Contraceptive use in HIV-positive women

The objective was to describe contraceptive use in women with HIV infection in France over the past decade. The study included 575 sexually active women of reproductive age, who knew the serologic status of their steady partners. It is part of a prospective observational study initiated in 1993 that was designed to investigate the gynecologic status of HIV-infected women. Women answered a standardized questionnaire about contraceptive use and sexual activity at each semiannual visit. Multivariate models were used to investigate parameters associated with the use of contraceptive methods. Contraceptive use was reported in 91% of the visits of women with an HIV-seronegative partner and 69% of women with an HIV-seropositive partner (P=0.0001). Consistent condom use was higher in serodiscordant couples than in seroconcordant couples (odds ratio [OR]=6.1, 95% CI=0.1-0.2, P<0.001). The use of oral contraception and intrauterine devices was higher in seroconcordant than in serodiscordant couples (OR=2.1, 95% CI=.5-2.9, P<0.001). Among women with an HIV-seronegative partner, the use of oral contraception and intrauterine devices decreased after the introduction of highly active antiretroviral therapy in 1998 (P=0.02) and was higher in couples with inconsistent condom use (OR=2.0, 95% CI=1.3-3.3). These data emphasize that contraception counseling should include a discussion on reproductive issues as well as transmission of HIV and other sexually transmitted infections, taking into account the partner's serostatus.     

Effect of maternal HIV and malaria infection on pregnancy and perinatal outcome in Zimbabwe

OBJECTIVE: To investigate the effect of isolated or concomitant infection with malaria and HIV on pregnancy and neonatal outcome. METHODS: Data were collected on pregnant women admitted during the rainy seasons in the obstetric division of a district referral hospital in northern Zimbabwe in 2000 and 2001. The effects of malaria and HIV infection were determined by multivariate analysis. RESULTS: The prevalence of HIV seropositivity and symptomatic malaria in 986 pregnant women was 8.3% and 14.7%, respectively. HIV-infected women were more likely to develop malaria attacks during pregnancy than seronegative women (odds ratio [OR] = 3.96, 95% confidence interval (CI): 2.42-6.46). Malaria and HIV infections were associated with increased risk of stillbirth (OR = 4.74, 95% CI: 1.34-16.78) and preterm delivery (OR = 4.10, 95% CI: 2.17-7.75), respectively. They were independently associated with increased risk of low birth weight (malaria: OR = 10.09, 95% CI: 6.50-15.65; HIV: OR = 3.16, 95% CI: 1.80-5.54) and very low birth weight (malaria: OR = 5.04, 95% CI: 1.00-25.43; HIV: OR = 10.74, 95% CI: 2.12-54.41), low Apgar score (malaria: OR = 4.45, 95% CI: 1.42-13.94; HIV: OR = 5.94, 95% CI: 1.66-21.30), and fetal growth restriction (malaria: OR = 3.98, 95% CI: 2.51-6.30; HIV: OR = 4.07, 95% CI: 2.40-6.92). Dual infection with malaria and HIV was associated with increased risk of maternal, perinatal, and early infant death. CONCLUSIONS: Women with single HIV or malaria infection have a significantly increased risk of adverse outcomes of pregnancy and childbirth. Dual infection has additional detrimental effects on maternal and infant survival in an area where HIV and malaria coexist.     

Mode of delivery and postpartum morbidity among HIV-infected women: the women and infants transmission study

