Gender effect on various standing ability in elderly Thai population
Main Article Content
Standing balance is important for daily living activities, especially in the aging population. The objective of this study is to determine the gender effects on standing ability in the elderly Thai population. A cross-sectional study was designed for Thais 60–80 years old (n=109). Eight standing balance tests consisted of bipedal on both a stable and foam surface and unipedal standing on the left and right legs. All tests were performed both with eyes open and with eyes closed. Sway velocity was significantly higher in women compared with men in Right leg standing with eye open condition (p=0.017). Differences between left and right leg were found in men during standing eyes-open tests (p=0.00). ANCOVA found no relationship between demographic data (BMI, weight, and height) and sway velocity in either men or women. Men presented better stability indicated by lower sway velocity on right leg standing balance tests. Balance exercises for the elderly should be implemented for both genders, especially for elderly women. In conclusion, gender differences were presented in one leg standing condition but no relationship between BMI and sway velocity was found in Thai elderly population.
