Variability in vitamin A (VA) intake of pregnant women in Ngaoundere town according to geographic origin, socio-professional and demographic factors was studied. A total of 100 pregnant women attending ante natal visits at the Regional Hospital in Ngaoundere were involved in the survey. A questionnaire was used to obtain information on geographic origin, socio-professional status, birth history, demographic and anthropometric factors. Dietary intake was assessed using 24-hour dietary recall. Meals potentially rich in VA consumed by these women were collected, their carotenoids contents quantified and VA activity determined by conversion. Results indicated that daily VA intake of these women varied significantly (p < 0.05) with geographic origin, level of education and age of pregnancy. VA intake of pregnant women of Northern origin (Adamawa, North and Far North Regions) was significantly (p < 0.05) lower (496 μg/day/woman) than that of women of Southern origin (588 μg/day/woman), although both were below the recommended intake of 800 μg/day/woman. The more educated a woman and the older her pregnancy, the higher her VA intake. VA consumption of pregnant women of Northern origin was significantly influenced by their age, whereas for pregnant women of Southern origin, BMI (Body Mass Index) equally had a significant influence on their VA intake. Socio-professional status, marital status and number of children did not significantly influence the daily VA intake of these women. Thus, a pregnant woman originating from the Northern part of the country and having no formal education, consumed less foods rich in carotenoids and therefore was more at risk for vitamin A deficiency.

This paper examines the risk of Vitamin A deficiency among selected pregnant women in Ngaoundere, Adamawa Region, Cameroon. A total of one hundred (100) pregnant women attending ante natal visits at the Regional Hospital in Ngaoundere were involved in a survey conducted in 2012 which used a 24-hour dietary recall to assess their dietary intake. Food models were used to assist memory and portion sizes of food taken. Carotenoids were quantified in the meals commonly consumed, as well as proteins, sugar, fibers and oil, nutrients intervening in carotenoids absorption and vitamin A metabolism. The results indicated that the dietary intake of vitamin A was inadequate with 37.5% of the selected pregnant women exposed to acute vitamin A deficiency, while 20% of them were exposed to the severe form. The daily consumption of vitamin A was about 539.09 ± 43.09 μg, corresponding to a contribution of 67.39% to the vitamin A requirement of the pregnant women. The dietary intake of macronutrients was also inadequate with a daily consumption of 57.28 ± 12 g for oils, 177.88 ± 29 g for sugars, 47.34 ± 11 g for proteins and 11.28 ± 3 g for fibers corresponding respectively to a contribution of 63.6%, 70.8%, 78.90% and 45.1% of these nutrients requirement in these women. Given that over 50% of the women surveyed were exposed to vitamin A deficiency, there is a need for urgent intervention programs in the area to alleviate this situation.

A Cameroonian Traditional Cake (<i>Komba</i>) Prepared Using Yellow Maize Reduce Vitamin A Deficiency in Lactating Mothers

引用

Vitamin A deficiency (VAD) is a widespread public health problem in developing nations affecting greatly pregnant and lactating women. To alleviate the deficiency, many strategies were set up by the Cameroonian authorities. However, the level of VAD is still very high, thus the option of supplementation of foods remains a very important option. The aim of this study was to evaluate the impact of a food supplementation with komba, a Cameroonian traditional yellow maize cake, on vitamin A status of lactating mothers in Ngaoundere town. To achieve this, 40 lactating mothers were recruited in four health facilities of the Ngaoundere town. They were dewormed and subdivided in two groups of 20 subjects each and fed for two months. The test group received 200 g of yellow maize cake while the control group received 200 g of white maize. 24-hour dietary recall was used to assess their food intake during the study period. Blood sample were collected at the beginning and the end of the study and the serum retinol determined. Results show that before the supplementation, 45% of the women had inadequate level of serum retinol in each group. At the end of the 2 months of supplementation, 30% of the control group remained inadequate, while the totality of all the women in the test group had adequate serum retinol levels (≥1.05 μmol/l). That means an improvement of the vitamin A status in the test group. Results also show a significant (p < 0.05) increase of 36.3% of serum retinol in the test group against 3.8% in the control group. The women of the test group had more chances to see their serum retinol increasing compared to the control group. Consumption of yellow maize cake therefore improves the vitamin A status of lactating mothers. The population can therefore change their habits to consume yellow maize instead of the white maize variety popularly consumed.
