Objective:
The purpose of this cross-sectional investigation was to examine (1) gender differences in osteoporosis-related knowledge and beliefs and (2) if these beliefs could predict vigorous physical activity behavior in university students.
Participants:
Male (n = 176) and female (n = 351) university students participated in the study.
Methods:
Participants completed self-report measures of osteoporosis knowledge and health beliefs and vigorous physical activity.
Results:
Regardless of gender, osteoporosis knowledge was relatively poor. Women reported higher knowledge, perceived susceptibility, perceived severity, and calcium barriers, and lower exercise self-efficacy than men. Regression analyses showed that for women, perceived susceptibility, health motivation, and exercise self-efficacy predicted vigorous physical activity, whereas for men, exercise barriers was the only predictor.
Conclusions:
Gender differences in osteoporosis health beliefs appear to be greater in older adults than college-aged students. Interventions designed to increase vigorous physical activity may want to target different beliefs for men and women.

Bone Disorders
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...
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...
Hormones and Bone Tissue
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...
Changes in the Appendicular Skeleton with Age
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