Cesarean delivery before onset of labor and rupture of membranes (i.e., scheduled cesarean delivery) is associated with a lower risk of vertical transmission of HIV. The following a priori hypotheses were tested: among HIV-infected women, scheduled cesarean delivery is associated with a higher risk of postpartum morbidity, longer hospitalization, and a higher risk of rehospitalization than spontaneous vaginal delivery. Postpartum morbidity occurred following 178 of 1,186 (15%) of deliveries during 1990 to 1998 in The Women and Infants Transmission Study. The most commonly reported postpartum morbidity events were: fever without infection, hemorrhage or severe anemia, endometritis, urinary tract infection, and cesarean wound complications. Several time trends were observed: the median duration of ruptured membranes decreased (p < .001), intrapartum antibiotic use increased (p < .001), the median antepartum plasma HIV RNA concentration decreased (p < .001), and the incidence of any postpartum morbidity decreased (p = .02). With spontaneous vaginal delivery as the reference category, both scheduled (odds ratio [OR] = 4.69; 95% confidence interval [95% CI], 2.03-10.84), and nonscheduled (OR, 2.50; 95% CI, 1.24-5.04) cesarean deliveries were associated with fever without infection; with urinary tract infection (OR, 3.79; 95% CI 1.04-13.85; OR, 3.86; 95% CI, 1.55-9.60, respectively), and with any postpartum morbidity (OR, 3.19; 95% CI 1.69-6.00; OR, 4.10; 95% CI, 2.71-6.19, respectively). Nonscheduled cesarean deliveries were more likely to be complicated by endometritis (OR, 6.98; 95% CI, 3.53-13.78). Adjusted ORs relating mode of delivery and each of the outcomes (fever without infection, urinary tract infection, endometritis, and any postpartum morbidity) were similar to unadjusted ORs. Results of this analysis indicate scheduled cesarean delivery is associated with an increased risk of any postpartum morbidity and, specifically, postpartum fever without infection. The potential for postpartum morbidity with scheduled cesarean delivery should be considered in light of possible adverse events associated with other interventions to decrease the risk of vertical transmission of HIV. Counseling of HIV-infected pregnant women regarding scheduled cesarean delivery as a possible intervention to decrease maternal-infant transmission of HIV should include discussion of these results, as well as new data as they become available, regarding the incidence and severity of postpartum morbidity events among HIV-infected women according to mode of delivery.     

Use of a public sexually transmitted disease clinic by known HIV-positive adults: decreased self-reported risk behavior and increased disease incidence

High-risk sexual behavior by HIV-positive individuals is an important factor contributing to the spread of the HIV epidemic. We conducted a retrospective chart review to compare self-reported sexually transmitted disease (STD) risk behavior and clinic diagnoses of known HIV-positive clients attending Miami-Dade County STD clinics with those of uninfected controls. One hundred ninety-one HIV-positive clients and 191 HIV-negative controls, 130 (68.1%) men and 61 (31.9%) women, were included in the analysis. HIV-positive clients were more likely than controls to report no sexual activity in the last 2 months (odds ratio [OR] = 2.6, 95% confidence interval [CI]: 1.5-4.5) or, if active, to report condom use at last sexual intercourse (OR = 3.1, CI: 1.9-5.3). However, HIV-positive clients were more likely to be diagnosed with infectious syphilis (OR = 13.0, CI: 1.6-99.4) and/or gonorrhea (OR = 2.1, CI: 1.1-4.2) than controls. This may be a result of overreporting of condom use or sexual activity in high-risk sexual networks with inefficient use of condoms. Ongoing sexual risk behavior and access to HIV primary care are important issues in this population.     

Personal risk perception, HIV knowledge and risk avoidance behavior, and their relationships to actual HIV serostatus in an urban African obstetric population

One quarter of pregnant women in Zambia are infected with HIV. Understanding how knowledge of HIV relates to personal risk perception and avoidance of risky behaviors is critical to devising effective HIV prevention strategies. In conjunction with a large clinical trial in Lusaka, Zambia, we surveyed postpartum women who had been tested for HIV but did not know their status before undergoing the questionnaire. Of 858 women for whom complete data were available, 248 (29%) were HIV infected. Women 22 years of age or older (adjusted odds ratio [AOR], 1.7; 95% confidence interval [CI], 1.1-2.5), women reporting > or =2 sexual partners in their lifetime (AOR, 1.8; 95% CI, 1.3-2.5), and women reporting a history of a sexually transmitted infection (AOR, 2.7; 95% CI, 1.7-4.3) were more likely to be HIV infected. Having had > or =2 lifetime sexual partners was a marker for perception of high personnel risk for HIV infection (AOR, 1.5; 95% CI, 1.1-2.1). However, there was no relationship between perceived risk of HIV infection and actual HIV status. In fact, 127 (52%) of 245 women who stated that they were at no or low risk for HIV infection were HIV infected. Living in an area of high HIV seroprevalence like Zambia seems to be the greatest risk factor for infection in unselected pregnant women. Before significant inroads can be made in decreasing the incidence of HIV infection among pregnant women, population-based strategies that involve men must be implemented.     

