Evaluation of a community based waste oil recycling project in Temeke District, Dar es Salaam

This project is located in Temeke district and hosted by WAWEPA (Waste to Wealth Partners of Tanzania), which is the Non-Governmental Organization registered in 2006. Before the project implementation, A Community Needs Assessment was conducted by the researcher based on TEMO (Tanzania Environmental Management Organization) activities in the same District. TEMO is a non-registered community based organization dealing with waste oil management in Temeke District. The researcher conducted community needs assessment in order to evaluate factors influencing effectiveness of the Organization (TEMO), in operating waste oil management systems. The community needs assessment results and recommendations, form the basis of the waste oil recycling project implementation in the study area. The project implementation started by organizing the organization members and registering the organization as a Non -Governmental Organization, as such the Organization name changed from TEMO to WAWEPA and was officially registered under Non-Governmental Organization Act, 2002 on September 2006, by which, it was therefore, officially authorized as NGO, to deal with environmental management and protection activities.

Evaluation of the Universal Salt Iodization (USI) surveillance system in Tanzania, 2022.

BackgroundThe evaluation of surveillance systems has been recommended by the World Health Organization (WHO) to identify the performance and areas for improvement. Universal salt iodization (USI) as one of the surveillance systems in Tanzania needs periodic evaluation for its optimal function. This study aimed at evaluating the universal salt iodization (USI) surveillance system in Tanzania from January to December 2021 to find out if the system meets its intended objectives by evaluating its attributes as this was the first evaluation of the USI surveillance system since its establishment in 2010. The USI surveillance system is key for monitoring the performance towards the attainment of universal salt iodization (90%).MethodologyThis evaluation was guided by the Center for Disease Control Guidelines for Evaluating Public Health Surveillance Systems, (MMWR) to evaluate USI 2021 data. The study was conducted in Kigoma region in March 2022. Both Purposive and Convenient sampling was used to select the region, district, and ward for the study. The study involved reviewing documents used in the USI system and interviewing the key informants in the USI program. Data analysis was done by Microsoft Excel and presented in tables and graphs.ResultsA total of 1715 salt samples were collected in the year 2021 with 279 (16%) of non-iodized salt identified. The majority of the system attributes 66.7% had a good performance with a score of three, 22.2% had a moderate performance with a score of two and one attribute with poor performance with a score of one. Data quality, completeness and sensitivity were 100%, acceptability 91.6%, simplicity 83% were able to collect data on a single sample in 75% and the usefulness of the system had poor performance.ConclusionAlthough the system attributes were found to be working overall well, for proper surveillance of the USI system, the core attributes need to be strengthened. Key variables that measure the system performance must be included from the primary data source and well-integrated with the Local Government (district and regions) to Ministry of Health information systems

The prevalence and risk factors associated with Iron, vitamin B12 and folate deficiencies in pregnant women: A cross-sectional study in Mbeya, Tanzania.

Maternal nutrition is an important forecaster of infant's and mother's health status in most developing countries. This study aimed at assessing the prevalence and associated risk factors of iron, vitamin B12, and folate deficiencies among pregnant women in Mbeya Tanzania. A cross-sectional study using a cluster randomized sampling was conducted among 420 pregnant women. A structured questionnaire was used to collect socio-demographic and dietary assessment. Body iron store was assessed using serum ferritin measured by immunoturbidimetric assays using a Roche Cobas 400+ biochemistry analyzer. Serum folate was measured by folate microbiological assay, while serum vitamin B12 was measured by immunochemiluminescence assay using a Roche Cobas e411 immunoassay analyzer. Multivariate analysis was performed using Poisson regression. The prevalence of iron, folate, and vitamin B12 deficiencies among pregnant women in Mbeya was 37.8%, 24.0%, and 9.7% respectively. Higher odds of iron deficiency were seen in pregnant women aged 20-24 years older [Adjusted OR = 1.20 (95%CI 1.03, 1.35)], not employed [Adjusted OR = 3.0(95%CI 1.03-1.77)] and, not received iron/folic acid supplementation [Adjusted OR = 1.11 (95%CI 1.003-1.23)]. Pregnant women with highest and middle socio-economic statuses had lower odds of vitamin B12 deficiency [Adjusted OR = 0.83 (95%CI 0.76-0.92)] and [Adjusted OR = 0.89 (95%CI 0.81-0.98)] respectively. Pregnant women who were not employed, not received iron and folic acid supplement during pregnancy and, not consumed edible vegetable cooking oil had significant higher odds of serum folate deficiency [Adjusted OR = 3.0 (95%CI 1.58-5.68)], [Adjusted OR = 1.53 (95%CI 1.21-1.93)] and, [Adjusted OR = 2.77 (1.03-7.44)] respectively. This study confirms that iron, folate and vitamin B12 deficiencies are still a major challenge among pregnant women in Tanzania. We recommend for public health interventions for the provision of vitamin B12 along with iron and folic acid supplementations, especially in pregnant women belong to low socio-economic status and limited knowledge of healthy diet
