25 Hydroxyvitamin D

BACKGROUND Vitamin D deficiency has been implicated in decreased insulin secretion and increased insulin resistance, hallmarks of type 2 diabetes mellitus. We tested the hypothesis that low plasma 25-hydroxyvitamin D [25(OH)D] is associated with increased risk of type 2 diabetes in the general population. METHODS We measured 25(OH)D in 9841 participants from the general population, of whom 810 developed type 2 diabetes during 29 years of follow-up. Analyses were adjusted for sex, age, smoking status, body mass index, income, physical activity, HDL cholesterol, and calendar month of blood draw. RESULTS Lower 25(OH)D concentrations, by clinical categories or seasonally adjusted quartiles, were associated with higher cumulative incidence of type 2 diabetes (trend, P = 2×10−7 and P = 4×10−10). Multivariable adjusted hazard ratios of type 2 diabetes were 1.22 (95% CI 0.85–1.74) for 25(OH)D <5 vs ≥20 μg/L and 1.35 (1.09–1.66) for lowest vs highest quartile. Also, the multivariable adjusted hazard ratio of type 2 diabetes for a 50% lower concentration of 25(OH)D was 1.12 (1.03–1.21); the corresponding hazard ratio for those ≤58 years old was 1.26 (1.15–1.41). Finally, in a metaanalysis of 16 studies, the odds ratio for type 2 diabetes was 1.50 (1.33–1.70) for the bottom vs top quartile of 25(OH)D. CONCLUSIONS We observed an association of low plasma 25(OH)D with increased risk of type 2 diabetes. This finding was substantiated in a metaanalysis.

Abstract Background Vitamin D deficiency has been associated with type 2 diabetes (T2D) and metabolic syndrome (MS) and its components. However, it is unclear whether a low concentration of vitamin D is the cause or consequence of these health conditions. Thus, this study aimed to evaluate the association of vitamin D concentrations and its genetic risk scores (GRSs) with MS and its component diseases, such as T2D, in middle-aged and elderly participants from rural eastern China. Methods A subset of 2393 middle-aged and elderly individuals were selected from 70,458 participants of the Nantong Chronic Diseases Study of 2017–2018 in China. We used two 25-hydroxyvitamin D (25[OH]D) synthesis single-nucleotide polymorphisms (SNPs) (DHCR7-rs12785878 and CYP2R1-rs10741657) and two 25(OH) D metabolism SNPs (GC-rs2282679 and CYP24A1-rs6013897) for creating GRSs, which were used as instrumental variables to assess the effect of genetically lowered 25(OH) D concentrations on MS and T2D based on the Wald ratio. F statistics were used to validate that the four SNPs genetically determined 25(OH) D concentrations. Results Compared to vitamin D sufficient individuals, individuals with vitamin D insufficiency had an odds ratio (OR [95% confidence interval {CI}]) of MS of 1.30 (1.06–1.61) and of T2D of 1.32 (1.08–1.64), individuals with vitamin D deficiency had an ORs (95% CI) of MS of 1.50 (1.24–1.79) and of T2D of 1.47 (1.12–1.80), and those with vitamin D severe deficiency had an ORs (95% CI) of MS of 1.52 (1.29–1.85) and of T2D of 1.54 (1.27–1.85). Mendelian randomization analysis showed a 25-nmol/L decrease in genetically instrumented serum 25(OH) D concentrations using the two synthesis SNPs (DHCR7 and CYP2R1 genes) associated with the risk of T2D and abnormal diastolic blood pressure (DBP) with ORs of 1.10 (95%CI: 1.02–1.45) for T2D and 1.14 (95%CI: 1.03–1.43) for DBP. Conclusions This one sample Mendelian randomization analysis shows genetic evidence for a causal role of lower 25(OH) D concentrations in promoting of T2D and abnormal DBP in middle-aged and elderly participants from rural China.

Incident Type 2 Diabetes

Background: Animal experiments have suggested that exposure to persistent organic pollutants (POPs) may lead to increased risk of type 2 diabetes. Although recent human studies supported this hypothesis, evidence from prospective investigations is sparse. Objective: To examine the associations of plasma POP concentrations with risk of incident type 2 diabetes in a prospective setting among US women. Methods: Study population was comprised of participants from two independent nested case-control studies in the Nurses’ Health Study, in which major polychlorinated biphenyl (PCB 118, 138, 153, and 180), p-p'- dichlorodiphenyldichloroethylene (DDE), dichlorodiphenyltrichloroethane (DDT), and hexachlorobenzene (HCB) were measured. A non-parametric approach was used to derive standardized scores for plasma concentrations of lipid-adjusted POPs within each study to minimize between-study variation of the POP measurements. Risk of incident type 2 diabetes during the follow-up period (1990-2008) across the tertiles of the scores was examined. Results: Of 1,120 participants, we identified 48 incident type 2 diabetes cases. After adjusting for covariates assessed at blood draw in 1990, including smoking status, body mass index, and total fish intake, plasma HCB concentration was positively associated with type 2 diabetes risk: odds ratio (OR) (95% confidence interval [CI]) was 2.77 (1.17, 6.55, P for trend =0.022) comparing the highest vs. lowest tertile. Other POPs were not significantly associated with diabetes: the ORs (95% CI) were 1.10 (0.51, 2.34, P for trend =0.81) for p-p'-DDE, 0.93 (0.44, 1.95, P for trend =0.86) for DDT, and 0.88 (0.39, 1.97, P for trend =0.76) for sum of the 4 major PCBs, comparing the extreme tertiles. Conclusion: The significant association of plasma HCB concentration with diabetes risk supports a role of POP exposure in the etiology of type 2 diabetes. More prospective data are warranted to confirm these findings.

Abstract Background Immigrants from non-Western countries have a higher prevalence of type 2 diabetes. In addition, immigrants have an increased risk of developing diabetes complications, compared with the general population. Diabetes education programmes facilitate essential knowledge and skills that enable people to manage their condition in daily life. However, fewer immigrants attend and complete diabetes education compared with the general population. The aim of this study is to explore what characterises those who decline and accept participation in diabetes education in relation to ethnicity, household composition and diabetes burden in the family. Methods The study population consisted of adults with type 2 diabetes referred to a municipal diabetes centre (n = 1819). Individual medical record data was linked to national registry data. Descriptive statistics and logistic regression models were applied. Results Preliminary results showed that 23% of individuals from the study population participated in diabetes education. We found no overall differences in participation rates between the general population and non-Western immigrants (24% vs. 18%, P = 0.12). However, when examining the immigrant groups by language (Arabic, Urdu and Turkish), the results indicated a non-significant tendency: Urdu speaking groups’ participation was similar to the general population (24%), whereas Arabic and Turkish speaking groups had lower participation rates (17% and 11%, P = 0.25/0.40). Conclusions The results suggest that there are differences in participation between some immigrant groups and the general population. Increased knowledge about which mechanisms affecting participation in diabetes education programme is required to ensure equal access. Further studies and analyses will explore how immigrants’ social relations enable and/or hamper participation in diabetes education and investigate which factors can be changed to improve participation rates. Key messages There are differences in participation in diabetes education programmes across different ethnic groups, which suggests a need for in-depth analysis into which mechanisms that affect participation. The results will be used to give input for future practices that can increase immigrant’s participation and retention in diabetes education programmes.
