Thank you for your question. This took a little searching for information but hopefully this will give you a little something to read. I am providing one link which is to the National Institute on Aging which can be referenced here http://www.nia.nih.gov/.
Another informational site specific to the region of Macau can be found here http://www.umac.mo/dc/dissertation/dissertation_PDF/fba/mba%28ms%29/mba_ms_076.pdf.
This website provides a sleuth of information about the region including disease and so forth. I hope this helps answer your question.
