Women find it harder than men to pay for health care even if they are insured, a new study finds.

A study for the Commonwealth Fund by the Woman’s Law Center, Washington, found 68% of uninsured women did not get needed healthcare because they couldn’t afford it, but that even for women with insurance, 33% also had problems affording care. In contrast, about 49% of uninsured men reported being unable to afford needed care, compared to 23% of insured men.

The study also found that 31% of women with health insurance had problems paying medical bills, compared to 22% of insured men.

Around 17% of women were uninsured, compared to about 20% of men, the study found.
