Statin use in the group more than doubled, to 16.5 per cent in 2010 from 7.5 per cent in 1999. As expected, levels of LDL (bad cholesterol) and total cholesterol both declined more in statin users than in those not taking the drugs.
But daily calorie intake among statin users increased by 9 per cent over the period, and fat consumption by 14.4 per cent, while in non-users there were no significant changes in either measure.
Body mass index increased in statin users by 1.3, compared with an increase of 0.4 in non-users. The effect persisted even after controlling for age, race, education and diagnoses of diabetes and high cholesterol.
