Description
Mingyue Hu builds a tool that estimates an older person's chance of developing cognitive impairment over six years. The model comes from a national Chinese longevity survey, using 10,053 participants followed for a median of about five and a half years. In that time, 1,750 people, about seventeen percent, developed impairment, and many others died, which the analysis treats as a competing risk.
Eight easy-to-collect factors drive the predictions, chosen with a mix of statistics and clinical judgment. The model separates future cases from non-cases fairly well and held up when tested on an earlier survey wave. It works best in the younger old, ages sixty-five to seventy-four. Nearly half the impairment risk traces to factors people can change.
