Early Life Factors for Overweight Risk Among Infants of Hispanic Immigrant Mothers

Area of Science:

• Pediatrics
• Public Health
• Maternal-Child Health

Background:

• Infant overweight and obesity are significant public health concerns, particularly among vulnerable populations.
• Early life factors can influence long-term weight status.
• Hispanic immigrant mothers represent a population at risk for adverse infant health outcomes.

Purpose of the Study:

• To investigate the association between early life factors (postpartum depression, food insecurity, underestimation of infant size) and overweight risk at 12 months in infants of Hispanic immigrant mothers.

Main Methods:

• Weight-for-length (WFL) measurements and interviews were conducted during well-child visits.
• Regression models were used to analyze the impact of early life factors (0-6 months) on overweight risk at 1 year.

Main Results:

• Infant overweight risk increased from 2.4% at birth to 42.7% at 1 year.
• Maternal food insecurity (78.6%) increased overweight risk by 2.29 times.
• Maternal underestimation of infant size increased overweight risk by 5.07 times.
• Postpartum depression was not found to be a significant factor in infant weight status.

Conclusions:

• Assessing maternal food insecurity and underestimation of infant weight status in early infancy is crucial for intervention.
• Targeted interventions can help reduce overweight risk and prevent subsequent obesity in this high-risk population.
