Adherence to a Heart-Healthy Lifestyle: Testing of the Information-Motivation-Behavioral Skills Model.
Yura Shin, Jina Choo, Songwhi Noh
PMID 40934336WHAT IT FOUND
Heart-healthy motivation was associated with adherence to a heart-healthy lifestyle.
Diet and exercise confidence also helped. Heart facts alone were not linked to adherence after motivation and confidence were considered, and were linked to lower exercise confidence.
Key findings
01Heart-healthy intrinsic motivation was associated with adherence both directly and through diet and exercise self-efficacy.
02Self-efficacy for diet and exercise was associated with adherence.
03In the final model, heart-healthy information was associated with higher diet self-efficacy but lower exercise self-efficacy, and not with adherence.

What it does not show
The cross-sectional design cannot show that motivation or self-efficacy caused better adherence. All data were self-reported, so responses may be biased. The sample was limited to South Korean adults aged 19 to 64 who could take online surveys, so it may not apply to older adults, people without internet access, or other countries. People with cardiovascular disease, mental disorders, physical disabilities, or cognitive impairment were excluded, so findings do not apply to those groups. Only 618 of 2910 eligible panel members completed the survey, a response rate of 21.2%, so participants may differ from nonparticipants.
Declared interests
The work was supported by the National Research Foundation of Korea and Korea University. The authors declared no conflicts of interest.
The easy way to misread this
Do not conclude that counselling on motivation or self-efficacy will improve heart-healthy adherence. This study measured associations at one time point and did not test an intervention.
