Sustaining LLIN coverage with continuous distribution: the school net programme in Tanzania.

Most malaria-endemic countries have struggled in the past decade to establish effective national-scale continuous distribution mechanisms for long-lasting insecticidal nets (LLINs). Since the implementation of the Tanzania National Voucher Scheme in 2004 and mass-distribution campaigns in 2009-2011 and 2015-2016, Tanzania has been committed to finding new and innovative ways of achieving and maintaining universal bed net coverage. Planning for the School Net Programme (SNP) began in 2011 and in 2013, the country piloted a SNP in three regions. Nets were distributed annually to children attending schools in selected primary and secondary grades. Intra-family re-distribution was assumed, and hence the family as a whole, rather than just the children themselves, were the targeted beneficiaries. The programme has since expanded to 14 regions and has seen six rounds of annual distribution. In its fifth year, 3 million nets were distributed at a cost of USD 3.64 per net and USD 0.60 per person-year of protection (including the net). ITN access and use were maintained at a high level (~ 50-75%) over the first 4 years of distribution within selected evaluation areas, even in the absence of a mass distribution event. Net distribution through primary schools has proven to be a feasible and effective strategy for maintaining consistently high coverage in Tanzania.

Determining the Impact of the COVID-19 Pandemic on Availability, Use, and Readiness of Family Planning and Contraceptive Services at Selected Primary Health Care Facilities in Africa and Asia: Protocol for a Mixed Methods Study.

BACKGROUND: The COVID-19 pandemic and the associated social restrictions may have disrupted the provision of essential services, including family planning (FP) and contraceptive services. This protocol is adapted from a generic study protocol titled "Health systems analysis and evaluations of the barriers to availability and readiness of sexual and reproductive health services in COVID-19 affected areas," conducted by the World Health Organization (WHO) Department of Reproductive Health and Research. OBJECTIVE: This study aims to assess the availability and use of FP and contraceptive services in primary health facilities during and after the COVID-19 pandemic; assess the risk perceptions of COVID-19 stigma, barriers to access, and quality of services from clients' and providers' perspectives in the COVID-19-affected areas; and assess the postpandemic recovery of the facilities in the provision of FP and contraceptive services. METHODS: In-depth interviews will be conducted with clients-women in the reproductive age group and their male partners who visit the selected health facilities for FP and contraceptive services-and health providers (the most knowledgeable person on FP and contraceptive service provision) at the selected health facilities. Focus group discussions will be conducted with clients at the selected health facilities and in the community. The in-depth interviews and focus group discussions will help to understand clients' and health service providers' perspectives of FP and contraceptive service availability and readiness in COVID-19-affected areas. A cross-sectional health facility assessment will be conducted in all the selected health facilities to determine the health facility infrastructure's ability and readiness to provide FP and contraceptive services and to capture the trends in FP and contraceptive services available during the COVID-19 pandemic. Scientific approval for this study is obtained from the WHO Research Project Review Panel, and the WHO Ethics Review Committee has given ethical approval in the 3 countries. RESULTS: Using a standardized research protocol will ensure that the results from this study can be compared across regions and countries. The study was funded in March 2021. It received ethics approval from the WHO Ethics Review Committee in February 2022. We completed data collection in September 2022. We plan to complete the data analysis by March 2023. We plan to publish the study results by Summer 2023. CONCLUSIONS: The findings from this study will provide a better understanding of the impact of the COVID-19 pandemic on FP and contraceptive services at the facility level, which will help policy makers and health managers develop and strengthen FP policies and services in health facilities to be more responsive to community needs.

Evaluation of long-lasting insecticidal net distribution through schools in Southern Tanzania.

