Vitamin D status in Moroccan pregnant women and newborns: reports of 102 cases

Abstract

IntroductionVitamin D insufficiency to pregnant women has been associated with a number of adverse consequences, and has been recognized as a public health concern. The aim of this study was to evaluate vitamin D status of Morrocan pregnant women and their newborns. Our study is being the first of its kind in Morocco, as it supports the program of systematic supplementation of pregnant women in the third quarter. Its results have established a new program for the fight against the deficit of various nutrients, thereby intake of vitamin D has become routine. So this work is a true example of action research.MethodsIt’s an observational and a cross sectional study. The data was collected prospectively from the 1st January to 31 December 2012 in the labor room of the Souissi maternity hospital, at the Ibn Sina university center of Rabat in Morocco. Women included were consented to participate in the study. Data on epidemiological, sociodemographic and clinical characteristics was recolted by interview, physical exam and biochemistry parameters. Hypovitaminosis D is defined as serum level of vitamin D ≤ 50 nmol/l (20 ng/ml).ResultsOur study included 102 cases of mother-newborn pairs. The average age of mothers was 28.3 +/- 6.7 years (range 17-43 years), 90.1% of women enrolled had a hypovitaminosis D, the average weight of newborns was 3377.9 +/- 509g (2270 - 4880g). Hypovitaminosis D is not correlated with the origin, season, body mass index, birth interval and birth weight. It was positively correlated with maternal serum calcium (p=0.000).ConclusionThe maternal hypovitaminosis D is real public health problem. The prevention is necessary, by the systematic vitamin D supplementation for pregnant women.

Maternal and Cord Blood Vitamin D Status and Anthropometric Measurements in Term Newborns at Birth

“…As for data from other countries, Rodriguez et al and Eggemoen et al found no connection between neonatal anthropometric parameters and maternal vitamin D levels, even despite the fact that vitamin D deficiency (<20 ng/ml) was detected in 19.7% and 51% of the women, respectively ( 18 , 35 ). Loudyi et al reported no association between maternal vitamin D status and neonatal weight at birth among the investigated women (vitamin D concentration ≤20 ng/ml in 90% of the cases) ( 36 ). Shakiba and Iranmanesh and Josefson et al found no relationship between cord vitamin D concentration and neonatal weight and length ( 25 , 31 ), while Dalgård et al reported the same lack of relationship for neonatal weight and head circumference ( 37 ).…”

Undernutrition and its associated factors among pregnant mothers in Gondar town, Northwest Ethiopia

“…Maternal nutrition prior to and during pregnancy play a central role in determining the long-term health and nutritional effect of both the mother and her growing fetus [9, 21]. Maternal undernutrition is highly prevalent in low and middle-income countries [7, 9, 10] and Ethiopia as one of these countries has been significantly affected by the burden of undernutrition. We conducted a cross-sectional study to identify the burden and associated factors of undernutrition among pregnant mothers residing in an urban setting.…”

“…Ethiopia is one of the countries with a high burden of maternal and child undernutrition. Though, maternal undernutrition has declined over the past 16 years, from 30% in 2000 to 22% in 2016, Ethiopia is still among countries with a high burden of maternal malnutrition [7]. Specifically, two institution based cross-sectional studies conducted in Amhara region reported a prevalence rate of undernutrition ranging from 16% to 29.8% that also showed a significant geographic variation [3, 8].…”

“…Maternal undernutrition in the low and middle-income countries is an underlining cause for a 3.5 million mother’s deaths and disabilities due to physical and mental effects of poor dietary intake in the earliest months of life [7, 9, 10]. Previous studies have established that undernourished pregnant women suffer from a combination of chronic energy deficiency that leads them to have a low birth weight (LBW), preterm and unsuccessful birth outcomes [11–13].…”

Serum level of 25‐hydroxyvitamin D and obesity among early pregnant women

“…There are few published data on vitamin D status during pregnancy in African countries and there is a high rate (20.0%) of obesity among pregnant Sudanese women . Moreover maternal obesity is associated with maternal and perinatal adverse effects .…”
