Objective: The objective of the present study was to determine if body mass index and vitamin D levels are risk factors for the development of uterine leiomyomas in Mexican women. Methods: A cross-sectional study was designed. Inclusion criteria were women between 20 and 55 years with a suspect of uterine leiomyomas. Transvaginal ultrasonography was made to confirm the diagnosis and clinical variables were collected. Vitamin D levels were measured in serum by chemiluminescence immunoassay. Binary linear regression analysis was conducted to assess the predictors of uterine leiomyomas. Results: A total of 106 patients were evaluated, the mean age was 41.4 ± 8.0 years. The serum levels of vitamin D were insufficient in 94 (88.7%) and 82 (77.3%) has overweight or obesity. However, only 50 (47.2%) of participants have a diagnostic of uterine leiomyomas. BMI not increased the probability of having insufficient levels of vitamin D or uterine leiomyomas. Only, age (> 45 years) and levels of vitamin D (<30 ng/mL) were predictors of uterine leiomyomas (OR 10.345, 95% CI 2.737–39.095; p = 0.001; and OR 2.26, 95% CI 1.011–5.073; p = 0.014), respectively. Conclusions: Insufficient levels of vitamin D are common in Mexican women. Age and hypovitaminosis D are possible risk factors in the development of uterine leiomyomas in Mexican women.

We assessed the association between several cardiometabolic risk factors (CRFs) (blood pressure, LDL-cholesterol, HDL-cholesterol, triglycerides, uric acid, and glucose) in 390 young adults aged 19-20 years in Seychelles (Indian Ocean, Africa) and body mass index (BMI) measured either at the same time (cross-sectional analysis) or at the age of 12–15 years (longitudinal analysis). BMI tracked markedly between age of 12–15 and age of 19-20. BMI was strongly associated with all considered CRFs in both cross-sectional and longitudinal analyses, with some exceptions. Comparing overweight participants with those having a BMI below the age-specific median, the odds ratios for high blood pressure were 5.4/4.7 (male/female) cross-sectionally and 2.5/3.9 longitudinally (P<0.05). Significant associations were also found for most other CRFs, with some exceptions. In linear regression analysis including both BMI at age of 12–15 and BMI at age of 19-20, only BMI at age of 19-20 remained significantly associated with most CRFs. We conclude that CRFs are predicted strongly by either current or past BMI levels in adolescents and young adults in this population. The observation that only current BMI remained associated with CRFs when including past and current levels together suggests that weight control at a later age may be effective in reducing CRFs in overweight children irrespective of past weight status.

Objective To investigate risk factors associated with hypovitaminosis D in adult patients infected with HIV/aids, at a referral hospital in Maceió, Brazil. Subjects and methods This cross-sectional study involved 125 patients evaluated from April to September 2013 by means of interviews, review of medical records, physical examination, and laboratory tests. The data were analyzed using the SPSS® software, version 17.0; the prevalence of hypovitaminosis D and mean levels of vitamin D were determined. The association between hypovitaminosis D and the independent variables was assessed using the Chi-square or the Fisher’s exact tests; mean vitamin D concentrations were analyzed using Kolmogorov-Smirnov, Mann-Whitney, and Kruskal-Wallis tests. The level of significance was set at 5% across tests. Results The prevalence of hypovitaminosis D was 24%, with a significant association with higher household income (p < 0.05). Higher vitamin D levels were associated with female gender (p < 0.001), no use of sunscreen (p < 0.05), and previous opportunistic infections (p < 0.01). Lower values were associated with the use of antiretroviral medication (p < 0.05), overweight and obesity (p < 0.01). Conclusion Lower vitamin D concentrations were significantly associated with well-known risk factors for hypovitaminosis D: use of sunscreen, antiretroviral medication, overweight, and obesity. The prevalence of hypovitaminosis D in this study, considering values > 20 ng/mL or > 30 ng/mL as vitamin D sufficiency, was lower to that of previous studies with HIV-infected patients, a fact that might be related to the low latitude and high intensity of solar radiation of the location of the present study.

Objective: To determine frequency of vitamin D deficiency in patients presenting with fibromyalgia and its association with various factors. Study Design: Cross sectional study. Place and Duration of Study: Medicine department, Pak Emirates Military Hospital Rawalpindi, from Sep 2018 to Feb 2019. Methodology: Ninety patients of fibromyalgia were included in the study. Diagnosis of fibromyalgia was made by the consultant rheumatologist on the basis of American College of Rheumatology Criteria needed for fibromyalgia diagnosis and classification. Vitamin D levels <20ng/ml were considered as deficient. Age, education, marital status, menstrual abnormallities and body mass index were correlated with the presence of vitamin D deficiency among the patients suffering from fibromyalgia. Results: Out of 90 patients of fibromyalgia, 57 (63.3%) showed the presence of vitamin D deficiency while 33 (36.7%) had no deficiency of vitamin D. Among the study participants 88 (97.8%) patients were females and only 2 (2.2%) patients were males. Mean age of the patients was 39.4 ± 3.365 years. After applying the binary logistic regression, we found that presence of menstrual abnormalities and high body mass index had significant association with the presence of vitamin D deficiency among the patients of fibromyalgia (p-value<0.05). Conclusion: Vitamin D deficiency emerged as a common finding among the patients of fibromyalgia in a teaching hospital of Pakistan. Vitamin D deficiency should be screened at the rheumatology clinics and special attention should be paid to the patients who are overweight or obese and female patients with the menstrual abnormalities.

