For example, strategies for eliminating the cost of access to benefits, medicine and tests can be universal (public supply and/or full subsidies for private providers) or targeted (expansion of the public supply in areas of high vulnerability or partial subsidies and co-payments, according to ability to pay). As for information and awareness about pregnancy care, targeted proximity-based and social assistance strategies can be used, as can mass media and universal sexuality education campaigns. As will be seen below, the increase in contributory coverage in health systems has made for greater access and, especially, better quality in terms of maternal and child benefits. It is true that part of this increase in contributory coverage is not due to a net increase in contributors through pension plans or payroll deductions in contributory models, but rather to flexibility mechanisms or the incorporation of the non-contributing population into contributory formats.
