Despite an increasing number of online programs to promote physical activity, they have rarely been evaluated for their effects on cardiovascular symptoms of racial/ethnic minority women at midlife. This study aimed to determine the preliminary efficacy of a newly developed online program for physical activity promotion on cardiovascular symptoms of Asian American midlife women. This study was a pilot repeated-measures randomized controlled trial (pretest/posttest) among 26 Asian American midlife women. The variables were measured using multiple instruments on background features, physical activity, and cardiovascular symptoms at three points of time (baseline, after 1 month, and after 3 months). Linear mixed models were used to analyze the data. The prevalence and severity of cardiovascular symptoms did not show a statistically significant group-time interaction. However, the increase in lifestyle physical activity over time was significant only among the intervention group ([DELTA] = 0.49, P = .016). The results supported the program's preliminary efficacy on lifestyle physical activity for Asian American women at midlife, but not on cardiovascular symptoms.
