AbstractBackgroundDespite perennial sunshine, vitamin D deficiency is prevalent among Malaysian especially pregnant women.ObjectiveTo determine the vitamin D status and its associated factors among third trimester pregnant women attending government health clinics in Selangor and Kuala Lumpur, Malaysia.MethodsInformation on socio-demographic characteristics, obstetrical history, vitamin D intake, supplement use, and sun exposure were obtained through face-to-face interviews. Serum 25-hydroxyvitamin D concentration was measured and classified as deficient (< 30 nmol/L), insufficient (30-50 nmol/L), and sufficient (≥ 50 nmol/L).ResultsOf the 535 pregnant women recruited, 42.6% were vitamin D deficient. They consumed an average of 8.7 ± 6.7 μg of vitamin D daily. A total of 80.4% of the vitamin D were obtained from the food sources, while 19.6% were from dietary supplements. Fish and fish products showed the highest contribution to vitamin D intake (35.8%). The multivariate generalized linear mixed models, with clinic as a random effect, indicates that higher intake of vitamin D is associated with lower risk of vitamin D deficiency among pregnant women (OR = 0.96; 95% CI = 0.93-0.99). Non-Malay pregnant women had lower odds of having vitamin D deficiency (OR = 0.13; 95% CI = 0.04-0.37) compared to Malays. No associations were found between age, educational level, monthly household income, work status, gravidity, parity, pre-pregnancy body mass index, total hours of sun exposure, total percentage of body surface area, and sun exposure index per day with vitamin D deficiency.ConclusionsVitamin D deficiency is prevalent among Malaysian pregnant women. Considering the possible adverse obstetric and fetal outcomes of vitamin D deficiency during pregnancy, antenatal screening of vitamin D levels and nutrition education should be emphasised by taking into consideration ethnic differences.

Vitamin D Levels

Background : Vitamin D is an essential nutrient and deficiency of it leads to devastating disorders. This study aimed to find out the associated factors with selected variables of low vitamin D among adult females of Chattogram. Materials and methods : Cross-sectional observational study was conducted from September 2019 to February 2020 at a diagnostic complex of Chattogram. Participants were adult females of Chattogram. All participants gave oral informed consent and answered a questionnaire that included 16 questions covering demographic information, monthly income, educational status, occupation, body weight, duration of sun exposure, dress pattern (Using hijab or burkha, regular dress-up) drug and disease history. Blood samples were collected by cautious aseptic procedure. Serum vitamin D levels were measured by using immunoassay method. Adult females of Chattogram with no religious restrictions, n= 150,aged 31 to 70 years. Results: Overall, 88% had low vitamin D levels with deficient 60.66% and insufficient 27.34%. Sufficient level of vitamin D was found only among 12%. The prevalence of vitamin D deficiency was much higher in females with house-wife status 73.33% (p value of 0.0001) wearing hijab 46.66% (p value of 0.001). It could be due to interference with UVB radiation into skin, short duration of sun exposure, use of sunblock cream or less supplementary intake. Conclusion : Vitamin D deficiency is an emerging but neglected health issue in modern time, particularly more vulnerable are female population. Ironically, abundant sunlight of Bangladesh seems failed to protect the self-imposed concrete prisoner, classically known as home-makers, and practitioner of indoor life style that leads to avoidance of sun light. However, large sample size is mandatory to boost-up the findings of current study. Chatt Maa Shi Hosp Med Coll J; Vol.20 (2); July 2021; Page 74-78

Vitamin D Levels

Vitamin D deficiency is widely recognised as a major public health issue around the world; and is essential for optimal development and strengthening of the musculoskeletal system including the prevention of conditions such as osteoporosis, osteopenia and rickets. The association between vitamin D and childhood rickets has led to the fortification of food sources and consequently the eradication of the rickets disease. Vitamin D levels are of particular importance for pregnant women, especially for the development of the bone and muscle development of the fetus. In the last decade there has been a substantial increase in the incidence of vitamin D deficiency and the re-emergence of the childhood rickets disease. It is vital that vitamin D levels are at optimal levels during pregnancy as maternal calcium demands increase significantly to meet the demands of the developing fetus, especially in the third trimester.

Aim: Tetraparetic Cerebral Palsy (TCP) patients may present risks factors for Vitamin D deficiency such as increased risk of malnutrition and possibly infrequent sun exposure. The present study aimed to compare the vitamin D status in this population of TCP pediatric patients (Case Group) and compare them with healthy children and adolescents (Control Group). Methods: The clinical data obtained were: gender, age, weight, height, nutritional status, consumption of vitamin D food sources, sun exposure and serum levels of vitamin D. Vitamin D deficiency was defined as 20 ng/mL or less of 25(OH)D; “insufficiency” was defined as between 21-29 ng/mL; “sufficiency” was defined as between 30-100 ng/mL.1 Results: Sixty patients aged 3 to 20 years old were divided into two groups: the Control Group (n=30) and the Case Group (n=30) composed of individuals with TCP. Vitamin D levels did not differ between groups; the mean levels were 26.65 ng/mL (SD: 10.51) in the Case Group and, 28.93 ng/mL (SD: 9.26) in the Control Group. Conclusion: There was no difference identified between vitamin D levels among TCP and control patients, and no relationship between risk factors and serum 25(OH)D levels was observed. Even though Brazil is a tropical country with abundant sunshine during most of the year, there is still a considerable number of individuals with vitamin D classifications of insufficiency and deficiency in our study (N= 34/60). This should be alarming for healthcare professionals who work with the pediatric population, which is a population at risk for the development of disability.

