Estimated Remaining Years of Life Gained, After Age 65, Among Different Representative Older Adults According to Plasma Phospholipid Total n3-PUFA.

Individual Characteristics	Years of Life Gained (95% CI) in the Highest vs. Lowest Quintile of Total n3-PUFA*
Female, white, education < high school †	2.22 (0.75, 3.13) †
Male, white, education < high school ‡	2.33 (1.01, 3.40) ‡
Male, white, college-educated	2.33 (0.95, 3.33)
Male, non-white, college-educated	2.31 (0.88, 3.24)
Male, non-white, college-educated, diabetic	2.33 (1.01, 3.52)
Male, non-white, college-educated, diabetic, current smoker	2.20 (0.92, 3.30)

^*Values are the multivariable-adjusted estimated years of life gained after age 65 in the highest quintile of total n-3 PUFA, compared to the lowest quintile as the reference, based on semi-parametric survival models (see Table 3).

^†These results are representative of a participant entering the study at age 65, with average (mean) values for each of the continuous covariates of body mass index (26.7 kg/ m²), waist circumference (96.8 cm), and leisure-time physical activity (1070 kcal/wk); and falling into the most representative category (mode) for each of the categorical covariates of sex (female), race (white), education (<high school), enrollment site (Forsyth County, North Carolina), fatty acid measurement batch (2007–10), smoking (never), prevalent diabetes (no), prevalent atrial fibrillation (no), prevalent drug-treated hypertension (no), and alcohol use (none).

^‡We also calculated the life-years gained for representative variations of the above individual, for example if the same individual were instead male (row two in the table); male and college-educated (row three); male, college educated, and nonwhite (row four); male, college-educated, nonwhite, and diabetic (row five); and male, college-educated, nonwhite, diabetic, and a current smoker (row six)

PUFA=polyunsaturated fatty acids.
