Bone mineral density in Egyptian adolescents and adults with short stature: results of a national survey

Little is known about bone mass acquisition among stunted adolescents who did not achieve their growth in height. A national survey was made of bone mineral density among stunted adolescents and adults. A multistage stratified random sample of 2500 families [8476 adolescents and their parents] was selected from 6 governorates in different geographical areas of Egypt. Clinical history, anthropometry and measurement of bone mineral density using dual energy X-ray absorptiometry was done. Mean T-scores were significantly lower among both adults and adolescents with short stature compared with those of normal height. The predictors of bone status among adolescent boys were age, body mass index [BMI], height attained [z-score] and maternal T-score and for girls were BMI, age at menarche, paternal T-score and z-score. Stunted adolescents suffered from low bone mass density and low stature adults suffered a high prevalence of osteoporosis
