Longitudinal associations between psychological well-being and the consumption of fruits and vegetables.

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 (? = 0.05, 95% confidence interval [CI] [0.02, 0.08]) and that fruit and vegetable consumption declined across time (? = -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 (? = 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

Project description:BackgroundOne important aspect of subjective judgments about one's well-being (i.e., subjective well-being: life satisfaction, positive affect, and negative affect) is that cultural features, such as, nationality seem to shape cognitive judgments about the "the ideal life." In this comparative study we examined differences in subjective well-being and psychological well-being between Italian and Swedish adolescents and tested if the relationship between the three constructs of subjective well-being (i.e., satisfaction with life, positive affect, and negative affect) and psychological well-being was moderated by the adolescents' nationality.MethodItalian (n = 255) and Swedish (n = 277) adolescents answered to the Satisfaction with Life Scale, the Positive Affect Negative Affect Schedule, and Ryff's Scales of Psychological Well-Being. Differences between samples were tested using a Multiple Analysis of Variance. We also conducted a multiple group analysis (Italy and Sweden) using Structural Equation Modelling to investigate the relationship between all three subjective well-being constructs and psychological well-being.ResultsItalian adolescents scored significantly higher in satisfaction with life than Swedish adolescents. Additionally, across countries, girls scored significantly higher in negative affect than boys. In both countries, all three constructs of subjective well-being were significantly associated to adolescents' psychological well-being. Nevertheless, while the effect of the relationship between affect and psychological well-being was almost the same across countries, life satisfaction was more strongly related to psychological well-being among Swedish adolescents.ConclusionsThe present study shows that there are larger variations between these two cultures in the cognitive construct of subjective well-being than in the affective construct. Accordingly, associations between the cognitive component, not the affective component, of subjective well-being and psychological well-being differ between countries as well.
