Anaemia prevalence and nutrient intake among women in peri-urban settlements in Accra, Ghana

Anaemia among women is a major public health concern globally. In developing countries, nutritional anaemia may be due to poor bioavailability of dietary iron, haemoglobinopathies, or intestinal parasites. The study objectives were to determine the prevalence of anaemia and current nutrient intakes essential to erythropoiesis among women of reproductive age (WRA) in peri-urban settlements in the Ga-East Municipality, Accra, Ghana. This cross-sectional study assessed the nutrient intake, sickling and haemoglobin levels of 134 women aged 15-49 years enrolled in a peanut-based field trial at baseline. A pretested semi-quantitative food frequency questionnaire was used to assess energy and nutrient intake using the Food Processor (ESHA) software. Whole blood was used to determine full blood count using the haematology automated analyser. Sickling was determined by blood staining. Anaemia was classified based on recommended cut-offs. Chi-square analysis was used as a test of independence between anaemia and age groups. Linear regression was used to determine predictors of haemoglobin concentration. The mean age of the women was 29 ± 8 years. The mean total caloric intake was 2315 ± 915 kcal, whilst protein and fat intakes were 67 ± 27g and 68± 30g, respectively. Almost three-quarters of the women met the recommended dietary allowance (RDA) for iron and vitamin C. However, only a third met the RDA for fat, and about two-thirds met their needs for energy and protein. None of the women met the RDA for folate which is integral for haem formation. Also 17% (23/134) of the women were sickle cell anaemia positive. Mean haemoglobin concentration was 12.1 ± 1.8 g/dL. Mild, moderate and severe anaemia due to iron deficiency was present in 35.8%, 6.7% and 1.5%, of the women respectively. All categories of anaemia was present in 44% of the women. Anaemia, prevalence increased during the early stages of the reproductive age (15-29 years) and declined towards the end of the reproductive age period (40-49 years). An increase in age of one year was significantly associated with a 0.056 g/dL rise in haemoglobin level (p=0.014). Anaemia due to iron deficiency exists as a public health problem among women in peri-urban settlements in the Ga-East Municipality, Accra, Ghana. Dietary diversity to include green leafy vegetables which are rich in folate and pro-vitamin A may reduce the current level of prevalence.Key words: Anaemia, Nutrients, Peri-urban, Women, RDA, sickling test, Food Processor softwar

Nutritional status of children 0-59 months in selected intervention communities in northern Ghana from the Africa RISING project in 2012

Background Poor nutritional status during childhood and its long-term impact on economic growth and wellbeing is well known. This study assessed the nutritional status of children in selected communities in northern Ghana, to serve as baseline data for the Africa Research in Sustainable Intensification for the Next Generation (Africa RISING) project that sought to improve farm-household nutrition through agriculture. Methods A cross-sectional study was conducted among children 0–59 months in selected communities in the Northern (Tibali andCheyohi No. 2), Upper West (Goli and Zanko) and Upper East (Bonia and Sambulgu) regions of northern Ghana. A pre-tested, semi-structured questionnaire was used to obtain information on background characteristics of caregivers and children. Weight and height were measured for children following World Health Organization (WHO) procedures and transformed into z-scores using the WHO Anthro. Results All the caregivers (522) were females; majority (73.4 %) had no formal education, 82.7 % were married and 70.5 % engaged in farming. In all, 533 children were recruited: Northern region (38.6 %), Upper West (33.4 %) and Upper East (28.0 %). Majority (52.5 %) of the children were males. The mean age was 32 ± 19 months. Levels of stunting, underweight and wasting were 27.2, 17.6 and 8.2 % respectively. Stunting, underweight and wasting levels increased within the first two years of life. Overall, 33.8 % of the children in northern Ghana were malnourished; 20.2 % were from the Northern region, 7.0 and 6.8 % were from Upper East and Upper West respectively. Conclusion Different forms of malnutrition still exist as a public health problem in various communities in northern Ghana and need to be curtailed using effective agriculture-nutrition sensitive interventions

Comparison of the microbial composition of African fermented foods using amplicon sequencing

Fermented foods play a major role in the diet of people in Africa, where a wide variety of raw materials are fermented. Understanding the microbial populations of these products would help in the design of specific starter cultures to produce standardized and safer foods. In this study, the bacterial diversity of African fermented foods produced from several raw materials (cereals, milk, cassava, honey, palm sap, and locust beans) under different conditions (household, small commercial producers or laboratory) in 8 African countries was analysed by 16S rRNA gene amplicon sequencing during the Workshop “Analysis of the Microbiomes of Naturally Fermented Foods Training Course”. Results show that lactobacilli were less abundant in fermentations performed under laboratory conditions compared to artisanal or commercial fermentations. Excluding the samples produced under laboratory conditions, lactobacilli is one of the dominant groups in all the remaining samples. Genera within the order Lactobacillales dominated dairy, cereal and cassava fermentations. Genera within the order Lactobacillales, and genera Zymomonas and Bacillus were predominant in alcoholic beverages, whereas Bacillus and Lactobacillus were the dominant genera in the locust bean sample. The genus Zymomonas was reported for the first time in dairy, cereal, cassava and locust bean fermentations

DIET MODELLING IN THE DEVELOPMENT OF A HEALTHY DIET FOR THE GHANAIAN POPULATION

Diet modelling is one of the important steps in developing food-based dietary guidelines (FBDGs). However, this component remains uncommon in the FBDGs of many low-and middle-income countries. A diet modelling package (DietSolve) provided by the Food and Agriculture Organization (FAO) was used to formulate a healthy diet based on estimating the daily proportions of food groups that best meet the dietary goals established for the FBDGs for Ghana. Input data for the modelling included a list of commonly eaten foods across the agreed food groups, nutrient and energy content of the foods, current energy and nutrient consumption, and energy and nutrient constraints linked to the dietary goals, as determined by the FBDG multi-Sectoral Technical Task Team (MTTT). The modelling was based on assumptions and constraints including a total daily dietary energy target of 2000 kcal/day; the percentage contribution (energy targets) of the macronutrients as follows: carbohydrates (55-70%), protein (10-20 %), and fat (20-30%) to the total energy target; and calcium (1100 mg/day), iron (20 mg/day), and zinc (11 mg/day) constraints. The situation analysis and evidence review carried out as a prior step guided the diet modelling constraints. Energy contributions were also set for a serving of each food group. The final recommendations were based on food groups with each food group consisting of a variety of commonly consumed foods. The total weight of the optimized diet was estimated at 1514 g/day, including 144g/day of animal-source foods, 41.5g/day of discretionary choices, 226g/day of fruit, 227g/day of vegetables, 6g/day of healthy fats and oil, 198g/day of legumes, nuts, and seeds, and 672g/day of staples. This food group composition will provide an estimated 2639 kcal/day, a deviation of about 32% above the energy target set, made up of ~59% from carbohydrates, ~15% from protein and ~25% from fat, and meeting/exceeding the micronutrient targets set. The Optimised diet is healthier compared to the present dietary patterns of the population; its lower ASF component is known to impact less on the environment
