Violence is a risk factor for HIV infection that must be addressed through multilevel prevention approaches.

In view of the ever-increasing HIV/AIDS epidemic in sub-Saharan Africa, the expansion of HIV-1 voluntary counselling and testing (VCT) as an integral part of prevention strategies and medical research is both a reality and an urgent need. As the availability of HIV-1 VCT grows two limitations need to be addressed, namely: low rates of HIV-1 serostatus disclosure to sexual partners and negative outcomes of serostatus disclosure. Results from a study among men, women and couples at an HIV-1 VCT clinic in Dar es Salaam, Tanzania are presented. The individual, relational and environmental factors that influence the decision to test for HIV-1 and to share test results with partners are described. The most salient barriers to HIV-1 testing and serostatus disclosure described by women include fear of partners' reaction, decision-making and communication patterns between partners, and partners' attitudes towards HIV-1 testing. Perception of personal risk for HIV-1 is the major factor driving women to overcome barriers to HIV-1 testing. The implications of findings for the promotion of HIV-1 VCT programmes, the implementation of partner notification policies and the development of post-test support services are discussed.

A random cluster sample survey of approximately 18,000 people in 11 villages was performed in Ulanga, a Tanzanian district with a population of approximately 139,000 people. Well-instructed fourth-year medical students and neurologic and psychiatry nurses identified persons with epilepsy using a screening questionnaire and sent them to a neurologist for detailed evaluation. Identified were 207 subjects (88 male, 119 female) with epilepsy; of these, 185 (89.4%) (80 male, 105 female) had active epilepsy. The prevalence of active epilepsy was 10.2 in 1,000. Prevalence among villages varied, ranging from 5.1 to 37.1 in 1,000 (age-adjusted 5.8-37.0). In a 10-year period (1979-1988) 122 subjects living in the 11 villages developed epilepsy, with an annual incidence of 73.3 in 100,000. Generalized tonic-clonic seizures (GTCS) accounted for 58% and partial seizures accounted for 31.9%, whereas in 10.1% seizures were unclassifiable. Of the partial seizures, secondarily generalized seizures were the most common. Possible etiologic or associated factors were identifiable in only 25.3% of cases. Febrile convulsions were associated in 13.4 of cases. Other associated factors included unspecified encephalitis (4.7%), cerebral malaria (1.9%), birth injury (1.4%), and other (3%). In 38% of the cases, there was a positive family history of epilepsy.

The rates, barriers, and outcomes of HIV serostatus disclosure to sexual partners are described for 245 female voluntary counseling and testing (VCT) clients in Dar es Salaam, Tanzania. VCT clients were surveyed 3 months after HIV testing to describe their HIV-serostatus disclosure experiences. Sixty-four percent of HIV-positive women and 79.5% of HIV-negative women (p = 0.028) reported that they had shared HIV test results with their partners. Among women who did not disclose, 52% reported the reason as fear of their partner's reaction. Both 81.9% of HIV-negative women and 48.9% of HIV-positive women reported that their partner reacted supportively to disclosure (p < 0.001). Less than 5% of women reported any negative reactions following disclosure. VCT should continue to be widely promoted. However, intervention approaches such as development of screening tools and new counseling approaches are important to ensure the safety of women who want to safely disclose HIV serostatus to their sexual partners.

HIV risk through needle sharing is now an emerging phenomenon in Africa. This article describes the practices that heroin users are producing as they establish the rules and organization surrounding their drug use. Their practices and interactions reveal the ways that they become initiated into its use, how they progress to injecting, and the important role of local neighbourhood hangouts in facilitating this process. Their practices, interactions and narratives also provide insights into what may be the most appropriate HIV-prevention interventions. Semi-structured interviews were conducted during the months of February and July 2003 with 51 male and female injectors residing in 8 neighbourhoods in the Dar es Salaam, Tanzania. Interviews were content coded and codes were collapsed into emergent themes around hangout places, initiation of heroin use, and progression to injecting. Interviews reveal that Dar es Salaam injectors begin smoking heroin in hangout areas with their friends, either because of peer pressure, desire, or trickery. One hangout place in particular, referred to as the 'geto' (ghetto) is the main place where the organization and rules governing heroin use are produced. Three main types of heroin 'ghettoes' are operating in Dar es Salaam. As users build a tolerance for the drug they move along a continuum of practices until they begin to inject. Injecting heroin is a comparatively recent practice in Africa and coincides with: (1) Tanzania transitioning to becoming a heroin consuming community; (2) the growing importance of youth culture; (3) the technical innovation of injecting practices and the introduction and ease of use of white heroin; and (4) heroin smokers, sniffers, and inhalers perceived need to escalate their use through a more effective and satisfying form of heroin ingestion.

