People who are in the manufacturing sector of the economy fear losing health insurance, despite the fact that its employees have historically not had to fear loss of coverage, a new survey finds.

Those in the manufacturing sector are now as worried about losing coverage as those in the arts, services, hospitality and retail occupations, all of which are traditionally unsecure sectors for health insurance, according to the survey, prepared by the Center for Healthcare Research & Transformation, based on polling of 1,022 adults in Michigan.

Their worry level in these sectors ranges between 40% and 52%.

By comparison, those in high-tech knowledge industries, government, and construction/natural resources/mining sectors were not as worried about losing coverage, with worry levels of 21%, the survey found.

While 40% of those who lacked insurance delayed seeking needed care, so did 17% of those with health insurance. Financial concerns were cited most frequently as the reason for not seeking care.

The survey also explored a connection between having health insurance and self-perceptions of health. Exactly 49% of those with health insurance reported themselves to be in excellent or very good health, while 47% of those with no health insurance reported themselves to be in excellent or very good health.

The survey was conducted in August 2009 by Michigan State University’s Institute for Public Policy and Social Research. The Center for Healthcare Research & Transformation sponsors research and public information to promote evidence-based health care delivery, improve population health, and expand access to care. Housed at the University of Michigan, CHRT is a partnership between the university and Blue Cross Blue Shield of Michigan.
