The inverse relationship between income and the prevalence of dementia in high-income nations
* Author to whom correspondence should be addressed.
Abstract
Dementia continues to be a serious problem worldwide. A negative relationship between the prevalence of dementia and the level of socioeconomic status (SES), such as income can be observed in most countries. The aim of the study in this paper is to explore the possible pathways that contribute to this negative relationship. This article analyses and presents three possible causes of health inequalities between SES gradients in dementia and possible solutions to them, through a large collection of articles. Differences in health literacy, housing levels and social support caused by SES such as different incomes lead to social inequalities in health through behavioral/cultural pathway， material pathway and psychosocial pathway respectively.
