Kathy Navaroli, 50, of Windsor, hadn’t seen a primary care doctor in years when she decided to go for a physical this summer. She didn’t ask about preventive care screenings, such as a mammogram or Pap test, in part because she worried they might involve an insurance co-pay or deductible. Her household income is below $30,000 a year. “I got a physical, they did some blood work, and that was it,” she said. Kerrishian McCants, 31, of Hartford, a mother of four, has a family history of diabetes and high blood pressure, but has not discussed those possible risks with her doctor.
