Exploring activities and behaviours potentially increases school-age children's vulnerability to malaria infections in south-eastern Tanzania.

BACKGROUND: Strengthening malaria control activities in Tanzania has dramatically declined human malaria infections. However, there is an increasing epidemiological shift in the burden on school-age children. The underlying causes for such an epidemiological shift remain unknown in this context. This study explored activities and behaviours that could increase the vulnerability of school-age children to transmission risk to provide insight into protection gap with existing interventions and opportunities for supplementary interventions. METHODS: This cross-sectional study conducted twenty-four focus group discussions (FGDs) in three districts of Rufiji, Kibiti and Kilwa in south-eastern Tanzania. Sixteen FGDs worked with school-age children (13 to 18 years) separating girls and boys and eight FGDs with their parents in mixed-gender groups. A total of 205 community members participated in FGDs across the study area. Of them, 72 participants were parents, while 133 were school-age children (65 boys and 68 girls). RESULTS: Routine domestic activities such as fetching water, washing kitchen utensils, cooking, and recreational activities such as playing and watching television and studying were the reported activities that kept school-age children outdoors early evening to night hours (between 18:00 and 23:00). Likewise, the social and cultural events including initiation ceremonies and livelihood activities also kept this age group outdoors from late evening to early night and sometimes past midnight hours. Parents migrating to farms from December to June, leaving behind school-age children unsupervised affecting their net use behaviour plus spending more time outdoors at night, and the behaviour of children sprawling legs and hands while sleeping inside treated bed nets were identified as potential risks to infectious mosquito bites. CONCLUSION: The risky activities, behaviours, and social events mostly occurring outdoors might increase school-age children's vulnerability to malaria infections. The findings provide preliminary insight on potential risk factors for persisting transmission. Further studies to quantify the risk behaviour and activities are recommended to establish the magnitude and anticipated impact on supplementary control strategies to control infection in school-age children.

Health insurance is important in improving maternal health service utilization in Tanzania-analysis of the 2011/2012 Tanzania HIV/AIDS and malaria indicator survey.

BACKGROUND: Maternal mortality rates vary significantly from region to region. Interventions such as early and planned antenatal care attendance and facility delivery with skilled health workers can potentially reduce maternal mortality rates. Several factors can be attributed to antenatal care attendance, or lack thereof, including the cost of health care services. The aim of this study was to examine the role of health insurance coverage in utilization of maternal health services in Tanzania. METHODS: Secondary data analysis was conducted on the nationally representative sample of men and women aged 15-49 years using the 2011/12 Tanzania HIV and Malaria Indicator Survey. It included 4513 women who had one or more live births within three years before the survey. The independent variable was health insurance coverage. Outcome variables included proper timing of the first antenatal care visit, completing the recommended number of antenatal care (ANC) visits, and giving birth under skilled worker. Data were analyzed both descriptively and using regression analyses to examine independent association of health insurance and maternal health services. RESULTS: Of 4513 women, only 281 (6.2%) had health insurance. Among all participants, only 16.9%, 7.1%, and 56.5%, respectively, made their first ANC visit as per recommendation, completed the recommended number of ANC visits, and had skilled birth assistance at delivery. A higher proportion of women with health insurance had a proper timing of 1st ANC attendance compared to their counterparts (27.0% vs. 16.0%, p < 0.001). Similar trend was for skilled birth attendance (77.6% vs. 55.1%, p < 0.001). After adjusting for other confounders and covariates, having health insurance was associated with proper timing of 1st ANC attendance (AOR = 1.89, p < 0.001) and skilled birth attendance (AOR = 2.01, p < 0.01). CONCLUSIONS: Health insurance coverage and maternal health services were low in this nationally representative sample in Tanzania. Women covered by health insurance were more likely to have proper timing of the first antenatal visit and receive skilled birth assistance at delivery. To improve maternal health, health insurance alone is however not enough. It is important to improve other pillars of health system to attain and sustain better maternal health in Tanzania and areas with similar contexts.

Effectiveness of community-based peer support for mothers to improve their breastfeeding practices: A systematic review and meta-analysis.

METHODS: We searched for evidence regarding community-based peer support for mothers in databases, such as PubMed/MEDLINE, the Cochrane Library, CINAHL, Web of Science, SocINDEX, and PsycINFO. We selected three outcome variables for breastfeeding practices, namely, exclusive breastfeeding duration, breastfeeding within the first hour of life, and prelacteal feeding. We conducted meta-analyses of the included randomized controlled trials and quasi-experimental studies. RESULTS: For our review, we selected 47 articles for synthesis out of 1,855 retrieved articles. In low- and middle-income countries, compared to usual care, community-based peer support increased exclusive breastfeeding at 3 months (RR: 1.90, 95% CI: 1.62-2.22), at 5 months (RR: 9.55, 95% CI: 6.65-13.70) and at 6 months (RR: 3.53, 95% CI: 2.49-5.00). In high-income countries, compared to usual care, peer support increased exclusive breastfeeding at 3 months (RR: 2.61, 95% CI: 1.15-5.95). In low- and middle-income countries, compared to usual care, peer support increased the initiation of breastfeeding within the first hour of life (RR: 1.51, 95% CI: 1.04-2.21) and decreased the risk of prelacteal feeding (RR: 0.38, 95% CI: 0.33-0.45). CONCLUSIONS: Community-based peer support for mothers is effective in increasing the duration of exclusive breastfeeding, particularly for infants aged 3-6 months in low- and middle-income countries. Such support also encourages mothers to initiate breastfeeding early and prevents newborn prelacteal feeding.

