison of Nutritional Status Between Migrant and Nonmigrant School-Age Children in Kunming, Yunnan Province, China

This study explores the nutritional status of migrant and nonmigrant school-age children in Kunming, Yunnan Province, China, along with the contributing factors. A cross-sectional survey (n = 1655) was conducted among students aged 9–11 years across four schools. The findings reveal that 73% of the students’ parents are migrants. Compared with nonmigrants, migrant students exhibited a significantly lower obesity rate (5.2% vs. 8.8%). The migrant parents demonstrated lower levels of nutritional knowledge and education compared to nonmigrants, albeit local parents invested more time in work. Risk factors affecting the nutritional status of migrant children included age, sex, and cooking time, while for local children, gender, family size, sweet food consumption, and nutritional knowledge were identified as risk factors.
