Impact of Undernutrition on Tuberculosis Treatment Outcomes in India: A Multicenter Prospective Cohort Analysis.
BACKGROUND
Undernutrition is the leading risk factor for tuberculosis (TB) globally. Its impact on treatment outcomes is poorly defined.
METHODS
We conducted a prospective cohort analysis of adults with drug-sensitive pulmonary TB at five sites in the Regional Prospective Observational Research on Tuberculosis (RePORT) India consortium (2015-2019). Using multivariable Poisson regression, we assessed independent associations between unfavorable outcomes and nutritional status based on body mass index (BMI) nutritional status at treatment initiation, BMI prior to TB disease, stunting, and stagnant or declining BMI after two months of TB treatment. Unfavorable outcome was defined as a composite of treatment failure, death, or relapse within 6 months of treatment completion.
FINDINGS
Severe undernutrition (BMI < 16 kg/m2) at treatment initiation and severe undernutrition before the onset of TB disease were both associated with unfavorable outcomes (adjusted incidence rate ratio [aIRR]: 2.05; 95% confidence interval [CI]: 1.42-2.91 and 2.20; 95% CI: 1.16-3.94, respectively). Additionally, lack of BMI increase after treatment initiation was associated with increased unfavorable outcomes (aIRR: 1.81; 95% CI: 1.27-2.61). Severe stunting (height-for-age z-score < -3) was associated with unfavorable outcomes (aIRR: 1.52; 95% CI: 1.00-2.24). Severe undernutrition at treatment initiation and lack of BMI increase during treatment were associated with a four and five-fold higher rate of death, respectively.
INTERPRETATIONS
Premorbid undernutrition, undernutrition at treatment initiation, lack of BMI increase after intensive therapy, and severe stunting are associated with unfavorable TB treatment outcomes. These data highlight the need for addressing this widely prevalent TB comorbidity. Nutritional assessment should be integrated into standard TB care.
