Objective: To study the Prevalence of Vitamin D deficiency in pregnant women. Study Design: A Cross-sectional analyticalstudy through convenient sampling technique. Setting and duration: At a private Clinic located at East Canal Road Faisalabad, from March2011 to June 2011. Material and method: The study included consecutive 61 pregnant women of reproductive age and non-pregnant womenwere excluded. Blood samples were taken in morning i.e. overnight fasting samples, by venepuncture by disposable syringes sample weretaken and samples were stored at -20 degree centigrade till they were analyzed. Our interest was in age and serum Vitamin D 3 levels. Results:Out of 61 pregnant women results showed that 87.0% pregnant women were having Vitamin D deficiency, 10.0% were having Vitamin Dinsufficiency, 3.0% had Vitamin D sufficiency and none shows Vitamin D intoxication. Vitamin D deficiency was more prevalent in pregnantwomen of younger age group. Furthermore prevalence was higher among the pregnant mothers with high parity. Moreover, 65% women werenot exposed to sunlight properly, 60% women had muscle cramps and bony aches. 90% women never were tested for tested Vitamin D levelsbefore. Conclusions: Prevalence of Vitamin D deficiency is significant in pregnant women. It is also important for its effects on various organsand systems of body as well as on pregnancy and neonate. The different aspects of study led to conclusion to emphasize that Health educationbe imparted to pregnant women and their families in terms of diet, proper sunlight exposure and taking Vitamin D supplements in pregnancy. It isthus recommended to perform Vitamin D levels in every pregnant woman.

Abstract. We aim to assess the prevalence of vitamin D deficiency (VDD) in patients scheduled for bariatric surgery (BS), and to identify factors that might be associated with VDD. We conducted a cross-sectional observational study involving all consecutive patients scheduled for BS from 2017 to 2019. The exclusion criteria were missing data for vitamin D levels, intake of vitamin D supplements in the 3 months prior to serum vitamin D determination, and renal insufficiency. A total of 206 patients (mean age and body mass index [BMI] of 34.9 ± 10.7 years, and 44.3 ± 6.99 kg/m2, respectively) met the inclusion criteria and were enrolled for data analysis. VDD (<19.9 ng/mL), severe VDD (<10 ng/mL), and vitamin D insufficiency (20–29.9 ng/mL) were present in 68.8 %, 12.5 %, and 31.2 % of patients, respectively. A significant inverse correlation was found between vitamin D levels and initial BMI, parathyroid hormone, and homeostatic model assessment of insulin resistance (r = −0.280, p < 0.05; r = −0.407, p = 0.038; r = −0.445, p = 0.005), respectively. VDD was significantly more prevalent in patients with higher BMI [−0.413 ± 0.12, CI95 % (−0.659; −0.167), p = 0.006], whereas no significant association between hypertension [−1.005 ± 1.65, CI95 % (−4.338; 2.326), p = 0.001], and diabetes type 2 (T2D) [−0.44 ± 2.20, CI95 % (−4.876; 3.986), p = 0.841] was found. We observed significant association between female sex and levels of vitamin D [6.69 ± 2.31, CI95 % (2.06; 11.33), p = 0.006]. The present study shows that in patients scheduled for BS, VDD deficiency is common and was associated with higher BMI, and female sex.

Background: Recently, we see in our clinical practice that many patients who are coming with generalized body aches and pains and diagnosed as fibromyalgia or chronic fatigue, not adequately responding to treatment. When their vitamin D level was done, it was found to be low and correction of their low vitamin D level improved their symptoms dramatically. Despite abundant sunshine in Bangladesh, allowing vitamin D synthesis all the year round, why our people are developing hypovitaminosis D inspired us to do this current study. Our present study is designed to estimate the prevalence of vitamin D deficiency among adult patients presented with aches & pains as well as to study the association of low vitamin D levels with different socio-demographic parameters.Methods: A cross sectional observational study was conducted among 212 adult patients aged 18 years and above presented with generalized body aches and pains, attended both outpatient and inpatient departments of Popular Medical College Hospital during the period of March’16- August’16 ( 6 months). Association between vitamin D status & the individual specific variables was statistically analyzed.Results: The prevalence of vitamin D deficiency among the study population was found to be100% in all age groups. Among 212 study population, 73.6% were female (n=156) & 26.4% were male (n=56). Mean Vitamin D level among male was 14.29 (SD 4.68) & among female was 12.64 (SD 4.74). The factors associated with severely deficient Vitamin D level were female sex, urban population, &obesity. It is alarming that 64.2% of our study population were totally unaware about the importance of sun exposure.Conclusions: Vitamin D status was associated with a number of socio-demographic variables. Knowledge of these variables may improve targeted education and public health initiatives.J MEDICINE Jan 2018; 19 (1) : 22-29

