TORRESANI, M et al. Perception of adherence to treatment and decrease in body weight among adult women with overweight and obesity. Diaeta [online]. 2011, vol.29, n.137, pp. 31-38. ISSN 1852-7337.
Introduction: The real effectiveness of treatments for obesity depends on how adherent the patient is. Objectives: To estimate the correlation between the decrease in body weight and perception of adherence to treatment among adult women with overweight and obesity Methodology: Experimental design of monitoring. A convenience non-probability sampling of 112 women over 20 years with BMI ≥ 25 kg/m2, who attended the nutritional consultation at the Foundation for the Endocrine and Metabolic Disease Research of the Autonomous City of Buenos Aires, within UBACyT Project 2010 - 2012. Dependent variable: change in body weight (expressed in % per week and categorized in <1% and ≥ 1%) between initial consultation and first control. Independent variable: perception of adherence to treatment (expressed in % of compliance with food plans and scheduled physical activity), on a scale of 0 to 100 and categorized into three ranges:≤ 50%, 60 to 70% and> 70%. Monitoring was carried out taking into account overweight level (BMI 25.0 to 29.9, from 30 to 34.9 and≥ 35 kg/m2), age (<40, 40 to 65 and> 65 years) and time between initial visit and control (2, 3 or 4 weeks at the discretion of the patient). We used SPSS 15.0 establishing measures of central tendency, X2, Fisher's exact test and Spearman correlation p value <0.05. Results: The perception of adherence to treatment self-reported by patients was of 74 ± 12%. 47.3% reported an adherence over 70%, while a 46.4% reported an adherence between 60 and 70%. Direct relationship was found between weekly weight loss and the perception of adherence (r = 0.351, p< 0,001). There was no association between perception of adherence and age ranges, overweight or obesity and the time between the initial visit and the first control. Conclusions: The greater the perception of adherence to treatment, the greater the weight loss per week, having no association with age, BMI, or the time until the first control.
