Development and Feasibility of an eHealth Diabetes Prevention Program Adapted for Older Adults-Results from a...

Area of Science:

• Gerontology
• Public Health
• Behavioral Medicine

Background:

• Older adults face challenges with traditional lifestyle programs, including adherence and attendance issues.
• Reduced energy needs, mobility, transportation, and social support hinder participation in weight loss (WL) programs for seniors.
• Tailored interventions are crucial for effective healthy aging and weight management in this demographic.

Purpose of the Study:

• To develop and pilot an age-adapted, remotely delivered modification of the Diabetes Prevention Program (DPP) for older adults.
• To assess the feasibility, fidelity, adherence, and engagement of a remote WL program for diverse older adults.
• To evaluate the clinical effectiveness of the remote DPP in promoting significant weight loss in older adults.

Main Methods:

• A modified Diabetes Prevention Program (DPP) was adapted for remote delivery, incorporating age-appropriate content, flexible diets, and remote monitoring technology.
• Twenty older adults (55-85 years, BMI 27-39.9 kg/m²) were randomized to either the online DPP intervention or a waitlisted control group.
• Intervention included remote monitoring of weight, diet, and activity, alongside standardized online classroom materials.

Main Results:

• The remote DPP intervention group achieved 100% attendance and adherence to self-monitoring.
• The intervention group experienced a mean body weight change of -9.5% (±4.1%), with 90% achieving ≥ 5% weight loss.
• In contrast, the control group showed a mean weight gain of 2.4% (±1.8%).

Conclusions:

• Remote interventions are feasible and effective for older adults, contrary to previous assumptions.
• This age-adapted, remotely delivered DPP can maintain fidelity, enhance adherence and engagement, and achieve clinically significant weight loss.
• The study provides standardized materials for future implementation of remote WL programs for healthy aging.
