Effect of Square Dance to Reduce Risk for Coronary Heart Diseases among Older Adults in China: a Randomized Controlled Trial Purpose: Square dance is commonly practiced in the Chinese mainland as a kind of social events to enhance quality of community life and personal well-being. It is also one form of physical activities and therefore might improve health and prevent diseases. However, evidence on its health effects is scarce. The present intervention study was a randomized controlled trial (RCT) and aimed to evaluate effectiveness of square dance to reduce risk for coronary heart disease (CHD) among Chinese elderly. Methods: Participants were recruited from four communities in an eastern city in China and then randomly assigned into intervention and "wait-list" control groups. The participants in the intervention group attended specially designed 1-hour square dance sessions five times a week for 12 consecutive weeks, whilst those in the "wait-list" control were asked to keep their current physical activity habits during the same time period. Outcomes consisted of important indexes of CHD, including body weight, waist circumference, body mass index (BMI), basal heart rate, blood pressure, and standing balance ability, measured at Weeks 0, 5, 9, and 13 (four times). Repeated measures ANOVA (group and time as two factors, gender, age, height as covariates) and intention-to-treat analysis were adopted. Results: A total of 150 adults were invited, 60 met our selection criteria and participated in the study (age: 40-60 years, female=40). Of them, 34 were randomly assigned in the intervention group and the other 26 in control, and all completed the study. There were no significant between-group differences in all measures at baseline. Participants undertaking square dance had significant decrease on weight, waist circumference and BMI, and significant increase on balance ability. However, changes in basal heart rate and blood pressure were not significant between the two groups. Conclusion: Square dance is effective to reduce body weightrelated risk factors of CHD, suggesting the potential of square dance in the prevention of CHD among older adults. Further studies are warranted to confirm the results and examine its long-term effect. Copyright © 2018 ISBNPA.
