Korea has the highest suicide rate in the OECD and is one of the few OECD countries whose suicide rates have not decreased in recent years. To address these issues, we investigated the effects of weight control failure on suicidal ideation in the overweight and obese populations.
We performed a cross-sectional study using data from the Korea National Health and Nutrition Examination Survey (2008-2012) consisting of 6621 individuals 40 years of age or older. Logistic regression analysis was used to identify the relationship between weight control failure and suicidal ideation in the overweight and obese populations.
A total of 6621 participants were analyzed in this study (overweight group: 2439; obese group: 4182). Among them, weight control failure (weight gain with weight loss efforts) was experienced in 962 obese (males 16.3%, females 29.6%) and 412 overweight individuals (males 9.1%, females 23.4%). Weight control failure was significantly associated with suicidal ideation in obese females (OR = 1.70, 95% CI 1.21-2.39), but this association was not significant in obese males or in either sex of the overweight group.
Findings from this study suggest that weight control failure is associated with an increased risk of suicidal ideation among obese women. Furthermore, intervention programs that aim to address the prevalence of suicide, especially for obese women, are needed.
韩国是经合组织（OECD）成员国中自杀率最高的国家之一，也是近年来自杀率未下降的少数几个经合组织国家之一。为解决这些问题，我们调查了体重控制失败对超重和肥胖人群自杀意念的影响。
我们利用韩国国家健康与营养检查调查（2008 - 2012年）的数据进行了一项横断面研究，该调查涵盖了6621名40岁及以上的个体。采用逻辑回归分析来确定超重和肥胖人群中体重控制失败与自杀意念之间的关系。
本研究共分析了6621名参与者（超重组：2439人；肥胖组：4182人）。其中，962名肥胖者（男性16.3%，女性29.6%）和412名超重者（男性9.1%，女性23.4%）经历了体重控制失败（在努力减肥的情况下体重增加）。体重控制失败与肥胖女性的自杀意念显著相关（OR = 1.70，95% CI 1.21 - 2.39），但在肥胖男性或超重组的任何性别中，这种关联并不显著。
本研究结果表明，体重控制失败与肥胖女性自杀意念风险增加有关。此外，需要开展旨在解决自杀流行问题的干预项目，尤其是针对肥胖女性的项目。
