Study Reference ID

S70504

Simple summary

We examine whether warmer weather is associated with more anxiety/depression or with more prescriptions for antidepressants and sedatives. We compare event days with similar referent days. Analyses are at group level; privacy is safeguarded.

Technical Summary

We assess the association between ambient temperature and new episodes of depression and anxiety, as well as prescriptions of psychoactive medication, in adults. We conduct a time‑stratified aggregated case‑crossover study using Intego data (2012–2021; >650,000 patients). Diagnoses (ICPC‑2) and prescriptions (ATC) are linked to daily maximum/minimum temperature and relative humidity at the residential address (April–September), with environmental data provided by VITO.

Health outcomes

Registered diagnoses of anxiety and depression, and prescriptions for antidepressants and benzodiazepines.
