“…Despite sufficient sun exposure in 57% of women, all participants had hypovitaminosis D < 30 ng/mL, with a median of 8.42 ng/mL. Baki et al [ 36 ] and the national nutrition survey (ENN 2019) [ 37 ] confirms the high prevalence of hypovitaminosis D in women of childbearing age in Morocco. Nevertheless, the findings indicated a significant increase in 25-OHD levels as sun exposure progressed from insufficient to sufficient (4.78 and 10.47, respectively; p < 0.0001).…”

“…The sample size (n0) was set concerning Cochran’s formula [ 79 ]: n 0 = z 2 pq/e 2 ; where z is the value from the standard normal distribution reflecting the confidence level (Z = 1.96 for 95%); p is the estimated prevalence of hypovitaminosis D in Moroccan women of reproductive age (limited to studies defining hypovitaminosis D as a circulating level of 25(OH)D less than 30 ng/mL); p is calculated based on the mean prevalence of hypovitaminosis D in premenopausal and reproductive age women reported by Allali et al [ 33 ] and Baki et al [ 36 ], respectively, ( p = 90%); q is 1 − p, and e is the desired level of precision set at 5%. Thus, 138 women were required to obtain statistically representative data.…”

“…In Morocco, vitamin D deficiency is widespread, with a prevalence of 76.6 to more than 90%, especially in women over 50 years of age [ 33 , 34 , 35 ], and is becoming increasingly common among women of reproductive age. A study in Marrakech showed that 100% of participants aged 18–45 years had hypovitaminosis D (<30 ng/mL) [ 36 ]. Similarly, a recent national nutrition survey (NNS 2019) published in 2022 found that 78% of women of childbearing age have 25(OH)D levels below 20 ng/mL [ 37 ].…”

Sunlight exposure is an essential source of vitamin D for many humans. However, hypovitaminosis D is a global public health problem. This study aimed to develop and validate a sun exposure score (SES) and correlate it with serum 25-hydroxyvitamin D levels in women of childbearing age. One hundred and sixty women aged 18 to 45 years residing in Meknes, Morocco, were included. A questionnaire estimating the sun exposure score and blood analysis of serum 25-OHD concentration were performed. The questionnaire’s reliability and construct validity were evaluated using Cronbach’s alpha and factor analysis. Spearman’s test was used to assess the correlation between SES and 25-OHD levels. The score’s reliability and construct validity were good, with Cronbach’s alpha values >0.70 and factorial saturation ranging from 0.696 to 0.948. Serum 25-OHD levels were significantly associated with the total sun exposure score, and all SES domains (Rho was 0.615 (p < 0.0001), 0.307 (p < 0.0001), 0.605 (p < 0.0001), and 0.424 (p < 0.0001) for total SES, indoor exposure domain, outdoor exposure domain, and sun protection practice domain, respectively). In addition, median 25-OHD levels increased significantly when sun exposure was changed from insufficient to sufficient (p < 0.0001). The results suggest that the sun exposure score could be used as a clinical tool to assess vitamin D levels in women of childbearing age.

“…En effet, plusieurs études, dans des régions fortement ensoleillées, présentent la même tendance que la nôtre et rapportent une prévalence très importante de la carence en Vit.D. C'est le cas des pays voisins, ayant les mêmes conditions climatiques que l'Algérie, comme le Maroc, où une étude transversale réalisée chez 96 patientes jeunes, âgées entre 18 et 45 ans dans de la ville de Marrakech, a révélé une prévalence de l'hypovitaminose D de 100%, avec une valeur moyenne de 10,30±8,5 nmol/L [15]. Au Maroc, toujours, et dans une étude plus récente réalisée par Skalli et al, sur 146 sujets adultes en bonne santé, la prévalence de la carence en Vit.D était de 84,25% [16].…”

Introduction. Without magnesium, vitamin D cannot be converted to its biolo- gically active form, a relationship that is often overlooked. Objective. The aim of this study was to estimate the frequency of hypovitaminosis D and that of hypomagnese-mia on the one hand, and to analyze the relationship between vitamin D status, magnesium, and plasma parathormone on the other hand. Population and methods. A retrospective descriptive-analytical,and epidemiological study was conducted on a 112 apparently healthy young adult subjects. For this purpose, bioassays of 25-hydroxy-vitamin D, magnesium and plasma parathormone were performed. Results. The frequency of hypovitaminosis D (serum 25-hydroxyvitamin D  30ng/mL) represented 88.39%. Hypomagnesemia affeted 43.75% of the studied population. A highly significant positive correlation was noted between plasma magnesium levels and vitamin D status of the subjects (R= 0.849; P = 0.000), whereas, a very significant negative correlation was observed between magnesium and plasma parathormone levels (R=-0.92 ; P = 0.000). Conclusion. A high frequency of hypovitamin D, a significant frequency of hypomagne-semia, and a positive correlation between plasma magnesium and vitamin D status are observed. Magnesium level is a determining factor in the variation of serum calcidiol concentrations that should be considered in the assessment of vitamin D status.

Background: Hypovitaminosis D is a global public health problem. In Algeria, little work is done on the epidemiology of vitamin D deficiency targeting all at-risk populations. Objectives: The main objective of this study is to estimate the prevalence of hypovitaminosis D in healthy young adults. The secondary objectives are to identify the determinants of vitamin D status and to analyze the correlations between plasma calcidiol levels and other parameters of phosphocalcic metabolism. Material and methods: Cross-sectional descriptive, prospective and multicentric epidemiological survey of 945 subjects belonging to the Region of Blida (Algeria), assessment of 25-hydroxy-vitamin D, calcium, phosphorus, parathormone, alkaline phosphatase and albumin for each subject. The study also included a questionnaire to identify the determinants of vitamin D status in this population. Results: There is a high prevalence of hypovitaminosis D (calcidiol < 30 ng/ml), with 92.6% of subjects affected, of whom 27.5% had an insufficiency (calcidiol 20 -29 ng/ ml), however 65.1% of subjects were deficient (calcidiol < 20 ng/ml). No significant correlation was detected between 25-hydroxy-vitamin D and plasma calcium (R=0.051; P=0.115), a significant positive correlation was found between 25-hydroxy-vitamin D and phosphorus (R=0.146; P< 0,05). A negative correlation was detected between calcidiol and parathormone (R= -0.886; P< 0,05) and between calcidiol and alkaline phosphatase (R= -0.828; P< 0,05). Based on multivariate analysis, the 3 top risk factors that were associated with hypovitaminosis D are sun exposure time <30 min (adjusted OR =202.11, [95% CI]: 48.91; 835.10; P< 0,05), lack of knowledge about vitamin D (adjusted OR =46.45; [95% CI]: 20.84 ;103.52; P< 0,05), and dark phototype (adjusted OR =39.67; [95% CI]: 14.31; 109.99; P< 0,05). Conclusions: Hypovitaminosis D can be considered a public health problem in Algeria affecting young healthy populations. It is necessary to develop multisectorial programs in order to better address risk factors, particularly modifiable ones, and develop a strategy for prevention and care.
