The results of analyzing the fit of the three candidate conceptual models yielded other intriguing results. Model 1 did not fit the data well. It explained 11% of the variance in obesity. The poor fit of the model was indicated by discrepancy, χ2(5)=15.3, p=.009, and RMSEA, RMSEA=.114, pclose=.046, indices that were statistically significant and an AGFI of 0.89, which is less than the desired minimum of 0.90. Importantly, an examination of the structural paths within Model 1 indicated no significant association between depression symptoms and obesity (β=.04, p=.64). Obesity was, however, significantly associated with CD4+cell count, protease inhibitor use, and the number of symptoms of stimulant dependence (Figure 2).
