PHQ-9 = Patient Health Questionnaire. For each treatment group n = 15 at baseline and n = 13 at Week 12. Data are reported as mean ± SD.
a p values at least .05 for all variables when comparing health education and exercise interventions on the baseline assessment using a two sample t test.
bAnalysis of covariance assessing change in measures. For these analyses, the week 12 assessment was the dependent variable and treatment group and the baseline assessment were the independent variables.
cVolume of oxygen consumed in milliliters of oxygen per kilogram of body weight per minute.
