Background: Previous studies have shown gender differences in tuberculosis (TB) incidence; however, gender disparity has not been well documented across granular categorizations of anatomic sites affected by TB and in the presence of human immunodeficiency virus (HIV) coinfection, largely due to small sample size for less common TB clinical presentations and lack of detailed clinical data. Methods: = 41, 266) diagnosed in Harare, Zimbabwe. This cross-sectional study estimated male-to-female ratio (M/F ratio) for (1) age-specific TB incidence, (2) age-specific HIV prevalence among incident TB cases, and (3) 9 types of TB defined by affected anatomic site. Results: Males were at a 53% higher risk of TB compared to females (risk ratio RR = 1.53; 95% confidence interval CI, 1.12-2.09). Based on adjusted odds ratios (aORs) from multinomial logistic regression model, the odds of abdominal TB (aOR = 0.51; 95% CI, .39-.68), TB bones/joints/spine (aOR = 0.63; 95% CI, .45-.90), and "other" extrapulmonary TB sites (aOR = 0.69; 95% CI = .59-.81) versus pulmonary TB were lower among males compared to females. The risk of TB-HIV coinfection among males was 17% (RR = .83; 95% CI, .74-.93) and 8% (RR = 0.92; 95% CI, .88-.95) lower in the 15- to 24-year and 25- to 44-year age groups, respectively. Conclusions: This study revealed a nuanced role of gender across finer categorizations of TB, indicating the need for future research to delineate underlying mechanisms driving gender disparities in TB. The finding that women had a greater likelihood of severe forms of TB and TB-HIV coinfection compared to men has important implications for women's health in TB-HIV high-burden settings.
