Applying the pre-intentional phase of the Health Action Process Approach (HAPA) Model to investigate factors associated with intention on consistent condom use with various types of female sex partners among males who inject drugs in China.

Both drug injection and sexual transmission are the primary drivers of the HIV epidemic in China. This study investigated the prevalence and associated factors of intention of consistent condom use during sexual intercourse with female regular partners (RP), non-regular partners (NRP) and sex workers (FSW) among male people who inject drugs (PWID)in China. A total of 529 male non-institutionalized PWID aged 18-45 years with negative/unknown HIV status were recruited by multiple methods in Dazhou and Hengyang, China.

Relationship between sexual compulsivity and sexual risk behaviors among Chinese sexually active males.

Compulsivity is defined as "an insistent, repetitive, intrusive, and unwanted urge to perform specific acts often in ritualized or routinized fashions." Sexual compulsivity has been shown to be associated with some high risk sexual behaviors related to HIV and sexually transmitted infection (STI). In some Western countries, the 10-item Sexual Compulsivity Scale (SCS) has been developed to assess people's sexual compulsivity but no Chinese version has been validated.

Coverage and parental perceptions of influenza vaccination among parents of children aged 6 to 23 months in Hong Kong.

Background: The impact of influenza on young children can be severe and even fatal. Influenza vaccination (IV) has been shown to be effective in reducing complications of influenza among children. This study investigated the prevalence and factors of IV among children aged 6-23 months in Hong Kong.

A pilot clustered randomized control trial evaluating the efficacy of a network-based HIV peer-education intervention targeting men who have sex with men in Hong Kong, China.

HIV is a serious health threat among men who have sex with men (MSM). A 2-month pilot network-based peer intervention was conducted among Chinese MSM in Hong Kong. Eight MSM peer educators were randomized into the Intervention or the Control Groups and recruited 36 and 33 peers to join the program, respectively.

Awareness and acceptability of female condoms among monogamous Hong Kong Chinese female sexually transmitted infection patients.

Female condom is an effective means of HIV prevention. Monogamous female sexually transmitted infection (STI) patients are exposed indirectly to high risk of contracting HIV/STI via their sole male sex partners. There are few interventions to protect such women whilst female condom use is a potential means of self-protection.

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).

Prevalence and associated factors of condom use during commercial sex by female sex workers who were or were not injecting drug users in China.

Objectives: We compared the prevalence of inconsistent condom use during commercial sex between female sex workers (FSWs) who did or did not inject drugs (FSW-IDUs and FSW-NIDUs) and investigated factors associated with this inconsistent use within these two groups.

Methods: Some 158 FSW-NIDUs recruited from sex work venues and 218 FSW-IDUs recruited via the snowball sampling method were interviewed anonymously.

Results: Only 16.

A simple new method to triangulate self-reported risk behavior data--the bean method.

Background: Human immunodeficiency virus (HIV)/sexually transmitted disease (STD)-related interventions rely on self-reported risk behavioral data, which are biased toward social desirability. It is warranted to develop methods for data triangulation.

Methods: Some questions on HIV/STD-related behaviors that were asked in 5 face-to-face (FTF) surveys were repeated at the end of the surveys, using the newly developed bean method (BM), which requested participants to transfer a bean of a particular color from a large jar to a smaller one, depending on whether the answer was affirmative (yellow, white, green, or red) or not (black); both jars contained 500 mixed-up colored beans.

Setting up a surveillance system for sexually transmitted diseases in the general population with prospective data collection from private-practice and public-practice doctors in Hong Kong.

Background: Existing surveillance systems for sexually transmitted diseases (STD) and reproductive tract infections (RTI) are important but often ineffective, as they tend to omit cases diagnosed by private-practice doctors

Methods: During a 15-day study period, 277 private-practice doctors and all public-practice doctors of all the eight local Social Hygiene Clinics (SHC) in Hong Kong filled out daily a standard log-form, recording the number of patients diagnosed with particular types of STD/RTI. Projections for all local private-practice and public-practice doctors were made by the stratification method.

Results: Data showed that 0.

Incidence of genital warts among the Hong Kong general adult population.

Background: The objective of this study is to estimate the incidence of genital warts in Hong Kong and explore a way to establish a surveillance system for genital warts among the Hong Kong general population.

Methods: A total of 170 private doctors and all doctors working in the 5 local Social Hygiene Clinics (SHC) participated in this study. During the 14-day data collection period (January 5 through 18, 2009), the participating doctors filled out a log-form on a daily basis to record the number of patients with genital warts.

Sexual mixing and condom use with different types of sex partners among non-institutionalized sexually active female injecting drug users in Sichuan, China.

Behavioral surveillance data of 1422 sexually active female injecting drug users (IDU) in Sichuan China were analyzed. The prevalence of syringe-sharing was 43.5%.

Prevalence of influenza vaccination and associated factors among pregnant women in Hong Kong.

Avoidance behaviors and negative psychological responses in the general population in the initial stage of the H1N1 pandemic in Hong Kong.

Background: During the SARS pandemic in Hong Kong, panic and worry were prevalent in the community and the general public avoided staying in public areas. Such avoidance behaviors could greatly impact daily routines of the community and the local economy. This study examined the prevalence of the avoidance behaviors (i.

Comparison of risk behaviors and socio-cultural profile of men who have sex with men survey respondents recruited via venues and the internet.

Background: Increasingly more men who have sex with men (MSM) are using the internet to seek sex partners, and many HIV-related studies targeting MSM collect data from gay venues in order to inform the design of prevention programs. However, internet-based MSM may have different HIV risk behaviors and associated factors from those attending venues. This study examined differences in risk behaviors and socio-cultural profiles between MSM recruited from venues (e.

A randomized controlled trial to evaluate the relative efficacy of adding voluntary counseling and testing (VCT) to information dissemination in reducing HIV-related risk behaviors among Hong Kong male cross-border truck drivers.

Mobile populations are vulnerable to contracting HIV. The present study aims to evaluate the relative efficacy of the voluntary counseling and testing plus information dissemination (VCT-ID) approach versus the information dissemination (ID) approach for promoting HIV preventive behaviors in a mobile population, cross-border truck drivers. A total of 301 adult male cross-border truck drivers who self-reported having had sex with female sex workers (FSW) or non-regular sex partners (NRPs) in mainland China in the last 12 months were recruited and randomized into the VCT-ID intervention group (Group I) or ID control group (Group C).

Widespread public misconception in the early phase of the H1N1 influenza epidemic.

Objectives: To investigate the community responses and preparedness for a possible epidemic of H1N1 influenza in Hong Kong shortly after an imported case was confirmed.

Methods: A random sample of 550 Chinese adults in the Hong Kong general population was interviewed during May 7-9, 2009.

Results: The public did not perceive a high likelihood of having a local H1N1 outbreak, nor did they regard H1N1 as a threatening disease.
