Predictors of herpes simplex virus type 2 prevalence and incidence among bar and hotel workers in Moshi, Tanzania.

BACKGROUND: Herpes simplex virus (HSV) type 2 increases the risk of human immunodeficiency virus (HIV) infection, and, in regions with high prevalence of both viruses, control of HSV-2 may be an effective method of HIV prevention. Identification of modifiable factors for prevention of HSV-2 infection is essential. We conducted this study among female bar and hotel workers in Moshi, Tanzania. METHODS: Factors associated with prevalent infection were examined among 1039 women. Predictors of incident infection were examined among 360 women initially HSV-2 negative, with at least 1 follow-up visit. RESULTS: HSV-2 prevalence was 56.3% (95% confidence interval [CI], 53.3%-59.3%). Only 2.5% of women able to name a sexually transmitted infection named herpes. Incidence was 14.2 cases/100 person-years (95% CI, 10.5-18.8 cases/100 person-years). Incident HSV-2 infection was independently associated with HIV infection, younger age of sexual initiation, ethnicity, alcohol consumption, and having a male partner with other sexual partners. CONCLUSIONS: The occurrence of HSV-2 is high in this population, but knowledge is low. Development of education programs to increase awareness of HSV-2 is critical. The control of both HSV-2 and HIV infections is a major public health priority in Moshi. Prevention interventions in this and other high prevalence populations might most effectively target younger women, before initiation of sexual activity.

Sexual behavior, psychosocial and knowledge differences between consistent, inconsistent and non-users of condoms: a study of female bar and hotel workers in Moshi, Tanzania.

Understanding psychosocial, sexual behavior and knowledge differences between never, inconsistent and consistent condom users can improve interventions to increase condom use in resource-poor countries, but they have not been adequately studied. We examined these differences in a cohort of 961 female hotel and bar workers in Moshi, Tanzania. Forty-nine percent of women reported no condom use; 39% reported inconsistent use, and 12% reported consistent use. Women with multiple sexual partners in the past five years were less likely to be consistent rather than inconsistent users as were women who had ever exchanged sex for gifts or money. Inconsistent users had higher condom knowledge and higher perceived acceptability of condom use than did never users, but they did not differ from consistent users by these factors. There are important differences between women by level of condom use. These findings can help inform interventions to increase condom use.

Human immunodeficiency virus type 1 among bar and hotel workers in northern Tanzania: the role of alcohol, sexual behavior, and herpes simplex virus type 2.

GOALS: We assessed baseline prevalence of human immunodeficiency virus type 1 (HIV-1) and other STDs, as well as behavioral and biologic risk factors for HIV-1 in a population of female bar/hotel workers in Moshi, Tanzania. STUDY DESIGN: Between 2002 and 2003, we enrolled 1042 female bar/hotel workers in an ongoing prospective cohort study. We analyzed data collected at baseline to assess the associations between alcohol, sexual behavior, STDs, and HIV-1 infection. RESULTS: The prevalence of HIV-1 infection was 19.0% (95% confidence interval [CI] = 16.6%-21.4%). Consistent condom use was low (11.1%). HIV-1 was associated with genital ulcers on examination (adjusted odds ratio [AOR] = 2.08, 95% CI = 1.16-3.74), herpes simplex virus type 2 (HSV-2) (AOR = 3.80, 95% CI = 2.42-5.97), and problem drinking (AOR = 1.92, 95% CI = 1.06-3.47). Other independent predictors of HIV-1 were increasing age, number of sex partners, cohabitating, formerly married, location of employment, and having a husband with another wife. CONCLUSIONS: These findings suggest that programs designed to control HSV-2, reduce the number of sexual partners and alcohol use, and promote condom use could be effective in reducing transmission of HIV-1 in this population.
