Topic: longitudinal study

This workshop introduces the Health and Retirement Study, a nationally representative longitudinal study of Americans older than 50. It explains the study’s complex survey design, available subject matter, and the RAND HRS resources that simplify analysis. Practical exercises then cover data structure, basic data management, and analysis using sample weights and design variables. Breakout discussions provide opportunities to ask the study team questions and consider applications to participants’ own research. The session is designed to help new users begin working with the study’s public aging

In vision, there is, surprisingly, very little evidence of common factors. Most studies have found only weak correlations between performance in different visual tests; meaning that, a participant performing better in one test is not more likely to perform also better in another test. Likewise in ageing, cross-sectional studies have repeatedly shown that older adults show deteriorated performance in most visual tests compared to young adults. However, within the older population, there is no evidence for a common factor underlying visual abilities. To investigate further the decline of visual
