Summary
This summary is machine-generated.Excess iodine intake is linked to poorer bone health. Higher iodine levels correlate with lower bone mineral density (BMD) and increased risk of osteopenia and osteoporosis.
Area Of Science
- Endocrinology
- Bone Metabolism
- Nutritional Science
Background
- The relationship between iodine nutrition and bone health remains largely unexplored.
- Iodine is crucial for thyroid hormone synthesis, which influences bone metabolism.
Purpose Of The Study
- To investigate the association between iodine nutrition status and bone health parameters.
- To explore the link between iodine intake levels and bone metabolism and disease in adults.
Main Methods
- A cross-sectional survey was conducted in China across iodine fortification, adequate, and excess areas.
- Measurements included urine iodine concentration (UIC), serum iodine concentration (SIC), bone mineral density (BMD), and bone metabolism markers.
- Statistical analyses, including univariate linear regression, were performed.
Main Results
- Individuals in iodine excess areas (IEA) had significantly higher UIC and SIC.
- BMD and calcium levels differed across iodine nutrition levels, with BMD negatively correlated with UIC and SIC.
- High UIC (≥ 300 µg/l) and SIC (> 90 µg/l) were identified as risk factors for osteopenia and osteoporosis.
Conclusions
- Excess iodine intake negatively impacts bone metabolism and BMD.
- Elevated iodine levels are a significant risk factor for developing osteopenia and osteoporosis.

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...
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...
The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...
