Many people including drivers have OSA and don’t realise it. Obstructive Sleep apnoea is more common in men aged 30 - 65 years, though it can occur in all age groups. It affects an estimated 4% of males and 2% of females worldwide.

In South Africa it is thought to be considerably higher in specific groups and occupations were the consequences can be fatal or lead to serious injury if left undiagnosed and treated.

Sigma Sleep Diagnostics is currently screening freight company drivers to determine the prevalence of OSA amongst professional drivers companies. A number of the largest South African freight companies have commissioned these studies. If you would like more information or details on how to take part in the screening programme, to reduce your personal or corporate risk please contact us.
