The role of vitamin D and calcium supplementation in the prevention of osteoporotic fractures in the elderly

Prevalência da deficiência, insuficiência de vitamina D e hiperparatiroidismo secundário em idosos institucionalizados e moradores na comunidade da cidade de São Paulo, Brasil

“…Os valores de PTH correlacionam-se de maneira inversa às concentrações de vitamina D tanto em idosos quanto na população jovem, e a alta prevalência Sabendo-se que a reposição de cálcio e vitamina D tem efeito protetor sobre a massa óssea (25)(26)(27)(28)(29), torna-se relevante a identificação de pacientes com risco de hipovitaminose D, para que haja uma adequada reposição atuando como mecanismo preventivo sobre o risco de fratura.…”

Multiple sources of dietary calcium—some aspects of its essentiality

“…Osteoporosis and low-bone mass effects are a major public health threat for an estimated 44 million US women aged 50 and older (10 million individuals already have osteoporosis and 34 million more who have low bone mass) placing them at increased risk for developing the disease according to the National Osteoporosis Foundation (2002) and adequate calcium intake is essential to minimize the rate of bone loss associated with ageing. For example, calcium supplementation (with vitamin D) alone and with estrogen-progesterone calcium has been the mainstay of osteoporosis risk reduction and treatment in both adult women and men (Aloia et al, 1994;Bauwens et al, 1986;Berdanier, 2002;Bucher, 1996;Chapuy et al, 1992;Compston, 1995;DawsonHughes et al, 1992;Heaney, 2001aHeaney, ,b, 2002aHeaney and Nordin, 2002;Nordin, 1997;Recker and Heaney, 2001). Studies of post-menopausal osteoporotic women (Bauwens et al, 1986;Compston, 1995) and studies on the process of bone formation and loss in osteoporosis (National Osteoporosis Foundation, 2002) have found doses of 1.5-2.5 g/day of elemental calcium to be safe.…”

Calcium intakes of 32.5-42.5 mmol (1300-1600 mg) per day have been found to minimize age related fracture risk in the elderly (65 and older) (Heaney, 2001a,b).…”

Efficacy of a Self-Management Program for Osteoporotic Subjects

“…In session 1, It's Never Too Late, it is emphasized that osteoporosis is an inevitable part of aging and that getting enough calcium (1000 mg/day) and vitamin D (600 -800 IU/day) is an important first step in making bones healthier. 17 Getting enough (20 min/day) sunlight is another way of vitamin D synthesis. In session 2, There Is More You Can Do, it is emphasized that osteoporotic patients can take osteoporosis medicine as recommended by their health-care professionals.…”
