Abstract

It is important to determine specific Body Mass Index (BMI) cut-off points on country and sex bases since there are anthropometric differences. Therefore, a study was proposed to find out specific body mass index [BMI-TR (kg/m2)] cut-off points for Turkish young adults. BMI-TR was compared with the classifications of the World Health Organization’s Index (BMI-WHO) and Asia-Pacific Index (BMI-AP). In this research a study enclosing the weight and height measurements of 196 cases (97 Male, 99 Female, age average 22.5 years) were examined. The recorded total data were calculated according to BMI-WHO and BMI-AP, subsequently the same data were computed according to Empirical Rule to find out the cut-off points of the BMI-TR and also specific BMI-TR cut-off points for males and females. The data were compared for both BMI-WHO and BMI-AP categorizations and showed inconsistent results. Therefore, BMI-TR was calculated and classified according to sex. In this study, Turkish specific BMI results for BMI-TR Males and BMI-TR Females revealed that the percentage of females showing normal BMI was higher (78.8%), than males (70.1%), and being underweight (14.4 % for males, 10.1 % for females) was more serious than being obese (5.2% for males, 4.0 % for females) in the “young adult” age group. BMI calculations should include age groups, sex and adjustment of height decrease for elderly on country basis.

Thanks

The authors would like to extend their acknowledgements to the subjects for their volunteer cooperation during the measurements and to Prof. Dr. Mehmet Yaşar İşcan, may his soul rest in peace, for his teachings on collecting anthropometric data and advise to realise this study. We are delighted to find an intuitive recognition of body mass in the dialogue of William Shakespeare’s play in “The Comedy of Errors”: Antipholus of Syracuse: “Then she bears some breadth?” Dromio of Syracuse: “No longer from head to foot than from hip to hip. She is spherical, like a globe. I could find out countries in her”. - William Shakespeare (1564-1616) The Complete Comedies

Dünya Sağlık Örgütü ve Asya-Pasifik endeksleri ile karşılaştırılan Türkiye beden kitle endisi kesim noktaları için öneri

Abstract

Beden Kitle Endisi (BKE) hesaplamalarında, toplumlararası antropometrik farklılıklar nedeniyle ülke ve cinsiyet bazında belirli kesim noktalarının belirlenmesi önemlidir. Bu sebeple bu araştırmada, Türk genç yetişkinleri için spesifik beden kitle endisi [TR-BKE (kg/m2)] kesim noktalarını saptamak için bir çalışma yürütülmüştür. TR-BKE, Dünya Sağlık Örgütü endisi (DSÖ-BKE) ve Asya-Pasifik endisi (AP-BKE) sınıflandırmaları ile karşılaştırılmıştır. Bu araştırmada 196 olgunun (97 Erkek, 99 Kadın, yaş ortalaması 22,5 yıl) ağırlık ve boy ölçümlerini içeren verileri incelenmiştir. DSÖ-BKE ve AP-BKE’ye göre hesaplanan BKE sınıflandırılmıştır. Bu verilere istatistiksel Ampirik Kural uygulanarak TR-BKE ve ayrıca erkekler ve kadınlar için TR-BKE erkek ve TR-BKE kadın endisi kesim noktaları bulunmuştur. Veriler hem DSÖ-BKE hem de AP-BKE’ye göre sınıflandırıldığında sonuçlar tutarsızlık göstermiştir. Bu nedenle TR-BKE hesaplanarak cinsiyete göre belirlenmiştir. Bu çalışmada, Türkiye’ye özgü BKE kesim noktaları ve aynı zamanda erkekler ve kadınlar için ayrı BKE kesim noktaları bulunmuştur. Buna göre “genç erişkin” yaş grubunda erkeklerin %70,1’i kadınlarda ise %78,8’i normal sınıflamaya, erkeklerin %14,4’ü, kadınların ise %10,1’i zayıf gruba girerken, erkeklerin %5,2’i ve kadınların %4,0’ı obez gruba girmektedir. Bu sonuç Türk genç erişkinler için obez olma durumuna kıyasla, zayıf olma durumunun daha ciddi olduğunu ortaya çıkartmıştır. BKE hesaplamalarında araştırılan ülkeye özgün olarak; yaş gruplarının, cinsiyetin ve bu hesaplamalarda yaşlanmaya bağlı boy kısalma miktarının göz önüne alınması önerilmiştir.
