Nutritional Status and Other Baseline Predictors of Mortality among HIV-Infected Children Initiating Antiretroviral Therapy in Tanzania

BACKGROUND: We assembled a prospective cohort of 3144 children less than 15 years of age initiating antiretroviral therapy (ART) in Dar es Salaam, Tanzania. METHODS: The relationships of nutritional status and other baseline characteristics in relation to mortality were examined using Cox proportional hazards model. RESULTS: Compared with children with weight for age (WAZ) > -1, those with WAZ ≤ -2 to < -3 had a nearly double risk of death (relative risk [RR], 1.85; 95% confidence interval [CI], 1.10-3.11), and among those with WAZ ≤ -3, the risk more than tripled (RR, 3.36; 95% CI, 2.12-5.32). Other baseline risk factors for overall mortality included severe anemia (P < .001), severe immune suppression (P = .02), history of tuberculosis (P = .01), opportunistic infections (P < .001), living in the poorest district (P < .001), and advanced World Health Organization stage (P = .003). CONCLUSIONS: To sustain the obtained benefit of ART in this setting, interventions to improve nutritional status may be used as an adjunct to ART

Risky sexual practices among youth attending a sexually transmitted infection clinic in Dar es Salaam, Tanzania

\ud Youth have been reported to be at a higher risk of acquiring STIs with significant adverse health and social consequences. Knowledge on the prevailing risky practices is an essential tool to guide preventive strategies. Youth aged between 18 and 25 years attending an STI clinic were recruited. Social, sexual and demographic characteristics were elicited using a structured standard questionnaire. Blood samples were tested for syphilis and HIV infections. Urethral, high vaginal and cervical swabs were screened for common STI agents. A total of 304 youth were studied with mean age of 21.5 and 20.3 years for males and females respectively. 63.5% of youth were seeking STI care. The mean age of coitache was 16.4 and 16.2 years for males and females respectively. The first sexual partner was significantly older in females compared to male youth (23.0 vs 16.8 years) (p < 0.01). 93.2% of male youth reported more than one sexual lifetime partner compared to 63.0% of the females. Only 50% of males compared to 43% of females had ever used a condom and fewer than 8.3% of female youth used other contraceptive methods. 27.1% of pregnancies were unplanned and 60% of abortions were induced. 42.0% of female youth had received gifts/money for sexual favours. The HIV prevalence was 15.3% and 7.5% for females and males respectively. The prevalence of other STIs was relatively low. Among male youth, use of alcohol or illicit drugs was associated with increased risk of HIV infection. However, the age of sexual initiation, number of sexual partners or the age of the first sexual partner were not associated with increased risk of being HIV infected. Most female youth seen at the STI clinic had their first sexual intercourse with older males. Youth were engaging in high risk unprotected sexual practices which were predisposing them to STIs and unplanned pregnancies. There is a great need to establish more youth-friendly reproductive health clinics, encourage consistent and correct use of condoms, delay in sexual debut and avoid older sexual partners in females.\u

The aim of this study was to determine the factors underlying nonadherence measured by three methods. Patients and methods: This is a prospective longitudinal cohort of 220 patients on ART at Amana Hospital in Dar es Salaam, Tanzania. We measured adherence using a structured questionnaire combining a visual analog scale (VAS) and Swiss HIV Cohort Study Adherence Questionnaire (SHCS-AQ), pharmacy refill, and appointment keeping during four periods over 1 year. Overall adherence was calculated as the mean adherence for all time points over the 1 year of follow-up. At each time point, adherence was defined as achieving a validated cutoff for adherence previously defined for each method. Results: The proportion of overall adherence was 86.4% by VAS, 69% by SHCS-AQ, 79.8% by appointment keeping, and 51.8% by pharmacy refill. Forgetfulness was the major reported reason for patients to skip their medications. In multivariate analysis, significant predictors to good adherence were older age, less alcohol consumption, more advanced World Health Organization clinical staging, and having a lower body mass index with odds ratio (CI): 3.11 (1.55&ndash;6.93), 0.24 (0.09&ndash;0.62), 1.78 (1.14&ndash;2.84), and 0.93 (0.88&ndash;0.98), respectively. Conclusion: We found relatively good adherence to ART in this setting. Barriers to adherence include young age and perception of well-being.

