[Epidemiology of infectious diseases--analysis of an increase of infectious hepatitis in Hamburg]. / Infektionsepidemiologie--Analyse der Zunahme der infektiösen Hepatitis in Hamburg.

In Hamburg, the incidence of reported cases of infectious hepatitis more than doubled from 1990 to 1991. The increase refers to hepatitis A, B and other forms of hepatitis. The seven public health offices and the local ministry for health, works and social affairs in Hamburg have analysed the development in a computer-based retrospective study comparing the 1990 and 1991 data. The predominantly affected age group of hepatitis A shifted from childhood to young adulthood. The importance of travelling to acquire hepatitis A was less than expected. In all forms of hepatitis the large number of IV-drug users and prisoners was striking.

Federal Republic of Germany: perspectives in school health.

In the Federal Republic of Germany, responsibilities for health and education are held by the 11 German states. Particularly in the health system, a number of tasks are delegated to private organizations under governmental control. In this review, general characteristics of both the public health and education systems are delineated. An overview of school health programs, including instruction, health services, environment, and school-community relations, and school-based research, also are presented.

Low-level cigarette smoking and longitudinal change in serum cholesterol among adolescents. The Berlin-Bremen Study.

The current study was conducted to determine if smokers and nonsmokers differ in serum concentrations of high-density lipoprotein cholesterol (HDL-C) before smoking initiation and if a decline in HDL-C levels could be detected among adolescents during the first two years of smoking. Changes in HDL-C levels and smoking were observed longitudinally in 1983, 1984, and 1985 among 691 seventh and eighth graders (age range, 12 to 14 years) from two German cities; 82% were nonsmokers at baseline. For these baseline nonsmokers, no differences in baseline HDL-C concentrations were found between those who became smokers and those who remained nonsmokers. In contrast, those who became light (one to 39 cigarettes per week) or moderate (greater than or equal to 40 cigarettes per week) smokers by one or two years after the initial examination evidenced lower mean HDL-C concentrations relative to persistent nonsmokers at follow-up, constituting a decrement of -0.016 mmol/L [SE = .035] (-0.6 mg/dL) [SE = 1.4] for light smokers and -0.114 mmol/L [SE = .064] (-4.4 mg/dL) [SE = 2.5] for moderate smokers. These findings suggest that short-term exposure to cigarette smoke at low levels may have atherogenic consequences.
