摘要: Seasonality is one of the oldest and most resistant-to-elucidation issues in suicide research. However, recent years epidemiological research has yielded new results, which provide perspectives on matter. This qualitative review summarizes published since 1990s. In particular, focus studies dealing with historical change seasonality, cross-sectional comparisons including method-specific diversity, association weather variables other putative covariates. Recent shown that Western countries seasonality tending to diminish may, eventually, disappear. It can no longer be considered a universal homogeneous phenomenon. addition, different major seasonal cycles have now been determined mainly depend methods. Just as epidemiology methods, (seasonal) availability perceived adequacy methods emerge driving force beyond phenomena suicide.
