- Developmental studies of antisocial behavior (ASB) have found two subgroups of behaviors, roughly described as aggressive and nonaggressive ASB. Theoretical accounts predict that aggressive ASB, which shows greater stability, should have high heritability. In contrast, nonaggressive ASB is very common in adolescence, shows less continuity, and should be influenced both by genes and shared environment. This study explored the genetic and environmental influences on aggressive and nonaggressive ASB in over 1,000 twin pairs aged 8–9 years and again at 13–14 years. Threshold models were fit to the data to incorporate the skew. In childhood, aggressive ASB was highly heritable and showed little influence of shared environment, whereas nonaggressive ASB was significantly influenced both by genes and shared environment. In adolescence, both variables were influenced both by genes and shared environment. The continuity in aggressive antisocial behavior symptoms from childhood to adolescence was largely mediated by genetic influences, whereas continuity in nonaggressive antisocial behavior was mediated both by the shared environment and genetic influences. These data are in agreement with the hypothesis that aggressive ASB is a stable heritable trait as compared to nonaggressive behavior, which is more strongly influenced by the environment and shows less genetic stability over time.

- OBJECTIVES: Previous studies have shown a high prevalence of users of complementary and alternative medicine (CAM) remedies in Anglo-Saxon countries. We have explored the use of CAM remedies in Sweden, its distribution in different population groups and time trends during the years 1990-99. DESIGN AND SUBJECTS: Within the framework of the population-based northern Sweden Multinational Monitoring of Trends and Determinants of Cardiovascular Disease (MONICA) Project, randomly selected 25-74-year-old participants in risk factor surveys performed in 1990, 1994 and 1999 responded to questions about their use of CAM remedies. The participation rate was 72%. RESULTS: Amongst 5794 respondents in the 1999 survey, 30.5% reported that they had taken a CAM product (vitamins, minerals or biological CAM remedy) in the preceding 2 weeks. Vitamins/minerals only had been taken by 11.7% and other CAM remedies (dominated by fish oil, ginseng and Q10) with or without vitamins/minerals by 18.8%. Use of CAM remedies was more frequent in women than in men and more frequent in people with high than with low level of education. The prevalence was unrelated to a history of severe cardiovascular disease or diabetes but significantly more common in subjects with poor self-perceived health, particularly so in women. During 1990-99, the use of CAM remedies increased, more in women than in men. CONCLUSIONS: The prevalence of CAM remedy use (other than vitamins and minerals) is high in Sweden. It has been increasing during the 1990s. Its use is particularly common in women, well-educated people and in those with poor self-perceived health.
