Brief Summary:

Hong Kong, similar as other developed economic entities, has been faced big challenges from increasing medical burden and aged population. Based on the updated estimates of domestic health expenditure by Food and Health Bureau HKSAR, the total health expenditure amounted to HK$112,144 million in 2012/13 with increasing approximate 4 times than 1992/93. According to the data from Census and Statistics Department, in 2010, there was still 13% population aged above 65 years, while in 2039, this percentage will be elevated to 28% (http://www.censtatd.gov.hk/hkstat/sub/so20.jsp). In other words, every three individuals will contain a person aged above 65 years in the future 30 years. Therefore, how to release the medical burden resulted from aged tendency of population is the critical question in optimizing the treatment expenses.

Our aims in the cross-sectional study are to 1) estimate the number and percentage of nine body constitutions among population aged 65 and over in Hong Kong 2) identify the associations between nine body constitutions and other predetermined factors such as gender, weight, diet, body mass index (BMI), blood pressure, quality of life scale scores, et al.
