“…It has been established that the level of low income per family member increases by 1.31 times the likelihood of vitamin deficiency in adolescents (p = 0.015). The findings confirm the results of other studies conducted in different countries, but in our case, the risk ratio was 1.36, while in the USA it was 1.6 13 , and in Canada 3.14 14 .…”

“…The data obtained during the study showed a similar trend of change in the status of vitamin D in children of different ages during epidemiological studies in Ukraine, but were lower compared with the data of the studies in the USA, Spain, and Italy 5,9 . Researchers explain the low levels of 25 (OH) D in blood serum by depositing calcidiol in the adipose tissue, reducing bioavailability, and reducing its synthesis under the influence of ultraviolet rays 14 .…”

“…Anthropometric examinations -body weight (within the accuracy of 0.1 kg), height (within the accuracy of 0.1 cm) -were carried out, with the use of generally accepted methods with the help of floor weight, height meter and flexible centimeter tape. BMIs were evaluated according to standard percentile tables 5,14 . Thus, children with BMI from 15 to 85 percentiles were assigned to the normal body mass, the excess body mass corresponded to 85-95 percentiles and over 95 percentiles -to the obesity.…”

“…Moreover, attention is drawn to the fact that with an increase in the amount of adipose tissue there is a limitation of the bioavailability of vitamin D, which is associated with its engulfment by adipocytes and deposition in the adipose tissue. Thus, Spanish researchers have discovered the relations between a low-level of 25(OH)D in serum and high triglyceride levels, regardless of age, sex, body mass index and physical activity 14 .…”

“…There are scientific papers presenting results similar to ours, published by many researchers, who indicate that vitamin D deficiency is most prevalent among children suffering from overweight and obesity [12][13][14]. It is believed that with excessive amounts of adipose tissue the sequestration of calcidiol increases within it, resulting in vitamin D deficiency [8,12].…”

Introduction: In the case of obesity and excessive body weight, the deficiency of vitamin D increases, which significantly impairs metabolic processes in the body, especially fatty and carbohydrate metabolism. Vitamin D metabolites affect insulin sensitivity of cells. The aim of the study was to determine the relationship between vitamin D and carbohydrate metabolism in adolescents with excessive body weight and obesity. Material and methods: 139 adolescents were examined. The mean age of children was 15.5 ±2.3 years. 65 adolescents with excessive weight and 74 obesity teenagers were examined. Parameters that were determined in all children included: undertaking anthropometric measurements, general examinations, biochemical parameters, including carbohydrate metabolism: fasting glucose, insulin, oral glucose tolerant test, measuring the homeostasis model assessment for insulin resistance, blood pressure measurement and determination of vitamin D status. Results: The features of changes carbohydrate metabolism markers in adolescents with overweight and obesity, depending on the level of serum 25(OH)D, have been established. Correlations between vitamin D status and markers of carbohydrate metabolism such as basal insulin level (p = 0.000) and HOMA-IR index (p = 0.000) and anthropometric indices: body mass index (p = 0.000), waist circumference (p = 0.000) and hip circumference (p = 0.001), waist-hip ratio (p = 0.000), waist-to-height ratio (p = 0.000) have been determined. Conclusions: The study has established prognostically significant biochemical (basal insulin), and anthropometric (body mass index, waist circumference, waist-hip ratio, and waist-to-height ratio) markers resulting in vitamin D deficiency development in children with excessive body weight and obesity.

Calcium is imperative in maintaining a quality life, particularly during later ages. Its deficiency results in a wide range of metabolic disorders such as dental changes, cataracts, alterations in brain function, and osteoporosis. These deficiencies are more pronounced in females due to increased calcium turnover throughout their life cycle, especially during pregnancy and lactation. Vitamin D perform a central role in the metabolism of calcium. Recent scientific interventions have linked calcium with an array of metabolic disorders in females including hypertension, obesity, premenstrual dysphoric disorder, polycystic ovary syndrome (PCOS), multiple sclerosis, and breast cancer. This review encompasses these female metabolic disorders with special reference to calcium and vitamin D deficiency. This review article aims to present and elaborate on available data regarding the worldwide occurrence of insufficient calcium consumption in females and allied health risks, to provide a basis for formulating strategies and population‐level scientific studies to adequately boost calcium intake and position where required.

Overweight and obesity are associated with lower vitamin D status in Canadian children and adolescents

Abstract: This study confirms the inverse association between adiposity and serum concentrations of 25-hydroxyvitamin D in Canadian youth and the independent association of overweight/obesity to 25-hydroxyvitamin D level and vitamin D status after adjustment for other factors.
