まとめ
晩年の就労開始は、高齢のブラジル人における認知機能の向上と関連している。早期就労の遅延が高齢期の脳の健康に有益である可能性が示唆される。
科学分野:
- 認知神経科学;老年学;健康の社会経済的決定要因
背景:
- ブラジルにおける経済的困難は、しばしば16歳以前の早期労働力への参加につながります。
- 早期就労が正規教育に与える影響は知られていますが、晩年の認知機能への影響はあまり明確ではありません。
- 早期就労は認知刺激を提供する可能性があり、晩年の認知機能に有益である可能性があります。
研究 の 目的:
- 早期就労年齢と晩年の認知機能との関連性を調査すること。
- 早期就労開始に基づく見当識、記憶、言語流暢性における認知パフォーマンスを分析すること。
- ブラジルの全国コホートにおける早期労働力参加と認知老化との関係を理解すること。
主な方法:
- ブラジル高齢化縦断研究(ELSI-Br)のデータを利用しました。
- 見当識、記憶、言語流暢性を評価し、記憶および流暢性スコアを年齢と性別で標準化しました。
- 線形回帰モデルを採用し、就労開始年齢(10歳以下、11〜15歳、16歳以上)を分類し、人口統計学的および社会経済的要因を調整しました。
主要な成果:
- 参加者のかなりの割合(41.74%)が10歳またはそれ以前に働き始めていました。;11〜15歳および16歳以降に働き始めた個人は、10歳以前に働き始めた人と比較して、より高い見当識と記憶スコアを示しました。;言語流暢性は、16歳以降に働き始めた人で改善する傾向が見られました。
結論:
- 早期労働力への参加は、晩年の認知機能と関連しています。
- 早期就労の遅延が高齢のブラジル人の認知機能に有益である可能性を示唆しています。
- 結果は、脆弱な集団における教育の促進と早期就労の遅延を目的とした政策に情報を提供できます。
