Description:OBJECTIVE:
To examine whether density of neighborhood restaurants affected frequency of eating restaurant meals and subsequently affected diet quality.
DESIGN:
Cross-sectional and longitudinal designs. Restaurant density within three miles of participant addresses was linked to their Healthy Eating Index (HEI 2010, derived from a food frequency questionnaire) and frequency of eating restaurant meals. Using structural equation models, analyses adjusted for socio-demographics, select health conditions, region, residence duration, and area-level income.
SETTING:
Urbanized areas in multiple regions of the U.S., years 2000–2002 and 2010–2012.
PARTICIPANTS:
Participants aged 45-84 were followed for 10 years (N=3567).
RESULTS:
Median HEI was 59 at baseline and 62 at follow-up. Residing in areas with a high density of restaurants (highest ranked quartile) was cross-sectionally associated with 52% higher odds of frequently eating restaurant meals (≥3 times/week, odds ratio [OR]: 1.52, 95% confidence interval [CI] 1.18-1.98) and 3% higher odds of having lower dietary quality (HEI lowest quartile<54, OR:1.03, CI: 1.01-1.06). Longitudinal changes were small and associations not sustained. Cross-sectional analysis found 34% higher odds of having lower dietary quality for those who frequently ate at restaurants (OR: 1.34,CI:1.12-1.61); and more restaurant meals (over time increase ≥1 times/week) was associated with higher odds of having worse dietary quality at follow-up (OR: 1.21,CI:1.00-1.46).
CONCLUSIONS:
Restaurant density was associated with frequently eating out in cross-sectional and longitudinal analyses but was associated with lower dietary quality only in cross-sectional analyses. Frequent restaurant meals were negatively related to dietary quality. Interventions that encourage less frequent eating out may improve population dietary quality.
