Prevalencia nadhmotnosti a obezity v náhodne vybratej skupine mladých žien a ich klinicko-somatické parametre

Prevalence of the Overweigt and Obesity in the Random Selected Group of Young Females and Their Clinical-somatic Parameters

Background.
Obesity is serious health-nutritional problem and its incidence moves into younger age. The aim of the study was to evaluate clinical - somatic parameters of the health-nutritional state in the random selected group of young females. Prevalence of the overweight and obesity were studied and risk of their reciprocal relations of the clinical - somatic parameters was evaluated. 

Methods and Results.
We evaluated 161 females between the ages of 20–25 years (average age 21,6±1,1 years). The body fat content was measured using the method of bioelectrical impedance analyse and Bodystat Quadscan 4000 (Bodystat Ltd, Doubles, Isle of Man, UK). Body mass index, index of centrality, waist to height ratio, ideal body weight and difference between the actual and ideal body weight was calculated on the basis of measured values. Total cholesterol in the blood was measured by Reflotron Plus (Matsuka Co. LTD, Japan). The results showed that in the tested group of females 49,1 % body fat content had less than 20 % (group A), 47,8 % women had body fat content varying from 20 to 29 % (group B), and 3,1 % had fat content varying from 30–34 % (group C). The higher values almost of all evaluated parameters was confirmed (total cholesterol, body mass index, waist circumference, index of centrality, waist to height ratio and difference between the actual and ideal body weight) in groups with higher fat content (group B and C). In all groups significant differences were observed. According to circumference of waist and hip the android health risk had 3,1 % of women. The increased risk of metabolically complications of obesity had 5,6 % of women and high risk 1,2 % of women. The critical value of cholesterol had 8,1 % of investigated women. Accorging to the body mass index (D, E, F groups) had 90,1 % of females normal body weight (group D), 9,3 % of overweight (group E) and only 0,6 % obesity. With increasing value of body mass index were also increased values of all monitored parameters, between groups D and E was differences significant in six of eleven parameters (body weight, waist circumference, waist to hip ratio, waist to height ratio, difference between the actual and ideal body weight). 

Conclusions.
The increased cholesterol level is more frequent in women body with higher content of body fat. Groups with higher content of body fat have, except of body weight and body mass index, concurrently higher the waist circumference, waist to hip ratio, waist to height ratio and difference between the actual and ideal body weight.
