Abstrakt: Aim: A high cardio respiratory fitness level (CRF) has been shown to be associated with cardiovascular disease risk factors. It is the objective of these analyses to compare risk factors for low CRF between girls and boys and to investigate whether the impact of social inequality on CRF can fully be explained by the known risk factors for low CRF. Subjects and methods: German Health Interview and Examination Survey for Children and Adolescents (KiGGS) was a cross-sectional population representative study; the present analyses include 5,908 participants (11-17 years) in whom CRF was measured by a submaximal cycle ergometer test. The odds ratios (OR) from sex stratified, age-adjusted logistic regression models analysing the chance of low CRF were calculated and a multivariate logistic regression model was built. Results: Multivariate models showed that low CRF was associated with high body fat (girls: OR 3.53; 95 % Confidence Interval (CI) 2.71-4.59; boys OR 6.69; 95 % CI 3.86-11.6), physical inactivity (girls: OR 3.09; 95 % CI 2.12-5.52; boys OR 4.25; 95 % CI 2.53-7.15) and extensive media use. Beyond these factors, adjusted analyses showed that low socio-economic status in boys and two-sided migration background in girls were associated with low CRF. Conclusion: CRF in German youths shows social inequality and cultural and sex differences which cannot fully be explained by the known risk factors for low CRF. Cardiovascular prevention should consider social inequality and should involve measures against overweight, lack of physical activity and abundance of sedentary activities. [ABSTRACT FROM AUTHOR]
