Longitudinal Health

The Norwegian Longitudinal Health Behaviour Study

Principal Investigator: Bente Wold

The main aims of the study are to examine tracking of health behaviours and subjective health during this life period, and to analyse how social influence processes during adolescence may predict subjective health and lifestyle in early adulthood.

This unique study started in 1990 among approximately 900 thirteen-year-olds and their parents in Hordaland county. Surveys among the adolescents have been conducted 1990, 1991, 1992, 1993, 1995, 1996, 1998, 2000 and 2007. Parents have participated in 1990, 1993 and 1996.

The response rates have been reasonably high during all data collections. At the previous data collection in 2007 questionnaires were filled in by 536 respondents. The final data collection among parents in 1996 included 1163 filled-in questionnaires.
