Health literacy can be defined as the capacity of individuals, families
and communities to access, understand, appraise and apply health
information in order to make judgements and take decisions in everyday
life concerning health care, disease prevention and health promotion in
order to maintain or improve their quality of life. It is considered to
be a social determinant of health, and one of the key pillars in health
promotion. Low health literacy is associated with poorer health, more
illness and health inequalities, and it may make health systems less
cost-effective.
Evidence from the 2011 health literacy survey indicated that almost half
of the adult population in eight Member States of the European Union had
suboptimal general health literacy. Responses have included initiation
of health literacy networks, policies, programs and interventions at the
regional, national and organizational levels. These initiatives require
monitoring using frameworks and indicator sets that produce consistent
and comparable population data and evaluation to determine the
effectiveness of the policies and interventions.
