title: Depressive symptoms, diet quality, physical activity, and body composition among populations in Nova Scotia, Canada: report from the Atlantic Partnership for Tomorrow's Health.
abstract: OBJECTIVE
  To investigate the association between depressive symptoms and diet quality, physical activity, and body composition among Nova Scotians.
  
  
  METHODS
  4511 men and women aged 35-69 years were recruited to the Atlantic Partnership for Tomorrow's Health study from 2009 through 2010 in Nova Scotia, Canada. Depressive symptoms were assessed by using the Patient Health Questionnaire. Anthropometric indexes and body composition were measured. Current antidepressant use, habitual diet intake, physical activity, and potential confounders were collected through questionnaires.
  
  
  RESULTS
  In multivariable regression analyses, depressive symptoms were positively associated with all obese indexes after controlling for potential confounders (all P for trend<0.001). Compared with non-depressed individuals, those with mild and major depression had significantly increased odds ratios (ORs) for both obesity and abdominal obesity (OR 1.84; 95% confidence interval [CI], (1.50, 2.25) and 1.56 (95% CI, 1.30, 1.87) for obesity and 1.46 (95% CI, 1.20, 1.77) and 1.88 (95% CI, 1.58, 2.24) for abdominal obesity, respectively). Depressed individuals were less likely to have a high quality diet or engage in high levels of physical activity compared with their non-depressed counterparts.
  
  
  CONCLUSIONS
  Depressive symptoms are associated with higher levels of obesity, poor diet, and physical inactivity among Nova Scotians in Canada.