Abstract Purpose Peripheral neuropathy (PN) is common in patients with multiple myeloma (MM). We hypothesized that the relationship between hypovitaminosis D and PN described in diabetes mellitus patients may also be present in MM patients. Methods To study this potential association, we assessed the incidence of hypovitaminosis D (vitamin D < 75 nmol/L [= 30 ng/mL]) in smouldering and active MM patients in two Dutch hospitals. Furthermore, a validated questionnaire was used to distinguish different PN grades. Results Of the 120 patients included between January 2017 and August 2018, 84% had an inadequate vitamin D level (median vitamin D level 49.5 nmol/L [IQR 34–65 nmol/L]; mean age: 68 years [SD ± 7.7]; males: 58%). PN was reported by 69% of patients (n = 83); however, of these 83 patients, PN was not documented in the medical records of 52%. An association was found between lower vitamin D levels and higher incidence of PN in the total population (P = 0.035), and in the active MM patients (P = 0.016). Conclusion This multi-centre cohort study showed that PN and hypovitaminosis D are common in MM patients, and addressing low vitamin D levels in the treatment of MM patients might be beneficial in reducing the risk of PN. More attention for PN is warranted, as PN is underreported by clinicians. Further research is needed to fully understand the implications of vitamin D in the development of PN in patients with MM.

Background: In Covid-19 infection, leukopenia, inflammation, and elevated liver enzymes are found in most patients. Also, vitamin D deficiency attenuate the immune system and predispose a person more susceptible to infection. In this context, we aimed to evaluate vitamin D, Electrolytes, Complete blood count, Liver enzymes, Urea, Creatinine, Albumin, CRP and ESR levels in patients with Covid-19. Methods: We conducted a cross-sectional study on 118 patients with Covid-19 who were hospitalized from 2020/2/19 to 2020/4/3 in ICU. Serum levels of electrolytes, liver enzymes, blood factors, urea, creatinine, CRP and ESR as well as anthropometric parameters and serum vitamin D concentration were measured. Results: A total of 118 patients (80 male and 38 female) was enrolled in the study (65.05±15.75 years). Only 5.08% of patients had no risk factors and 55.9% had ≥ 2 risk factors. Diabetes (44.1%) and obesity (23.7%) were more common among patients. Laboratory finding showed that 80.50% of patients had hyponatremia, but other electrolytes included K, Mg, Ca and P were normal in majority of participants as well as CBC, Cr, Urea, Alb, ALT and ALKP. The AST concentration increased in most patients (66.94%). All patients had high levels of inflammatory factors such as CRP and ESR. The mean of 25-hydroxy-vitamin D levels in participants (25.95 ± 14.56 ng/mL) was lower than its levels in general papulation. However, it was not statistically significant (P= 0.88). A significant negative correlation found between vitamin D and ALT (P= 0.02, -0.21) as well as vitamin D and CRP (P= 0.05, -0.17). Conclusion: Regarding to the regulatory role of vitamin D in immune system and low levels of vitamin D in Covid-19 infected patients, the evaluation of vitamin D levels and prescribe supplements if necessary is suggested.

Today, due to recent developments in technology, children devote plenty of time for screen viewing. However, its harmful effects are not yet clear. The purpose of present study was to examine the associations among screen viewing and sleep duration, and body mass index (BMI) in under-five years old children. This cross-sectional study was conducted with 322 under-five healthy children that were selected using multistage stratified cluster sampling method in 2017. The data that were gathered by time-use diary method were analyzed using Kolmogorov-Smirnov test, Spearman correlation tests, multiple linear regression analysis, one-way ANCOVA, two-way ANCOVA. There was a negative correlation between screen time and sleep duration (rs = -0.42, p = 0.00), positive correlation between screen time and BMI (rs = 0.38, p = 0.00) and sleep duration negatively correlated with BMI (rs = -0.22, p = 0.00). screen viewing was a predictive factor for both sleep duration (&beta; = -0.26, p = 0.00) and BMI (&beta; = -0.26, p = 0.00). screen viewing had a significant impact on sleep duration (4, 314) = 5.02, P = 0.001) and BMI (F (4, 314) = 1.16, P=0.298). Results of this study indicated that screen viewing is related to sleep duration and BMI in under-five children. furthermore, screen time has an impact on sleep duration and BMI scores of children. findings of our study suggest that sleep duration negatively is associated with BMI in under-five-year-old children.

Correlations between aerobic capacity, obesity, and atherosclerotic risk factors were evaluated in adolescents with low-to-moderate levels of physical fitness. Subjects with higher levels of fitness had a more favorable risk profile with decreased body mass index, lower systolic and diastolic blood pressure and plasma triglyceride levels, and higher plasma high-density lipoprotein-cholesterol levels. Simple linear regression analysis revealed an association between body mass index and blood pressure, plasma triglyceride and plasma highdensity lipoprotein-cholesterol. The level of aerobic fitness as determined by exercise duration was also associated with the same atherosclerotic risk factors. However, multiple linear regression analysis demonstrated that body mass index provided the largest explanation, by those variables examined, of the interindividual variance in blood pressure, plasma triglyceride, and high-density lipoprotein-cholesterol. Aerobic fitness contributed only minimally to the variation in these risk factors. These findings suggest that if aerobic conditioning is used to modify atherosclerotic risk factors, it should be accompanied by a reduction in weight in adolescents with low-to-moderate levels of physical fitness.
