"Active Guide" Brochure Reduces Sedentary Behavior of Elderly People: A Randomized Controlled Trial

Area of Science:

• Gerontology
• Public Health
• Behavioral Science

Background:

• Sedentary behavior is a significant health concern among community-dwelling elderly populations.
• Reducing sitting time is crucial for maintaining health and independence in older adults.
• Evidence-based interventions are needed to promote physical activity and decrease sedentary lifestyles in the elderly.

Purpose of the Study:

• To evaluate the effectiveness of the
• Active Guide" brochure and supplementary educational materials in reducing sedentary behavior among community-dwelling elderly Japanese subjects.
• To quantify the change in sedentary behavior rates after a one-year intervention using a randomized controlled trial design.

Main Methods:

• A randomized controlled trial was conducted with 86 elderly participants engaged in health club activities.
• Participants were allocated to an intervention group (n=42) receiving the brochure and documents, or a control group (n=44) not receiving them.
• Sedentary behavior was objectively measured using triaxial accelerometers at baseline and after one year.

Main Results:

• The intervention group demonstrated a significant decrease in sedentary behavior rate by -2.2% from baseline after one year (n=40).
• The control group showed an increase in sedentary behavior rate by +2.5% from baseline over the same period (n=40).
• The difference in sedentary behavior reduction between groups was statistically significant (Welch's t-test, p=0.007).

Conclusions:

• The "Active Guide" brochure and associated documents are effective in reducing sedentary behavior in community-dwelling elderly Japanese individuals.
• Public health initiatives utilizing educational materials can successfully promote reduced sitting time in older adults.
• Interventions targeting sedentary behavior are vital for improving the health outcomes of the aging population.
