Abstract

BACKGROUND: Psychological well-being is associated with longevity and reduced risk of disease, but possible mechanisms are understudied. Health behaviors like eating fruits and vegetables may link psychological well-being with better health; however, most evidence is cross-sectional. PURPOSE: This study investigated psychological well-being's longitudinal association with fruit and vegetable consumption across as many as 7 years. METHOD: Participants were 6,565 older adults from the English Longitudinal Study of Ageing, which includes men and women aged 50 years or older. Psychological well-being was assessed with 17 items from the Control, Autonomy, Satisfaction, Pleasure Scale. Fruit and vegetable consumption was initially assessed during 2006-2007 and then approximately every 2 years through 2012-2013. Covariates included sociodemographic factors, health status, and other health behaviors. RESULTS: Mixed linear models showed that higher baseline levels of psychological well-being were associated with more fruit and vegetable consumption at baseline (β = 0.05, 95% confidence interval [CI] [0.02, 0.08]) and that fruit and vegetable consumption declined across time (β = -0.01, 95% CI [-0.02, -0.004]). Psychological well-being interacted significantly with time such that individuals with higher baseline psychological well-being had slower declines in fruit and vegetable consumption (β = 0.01, 95% CI [0.01, 0.02]). Among individuals who initially met recommendations to consume 5 or more servings of fruits and vegetables (N = 1,719), higher baseline psychological well-being was associated with 11% reduced risk of falling below recommended levels during follow-up (hazard ratio = 0.89, 95% CI [0.83, 0.95]). CONCLUSIONS: Findings suggest that psychological well-being may be a precursor to healthy behaviors such as eating a diet rich in fruits and vegetables. (PsycINFO Database Record

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
