Abstract

Background: To understand the multifaceted causes of obesity, numerous studies have investigated how the neighborhood food environment is associated with diet. This literature has focused almost exclusively on home neighborhood environments in urban settings while the neighborhood food environment around an individual’s workplace has received little attention. We tested the hypothesis that fast food restaurant (FFR) availability around the workplace is more strongly related to dietary behaviors than FFR availability around the home for rural women.

Methods: In 2013 we conducted a cross-sectional analysis of Astoria Warrenton Heart Health Initiative (AWWHHI) participants (20-69 years of age, coastal towns in Oregon) who worked outside the home (n=142). Using a Geographic Information System (GIS) we calculated the availability of FFRs by closest distance to a FFR and number of FFRs within 400 and 800 meters of the women’s home and workplace. Descriptive analysis and multivariate regression models were used to determine the association between availability of FFRs in home and workplace neighborhoods and women’s diet (Fast Food, Fruit & Vegetable, and Sugar Sweetened Beverage (SSB) intake), controlling for household income, age, marital status, and child living at home.

Results: Greater Fast Food consumption was associated with greater FFR availability within 800 of homes [OR (95%CI): 2.35 (1.06, 5.22)] and shorter distance from home to nearest FFR [OR (95%CI): 0.73 (0.55, 0.97)]. SSB intake was positively associated with FFR availability around home but these associations were not statistically significant. Greater FFR availability around work had non-significant negative associations with Fast Food consumption and SSB intake (p>0.1). Fruit & Vegetable intake was not associated with FFR availability around home or work. Associations between FFR availability and dietary outcomes were similar when FFR availability around home and work were combined.

Conclusion: FFR availability around the home, but not the workplace, was associated with greater Fast Food consumption. These associations were not observed for Fruit & Vegetable or SSB intake. Investigation of other environmental or social determinants of dietary behaviors in rural women is needed.
