PREVALENCE AND EPIDERMIOLOGICAL RISK FACTORS OF OBESITY IN TURKEY
Introduction:
World Health Organization (WHO) declared that obesity is a chronic disease prevalent in both developed and developing countries, and its impact is so diverse and extreme that it should now be regarded as one of the greatest neglected public health problems of our time with an impact on health which may will prove to be as great as of smoking. Obesity is a complex multi-factorial chronic disease that develops from an interaction of genotype and environment. Our understanding of how and why obesity develops is incomplete, but involves the integration of social, behavioral, cultural, physiological, metabolic and genetic factors. The signs and symptoms of obesity include an excess accumulation of adipose tissue and from the pioneer studies like Framingham and Nurses Health Study; it's known that, there is a 'U or J' shape relationship between mortality and fat weight. While low body mass index (BMI) is associated with high mortality rates principally from pulmonary and gastrointestinal diseases, in contrast high BMI levels have an impact on high risk of mortality from cardiovascular disease (CVD), diabetes mellitus (DM), hypertension, dislipidemia, stroke, and cancer.

Both obesity prevalence and its epidemiological risk factors like physical activity levels, smoking, and alcohol consumption are not well studied in Turkish population. In two major studies; TEKHARF (Turkish Adults Hearth Disease and Risk Factors Study) and TURDEP (Turkish Diabetes Epidemiology Study) the obesity is studied as an independent risk factor for CVD and DM nationwide.

In TURDEP study the obesity prevalence (BMI>29.9 kg/m²) is found 22% while in TEKHARF study it is found 21.1% among males and 43.0% in females.

According to the results of TURDEP study, male subjects had mean BMI, waist hip ratio (WHR) and waist circumference (WC) of 25.47±4.58 kg/m², 0.88±0.10, 90.03±13.86 cm and females had 27.45±5.76 kg/m², 0.81±0.09, 87.20±14.61 cm respectively. In TEKHARF study among male subjects mean BMI, WHR, WC are found 26.8±3.9 kg/m², 0.93±0.07, 91.8±10.6 cm and in females 29.2±5.3 kg/m², 0.86±0.70, 89.4±12.1 cm respectively. In TEKHARF study BMI was found as an independent risk factor for CVD in men and the cardiovascular event risk were found to be increasing 9% in every 1 kg/m² BMI increment. Also in TURDEP study it was found that prevalence of DM and impaired glucose tolerance increased with increment in BMI, WHR or WC.

These results indicates the importance of monitoring the obesity nationwide and in different regions of the Turkey, because there is a great difference of the socio-economical status between the populations who live in different parts of the country. In this cross-sectional study carried out in Edirne, Turkey it was aimed to find out the prevalence of obesity indicated as BMI=30 kg/m², and to identify epidemiological risk factors.
