Calcium consumption for osteoporosis prevention: knowledge, attitudes and behavior in the northeastern region,
Objective:
Identified Thai adults' knowledge and attitudes towards calcium and determined factors predicting calcium consumption.
Material And Method:
One thousand four hundred seventy five Thai adults, aged > or = 20 years old were interviewed, using a semi-structured questionnaire. Knowledge about role of calcium and good sources of calcium was measured using 17 questions. Attitudes towards calcium were measured with 10 opinion statements, using 7-point Likert scale (1 = strongly disagree to 7 = strongly agree). Calcium consumption, based on a 24-hour recall, was assessed using food frequency checklists and open-ended questions.
Results:
The median score for knowledge was 15 (IQR: 12, 16; total possible score: 17). The overall median of attitudinal score was 5.6 (IQR: 4.9, 6.1; cronbach's alpha = 0.80). Approximately 10.9% consumed adequate amounts of calcium (800 mg/day).
Conclusion:
Factors significantly determining the likelihood an adequate intake of calcium were age < 35 years, support from peers and taking calcium-supplements.

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...

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...
Role of Vitamins in Maintaining Bone Health
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...
