Effects of health promoting education program for Korean middle-aged women.

Participants were recruited by convenience sampling from a community centre in Seoul, so the findings may not apply to other regions or settings. The study was not randomised, and the control group received no program, so attention, expectations, or unmeasured baseline differences may explain some of the effect. Outcomes were self-reported questionnaires, and the paper did not identify a single primary outcome, so the positive findings are not protected against chance. The only post-test was immediately after the six-week program, so it is unknown whether the changes lasted. The reported religion percentages in the results text do not match the general characteristics table, which raises a possible reporting inconsistency.

The authors declared no conflict of interest.

Do not conclude that education alone caused the improvements. The intervention combined lectures, books, audio-visual materials, models, exhibitions, and group discussion, so the contribution of any single component cannot be separated. The study also used a non-randomised convenience sample, so attention or baseline differences cannot be ruled out.
