Background. Obesity has been linked to stress, but there is lack of strong evidence from general populations. %26lt;br%26gt;Methods. 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. %26lt;br%26gt;Results. 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, 135) 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, 135) for women who were extremely stressed compared with women who were not at all stressed. %26lt;br%26gt;Conclusion. Lifetime stress was associated with an increased risk of obesity especially in women.
