BODY-Q
The BODY-Q is the best validated questionnaire for evaluating QoL and appearance in (post-) bariatric patients and was added as a PROM in our modified screenings tool 26. The questionnaire consists of 18 scales divided in three domains: QoL, appear- ance and patient experience 27. It has shown good validity and reliability (test-re-test reliability r=0.87 for 17 of 18 scales; internal consistency, Cronbach α=0.90 for 18 of 18 scales) 27. For the purpose of this study we used all scales of the QoL domain (body image, physical function, psychological function, sexual function, social func- tion, obesity-specific physical symptoms) and five scales of the appearance domain (appraisal of excess skin, satisfaction with abdomen, arms, hips and breasts). Scores for each scale ranges from 0-100; higher scores indicate more positive results.
Statistical analysis
Descriptive statistics were used to summarize baseline characteristics and weight change of the studied patient population. Included patients were divided in two groups: patients who wanted BCS and patients who did not want BCS. Baseline char- acteristics, questionnaire scores and BODY-Q score were compared between these groups. Correlations between the BODY-Q and screeningtool questions were studied with Pearson’s correlations. Subsequently patients who wanted BCS and qualified for referral (score ≥ 8) were compared to patients who wanted BCS and did not qual- ify (score ≤ 7). Continuous variables were compared using independent t-tests; for dichotomous data chi-square or fishers’ exact tests were used. Findings were con- sidered statistically significant if the p-value was < 0.05. All analyses were performed using SPSS, version 23 (IBM Corp. Released 2015. IBM SPSS Statistics for Windows, Version 23.0. Armonk, NY: IBM Corp.).
RESULTS
Study population
Invitations for the study were sent out to 168 patients; 120 patients (71%) responded, signed informed consent and were included in this study. Age, BMI before bariat- ric surgery, current BMI, %TWL and follow-up time did not significantly differ when comparing responders and non-responders. In the non-responder group there were significant less females (73% versus 90%, p=0.011).
Mean age of the included population was 46 years; 90% was female. Patients had a mean BMI of 44.2 kg/m2 (range 27.1 to 65.6 kg/m2) before bariatric surgery. Most patients underwent a primary Roux-en-y Gastric Bypass (83.3%). Follow-up was 2 years in 86 patients and 3 years in 34 patients. Mean current BMI was 30.8 kg/m2 and current TWL was 29.9%; 78 patients (65.0%) met the Dutch weight criteria (stable weight and BMI < 35 kg/m2).
