Table 2 shows the determinants of not being screened for HIV of the 1197 patients included in the analysis (98 were excluded for missing data: 88 on socio economic status and 10 on a single other variable). Receiving TB care in one of the health care facilities of the higher areas of the district (odds ratio (OR) = 3.38, confidence interval (CI) 95% 2.17–5.28, p < 0.0001 for the highest area and OR = 2.82, CI 95% 1.78–4.49, p < 0001, for the high area) as well as reporting illicit drug consumption (OR = 1.65, CI 95% 1.15–2.37, p = 0.0062) was associated to not being screened for HIV.Table 2Determinants of not being screened for HIV among 1197 patients with a first episode of smear positive pulmonary tuberculosis, San Juan de Lurigancho, 2010–2011CharacteristicsScreenedN(%)Not screenedN(%)Crude OR (95% CI) p Adjusted OR (95%CI) p Sex Female394 (78.5%)108 (21.5%)1 Male593 (74.8%)200 (25.2%)1.23 (0.94–1.63)0.136Age, in years 18–34721 (76.6%)220 (23.4%)0.94 (0.68–1.31)0.752 35–49210 (76.4%)65 (23.6%)1 > 5057 (72.1%)22 (27.9%)1.15 (0.63–2.09)Weight loss reported by the patient Yes798 (75.7%)256 (24.3%)1.07 (0.76–1.51)0.699 No186 (78.2%)52 (21.8%)1Location of health facility in district area Lowest area199 (85.8%)33 (14.2%)11 Middle area314 (87.0%)47 (13.0%)0.89 (0.54–1.47)0.90 (0.54–1.49)< 0.001 Highest area259 (65.6%)136 (34.4%)3.34 (2.15–5.21)3.38 (2.17–5.28) High area215 (70.0%)92 (30.0%2.8 (1.77–4.45)< 0.0012.82 (1.78–4.49)Education Primary or less400 (73.1%)147 (26.9%)1.23 (0.91–1.66)0.153 High School365 (78.0%)103 (22.0%)1 Higher221 (79.2%)58 (20.8%)0.88 (0.61–1.28)Socioeconomic status Poor240 (75.5%)78 (24.5%)1.09 (0.81–1.48)0.556 Not poor685 (77.0%)204 (23%)1Marital Status Married / cohabiting369 (75.8%)118 (2.2%)1.12 (0.84–1.49)0.523 Divorced72 (77.4%)21 (22.6%)0.88 (0.51–1.53) Single521 (76.8%)157 (23.2%)1 Widow25 (67.6%)12 (32.4%)1.57 (0.75–3.29)Illegal drug consumption Yes149 (68.3%)69 (31.7%)1.64 (1.16–2.32)0.0061.65 (1.15–2,37)0.006 No838 (77.8%)239 (22.2%)11Alcohol consumption (CAGE score) Yes52 (72.2%)20 (27.8%)1.28 (0.74–2.22)0.38 No534 (75.1%)177 (24.9%)1Ex prison inmate Yes49 (80.3%)12 (19.7%)0.68 (0.31–1.47)0.305 No936 (76.1%)296 (23.9%)1Diabetes Mellitus, as reported by the patient Yes41 (74.5%)14 (25.5%)1.12 (0.60–2.08)0.725 No944 (76.3%)294 (23.7%)1TB regimen Regimen for drug sensitive TB970 (76.1%)305 (23.9%)1 Regimens for drug resistant TB17 (85.0%)3 (15%)0.70 (0.20–2.44)0.556Employment Yes695 (75.8%)221 (24.2%)10.646 No190 (75.7%)61 (24.3%)0.99 (0.71–1.40) Student102 (79.7%)26 (20.3%)0.81 (0.50–1.28)Study Period 1261 (78.1%)73 (21.9%)1 2233 (76.9%)70 (23.1%)1.13 (0.76–1.67)0.431 3258 (75.9%)82 (24.1%)1.18 (0.80–1.73) 4235 (74.0%)83 (26.0%)1.37 (0.94–2.01)Place of birth Coastal region611 (76.3%)190 (23.7%)10.985 Jungle region138 (75.0%)46 (25.0%)0.97 (0.65–1.44) Andean region237 (76.7%)72 (23.3%)0.98 (0.71–1.35)
