Background: Stronger associations between modifiable risk factors and cognitive function have been found in younger than older adults. This age pattern may be subject to mortality selection and non-ignorable missingness caused by dropouts due to death, but this remains unclear.

Methods: Longitudinal data from 9,562 adults aged 50 and older from Waves 1-4 (2011-2018) of the China Health and Retirement Longitudinal Study were used.

Background: Although intrinsic capacity (IC) has been constructed in older populations, whether IC retains the same structure over time has not been formally examined, nor have the factors associated with the changes in IC over time been thoroughly investigated. This study aimed to establish that the structure of IC remains unchanged over time by testing its longitudinal measurement invariance and to investigate factors that influence the longitudinal change of IC over time.

Methods: Data came from 7,271 participants aged 60 and older from the China Health and Retirement Longitudinal Study in 2011 (Wave 1) and 2015 (Wave 3).

Article Synopsis
  • Grey divorce and later remarriage show a growing trend in high-income countries, but there's limited research on their mental health effects, particularly regarding non-marital separation and re-partnering later in life.
  • A study using data from over 228,000 individuals in Finland revealed significant increases in antidepressant (AD) use leading up to and after events like divorce, non-marital separation, and bereavement, with women showing larger increases than men.
  • While re-partnering resulted in a small and temporary decrease in AD use, the overall mental health impact of union dissolution remains substantial and persistent, especially among women.

Background And Objectives: Cross-national research on cognitive aging inequality has largely concentrated on Western countries. It is unclear whether socioeconomic position (SEP) has similar effects on cognitive decline in emerging economies. We compared the association between life course SEP and cognitive function trajectories between China and England, the largest nation under state socialism and one of the oldest capitalist countries.

Background: Social support is associated with cognitive function at an older age, but how distinct dimensions of social support affect trajectories of cognitive decline in older Chinese adults remains unclear.

Methods: Using longitudinal data (waves 1-4) from the China Health and Retirement Longitudinal Study, 7-year trajectories of cognitive decline by various social support markers, including family support, financial support, public support and perceived support, were estimated using latent growth curve modelling for adults aged 60 and over (N=6795).

Results: After adjusting for baseline sociodemographics, behaviours, body mass index and health conditions, all social support markers were associated with baseline cognitive function, except for living with spouse.

Background: Stroke incidence has continued to increase recently in most countries. The roles of individual-level income on the incidence of overall stroke and its subtypes are still unknown, especially in low- and middle-income countries and the cross-national evidence is also limited. We explored the association between individual-level income and stroke incidence in Finland and China.

Background: Psychological conditions have been found to be associated with an increased risk of incident benign paroxysmal positional vertigo (BPPV). However, much less is known on whether and how psychological conditions such as anxiety, insomnia and obsessive-compulsive disorder (OCD) affect the recurrence of BPPV.

Methods: A retrospective cohort study of 2,612 outpatients and inpatients diagnosed with BPPV between September 2012 and August 2020.

Background: The possible mediating role of cardiovascular disease (CVD) in the relationship between alcohol use disorders (AUD) and the risk of early-onset (
Methods: Using linked Finnish national register data, a population-based cohort study of 262,703 dementia-free Finnish men and women aged 40 + at baseline (December 31, 1999) was established. AUD and CVD in 1988-2014, and incident dementia in 2000-2014 were identified from Finnish Hospital Discharge Register and/or Drug Reimbursement Register.

Background: It remains unclear how pre-existing depression, anxiety, and diabetes of different durations are associated with the risk of pancreatic cancer, its clinical characteristics, treatment modalities, and subsequent survival.

Methods: From a register-based random sample of Finns residing in Finland at the end of the period 1987-2007, 6492 patients diagnosed with primary pancreatic cancer in 2000-2014, and 32 460 controls matched for birth cohort and sex, were identified. Pre-existing depression, anxiety, and diabetes were ascertained from the records of prescribed medication purchases.

Background: Cognitive reserve (CR) could partly explain the individual heterogeneity in cognitive decline. No study measured CR from a life course perspective and investigated the association between CR and trajectories of cognitive decline in older Chinese adults.

Methods: Data of 6795 Chinese adults aged 60+ from China Health and Retirement Longitudinal Study were used.

Background: There is mixed evidence on the association between living arrangements and mid-late life cognition, which may be due to distinct familial arrangements and preferences between populations. To address such heterogeneity, we assessed these associations in China and England.

Methods: Four-year trajectories of episodic memory scores (0-20, word recall test) by living arrangements (living with partner only, living with partner and children/grandchildren, living with no partner but with children/grandchildren, and living alone) were estimated using latent growth curve modelling for men and women aged 50+ from China (n=12 801) and England (n=10 964).

Background: The association between childhood adversity and an individual's health in later life has been extensively studied in Western societies; however, little is known about this association for the development of multimorbidity in China.

Methods: Three waves (2011-2012, 2013 and 2015) of the China Health and Retirement Longitudinal Study were used for adults aged 45-101 years. Multimorbidity was assessed by the summed scores of self-reported physician diagnoses of 14 chronic diseases.

Background: Previous research has shown that certain living arrangements, such as living alone, are associated with worse health at older ages. We assessed the association between living arrangements and hospital care use among middle-aged and older adults, and investigated to what extent observed and unobserved individual characteristics explain this association.

Methods: Longitudinal Finnish registry data for men and women aged 50-89 years were used for the period 1987-2007.

Background: Despite the growing prevalence of depression in the Chinese elderly, there is conflicting evidence of life course socioeconomic position (SEP) and depression onset in China, and whether this association is akin to that observed in Western societies. We compared incident risk of mid-late life depression by childhood and adulthood SEP in China and England, a country where mental health inequality is firmly established.

Methods: Depression-free participants from the China Health and Retirement Longitudinal Study (N=8508) and the English Longitudinal Study of Ageing (N=6184) were studied over 4 years.

A number of studies have established the link between childhood adversity (CA) and depression across the life span. This association can be culturally specific, and it remains unclear whether and how different aspects of CA affect depressive symptoms in later life in non-Western societies. Data were from the China Health and Retirement Longitudinal Study in 2011, 2013, 2014 (Life Event History survey) and 2015 (N = 13,710).

Background: Unhealthy diet may increase the risk of impaired physical functioning in older age. Although poor diet and limited physical functioning both seem to be particularly common in Eastern Europe, no previous study has assessed the relationship between these two factors in this region. The current analysis examined the association between overall diet quality and physical functioning in Eastern European populations.
