IT'S a tricky question for women in stable relationships. Do you stay on the pill, even though prolonged use slightly raises the risk of heart disease and other conditions, or do you switch to a less effective contraceptive? Now it seems there is an alternative.
Anneli Pouta at the University of Oulu, Finland, and colleagues studied 2814 women, all aged 31, taking the combined pill, no hormonal contraceptive or fitted with an intrauterine device (IUD) that releases small doses of progesterone into the womb.
Women on the combined pill had higher blood pressure, cholesterol and insulin levels than those who were not. Women fitted with IUDs, which are more than 99 per cent effective at preventing pregnancy, had none of these problems, probably because hormones are released locally rather than into the general circulation, Pouta says.
So, for young women the pill is fine. After the age of 40 the IUD seems the better choice.