Low maternal vitamin D status during pregnancy may have negative consequences for both mother and child. There are few studies of vitamin D status and its determinants in pregnant women living at northern latitudes. Thus, the present study investigates vitamin D status and its determinants during the third trimester of women living in Sweden (latitudes 57–58°N). A total of ninety-five fair-skinned pregnant women had blood taken between gestational weeks 35 and 37. The study included a 4 d food diary and questionnaires on dietary intake, supplement use, sun exposure, skin type, travels to southern latitudes and measure of BMI. Serum 25-hydroxyvitamin D (25(OH)D) was analysed using the chemiluminescence immunoassay. In the third trimester of pregnancy, mean serum concentration of 25(OH)D was 47·4 (sd18·1) nmol/l (range 10–93 nmol/l). In total, 65 % of women had serum 25(OH)D < 50 nmol/l and 17 % < 30 nmol/l. During the winter, 85 % of the pregnant women had serum 25(OH)D < 50 nmol/l and 28 % < 30 nmol/l. The main determinants of vitamin D status were as follows: season; use of vitamin D supplements; travels to southern latitudes. Together, these explained 51 % of the variation in 25(OH)D. In conclusion, during the winter, the majority of fair-skinned pregnant women had serum 25(OH)D < 50 nmol/l in their third trimester and more than every fourth woman < 30 nmol/l. Higher vitamin D intake may therefore be needed during the winter for fair-skinned pregnant women at northern latitudes to avoid vitamin D deficiency.

AbstractVitamin D deficiency during pregnancy is associated with negative health consequences for mothers and their infants. Data on the vitamin D status of pregnant women in Switzerland are scarce. A three-centre study was conducted in the obstetric departments of Zurich, Bellinzona and Samedan (Switzerland) to investigate the prevalence and determinants of vitamin D deficiency (serum 25-hydroxyvitamin D (25(OH)D)<50 nmol/l) in 3rd-trimester pregnant women living in Switzerland (n 305), and the correlation between 25(OH)D in pregnant women and their offspring at birth (n 278). Demographic and questionnaire data were used to explore the determinants of vitamin D deficiency. Median concentration of serum 25(OH)D in the third trimester of pregnancy was 46·0 nmol/l (1st–3rd quartiles: 30·5–68·5), representing a 53·4 % prevalence of vitamin D deficiency. 25(OH)D levels in the umbilcal cord blood (median: 50·0 nmol/l; 1st–3rd quartiles: 31·0–76·6) strongly correlated with mothers’ serum 25(OH)D (Spearman’s correlation ρ=0·79, P<0·001). Multivariable logistic regression analysis showed that significant determinants of vitamin D deficiency in pregnant women were centre of study, country of origin, season of delivery and vitamin D supplement intake. Near-term BMI, skin colour, use of sunscreen and mothers’ education, although each not individually significant, collectively improved the ability of the model to explain vitamin D status. Low vitamin D levels were common in this sample of pregnant women and their newborns’ cord blood. Vitamin D supplement intake was the most actionable determinant of vitamin D status, suggesting that vitamin D supplementation during pregnancy should receive more attention in clinical practice.

Background: In the recent years there has been an increased understanding of the role that vitamin D plays in regulation of cell growth, calcium absorption and immunity and its impact on the developing fetus and maternal health is of significant concern. This study aims at evaluating the Vitamin D status in pregnant women and their newborns.Methods: A cross sectional study was done on 100 pregnant females according to inclusion and exclusion criteria. At the time of delivery, maternal blood was collected, and newborn samples were taken from newborn side of umbilical cord and sent for analysis.Results: The prevalence of Vitamin D deficiency has been found to be 85% of pregnant females and 91% of the newborns. Only 5% of pregnant females and 1% of the newborns showed Vitamin D sufficiency. Maternal and newborn vitamin D levels show a positive correlation. Mean maternal and newborn Vitamin D levels were found to be 16.78±7.04 ng/mL and 11.29±5.75 ng/ml.Conclusions: Vitamin D deficiency is highly prevalent among pregnant women in north India. Low maternal vitamin D levels lead to vitamin D deficiency in the newborns also.

