Introduction: a significant proportion of road construction workers are migrants and prone to HIV infection. This study investigated the psychosocial predictors of consistent condom use among migrant road construction workers in the South-west region of Cameroon using the Health Belief Model (HBM) as the theoretical framework.

Methods: a cross-sectional survey of a stratified sample of 254 road construction workers was conducted at construction sites along the Kumba-Mamfe road in the South-west region of Cameroon in December 2015. Data were collected using a pretested structured questionnaire and binomial logistic regression was performed to test the strength of association between the independent and the dependent variables using SPSS version 20 at the level 0.05.

Results: only 67 (43.5%) reported consistent condom use. Perception of risk of contracting HIV was also low, 109 (42.9%). None of the constructs of the HBM was significantly associated with consistent condom use. However, perception that road construction workers are prone to HIV (perceived susceptibility) was associated with an increased likelihood of using condom consistently, OR = 2.1 (95% CI 0.72-6.12, p = 0.17); perception that consistent condom use could prevent HIV transmission (perceived benefit) was associated with an increased likelihood of using it consistently, OR = 1.9 (95% CI 0.74-4.80, p = 0.18); perception by workers that they can refuse sex with their partners if they refuse to use condoms (perceived self-efficacy) was associated with an increased likelihood of using condoms consistently, OR = 1.5 (95% CI 0.62-3.53, p = 0.38). However, the perception that condom reduces sexual pleasure (perceived barriers) was associated with a reduced likelihood of using it consistently, OR = 0.84 (95% CI 0.35-2.01, p = 0.698).

Conclusion: there were no significant associations between the psycho-social constructs of the HBM and consistent condom use. Therefore, interventions to increase the perception of risk of contracting HIV, which is assumed to be the immediate antecedent of consistent condom use is highly recommended.
