Final answer:
It is estimated that elder abuse affects between 4.6% and 5.2% of older adults every year, with women and those with health issues being particularly at risk. The actual number may be higher due to underreporting.
Step-by-step explanation:
The question you've asked pertains to the prevalence of elder abuse. Taking into account the findings from Acierno's study, which showed that a percentage of respondents aged more than 60 years reported various forms of abuse, as well as other research indicating that about one in ten elderly people surveyed had suffered some form of elder abuse, it can be estimated that between 4.6% and 5.2% of older adults experience abuse each year. However, given that some cases go unreported and considering the large population of older adults, the numbers could be even higher. Women are particularly vulnerable, and those with health issues, such as dementia, face increased risks.
