We have recently hypothesized that low vitamin D status may contribute to the pathogenesis of congestive heart failure (CHF). This study was aimed at evaluating, in a pilot study, whether CHF patients have indications for a low vitamin D status during earlier periods of their lives. We performed a case-controlled study in 150 CHF patients and 150 controls. Study participants had to answer a questionnaire that included several items concerning vitamin D-associated lifestyle factors during childhood, adolescence, and adulthood. A vitamin D score was constructed. This score takes into consideration that ultraviolet-B (UVB) exposure is the major vitamin D source for humans and that those lifestyle factors, which are associated with regular UVB exposure, can guarantee an adequate vitamin D status at best. The vitamin D score was significantly higher in controls than in patients (p < 0.001). Compared with the controls, more patients lived in large cities (p < 0.001), fewer patients were members of a sport club (p < 0.001), and fewer patients had summer holidays every year (p < 0.01). Patients also reported significantly less alcohol consumption during adulthood than controls (p < 0.001). Our results demonstrate that CHF patients and controls differed in several vitamin D-associated lifestyle factors and in alcohol consumption during earlier periods of their lives.

Modifiable Lifestyle Factors

Studies on vitamin D status and its determinants in growing children in countries with ample sunshine such as Malaysia have been limited. The aim of our study was to determine factors associated with serum 25(OH)D concentrations such as lifestyle, dietary intake, anthropometry, and body composition in 243 pre-adolescent Malaysian children from low-income families living in Kuala Lumpur. This cross-sectional study measured bone density and body composition using dual-energy X-ray absorptiometry (DXA), while serum 25(OH)D was measured using LC–MS/MS. Time spent outdoors, body surface area exposed to sunlight, dietary intake, and physical activity level were assessed using questionnaires. Multiple linear regression and stepwise analysis were performed to identify significant predictors for serum 25(OH)D. About 69.4% had 25(OH)D < 50 nmol/L, and 18.9% were vitamin-D-deficient with 25(OH)D < 30 nmol/L. Girls had a nine-fold higher prevalence of vitamin D deficiency than boys. Body surface area exposed to sunlight, Sun Index, and fat mass were significant predictors of 25(OH)D concentrations in this population. Modifiable lifestyle factors such as sun exposure and reducing obesity are important public health guidance to ensure optimal vitamin D status in these children.

Abstract Background Vitamin D has been identified as a potential protective factor in the development of colorectal cancer (CRC). We expect to see a stronger association of ultraviolet B (UVB) exposure and CRC crude rates with increasing age since chronic vitamin D deficiency leads to sustained molecular changes that increase cancer risk. The DINOMIT (disjunction, initiation, natural selection, overgrowth, metastasis, involution, and transition) model postulates various stages of cancer development due to vitamin D deficiency and the associated latency period. The purpose of this study is to examine this age-dependent inverse relationship globally. Methods In this ecological study, a series of linear and polynomial regression tests were performed between country-specific UVB estimates adjusted for cloud cover and crude incidence rates of CRC for different age groups. Multiple linear regression was used to investigate the association between crude incidence rates of colorectal cancer and UVB estimate adjusting for urbanization, skin pigmentation, smoking, animal consumption, per capita GDP, and life expectancy. Statistical analysis was followed by geospatial visualization by producing choropleth maps. Results The inverse relationship between UVB exposure and CRC crude rates was stronger in older age groups at the country level. Quadratic curve fitting was preferred, and these models were statistically significant for all age groups. The inverse association between crude incidence rates of CRC and UVB exposure was statistically significant for age groups above 45 years, after controlling for covariates. Conclusion The age-dependent inverse association between UVB exposure and incidence of colorectal cancer exhibits a greater effect size among older age groups in global analyses. Studying the effect of chronic vitamin D deficiency on colorectal cancer etiology will help in understanding the necessity for population-wide screening programs for vitamin D deficiency, especially in regions with inadequate UVB exposure. Further studies are required to assess the need for adequate public health programs such as selective supplementation and food fortification.

