Background
The relationship between diet quality and health care costs is unclear. Objective The aim of this study was to investigate the relationship between baseline diet quality and change in diet quality over time, with 15-year cumulative health care claims/costs. Design Data from a longitudinal cohort study were analyzed. Participants/setting Data for survey 3 (2001) (n = 7,868) and survey 7 (2013) (n = 6,349 both time points) from the 1946-1951 cohort of the Australian Longitudinal Study on Womens Health were analyzed. Main outcome measures Diet quality was assessed using the Australian Recommended Food Score (ARFS). Fifteen-year cumulative Medicare Benefits Schedule (Australias universal health care coverage) data were reported by baseline ARFS quintile and category of diet quality change (diet quality worsened [ARFS change ≤ 4 points], remained stable [3 ≤ change in ARFS ≤3 points], or improved [ARFS change ≥4 points]). Statistical analyses Linear regression analyses were conducted adjusting for area of residence, socioeconomic status, lifestyle factors, and private health insurance status. Results Consuming a greater variety of vegetables at baseline but fewer fruit and dairy products was associated with lower health care costs. For every 1-point increment in the ARFS vegetable subscale, women made 3.3 (95% CI, 1.6-5.0) fewer claims and incurred AU$227 (95% CI, AU$104-350 [US$158; 95% CI, US$72-243]) less in costs. Women whose diet quality worsened over time made more claims (median, 251 claims; quintile 1, quintile 3 [Q1; Q3], 168; 368 claims) and incurred higher costs (AU$15,519; Q1; Q3, AU$9,226; AU$24,847 [US$10,793; Q1; Q3, US$6,417; US$17,281]) compared with those whose diet quality remained stable (median, 236 claims [Q1; Q3, 158; 346 claims], AU$14,515; Q1; Q3, AU$8,539; AU$23,378 [US$10,095; Q1; Q3, US$5,939; US$16,259]). Conclusions Greater vegetable variety was associated with fewer health care claims and costs; however, this trend was not consistent across other subscales. Worsening diet quality over 12 years was linked with higher health care claims and costs. |
