Life-space mobility describes the extent of community mobility of older persons. The aim of this cross-sectional study was to examine the relationship between socioeconomic status (SES) and life-space mobility and to investigate whether associations might be explained by SES-related disparities in health and functioning. The participants (n = 848) were community-dwelling adults aged 75–90. Education and occupation were used to indicate SES. Life-space assessment (range 0–120) was used to indicate distance and frequency of moving and assistance needed in moving. People with low education had lower life-space mobility scores than those with intermediate or high education: marginal means 63.5, 64.8, and 70.0 (p = .003), respectively. SES-related health disparities, i.e., higher body mass index, poorer cognitive capacity, and poorer physical performance explained the association, rendering it nonsignificant (marginal means 65.2, 65.3, and 67.5, p = .390). Low SES and restricted life-space mobility often coexist with overweight, reduced cognition, and poorer physical performance.

The aim of this study was to identify determinants of walking and whether walking maintained mobility among women as they transition from their mid-70s to their late 80s. We used 12 years of follow-up data (baseline 1999) from the Australian Longitudinal Study on Women’s Health (n = 10,322). Fifteen determinants of walking were included in the analysis and three indicators of mobility. Longitudinal data analyses techniques were employed. Thirteen of the 15 determinants were significant predictors of walking. Women in their mid-70s who walked up to 1 hr per week were less likely to experience loss of mobility in very old age, including reduced likelihood of using a mobility aid. Hence, older women who do no walking should be encouraged to walk to maintain their mobility and their independence as they age, particularly women in their 70s and 80s who smoke, are overweight, have arthritis, or who have had a recent fall.

While mobility is key to functional independence in aging, the influence of the local environment has only recently been included in human aging research ( Cunningham & Michael, 2004 ). In older adults, the capacity to move through the environment (mobility) affects functional independence and

Balance or postural control is a complex motor mechanism receiving input from various systems in the body. Balance is the ability to maintain position, undertake activities and retain good mobility (the ability to move safely and efficiently within the environment without falling). The three main

Mobility, the ability to move independently, is critical to maintaining independence and quality of life. Among older adults, mobility disability results when an individual cannot meet the demands of the environment. Current approaches to defining mobility rely on distance and time measures, or decompose mobility into subtasks (e.g., climbing, sit to stand), but provide limited understanding of mobility in the elderly. In this paper, a new conceptual framework identifies the critical environmental factors, or dimensions, that operationally define mobility within a given community, such as ambient conditions (light levels, weather conditions) and terrain characteristics (stairs, curbs). Our premise is that the environment and the individual conjointly determine mobility disability. Mobility in the elderly is defined not by the number of tasks a person can or cannot perform, but by the range of environmental contexts in which tasks can be safely carried out: the more disabled, the more restrictive the dimensions.

/vitamin D consumption ( Baugreet, Hamill, Kerry, & McCarthy, 2017 ). These nutrients play a vital role in muscle health. Loss of healthy muscle is associated with physical disability, reduced physical activity, decreased mobility, lower muscle strength, and limited muscle endurance ( Rolland et al., 2008