Association of opioid agonist therapy with the initiation of antiretroviral therapy - a systematic review.

OBJECTIVES: People who inject drugs are at high risk of HIV infection but often face barriers in accessing medical care including access to antiretroviral therapy (ART). Evidence is available about the effectiveness of opioid agonist therapy on drug dependency and risk behaviors. However, it remains scattered regarding access to ART among HIV-positive people who inject drugs. We conducted a systematic review to examine the association of opioid agonist therapy with ART initiation among HIV-positive people who inject drugs. METHODS: We searched the literature for evidence from seven databases. We conducted a narrative synthesis and meta-analysis to examine the association of opioid agonist therapy with ART initiation. RESULTS: Five out of 2,901 identified studies met the inclusion criteria. Three out of five studies reported that, HIV-positive people receiving opioid agonist therapy initiated ART more than those not receiving opioid agonist therapy. In meta-analysis, opioid agonist therapy was associated with ART initiation among HIV positive people who inject drugs (pooled odds ratio: 1.68; 95% confidence interval: 1.03-2.73). CONCLUSIONS: Opioid agonist therapy is positively associated with ART initiation among HIV-positive people who inject drugs. It is important to scale up opioid agonist therapy among people who inject drugs to improve their ART initiation.

A Mismatch between High-Risk Behaviors and Screening of Infectious Diseases among People Who Inject Drugs in Dar es Salaam, Tanzania.

BACKGROUND: People who inject drugs are at risk of various infectious diseases. Despite such a risk, evidence is limited which studied the utilization of screening services for common infectious diseases among people who inject drugs in Tanzania. We aimed to examine their high-risk behaviors; utilization of screening services for HIV infection, hepatitis B/C, any other sexually transmitted infection, and tuberculosis; and their associated factors in Dar es Salaam, Tanzania. METHODS: We conducted a baseline cross-sectional study as part of a prospective cohort study of people who inject drugs. We included 578 participants comprising of new enrollees of the integrated methadone-assisted treatment program and those who were selected from the communities but not enrolled in the program. We interviewed new enrollees preceding their enrollment and receipt of services from the program. We measured participants' high-risk behaviors and their utilization of screening services. We analyzed the data descriptively and used multiple logistic regressions to identify the factors associated with ever being screened for infectious diseases. RESULTS: Of 578 participants, 14.2% shared injection needles. Of 547 sexually active participants, 37.5% had multiple sexual partners and only 17.4% used a condom. Of all participants, however, only 36.0% had ever been screened for HIV infection, 18.5% for tuberculosis, 11.8% for any other sexually transmitted infection, and 11.6% for hepatitis B/C. They were more likely to have ever been screened for HIV infection if they had education levels above primary education (adjusted odds ratio [AOR]: 2.54, 95% CI: 1.54-4.20), had a history of transactional sex (OR: 2.63, 95% CI: 1.01-6.84), and were new enrollees of the program (AOR: 7.41, 95% CI: 4.41-12.86). CONCLUSIONS: People who inject drugs practice high-risk behaviors but their utilization of screening services for infectious diseases is poor in Dar es Salaam, Tanzania. It is crucial to increase the coverage of screening services for them and strengthen the counseling of safer sexual practices.

Correlates of health care seeking behaviour among people who inject drugs in Dar es Salaam, Tanzania.

BACKGROUND: People who inject drugs (PWID) suffer from a high burden of infectious disease. At the same time, they often have poor access to health care. As in other East African countries, the population of PWID is growing in Tanzania, but little is known about their contact with health care services. In this paper we examine patterns of health care use among PWID in Dar es Salaam and identify what factors are associated with regular contact with clinicians during illness. METHODS: We conducted a baseline cross-sectional study as part of a prospective cohort study involving PWID. We recruited 578 PWID, of whom 273 were newly enrolled on an integrated methadone-assisted treatment (MAT) program and 305 were community-recruited. At baseline, we interviewed the MAT program enrollees before they received services at the program clinics. We used bivariate and multiple logistic regression analyses to identify the factors associated with seeking medical care when ill. RESULTS: Only 25.4% of 578 participants reported seeing clinicians regularly when they needed medical care. Participants were more likely to see clinicians regularly if they were employed, (OR: 2.25, 95% CI: 1.28-3.98), had higher income levels (OR: 1.10, 95% CI: 1.00-1.22), were parents (OR: 1.71, 95% CI: 1.09-2.68), or knew where to seek affordable care (OR: 3.42, 95% CI: 2.12-5.52). CONCLUSION: PWID in Dar es Salaam generally did not seek health care when needed. To improve their health care seeking behaviour, it is important to advise PWID about where to seek affordable health care and to increase their income-generating skills.
