ABSTRACT Background Vitamin A deficiency is a public health problem in sub-Saharan Africa. Pro-vitamin A biofortified (yellow) cassava has the potential to contribute significantly to improve vitamin A status, especially in populations that are difficult to reach with other strategies. Objectives The study aimed at determining the efficacy of biofortified cassava to improve vitamin A status of Nigerian preschool children. Methods An open-label randomized controlled trial was conducted in southwestern Nigeria. In total, 176 preschool children (aged 3–5 y) were randomized into 2 parallel arms comprising an experimental group (n = 88), fed foods prepared from biofortified (yellow) cassava, and a control group (n = 88), fed foods prepared from white cassava, twice a day, 6 d a week for 93 d. Results A total of 159 children completed the trial (yellow cassava group, n = 80; white cassava group, n = 79). Children consumed 221 and 74 µg/d retinol activity equivalents from intervention foods in the yellow and white cassava groups, respectively. The treatment effect on serum retinol concentrations at the end of the feeding trial was 0.06 µmol/L (95% CI: 0.004, 0.124 µmol/L), after adjustment for baseline retinol concentrations, inflammation, and asymptomatic malaria status. No significant treatment effects were detected for serum β-carotene (adjusted effect: 3.9%; 95% CI: −0.6%, 8.6%) and gut permeability (adjusted effect: 0.002; 95% CI: −0.089, 0.092), but a significant effect was detected for hemoglobin concentrations (adjusted effect: 3.08 g/L; 95% CI: 0.38, 5.78 g/L). Conclusions Daily consumption of β-carotene from biofortified cassava improved serum retinol and hemoglobin concentrations modestly in Nigerian preschool children. This study was registered with clinicaltrials.gov as NCT02627222.

AbstractAims:To investigate the prevalence of vitamin A deficiency among lactating women in a poor urban population of Bangladesh, and to examine the relationship between various factors and vitamin A status.Design:Cross-sectional study.Setting:Maternal and child health clinic in Dhaka City, Bangladesh.Subjects and methods:A total of 120 lactating women aged 17–37 years were randomly selected from women who attended a local maternal and child health clinic in Dhaka City for immunisation of their children. Various socio-economic, personal characteristics, dietary intakes of vitamin A and anthropometric data were collected. Serum retinol (vitamin A) concentration was determined as a measure of vitamin A status.Results:Of the subjects, 37% had low serum vitamin A levels (<30 μg dl−1), with 13.3% having sub-clinical vitamin A deficiency (<20 μg dl−1). Eighty-seven per cent had vitamin A intakes below the recommended dietary allowance. The lactating women who were either illiterate or received only informal education had significantly (P = 0.002) lower serum vitamin A levels compared with those who received formal education. The women whose husbands received formal education had significantly (P = 0.05) higher serum vitamin A levels than those whose husbands were either illiterate or received only informal education. The serum vitamin A levels of women in households with poor sanitation/latrine practice were significantly (P = 0.03) lower than those of women in households with good sanitation/latrine practice. The women with one child had significantly (P = 0.015) lower serum vitamin A levels than those with two or more children. Women with a lactation period of 6 months or more had significantly (P = 0.034) lower serum vitamin A levels than women with a lactation period of less than 6 months. The women who consumed less than the median vitamin A intake (274.8 μg day−1) had significantly (P = 0.01) lower serum vitamin A levels than those who consumed more than the median vitamin A intake. By multiple regression analysis, education level of the women, number of living children, duration of lactation and dietary intake of vitamin A were found to have significant independent relationships with serum vitamin A. The overall F-ratio (6.8) was highly significant (P = 0.000), the adjusted R2 was 0.16 (multiple R = 0.44).Conclusion:A significant proportion of poor, urban, lactating women in Bangladesh have vitamin A deficiency. Among the various factors, education level of the women, number of living children, duration of lactation and dietary intake of vitamin A appear to be important in influencing the vitamin A status of these women.

Background: Beside calorie and protein consumption micronutrients like folic acid, vitamin D and vitamin A have been postulated to play major role in intrauterine growth of neonates. Vitamin A compounds are critical for vision, reproduction, embryonic development, immune function and regulation of cell proliferation and differentiation.Aims and Objectives: To determine the relationship of maternal serum vitamin A levels with birth weight of babies.Material and Methods: Study group consisted of 58 randomly selected mothers who delivered at term small for gestational age babies (birth weight less than 2.5kg.). The control group comprises of 52 matched mothers, who delivered normal babies. Biochemical estimation of serum vitamin A was done by HPLC method using sigma reagent of all subjects.Results: Significantly high (p<0.05) number of mothers in study group had low serum vitamin A level compared to mothers in control group. There was a linear relationship between vitamin A status and mean birth weight of the babies.Conclusion: Although the low serum vitamin A level of mothers was significantly associated with intrauterine growth retardation, the exact effect of a vitamin A deficiency on the birth weight of babies remain unclear, but the finding suggests the importance of adequate vitamin A supplementation to pregnant mothers in India.Asian Journal of Medical Sciences Vol.8(3) 2017 30-34