Abstract Background: This study was thus undertaken to study the estimation of vitamin D levels in pregnant women and their newborns in DRC and to study its association with various neonatal outcomes. Methods: Observational study done on 569 pregnant women and their newborn babies. Sample obtained from maternal serum and cord blood from the placental end during peripartum period. The data was analysed to estimate the prevalence of vitamin D levels in mothers and newborns and to identify association, if any, between maternal vitamin D levels and neonatal outcomes.Results: 464 mothers had sufficient vitamin D (VDS) levels (>30 ng/dL) and 105 had vitamin D deficiency (VDD) with mean maternal serum vitamin D level of 35.63ng/ml (SD 6.18, range 9.2-39.8). All the newborns (n=569) were vitamin D deficient (<30ng/ml). The percentage of LBW babies born to VDD mothers was 18.09%, which was very similar to the percentage of LBW babies born to VDS mothers (18.31%) (p=0.76456749). The incidence of caesarean section was 58.09% in the vitamin D deficient (VDD) group as compared to 19.61% in the sufficient (VDS) group (p<0.0005). The incidence of preterm births was 10.77% in the sufficient group (VDS) as compared to 17.14% in the vitamin D deficient (VDD) group (p=0.038). Conclusion: Our findings will help health professionals, policy makers, and the general public in Africa aware of the high prevalence of vitamin D deficiency and the associated health risks.

This cross-sectional study enrolled 180 patients at a private family practice in Virginia. Total serum vitamin D concentrations were obtained weekly from January 30, 2013, through March 30, 2013, in consecutive patients regularly scheduled for laboratory work at the practice. Patients were categorized into 2 groups and analyzed for variant alleles in vitamin D receptor ( VDR; rs2228570), cytochrome P450 2R1 ( CYP2R1; rs10741657), 7-dehydrocholesterol reductase ( DHCR7; rs12785878), and group-specific component ( GC; rs2282679) to determine whether variants of those alleles influenced total serum 25(OH)D concentrations. One-hundred and eighty patients were enrolled, with 40 (22%) being sufficient, 25-hydroxy vitamin D level 25(OH)D ≥ 30 ng/mL, and 140 (78%) being insufficient, 25(OH)D < 30 ng/mL. Of the 4 genes, 2 genes, CYP2R1 (rs10741657) and GC (rs2282679), demonstrated a significant association related to vitamin D status. Subjects with 1 or more variant alleles at rs10741657 were almost 3.7 (odds ratio [OR] 3.67; 95% confidence interval [CI]: 1.35-9.99) times more likely be insufficient in vitamin D and subjects with 1 or more variant alleles at rs2282679 were about half (OR 0.42; 95% CI: 0.18-0.93) as likely to be insufficient in vitamin D. Allelic variations in CYP2R1 (rs10741657) and GC (rs2282679) affect vitamin D levels, but variant alleles on VDR (rs2228570) and DHCR7 (rs12785878) were not correlated with vitamin D deficiency, 25(OH)D < 30 ng/mL.

