インペリアル・カレッジ・ロンドンとコヴェントリー大学の研究によると、高齢者が加齢を前向きに捉えることは、転倒後の身体的回復に良い影響を与えると判明しました。英国の60〜90歳約700人を1年間追跡した結果、前向きな自己認識を持つ人は、歩行速度の低下リスクが162%、他者依存が200%、身体活動の減少が123%低くなりました。この効果は他の健康要因を考慮しても維持されており、前向きな加齢意識が高齢者の健康維持に役立つ可能性が示されました。

高齢者の回復に影響する加齢に対する前向きな姿勢の効果(Positive mindset about ageing in over-60s linked to better recovery after a fall)

ABSTRACT

Objective

To investigate how mindsets around aging at baseline affect physical recovery following a subsequent fall.

Design

Longitudinal observational study.

Setting

English Longitudinal Study of Aging (ELSA).

Participants

We analyzed data for 694 individuals who had not fallen in the 2 years prior to baseline (Wave 4) but experienced a fall during follow-up (between Waves 4 and 5).

Measurements

Self-perceptions of aging at baseline (Wave 4) and gait speed, activities of daily living (ADL) dependence, and physical (in)activity after a fall at a 2-year follow-up (Wave 5). Multivariable logistic regression analyses were used to determine to what extent aging-related mindset variables as measured at baseline predicted outcome measures at follow-up.

Results

In a fully-adjusted model controlling for confounding baseline factors (including baseline gait speed, ADL dependence and physical inactivity), individuals with positive self-perceptions of aging at baseline had significantly lower odds of slow gait speed (OR = 0.729; 95% CI = 0.627–0.849), ADL dependence (OR = 0.667; 95% CI = 0.561–0.792) and physical inactivity (OR = 0.795; 95% CI = 0.700–0.904) following a fall at a 2-year follow-up.

Conclusions

These findings identify self-perceptions of aging as a strong predictor of physical recovery and disability following a fall, independent of other important factors such as age, gender, and pre-fall physical function. These novel observations advance our understanding of the psychological factors impacting physical recovery from a fall. Future work should explore if targeting such perceptions can directly improve physical recovery and outcomes following a fall.

Summary
  • Key points

○This study provides the first evidence that older individuals who had more positive self-perceptions of aging at baseline were better protected against negative physical consequences following a subsequent fall.

○These results remained statistically significant after adjusting for important covariates including baseline gait speed, ADL dependence and physical inactivity, identifying self-perceptions of aging as an important independent predictor of physical recovery following a fall.

○These novel findings highlight the potential of psycho-social factors to influence physical recovery from a fall in older adults.

  • Why does this paper matter?

○The present findings identify self-perceptions of aging as a robust predictor of physical function and disability following a fall, independent of other important factors such as age, gender, and pre-fall physical function.

○These novel observations advance our understanding of the psychological factors impacting physical recovery from a fall and suggest that assessment of self-perceptions of aging could help identify older adults requiring additional support following a fall.

○This could lead to enhanced recovery outcomes for older adults, ultimately reducing the burden of disability and improving quality of life after falls.
