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.

본 연구는 30세 이상 한국성인의 결혼상태와 채소섭취와의 연관성을 분석하고자 하였다. 이를 위해 2007~2010년 국민건강영양조사 자료를 이용하여 조사 참가자의 성별, 연령대별 채소섭취량을 비교하고, 채소를 권장섭취횟수보다 부족하게 섭취할 위험도를 분석하였다. 분석결과, 결혼상태에 따라 성별, 연령대별 채소섭취량에 차이가 있었다. 남녀 모두 유배우자 동거 집단의 김치를 포함한 채소섭취량이 결혼한 적 없는 집단과 별거/이혼/사별 집단과 비교해 가장 높았다. 김치를 포함한 채소를 권장섭취횟수보다 적게 섭취할 위험도는 유배우자 동거집단에 비해 결혼한 적 없거나 별거/이혼/사별인 경우 높아지는 경향을 보였다. 65세 이상 남자의 경우 결혼한 적 없음/별거/이혼/사별 집단은 유배우자 동거 집단과 비교해 채소섭취량이 낮았으며, 채소를 권장섭취횟수보다 적게 섭취할 위험도는 높았다. 결혼상태와 채소섭취량의 관계를 명확히 파악하기 위해서는 결혼상태와 식생활의 변화를 함께 조사할 수 있는 코호트 연구가 수행돼야 한다. 또한 결혼상태의 지속기간, 결혼상태의 만족도 등 결혼상태를 다양하게 파악할 수 있는 정보와 함께, 식생활 상태를 평가할 수 있는 자료를 수집해야 한다.
