Socioeconomic disparities and green space associated with myopia among Chinese school-aged students: A population-based cohort study.

Background: There is increasing evidence on the link between environmental factors and myopia in children and adolescents, yet with inconsistent conclusions. We investigated the associations between socioeconomic inequalities and green space with myopia in school-aged students participating in the Tianjin Child and Adolescent Research of Eye (TCARE) study.

Methods: We obtained data from a population-based dynamic cohort study conducted in Tianjin, China, in 2021 and followed up in 2022.

The association among SES, screen time, and outdoor play in children at different ages: The GECKO Drenthe study.

Introduction: This study examined the association among socioeconomic status (SES), screen time, and outdoor play in children at different ages in the GECKO Drenthe birth cohort study.

Methods: Valid data were obtained from two surveys at ages 3-4 years and 10-11 years. Screen time (TV watching and computer use) and outdoor play were reported by parents.

Urine podocyte mRNA loss in preterm infants and related perinatal risk factors.

Background: Preterm birth has been identified as a risk factor for development of long-term chronic kidney disease. Podocyte loss has been reported to contribute to this process in preterm animal models. However, details about podocyte loss in preterm infants and related perinatal risk factors have not been well clarified.

The Association Between Sedentary Screen Time, Non-screen-based Sedentary Time, and Overweight in Chinese Preschool Children: A Cross-Sectional Study.

Less is known about the effects of the different domains of sedentary behaviors on healthy weight in young children. This cross-sectional study examined the association between sedentary screen time (SST), non-screen-based sedentary time (NSST), and overweight (and obesity) in Chinese preschoolers. Data were collected from the Physical Activity and Health in Tianjin Chinese Children study (PATH-CC), involving healthy children 3-6 years old and their families.

Environmental correlates of sedentary behaviors and physical activity in Chinese preschool children: A cross-sectional study.

Objective: This cross-sectional study examined environmental correlates of sedentary behavior (SB) and physical activity (PA) in preschool children in the urban area of Tianjin, China.

Methods: Data were collected from the Physical Activity and Health in Tianjin Chinese Children study, involving healthy children 3-6 years old and their families. In all children (n = 980), leisure-time SB (LTSB) and leisure-time PA (LTPA) were reported in min/day by parents.

Physical activity around the clock: objectively measured activity patterns in young children of the GECKO Drenthe cohort.

Background: Given the widespread problem of physical inactivity, and the continued growth in prevalence of childhood and adolescent obesity, promotion of regular physical activity (PA) among young people has become a public priority. A greater understanding of children's PA patterns throughout the day is needed to effectively encourage children to be more physically active. Hence this study looking at the distribution of PA in young children throughout the day and its relevance to overweight.

Objectively measured physical activity and psychosocial functioning in young children: The GECKO Drenthe cohort.

The global trend in inactivity in children may be related to psychosocial problems. We investigated the cross-sectional association between physical activity (PA) levels and psychosocial functioning in 3.4-7.

Environmental correlates of sedentary time and physical activity in preschool children living in a relatively rural setting in the Netherlands: a cross-sectional analysis of the GECKO Drenthe cohort.

Objectives: This study examined the relationship between environmental correlates and children's sedentary time (ST), light physical activity (LPA) and moderate-to-vigorous physical activity (MVPA) in preschool children.

Design: Cross-sectional study SETTING: A birth cohort in Drenthe, a northern province and relatively rural area of the Netherlands.

Participants: Valid data both for the ActiGraph and the questionnaire were obtained from 505 child-parent pairs.

Factors of physical activity among Chinese children and adolescents: a systematic review.

Background: Lack of physical activity is a growing problem in China, due to the fast economic development and changing living environment over the past two decades. The aim of this review is to summarize the factors related to physical activity in Chinese children and adolescents during this distinct period of development.

Methods: A systematic search was finished on Jan 10, 2017, and identified 2200 hits through PubMed and Web of Science.