BACKGROUND: Few studies have examined the relationship between vitamin D levels and incident cardiovascular events in large well-characterized type 2 diabetes cohorts. METHODS: We performed prospective analyses to determine associations between vitamin D status and vascular endpoints among 936 Veterans Affairs Diabetes Trial (VADT) participants (mean age 59.7 years; 96.7% male; 40.4% minority). 25 (OH)-vitamin D was measured a median of two years after entry into the VADT study and participants were subsequently followed an average of 3.7 years for outcomes. Cox proportional hazard models were used to calculate hazard ratios (HRs) for macrovascular endpoints in relation to vitamin D quartile. The primary composite endpoint included documented myocardial infarction; stroke; death from cardiovascular causes; new or worsening congestive heart failure; surgical intervention for cardiac, cerebrovascular, or peripheral vascular disease; inoperable coronary artery disease; and amputation for ischemic gangrene. RESULTS: On average VADT participants had high cardiovascular risk at entry into the study: 65.3% of the patients recruited were obese, 38.5% had previously had a vascular event, 78.7% had hypertension and 59.5% were using statins. During follow-up, 17.2%, 5.0%, 5.9%, 2.4% and 6.6% of participants had a primary composite endpoint, myocardial infarction, chronic heart failure, cardiovascular death or all-cause death, respectively. After adjusting for age, minority status, treatment arm and history of prior event, individuals in the lowest quartile of vitamin D (i.e., 1 to 15.9 ng/ml) were at similar risk of the primary composite endpoint [HR=1.26 (95% CI: 0.81, 1.96)], myocardial infarction [HR=1.13 (95% CI: 0.53, 2.42)], congestive heart failure [HR=1.44 (95% CI: 0.67, 3.06)], cardiovascular death [HR=0.86 (95% CI: 0.28, 2.63)], and death from any cause [HR=1.04 (95% CI: 0.53, 2.04)] as individuals in the highest quartile of vitamin D (i.e., 29.9 to 77.2 ng/ml). CONCLUSIONS: These data indicate that vitamin D status had no significant impact on the incidence of macrovascular events in a cohort of high-risk veterans with type 2 diabetes mellitus in which traditional risk factors were managed according to current treatment guidelines.

Introduction: Vitamin D deficiency has been linked to the increased risk of several chronic diseases, especially in people living in the Northern Latitudes. The aim of this study was to assess the vitamin D status in older subjects born in 1945 in Northern Finland (latitude 65°North), and to examine its associations to components of metabolic syndrome (MetS). Methods: In this cross-sectional study, we invited 904 subjects born in 1945 from the Oulu region (Oulu45 cohort), out of an original cohort of 1332 subjects. In the cohort, plasma 25 hydroxyvitamin D (25OHD) levels were determined by an enzyme immunoassay of 263 men and 373 women, with a mean age baseline of 69±0.5 years old. We assessed the participants’ usage of vitamin D supplements, as well as their lifestyle factors, using a questionnaire. Results: Nearly 80% of the subjects had low vitamin D levels [either vitamin D deficient (<50 nmol/L) or insufficient (50 – 75 nmol/L)], and only 20% of the participants had sufficient vitamin D levels (>75 nmol/L) (based on the American Endocrine Society guidelines). The low vitamin D status was associated with a high prevalence of MetS; a significantly higher number of subjects with MetS (41%) had low vitamin D levels in comparison to the non-MetS subjects (38%) (p ≤ 0.05). The subjects under vitamin D supplementation had a significantly lower incidence of MetS (42.6% vs 57.4%) and its components in comparison to the non-supplemented subjects (p ≤ 0.05). Conclusions: Low vitamin D levels are a risk factor for MetS amongst other lifestyle factors, such as dietary habits and physical inactivity, among older subjects in the Northern Latitudes (65°North). Optimal supplementation of vitamin D, along with rich dietary sources of vitamin D, are highly recommended for older subjects as a means to positively affect, e.g., hypertension, insulin resistance, and obesity, as components of the MetS.
