Suitability of public use secondary data sets to study multiple activities

Area of Science:

• Gerontology
• Public Health Research
• Sociology of Aging

Background:

• Understanding the diverse activities older adults engage in is crucial for promoting health and well-being.
• Existing large-scale U.S. data sets offer potential for studying patterns of activity engagement among older populations.
• Gaps in current data limit comprehensive analysis of multiple activity engagement and its health implications.

Purpose of the Study:

• To inventory and compare activity items across major U.S. public use data sets.
• To identify gaps in represented activity domains and challenges in domain interpretation.
• To assess the feasibility of studying multiple activity engagement in older adults using existing data.

Main Methods:

• Content analysis of activity measures from five U.S. public use data sets.
• Analysis included nationally representative samples of older adults from the Health & Retirement Survey (HRS), Americans' Changing Lives Survey (ACL), Midlife in the United States Survey (MIDUS), National Health Interview Survey (NHIS), and Panel Study of Income Dynamics (PSID).
• Two waves of data from each survey were examined.

Main Results:

• Thirteen distinct activity domains were identified across the five data sets.
• Significant variation existed in the representation of these domains among the data sets.
• The number and types of activity measures varied considerably within each data set.

Conclusions:

• Studying multiple activity engagement among older adults is feasible with existing data, but limitations exist.
• Development of more comprehensive activity measures is necessary to evaluate activity portfolios.
• Clearer conceptual models are required to guide research on the relationship between activity portfolios and health outcomes in older adults.
