Objective: Our main goal was to
present normal BMD measurements in
pubertal males and females in order to make contribution to the the database of normative BMD values in our country.

Methods:
In this study 30 pubertal subjects (14 males, 16 females) with Tanner stage
II-V having normal
BMD values were enrolled. The mean ages of the male and female groups were 13.6±1.4 and
13.7±1.6 years, respectively (P>0.05). The BMD
measurements of lumbar spine (L1-4) and femoral neck were done by dual x-ray
absorptiometry (DXA). Lumbar and femoral BMD measurements of male and female
subjects were compared. Lumbar and femoral neck BMD values were correlated with
the age, weight, height and body mass index of the subjects within each gender
groups.

Results: There
was no significant difference between mean ages, mean weight, mean height and
mean BMI of male and females (P>0.05). The mean lumbar BMD value was statistically higher in pubertal females
compared to males (P<0.05). 
There was significant correlation between the mean age and the mean lumbar
BMD measurements in female group (P<0.05). There was significant correlation
between the mean weight and the mean BMD measurements (lomber and femoral BMD)
in male group (P<0.05).

Conclusion:
In conclusion, DXA is a useful, fast and accurate diagnostic tool for
performing BMD measurements of lumbar spine (L1-4) and femoral neck in pubertal
males and females.

Puberte Dönemindeki Erkeklerde ve Kızlarda Normal Kemik Mineral Yoğunluk Ölçümleri: Kesitsel Bir Dxa Çalışması

Öz

Amaç: Ülkemizdeki
normal kemik mineral yoğunluğu (KMY) veritabanına katkıda bulunmak için  puberte
dönemindeki erkeklerde ve kızlarda normal kemik mineral yoğunluk (KMY)
ölçümlerini sunmayı amaçladık.

Gereç ve Yöntem: Bu
çalışmaya puberte döneminde olan, normal KMY değerlerine sahip, Tanner evre 2-5
arasındaki 30 olgu (14 erkek, 16 kız) dahil edildi. Erkek ve kız gruplarının
yaş ortalamaları sırasıyla 13.6±1.4 and 13.7±1.6 yıl idi (p>0.05).
Lomber (L1-4) ve femur boynu KMY ölçümleri dual enerji X-ışını absorbsiyometri (DXA) ile yapıldı. Erkek ve kızların
lomber ve femoral KMY ölçümleri karşılaştırıldı. Her cinsiyet grubu içinde
lomber ve femoral KMY değerleri yaş, ağırlık, boy ve vücut kitle indeksi (VKİ)
ile korele edildi.

Bulgular: Erkek ve kızların ortalama yaşları, ağırlıkları, boyları
ve VKİ’leri arasında anlamlı farklılık bulunmadı (P>0.05).
Pubertal kızların ortalama lomber KMY değerleri erkeklerinkinden anlamlı olarak
daha yüksekti (P<0.05).  Kızların
grubunda ortalama yaş ile ortalama lomber KMY ölçümleri arasında anlamlı
korelasyon mevcuttu (P<0.05). Erkeklerin grubunda ortalama ağırlık ile
ortalama KMY ölçümleri (lomber ve femoral) arasında anlamlı korelasyon mevcuttu
(P<0.05).

Sonuç:  Sonuç olarak DXA, pubertal erkek ve kızlarda
lomber (L1-4) ve femur boynu KMY ölçümlerinde yararlı, hızlı ve doğruluğu
yüksek bir tanısal araçtır.
