A groundbreaking longitudinal study from Melbourne's Murdoch Children's Research Institute (MCRI) has shed light on the alarming prevalence of anxiety and depression among adolescents, particularly girls. The study, published in Lancet Psychiatry, tracked 1,239 children from age 10 to 18, revealing that a staggering 64% experienced at least three episodes of anxiety or depression during their teenage years, with girls significantly more likely to exhibit persistent symptoms.

Professor Susan M. Sawyer, a leading adolescent health expert at MCRI, highlighted the study's key findings, noting that periods of heightened anxiety and depression often coincided with major life transitions like school graduations. She emphasized the importance of increased mental health awareness and reduced stigma, contributing to higher reporting rates.

The study also indicated that puberty and the stress of transitioning to secondary education likely contribute to the surge in anxiety and depression around ages 12-13. While the COVID-19 pandemic exacerbated the issue, the study suggests that it only accounted for about 25% of reported cases, underscoring the pre-existing nature of the problem.

The role of social media is a growing concern. While Australia considers a ban for users under 16, Sawyer believes a more nuanced approach is necessary. She advocates for delaying access to social media, fostering independent skills, and creating safer online environments for young people.

Addressing this crisis requires a shift towards preventative measures. Sawyer stresses the importance of prioritizing mental health in schools and fostering a culture of well-being. She believes that focusing on a healthy physical environment, increased exposure to nature, reduced sedentary lifestyles, and emphasizing overall well-being are crucial steps in combating this widespread issue.
