Final answer:
According to the study by Domenech-Abella et al., low socioeconomic status is linked to an increased risk of earlier death in older adults. Bereavement due to widowhood can also affect elderly mistreatment risk, while high physical activity is beneficial and not a risk factor.
Step-by-step explanation:
The study by Domenech-Abella et al. indicates that low socioeconomic status is linked to an increased risk of earlier death in older adults. This is reinforced by various research studies and historical data that suggest that individuals with lower socioeconomic status often have less access to healthcare, may have jobs with higher physical demands, and have increased levels of stress, all of which can contribute to a poorer health outcome and earlier mortality. Additionally, longevity research suggests the importance of social networks and support in improving life expectancy.
Bereavement, especially due to widowhood, can significantly increase the risk of mistreatment among the elderly. Being a widower or widow often results in decreased social support and increased isolation, which can lead to poor mental and physical health outcomes. Moreover, in high-income nations, many deaths are linked to lifestyle-related causes such as cancer, obesity, and mental illness, rather than factors like frequent travel or delayed marriage.
Physical activity is actually associated with lower mortality rates and increased life expectancy, making it an important factor in promoting health in middle and late adulthood. Regular exercise and good nutrition can greatly reduce the physical declines associated with aging and are not linked to an increased risk of earlier death.