Independent effects of reported sexually transmitted infections and sexual behavior on HIV-1 prevalence among adult women, men, and teenagers in rural Uganda

OBJECTIVE: To assess whether sexually transmitted infections (STIs) and sexual behavior are independently associated with HIV-1 among adult women, men, and teenagers in rural Uganda. DESIGN: Cross-sectional survey. METHODS: All adults (13 years and older) residing in 18 communities were invited to participate. HIV status was determined from serum samples and data collected during confidential interview. Independent effects of risk factors for HIV were estimated using adjusted odds ratios (ORs) with 95% confidence intervals (CIs) from logistic regression. RESULTS: Women reporting genital ulcers in the last 12 months were over twice as likely to be HIV positive after adjustment for sociodemographic factors and number of lifetime sexual partners (OR, 2.5; 95% CI, 1.9-3.4). Equivalent associations were stronger for men (OR, 3.2; 95% CI, 2.2-4.7) but weaker for teenagers (OR, 2.0, 95% CI, 0.5-8.7). Number of lifetime sexual partners was associated ( p <.05) with HIV status for women, men, and teenagers independently of reported genital ulcers. Teenagers reporting casual partners were over four times ( p <.001), and men reporting condom use almost twice ( p <.001), as likely to be HIV positive. Neither history of genital discharge nor other measures of sexual behavior were independently related to HIV status. CONCLUSION: Reported STIs and sexual behavior are independently associated with HIV in rural Uganda. Community-based interventions to reduce HIV should target both and should include teenagers.     

Factors associated with self-efficacy for condom use and sexual negotiation among South african youth

OBJECTIVES: To use logistic regression modeling to identify factors associated with high self-efficacy for sexual negotiation and condom use in a sample of South African youth. METHODS: The Reproductive Health and HIV Research Unit (RHRU) National Youth Survey examined a nationally representative sample of 7409 sexually active South African youth aged 15 to 24 years. We used logistic regression modeling in this sample to identify factors associated with the main outcome of high self-efficacy. RESULTS: Among female respondents (n = 3890), factors associated with high self-efficacy in the adjusted model were knowing how to avoid HIV (odds ratio [OR] = 2.30, 95% confidence interval [CI]: 1.05 to 5.00), having spoken with someone other than a parent or guardian about HIV/AIDS (OR = 1.46, 95% CI: 1.01 to 2.10), and having life goals (OR = 1.28, 95% CI: 1.10 to 1.48). Not using condoms during their first sexual encounter (OR = 0.61, 95% CI: 0.50 to 0.76), a history of unwanted sex (OR = 0.66, 95% CI: 0.51 to 0.86), and believing that condom use implies distrust in one's partner (OR = 0.57, 95% CI: 0.51 to 0.86) were factors associated with low self-efficacy among female respondents. Male respondents (n = 3519) with high self-efficacy were more likely to take HIV seriously (OR = 4.03, 95% CI: 1.55 to 10.52), to believe they are not at risk for HIV (OR = 1.38, 95% CI: 1.12 to 1.70), to report that getting condoms is easy (OR = 1.85, 95% CI: 1.23 to 2.77), and to have life goals (OR = 1.30, 95% CI: 1.10 to 1.54). Not using condoms during their first sexual experience (OR = 0.51, 95% CI: 0.39 to 0.67), a history of having unwanted sex (OR = 0.47, 95% CI: 0.34 to 0.64), believing condom use is a sign of not trusting one's partner (OR = 0.63, 95% CI: 0.46 to 0.87), and refusing to be friends with HIV-infected persons (OR = 0.52, 95% CI: 0.32 to 0.85) were factors associated with low self-efficacy among male respondents in the fully adjusted model. CONCLUSIONS: We used the social cognitive model (SCM) to identify factors associated with self-efficacy for condom use and sexual negotiation. Many of these factors are modifiable and suggest potential ways to improve self-efficacy and reduce HIV sexual risk behavior in South African youth.     

