生活習慣真的很難改，影響療效甚鉅
而且「真正需要在生活上改變的人」，是最喜歡把罪過推給基因的那群人...

Poor Health? Easier for Some to Blame Bad Genes Than Change Lifestyle
ScienceDaily (June 10, 2010) — Does knowing that genes are partly
responsible for your health condition mean you are less likely to be
motivated to find out about the benefits of behavioral changes? According to
Dr. Suzanne O’Neill from the National Human Genome Research
Institute/National Institutes of Health, and her colleagues, people on the
whole are still interested in how health habits affect disease risk. However,
those with the greatest need to change their behaviors are more likely to
favor genetic explanations for their diseases and the more behavioral risk
factors they have, the less likely they are to be interested in behavior
change information.
The study is published online in Springer’s journal Annals of Behavioral
Medicine.
The completion of the Human Genome Project has led to increased availability
of genetic risk information linking gene variants to a number of common
health conditions. There is some concern that this genetic risk information
might prompt some individuals to give genetic causation undue importance
while downplaying the contribution of well-known behavioral and environmental
factors, leading to reduced motivation to make behavioral changes. This
potential misinterpretation of genetic information may undermine public
health efforts to promote the behavioral changes needed to prevent disease.In
order to identify the link between family history, behavioral risks and
causal attributions for diseases and the perceived value of pursuing
information emphasizing health habits or genes, the authors asked a total of
1,959 healthy American adults to complete a survey.
The survey assessed the participants’ behavioral risk factors (physical
activity, dietary habits, smoking, alcohol consumption, sun exposure,
multivitamin use and body mass index), family history, causal attributions
for eight largely preventable diseases (diabetes, osteoporosis, heart
disease, high cholesterol, hypertension, lung, colon and skin cancers), and
their preferences for one type of health information over another.They found
that the majority of participants recognized that health behaviors were more
likely to cause ill-health than genetics.
On the whole, they were more interested in behavioral health information than
in genetic information to understand what affects their chances of getting
certain conditions. However, as the number of behavioral risk factors
increased, inclination to favor genetic explanations also increased.The
authors conclude: “Our findings highlight that, although most did not
over-ascribe common health conditions to genetics or hold defensively biased
causal attributions that would inhibit needed behavior change, those with the
greatest need for behavior change are at most risk for responding defensively
and devaluing behavior change information. One possible explanation suggested
by the authors is that behaviorally at-risk participants may have prior
experience seeking and applying standard behavioral advice without success.
As a result these individuals may see less value in this information.
