Trajectories of middle-aged and elderly people’s chronic diseases Disability Adjusted Life Years (DALYs): cohort, socio-economic status and gender disparities

Abstract

Background The accelerated aging trend brought great chronic diseases burdens. Disabled Adjusted Life Years (DALYs) is a novel way to measure the chronic diseases burden. This study aimed to explore the cohort, socioeconomic status (SES), and gender disparities of the DALYs trajectories. Methods A total of 15,062 participants (55,740 observations) comes from China Health and Retirement Longitudinal Study (CHARLS) from 2011 to 2018. Mixed growth curve model was adopted to predict the DALYS trajectories in 45–90 years old people influenced by different birth cohorts and SES. Results We find significant cohort, SES (resident place, education level and income) disparities differences in the chronic diseases DALYs. For individuals of earlier cohort, DALYs are developed in a late age but grow fast with age but reversed for most recent cohorts. Living in urban, having higher SES level will decrease the growth rate with age, but converges for most recent cohorts. Meanwhile, DALYs disparities of resident place and education level show gender differentials that those for female are narrowed across cohort but for male are not. Conclusions The cohort effects on chronic diseases DALYs are accumulated with China’s unique social, and political settings. There are large inequalities in early experiences, SES and DALYs. Efforts of reducing these inequalities must focus on the lower SES individuals and those living in rural areas, which greatly benefit individuals from recent cohorts.

Association between Selenium Status and Chronic Kidney Disease in Middle-Aged and Older Chinese Based on CHNS Data

“…Among them, selenium is best known in the form of antioxidant enzymes such as GPx3, the strongest antioxidant enzyme in the body [8][9][10]. The middle-aged and elderly are the populations with a high incidence of various chronic diseases [11]. Studies have shown that a lack of selenium intake was associated with cognitive impairment [12], hypertension [13], and Alzheimer's disease [14,15].…”

Psychometric evaluation of the Chinese version of Self-assessment scale for the community- based and emergency practice among medical students

“…[5] As they enter old age, older people present health characteristics that are different from those of the general population, such as susceptibility to infectious diseases, the coexistence of chronic diseases, nutritional de ciencies, frailty, the prevalence of falls, "disability and dementia", and signi cant mental health and mental health problems. [6,7] The age structure of China's population is changing from "adult" to "elderly", and the rapid change in family structure poses serious challenges to healthcare services and long-term care service models. [8,9] In the process of rapid demographic transition and economic and social development changes, the needs of the elderly are increasingly diversi ed, evolving from purely individual or family needs to social needs.…”
