Taking Medicine Regularly (Even Placebo) Lowers
Death Risk
June 30, 2006 - People who take their medicine
regularly, even dummy placebo medicine, have a lower risk of death than
those with poor adherence, finds a study in this week’s British Medical
Journal (BMJ).This intriguing finding supports the concept of the
“healthy adherer” effect, whereby adherence to drug treatment may be a
marker for overall healthy behavior, say the authors.
They analyzed 21 studies involving over 46,000
participants. For those with good adherence to drug therapy or placebo,
the risk of mortality was about half that of participants with poor
adherence.
Possible reasons for this effect are that
participants with good adherence to study drugs (even placebo) may also
have good adherence to other healthy behaviors, which could
independently affect the risk of mortality, explain the authors.
Conversely, participants with poor adherence may have consciously chosen
to use a lower dosage or have other conditions, such as depression, that
affect adherence.
“Our findings support the tenet that good adherence
to drug therapy is associated with positive health outcomes,” they
write.
“Moreover, the observed association between good
adherence to placebo and lower mortality also supports the existence of
the healthy adherer effect, whereby adherence to drug therapy may be a
surrogate marker for overall healthy behavior.”
In an accompanying commentary, US researcher Betty
Chewning suggests that it is quite possible that people who adhere to
healthy lifestyles also tend to take care of themselves by greater
adherence to prescribed treatments.
She points to research showing that healing may lie
not in the treatment but rather in patients’ emotional and cognitive
processes of “feeling cared for” and “caring for oneself.” And she
suggests that practice based on these hypotheses “could yield extra
value in treatment regimens that patients agree to, believe in, and will
sustain over time.”
