Abstract
BACKGROUND: Massive weight loss (MWL) patients who undergo body contouring plastic surgery (BCPS) display superior long-term weight maintenance. The effect of the number of anatomical areas contoured on weight dynamics is undetermined. OBJECTIVES: To determine whether body mass index (BMI) dynamics following BCPS are associated with the number of anatomical areas operated. METHODS: A retrospective cohort study was conducted. Study groups were defined by the number of anatomical areas operated (1, 2, and 3+). BMI velocity was defined as a ratio between BMI change following BCPS and follow-up time. Multinomial logistic regression was performed to assess the independent association with BMI velocity. RESULTS: A total of 222 patients undergoing 513 BCPSs between 2009 and 2014 were included in the study (mean age 36.8 ± 10.9 years, 77% females). Group 3+ (n = 88) had a negative mean BMI velocity compared with positive values in Groups 1 and 2 (-0.11 ± 1.0 vs. 0.44 ± 1.4 and 0.03 ± 1.2, respectively; p = 0.03). Independent risk factors for positive BMI velocity (>0.5 kg/m2/year) included single anatomical area BCPS compared to three or more (OR = 3.37; CI 95% 1.24-9.14; p = 0.017) and psychiatric medication use (OR = 6.73; CI 95% 1.15-39.35; p = 0.034). Independent protective factors included diabetes mellitus (OR = 0.094; CI 95% 0.01-0.99; p = 0.049). CONCLUSIONS: BCPS in three or more anatomical areas following MWL is associated with a long-term weight loss following BCPS. As part of the health strategy to maintain normal BMI values and achieve overall quality of life improvement in MWL patients, clinicians and health policy makers should positively consider recommending BCPS in multiple anatomical areas.