Abstract Background Vitamin D deficiency is common among post-menopausal women and it is important to treat vitamin D deficiency to prevent falls and fractures in patients with osteoporosis. Few studies examined the prevalence of vitamin D deficiency in general population of Sri Lanka but no studies to date done among post-menopausal women with osteoporosis. This is the first study of such kind conducted to evaluate the serum vitamin D levels and factors related to Vitamin D deficiency among postmenopausal women.Methodology Hospital based Cross -sectional study was conducted at the Endocrine Unit, Teaching Hospital from January to December 2018.During the study period 105 postmenopausal women registered for DEXA scan with Endocrine Unit were recruited to the study. Data collection was done by investigators and blood sample was taken from each participant by registered nursing officers and sample was analysed by using immunohistochemistry assays. Serum Vitamin D levels were categorized and data analysis was done using SPSS 26.Results Mean age of 105 postmenopausal women was 67.7 with minimum 33 and maximum 84 years. Mean Vitamin D levels were 27.5(range11.7-52.5ng/ml). Vitamin D levels were adequate in only 36.2% (95%CI: 27.4-45.7) of women, 44% had insufficient levels and deficiency was present in 19% (95%CI: 12.4-27.4) of participants. Among the 105 women 20% were vegetarian and 53% of them consuming milk on average 3 days per week, 76.2% consuming fish on average 2 days per week, 64.8% consuming egg on average 1 day per week. Furthermore seventy five participants (71.4%) reported adequate level of sun exposure (>30minutes).Commonly reported vitamin deficiency symptoms includes paraesthesia (57.1%),bone pain (55.2%), easy fatigability (54.3%), malaise (51.4%), muscle cramps (43.8%) and proximal myopathy (40.0%).Among 71(66.7%) completed bone density assessment,38% (27.3-49.7) of them showed osteoporosis range. Vertebral Z score showed a significant correlation with vitamin D level(r-0.252, P-0.034).Conclusion Prevalence of vitamin D deficiency is relatively high among the post-menopausal women with a provisional diagnosis of osteoporosis. It is essential to correct vitamin D deficiency with supplementation when initiating treatment for osteoporosis. So vitamin D testing is desirable in decision making to treat or not to treat.

Aim: Vitamin D deficiency is an important public health problem, especially affecting children. The aim of our study is to evaluate the serum 25 (OH) vitamin D levels of children during the summer and to determine some features such as exposure to the sun, oral vitamin D supplementation, and to examine the parameters that affect serum vitamin D levels. Methods: In our study, children aged between 12 and 83 months were included. A questionnaire was answered by families. In this cross-sectional study, serum 25 (OH) vitamin D levels of children and biochemical parameters were examined. Results: The mean serum 25 (OH) vitamin D level was 27.0±12.4 ng/ml. Vitamin D deficiency was found 17%, and vitamin D insufficiency was 6%. The children that taking daycare indoors and body mass index <5th percentile had lower serum 25 (OH) vitamin D levels. Children between the ages of 12- 36 months and children with chronic diseases were found to have a shorter time to benefit from sunlight. Conclusion: The rate of vitamin D deficiency and insufficiency (<20 ng/ml) in children were found at 23% in summer season. Families and caregivers should be informed about vitamin D and should be aware of safe sun exposure. Keywords: Vitamin D, sunlight, summer, children, vitamin D deficiency

Background: Various factors lead to hypovitaminosis (decreased vitamin D levels in serum/blood), in general population, sunlight being one of the major factors. Doctors and staff nurses are particularly at risk due to long working hours indoors, which deprives them of adequate Ultraviolet light exposure.Methods: It was a prospective descriptive cross sectional study conducted at Ziauddin University Hospital, Keamari campus, from August 2018 to July 2019. The objective of this study was to determine the status of vitamin D deficiency among doctors and staff nurses working at Ziauddin University Hospital. All those doctors and staff nurses were included in the study, who were already advised by physicians to get serum vitamin D levels done for their symptoms. Results: A total sample of 118 was collected. 56 doctors and 62 staff nurses participated in the survey. 85 out of 118 (72%) subjects were either deficient or insufficient of vitamin D. Conclusion: Even though doctors and nurses are considered to have better understanding of vitamin D deficiency symptoms and morbidity it causes; still this study found out that majority of the healthcare providers working at Ziauddin hospital were deficient of this vitamin.