Brief report: condom use consistency associated with beliefs regarding HIV disease transmission among women receiving HIV antiretroviral therapy.

OBJECTIVE: To ascertain whether condom use consistency is associated with beliefs regarding a decreased likelihood of HIV transmission as a function of taking antiretroviral therapy. DESIGN: Cross-sectional analysis of HIV-positive women from Brooklyn (NY) enrolled in the Women's Interagency HIV Study (WIHS) who were taking any form of antiretroviral therapy at the time of data collection. METHODS: Between February and October, 1999, 145 HIV-positive eligible women participated in a structured, face-to-face interview. Interviews assessed attitudes and behaviors related to antiretroviral therapy and sexual risk behavior in the 6 months since a previous study visit. RESULTS: Over three fourths of the study sample (77%) disagreed with a statement that being on antiretroviral therapy decreases the chances of transmitting HIV to others. After controlling for number of sexual partners and HIV serostatus of partners, women reporting no association between HIV therapy and disease infectiousness were over three times more likely to report consistent condom use (odds ratio [OR], 3.1; 95% confidence interval [CI], 1.2-8.3; p <.05). CONCLUSIONS: Antiretroviral therapy may be associated with increased risk behavior when it is believed that regimens may decrease the risk of disease transmission. Education regarding potential deleterious consequences of inconsistent condom use should be part of ongoing HIV care.     

Reproductive history and allergic rhinitis among 31145 Danish women

BACKGROUND AND OBJECTIVE: A successful pregnancy is associated with a strong skewing of the immune system towards a Th2-type immune response. Because such a deviation is also the hallmark of allergic disease, it was investigated whether allergic rhinitis in women was associated with an increased likelihood of becoming pregnant and having a successful outcome of pregnancies. MATERIAL AND METHODS: Information on allergic rhinitis and reproductive history was obtained for 31145 pregnant women who participated in a national birth cohort study in Denmark during September 1997 to March 2000, and for whom complete information on siblings and place of residence and birth was available via the Civil Registration System. Data were analysed using logistic regression. RESULTS: Women who had previously been pregnant (OR = 0.91, 95% CI 0.85-0.98) or who had given birth previously (OR = 0.91, 95% CI 0.85-0.98) were less likely to report allergic rhinitis than others. The number of previous spontaneous abortions, gestational week of the first spontaneous abortion and fertility treatment were not associated with allergic rhinitis. Women who had waited less than a year to become pregnant more often had allergic rhinitis (OR = 1.18, 95% CI 1.06-1.32, P = 0.002) than women who had waited for more than a year. Early age at menarche was associated with an increased likelihood of allergic rhinitis (Ptrend = 0.003). CONCLUSIONS: Our findings did not support the hypothesis that an atopic genotype overall should be associated with an increased likelihood of successful outcome of pregnancies, but it might be associated with a decreased waiting time to pregnancy.     

Voluntary HIV counseling and testing: experience among the sexually active population in Bangui,Central African Republic