Universal coverage with effective vector control remains the mainstay of malaria vector control in sub-Saharan Africa. Tanzania has utilized a number of mechanisms for the maintenance of long-lasting insecticidal net (LLIN) coverage over time. Schools have been identified as one potential channel for continuous distribution of LLIN. This research aims to evaluate an annual school-based LLIN distribution programme in Tanzania that began in 2013, called the School Net Programme (SNP). Following each of the first four rounds of SNP distribution, a household survey was conducted in intervention and comparison districts in Southern and Lake zones of Tanzania (N = 5083 households). Measures of ownership, access and use were compared between intervention and comparison districts. Determinants of reach were assessed in intervention districts. Population access to an LLIN increased from 63.1% (95% CI: 58.8, 67.5) to 76.5% (95% CI: 72.9, 80.0) in the intervention districts between the first and last surveys. Access also rose in the comparison districts from 51.4% (95% CI: 46.9, 55.9) to 79.8% (95% CI: 77.3, 82.0) following mass distribution and implementation of school-based distribution during the study period. LLIN use increased in intervention districts from 44.9% (95% CI: 40.5, 49.3) to 65.6% (95% CI: 59.4, 71.8) and from 57.2% (95% CI: 49.7, 64.7) to 77.4% (95% CI: 69.3, 85.5) specifically amongst primary school-aged children. Households reached by the SNP were wealthier households with children enrolled in school. The SNP in Tanzania was able to maintain population level LLIN ownership, use and access in the absence of mass distribution. The SNP successfully reached households that housed school-aged children. Alternative delivery strategies may need to be considered to reach households without children enrolled in schools that experienced fewer benefits from the programme.

A comparative analysis of determinants of low birth weight and stunting among under five children of adolescent and non-adolescent mothers using 2015/16 Tanzania Demographic and Health Survey (TDHS).

BACKGROUND: Tanzania is one of the Sub-Saharan African country with nearly 12 out of 60 million people being adolescent. The prevalence of child marriage is higher with one out of every three girls being married before reaching their 18th birthday, 5 % being married by the age of 15, and 31% by the age of 18 years. Literature shows early pregnancy is associated with Low Birth Weight (LBW) and stunting among children under 5 years. This paper explores variation and factors associated with low birth weight and stunting among children born by adolescent and non-adolescent mothers. METHODS: Data from 13,266 women with children under 5 years collected as part of the 2015/2016 TDHS was re-analyzed using STATA version 14 software while accounting for survey design. A total of 6385 women (of which 7.2% were adolescent) and 8852 women (of which 6.7% were adolescent) were involved in the analysis of child birth weight and stunting respectively. Descriptive statistics stratified by maternal age was conducted with LBW and stunting as outcome variables followed by logistic regressions models controlling for confounding variables. RESULTS: The proportion of obese or overweight adolescent and non-adolescent mothers was 11.8 and 36.5% respectively. Antenatal care (ANC) attendance, areas of residence and social economic status were very similar in the two maternal age groups. Non- adolescent mothers had reduced odds of giving birth to LBW babies compared to adolescent mothers (Adjusted Odds Ratio (AOR) = 0.34; 95% CI: 0.22-0.50). Maternal undernutrition (AOR = 2.29; 95% CI: 1.43-3.67), being divorced, separated or widowed (AOR = 1.76; 95% CI: 1.24-2.50) and having at least four ANC visits (AOR = 0.64; 95% CI: 0.49-0.83) were significantly associated with reduced odds of having a LBW. Child stunting was not associated with maternal age. Maternal high socioeconomic status (AOR = 0.69; 95% CI: 0.57-0.84) and maternal obesity or overweight (AOR = 0.77; 95% CI: 0.64-0.92) were negatively associated with stunting. Child birth weight, sex, and age were significantly associated with stunting. CONCLUSION: Maternal age was a predictor of LBW but not stunting. ANC attendance and not living with a spouse increase the risk of LBW babies. Stunting was associated with low maternal body mass index (BMI), low socioeconomic status, child birth weight, gender, and age. A multi-sectoral approach is needed to address child nutrition problems with teenagers 'specific intervention that offer emotional support, and health education during pregnancies for improving immediate and later life child birth outcomes.

Prevalence and Determinants of Undernutrition among 6- to 59-Months-Old Children in Lowland and Highland Areas in Kilosa District, Tanzania: A Cross-Sectional Study.

