Impact of skeletal maturation on bone metabolism biomarkers and bone mineral density in healthy Brazilian male adolescents

Abstract: Objective: To evaluate the behavior of biomarkers of bone formation and resorption in healthy male Brazilian adolescents according to their biological maturation.Methods: Eighty-seven volunteers were divided into age groups according to bone age (BA): 10-12 years (n = 25), 13-15 years (n = 36), and 16-18 years (n = 26). Weight (kg), height (m), body mass index (kg/m 2 ), calcium intake from 3 days assessed by 24-h food recall (mg/day), pubertal event evaluation by Tanner criteria, and serum biomarker levels (o… Show more

“…Bone mineral content increases gradually during childhood and then accelerates during adolescence in both genders, i.e. , the rate of bone formation exceeds the rate of bone resorption, resulting in bone modeling and remodeling [32,33,34,35]. After the cessation of growth, bone mass continues to increase for some years until reaching a peak, which can be defined as the maximum amount of bone mass a person accumulates from birth to skeletal maturity [36,37,38].…”

A densitometria óssea por atenuação de raios X de dupla energia (dual energy X-ray absorptiometry, DXA) tem sido considerada padrão ouro para avaliação de risco de fraturas em mulheres na pós-menopausa 3 .…”

“…A DXA, ainda pouco acessível e de custo elevado, detecta o remodelamento num período mínimo de três a seis meses. Enquanto os biomarcadores retratam o metabolismo ósseo no momento, fornecendo avaliações rápidas, confiáveis e precoces da redução da massa óssea 1,2,5 . Contudo, estes últimos têm sido mais tradicionalmente utilizados em acompanhamentos de tratamentos 6 do que propriamente em diagnósticos.…”
