Research from the ongoing Population Study of Chinese Elderly (PINE), in Chicago, was carried in the recent The Journal of Gerontology: Medical Sciences Volume 72:S1.

Researchers doctors Man Guo, Ling Xu, and Xin Qidong from the PINE study interviewed more than 3000 elderly Chinese immigrants living in the US.
