Information collected by the National Gay Rights Advocates in 1986 and by the authors in the spring of 1987 was used to determine the extent to which the states currently regulate the practices of the health insurance industry specific to acquired immunodeficiency syndrome (AIDS).

These findings refer only to the status of state regulatory activity specific to AIDS.
