The Sydney Airport Health Study (SAHS) surveyed 1015 individuals exposed to aircraft noise near Sydney airport in 1994. Aircraft noise is regarded as a potent stressor. Individuals of Types 1 and 2 personality on the Grossarth- Maticek personality-stress inventory (GMPSI) were found to be more reactive to noise than other types. The current study investigated whether personality type could predict long term health outcomes amongst these individuals, as observed in earlier studies of Grossarth-Maticek. In contrast to these early studies, our subjects were known to have experienced a salient stressor. Names and information from the original SAHS respondents were matched to the Australian National Death Index in order to establish who had died and of what cause. Relationships between cause of death and a range of variables collected in the original study (GMPSI scores, other psychological variables, ratings of noise induced annoyance, general health status) was assessed. Discussion will focus on the implications of these results for the Grossarth-Maticek theory. The theory proposes that when exposed to stress, unhealthy types (Types 1 and 2) as identified by the GMPSI, are more vulnerable to cancer and heart disease respectively than those of healthy types (Type 4).
