Osteosarcopenic Obesity

Abstract Osteosarcopenic Obesity (OSO) is the concurrent presence of obesity (excess body fat), sarcopenia (low muscle mass) and osteoporosis (low bone mineral density). Low levels of serum vitamin D (vitD) have been associated with each disease and their simultaneous presence. We examined this association in adults aged ≥50 years from the 2001-2006 survey cycles of the National Health and Nutrition Examination Survey (NHANES) (N=3791). SAS v9.4 complex survey procedures were used. Demographics and vitD status were compared across OSO components (0,1,2,3) by chi-squared tests and ANOVAs. Odds ratios and 95% confidence intervals for the association between vitD status and increasing number of OSO components were calculated using multinomial logistic regression (alpha=0.05). The mean age was 65.0 years (30% were older adults ≥ 65), 45.6% were female, and prevalences for obesity, osteoporosis, sarcopenia and OSO were 84.7%, 8.0%, 16.3%, and 1.8%, respectively. Additionally, 30.9% of the sample was vitD deficient. After adjusting for supplement use, and race, women with 1 or 2, and men with 1,2 or 3 OSO components were more likely to be vitD deficient than sufficient, compared to those with none [women: 2.8(1.4-5.7), 2.1(1.4-6.8), and men: 2.3 (1.5-3.6), 3.5(2.1-5.9) and 6.3(1.0-38.5), respectively]. Vitamin D status was associated with having one or two OSO components in women, and OSO and components in men, after adjusting for supplement use, sex, and race. These results suggest it is important to consider obesity, osteoporosis, and sarcopenia jointly with respect to vitamin D status in the chronic disease management of aging and older adults.

Dietary Records

Vitamin D is essential for maintaining calcium homeostasis and optimizing bone health. Its inadequacy is related to many factors including dietary intake. The aim of the present study was to evaluate serum 25(OH)D and its relationship with nutrient intakes in postmenopausal Brazilian women with osteoporosis. This cross-sectional study comprised 45 free-living and assisted elderly at São Paulo Hospital. Three-day dietary records were used to assess dietary intakes. Bone mineral density was measured with a dual-energy X-ray absorptiometer (DXA). Blood and urine sample were collected for analysis of biochemical markers of bone and mineral metabolism. Insufficiency of vitamin D was observed in 24.4% of the women and optimal levels (≥ 50 nmol/L) were observed in 75.6%. Parathyroid hormone was above the reference range in 51% of the participants. The mean calcium (724 mg/day) and vitamin D (4.2 μ g/day) intakes were lower than the value proposed by The Food and Nutrition Board and sodium intake was more than two-fold above the recommendation. Higher levels of serum 25(OH)D were inversely associated with sodium intake. Dietary strategies to improve serum vitamin D must focus on increasing vitamin D intake and should take a reduction of sodium intake into consideration.

Vitamin D Levels

Thyroid hormones have a catabolic effect on bone homeostasis. Hence, this study aimed to evaluate serum vitamin D, calcium, and phosphate and bone marker levels and bone mineral density (BMD) among patients with different thyroid diseases. This cross-sectional study included patients with underlying thyroid diseases (n = 64, hyperthyroid; n = 53 euthyroid; n = 18, hypothyroid) and healthy controls (n = 64). BMD was assessed using z-score and left hip and lumbar bone density (g/cm2). The results showed that the mean serum vitamin D Levels of all groups was low (<50 nmol/L). Thyroid patients had higher serum vitamin D levels than healthy controls. All groups had normal serum calcium and phosphate levels. The carboxy terminal collagen crosslink and procollagen type I N-terminal propeptide levels were high in hyperthyroid patients and low in hypothyroid patients. The z-score for hip and spine did not significantly differ between thyroid patients and control groups. The hip bone density was remarkably low in the hyperthyroid group. In conclusion, this study showed no correlation between serum 25(OH)D levels and thyroid diseases. The bone markers showed a difference between thyroid groups with no significant difference in BMD.

