Abstract

Background

Early childhood obesity is an increasing public health problem with long-term consequences. Identifying risk factors is essential for effective prevention strategies.

Aim

To evaluate prenatal, perinatal, and postnatal influences; breastfeeding and nutritional practices, lifestyle and daily habits; household, sociocultural, and economic conditions; and parental anthropometric characteristics to better elucidate the determinants of obesity in early childhood                                                                                                                      

Methods

This cross-sectional study included 210 children aged 12–60 months, comprising 104 children with obesity and 106 non-obese controls. Standardized anthropometric assessments were performed in all participants. Parents completed a structured questionnaire capturing perinatal characteristics, infant feeding practices, dietary intake, medical history, lifestyle behaviors, and household-level factors.

Results

A total of 210 children (113 females) were included (106 obese and 104 non-obese), with comparable age between groups (3.4 ± 1.3 vs. 3.3 ± 1.3 years). Both maternal and paternal BMI values were significantly higher in the obese group, and maternal employment (27.4% vs. 5.8%) and maternal obesity (42.5% vs. 21.2%) were more prevalent. Maternal smoking during pregnancy (23.6% vs. 7.7%) and gestational diabetes (22.6% vs. 9.6%) were also more frequent. Feeding practices and current dietary patterns did not differ significantly between groups. In multivariable analysis, maternal employment (aOR 3.74), sibling obesity (aOR 2.21), and extended family obesity burden (aOR 1.19) independently predicted childhood obesity.

Conclusion

Familial obesity burden showed the strongest associations with obesity, highlighting the need for early identification of high-risk children and family-centered preventive strategies focusing on physical activity, diet, and daily routines.
