Determinants of Weight Disorders in Two- Year- Old Children in Isfahan, Iran

BACKGROUND: Considering the importance of weight disorders in childhood and its impact until adulthood, this study was conducted to assess the determinants of weight disorders in 2-year-old Iranian children. MATERIALS AND METHODS: This cross-sectional study was conducted in 2020 among on 2300 children registered in Comprehensive Health Centers of Isfahan, Iran. Weight disorders, including underweight and overweight were defined according to the standardized National Center for Health Statistics (NCHS)/Centers for Disease Control (CDC) growth charts. Demographic data including gender, birth weight, maternal educational levels and occupation, duration of breastfeeding and the age of beginning complementary food were gathered. RESULTS: In the present study, 750 children (i.e., 32.6%) had weight disorders. Among them, 53.6% were underweight, 26.3% were overweight, and 12.9% were obese, 7.2%had severe underweight. Female gender, university education of mothers and higher levels of socio-economic status significantly increased the chance of overweight by 14.79%, 22.28%, 27.33% and 24.48%, respectively. Although with the increase in the duration of breastfeeding and the increase of family members, overweight, respectively, decreased by 0.86 and 0.93 fold, but it was not statistically significant. There was an inverse, significant relationship between the duration of breastfeeding with overweight versus underweight. CONCLUSION: Underweight and overweight were the two most common weight disorders among 2-year- children, respectively. Control of modifiable risk factors for weight disorders in early life should be underscored in the primary health care system.
