Abstract

A pilot study has been conducted to prepare for an epidemiological study into the effects of vibration on tractor drivers. The reason for the study is that, despite a large volume of existing data on health and vibration (over 43,000 exposed workers having been studied) there is still no good basis for estimating dose-response relationships between vibration and health. There have been three main difficulties: - - Many studies have not measured vibration, or have not measured it thoroughly enough.- - Confounding variables such as posture have not been entirely controlled for, because well-matched control groups do not exist.- - Health data have tended to be binary incidence data rather than continuous scale data, reducing the sensitivity of the studies. The pilot study has produced procedures to overcome these difficulties.
