Obesity has been linked to stress, but there is lack of strong evidence from general populations.
The analysis was based on data from 112,716 Canadians aged 18 years or more who participated in a national survey conducted in 2007-2008. A questionnaire covered the information on self-perceived lifetime stress, height, and weight. Logistic regression analysis was used to determine the association between chronic stress and obesity.
The crude prevalence of obesity was 18.1% for men and 16.0% for women. A small proportion (3.7%) of the participants reported being extremely stressed most days in their lives and 19.1% reported being quite a bit stressed, and the proportions of stress were slightly higher in women than in men. Overall, those who reported being extremely stressed (adjusted OR: 1.23, 95% CI: 1.13, 1.35) or those who reported being quite a bit stressed (adjusted OR: 1.08, 95% CI: 1.02, 1.15) had an increased risk of obesity compared with who were not at all stressed. The adjusted odds ratio was 1.44 (95% CI: 1.13, 1.35) for women who were extremely stressed compared with women who were not at all stressed.
Lifetime stress was associated with an increased risk of obesity especially in women.
肥胖与压力有关，但一般人群缺乏强有力的证据。
该分析基于 2007-2008 年进行的一项全国性调查中 112716 名年龄在 18 岁及以上的加拿大成年人的数据。问卷涵盖了自我感知的终身压力、身高和体重信息。使用逻辑回归分析来确定慢性压力与肥胖之间的关联。
男性肥胖的粗患病率为 18.1%，女性为 16.0%。一小部分（3.7%）参与者报告称，他们一生中大部分时间都感到极度压力，19.1%的参与者报告称他们感到相当大的压力，女性的压力比例略高于男性。总的来说，与那些没有压力的人相比，报告感到极度压力（调整后的 OR：1.23，95%CI：1.13，1.35）或报告感到相当大压力（调整后的 OR：1.08，95%CI：1.02，1.15）的人肥胖的风险增加。与没有压力的女性相比，压力极大的女性的调整后比值比为 1.44（95%CI：1.13，1.35）。
终身压力与肥胖风险增加有关，尤其是在女性中。
