Prevalence of obesity and overweight in male 18-year-olds in Austria from 2006 to 2010: an update
BACKGROUND: Obesity is one of the most important health-related problems in the 21st century. Data on its respective prevalence in Austria remain scarce. The aim of this study was to determine the current trends of overweight and obesity classes in a subset of 18-years-old male subjects and its potential impact on future bariatric surgery demand. METHODS: Data from compulsory military conscription examinations in male 18-year-olds from 2006 to 2010 were obtained from the Federal Ministry of Defense database. Measurements of height, weight and subsequent BMI calculations in 211,221 conscripts were subdivided into yearly cohorts. Overweight was defined as BMI 25.0–29.9 kg/m2, obesity grade I as BMI 30.0–34.9 kg/m2 and obesity grade II+ as BMI ≥ 35.0 kg/m2. Furthermore, the number of conscripts who became ineligible for military service caused by their obesity diagnosis (ICD-10 E66.x) was recorded. RESULTS: Mean BMI increased from 23.16 ± 3.90 kg/m2 (2006) to 23.41 ± 3.98 kg/m2 (2010; p < 0.001). Overweight, obesity grade I and obesity grade II+ increased from 18.77%, 5.36%, 2.12% in 2006 to 20.57%, 5.96%, 2.40% in 2010, respectively. Furthermore, an increasing gradient of overweight, obesity grade I and II+ from west to east was found. In 2006 0.19% and in 2010 0.48% of all conscripts were considered ineligible military service. CONCLUSIONS: BMI remains increasing in Austrian adolescents. Obesity stage II+ shows a continuous increase that will lead to a higher demand for bariatric procedures in the future.
