The Association of Residential Mobility With Weight-Related Health Behaviors
Journal of Nutrition Education and Behavior(2022)
摘要
Objective
To estimate associations of residential mobility with body mass index (BMI), physical activity, and diet and whether associations differ across demographics.
Design
Longitudinal cohort with 4 waves of survey follow-up over 15 years.
Participants and Setting
A total of 2,110 adolescents and young adults originally from the Twin Cities of Minnesota responded to at least 2 waves of follow-up, beginning at ages 15 to 23 years.
Main Outcome Measure(s)
Self-reported BMI, physical activity, fast food consumption, breakfast frequency, sugary drink consumption, fruit and vegetable consumption, and screen time.
Analysis
Each outcome was modeled as a continuous variable using hierarchical linear regression. Residential mobility—change in residential address—was the main effect of interest. Models adjusted for demographics, marriage during follow-up, and previous level of the outcome. Inverse propensity weights accounted for loss to follow up.
Results
No weight-related outcomes differed between movers and nonmovers in the whole sample. When examining effect modification by age, as participants aged, moving was increasingly associated with improvements in weight-related outcomes, particularly BMI.
Conclusions and Implications
Results suggest that moving may be associated with poorer weight-related outcomes during a brief window from late teens and early-20s and less associated with weight-related outcomes in the mid-20s and 30s.