BACKGROUND: Undernutrition is the most dominant form of malnutrition among children in developing countries. Studies conducted in Tanzania have reported high levels of undernutrition among children below five years of age. However, there is limited information on differences in stunting prevalence across agroecological zones. This study aimed to determine the prevalence of undernutrition and its determinants in the lowland and highland areas in Kilosa District, Tanzania. METHODS: A cross-sectional study was conducted in a sample of 200 randomly selected households from the lowland and 141 from the highland areas of Kilosa District in Morogoro Region, Tanzania. Sociodemographic, feeding practices, hygiene, and sanitation data were collected using a structured questionnaire. Weight and height of children were measured using a standard procedure, and age was calculated from the birth date obtained from the child growth card. Anthropometric data were analyzed by using Emergency Nutrition Assessment (ENA) software. The logistic regression model was used to explore the determinants of undernutrition. RESULTS: Prevalence of stunting, underweight, and wasting was 41.0%, 11.5%, and 2.5% in lowland and 64.5%, 22.0%, and 1.4% in highland areas, respectively. The prevalence of stunting and underweight was higher in the highland compared to the lowland areas (p < 0.001). Significant determinants of underweight were areas of residence (AOR 4.21, 95% CI: 1.62-10.9), age of the children (AOR 5.85, 95% CI: 1.81-18.97), and child birth weight (AOR, 4.98 95% CI: 1.65-15.05), while determinants of stunting were the area of residence (AOR, 2.77 95% CI: 1.43-5.36), maternal age (AOR, 0.33 95% CI: 0.14-0.79), sex of a child (AOR, 1.89 95% CI: 1.03-3.50), and child birth weight (AOR, 3.29 95% CI: 1.21-8.97). CONCLUSION: The prevalence of undernutrition, especially stunting and underweight, was high in the study areas. Determinants of stunting differed between highlands and lowland areas, highlighting the needs of having properly integrated interventions based on the geographical location.

Effectiveness of integrated nutrition interventions on childhood stunting: a quasi-experimental evaluation design.

BACKGROUND: Although malnutrition particularly stunting is recognized as multi-causal, there has been limited integrated nutrition interventions to reduce its burden in children under-fives and those existing are not well evaluated. This study tested the effectiveness of provision of health and nutrition education and promotion of home gardening in child stunting. METHODS: The study used a quasi-experimental evaluation design. Two rounds of household surveys were done to assess changes in behaviors (uptake of Antenatal Care services and child feeding practices) and stunting among children under-5 years. The sample size was calculated to detect a 10% percent absolute baseline-to-end-line change in stunting. A two-stage stratified sampling process was used to sample 896 and 1736 households at each round of data collection in the intervention and control districts respectively. Mothers delivered in the past 24 months preceding the survey and all children under-5 years residing in selected households were eligible. The difference in difference (DID) analysis was used to estimate effect of the interventions. All ethical clearances were obtained from relevant authorities prior to data collection. RESULTS: A total of 3467 and 4145 children under 5 years were recruited at baseline and endline respectively. The proportional of stunted children decreases from 35.9 to 34.2% in intervention and from 29.3 to 26.8% in the control sites. Overall, no statistically significant stunting reduction was observed between intervention and control sites. However, a significant effect was observed in intermediate outcomes; Uptake of iron folic acid (DID: 5.2%, (95% CI: 1.7-8.7), p = 0.003), health facility delivery (DID: 6.5%, (95% CI: 1.8-11.2), p = 0.006), pre-lacteal feeding (DID: - 5.9%, (95%CI: - 9.2, - 2.5), p = 0.001), breast feeding within 1 h after birth (DID: 7.8%, (95%CI: 2.2-13.4), p = 0.006) and exclusive breast feeding in children under 6 months (DID:20.3%, (95% CI: 10.5-30.1), p = 0.001). CONCLUSION: The 3 years program did not result in significant evidence of stunting reduction, but the observed effect on health and nutrition behavioural indicators are at the causal pathways to improved child nutritional outcomes in the long run. Implementation of these integrated packages over a longer duration is needed to witness significant reduction in the prevalence of stunting.

Adherence to Iron-Folic Acid Supplementation and Associated Factors among Pregnant Women in Kasulu Communities in North-Western Tanzania.