Stress, motivation and professional satisfaction among health care workers in HIV/AIDS care and treatment centers in urban Tanzania: a cross-sectional study

Background: Shortages of health care workers (HCWs) represents a serious challenge to ensuring effective HIV care in resourcelimited settings (RLS). Stress, motivation, and job satisfaction have been linked with HCW retention and are important in addressing HCW shortages. In this cross-sectional study HCW stress, motivation and perceived ability to meet patient needs were assessed in PEPFAR-supported urban HIV care and treatment clinics (CTCs) in Tanzania.Methods: A self-administered questionnaire measuring motivation, stress, and perceived ability to and meet patient needs was given to HCWs at 16 CTCs. Scales measuring HCW satisfaction, motivation, and stress were developed using principle components analysis. Hierarchical linear models were used to explore the association of HCW and site characteristics with reported satisfaction, stress, motivation, and ability to meet patients’ needs.Results: Seventy-three percent (279) of HCWs completed the  questionnaire. Most (73%) HCWs reported minimal/no work-related stress, with 48% reporting good/excellent motivation, but 41% also reporting  feeling emotionally drained. Almost all (98%) reported feeling able to help their patients, with 68% reporting work as rewarding. Most reported receipt of training and supervision, with good availability of resources. In the  multivariate model, direct clinical providers reported lower motivation than management (p&lt;0.05) and HCWs at medium-sized sites reported higher motivation than HCWs at larger sites (p&lt;0.05). HCWs at small and medium sites were more likely to feel able to help patients than those from larger sites (p&lt;0.05 and p&lt;0.001 respectively).Conclusion: Despite significant patient loads, HCWs in these PEPFAR-supported CTCs reported high levels of motivation, job satisfaction, ability to meet patients’ needs, low levels of stress but significant emotional toll. Understanding the relationship between support systems such as strong supervision and training and these outcomes is critical in designing  interventions to improve motivation, reduce stress and increase retention of HCWs.KeyWords: HIV, motivation, stress, health care workers, resource limited setting

The willingness to participate in biomedical research involving human beings in low‐ and middle‐income countries: a systematic review

Objectives: To systematically review reasons for the willingness to participate in biomedical human subjects research in low- and middle-income countries (LMICs). Methods: Five databases were systematically searched for articles published between 2000 and 2017 containing the domain of ‘human subjects research’ in ‘LMICs’ and determinant ‘reasons for (non)participation’. Reasons mentioned were extracted, ranked and results narratively described. Results: Ninety-four articles were included, 44 qualitative and 50 mixed-methods studies. Altruism, personal health benefits, access to health care, monetary benefit, knowledge, social support and trust were the most important reasons for participation. Primary reasons for non-participation were safety concerns, inconvenience, stigmatisation, lack of social support, confidentiality concerns, physical pain, efficacy concerns and distrust. Stigmatisation was a major concern in relation to HIV research. Reasons were similar across different regions, gender, non-patient or patient participants and real or hypothetical study designs. Conclusions: Addressing factors that affect (non-)participation in the planning process and during the conduct of research may enhance voluntary consent to participation and reduce barriers for potential participants

Health-care worker engagement in HIV-related quality improvement in Dar es Salaam, Tanzania

To assess health-care worker (HCW) awareness, interest and engagement in quality improvement (QI) in HIV care sites in Tanzania. Cross-sectional survey distributed in May 2009. Sixteen urban HIV care sites in Dar es Salaam, Tanzania, 1 year after the introduction of a quality management program. Two hundred seventy-nine HCWs (direct care, clinical support staff and management). HCW perceptions of care delivered, rates of engagement, knowledge and interest in QI. HCW-identified barriers to and facilitators of the delivery of quality HIV care. Two hundred seventy-nine (73%) of 382 HCWs responded to the survey. Most (86%) felt able to meet clients' needs. HCW-identified facilitators of quality included: teamwork (88%), staff communication (79%), positive work environment (75%) and trainings (84%). Perceived barriers included: problems in patients' lives (73%) and too few staff or too high patient volumes (52%). Many HCWs knew about specific QI activities (52%) or had been asked for input on QI (63%), but fewer (40.5%) had participated in activities and only 20.1% were currently QI team members. Managers were more likely to report QI involvement than direct care or clinical support staff (P < 0.01). No difference in QI involvement was seen based on patient load or site type. HCWs can provide important insights into barriers and facilitators of providing quality care and can be effectively engaged in QI activities. HCW participation in efforts to improve services will ensure that HIV/AIDS quality of care is achieved and maintained as countries strive for universal antiretroviral access
