Earnings and work loss from 5 years before to 5 years after bariatric surgery: A cohort study

BackgroundThe personal economic impact of bariatric surgery is not well-described. ObjectivesTo examine earnings and work loss from 5 years before to 5 years after bariatric surgery compared with the general population. SettingNationwide matched cohort study in the Swedish health care system. MethodsPatients undergoing primary bariatric surgery (n = 15,828) and an equal number of comparators from the Swedish general population were identified and matched on age, sex, place of residence, and educational level. Annual taxable earnings (primary outcome) and annual work loss (secondary outcome combining months with sick leave and disability pension) were retrieved from Statistics Sweden. Participants were included in the analysis until the year of study end, emigration or death. ResultsFrom 5 years before to 5 years after bariatric surgery, earnings increased for patients overall and in subgroups defined by education level and sex, while work loss remained relatively constant. Bariatric patients and matched comparators from the general population increased their earnings in a near parallel fashion, from 5 years before (mean difference -$3,489 [95%CI -3,918 to -3,060]) to 5 years after surgery (-$4,164 [-4,709 to -3,619]). Work loss was relatively stable within both groups but with large absolute differences both at 5 years before (1.09 months, [95%CI 1.01 to 1.17]) and 5 years after surgery (1.25 months, [1.11 to 1.40]). ConclusionsFive years after treatment, bariatric surgery had not reduced the gap in earnings and work loss between surgery patients and matched comparators from the general population.

Automated summary

This study examined the economic impact of bariatric surgery on earnings and work loss. The results showed that patients experienced an increase in earnings after surgery, but work loss remained relatively constant. There was still a gap in earnings and work loss between bariatric surgery patients and the general population.