OBJECTIVES: In July 1997, the National Reference Center for Sexually Transmitted Diseases of Bangui, Central African Republic (CAR), was expanded by the creation of an anonymous and voluntary counseling and testing (VCT) unit for HIV infection, the Anonymous Surveillance Unit (Unité de Dépistage Anonyme [UDA]). The goal of the UDA was to initiate and promote voluntary HIV testing in the general adult population of Bangui. We carried out an observational and comprehensive survey over a 4-year period to document and analyze the experience of VCT in the UDA, with special attention to risk factors associated with HIV infection. METHODS: All clients for VCT were given adequate pretest counseling by trained counselors focused on knowledge about HIV infection and sexually transmitted infections, individual risks of acquiring HIV, and anticipation of the client's attitude about test results. After consent was obtained, a blood sample was drawn and tested for HIV by two ELISAs in parallel. The client paid a standard cost of $1.20 at the initial visit. After a week, test results were given to the client during the posttest visit, at which time HIV-seropositive individuals received emotional support and were referred to specific social or medical structures. Seronegative clients received reinforcement of prevention messages and were asked to come back for serologic follow-up free of charge after 3 (M3) and 12 (M12) months. RESULTS: From July 1997 to March 2001, 5686 individuals aged 14 to 65 years (mean age, 27 years) had an initial visit for VCT (V1). Peaks of UDA visitation (250-450 clients) were observed on the annual AIDS Day in the CAR, at which time HIV serologic testing was offered free of charge. A total of 5060 (89%) clients came back for a second visit (V2) to receive test results. Among those, 18.3% were infected with HIV type 1. Multivariate analysis of risk factors demonstrated marked association of HIV seropositivity with age, female gender, widowed/divorced women, poor or low education level, occupations such as civil servants or merchants, presence of symptoms of sexually transmitted infections, and lack of systematic condom use. Single young women were at higher risk for HIV infection compared with men of the same age (OR = 7.7 for women aged 15-24 years, 95% CI: 4.0-14.0; OR = 2.8 for women aged 25-34 years, 95% CI: 1.7-4.5). Widowed women older than 44 years of age were more likely to be HIV-seropositive than men (OR = 10.0; 95% CI: 1.7-83.6). A total of 885 (21%) HIV-seronegative individuals returned for follow-up at 3 months (M3; 0.45% rate of seroconversion). Seventy-nine (9%) individuals returned at 12 months (M12), without any new cases of HIV infection. HIV-negative clients consulting at M3 and M12 showed a significant reduction in unprotected intercourse with occasional sexual partners. CONCLUSION: This experience demonstrates that VCT for HIV infection is feasible in Central Africa.     

低出生体重儿的发生与母亲既往生育史的相关性分析

目的探讨母亲既往生育史对单胎活产低出生体重儿发生的影响因素。方法选取375名住院产妇所生的单胎活产低出生体重儿（LBW）,与同期分娩的单胎活产正常体重儿5157例进行病例对照分析,比较母亲既往生育史对低出生体重儿发生的影响。结果既往自然流产史、早产史和不良孕产史是LBW发生的危险因素（OR=1.57 95%CI1.110-2.25）、（OR=4.84 95%CI 2.01-11.66）、（OR=2.09 95%CI 1.22-3.57）,并且主要针对于早产LBW（OR=1.6595%CI 1.11-2.44）、（OR=6.55 95%CI 2.70-15.91）、（OR=2.18 95%CI 1.21-3.91）,既往低出生体重史是足月LBW发生的危险因素（OR=7.93 95%CI 1.72-36.46）结论 LBW的发生与既往自然流产史、早产史、不良孕产史、低出生体重史密切相关。对以上这些妇女再次怀孕的孕前、孕期均应做好保健服务,以有效减少LBW的发生。     

Exploring unsafe sexual practices among truck drivers at Meerut District,India: a cross-sectional study

BackgroundDespite implementation of HIV prevention programmes for truck drivers in India, unsafe sex behavior among truck drivers has been documented.ObjectiveThe objective of this study was to assess knowledge about HIV Transmission and modes of prevention, pattern of condom use with high risk partners and explore the practice of unsafe sex and its risk factors among truck drivers.MethodsThis exploratory cross-sectional study design was conducted on a recruited convenient sample of 100 truck drivers above 18 years from March to May 2015. Binary logistic regression was used to compute unadjusted odds ratio [95% Confidence Interval] for establishing association of risk factors with unsafe sex.ResultsOverall, only 7% had complete knowledge about HIV/AIDS transmission and prevention. 54% of truck drivers have sex with a high risk partner (commercial sexual worker or men having sex with men) and thirty-eight percent reported unsafe sexual practices due to inconsistent condom use with them. The various risk factors found significantly associated with unsafe sex were mean age of first intercourse (OR= 0.92, 95% CI: 0.75 – 0.97), access to pornography (OR = 4.4, 95% CI: 1.8 – 10.7) and conuming psychoactive substance before sex (OR = 4.06, 95% CI: 1.09 – 15.02).ConclusionSocio-demographic, occupational factors, pornography access and consuming psychoactive substances seems to influence the sexual behaviour of truckers.     

