Abstract
Background: Nutritional changes during and after tuberculosis treatment have not been well described. We
therefore determined the effect of wasting on rate of mean change in lean tissue and fat mass as measured by
bioelectrical impedance analysis (BIA), and mean change in body mass index (BMI) during and after tuberculosis
treatment.
Methods: In a prospective cohort study of 717 adult patients, BMI and height-normalized indices of lean tissue
(LMI) and fat mass (FMI) as measured by BIA were assessed at baseline, 3, 12, and 24 months.
Results: Men with wasting at baseline regained LMI at a greater rate than FMI (4.55 kg/m2 (95% confidence interval (CI): 1.26, 7.83 versus 3.16 (95% CI: 0.80, 5.52)) per month, respectively during initial tuberculosis therapy. In contrast, women with wasting regained FMI at greater rate than LMI (3.55 kg/m2 (95% CI: 0.40, 6.70) versus 2.07 (95% CI: -0.74,4.88)), respectively. Men with wasting regained BMI at a rate of 6.45 kg/m2 (95% CI: 3.02, 9.87) in the first three months whereas women, had a rate of 3.30 kg/m2 (95% CI: -0.11, 6.72). There were minimal changes in body composition after month 3 and during months 12 to 24.
Conclusion: Wasted tuberculosis patients regain weight with treatment but the type of gain differs by gender
and patients may remain underweight after the initial phase of treatment.
