Abstract:
PURPOSE: The aim of this study was to examine associations between marital status and vegetable intake. METHODS: Data were from participants 30 years and over (n = 18,190) in the 2007~2010 Korea National Health and Nutrition Examination Survey. Marital status was divided into three groups: married, never married, and separated/divorced/widowed. Vegetable intake was estimated from the twenty-four hour dietary recall. Data were analyzed using a chi-square test, analysis of covariance, least squares means, and logistic regression. RESULTS: Married respondents tend to consume more vegetables, including kimchi, than all other marital status groups. Vegetable intake, excluding kimchi, was lowest among 30~64 year-old respondents who had never married. Elderly men (65 years and older) who were never married/separated/divorced/widowed had significantly lower vegetable intake than elderly men who were married (p = 0.0008). When considering the Korean dietary reference intake (KDRIs), elderly men who were never married/separated/divorced/widowed, compared with elderly men who were married, had a significantly higher odds ratio for consuming fewer vegetables than the KDRIs (OR = 1.64, 95% CI: 1.13~2.37). CONCLUSION: The findings of this study indicate that marital status might influence vegetable intake and the probability of consuming fewer vegetables than the KDRIs. In particular, being never married/separated/divorced/widowed might adversely affect vegetable consumption among elderly men, although assessing the causal effect of marital status from this cross-sectional study is difficult.
