The nutritional quality of cereals varies geospatially in Ethiopia and Malawi.

ABSTRACT: Micronutrient deficiencies (MNDs) remain widespread among people in sub-Saharan Africa^1-5, where access to sufficient food from plant and animal sources that is rich in micronutrients (vitamins and minerals) is limited due to socioeconomic and geographical reasons^4-6. Here we report the micronutrient composition (calcium, iron, selenium and zinc) of staple cereal grains for most of the cereal production areas in Ethiopia and Malawi. We show that there is geospatial variation in the composition of micronutrients that is nutritionally important at subnational scales. Soil and environmental covariates of grain micronutrient concentrations included soil pH, soil organic matter, temperature, rainfall and topography, which were specific to micronutrient and crop type. For rural households consuming locally sourced food-including many smallholder farming communities-the location of residence can be the largest influencing factor in determining the dietary intake of micronutrients from cereals. Positive relationships between the concentration of selenium in grain and biomarkers of selenium dietary status occur in both countries. Surveillance of MNDs on the basis of biomarkers of status and dietary intakes from national- and regional-scale food-composition data^1-7 could be improved using subnational data on the composition of grain micronutrients. Beyond dietary diversification, interventions to alleviate MNDs, such as food fortification^8,9 and biofortification to increase the micronutrient concentrations in crops^10,11, should account for geographical effects that can be larger in magnitude than intervention outcomes.

Project description:BackgroundThe prevalence of malnutrition in cancer patients ranges from 30 to 60%. While it is known that malnutrition is prevalent among cancer patients, the relationship between undernutrition and quality of life among breast cancer patients has not been adequately explored. Therefore, the present study was aimed at assessing the association between undernutrition and quality of life among Breast Cancer patients under treatment in Addis Ababa, Ethiopia.MethodsA cross-sectional study on breast cancer patients under treatment at the outpatient and in-patient departments of oncology centers of two tertiary hospitals in Addis Ababa - Tikur Anbessa Specialized Hospital (TASH) and St. Paul Millennium Medical College (SPHMMC) oncology was conducted from May 12 to August 26,2020. Nutritional status was assessed using Subjective Global Assessment (SGA) screening tool. Quality of life was assessed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Cancer 30 (EORTC QLQ C30) a standard quality of life measurement scale for cancer patients. To determine the relationship between quality of life scores and nutritional status multivariable linear regression was fitted.ResultsA total of 411 breast cancer patients with mean age of 44.4 (± 11.47) years. And 393 (95.6%) of them female were included in the study. A high prevalence of moderate 127 (30.9%) and severe 106 (25.8%) malnutrition was observed. Moderate (β = -9.21 CI (- 14.59, - 4.67)) and severe (β = -17.81 CI (- 16.6, 2 - 2.91)) malnutrition were negatively associated with the overall quality of life. Malnutrition also showed negative associations with all domains of functional status (P < 0.05) and strong positive associations with symptom scores covered in the EORTC QLQ C-30 (P < 0.05).ConclusionThis study indicated that malnutrition is a major problem among breast cancer patients and the nutritional status breast cancer patients was related to their quality of life….
