Neighborhood socioeconomic differences in BMI: The role of fast‐food outlets and physical activity facilities
Authors' conclusion
People living in lower NSES areas had a higher BMI, independent of their individual socioeconomic status. The study found no clear moderation of FF outlets and PA facilities. Environmental factors that may mitigate NSES differences in BMI should be the subject of future research.
Study context
- Population
- Adults in Lifelines (baseline data), Netherlands; Fast-food (FF) outlets and pay-for-use physical activity (PA) facilities within 1 km of residence
- Participants
- 146,629 Lifelines adults
- Exposure
- Low vs middle vs high neighbourhood socioeconomic status
- Outcome
- BMI
- Follow-up
- Baseline
Methodological detailsmultilevel linear regression, geocoding-linked register data
- Multilevel linear regression

Main finding
As reported in the abstract
B
0.76
95% CI 0.65–0.87
Low neighborhood socioeconomic status (NSES) vs High NSES
B
0.40
95% CI 0.28–0.51
Low NSES vs Middle NSES
Observational data: associations, not effects.
Further findings
- Two- and three-way interactions between NSES, FF outlets and PA facilities were significant, but stratified analyses showed no consistent moderation patterns
