    Colorectal cancer (CRC) is a growing public health concern with increasing rates in countries with previously known low incidence. This study determined pattern and distribution of CRC in Tanzania and identified hot spots in case distribution. Methods. A retrospective chart audit reviewed hospital registers and patient files from two national institutions. Descriptive statistics, Chi square (x2) tests, and regression analyses were employed and augmented by data visualization to display risk variable differences. Results. CRC cases increased sixfold in the last decade in Tanzania. There was a 1.5% decrease in incidences levels of rectal cancer and 2% increase for colon cancer every year from 2005 to 2015. Nearly half of patients listed Dar es Salaam as their primary residence. CRC was equally distributed between males (50.06%) and females (49.94%), although gender likelihood of diagnosis type (i.e., rectal or colon) was significantly different (P=0.027). More than 60% of patients were between 40 and 69 years. Conclusions. Age (P=0.0183) and time (P=0.004) but not gender (P=0.0864) were significantly associated with rectal cancer in a retrospective study in Tanzania. Gender (P=0.0405), age (P=0.0015), and time (P=0.0075) were all significantly associated with colon cancer in this study. This retrospective study found that colon cancer is more prevalent among males at a relatively younger age than rectal cancer. Further, our study showed that although more patients were diagnosed with rectal cancer, the trend has shown that colon cancer is increasing at a faster rate.

    Tanzania has a double burden of malnutrition, including a high prevalence of undernutrition and an increasing prevalence of overweight and obesity among adolescents. Schools present a valuable opportunity to reach a large section of the country’s adolescent population with nutrition-oriented interventions. The objective of this study was to assess the current state of adolescent school nutrition interventions in Dodoma, Tanzania, with emphasis on 3 potential school-based nutrition interventions, school vegetable gardens, school meals, and education (on nutrition, agriculture, and water, sanitation, and hygiene). Focus group discussions were conducted with several regional and district-level governmental stakeholders, including health, education, and agricultural officers. Ten public secondary schools were visited, and interviews with school administrators, teachers, students, and parents were conducted. All stakeholders interviewed supported interventions to improve school-based nutrition, including school gardens, school feeding, and nutrition education. All 10 schools visited had some experience providing school meals, but parents’ contributions were essential for the program’s sustainability. Most schools visited had land available for a school garden program, but water availability could be challenging during certain times of the year. The teachers interviewed expressed that the curriculum on nutrition education was highly theoretical and did not allow students to practice the knowledge and skills they learned in the classroom. The current school-based approach to tackling the double burden of adolescent malnutrition in Dodoma is localized and ad hoc. To leverage the potential of schools as a platform for nutrition interventions, integrated and policy-mandated interventions are needed.
