Sağlıklı Yetişkinlerde Abdominal Obezitenin Vücut Kompozisyonu ve Obezite Belirteçlerine Etkisi
Amaç: Abdominal obezitenin sağlıklı bireylerde vücut kompozisyonu ve obezite belirteçleri olan peptit hormonlar (adropin, ghrelin, obestatin) üzerindeki etkilerini değerlendirerek ileride oluşabilecek metabolik riskler hakkında bilgi sahibi olmaktır.
Gereç ve Yöntem: Çalışma, Amasya Gümüşhacıköy Devlet Hastanesi’ne başvuran 25-52 yaş aralığındaki toplam 69 katılımcı ile yapılmıştır. Katılımcıların aynı merkezde antropometrik ölçümleri ve vücut kompozisyon analizi yapılmış; obezite belirteçleri Amasya Üniversitesi Fen Edebiyat Fakültesi laboratuvarında çalışılmıştır.
Bulgular: Abdominal obez grupta kontrol grubuna kıyasla vücut kitle endeksi (VKİ), bel çevresi, vücut yağ oranı, iç yağlanma, obezite derecesi daha yüksek görülürken; iskelet kas oranı, serum adropin ve ghrelin düzeylerinin daha düşük olduğu görülmüştür. VKİ ve vücut yağ oranı adropin, obestatin ve ghrelin düzeyleri ile negatif korelasyon gösterirken; bel çevresi ve iç yağlanma sadece ghrelin düzeyi ile negatif korelasyon göstermiştir.
Sonuç: İki çalışma grubu arasındaki verilerde anlamlı farklılıklar bulunmuş, antropometrik ölçüm ve vücut kompozisyonunun obezite belirteçlerinin bir veya birkaçıyla korelasyon gösterdiği saptanmıştır. Bu sonuçların gelecekte hormonların obezite ve metabolik risklerle olan ilişkisinin daha iyi anlaşılmasına katkı sağlayacağı düşünülmektedir.
EFFECT OF ABDOMINAL OBESITY ON BODY COMPOSITION AND OBESITY MARKERS IN HEALTHY ADULTS
Aim: To obtain information about future metabolic risks by evaluating the effects of abdominal obesity on body composition and peptide hormones (adropin, ghrelin, obestatin), which are obesity markers, in healthy individuals.
Material and Method: The study was conducted with a total of 69 participants aged 25-52 years who applied to Amasya Gumushacıkoy Public Hospital. Anthropometric measurements and body composition analysis were performed in the same center and obesity markers were studied in Amasya University Faculty of Science and Letters Laboratory.
Results: In the abdominal obese group, BMI, waist circumference, body fat ratio, visceral fat rating and obesity degree were higher, while skeletal muscle ratio, serum adropin and ghrelin levels were lower compared to the control group. Body Mass Index (BMI) and body fat ratio were negatively correlated with adropin, obestatin and ghrelin levels, while waist circumference and visceral fat rating were only negatively correlated with ghrelin levels.
Conclusion: Significant differences were found in the data between the two study groups, and anthropometric measurements and body composition were found to correlate with one or more of the obesity markers. It is thought that these results will contribute to a better understanding of the relationship between these hormones and obesity and metabolic risks in the future.
