Risky leisure noise exposure during the transition to adulthood and the impact of major life events - results of the OHRKAN cohort study.

Objective: To investigate the influence of four major life events (leaving home, full-time employment, married/cohabiting, parenthood) and socio-demographic variables on risky total leisure noise (TLN) during transition to adulthood with a special focus on visiting discotheques and listening to portable listening devices (PLDs).

Design: Longitudinal analysis of the OHRKAN cohort. Risky TLN covering 22 activities was defined as exceeding 85 dB(A) averaged over a 40-hour week.

Risky listening behaviour to music via headphones and its determinants - 7.5 years OHRKAN cohort study.

Objective: To examine risky leisure noise exposure from listening to music via headphones and to identify potential determinants with special focus on portable listening devices (PLDs) among adolescents over a period of 7.5-years.

Design: Data were collected by questionnaires at four equidistant time points (O1-O4).

Ten-year results of leisure noise exposure among adolescents and young adults-findings from the OHRKAN cohort study.

Objective: To observe total leisure noise (TLN) exposure and to investigate determinants of risky TLN exposure among adolescents and young adults over a ten-year observation period.

Design: OHRKAN is a longitudinal study with five equidistantly distributed questionnaires (waves) over ten years. Risky TLN exposure was defined as exceeding ≥85dB(A) averaged over 40h per week.
