Association of Plastic Exposure with Cognitive Function Among Chinese Older Adults.

Background: The widespread exposure to plastic products and the increasing number of individuals with cognitive impairments have imposed a heavy burden on society.

Objective: This study aims to investigate the relationship between plastic product exposure in daily life and cognitive function in older Chinese individuals.

Methods: Data were obtained from the 2023 Ningxia Older Psychological Health Cohort, comprising 4045 participants aged 60 and above.

Health impacts of lifestyle and ambient air pollution patterns on all-cause mortality: a UK Biobank cohort study.

Background: Extensive evidence indicates that both lifestyle factors and air pollution are strongly associated with all-cause mortality. However, little studies in this field have integrated these two factors in order to examine their relationship with mortality and explore potential interactions.

Methods: A cohort of 271,075 participants from the UK Biobank underwent analysis.

Hidden dangers: Does multisensory impairments accompanying visual impairment increase dementia risk.

Background: Growing evidence suggests that sensory impairment, particularly in the form of visual impairment, may contribute to the development of dementia. However, it remains unclear whether experiencing concurrent visual impairment in combination with other types of multisensory impairments may further increase this risk.

Methods: The study used data from the UK Biobank cohort study, which recruited 500,000 adults.

The association between urbanization and adolescent depression in China.

Background: With the rapid urbanization in many countries, more attention is being paid to the relationship between urbanization and mental health, especially depression. However, in countries with rapid urbanization, few empirical studies exist on the relationship between urbanization and adolescent depression.

Methods: Nationally representative survey data from the China Family Panel Studies in 2012, 2016 and 2018 were used.

Effects of thermal exposure to disposable plastic tableware on human gut microbiota and metabolites: A quasi-experimental study.

The aim of this quasi-experimental study was to determine the alterations in gut microbiota and metabolism in humans who consume hot food served in disposable plastic tableware (DPT). Participants in the exposure and control groups were provided three hot meals in DPT (n = 30) or non-DPT (n = 30), respectively. After a month of observation, individuals in the exposure group discontinued the three meals provided in DPT (n = 27) for 1 month as the post-exposure group.

Association of living arrangements with all-cause mortality among older adults: a propensity score-matched cohort study.

Background: Many studies exist on the living arrangements and health status of older adults, but the findings have been inconsistent. Therefore, we examined the relationship between living arrangements and all-cause mortality in older adults.

Methods: This perspective study was based on the Chinese Longitudinal Healthy Longevity Survey (CLHLS) from 2011 to 2018.

Exposure to outdoor artificial light at night increases risk and burden of metabolic disease in Ningxia, China.

Nearly a quarter of the world's land has already been polluted by artificial light. And numerous human and animal studies have corroborated that light at night can disrupt metabolism. Therefore, we aimed to estimate the association between outdoor artificial light at night (ALAN) and the presence of metabolic disease.

Secular trend of non-communicable chronic disease prevalence throughout the life span who endured Chinese Great Famine (1959-1961).

Background: Famine is a risk factor for non-communicable chronic diseases (NCDs), which account for over 80% of deaths in China. The effect of famine on the prevalence of NCDs in terms of various age groups, time periods and cohorts is currently poorly understood.

Objective: This study aims to explore long-term trends in the impact of China's Great Famine (1959-1961) on NCDs in China.

Effects of common plastic products heat exposure on cognition: Mediated by gut microbiota.

Considering plastic exposure patterns in modern society, the effects of exposure to leachate from boiled-water treated plastic products on cognitive function was probed in mice through changes in gut microbiota diversity. In this study, Institute for Cancer Research (ICR) mice were used to establish drinking water exposure models of three popular kinds of plastic products, including non-woven tea bags, food-grade plastic bags and disposable paper cups. 16S rRNA was used to detect changes in the gut microbiota of mice.

Association between reading and depression in Chinese adults.

Qualitative evidences have shown that having the habit of reading might be beneficial for mental health. The present study aims to examine the relationship between reading and depression. National cross-sectional survey data of adults aged >40 years in mainland China were used.

A predictive model for the risk of cognitive impairment in community middle-aged and older adults.

Identifying individuals at high risk of cognitive impairment is essential for treatment and prevention strategies. We aimed to develop and validate a prediction model for evaluating the risk of cognitive impairment. Data were from the China Family Panel Studies (CFPS) and China Health and Retirement Longitudinal Study (CHARLS).

Association between changes in social capital and mental well-being among older people in China.

Background: The mental well-being of older people has become social concern under aging times in China. Social capital has been linked to mental well-being. Our aims were to explore how social capital and the state of mental well-being of older people were changing and what the relationship between them was.

Effects of oral exposure to leachate from boiled-water treated plastic products on gut microbiome and metabolomics.

By simulating plastic exposure patterns in modern society, the impact of daily exposure to plastic products on mammals was explored. In this study, Institute for Cancer Research (ICR) mice were used to establish drinking water exposure models of three popular kinds of plastic products, including non-woven tea bags, food-grade plastic bags and disposable paper cups. Feces and urine of mice were collected for gut microbiome and metabolomics analysis.

Happiness, depression, physical activity and cognition among the middle and old-aged population in China: a conditional process analysis.

Background: Happiness is one variable of subjective well-being, which has been increasingly shown to have protective effects on health. Although the association between happiness and cognition has been established, the mechanism by which happiness leads to cognition remains unclear. Since happiness, depression, and physical activity may all be related to cognition, and happiness is related to depression and physical activity, this study explored the effect of depression and physical activity on the relationship between happiness and cognition among middle and old-aged individuals in China.

Association of outdoor artificial light at night with mental health among China adults: a prospective ecology study.

Multiple environmental changes are related to mental disorders. However, research on the association between artificial light at night (ALAN) and mental health in China is limited, particularly at the national level. We used a "difference-in-differences" design and logistic regression to explore the relationship between ALAN changes and scores on self-assessed mental health.
