[ロンドン 15日 ロイター] – 英科学者らが行った調査で、週3回運動するとうつ状態に陥るリスクが16%低下することが分かった。運動の回数が増えると、確率はさらに低下するという。

うつ病は世界で3億5000万人以上に影響を及ぼしている。投薬治療や心理療法などがあるが、再発に苦しむ患者が多いという。

調査は1958年生まれの1万1135人を対象に実施。50歳までを対象に、所定の質問に答えてもらい、うつの程度と運動の関係を調べた。

その結果、運動回数を増やした人の発症率がより低かったのに対し、特に若年層でうつ病を発症しやすい傾向にある人は、あまり活動的ではないことが分かった。週に1回運動回数が増えると、うつ状態に陥る確率は6%低下した。

調査を手掛けた1人は、この結果は運動が健康を増進するだけでなく、うつ病リスクへの対策としても有効なことをあらためて示したと指摘した。

In a study conducted as part of a public health research consortium, the UK-based scientists said the relationship they found between depression and exercise points to ways to simultaneously improve both mental and physical health.

“Assuming the association is causal, leisure time physical activity has a protective effect against depression,” said Snehal Pinto Pereira of University College London’s Institute of Child Health, who led the study.

“If an adult between their twenties and forties who isn’t physically active became active three times per week, they would reduce their risk of depression by approximately 16%.”

Depression is one of the most common forms of mental illness, affecting more than 350 million people worldwide. It is ranked by the World Health Organization as the leading cause of disability globally. Treatment for depression usually involves either medication or psychotherapy, or a combination of both.

Yet many patients fail to get better and suffer recurring bouts of illness. Pereira’s team followed 11,135 people born in 1958 up until the age of 50, recording their depressive symptoms and levels of physical activity at regular intervals as adults. To assess depression, they looked at responses to the Malaise Inventory, a questionnaire designed to measure psychological distress, at ages 23, 33, 42, and 50.

Participants were also asked how often they exercised. The results showed that people who increased their weekly activity reported fewer depressive symptoms, but those with more depressive symptoms were less active, particularly at younger ages. Each additional activity session per week reduced odds of depression by 6%.
