| Objective To investigate the correlation between the onset of recurrent depressive disorder and seasonal meteorological changes in Shenzhen, and to provide references for the prevention and treatment of the disorder.Methods Data including medical records of inpatients with recurrent depressive disorder in a psychiatric hospital in Shenzhen from 2013 to 2017 and the meteorological data for the same period were collected. The correlation analysis was conducted between the monthly admission amount of recurrent depressive disorder and the meteorological factors in the same period. Then the influence of seasonal meteorological factors on the recurrence of depressive disorder was determined by multiple linear regression model.Results The maximum monthly admission for recurrent depressive disorder were May [85 cases (10.39%)], July [78 cases (9.54%)] and August [77 cases (9.41%)], and the highest seasons of admission were 226 cases (27.6%) in the fall, followed by 212 cases (25.9%) in the summer. There was no statistically difference in monthly hospital admission between different genders (χ2=9.947, P>0.05). The monthly admission of patients with recurrent depressive disorder was positively correlated with monthly average precipitation and relative humidity (r=0.292, 0.370, P<0.05), and negatively correlated with the average wind speed (r=-0.475, P<0.05). Multiple linear regression analysis showed that the admission volume of patients with recurrent depressive disorder was increased with the decrease of monthly wind speed and the increase of monthly mean humidity (P<0.05).Conclusion The incidence of recurrent depressive disorder is seasonal, and the changes of meteorological elements are associated with the incidence of the disorder, especially the changes of humidity and wind speed. |