Predictors of failure to return for HIV test results among pregnant women in Moshi, Tanzania

Identification of HIV-infected women is a prerequisite in HIV perinatal prevention programs. The aim of this study was to determine the predictors of failure to return for HIV posttest results among pregnant women (N=2654) receiving antenatal care at primary health clinics in Moshi urban district, Tanzania. Consenting pregnant women, who were in the third trimester of pregnancy, received individual pretest counseling, followed by interview and screening for HIV. Posttest counseling and results were given after 1 week. A total of 182 (7%) failed to return for their HIV test results. Women were less likely to return for test results if their partners did not come for testing (adjusted odds ratio [AOR], 12.6; 95% CI, 3.1-51.4), if their partners consumed alcohol (AOR, 1.8; 95% CI, 1.3-2.7), and if they had never discussed reproductive health matters with their partners (AOR, 1.7; 95% CI, 1.1-2.7). Additionally, the site of recruitment, age, alcohol consumption, and advanced gestation age predicted failure to return for HIV test results. These results indicate that male partner factors were important in determining whether women returned for results. We therefore recommend promotion of antenatal couple counseling and strengthening of community awareness of the availability of perinatal interventions, with special efforts targeting men. Furthermore, the predictors for failure to collect test-results need to be addressed during pretest counseling.     

Effect of HIV infection on menstrual cycle length

HIV serostatus and menstrual function were examined using prospectively collected menstrual data from 802 HIV-seropositive and 273 HIV-seronegative women, ages 20 to 44, enrolled in two cohort studies of HIV infection in North American women. The associations between HIV serostatus and the probabilities of having a cycle lasting >40 days (n = 541 cycles), >90 days (n = 67 cycles), <18 days (n = 316 cycles) and mean length and variability of 18 to 40 day cycles (n = 3,634) were assessed. After adjustment for demographic characteristics, body mass index, and substance use, seropositivity increased the odds of having a very short cycle (< 18 days, odds ratio [OR], 1.45; 95% confidence interval [CI], 1.00-2.11) and a very long cycle (>90 days, OR, 1.32; 95% CI, 0.68-2.58) slightly, although the latter CIs include one. Seropositivity did not increase the odds of having a moderately long cycle (>40 days, OR, 1.14) or affect mean cycle length or variability (beta, 0.30 +/- 0.20; between-woman standard deviation [SD], 2.2 days [HIV-seronegative] and 1.9 days [HIV-seropositive]; within-woman SD, 3.5 days for both). Although seropositivity may slightly increase the probability of very short cycles, HIV serostatus has little overall effect on amenorrhea, menstrual cycle length, or variability. Among HIV-seropositive women, higher viral loads and lower CD4+ counts were associated with increased cycle variability and polymenorrhea.     

High HIV prevalence among a high-risk subgroup of women attending sexually transmitted infection clinics in Pune, India

