Suicide and Occupation: Further Supportive Evidence for Their Relevance

In the present study, the relationship between occupation & suicide was investigated by examining Japanese governmental statistics. The authors found that suicide rate was positively correlated with primary industry: farmers, fishermen, & forest workers. Multiple regression analysis also showed that suicide rate was negatively associated with annual total sunshine. The authors theorize that since workers with primary industry are more likely to be exposed to sunshine than other workers, they may tend to be more affected by the decrease in annual total sunshine.
