The combined use of cholesterol-lowering drugs and cholesterol-lowering bread spreads: health behavior data from Finland.
BACKGROUND
Cholesterol-lowering drugs may metabolically interact with cholesterol-lowering bread spreads. This study analyses the prevalence of use of drugs, bread spreads or the combination of both in people aware of their high/elevated cholesterol level, and compares users of the three therapies on health behavior and demographics.


METHODS
Participants (9581, 25-74 years) from The National FINRISK 2002 Study filled out a questionnaire on demographics and health (related) issues. Blood samples, blood pressure, body weight and height were measured.


RESULTS
Of those who reported to have a high cholesterol level (31% of the study population), 19% used cholesterol-lowering drugs, 11% used cholesterol-lowering bread spreads and 5% combined both therapies. On a population level, only 1% jointly used a drug and bread spread therapy. The combination was used by especially highly educated people and those having a healthy diet.


CONCLUSIONS
Combining a cholesterol-lowering drug with a bread spread regimen is relatively rare, even among those being aware of their high cholesterol levels. The combined usage was most frequent among 'the better off'. Public health risks of a metabolic interaction between both therapies may not be of major importance yet, but future follow-up is recommended.