Background: Maternal and fetal vitamin D deficiency has nowadays emerged as a frequent morbidity. Adequate vitamin D concentrations during pregnancy are necessary to maintain neonatal calcium homeostasis, bone maturation and mineralization. Objectives of this study were to evaluate serum vitamin D concentration in mothers and its correlation with neonatal cord blood vitamin D at the time of delivery and to study the impact of hypovitaminosis on neonatal anthropometry. Effect of related factors like calcium (Ca), alkaline phosphatase (ALP) and parathyroid hormone (PTH) on maternal vitamin D levels were to be evaluated.Methods: Cross sectional study was done on a total of 220 healthy uncomplicated antenatal females with singleton pregnancy attending labor room at the time of delivery. Maternal and neonatal cord blood samples were drawn in the delivery room and analyzed. Neonatal anthropometry was recorded. Correlations among various maternal and neonatal factors were studied.Results: Widespread vitamin D deficiency was observed in expectant subjects and neonates with 70.91% having deficient levels which were also reflected in newborns (71.82%). Maternal ALP (r= -0.5503, p=0.000) bears a weak negative correlation (p<0.05), maternal serum Ca positive correlation (r = 0.7486, p=0.000) and plasma PTH levels a negative correlation (r = -2.084, p=0.000) with hypovitaminosis. No significant correlation was observed between neonatal anthropometry and vitamin D levels.Conclusions: High prevalence of hypovitaminosis was observed among pregnant women and their neonates in this study. A positive linear relationship was seen between maternal and cord blood vitamin D (r 0.974, p 0.0001).

Vitamin D deficiency is prevalent across all age groups in epidemic proportions. The purpose of this study was to acquire a baseline assessment and create awareness among medical students regarding vitamin D. A cross-sectional, voluntary survey was conducted among undergraduate medical students. Data were collected using a questionnaire which assessed the level of knowledge students had with regard to where vitamin D comes from, what it does for health, how much is recommended, factors that affect its levels, and deficiency management. Majority of students were unaware that vitamin D deficiency has attained epidemic proportions. Though bone and skeletal disorders as a complication of vitamin D deficiency were known, a large number were unaware of systemic consequences (diabetes mellitus, cardiovascular diseases, and cancers). Only one-third of respondents were aware of duration and timing of sun exposure required for adequate serum vitamin D levels. However, we observed lack of awareness among students regarding the various biochemical forms, dose, and duration of vitamin D supplementation for treatment of nutritional deficiency. Our study highlighted a lack of knowledge about the importance of vitamin D, worldwide prevalence of vitamin D deficiency, and its management among medical students. Promoting vitamin D health awareness, if replicated across populations, could lead to positive health outcomes globally.

Abstract An analysis of the structure of the causes of infertility shows that up to almost 25% of women of reproductive age ovulation disorders are observed. Hormonal disorders leading to the absence of ovulation, began to play a leading role in the etiology of infertility, special vitamin D deficiency, while today it has been established that its D receptors (VDR) are localized in most organs, including reproductive ones. VDR affect the expression of 1000 genes and play a crucial role in the implementation of sex hormones function. The aim of the study was to assess the vitamin D level in women of reproductive age, depending on the presence of signs of PCOS and waist circumference (WC). 71 women from 19 to 44 years old were examined of these, 41 patients were diagnosed with PCOS and impaired ovulatory function, in 30 patients the ovulatory cycle was preserved, and signs of PCOS were not detected. The level of vitamin 25 (OH) D3 in the serum of the subjects was evaluated by tandem chromato-mass spectrometry at the ArchiMed clinic of new medical technologies, Moscow. In the recommendations of the Canadian “The Vitamin D society”, 40-60 ng/ml the optimal level of serum vitamin D, a concentration of 20-40 ng/ml insufficiency, &lt;20 ng/ml as a deficiency. Vitamin D deficiency was detected in 57% of women in both groups, with a pronounced deficiency (&lt;10 ng/ml) in 17%, insufficiency was observed in 43% of cases, a sufficient level was not detected in any of the subjects. The average level of vitamin D in patients with PCOS was 18.2 (2 to 32.3) ng/ml, the value in patients without signs of PCOS was 18.5 (6.8 to 31) ng/ml. Comparison of the vitamin D value with WC showed that in women with PCOS with an WC &lt;80 cm the value of this indicator was 18.8 ng/ml, and for WC ≥ 80 cm it was statistically significantly lower - 13.3 ng/ml (p&lt;0.05). Conclusion. High prevalence of vitamin D deficiency among patients of reproductive age, with no differences in the magnitude of this indicator depending on the presence of signs of PCOS and persistent ovulation. Difference was established between the levels of vitamin D in patients with PCOS depending on the waist circumference - its insufficiency increases with an increase in WC. The results of the study suggest that the deficiency of vitamin D in the body increases with the aggravation of hormonal dysfunction in PCOS, which should be taken into account by specialists during the management of this category of patients and the treatment of infertility.
