Abstract
Background/objectives
Vietnam is undergoing a nutrition transition, which is leading to marked shifts in body size at the population level, but up-to-date data are lacking. We therefore quantified the prevalence of undernutrition (stunting and thinness) and overnutrition (overweight, obesity, and abdominal obesity) in school-aged children in Ho Chi Minh City (HCMc), Vietnam, and compared this with previous estimates.
Subjects/methods
A cross-sectional survey of 10,949 children (6–18 years old) from 30 schools in HCMc, Vietnam in 2014–2015 was used to ascertain the nutritional status of children and adolescents. Different international classification systems (WHO, IOTF, IOTF for Asian children) were used to assess the prevalence of under and overnutrition. Comparisons were made with previous surveys in HCMc.
Results
Regardless of definitions used, the prevalence of overnutrition was high, particularly in primary school children (20–30% were overweight, 20–30% were obese, and 50% had abdominal obesity), in boys, and urban children. Undernutrition was more prevalent in high-school children (8% were stunted, and 6–18% were thin, versus 2 and 2–9% in primary children, respectively), and in rural areas. Comparisons with previous surveys indicated substantial increases in overnutrition and decreased in undernutrition since 2009 in all age groups.
Conclusions
Overnutrition is increasingly common in school-aged children and adolescents in HCMc, while over and undernutrition continue to coexist. These findings highlight an urgent need for greater efforts to control malnutrition in children in HCMc.
