    Low Nutrient Intake Among Adult Women and Patients With Severe Tuberculosis Disease in Uganda: A Cross-Sectional Study
    (BMC Public Health, 2012-12) Mupere, Ezekiel; Parraga, Isabel M; Tisch, Daniel J; Mayanja, Harriet K; Whalen, Christopher C
    Background: Information regarding dietary nutrient intake during tuberculosis disease is lacking. We established the relationship between disease severity or wasting during pulmonary tuberculosis and nutrient intake. Methods: In a cross-sectional study of 131 adults with or without pulmonary tuberculosis were screened for human immune-deficiency virus (HIV), wasting, disease severity using 13 item validated clinical TBscore, and 24-hour dietary intake recall. Results: Of the 131 participants, 61 were males and 70 females. Overall men and women had similar age. In average 24-hour nutrient intake, the following nutrients: energy, protein, total fat, carbohydrate, calcium, vitamin A, and folate were low among patients with severe tuberculosis disease. Patients with moderate-to-severe clinical TBscore had lower average energy intake than patients with mild TBscores (6.11 vs. 9.27 MJ, respectively) (p<0.05). The average 24-hour nutrient intakes between wasted and non-wasted tuberculosis patients were comparable. Nutrient intake among men was higher when compared to women regardless of wasting and severity of tuberculosis. Among those with wasting, men had higher average energy intake than women (8.87 vs. 5.81 MJ, respectively) (p<0.05). Among patients with mild disease, men had higher average energy intake than women with mild disease (12.83 vs. 7.49 kcal, respectively) (p<0.001). Conclusions: Findings suggest that severity of pulmonary tuberculosis and female gender had reduced nutrient intake. Early tuberculosis diagnosis and nutritional support may be important in management of tuberculosis patients.

    Wasting Among Uganda Men With Pulmonary Tuberculosis Is Associated With Linear Regain in Lean Tissue Mass During and After Treatment in Contrast to Women With Wasting Who Regain Fat Tissue Mass: Prospective Cohort Study
    (BMC Infectious Diseases, 2014-01) Mupere, Ezekiel; Malone, LaShaunda; Zalwango, Sarah; Okwera, Alphonse; Nsereko, Mary; Tisch, Daniel J; Parraga, Isabel M; Stein, Catherine M; Mugerwa, Roy; Boom, W Henry; Mayanja, Harriet K; Whalen, Christopher C
    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.