OBJECTIVE: To investigate changes over a decade in prevalence and correlates of HIV among high-risk women attending sexually transmitted infection (STI) clinics in Pune, India, who deny a history of commercial sex work (CSW). DESIGN: Cross-sectional. METHODS: From 1993 to 2002, 2376 women attending 3 STI clinics in Pune were offered HIV screening. Women who denied CSW were included (n = 1020). RESULTS: Of 1020 women, 21% were HIV infected. The annual HIV prevalence increased from 14% in 1993 to 29% in 2001-2002 (P < 0.001). The change in HIV prevalence over time was paralleled by changes in clinic visitor characteristics; in later periods, women were older, more often employed, less likely to be currently married, and more likely to report condom use. In multivariate analysis, factors independently associated with HIV were calendar period (adjusted odds ratio [AOR], 1.9 for 1997-1999 vs. 1993-1996; 95% CI, 1.2-3.0; AOR, 2.3 for 2000-2002 vs. 1993-1996; 95% CI, 1.5-3.6), lack of formal education (AOR, 2.0; 95% CI, 1.4-2.9), having been widowed (AOR, 3.1; 95% CI, 1.6-6.1), current employment (AOR, 1.8; 95% CI, 1.2-2.6), and genital ulcer disease on examination (AOR, 1.8; 95% CI, 1.2-2.7). CONCLUSIONS: Women attending STI clinics in India who deny a history of CSW represent a small, hidden subgroup, likely put at risk for HIV because of high-risk behavior of their male partners, generally their husbands. Educational and awareness efforts that have targeted other subgroups in India (men and CSWs) should also focus on these hard-to-reach women. Risk reduction in this subgroup of Indian women would also be expected to reduce perinatal infections in India.     

Information and Communication Technology Use Among Low-Income Pregnant and Postpartum Women by Race and Ethnicity: A Cross-Sectional Study

BackgroundPregnancy and the postpartum period provide windows of opportunity to impact perinatal and lifelong preventive health behavior for women and their families, but these opportunities are often missed. Understanding racial/ethnic differences in information and communication technology (ICT) use could inform technology-based interventions in diverse populations.ObjectiveThe objective of the study was to evaluate differences in the use of ICT between racial and ethnic groups as well as by English language proficiency.MethodsWe conducted a cross-sectional study of 246 women who were aged 18 years or older and pregnant or within 1 year of delivery. They were recruited from 4 hospital-based outpatient clinics and completed a self-administered survey. We used multivariate regression analysis to evaluate the association between race/ethnicity and ICT (mobile phone/short message service [SMS] text message, Internet, and social network) usage by race/ethnicity and perceived English language proficiency after adjusting for age, income, marital status, and insurance status.ResultsIn all, 28% (69/246) of participants were Latina, 40% (98/246) were African American, 23% (56/246) were white, and 9% (23/246) from other racial/ethnic groups. Of the Latinas, 84% (58/69) reported limited English language proficiency and 59% (41/69) were uninsured. More than 90% of all participants reported mobile phone use, but more than 25% (65/246) had changed phone numbers 2 or more times in the past year. Compared to white women, African American women were less likely to SMS text message (OR 0.07, 95% CI 0.01-0.63) and Latinas were less likely to use the Internet to find others with similar concerns (OR 0.23, 95% CI 0.08-0.73). Women with limited English language proficiency were less likely to use the Internet overall (OR 0.30, 95% CI 0.09-0.99) or use email (OR 0.22, 95% CI 0.08-0.63) compared to women with adequate English language proficiency.ConclusionsMobile phones are widely available for the delivery of health interventions to low-income, racially diverse pregnant and postpartum women, but disparities in Internet use and SMS text messaging exist. Interventions or programs requiring Web-based apps may have lower uptake unless alternatives are available, such as those adapted for limited English proficiency populations.     

HIV-1 seroprevalence, risk factors, and preventive behaviors among women in northern Thailand

To study HIV-1 seroprevalence, risk factors, and preventive behaviors among reproductive-age women in northern Thailand, 804 consenting women who were identified postpartum or who were visiting family planning clinics were interviewed and tested during 1998 to 1999. Almost all women were currently married and had been pregnant more than once. Their median age was 27 years. HIV-1 seroprevalence was 3.1% overall and was higher in women aged between 25 and 29 years (5.9%), having had > or =2 lifetime sex partners (6.5%), or whose current marriage had lasted for < or =1 year (7.0%). No woman reported HIV risk factors other than heterosexual sex. Most (76%) HIV-infected women reported no casual sex partners and, therefore, had likely acquired the infection from their husbands. HIV testing and partner communications were common, but only 2% of couples used condoms consistently in the prior 6 months. Nearly half of these women perceived themselves at no or low risk for HIV infection; these women were less likely to have taken preventive actions. To prevent HIV transmission in stable partnerships in this population, additional efforts are needed to increase HIV testing and condom use, to improve women's negotiation skills, and to develop new methods that do not require partner cooperation such as vaginal microbicides or vaccines.     

