Aim To evaluate habitual dietary intake of macronutrients and links with body composition in TB patients in Tbilisi, Georgia. Method Dietary intake was obtained from patients at TB diagnosis using a tool that captures specific foods common in Georgian culture. Foods consumed during the previous 3 days were determined by one‐on‐one interviews. Food intake data was entered into the NDS‐R software program and mean daily macronutrient intake determined. Body mass index (BMI; kg/m 2 ) and body composition by bioelectrical impedance analysis were determined. Descriptive statistics, unpaired t‐tests and linear regression methods were used. Results In the 199 subjects (mean age 34 y; 64% male), BMI averaged 20.9±3.5 (SD) kg/m 2 ; fat mass was 21.7±10.7% and fat‐free mass was 78.3±10.7% of body weight. Total energy intake averaged 54±21 kcal/kg/day (35% fat, 55% CHO and 12% protein). Protein intake averaged 1.6±0.7 g/kg/day. Underweight subjects (BMI ≤ 18.5 kg/m 2 ; n=43) consumed more total energy (64±21 vs. 51±21 kcal/kg/d; p=0.0007), protein (1.9±0.7 vs. 1.5±0.7; p=0.0008) and fat (2.4±1.0 vs. 2.0±1.0 g/kg/d; p=0.0254) vs. those with BMI >; 18.5 kg/m 2 (n=149). BMI negatively correlated with calorie, fat and protein intake, respectively (p=0.001). Conclusions TB patients in Tbilisi, Georgia exhibited a low‐normal BMI, were generally lean and 22% were underweight. Overall, subjects consumed a high‐kcal, high‐protein diet from mixed nutrient food sources. Underweight patients consumed significantly higher amounts of macronutrients than non‐underweight patients.
