Neighborhood walkability linked to lower type 2 diabetes risk in women with prior gestational diabetes
More walkable neighborhoods in New York City were associated with a lower risk of developing postpartum type 2 diabetes among women who had gestational diabetes mellitus (GDM), according to a new study from Columbia University Mailman School of Public Health. However, the association varied depending on individual and neighborhood socioeconomic circumstances, including Medicaid coverage and…
A recent study published in Diabetes Care reveals a potential link between neighborhood walkability and reduced risk of type 2 diabetes in women who previously experienced gestational diabetes mellitus (GDM). The research, conducted by Columbia University Mailman School of Public Health, found that women residing in neighborhoods with medium levels of walkability had a 15% lower likelihood of developing postpartum type 2 diabetes compared to those in less-walkable areas, over a 12-year follow-up period.
Bohao Wu, Ph.D., the study's lead author, highlighted that while GDM typically resolves post-delivery, it remains a significant risk factor for future type 2 diabetes. The study aimed to uncover whether neighborhood environments could influence the development of type 2 diabetes in women with GDM, an area previously lacking substantial evidence.
The researchers analyzed data from the APPLE study, a population-based cohort of women who delivered in New York City between 2009 and 2011. They identified 12,403 women with GDM and followed them through 2021, recording 21% developing type 2 diabetes within the 12-year period.
The study's statistical modeling revealed that the association between high neighborhood walkability and lower diabetes risk was only observed among women living in affluent neighborhoods. This finding underscores the complexity of neighborhood context, suggesting that while increasing walkability is a desirable planning goal, policies must also address economic disadvantage to maximize health benefits.
Teresa Janevic, Ph.D., senior author and associate professor of epidemiology, emphasized that neighborhood walkability should be considered alongside broader socioeconomic factors, including economic deprivation, social cohesion, and access to health-promoting resources. The study concludes that efforts to create walkable communities could be more effective when paired with strategies that tackle the broader social and economic conditions affecting residents' ability to benefit from the built environment.
