table_health

Description

Associations of biological aging measures with healthspan-related characteristics.

Usage

table_health(data, agevar, outcome, label)

Arguments

data	A dataset with projected biological aging measures for analysis.
agevar	A character vector indicating the names of the biological aging measures.
outcome	A character vector indicating the name of the healthspan-related characteristics.
label	A character vector indicating the labels of the biological aging measures.

Details

Coefficients are from linear regressions of healthspan-related characteristics on biological aging measures. Outcome variables were standardized to have M=0, SD=1 for analysis. KDM Biological Age and Levine Phenotypic Age measures were differenced from chronological age for analysis (i.e. values = BA-CA). These differenced values were then standardized to have M=0, SD=1 separately for men and women within the analysis sample so that effect-sizes are denominated in terms of a sex-specific 1 SD unit increase in biological age advancement. Models included covariates for chronological age and sex.

Value

The result is a list with two elements (table and n). The regression table can be drawn by typing 'table'. The sample size table can be drawn by typing 'n'.

Note

Chronological age, gender, and race/ethnicity variables need to be named "age", "gender", and "race".

Examples

table2 = table_health(data,
                      agevar = c("kdm_advance0","phenoage_advance0",
                               "kdm_advance","phenoage_advance",
                               "hd","hd_log"),
                      outcome = c("health","adl","lnwalk","grip_scaled"),
                      label = c("KDM\nBiological Age\nAdvancement",
                                "Levine\nPhenotypic Age\nAdvancement",
                                "Modified-KDM\nBiological Age\nAdvancement",
                                "Modified-Levine\nPhenotypic Age\nAdvancement",
                                "Homeostatic\nDysregulation",
                                "Log\nHomeostatic\nDysregulation"))
