Identifying risk: a comparison of risk between heterosexual-identifying bisexual men and other bisexual men in Vientiane, Laos.

Men who have sex with men are a priority population for HIV control in Laos, but encompass men diverse in sexual orientation, gender identification, and behavior. Behaviorally bisexual men and their sexual partners were recruited in Vientiane, Laos, in 2010 using modified snowball sampling. Heterosexual-identifying bisexual men identified as exclusively/predominantly heterosexual and other bisexual men identified as bisexual or predominantly/exclusively homosexual. Sixty (68%) heterosexual-identifying and 38 (32%) other bisexual men were recruited; the median number of sex partners in the past year was eight and seven, respectively. Consistent condom use was low with regular (7%) and casual (35%) partners and did not differ by identity. More heterosexual-identifying (53%) than other bisexual (29%) men reported weekly alcohol consumption. Twelve (20%) heterosexual-identifying and 15 (54%) other bisexual men correctly answered all HIV-knowledge questions. High-risk behaviors for STI and HIV transmission were common. Targeted HIV prevention initiatives are needed, particularly to reach heterosexual-identifying bisexual men.

Factors associated with antenatal care utilization among rural women in Lao People's Democratic Republic.

This study aims at exploring factors related to the antenatal care (ANC) utilization in rural areas of Lao PDR. A quantitative, cross-sectional interview study was conducted in the Khammouane and Champasack provinces. The study population comprised all currently pregnant women 15-45 years of age with a gestational period beyond 32 weeks plus all women who had given birth during the last 12 months. With the informed consent of all eligible women, 460 respondents were included in the study and interviewed using a structured questionnaire. Multiple logistic regression analysis was applied to determine factors significantly related to ANC use. Fifty-one percent of the respondents had at least one ANC visit. Among the users, 63% had visited ANC three times or more but only 28% attended during the first trimester. After adjusting for other factors, using a 95% Confidence Interval (CI), statistically significant associations were found between ANC use and the following factors: women whose husbands were salaried employees (OR=2.66, CI=1.45-4.88); women younger than 18 years old at first pregnancy (OR 0.56, CI=0.28-0.97); women perceiving ANC as somewhat useful (OR=2.88, CI=1.26-6.61) or very useful (OR=7.45, CI=3.59-15.46). Awareness of the usefulness of ANC was related to more frequent use and could be one focus of community intervention to increase utilization.

Reproductive tract infections including sexually transmitted infections: a population-based study of women of reproductive age in a rural district of Vietnam.

OBJECTIVES: To investigate the prevalences of reproductive tract infections (RTI)/sexually transmitted infections (STI) among married women in a rural district of Vietnam, and analyse the influence of socioeconomic, sociodemographic, and other determinants possibly related to RTI/STI. METHODS: A community-based cross-sectional study. Married women aged 18-49 years (n = 1012) were interviewed and underwent a gynaecological examination. Specimens were collected for laboratory diagnosis of chlamydia, gonorrhoea, trichomonas, bacterial vaginosis (BV), candidiasis, hepatitis B, HIV, and syphilis. RESULTS: In total, 37% of the women were clinically diagnosed with an RTI/STI. Aetiologically confirmed RTI/STI was identified in 39% of the women (including 6% with STI). Endogenous infections were most prevalent (candidiasis 26%, BV 11%) followed by hepatitis B 8.3%, Chlamydia trachomatis 4.3%, Trichomonas vaginalis 1%, Neisseria gonorrhoeae 0.7%, genital warts 0.2%, and HIV and syphilis 0%. Fifty per cent of the STI cases were asymptomatic. Younger age and intrauterine devices were significantly associated with an increased risk of BV. Determinants of candidiasis were vaginal douching, high education level and low economic status, whereas a determinant of chlamydia was high economic status. Outmigration of the husband was associated with an increased risk of hepatitis B surface antigen seroposivity among women. CONCLUSIONS: RTI/STI were prevalent among married women in a rural population of Vietnam. Syndromic algorithms should be consistently supplemented by risk assessment in order to reduce under and overtreatment. Microscopic diagnosis could be applied in primary care settings to achieve more accurate diagnoses. The promotion of health education aimed at reducing RTI/STI prevalences is an important tool in STI/HIV control programmes. Vaccination to prevent hepatitis B for migrants should be considered.

Antimicrobial self medication for reproductive tract infections in two provinces in Lao People's Democratic Republic.

OBJECTIVES: To describe antimicrobial self medication for reproductive tract infections (RTI) including sexually transmitted infections (STI), and to explore the understanding and use of health information among the adult population self medicating with antimicrobials for RTI/STI in two provinces of Laos. This could contribute to quality improvement of RTI/STI management. METHODS: Cross sectional community based study. Structured interviews (household survey) were conducted among 500 subjects aged 18 or more, who had used antimicrobials as self medication for RTI/STI during the past year. They were recruited among 3056 family members in Vientiane capital and Champasak province, divided equally between the two study sites, and between urban and rural areas. RESULTS: Among the 500 respondents reporting self medication for RTI/STI, 91% had bought the antimicrobials from local private pharmacies without a physician's prescription. 58% of those were advised to buy the drugs from drug sellers. Ampicillin (not recommended as syndromic treatment for RTI/STI) was used in 83% of all cases, in 28% combined with tetracycline. 79% of respondents used antimicrobials for a non-recommended duration of time. Most respondents had access to health messages for RTI/STI, largely from radio/television and drug sellers. However, only 17% of all respondents reported that they had ever used a condom. CONCLUSIONS: More than three quarters of respondents, self medicating for RTI/STI with antimicrobials, used inappropriate drugs bought from private pharmacies. There is a need to improve RTI/STI management, including health promotion, through interventions at community level, and to health providers, including private drug sellers.
