Abstract
Amaç: Geçtiğimiz on yılda yapılmış olan bilimsel araştırmalar kilo alımının, DNA zincir kırıklarının tamir mekanizmasını değiştirebileceğini göstermiştir. Ayrıca Beden Kitle indeksinde artış ile genomik kararsızlık arasında ilişki olduğu tespit edilmiştir. Sunulan çalışmada aşırı kilolu bireylerin muhtemel genotoksik hasarının araştırılması amaçlanmış olup bukkal epitel hücre örneklerinde Mikroçekirdek deneyi kullanılarak olası genotoksik hasar düzeyi hesaplanmıştır.
Yöntem: Sunulan çalışmada 18 yaşından büyük aşırı kilolu ya da normal kiloya sahip bireylerin olası DNA hasarı Bukkal Mikroçekirdek deneyi ile analiz edilmiştir. Aşırı kiloya sahip kişilere ait olası DNA hasar düzeyi sonuçları kontrol grubunu oluşturan normal kilolu kişilerin sonuçları ile SPSS analiz programı kullanılarak istatistiksel olarak karşılaştırılmıştır.
Bulgular: Sunulan araştırmaya yaş ortalaması 29.4±7.91 olan 25 kadın ve yaş ortalaması 38.21±10.47 olan 33 erkek toplamda 58 sayıda gönüllü; katılmıştır. Araştırmaya katılan bireylerin %39.70’i normal, % 60.30’u aşırı kiloludur. DNA hasarının göstergesi olan mikroçekirdek değeri tüm bireylerde ortalama 1.25±2.01 değerinde olup, aşırı kilolu bireylerin 37.2%’sında bu değer ortalamanın üzerindeyken, normal kilolu bireylerin %8.70’i ortalamanın üzerinde mikroçekirdek değerine sahip bireylerden oluşturmaktadır. Aşırı kilolu kişilerin mikroçekirdek değeri ortalama 1.68±2.41 olarak bulunmuştur. Bu değer normal kiloya sahip bireylerin bukkal mikroçekirdek sonuçları (0.60±0.89) ile karşılaştırıldığında istatistiksel olarak anlamlı derecede fark bulunmuştur (P<0.05).
Sonuç: Çalışma sonuçlarımıza göre beden kitle indeksinde artış ile DNA hasarı arasında anlamlı fark bulunmuştur (P=0.045). Sunulan çalışma Türkiye’deki yetişkin bireylerde aşırı kiloluluk ve DNA hasar düzeyinin değerlendirildiği ilk çalışma olma özelliğindedir. Gelecekte obeziteye ya da metabolik sendroma sahip kişilerde DNA hasar düzeyinin genotoksisite testleriyle araştırılacağı yeni çalışmaların yapılması önerilmektedir.
