Background: Seasonality in suicide has been investigated from the early 19th century to explore the productive environmental variables. Seasonality studies can provide information on prevention and interventions in suicide. In this study, we examined seasonality in suicide and aimed to explore the differences in seasonality between rural and urban areas, mental disorders, and genders. Method...

the main objective of the present study was to determine the association between completed suicides and season of the year in iran during 2006-2010.data on completed suicides were collected by questionnaires field out by the family members of the victims in legal medicine centers throughout the country over the period from 2006 to 2010. the maximum number of completed suicides (380) was observe...

background there are few quantitative documents about the seasonal incidence of tuberculosis (tb) among immigrant populations. concerning the significant role of recognizing seasonal changes of tb in improving the tb control program, this study determines the trend and seasonal temporal changes of tb among immigrants entering iran.   methods in this longitudinal study, data from the iranian tb ...

Correlation in space between seasonality of malaria and seasonality of rainfall was studied in Sri Lanka. A simple seasonality index was developed by making use of the bimodal seasonality of both malaria and rainfall. The malaria seasonality index was regressed against the rainfall seasonality index taking spatial autocorrelation into account. Despite the presence of spatial autocorrelation, th...

A description of malaria seasonality is important for planning and optimizing malaria control in both time and space, but adequate malariologic data are not available for many disease-endemic areas. We analyzed the relationship between seasonality in the entomologic inoculation rate (EIR) and environmental factors in sites across sub-Saharan Africa with the objective of predicting seasonality f...

the aim of this study was to find out whether there is seasonality of month of birth in children with diabetes in mashhad and if so whether it differs from that of general papulation. 161 children and adolescents (0-18 years) with type 1 diabetes born between 1983-2001 were included the study. the results were analyzed by student’s t test and chi-square test and a p value<0.05 was considered si...

[1] Insect outbreaks are significant disturbances in forests of the western United States, with infestation comparable in area to fire. Outbreaks of mountain pine beetle (Dendroctonus ponderosae Hopkins) require life cycles of one year with synchronous emergence of adults from host trees at an appropriate time of year (termed ‘‘adaptive seasonality’’) to overwhelm tree defenses. The annual cour...

BACKGROUND Seasonal variations in mood and behaviour, termed seasonality, are commonly reported in the general population. As a part of a large cross-sectional health survey in Hordaland, Norway, we investigated the relationship between seasonality, objective health measurements and health behaviours. METHODOLOGY/PRINCIPAL FINDINGS A total of 11,545 subjects between 40-44 years old participat...

BACKGROUND Seasonality of suicides is well-known and nearly ubiquitous, but recent evidence showed inconsistent patterns of decreasing or increasing seasonality in different countries. Furthermore, strength of seasonality was hypothesized to be associated with suicide prevalence. This study aimed at pointing out methodological difficulties in examining changes in suicide seasonality. METHODODOL...
