Studies show that the season of the year often affects our mental health. But do seasons affect all age groups equally? Researchers investigated just that!

Alaskan and Canadian researchers used admission records from the New Brunswick Hospital Discharge Database.  They examined whether there was a trend of seasonal mental-health related hospitalizations comparing children, adolescents, and adults between 2004 and 2014. These researchers reviewed over 41,000 patient records.

Researchers found a general increase in mental-health-related hospital admissions for children and adolescents between 2004 and 2014. For both children and adolescents, peak admissions occurred during February with lows during the summer. The winter increase is likely due to academic pressures to achieve. And, school staff more likely interact and identify mental health issues, and make referrals during the school year.

The peak admissions for adults, in contrast, occurred in April-May with lows in December. When the weather warms, there are also more social opportunities with increased social pressures. This may exacerbate mental health issues for adults.

These findings support identifying complex factors that influence mental health problems and psychiatric admissions. This suggests: help youth by decreasing academic stressors.
