Ba ckground: Being underweight has been related to health risks. However, little is known about therelationship between suicidal ideation and attempting to lose weight. This study was conducted toexamine if there is an association between suicidal ideation and attempting to lose weight amongunderweight adults. Me thods: A cross-sectional study of 1,122 underweight adults (range, 19 to 69 years) was conducted basedon the Korea National Health and Nutrition Examination Survey, 2007–2012. We examined suicidalideation, doctor-diagnosed depression, depressive mood, stress, physical activity, health-related behavior,comorbidity, and socioeconomic status by weight loss attempts. Logistic regression analysis wasperformed to examine the association between suicidal ideation and weight loss attempts. The followingcovariates were controlled for: age, sex, physical activity, alcohol problem, marital status, education,income, occupation, self-perception of body image, chronic disease, and body mass index. Re sults: There were 101 subjects in the weight loss attempt group and 1,021 in the non-attempt group. Theattempt group had a higher risk of suicidal ideation (odds ratio [OR], 2.47; 95% confidence interval [CI],1.35 to 4.53) and depressive symptoms (OR, 2.17; 95% CI, 1.19 to 3.98). After depressive symptomswere added to the covariates, the risk of suicidal ideation was also significant (OR 2.11, 95% CI: 1.03 to4.35). The two groups did not significantly differ in doctor-diagnosed depression and stress. Co nclusion: Weight loss attempts were associated with suicidal ideation in underweight Korean adults.
