Abstract P147: Associations Between Neighborhood Quality and Physical Activity in New Cuban Immigrants
Introduction: Physical inactivity is widespread in the US population. Few longitudinal studies have examined the association between neighborhood environment and change in physical activity behaviors. Recent evidence has shown that “moving to opportunity” may have a positive effect on health and behavior. Our study aimed to determine if moving to a neighborhood with a particular quality level is associated with individual physical activity behaviors among new Cuban immigrants relocating to the US.
Hypothesis: Participants that move into high quality neighborhoods will have smaller declines in physical activity compared to those who move into low quality neighborhoods.
Methods: There were 280 participants included in this analysis [Mean Age: 37.4 (±4.6), 49. 3% (137 of 280) women, Mean baseline BMI: 25.0 (±2.5)]. Information on demographics, physical activity and neighborhood quality was collected from participants at baseline, 12 months and 24 months. The primary outcome measure was time (minutes) spent in MVPA. Minutes of MVPA was measured over 3 days at each follow up period using accelerometers. A neighborhood quality score was calculated for each participant’s baseline census tract by summing the individual z-scores calculated from the following neighborhood variables: median household income, median housing value, % residents that graduated high school, % residents that graduated college, % residents in managerial occupations and % of households receiving interest, dividend or net rental income. The neighborhood quality score was grouped into tertiles that reflected low quality, moderate quality & high quality. Mixed models were used to examine the relationship between change in the amount physical activity over 24 months and neighborhood quality.
Results: Mean time spent in MVPA was 86.7(±55.2), 120(±84.4) and 115.0(±72.2) at baseline, 12 months and 24 months respectively. 94(33.6%) of participants moved to neighborhoods that were considered low quality and 78(27.9%) moved to neighborhoods that were high quality. The crude model showed that change in MVPA over time did not vary by baseline neighborhood quality level (p-value for interaction = 0.72). After adjusting for age, gender and body mass index, there was no difference seen among the neighborhood quality levels (p-value for interaction = 0.71)
Conclusion: The results of this analysis suggest that in new Cuban immigrants, longitudinal changes in MVPA after relocating to the US may not vary by the quality of neighborhood.
