Household Income Moderates Longitudinal Relations Between Neighborhood Child Opportunity Index and BMI Growth

Area of Science:

• Environmental Health
• Pediatric Health
• Sociology

Background:

• Childhood obesity is a growing public health concern.
• Neighborhood characteristics, such as child opportunity, may influence health trajectories.
• Socioeconomic factors can mediate the relationship between environment and health outcomes.

Purpose of the Study:

• To investigate the longitudinal relationship between early neighborhood Child Opportunity Index 2.0 (COI) and children's BMI trajectories.
• To determine if household economic resources moderate the impact of neighborhood COI on BMI growth from ages 2 to 12 years.

Main Methods:

• Longitudinal study of 1091 families from rural, high-poverty areas.
• Neighborhood COI assessed during infancy/toddlerhood and preschool years.
• BMI calculated from anthropometrics collected at six time points between ages 2 and 12 years.

Main Results:

• Higher neighborhood COI in infancy/toddlerhood and preschool years correlated with lower BMI at age 5.
• Household income and poverty duration moderated the association between early neighborhood COI and BMI change.
• In non-poor households, higher neighborhood COI predicted slower BMI increase and lower BMI at age 12.

Conclusions:

• Early neighborhood opportunity is longitudinally associated with child growth patterns.
• The impact of neighborhood opportunity on BMI trajectories is more pronounced in children from non-poor households.
• Further research is needed to understand the interplay of family and neighborhood resources in obesity risk.
