OBJECTIVE: The aim of this nested case-control study was to compare the effectiveness of cognitive-behavioral treatment (CBT) for treatment-resistant obese (body mass index [BMI] ≥30 kg/m2) women compared with standard dietary treatment. The main outcome measures were attrition and weight loss success. METHODS: We designed a 6-month case-control study, nested within a cohort of adult (age ≥18 years) treatment-resistant (history of at least two previous diet attempts) obese women. Cases were 20 women who were offered CBT sessions. Controls (n=39) were randomly selected from the source population and matched to cases in terms of baseline age, BMI, and number of previous diet attempts. RESULTS: Compared with controls, cases were significantly more likely to complete the 6-month program in both age-adjusted (odds ratio [OR]=2.94, 95% confidence interval [CI]=1.05–8.97) and multivariate-adjusted (OR=2.77, 95% CI=1.02–8.34) analyses. In contrast, cases were not more likely to achieve weight loss success in age-adjusted (OR=1.32, 95% CI=0.86–1.67) and multivariateadjusted (OR=1.21, 95% CI=0.91–1.44) analyses. CONCLUSIONS: Compared with a standard dietary treatment, CBT was significantly more effective in reducing attrition in treatment-resistant obese women, without differences in terms of weight loss success.

Abstract
OBJECTIVE: The aim of this nested case-control study was to compare the effectiveness of cognitive-behavioral treatment (CBT) for treatment-resistant obese (body mass index [BMI] ≥30 kg/m2) women compared with standard dietary treatment. The main outcome measures were attrition and weight loss success. METHODS: We designed a 6-month case-control study, nested within a cohort of adult (age ≥18 years) treatment-resistant (history of at least two previous diet attempts) obese women. Cases were 20 women who were offered CBT sessions. Controls (n=39) were randomly selected from the source population and matched to cases in terms of baseline age, BMI, and number of previous diet attempts. RESULTS: Compared with controls, cases were significantly more likely to complete the 6-month program in both age-adjusted (odds ratio [OR]=2.94, 95% confidence interval [CI]=1.05–8.97) and multivariate-adjusted (OR=2.77, 95% CI=1.02–8.34) analyses. In contrast, cases were not more likely to achieve weight loss success in age-adjusted (OR=1.32, 95% CI=0.86–1.67) and multivariateadjusted (OR=1.21, 95% CI=0.91–1.44) analyses. CONCLUSIONS: Compared with a standard dietary treatment, CBT was significantly more effective in reducing attrition in treatment-resistant obese women, without differences in terms of weight loss success.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
