Weighted lifetime BIIP prevalence estimates among older age groups

65–74 N = 4,186 75–84 N = 2,878 85+ N = 879 TOTAL N = 7,943
Lifetime BIIP with or without 12-month SP 4.2 (3.4–5.0) 4.6 (3.7–5.5) 3.3 (2.0–4.5) 4.2 (3.7–4.8)
Lifetime BIIP with 12-month SP 0.6 (0.3–0.9) 0.5 (0.3–0.7) 0.5 (0.04–1.04) 0.6 (0.4–0.8)

Note: The results of binary logistic regression analyses indicated that there were no significant age-related differences in BIIP prevalence among older adults.