AbstractObjectiveTo assess vitamin D status among Cypriot adolescents and investigate potential determinants including BMI and body fat percentage (BF%).DesignParticipants had cross-sectional assessments of serum vitamin D, physical activity, dietary vitamin D intake and sun exposure. Linear and logistic regression models were used to explore the associations of vitamin D with potential predictors.SettingHospitals, Cyprus, November 2007–May 2008.SubjectsAdolescents (n 671) aged 16–18 years.ResultsMean serum vitamin D was 22·90 (sd 6·41) ng/ml. Only one in ten children had sufficient levels of vitamin D (≥30 ng/ml), while the prevalence of vitamin D deficiency (12–20 ng/ml) and severe deficiency (<12 ng/ml) was 31·7 % and 4·0 %, respectively. Lower vitamin D was associated with winter and spring season, female gender, reduced sun exposure in winter and darker skin. Participants with highest BMI and BF% when compared with a middle reference group had increased adjusted odds of vitamin D insufficiency (OR = 3·00; 95 % CI 1·21, 7·45 and OR = 5·02; 95 % CI 1·80, 13·97, respectively). A similar pattern, although not as strong, was shown for vitamin D deficiency with BF% (OR = 1·81; 95 % CI 1·04, 3·16) and BMI (OR = 1·51; 95 % CI 0·85, 2·67). Participants in the lowest BMI and BF% groups also displayed compromised vitamin D status, suggesting a U-shaped association.ConclusionsVitamin D deficiency in adolescence is very prevalent in sunny Cyprus, particularly among females, those with darker skin and those with reduced sun exposure in winter. Furthermore, vitamin D status appears to have a U-shaped association with adiposity measures.

Objective The objective of this article is to evaluate whether statin use and vitamin D status is associated with severe headache or migraine in a nationally representative sample. Methods We conducted a cross-sectional study of US individuals aged ≥40 years for whom information on statin use, serum 25-hydroxy vitamin D (25(OH)D), and self-reported severe headache or migraine had been collected. We calculated prevalence estimates of headache according to statin and 25(OH)D, and conducted adjusted logistic regression analyses stratified by the median 25(OH)D (≤57 and >57 nmol/l). Results Among 5938 participants, multivariable-adjusted logistic regression showed that statin use was significantly associated with a lower prevalence of severe headache or migraine (OR 0.67; 95% CI 0.46, 0.98, p = 0.04). We found a significant interaction between statin use and 25(OH)D with the prevalence of severe headache or migraine ( p for interaction = 0.005). Among participants who had serum 25(OH)D > 57 nmol/l, statin use was associated with a multivariable-adjusted odds ratio of 0.48 (95% CI 0.32, 0.71, p = 0.001) for having severe headache or migraine. Among those with 25(OH)D ≤ 57 nmol/l, no significant association was observed between statin use and severe headache or migraine. Conclusion Statin use in those with higher serum vitamin D levels is significantly associated with lower odds of having severe headache or migraine.

Background: Present study was designed by keeping in view the importance of vitamin D in adolescents’ age group. Objectives: To explore the cases of low vitamin D status (<50 nmol/l) with respect to age & sex factors in school students. Study Design: Observation cross-sectional study. Setting: Department of Biochemistry faculty of Health Sciences, Hazara University Mansehra, Ayub Medical College and Teaching Hospital Abbottabad. Period: June 2014 to June 2015. Subject & Methods: We recorded daily intake of vitamin D of each individual and  measured serum 25 hydrxoy vitamin D in a school based cross sectional sample of adolescents girls (n=93) and boys (n=96) students. Results: Results of this study reflected that, out of total boys and girls students, 16% and 39% of the sample  respectively showed low serum vitamin D status(<50 nmol/l). Number of cases had low vitamin D level increased with age in girls and decreased with age in boys. Serum vitamin D concentration was decreased with increase in age of girls and found significantly low (p=0.0087) in higher age group (>13-≤16).  No significant difference (p=0.29) was noted regarding daily intake of vitamin D between lower & higher age. Conclusion: It is concluded that, age and sex might be contributory factors in the occurrence of low vitamin D status.
