Obezitenin Tanımı, Epidemiyolojisi ve Klinik Değerlendirmesi

Obezit e, vücut ta aşırı yağ birikimidir. Ortalama vücut ağırlığına sahip erkeklerde vücut yağı %15-20, kadınlarda ise %25-30 arasındadır. Vüc ut y a ğ yüzdesini belirlemek kolay olmadığı için obezite, aşırı yağdan daha çok aşırı kilo olarak t anımlanmaktadır. Dünya Sağlık Örgüt ü (DSÖ), fazla kiloluluk ve obezit e t anımını beden kitle indeksine (BKİ = Ağırlık [kg] / Boy [m2]) dayanarak yapmaktadır. Artan obezite prevalansı t üm dün y a da büy ük bir sağlık problemidir

Definition of Obesity, Epidemiology and Clinical Evaluation

Obesity is excessive fat accumulation in the body. For men with average body weight , body fat is 15-20% and in women it is between 2 5 -3 0%. Because it is not easy to determine the body fat percentage, obesity is defined as overweight rather than excessive f at . Wo rld Heal th Organ isat ion (WHO) makes overweight and obesity definitions based on body mass index (BMI = Weight [kg] / Height [m2]). The increased prevalence of obesity is considered as a major health problem all over the world.