Before a health education program can be established, one must first know what the target population believes and does with respect to the disease in question. Therefore, we performed a study among Tanzanian rural inhabitants to identify their knowledge, attitude, and practice (KAP) toward epilepsy: 3,256 heads of households (mean age 40.2 years, range 15-90 years; M/F ratio 1:1) were interviewed. Of the respondents, 32.9% said they had never seen a seizure; 67.7% said they did not know the cause of epilepsy; 33.3% mentioned various causes including heredity, witchcraft, infection of the spinal cord, hernia; 40.6% believed epilepsy was infectious through physical contact, flatus, breath, excretions, sharing food; 36.8% believed epilepsy could not be cured and 17.1% believed it could not even be controlled; 45.3% believed epilepsy could be treated by traditional healers, and only 50.8% believed hospital drugs were of any use; and 62.7% of the respondents would not allow an epileptic child to go to school for various reasons, including mental subnormality (54.0%), fear of the child falling while alone (65.9%), and fear that the epileptic child would infect other children (11.2%). Concerning what is to be done when a seizure occurs, 33.5% of the respondents would keep away and not touch the person; 16.5% would take some potentially harmful measure such as forcing a mouth gag or forcing a drink such as water (1 even mentioned urine); 5.2% would take unnecessary measures such as rushing the patient to a hospital. Only 35.7% of respondents would perform at least some of the currently recommended first-aid measures.(ABSTRACT TRUNCATED AT 250 WORDS)

Depression during pregnancy may negatively influence social functioning, birth outcomes and postnatal mental health. A cross-sectional analysis of the baseline survey of a prospective study was undertaken with an objective of determining the prevalence and socio-demographic factors associated with depressive morbidity during pregnancy in a Tanzanian peri-urban setting. Seven hundred and eighty seven second to third trimester pregnant women were recruited at booking for antenatal care at two primary health care clinics. Prenatal structured interviews assessed socioeconomic, quality of partner relationships and selected physical health measures. Depressive symptoms were measured at recruitment and three and eight months postpartum using the Kiswahili version of the Hopkins Symptom Checklist. Completed antenatal measures available for 76.2% participants, showed a 39.5% prevalence of depression. Having a previous depressive episode (OR 4.35, P<0.01), low (OR 2.18, P<0.01) or moderate (OR 1.86, P=0.04) satisfaction with ability to access basic needs, conflicts with the current partner (OR 1.89, P<0.01), or booking earlier for antenatal care (OR 1.87, P=0.02) were independent predictors of antenatal depression in the logistic regression model; together explaining 21% of variance in depression scores. Attenuation of strength of multivariate associations suggests confounding between the independent risk factors and sociodemographic and economic measures. In conclusion, clinically significant depressive symptoms are common in mid and late trimester antenatal clinic attendees. Interventions for early recognition of depression should target women with a history of previous depressive episodes or low satisfaction with ability to access basic needs, conflict in partner relationships and relatively earlier booking for antenatal care. Findings support a recommendation that antenatal services consider integrating screening for depression in routine antenatal care.

Injection drug use has recently emerged in sub-Saharan Africa. The purpose of this study was to assess the factors associated with increased risk of testing HIV-positive in a sample of injection drug users (IDUs) in Dar es Salaam, Tanzania. Participants were recruited by a trained outreach worker or were referred by IDUs who had completed the study. Blood specimens and self-reported socioeconomic and behavioral data were collected from 315 male and 219 female IDUs. Data were analyzed using univariate odds ratios and multivariate logistic regression modeling. Forty-two percent of the sample tested HIV-positive. Several socioeconomic, injection, and sexual factors were found to be associated with increased odds of testing HIV-positive. Multivariate analysis showed that having had sex more than 81 times in past 30 days, earning less than 100,000 shillings (US$76) in the past month, residency in Dar es Salaam for less than 5 years, and injecting for 3 years were independently associated with the greatest risk of infection. The rate of HIV infection in this sample of IDUs was found to be very high, suggesting that injection drug use may be a factor in the continuing epidemic in sub-Saharan Africa. The factors associated with increased risk of HIV infection suggest further research is needed on the needle use and sexual networks of IDUs.
