During childhood and adolescence, bone mass acquisition occurs primarily through skeletal growth. It is widely assumed that bone mass acquisition throughout childhood is an important determinant of the risk of osteoporosis in late adulthood; bone mass is thought to resemble a bank account in which deposits persist indefinitely. However, several well-controlled clinical studies suggest that incr...

Children with malignancies have low bone mass. Pathways for metabolic bone disease were investigated in children with cancer by concomitantly assessing lifestyle, clinical, and biochemical predictors of bone mass. Forty-one children who were receiving cancer therapy for 61 weeks and 39 controls were studied. Data on lifestyle factors, biochemical and hormonal parameters, dual-energy X-ray absor...

Introduction:There is considerable amount of controversy about the long term effects of multiparity and duration of breast-feeding on maternal bone mineral density after menopause. This study was conducted to determine whether multiple pregnancy and prolonged duration of breast-feeding are independent predictors of low bone mass in post-menopausal Kurdish women. M...

background: we aimed to evaluate the effect of body weight and body mass index (bmi) on bone mineral density (bmd) in healthy postmenopausal iranian women.    material and methods: two hundred postm­enopausal women (age between 51 and 69 years) who had presented to the nuclear medicine center at shariati hospital in tehran, iran between april 2012 and august 2013 were included in this cross sec...

background: low back pain is the most common cause of disability and absence from work among young and middle-aged people. as there is limited knowledge regarding this problem among iranian students, this study aimed to determine the prev­alence of low back pain and its ‘related socio­demographic factors among students of islamic azad university, tehran, iran.    materials and methods: two hu...

Puberty is a crucial time for bone development with a doubling of skeletal mass and at least 90% of bone mineral deposition accrued by the end of adolescence [1]. Following puberty, bone mineral deposition continues with peak bone mass typically obtained around the age of 25 years [2]. The accrual of bone mass during adolescence is a major determinant of peak bone mass [1] and low peak bone mas...
