Nutrition and bone health: turning knowledge and beliefs into healthy behaviour.
Primary osteoporosis prevention requires healthy behaviours, such as regular physical exercise and adequate dietary intakes of calcium, vitamin D and protein. Calcium and vitamin D can decrease postmenopausal bone loss and prevent fracture risk. However, there is still a high prevalence of calcium and vitamin D insufficiency in women aged 50+ years. Dietary sources of these nutrients are the preferred choice, and dairy products represent a valuable dietary source of calcium due to the high content, high absorptive rate and relatively low cost. Furthermore, dairy products also contain other key nutrients including vitamin D, phosphorus and protein that contribute to bone health. Studies of women's beliefs and behaviours with respect to osteoporosis highlight poor knowledge of the importance of dietary nutrient intakes and low concern regarding bone health. Osteoporosis educational programmes exist to help women change behaviours relevant to bone health. Such programmes can have positive influences on women's knowledge, attitudes, perceived norms, motivation and behaviours. Increased awareness of the consequences of low calcium and vitamin D intakes may promote women's attitudes towards dietary sources, in particular dairy products, and lead to better adherence to health recommendations. Increasing dietary nutrient intakes through educational initiatives should be further developed to aid the prevention of osteoporosis and the efficacy of osteoporosis management.
