Obesity As a Moderator of the Relationship Between Neighborhood Environment and Objective Measures of Physical Activity in Chilean Adults

The aim of this study was to analyze the association between neighborhood environment and the objective measures of physical activity (PA) according to nutritional status in the adult population. A cross-sectional study design was employed. The information was collected from 161 representative subjects of the CESCAS study population from Temuco- Chile. The perception of the neighborhood environment was determined using the IPAQ Environmental- Module. PA was measured objectively by a triaxial accelerometer for 7 consecutive days. Weight and height were measured. The relationship between the residential environment and the PA levels was summarized through linear regression models stratified by nutritional status. The perceived residential environmental attributes that support active transport were positively associated with total moderate-vigorous PA (MVPA) (β 397 min/week, CI 80–714, p = 0.019) in people with normal nutritional status, but not in overweight and obese individuals. In addition, living near to a public transport stop was associated with higher levels of moderate PA only in normal-weight subjects (β 383 min/week, CI 72–694, p = 0.021). Also living in a neighborhood with traffic safety was associated with higher levels of light PA in normal-weight subjects (β 518 min/week, CI 208–829, p = 0.004). There was no significant association between perceived neighborhood environment and PA in people with obesity.
