Grip strength, genetic predisposition, and Incident Parkinson's disease: a prospective cohort study in the UK Biobank.

To examine the association and modifiable risk factors between grip strength (GS) and Parkinson's disease (PD) incidence considering genetic factors, a total of 411,648 individuals without PD at baseline from the UK Biobank were included. GS was measured by a hydraulic dynamometer. The polygenic risk score assessed the genetic predisposition.

The joint associations of physical activity and ultra-processed food consumption with depression: A cohort study in the UK Biobank.

Background: Despite substantial evidence regarding independent associations between physical activity (PA) and ultra-processed foods (UPF) consumption with depression, the joint effects of these two factors remain unknown.

Methods: This study included 99,126 participants without depression in the UK Biobank at baseline. A 24-h recall method was used to assess UPF consumption, and self-reported total physical activity (TPA), moderate-to-vigorous physical activity (MVPA), and vigorous physical activity (VPA) were assessed by metabolic equivalent task (MET).

Replacement of sedentary behavior with various physical activities and the risk of incident depression: a prospective analysis of accelerator-measured and self-reported UK Biobank data.

Purpose: To examine the dose‒response relationships of sedentary behavior (SB) and physical activities (PAs) with depression, and to explore the effects of replacing SB with PAs on depression risk.

Methods: The study used data from UK Biobank aged 37 to 73 years. Light physical activity (LPA), moderate-to-vigorous activity (MVPA), sleep duration, and total sedentary behavior (TSB) were measured by accelerometers.

Associations and Mediating Pathways Between Childhood Adversity and Risk of Dementia: A Cohort Study in the UK Biobank.

Background: While childhood adversity (CA) is known to be associated with multiple adverse outcomes, its link with dementia is an area with limited exploration and inconsistent agreement. The study aimed to examine the longitudinal associations of CA with incident all-cause dementia and to quantify the potential mediating pathways.

Methods: Data from the UK Biobank.

Association and biological pathways between lung function and incident depression: a prospective cohort study of 280,032 participants.

Background: Lung health is increasingly recognized as an essential factor in mental health. However, prospective evidence on lung function with incident depression remains to be determined. The study aimed to examine the prospective association between impaired lung function and incident depression and the underlying biological mechanisms.

Explaining how childhood physical abuse and physical neglect influence adult depression: An analysis with multiple sequential mediators.

Background: Substantial evidence indicates that experiencing physical abuse and neglect during childhood significantly elevates the likelihood of developing depression in adulthood. Nevertheless, there remains a dearth of understanding regarding the mechanisms underpinning this correlation.

Objective: In this study, we aimed to examine the associations of childhood physical abuse and physical neglect with depression using follow-up data from UK Biobank and quantified the contribution of smoking, insomnia, and BMI in these associations.

Exposure to residential green and blue space and the natural environment is associated with a lower incidence of psychiatric disorders in middle-aged and older adults: findings from the UK Biobank.

Background: There is increasing evidence for the role of environmental factors and exposure to the natural environment on a wide range of health outcomes. Whether exposure to green space, blue space, and the natural environment (GBN) is associated with risk of psychiatric disorders in middle-aged and older adults has not been prospectively examined.

Methods: Longitudinal data from the UK biobank was used.

Prevalence and Associated Factors of Premenstrual Syndrome in Chinese Adolescent Girls.

Epidemiological data on premenstrual syndrome (PMS) in Chinese adolescents are limited. This study reported the prevalence and associated factors of PMS in a large sample of Chinese adolescents. A total of 5099 adolescent girls who had menarche participated in the baseline survey of Shandong Adolescent Behavior and Health Cohort study in Shandong, China.

Temporal and spatial trends in road traffic fatalities from 2001 to 2019 in Shandong Province, China.

Objective: This study explored the temporal and spatial trends in road traffic fatalities in Shandong Province from 2001 to 2019 and discusses the possible influencing factors.

Methods: We collected data from the statistical yearbooks of the China National Bureau of Statistics and the Shandong Provincial Bureau of Statistics. Join-point Regression Program 4.

Starting a Romantic Relationship, Breakups, and Sleep: A Longitudinal Study of Chinese Adolescents.

Background: Epidemiological data on the association between romantic experiences and sleep in adolescents are limited. This study examined the associations of starting a romantic relationship (SRR) and romantic breakups with insomnia symptoms and sleep duration in adolescents.

Methods: A total of 7,072 Chinese adolescents were surveyed in November-December 2015 and 1 year later.

The associations of physical activity and lifetime depression with all-cause and cause-specific mortality: evidence from a prospective cohort study.

This study aims to explore the joint associations of physical activity and lifetime depression with all-cause and cause-specific mortality. The present study using data from UK Biobank, included 316568 participants aged 37 to 73 years recruited from 22 centers between 2006 and 2010. Total physical activity (TPA), moderate-to-vigorous physical activity (MVPA) and vigorous physical activity (VPA), assessed by metabolic equivalent task (MET) were used and Cox-proportional hazard models were performed in this study.

Internalizing and externalizing problems mediate the relationship between maltreatment and self-harm among UK adolescents.

Background: Maltreatment is a significant predictive factor for self-harm in adolescents. Internalizing and externalizing problems are both common psychopathological issues in adolescents. This study aimed to look into the link between maltreatment and self-harm in a large sample of adolescents in the UK, as well as the mediating effects that internalizing and externalizing problems play in this link.

Shift work schedule and sleep patterns in relation to incident depression: Evidence from a prospective cohort study.

This study aims to explore the joint associations of shift work and sleep patterns with incident depression. The present prospective cohort using data from UK biobank, included 220,651 participants aged 38 to 71 years recruited between 2006 and 2010. Every participant finished a self-completed touch-screen questionnaire.

The associations between DNA methylation and depression: A systematic review and meta-analysis.

Background: Growing evidence suggests that epigenetic modification is vital in biological processes of depression. Findings from studies exploring the associations between DNA methylation and depression have been inconsistent.

Methods: A systematical search of EMBASE, PubMed, Web of Science, and PsycINFO databases was conducted to include studies focusing on the associations between DNA methylation and depression (up to November 1st 2021) according to PRISMA guidelines with registration in PROSPERO (CRD42021288664).

Life stress, insomnia, and anxiety/depressive symptoms in adolescents: A three-wave longitudinal study.

Purpose: Life stress has negative impacts on sleep and mental health. Little empirical work has investigated the associations between life stress, insomnia, and anxiety/depressive symptoms (ADS) in multi-wave longitudinal studies. This longitudinal study examined these associations in a large sample of adolescents.