ABSTRACT Background Evidence is lacking to determine whether there have been any changes in dietary or total usual intakes of vitamin D among Canadians, in the light of recent evidence of beneficial health effects beyond bone. Objective We aimed to examine trends in dietary and total usual intake of vitamin D among Canadians aged ≥1 y. Methods This study used nationally representative nutrition data from the Canadian Community Health Survey Cycle 2.2 (CCHS 2004) and CCHS Nutrition in 2015. Dietary intake data were collected with use of two 24-h dietary recalls and dietary supplement use was determined by questionnaire. The National Cancer Institute method was used to estimate the usual intake of vitamin D as well as the prevalence of vitamin D inadequacy among Canadians aged ≥1 y. Results From 2004 to 2015, the usual intake of vitamin D from food significantly decreased (P &lt; 0.05) by 1 μg/d only in vitamin D supplement nonusers. The contribution of Milk and Alternatives food group (i.e., fluid milk, fortified soy beverages, powdered milk, and other milk alternatives) to dietary vitamin D intake significantly decreased (P &lt; 0.05) in both supplement users (by 7.1%) and nonusers (by 5.8%). Prevalence of vitamin D supplement use and percentage contribution of vitamin D from supplemental sources significantly increased (P &lt; 0.05) by 5.0% and 14.9%, respectively, from 2004 to 2015. Total usual intake of vitamin D (food + supplement) significantly increased (P &lt; 0.05) from 15.1 ± 0.3 μg/d in 2004 to 31.5 ± 1.8 μg/d in 2015 in vitamin D supplement users. In contrast to vitamin D supplement nonusers, the prevalence of vitamin D inadequacy significantly decreased (P &lt; 0.05) from 20.6% to 14.1% among users of vitamin D supplements. Conclusions The prevalence of vitamin D supplement use and the percentage contribution of vitamin D from supplemental sources has increased in the Canadian population over an 11-y period.

Background. Vitamin D, a fat-soluble vitamin, has various extraskeletal effects, and several human and animal studies have suggested that vitamin D deficiency may be a contributory factor in the pathogenesis of coronary artery disease (CAD). However, such studies in the Indian subcontinent are either lacking or have shown conflicting results. Methods. This was a descriptive cross-sectional study involving 121 patients with CAD from a tertiary care center and their 80 age-matched healthy controls. Serum vitamin D levels along with serum and urine chemistries were measured in both the groups. The average duration of sun exposure/day and use of sunscreen were also considered in the study cohort using a questionnaire. Serum vitamin D levels were categorized into deficient (<30 nmol/lit), insufficient (30–75 nmol/lit), and sufficient (>75 nmol/lit) groups. Results. Among the cases, 51.2% of the patients were vitamin D deficient and 44.6% patients had insufficient vitamin D levels, whereas among controls, 40% and 31% of the population had deficient and insufficient levels of vitamin D, respectively. However, the mean value of the serum vitamin D level was not statistically different in the cases as compared to that of the controls (34.06 vs 40.19 nmol/lit) (P=0.08). Corrected serum calcium (9.26 vs 9.59 mg%) (P≤0.0001) and serum albumin levels (4.21 vs 4.75 gm%) (P≤0.0001) were lower in the cases than those of the controls. The average sun exposure/day was higher among the cases than that among the controls (2.93 vs 1.85 hours) (P=0.001). Conclusion. Vitamin D deficiency is widely prevalent in Indian population despite abundant sunshine, and the duration of sun exposure is not correlated with serum vitamin D levels. Vitamin D deficiency is not associated with CAD. However, serum calcium is deficient in CAD patients as compared to the controls. Large-scale studies are required to explore the association further to evaluate the benefits of screening and correction of vitamin D deficiency in patients with CAD.

The study objective was to validate a food frequency and lifestyle questionnaire (FFLQ) to assess vitamin D intake and lifestyle factors affecting status. Methods: Data collected previously during the fall (n = 86), winter (n = 49), and spring (n = 67) in collegiate-athletes (Study 1) and in active adults (n = 123) (Study 2) were utilized. Study 1: Vitamin D intake and ultraviolet B exposure were estimated using the FFLQ and compared to serum 25(OH)D concentrations via simple correlation and linear regression modeling. Study 2: Vitamin D intake from food was estimated using FFLQ and compared to vitamin D intake reported in 7-Day food diaries via paired t-test and Bland–Altman analysis. Results: Study 1: Serum 25(OH)D was not associated with vitamin D intake from food, food plus supplements, or sun exposure, but was associated with tanning bed use (r = 0.39) in spring, supplement use in fall (r = 0.28), and BMI (body mass index) (r = −0.32 to −0.47) across all seasons. Serum 25(OH)D concentrations were explained by BMI, tanning bed use, and sun exposure in fall, (R = 0.42), BMI in winter (R = 0.32), and BMI and tanning bed use in spring (R = 0.52). Study 2: Estimated Vitamin D intake from food was 186.4 ± 125.7 via FFLQ and 148.5 ± 228.2 IU/day via food diary. There was no association between intake estimated by the two methodologies (r = 0.12, p < 0.05). Conclusions: FFLQ-estimated vitamin D intake was not associated with serum 25(OH)D concentration or food-record-estimated vitamin D intake. Results highlight the difficulty of designing/utilizing intake methodologies for vitamin D, as its status is influenced by body size and both endogenous and exogenous (dietary) sources.
