Summary
Vitamin D levels in Central Europe are generally below 30 ng/mL, with significant seasonal and age-related variations. Hypovitaminosis D prevalence is comparable to Western Europe.
Area of Science:
- Nutritional Epidemiology
- Public Health
Background:
- Limited epidemiological data exists on vitamin D status in Central Europe.
- Vitamin D deficiency (hypovitaminosis D) is a growing public health concern globally.
Purpose of the Study:
- To review and summarize available data on 25(OH)D concentrations in Central European populations.
- To identify factors influencing vitamin D status in this region.
Main Methods:
- A literature search was conducted for studies on 25(OH)D levels in healthy Central European individuals.
- Included both cross-sectional and longitudinal study designs to assess seasonal variability.
Main Results:
- 25(OH)D concentrations in Central Europe are typically below 30 ng/mL.
- Vitamin D status varies significantly by age, season, and methodology.
- A longitudinal study showed winter levels around 21-23 ng/mL, rising to 42 ng/mL in August for children but only 21 ng/mL for the elderly.
Conclusions:
- Average 25(OH)vitamin D levels in Central European populations are below the recommended 30 ng/mL threshold.
- Age-related decline in vitamin D is linked to reduced sun exposure and synthesis efficiency.
- The prevalence of hypovitaminosis D in Central Europe mirrors that of Western Europe.

01:23Role of Skin in Vitamin D Synthesis
8.1K
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...

01:25Role of Vitamins in Maintaining Bone Health
5.1K
The growth and maintenance of bone are regulated by a combination of nutritional factors, including vitamins, such as vitamin A, B12, C, D, and K.
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

3.4K
Connective tissue develops from the mesoderm of a developing embryo and consists of cells, fibers, and ground substance: a gel-like material containing large complexes of carbohydrates and proteins. Connective tissue was first identified as a separate tissue family in the 18th century, and Johannes Peter Muller coined the term connective tissue.
Fat cells (adipocytes), smooth muscle cells (myoblasts), and bone cells (osteoblasts) are some connective tissue cell types. Some immune system cells...

01:21Skeleton and Calcium Homeostasis
8.4K
Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.

Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...

Understanding serum lipids is crucial for maintaining cardiovascular health and preventing heart disease and stroke.
Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
