Smokers 'less likely to need hip replacement surgery'

11th July 2011

A surprising new study has suggested that smoking males are less likely to need hip replacement surgery.

The research, which was conducted at the University of Adelaide in Australia and detailed in the journal Arthritis & Rheumatism, found that while men who are overweight increase their risk of needing hip or knee surgeries, smokers were less likely to require such procedures.

Men who have smoked for 48 years or more were up to 51 per cent less likely to need joint replacement surgery than those who had never smoked.

Commenting, George Mnatzaganian, a PhD student, said: "Our study is the first to demonstrate a strong inverse correlation between smoking duration and risk of total joint replacement. The independent inverse associations of smoking with risk of total joint replacement were evident also after adjusting for major confounders and after accounting for the competing mortality risk in this elderly cohort of men."

He added that further investigation is needed.

Figures show that around ten million UK adults smoke cigarettes.
