ABSTRACT
BACKGROUND: Underweight refers to the weight range in which health risk can increase, since the weight is lower than a healthy weight. Negative attitudes towards obesity and socio-cultural preference for thinness could induce even underweight persons to attempt weight control. This study was conducted to investigate factors related to weight control attempts in underweight Korean adults. METHODS: This was a cross-sectional study on 690 underweight adults aged 25 to 69 years using data from the Korea National Health and Nutrition Examination Survey, 2007-2010. Body image perception, weight control attempts during the past one year, various health behaviors, history of chronic diseases, and socioeconomic status were surveyed. RESULTS: Underweight women had a higher rate of weight control attempts than underweight men (25.4% vs. 8.1%, P < 0.001). Among underweight men, subjects with the highest physical activity level (odds ratio [OR], 7.75), subjects with physician-diagnosed history of chronic diseases (OR, 7.70), and subjects with non-manual jobs or other jobs (OR, 6.22; 12.39 with reference to manual workers) had a higher likelihood of weight control attempts. Among underweight women, subjects who did not perceive themselves as thin (OR, 4.71), subjects with the highest household income level (OR, 2.61), and unmarried subjects (OR, 2.08) had a higher likelihood of weight control attempts. CONCLUSION: This study shows that numbers of underweight Korean adults have tried to control weight, especially women. Seeing that there are gender differences in factors related to weight control attempts in underweight adults, gender should be considered in helping underweight adults to maintain a healthy weight.

BACKGROUND: Marital status is not only an important sociodemographic variable for health studies but influences health behavior and health condition of individuals. This study assessed a representative sample to see whether marital status is associated with health behavior in middle-aged Korean adults, and if the association differed by sex. METHODS: This is a cross-sectional study of 9,535 Korean middle-aged adults who participated in the 2007-2010 Korean National Health and Nutrition Examination Survey. Our data were from this survey. The subjects were classified as married and living with a partner, widowed, separated/divorced, or never married. We assessed the relationship between marital status and five health behaviors (smoking, high risk alcohol intake, regular exercise, regular breakfast consumption, and periodic health screening) after controlling covariates. RESULTS: In men, the separated/divorced group had a higher risk for high risk alcohol consumption (odds ratio [OR], 1.52; 95% confidence interval [CI], 1.05-2.19) and lower tendencies to have breakfast regularly (OR, 0.44; 95% CI, 0.29-0.67) and to undergo health screening (OR, 0.54; 95% CI, 0.37-0.79) than the married and living with a partner group while men were more likely to exercise regularly (OR, 1.81; 95% CI, 1.13-2.88). In women, both of the separated/divorced group and had a significantly higher risk for smoking and high risk alcohol consumption than married and living with a partner group by 3-6 times. The separated/divorced women group was less likely to have breakfast regularly (OR, 0.55; 95% CI, 0.41-0.74). Significant interactions between sex and marital status were observed with smoking (P<0.001), high risk alcohol intake (P<0.001), regular breakfast consumption (P<0.001), and periodic health screening (P=0.003). CONCLUSIONS: The association between marital status and health behaviors differed by sex. Even in the single group, differences were seen according to the subtypes of the single group.

BACKGROUND: Marital status is as an important sociodemographic variable for health studies. We assessed the association between marital status and health behavior in middle-aged Korean adults. METHODS: This is a cross-sectional study of 2,522 Korean middle-aged adults (1,049 men, 1,473 women) from the 2010 Korean National Health and Nutrition Examination Survey. The subjects were classified as living with a partner or living without a partner (never married, separated, widowed, and divorced). We assessed the relationship between marital status and five health behaviors (smoking, high-risk alcohol intake, regular exercise, regular breakfast consumption, and undergoing periodic health screening). RESULTS: Age, income level, educational level, and occupational classification were all significantly associated with marital status. The risk of undergoing health screening (odds ratio [OR], 0.53; 95% confidence interval [CI], 0.32 to 0.90) and having regular breakfast (OR, 0.50; 95% CI, 0.27 to 0.92) were significantly lower in men living without a partner than with a partner. Women living without a partner had a higher smoking risk (OR, 2.27; 95% CI, 1.09 to 4.73) and a higher risk of high-risk alcohol consumption (OR, 5.33; 95% CI, 1.65 to 17.24) than their counterparts. CONCLUSION: Korean middle-aged adults living with partners are more likely to have healthier behavior than living without a partner. The association between marital status and health behaviors differed by sex.