HIV risk behaviors among African American men in Los Angeles County who self-identify as heterosexual

There are limited data on high-risk behaviors among heterosexual African American men with HIV infection. Risk behaviors were examined in a case-control study of HIV-infected (n = 90) and uninfected (n = 272) African American men who self-identified as heterosexual. Of men who self-identified as heterosexual, 31% (n = 28) of the infected men and 16% (n = 43) of the uninfected men reported having had anal sex with men. Among the heterosexual men reporting anal sex with men, 100% of the infected and 67% of the uninfected men reported inconsistent condom use during anal sex with men. Few of the infected (12%) and uninfected (2%) men reported oral sex with other men. Of the men who self-identified as heterosexual, 46% of those who were HIV-positive and 37% of those who were HIV-negative reported anal sex with women with infrequent condom use. An increasing risk for HIV was associated with decreasing age at first sexual experience (chi2, 9.3; p = .002). A history of injecting drugs (odds ratio [OR], 3.1; 95% confidence intervals [CIs], 1.8, 5.4) and amphetamine (OR, 4.3; 95% CIs, 1.1, 16.7) and methamphetamine (OR, 2.9; 95% CIs, 1.4, 6.3) use were associated with HIV. Innovative HIV prevention strategies are needed that move beyond the traditional gay versus straight model to effectively access hard-to-reach African American men who self-identify as heterosexual.     

Maternal characteristics associated with antenatal, intrapartum, and neonatal zidovudine use in four US cities, 1994-1998

OBJECTIVES: To evaluate implementation of 1994 United States Public Health Service guidelines for zidovudine (ZDV) use in HIV-infected women and their newborns by describing the prevalence of use of perinatal ZDV and other antiretrovirals and by investigating determinants of not receiving perinatal ZDV. DESIGN/METHODS: The Perinatal AIDS Collaborative Transmission Study is a prospective cohort study designed to collect information related to mother-to-child HIV transmission that was conducted in New York City (NY), Newark (NJ), Baltimore (MD), and Atlanta (GA), U.S.A. The current analysis was restricted to infants born between July 1994 and June 1998. RESULTS: Utilization rates for antenatal, intrapartum, and neonatal ZDV increased from 41% to 70% during the 4-year period. Use of combination antiretrovirals increased from fewer than 2% of women in 1994 to 1995 to 35% in 1997 to 1998. Antenatal and neonatal ZDV use increased each year, but intrapartum ZDV use reached a plateau after 1996. Mother-infant pairs with the following characteristics were less likely to have received a complete 3-part ZDV regimen: older maternal age, CD4 count >500 cells/microl, preterm birth, cocaine or heroin use during pregnancy, positive newborn drug screen test result, and smoking or alcohol use during pregnancy. By multivariate logistic regression adjusted for hospital and year of birth, cocaine or heroin use during pregnancy (odds ratio [OR], 2.3; 95% confidence interval [CI], 1.6-3.3), maternal CD4 count (OR, 0.4; 95% CI, 0.2-0.8; comparing <200 with >500 cells/microl), and preterm birth (OR, 1.6; 95% CI, 1.1-2.5) remained independently associated with not receiving the complete ZDV regimen. CONCLUSIONS: ZDV use by pregnant HIV-infected women and their infants has increased dramatically since publication of the 1994 guidelines. Nevertheless, women who abuse substances, give birth preterm, or have less advanced immunosuppression, were at substantial risk of not receiving the complete ZDV regimen.
