Background: Both obesity and underweight had been reputed to be related with health risk. However, little was known about the relationship between suicidal ideation and weight loss attempt. This study was conducted to find an association between suicidal ideation and weight loss attempt in underweight adults.

Methods: This was cross-sectional study on 1122 underweight adults (age 19 to 69 years) of Korea National Health and Nutrition Examination Survey, 2007-2012. We examined suicidal ideation, depression diagnosed by doctor, depressive mood, physical activity, health-related behavior, comorbidity, and socioeconomic status. We performed logistic regression analysis to divide by weight loss attempt.

Results: There were 101 subjects in attempt-group and 1021 non-attempt. The attempt-group had higher OR of suicidal ideation (2.47, 95% CI : 1.35-4.53) after adjustment for age, sex, physical activity, alcohol problem, marital status, education, income, occupation, self perception of body image, chronic disease, and BMI. And adjusted OR of suicidal ideation with depressive symptoms added was also significant (2.11, 95% CI : 1.03-4.35). The difference between two groups in depression diagnosed by doctor was not significant (0.36 95% CI : 0.65-1.73).

Conclusion: Weight loss attempt itself even underweight was associated with suicidal ideation in Korean adults.
