A dataset on body composition, strength and performance in older adults

Area of Science:

• Gerontology
• Biostatistics
• Human Physiology

Background:

• The Rancho Bernardo Study (RBS) is a longitudinal observational cohort study initiated between 1972-1974.
• Community-dwelling adults in Rancho Bernardo, California, were eligible for participation.
• A subset of participants attended follow-up visits every four years.

Purpose of the Study:

• To present a comprehensive dataset of body composition, strength, and performance measurements.
• To facilitate further research into the interrelationships between these metrics in older adults over extended periods.
• To provide data for advanced statistical modeling.

Main Methods:

• Data were collected from Visits 7-10 of the RBS.
• The dataset includes measurements from 1466 subjects with at least one recorded measure.
• Structural equation modeling was used to fit a feed-forward loop model for data analysis.

Main Results:

• The dataset captures longitudinal changes in body composition, strength, and performance.
• Analysis using a feed-forward loop model reveals interdependencies between these variables.
• The findings contribute to understanding the aging process in relation to physical capabilities.

Conclusions:

• The presented dataset is a valuable resource for researchers studying aging and physical function.
• The data support the development of predictive models for health outcomes in older adults.
• Further exploration of the data can yield deeper insights into the complex interplay of factors affecting healthy aging.
