Analysis of Drinking Behavior According to Household Type: Using Data from the 6th Korean National Health and Nutrition Examination Survey

BACKGROUND: Previous studies have revealed an association between health behavior and household type; moreover, there have been debates on the relation between drinking behavior and household type. Therefore, we examined drinking behavior of one-person households and compared the differences with multi-person households.METHODS: This study analyzed 8,966 participants, aged 19 years or older, in the 6th Korea National Health and Nutrition Examination Survey (2013, 2015). All participants were categorized into one- and multi-person households. The general characteristics were extracted using a chi-square test, and the risk of drinking behavior of one-person households was analyzed via multiple logistic regression.RESULTS: There were no statistically significant differences in the drinking behavior of men by household type. However, the risks of binge and problem drinking were 3.242 times (95% confidence interval [CI], 1.624–6.471) and 2.488 times (95% CI, 1.097–5.642) higher, respectively, in one-person household women than in multi-person household members aged between 19 and 39 years. Furthermore, the risk of problem drinking was 2.266 times (95% CI, 1.126–4.561) higher in one-person household women than in multi-person household members aged between 40 and 64 years.CONCLUSION: Considering the increasing trend of one-person households, follow-up studies on drinking behavior of one-person households are needed; the findings of these studies need to be used to prevent alcohol-related diseases and socio-economic problems.

Association of Metabolic Syndrome with Whole Milk and Low Fat Milk: Using Data from the Korean National Health and Nutrition Examination Survey 2013–2015

BACKGROUND: Korean milk consumption and low-fat milk sales are steadily increasing. The purpose of this study was to examine the association of metabolic syndrome according to the type of milk. METHODS: The subjects included 5,553 persons who aged 19 to 64 years, from the data of the Korea National Health and Nutrition Examination Survey (KNHANES) 2013–2015. All subjects were divided by intake of type of milk that are ‘whole milk intake group’, ‘low-fat milk intake group’ and ‘no milk intake grou’p. And the subects were classified as 19-39 years old and 40-64 years old. In order to check differences of demo-sociographic characteristics and metabolic risk factors in three groups, the data was analyzed by chi-square test, t-test and binary logistic regression analysis. RESULTS: For subjects aged 40–64, whole milk intake group had lower relevance with metabolic syndrome than no milk intake group (odds ratio [OR] 0.807, P=0.035, 95% confidence interval [CI] 0.660–0.985). But low fat milk intake group was't relevant (OR 0.879, P=0.350, 95% CI 0.670–1.152). Looking at the 19-39 year-old subjects, whole milk and low fat milk intake group were not associated with metaboic syndrome (OR 1.023, P=0.911, 95% CI 0.686–1.525; OR 1.547, P=0.103, 95% CI 0.915–2.617). CONCLUSIONS: The results of this study show that whole milk intake is less relevant to the metabolic syndrome than no milk intake. Low fat milk intake was not relevant. More researches are needed to determine the effects of low fat milk and whole milk on metabolic syndrome.
