Identifying predictive variables for long-term weight change after participation in a weight loss program

In the investigation of whether there was an association between weight change and 31 independent variables among obese persons 2 years after a weight loss program, conducted by Marshall University School of Medicine,(1) found that Of the 31 independent variables, 16 were significantly predictive of weight change. The adjusted R2 for the entire group of 16 variables was .379. Thus, 37.9% of the variance was explained by the joint efforts of the 16 variables. Eight variables with an adjusted R2 of .371 (accounting for 37.1% of the variance) were most important: feeling in control of eating habits, percentage over ideal body weight at enrollment, percentage of weight lost during the 8-week treatment, frequency of weight measurement, increase in physical activity, frequency of eating in response to emotions, number of pounds gained before subject resumed diet, and occupation
