Key result
Overweight and obesity in youth linked to ~6-fold higher rate of elevated blood pressure.
Why the study?
Cardiovascular risk factors in overweight or obese children and adolescents in Germany, Austria, and Switzerland and their relationship to BMI category were not well characterized.
Cross-Sectional (n=77,323)
Yes
PURPOSE: To assess cardiovascular risk factors in overweight or obese children and adolescents in Germany, Austria and Switzerland and to investigate the relationship to BMI category. METHODS: Data of 63,025 overweight or obese patients (APV population) were compared to normal-weight subjects from a representative study on health status of 14,298 children and adolescents in Germany (KiGGS survey). The weight status was assessed by BMI, and BMI-SDS values were cal-culated using national reference data. RESULTS: In normal-weight KiGGS subjects, mean BMI was 17.3 ± 2.5 (BMI-SDS -0.1 ± 0.8). In the overweight or obese APV population, mean BMI was 30.2 ± 5.6 (BMI-SDS 2.5 ± 0.6). In normal-weight subjects blood pressure, total cholesterol, LDL-cholesterol, and triglycerides were elevated in 6.1, 8.6, 7.0 and 3.0%, respectively, and HDL-cholesterol was reduced in 3.0%, whereas in overweight/obese subjects the percentages of abnormal values were 35.3, 13.8, 14.5, 13.6, and 10.1%, respectively. CONCLUSIONS: Cardiovascular risk is increased in obese children and adolescents. There is a strong need to monitor blood pressure and serum lipids in this group of patients. Our results emphasize the importance of prevention of obesity in order to reduce cardiovascular risk.

Flechtner‐Mors et al. (2011) conducted a cross-sectional in Overweight and obesity (n=77,323). Overweight or obesity vs. Normal weight was evaluated on Elevated blood pressure. Overweight and obesity in children and adolescents were associated with a higher prevalence of elevated blood pressure (35.3% vs 6.1%) and other cardiovascular risk factors compared to normal weight.
