Investigation of Metacarpal Bone Morphology in Normal-weight, Overweight and Obese Adolescent Subjects

Objective: The prevalence of childhood and adolescent overweight and obesity is increasing in most developed countries. This study aimed to investigate the metacarpal bone morphology in normal-weight, overweight and obese adolescent subjects at different pubertal stages.Materials and Methods: This radiographic study was performed in 124 subjects at different pubertal stages. The subjects were divided into three groups based on body mass index percentile: normal-weight, overweight and obese. The second and fourth metacarpal bone cortical thickness, width and metacarpal index (MCI) were measured on left hand-wrist radiographs. Results: The values of the second and fourth metacarpal bone cortical thickness and width were significantly different among the groups. The second metacarpal bone MCI was significantly different among the groups. Moreover, the values of the second and fourth metacarpal bone cortical thickness, width and MCI in obese and overweight subjects were greater than those in normal-weight subjects. The values of the second and fourth metacarpal bone cortical thickness and width were significantly different in subjects before and after their pubertal growth peak period. Conclusion: The metacarpal bone parameter in overweight and obese adolescent subjects was significantly greater than that in normal-weight subjects.

Normal Kilolu, Aşırı Kilolu ve Obez Adölesan Bireylerde Metakarpal Kemik Morfolojisinin İncelenmesi

Amaç: Gelişmiş ülkelerde çocuk ve adölesanlarda aşırı kilo ve obezite prevalansı artmaktadır. Bu çalışmanın amacı, farklı pubertal dönemlerde normal kilolu, aşırı kilolu ve obez adölesanlarda metakarpal kemik morfolojisini araştırmaktır. Gereç ve Yöntemler: Bu radyografik çalışmaya, farklı pubertal aşamalarda 124 birey dahil edildi. Olgular vücut kitle indeksi yüzdesine göre normal kilolu, fazla kilolu ve obez bireyler olmak üzere üç gruba ayrıldı. Sol el-bilek radyografilerinde ikinci ve dördüncü metakarpal kemiklerde kortikal kalınlık, genişlik ve metakarpal indeks (MKİ) ölçümleri yapıldı. Bulgular: İkinci ve dördüncü metakarpal kemiklerde kortikal kalınlık ve genişlik gruplar arasında anlamlı olarak farklı bulundu. Gruplar arasında ikinci metakarpal kemik MKİ’de anlamlı bir fark tespit edildi. İkinci ve dördüncü metakarpal kemiğin kortikal kalınlığı, genişliği ve MKİ değerleri obez ve fazla kilolu bireylerde, normal kilolu bireylere göre daha yüksekti. Pubertal büyüme atılımı öncesi ve sonrasında ikinci ve dördüncü metakarpal kemiğin kortikal kalınlık ve genişlik değerlerinde anlamlı farklılıklar bulundu. Sonuç: Aşırı kilolu ve obez adolesan bireylerde, normal kilolu bireylere göre anlamlı derecede daha yüksek metakarpal kemik parametresi bulunmaktadır.
