Neglect and self-rated health among older adults - a cross-sectional study in Poland.

The aim of this cross-sectional study is to examine if neglect is associated with self-rated health (SRH) and if neglect mediates the association between selected factors and self-rated health, among older men and women. The analyses were based on face-to-face computer-assisted personal interviews conducted with 1632 randomly selected community-dwelling individuals aged 65 years and more from among the general population of Lesser Poland. The regression models' analysis revealed that elder neglect was associated with self-rated health, and the mediation analysis demonstrated that neglect mediates the association between frequency of church attendance and SRH, as well as between marital status (being a widower vs being married) and SRH, among men.
