  1. Note: Kruskal Wallis tests were used for continuous variables (age, education) as these did not have normal distributions. Means and standard deviations are given for descriptive purposes only. BMI = Body Mass Index, ADL = Activities of Daily Living, IADL = Instrumental Activities of Daily Living, CES-D = Center for Epidemiologic Studies Depression Scale, TICS-R = Telephone Interview for Cognitive Status- Revised. Due to missing data for proxy interviews, the n for analyses using the CES-D is 1737 and 903 for the two groups. For analyses using the TICS-R, the n = 1693 and 878 for the two groups.
