Multivariable Association of 3-Year Weight Change With Survival to Age 100 vs Death Before Age 100 Among Older Women, 1993 to 2022

Variable	No./Total (%) Survived to Age 100, y*	OR (95% CI)†
No./total (%) survived to age 100	829/9 050 (9.2)
3-Y weight change‡
Stable weight (within ± 5% change)	621/6 137 (10.1)	1.00
Weight loss (≥5%)	113/1 858 (6.1)	0.62 (0.49, 0.78)
Weight gain (≥5%)	95/1 055 (9.0)	0.94 (0.73, 1.22)

^*Three-year weight change categories significantly differed by survival to age 100 (p < .001).

^†Models adjusted for age, study component (Observational Study or Clinical Trial), race, ethnicity, education, marital status, alcohol, smoking, diet quality, physical activity, physical function, body mass index, coronary heart disease, diabetes, stroke, cancer, emphysema, and hypertension.

^‡Intention of weight loss could not be examined due to low sample size.
