Table 2 Associations of age, marital status, hormonal contraceptive use and recent sex with schistosome infection as assessed by multivariable logistic regression

From: Schistosoma mansoni infection and socio-behavioural predictors of HIV risk: a cross-sectional study in women from Uganda

Participant characteristic Entire cohort (n = 58) Schistosoma spp. ag -positive (N = 33) Schistosoma spp. ag -negative (N = 25) OR for association with schistosomiasis (95% CI) P value (α = 0.05)
Median age (IQR) 27.5 (23.8–32.0) 25.0 (22.5–29.5) 30.0 (25.0–34.0) 0.934 (0.838–1.041) 0.216
Married, % 60.7 (34/56) 50.0 (16/32) 79.2 (19/24) 0.590 (0.138–2.527) 0.477
Sexual behaviour
 Hormonal contraceptive use, % 30.4 (17/56) 12.5 (4/32) 54.2 (13/24) 0.151 (0.037–0.611) 0.008
  DMPA*, % 19.6 (11/56) 9.4 (3/32) 33.3 (8/24)
  NetEn*, % 8.9 (5/56) 3.1 (1/32) 16.7 (4/24)
  Oral pill, % 1.8 (1/56) 0 (0/32) 4.2 (1/24)
Sex in last 3 days
 PSA+, % 41.8 (23/55) 31.3 (10/32) 56.5 (13/23) 0.480 (0.130–1.773) 0.271
  1. ag antigen, OR odds ratio, DMPA depot-medroxyprogesterone acetate, NET-EN norethisterone enanthate, PSA prostate-specific antigen. Data were assessed using multivariable binomial logistic regression with factors that were found to have significant associations in univariate analysis and the Schistosoma spp. ag-free (CCA-negative) group as the reference category. When OR is above 1, there is a positive association of given factor with schistosomiasis; OR value above 1 represents inverse relationship of given factor with schistosomiasis. OR for age is a per year OR
