Abstract
The present study aims to analyze country-specific antidepressant consumption rates across 30 OECD countries, comparing them with the OECD average from 2010 to 2020. This analysis examines annual variations in consumption and identifies potential trends over time. Using a retrospective observational design, the study employs pooled secondary data from 30 OECD countries. A time trend analysis was conducted to assess overall and country-specific linear and quadratic trends, modeling the variation in Defined Daily Dose (DDD) per 1,000 inhabitants from 2010 to 2020. Findings reveal a significant increase in antidepressant consumption across most countries. The mean DDD value rose from 52.42 in 2010 to 69.5 in 2020. Three distinct trend patterns emerged: linear, concave, and convex. While 15 countries exhibited a significant linear increase, five showed a plateauing trend, and others experienced exponential growth with a convex trajectory. Denmark was the only country to show a decline in consumption, whereas Norway displayed no significant change over time. These results underscore a notable rise in antidepressant use across most OECD countries, alongside variations in consumption trajectories. By assessing and comparing national consumption rates, this study highlights the importance of international collaboration in addressing mental health challenges and optimizing healthcare accessibility and outcomes.
