Past Meal-Skipping Habits Associate With Physical Frailty in Later Life: A Retrospective Cohort Study

Area of Science:

• Gerontology
• Nutritional Science
• Public Health

Background:

• Dietary habits significantly influence healthy longevity.
• Understanding the long-term impact of meal-skipping on physical health is essential for preventative strategies.

Purpose of the Study:

• To investigate the association between meal-skipping in early and midlife and physical frailty in later life.
• To identify critical periods for dietary interventions to prevent frailty.

Main Methods:

• Retrospective cohort study of 5063 community-dwelling older adults (≥65 years) in Japan.
• Meal skipping defined as ≤2 meals/day; physical frailty assessed using established criteria.
• Binomial logistic regression analyzed the odds ratios (ORs) for later-life frailty, adjusting for confounders.

Main Results:

• Meal skipping in both early and midlife was linked to increased odds of later-life physical frailty.
• Starting meal skipping in midlife or continuing it from early life showed higher frailty prevalence.
• Midlife meal skipping was associated with frailty even if regular eating resumed later.

Conclusions:

• Establishing regular eating patterns, especially during midlife, is vital for preventing physical frailty in older age.
• Interventions promoting consistent meal consumption may reduce the burden of frailty in aging populations.
