Mediation effect of perceived behavioural control on intended condom use: applicability of the theory of planned behaviour to money boys in China

Prevalence and Factors of Concurrent Multiple Male Sex Partnership Among Men Who Have Sex With Men With Regular Sex Partners in Beijing, China

This study was to test whether the cognitive factors of the theory of planned behavior were associated with concurrent multiple male sex partnership (CMMSP) status (past three months) and intention to have CMMSP (next six months) among 251 men who have male regular sex partners in Beijing, China. The prevalence of having had CMMSP and intention to do so was 48.2% and 28.7%, respectively. Positive attitudes toward CMMSP, injunctive norm for not having CMMSP, and behavioral control for not having CMMSP were significantly associated with behavioral intention. Descriptive norm and perceived behavioral control were significant factors for CMMSP status.

Development and Psychometric Properties of a Condom Use and Its Cognitive Determinants Questionnaire (CUCDQ)

AIM

The aim of this study was to assess the psychometric properties of Condom Use and its Cognitive Determinants Questionnaire (CUCDQ) among married women in Tabriz, Iran.

MATERIALS AND METHODS

In this cross-sectional study, applying multistage cluster sampling 388 married women were recruited to participate in the study. A comprehensive literature review was conducted to develop CUCDQ. Face, content, and construct validity, as well as reliability, were investigated.

RESULTS

Principal component factor analysis with varimax rotation demonstrated a six factors structure as the best solution [Bartlett's Test of Sphericity (Approx. Chi-Square= 4193.07, df= 780, p<0.001); KMO= 0.815] which explained 43.13% of all the variance between the items. CUCDQ represented a proper validity, reliability, simplicity and functionality.

CONCLUSION

CUCDQ may be helpful for family health care providers and family planning decision makers in precise assessing the behavioural, psychological, and educational factors related to condom use. This scale may be useful in a various range of studies including family planning or STIs prevention studies in different communities. Future research is recommended to assess the different dimensions of the tool in different communities.

Biomarker validation of self-reported sex among middle-aged female sex workers in China

PURPOSE

The objective of this study was to examine information bias arising from self-reported sexual activity and its association with syphilitic infections among female sex workers (FSWs) aged 35 years and older in China.

METHODS

A questionnaire was administered to 1245 middle-aged FSWs. Respondents self-reported sexual intercourse in the past 48 hours. The prostate-specific antigen test was used to verify self-reported sexual activity. FSWs were considered discordant if they indicated no sexual intercourse in the past 48 hours on the questionnaire and had a positive prostate-specific antigen test. Logistic regression was used to assess the associations between discordance and syphilis.

RESULTS

Three hundred twenty FSWs self-reported no engagement in sexual intercourse in the past 48 hours. One-fourth of respondents (25%) were discordant. Twenty-two percent and 35.8% of discordant FSWs tested positive for active and prevalent syphilis, respectively. After adjusting for confounders, discordant FSWs had 3.8 times the odds of active syphilis (95% confidence interval: 1.52-9.30) and 2.6 times the odds of prevalent syphilis (95% confidence interval: 1.37-5.02), compared with concordant FSWs.

CONCLUSIONS

FSWs who had active or prevalent syphilis were more likely to be discordant. Data collected via self-reported questionnaire may not be a valid tool to assess sexual behavior.

Bias in Self-Reported Condom Use: Association Between Over-Reported Condom Use and Syphilis in a Three-Site Study in China

This study examined over-reporting bias in self-reported condom use and assessed its association with syphilis. A survey was conducted among 1245 female sex workers (FSWs) in three cities in China. Respondent's over-reported condom use was defined as reporting no unprotected sex for the past 24 h but testing positive for prostate specific antigen. The proportion of prevalent syphilis and active syphilis was 23 and 10 % respectively among FSWs. The proportion of over-reported condom use with sex clients only was 27-45 % among the three study sites. The proportion of over-reported condom use with all sex partners (clients, husbands, or boyfriends) was 26-46 %. FSWs who had active or prevalent syphilis were more likely to over report condom use. Self-reported condom use may not be a valid tool to measure the efficacy of HIV/STI intervention because the bias is associated with the outcome measure, i.e., syphilis.

Egocentric Network and Condom Use Among Mid-Age Female Sex Workers in China: A Multilevel Modeling Analysis

The epidemics of sexually transmitted infections (STIs) have spread among older adults in the world, including China. This study addresses the deficiency of studies about the multiple contextual influences on condom use among mid-age female sex workers (FSWs) over 35 years old. A combination of an egocentric network design and multilevel modeling was used to investigate factors of condom use over mid-age FSWs (egos) particular relationships with sexual partners (alters). Of the 1245 mid-age FSWs interviewed, 73% (907) reported having at least one sexual partner who would provide social support to egos. This generated a total of 1300 ego-alter sex ties in egos' support networks. Condoms were consistently used among one-third of sex ties. At the ego level, condoms were more likely to be used consistently if egos received a middle school education or above, had stronger perceived behavioral control for condom use, or consistently used condoms with other sex clients who were not in their support networks. At the alter level, condoms were not consistently used over spousal ties compared to other ties. Condoms were less likely to be used among alters whom ego trusted and provided emotional support. Cross-level factors (egos' attitudes toward condom use and emotional support from alters) documented a significant positive interaction on consistent condom use. Given the low frequency of condom use, future interventions should focus on mid-age FSWs and their partners within and beyond their support networks.
