マインドフルネスとは？よい習慣が多い10代ほど心が元気、5年追った研究

Beyond Sleep, Diet and Exercise, Teen Well-Being Builds Up

音声・ゲームはこちらから

1Teenagers who had more healthy habits and personal strengths reported better well-being years later, according to a study from Australia. Researchers at the Thompson Institute of the University of the Sunshine Coast published the work in the Journal of Adolescence, and the university announced it on October 13.

2The team used data from the Longitudinal Adolescent Brain Study, which has followed the same group of young people for up to five years. The participants, who were 12 to 17 years old, had brain scans and thinking tests. They also answered questions about their mental health and daily life.

3Sleep, diet and exercise are often called the big three for mental health. The researchers wanted to see whether other factors also mattered. They added social connectedness, or how close young people feel to others, and mindfulness, which means being present and engaged in daily life.

4Teens who had a greater number of these protective factors were more likely to report positive well-being and lower psychological distress at later checks. The link remained even after the team took the teens' earlier mental health into account. The factors also tended to cluster, so a teen with one strength often had others.

5The study was observational, so it shows an association rather than proof that the habits caused better well-being. The participants also came from one region of Australia. In a 2024 study of 103 young teens from the same project, the team found that social connectedness was the strongest predictor of both distress and well-being.

全文訳

1健康的な習慣や心の強みが多い10代ほど、数年後に心の元気さ（ウェルビーイング）が高いと答えていたことが、オーストラリアの研究でわかりました。サンシャイン・コースト大学トンプソン研究所の研究者たちが学術誌「ジャーナル・オブ・アドレッセンス」に発表し、大学が10月13日に公表しました。

2チームが使ったのは「思春期の脳の長期研究」のデータで、この研究は同じ若者のグループを最長5年間追いかけています。参加した12〜17歳の若者は、脳の画像の撮影や、考える力のテストを受けました。心の健康や毎日の生活についての質問にも答えました。

3睡眠・食事・運動は、心の健康のための「3大要素」とよく呼ばれます。研究者たちは、ほかの要素も関係するのかを確かめたいと考えました。そこで、人とのつながり、つまり若者がほかの人をどれだけ身近に感じているかと、マインドフルネス、つまり毎日の生活で「いま」に気持ちを向けて打ちこめているかを加えました。

4こうした心を守る要素を多く持つ10代ほど、あとの調査で、心が元気で、精神的なつらさが少ないと答える傾向がありました。チームがその10代の以前の心の状態を考えに入れても、この関係は残りました。また、これらの要素はまとまって現れる傾向があり、1つの強みを持つ10代は、ほかの強みも持っていることが多くありました。

5この研究は観察による研究なので、わかったのは関係であって、習慣が心の元気を生んだという証明ではありません。また、参加者はオーストラリアの1つの地域の若者でした。同じ研究プロジェクトの若い10代103人を調べた2024年の研究では、人とのつながりが、精神的なつらさと心の元気さの両方をいちばんよく予測する要素でした。

文法ポイント：関係代名詞 who（～する人）

who のうしろの文が、前の「人」を説明する。本文の Teens who had a greater number of these protective factors were more likely to ... は「こうした心を守る要素を多く持つ10代は…しやすかった」。主語の Teens と動詞 were のあいだに、who ～ factors という長い説明が入っているので、どこまでが主語かを見きわめるのが長文読解のコツ。
