Table 4.
Crude* and adjusted** odds ratio (OR) estimates with their 95% Confidence Interval (95% CI) of the effect of perceived efficacy of condom, barriers to condom use, vulnerability and severity on the lack of condom use for 235 participants in a HIV/AIDS interview, Toffo county, Benin (June–July 2002).
| Variables | Crude OR1 (95% CI) | Adjusted OR2 (95% CI) |
| No perceived risk to HIV infection | 6.9 (0.9 – 52.5) | NA3 |
| AIDS not perceived as a deadly disease | 2.5 (0.3 – 19.7) | NA3 |
| Perceived incomplete protection using condoms | 11.5 (3.8 – 34.7) | 9.8 (3.2 – 30.0) |
| Reporting any problem using condom | 5.4 (2.1 – 13.7) | 3.6 (1.3 – 9.9) |
2 LL Chi-square: 32.2 P-value < 0.0001
Score Chi-square: 32.2 P-value < 0.0001
C-statistic = 0.81
1Crude OR: calculated from a univariate logistic regression
2 Adjusted OR: Calculated from a multivariate logistic regression including Perceived incomplete rotection using condoms and reporting any problem using condom.
3 NA: Not Applicable because these variables did not have an important effect on the use of condom.
