Mobility is fundamental to independent living, but past research on physical function and mobility in older adults has not considered both intersectional social identities and cohort change in tandem. This paper utilizes data on mobility limitations from older adults in multi-ethnic Singapore to test whether cohort change varies simultaneously by gender and ethnicity. Panel data (n = 9334 person-years) collected over six years (2009-2015) were used to estimate aging vector models. Findings show that after adjusting for all covariates, Malay and Indian males in later-born cohorts have an increased number of mobility limitations compared to earlier-born cohorts. While a similar trend was also found for Chinese males and females in unconditional models, these were fully mediated by sociodemographic and health variables. These results highlight the importance of considering cohort change at the intersection of gender and ethnicity, bringing attention to possible inequities between ethnic groups.

Identifying strong predictors for falls and mobility limitations in older adults with a falls-related emergency department visit is crucial. This study aimed to compare, in this clinical population, t...
To assess the association between exposure to physical workload throughout working life and risk of mobility limitations in midlife in a population-based Danish cohort.
Many older medical patients experience persistent functional limitations after hospitalization, such as dependency in activities of daily living, recurring fall incidents and increased mortality. Ther...
The self-reported health of foreign-born older adults (FBOAs) is lower than that of nonimmigrant peers. Physical activity (PA) and mobility enhance health in older age, yet we know very little about t...
To examine changes in tooth loss and untreated tooth decay among older low-income and higher-income US adults and whether disparities have persisted.
The loss of mobility during aging impacts independence and leads to further disability, morbidity, and reduced life expectancy. The study objective was to examine the feasibility and safet...
There is an urgent need for interventions to reduce mobility limitations that affect over 15 million older adults and contribute to falls, disability, hospitalization and death. This train...
Knee Osteoarthritis (OA) accounts for a significant proportion of mobility limitations and is one of the most disabling problems facing the growing population of older adults. The purpose...
The purpose of this study is to increase the physical activity among overweight individuals with mobility limitations.
Type 2 diabetes results in a host of neuromuscular, muscular, and autonomic system impairments that accelerate age-associated limitations in functional independence and the risk of falls. ...
Variation in health status arising from different causal factors to which each birth cohort in a population is exposed as environment and society change.
The upward or downward mobility in an occupation or the change from one occupation to another.
Frequent change of residence, either in the same city or town, or between cities, states or communities.
Monitoring of rate of occurrence of specific conditions to assess the stability or change in health levels of a population. It is also the study of disease rates in a specific cohort, geographic area, population subgroup, etc. to estimate trends in larger population. (From Last, Dictionary of Epidemiology, 2d ed)
An electrophoretic technique for assaying the binding of one compound to another. Typically one compound is labeled to follow its mobility during electrophoresis. If the labeled compound is bound by the other compound, then the mobility of the labeled compound through the electrophoretic medium will be retarded.
