Abstract

Background

Little is known about the relationship between weight gain during treatment and the subsequent risk of cardiovascular and metabolic (cardiometabolic) diseases. We assessed the relationship between changes in body mass index (BMI) during tuberculosis (TB) treatment and prevalence of post-TB metabolic syndrome, a strong predictor of cardiometabolic diseases.Methods

We enrolled a prospective cohort of individuals successfully treated for TB disease in Tbilisi, Georgia, from 2019 to 2022. Eligible participants were HIV-negative individuals aged ≥16 years with newly diagnosed and laboratory-confirmed pulmonary TB. The primary exposure was relative change in BMI from treatment initiation to treatment completion, dichotomized at a ≥5% relative increase. Our primary study outcome was prevalence of post-TB metabolic syndrome (≥3 of the following: elevated blood pressure, elevated triglycerides, low high-density lipoprotein, elevated glycated hemoglobin [HbA1c], and abdominal obesity) at any study visit (including the end of treatment, 6 months post-TB treatment, and 12 months post-TB treatment). Multilevel models were used to estimate the effect of BMI change on post-TB metabolic syndrome.Results

Among 120 participants, the adjusted risk of having metabolic syndrome after TB treatment among those with a ≥5% relative increase in BMI was 2.1 times (95% CI, 1.1-4.0) the risk of those with a <5% relative increase in BMI during treatment. Additionally, the adjusted mean of post-TB HbA1c among those with a ≥5% relative increase in BMI was 0.4 (95% CI, 0.0-0.7) points higher compared with those with a <5% relative increase in BMI.Conclusions

Among individuals who were successfully treated, individuals who had a ≥5% increase in BMI during TB treatment had a significantly increased risk of metabolic syndrome and higher HbA1c levels up to 12 months after TB treatment.