INTRODUCTION: Pregnant women are at a high risk of anaemia, with iron-folate deficiency being the most common cause of anaemia among pregnant women. Despite the well-known importance of iron and folic acid supplementation (IFAS) during pregnancy, adherence to these supplements is relatively low and associated factors were not well identified in the study area. This study is aimed at investigating adherence to IFAS and associated factors among pregnant women in Kasulu district, north-western Tanzania. METHODS: A health facility cross-sectional survey with a mixed-method approach was conducted in Kasulu district from March to April 2019. A structured questionnaire was given to 320 women with children aged 0-6 months to assess factors associated with adherence to IFAS among pregnant women. Data were entered into SPSS version 22.0 for analysis. Binary logistic regression was further employed to determine the factors associated with adherence to IFAS. Focus group discussions were done with 19 pregnant women and 15 mothers of children aged 0-6 months to obtain more clarifications on the factors associated with adherence to IFAS. Furthermore, in-depth interviews were done with six health care providers to explore their perceptions of IFAS. RESULTS: Out of the 320 respondents of the survey, 20.3% (n = 65) adhered to IFAS. Factors associated with adherence to IFAS among pregnant women included time to start ANC (AOR = 3.72, 95% CI: 1.42, 9.79), knowledge of anaemia (AOR = 3.84, 95% CI: 1.335, 10.66), counseling on the importance of the iron-folic acid (AOR = 3.86, 95% CI: 1.42, 10.50), IFAS given during clinical visit (AOR = 15.72, 95% CI: 5.34, 46.31), number of meals consumed (AOR = 3.44, 95% CI: 1.28, 9.21), number of children (AOR = 3.462, 95% CI: 1.035, 11.58), and distance to health facility (AOR = 0.34, 95% CI: 0.131, 0.886). Qualitative findings revealed that delayed first ANC visit, lack of remainder for pregnant women to take IFAS, low awareness about the negative effects of anaemia, low of knowledge of IFAS and management of side effects, negative beliefs about the use of IFAS, and follow-up mechanism were major reasons for poor adherence. CONCLUSION: Adherence to iron-folic acid supplementation during pregnancy was low. Strengthening systems for creating reminding mechanism, raising community awareness through educational programs to pregnant women and health providers could improve adherence to IFAS.

Multivitamin and iron supplementation to prevent periconceptional anemia in rural tanzanian women: a randomized, controlled trial.

OBJECTIVE: Women's nutritional status during conception and early pregnancy can influence maternal and infant outcomes. This study examined the efficacy of pre-pregnancy supplementation with iron and multivitamins to reduce the prevalence of anemia during the periconceptional period among rural Tanzanian women and adolescent girls. DESIGN: A double-blind, randomized controlled trial was conducted in which participants were individually randomized to receive daily oral supplements of folic acid alone, folic acid and iron, or folic acid, iron, and vitamins A, B-complex, C, and E at approximately single recommended dietary allowance (RDA) doses for six months. SETTING: Rural Rufiji District, Tanzania. SUBJECTS: Non-pregnant women and adolescent girls aged 15-29 years (n = 802). RESULTS: The study arms were comparable in demographic and socioeconomic characteristics, food security, nutritional status, pregnancy history, and compliance with the regimen (p>0.05). In total, 561 participants (70%) completed the study and were included in the intention-to-treat analysis. Hemoglobin levels were not different across treatments (median: 11.1 g/dL, Q1-Q3: 10.0-12.4 g/dL, p = 0.65). However, compared with the folic acid arm (28%), there was a significant reduction in the risk of hypochromic microcytic anemia in the folic acid and iron arm (17%, RR: 0.61, 95% CI: 0.42-0.90, p = 0.01) and the folic acid, iron, and multivitamin arm (19%, RR: 0.66, 95% CI: 0.45-0.96, p = 0.03). Inverse probability of treatment weighting (IPTW) to adjust for potential selection bias due to loss to follow-up did not materially change these results. The effect of the regimens was not modified by frequency of household meat consumption, baseline underweight status, parity, breastfeeding status, or level of compliance (in all cases, p for interaction>0.2). CONCLUSIONS: Daily oral supplementation with iron and folic acid among women and adolescents prior to pregnancy reduces risk of anemia. The potential benefits of supplementation on the risk of periconceptional anemia and adverse pregnancy outcomes warrant investigation in larger studies.
