- Cross-cultural translation and validation to Portuguese of the bariatric quality of life (BQL) IndexPublication . Figueiredo, Inês Rego de; Carvalho, Miguel Vasques; Cunha, Nelson; Martins, Diana; Silva-Nunes, JoséIntroduction: Obesity is a chronic noncommunicable disease, defined by the body mass index (BMI) ≥ 30Kg/m2. Its burden is not restricted to mortality and morbidity from other noncommunicable diseases, but also from a decrease in quality of life (QoL). There are several tools for assessing QoL, from generic health-related tools to obesity-related tools. However, to assess QoL in patients undergoing bariatric surgery there was only BAROS, which has some issues. Therefore, the Bariatric Quality of Life (BQL) index was developed. We aimed to perform a cross-cultural adaptation and validation of the BQL index in the Portuguese language. Methods: A cross-sectional study was performed, by presenting two questionnaires to participants: BQL índex and EQ-5D-3L. Translation followed by forward translation, reviewing, back-translation, comparison, and pilot testing was done. A retest was performed 6 months after the baseline. The following psychometric properties were assessed: converging validity by correlation through Spearman coefficient (r>0.3) of BQL and EQ-5D-3L, internal consistency by Cronbach alfa coefficient (≥0.5), and reproducibility between test and retest through Spearman correlation (r>0.3) and intraclass correlation coefficient (≥ 0.60). Results: A total of 260 participants were included, the majority (78%) being females, mean age of 45±10 years old, and a mean BMI of 44±6.5kg/m2. The most common obesity-related conditions were osteoarticular disease (69%), anxiety/depression (60%), and hypertension (54%); the eating patterns were volume-eater (67%) and sweet-eater (62%). QoL scores were 41.3±9.3 for the BQL index, 0.35±0.19 for the EQ-5D-3L index, and 55.7±19.8 for the EQ-5D-3L VAS. The translation yielded good convergent validity (r=0.62), good internal consistency (a=0.94), and good reproducibility (r=0.62 and ICC=0.79). Conclusions: Our translation exhibited good parametric properties, with validity within the original BQL values, higher internal consistency, and suboptimal reproducibility. We can conclude that this version of the BQL index is suitable for Portuguese patients.
- Psychopathological and quality of life gender differences in obese patients who were candidates for bariatric surgeryPublication . Figueiredo, Inês Rego de; Carvalho, Miguel Vasques; Cunha, Nelson; Martins, Diana; Silva-Nunes, JoséIntroduction: Gender differences in obesity go from prevalence, access to treatment, baseline characteristics, outcomes, and complications. Our aim was to access baseline differences in a bariatric surgery cohort, with an emphasis on psychopathology and quality of life (QoL). Methodology: Cross-sectional study at a bariatric surgery clinic performed by application of psychological (Y-BOCS, HAD scale, FCQ-S/T, BIS-11), and QoL (EQ-5D-3L and BQL index) questionnaires. Demographic, anthropometric, and comorbidities data was collected, as well as eating patterns, and motivation for surgery. A comparison between female and male patients was performed. Results: 244 patients were included, with similar age distribution between males (n=55) and females (n=189). Males had higher visceral fat (12.6±2.8% vs. 22.6±4.4%; p<0.001) and waist circumference (129±13cm vs. 135±14cm; p=0.02), lower total fat mass (52±4% vs. 38±4%; p<0.001), but with similar BMIs (44±5.8kg/m2 vs. 45±7.6kg/m2 ; p=ns). Hypertension, sleep apnea, and liver steatosis were more frequent in men, depression/anxiety, and venous insufficiency in women; diabetes, dyslipidemia, and osteoarticular disease were similar. Men engaged more in volume eating and females in emotional eating. Among women, issues with body image were the most usual motivation for surgery. The psychopathological profile showed a higher prevalence of anxiety in women (41% vs. 19%, p=0.02). Obsessive-compulsive traits, depression, food cravings, and impulsivity were similar. No gender differences were observed for QoL in the EQ5D-3L index and VAS and BQL index. However, there were differences in the following EQ-5D-3L health profiles of usual activities (p=0.03), pain/discomfort (p=0.001), and anxiety/depression (p<0.001). Conclusions: Although some comorbidities are more common in male obese patients, they are a minority in the bariatric surgery setting. A difference is present between male and female patients in eating patterns and motivation for surgery, inducing a psychological profile characterized by higher anxiety prevalence. This greater prevalence impacts in QoL, contributing to a higher burden of obesity among obese women.
