Scientists at University College London looked at how likely people were to quit smoking, start being active, or lose weight in relation to what their partner did.
They found that people are more successful in taking up healthy habits if their partner makes positive changes too.
Among women who smoked, 50 per cent managed to quit if their partner gave up smoking too at the same time, compared with 17 per cent of women whose partners were already non-smokers, and eight per cent of those whose partners were regular smokers.
The research looked at 3,722 couples, either married or living together and over the age of 50, who were taking part in the English Longitudinal Study of Ageing (ELSA).
"Unhealthy lifestyles are a leading cause of death from chronic disease worldwide. The key lifestyle risks are smoking, excess weight, physical inactivity, poor diet, and alcohol consumption," said Professor Jane Wardle, director of Cancer Research UK's Health Behaviour Research Centre at UCL and one of the study authors.
The research was published in JAMA Internal Medicine.
