OBJECTIVES. This study addresses three issues. (1) What are demographi
c wealth, employment, and health characteristics of near-elderly perso
ns losing or acquiring health insurance coverage? Specifically, (2) wh
at are the effects of life transitions, including changes in employmen
t status, health, and marital status? (3) To what extent do public pol
icies protect such persons against coverage loss, including various st
ate policies recently implemented to increase access to insurance? MET
HODS. The authors used the 1992 and 1994 waves of the Health and Retir
ement Study to analyze coverage among adults aged 51 to 64 years. RESU
LTS. One in five near-elderly persons experienced a change in insuranc
e coverage from 1992 to 1994. Yet, there was no significant change in
the mix of coverage as those losing one form of coverage were replaced
by others acquiring similar coverage. CONCLUSIONS. Individuals whose
health deteriorated significantly were not more likely than others to
suffer a subsequent loss of coverage, due to substitution of retiree o
r individual coverage for those losing private coverage and acquisitio
n of Medicaid and Medicare coverage for one in five uninsured. State p
olicies to increase access to private health insurance generally did n
ot prevent individuals from losing coverage or allow the uninsured to
gain coverage. Major determinants of the probability of being insured
were education, employment status of person and spouse, and work disab
ility status. Other measures of health and functional status did not a
ffect the probability of being insured, but had important impacts on t
he probability of having public coverage, conditional on being insured
