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).

From: Towards an understanding of barriers to condom use in rural Benin using the Health Belief Model: A cross sectional survey

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)
  1. 2 LL Chi-square: 32.2 P-value < 0.0001
  2. Score Chi-square: 32.2 P-value < 0.0001
  3. C-statistic = 0.81
  4. 1Crude OR: calculated from a univariate logistic regression
  5. 2 Adjusted OR: Calculated from a multivariate logistic regression including Perceived incomplete rotection using condoms and reporting any problem using condom.
  6. 3 NA: Not Applicable because these variables did not have an important effect on the use of condom.
