[Screening for risk factors in agricultural schools of 5 Austrian federal counties ].

While screening activities have already been performed in a wide range in adults in Austria, extensive investigations in children and juveniles have so far only been done in a very limited number. In 1094 out of 1732 juveniles attending agricultural schools all lipid parameters were fully documented and thus could be evaluated. On an average, the total cholesterol (169 mg/dl) was too high; the worst findings for lipid parameters cholesterol, HDL-cholesterol, triglycerides, apolipoprotein-A1 were found in pupils of Burgenland. The cholesterol/HDL-cholesterol ratio in Burgenland was significantly (p < 0.01) higher than in Lower Austria. Female participants had a higher total cholesterol, HDL-cholesterol, and apolipoprotein-A1, but lower triglycerides and also lower blood pressure. Juveniles with a positive family history showed lower total cholesterol, but higher triglycerides as well as HDL-cholesterol. In heavy smokers, but also in occasional smokers, a lower total cholesterol, but decreased HDL-cholesterol and apolipoprotein-A1 and increased triglycerides were found. These findings underline the high prevalence of hypercholesterolemia in juveniles justifying screening activities and possibly therapeutic intervention at this young age.
