Longitudinal health behaviour patterns among adults aged ≥50 years in China and their associations with trajectories of depressive symptoms.

Objectives: Against the background of the growing recognition of the need for a holistic perspective on health behaviour, we aim to identify longitudinal patterns of multiple health behaviours, and to assess associations of such patterns with depressive symptoms among older people in China.

Methods: Using three waves of China Health and Retirement Longitudinal Study data ( = 8439), we performed latent class growth analyses (LCGAs) to identify longitudinal patterns of multiple health behaviours. Random-effects models were estimated to assess associations between health behaviour patterns and depressive symptoms.

Associations of Social Cohesion and Socioeconomic Status with Health Behaviours among Middle-Aged and Older Chinese People.

: An understanding of factors associated with health behaviours is critical for the design of appropriate health promotion programmes. Important influences of social cohesion, education, and income on people's health behaviours have been recognised in Western countries. However, little is known about these influences in the older Chinese population.

The longitudinal relationship between income and social participation among Chinese older people.

The vital role of active social participation in older people's lives is widely acknowledged. The maintenance of adequate levels of social participation is an essential element of successful aging. Low income may inhibit older people from engaging in social activities.

A healthy diet and physical activity are important to promote healthy ageing among older Chinese people.

Objective: To examine the associations between multiple health behaviours and health outcomes among older Chinese adults.

Methods: Data from the World Health Organization’s Study on global AGEing and adult health Wave 1 (2007–2010), collected among the older Chinese population, were included in this study. Smoking, diet, and physical activity were analysed by linear regression for any associations with depressive symptoms, quality of life (QoL), cognitive function, and physical function.

How Prevalent Are Implausible EQ-5D-5L Health States and How Do They Affect Valuation? A Study Combining Quantitative and Qualitative Evidence.

Background: When designing a valuation study, a criterion that has been used for selecting health states for direct valuation is whether the health states are plausible for respondents, because it is assumed that inclusion of implausible states would compromise data quality.

Objectives: To understand which health states are implausible, and how their values differ from the values of the plausible counterparts.

Methods: One thousand six hundred Chinese students valued all 3125 health states of the 5-level EuroQol 5-dimensional questionnaire (EQ-5D-5L) using the EuroQol visual analogue scale.

Risk factors and protective factors associated with incident or increase of frailty among community-dwelling older adults: A systematic review of longitudinal studies.

Introduction: Frailty is one of the greatest challenges facing our aging population, as it can lead to adverse outcomes such as institutionalization, hospitalization, and mortality. However, the factors that are associated with frailty are poorly understood. We performed a systematic review of longitudinal studies in order to identify the sociodemographic, physical, biological, lifestyle-related, and psychological risk or protective factors that are associated with frailty among community-dwelling older adults.

Higher Incidence of Deteriorated Mental Health in Older People Being Mistakenly Labeled as Dementia: A Two-Year Consecutive Community-Dwelling Study in Shanghai, China.

Dementia has been increasingly paid attention by policymakers in China. However, the majority of the public has an indistinct concept of dementia and its diagnostic criteria. Therefore, many abnormal characteristics and actions of older people are labeled as having dementia while diagnosed without dementia.
