OBJECTIVES: We compared the health-related quality of life (HRQoL) of people with obesity (PwO) who have and have not received bariatric surgery (BS) and the general population in Singapore.
METHODS: We analysed three groups of individuals. The first comprised 1769 local adults who completed EQ-5D-5L during a nationwide household survey. The second and third comprised 112 non-BS and 110 post-BS patients recruited from local hospital weight management clinics. Non-BS patients had BMI ≥37.5 kg/m2 or BMI ≥32.5 kg/m2 with an obesity-related condition. All post-BS patients received BS ≥6 months ago. Both non-BS and post-BS patients completed EQ-5D-5L core (Mobility-MO, Self-care-SC, Usual activities-UA, Pain/Discomfort-PD, Anxiety/Depression-AD) and additional dimensions (Breathing-BR, Sleep-SL, Tiredness-TI, Appearance-PA, Intimacy-IN, Discrimination/Humiliation-DH, Social-SA, Self-confidence-CO, Burden to others-BU, Diet Control-DC, Food Enjoyment-FE, Gastrointestinal problems-GI) and eight BODY-Q subscales: Physical Function-PhyF, Physical Symptoms-PhyS, Psychological Function-PsyF, Social Function-SocF, Eating Behaviour-EatB; Body Image-BodyI, Appearance Distress-AppearD, Sexual Function-SexualF). Differences in EQ-5D-5L and bolt-on dimensions (No problem/Have problem) and EQ-5D-5L Index, EQ VAS, and BODY-Q subscale scores between the BS patients and non-BS patients/general population members were examined using logistic or linear regression models, with adjustment for age, gender, and ethnicity.
RESULTS: Post-BS participants were significantly (p<0.05) less likely to report problems in UA (OR: 0.40), PA (OR: 0.38), DC (0.48) and had better EQ VAS (β: 13.91), PhyF (β: 7.40), PhyS (β: 5.03), EatB (β: 4.64), BodyI (β: 9.04) and AppearD (β: -7.24) scores than non-BS. However, post-BS participants were significantly more likely to experience problems with FE (OR: 4.63) and GI (4.64) than non-BS. Comparing to the general population, post-BS participants were significantly morelikely to report problems in MO (OR: 2.35) and had poorer VAS (β: -4.07).
CONCLUSIONS: While post-BS participants had slightly poorer HRQoL than the general population, their HRQoL was significantly better than non-BS PwO, suggesting potential values of BS in improving HRQoL.
