Prevalence and factors associated with condom use among Chinese monogamous female patients with sexually transmitted infection in Hong Kong.

Introduction: Monogamous female sexually transmitted infection (STI) patients are at high risk of recurrent STI, but there is no study investigating their risk behaviors.

Aim: We investigated the prevalence of male condom use and associated factors among monogamous STI female patients.

Main Outcome Measures: Independent variables included socio-demographic characteristics, STI history, nature of relationship, and cognitions (Health Belief Model). Dependent variables included the use of male condoms in the past two months and intention to use male condoms consistently in the future 6 months.

Methods: A cross-sectional survey using a structured questionnaire was conducted among STI female patients with only one male sex partner in the last 12 months and attended a major government STI clinic in Hong Kong.

Results: Among the 538 participants, 25.1% used condoms consistently (every time) during sex in the past 2 months, while 35.2% intended to do so in the next 6 months. A multiple stepwise logistic regression model identified three statistically significant factors associated with lower likelihoods of consistent condom use in the past 2 months: type of sole sex partner (cohabitant vs. husband: OR = 0.29, 95% CI = 0.12 to 0.70; regular boyfriend vs. husband: OR = 0.52, 95% CI = 0.30 to 0.91), being financially dependent (OR = 0.45, 95% CI = 0.27 to 0.75), and partner's dislike of condom use (OR = 0.23, 95% CI = 0.15 to 0.39). In a similar model, the same three factors were found to be significantly associated with the intention to use condoms consistently in the next 6 months. The low prevalence of intention to use condoms consistently in the future suggested that our study population might be victimized again. The impact of financially dependent relationships and men's dislike of using condoms on condom use may operate through imbalanced gender power.

Conclusions: Interventions are greatly warranted and should increase risk awareness and empower this vulnerable population.
