Insulin resistance mediates the association between physical activity and mortality in US adults with metabolic syndrome.

This study examines the associations between physical activity (PA) and all-cause mortality (ACM), cause-specific mortality (cancer, cardiovascular disease), and premature mortality, with a focus on the mediating role of insulin resistance. Data from the National Health and Nutrition Examination Survey (NHANES) were analyzed, including 8,460 participants. PA was quantified in metabolic equivalents (MET-h/week) and categorized into four groups: no physical activity (NOPA), low-level PA (LLPA), moderate-level PA (MLPA), and high-level PA (HLPA).

Correlates of Meeting the Muscle-Strengthening Exercise Guidelines in Children and Adolescent.

This study aimed to explore the potential correlates of muscle-strengthening exercise (MSE) in Chinese children and adolescents. A convenient sample ( = 3733) was recruited into this study. Self-reported questionnaires were used to collect information on sex, grade, ethnicity, residence, family composition, moderate to vigorous physical activity (MVPA), family income, parent's education level and MSE in children and adolescents as well as their parent(s).

The Associations of Active Travel to School With Physical Activity and Screen Time Among Adolescents: Do Individual and Parental Characteristics Matter?

Little is known about the relationship of active travel to school (ATS) with physical activity (PA) and screen time (ST) by individual and parental characteristics among adolescents, especially in China. To address the research gap, this study aimed to explore the difference of sex, age, living environment, parental occupation and education level in the relationship of ATS with PA and ST among students of grades 7-12 (aged 10-18 years) using cross-sectional data. In 13 cities of Hubei province, China, students from 39 public schools were recruited to engage in the survey.

Muscle-Strengthening Activities and Sociodemographic Correlates among Adults: Findings from Samples in Mainland China.

A growing body of research has investigated the level of participation in muscle-strengthening (MS) activities and their correlates among Western populations; however, scarce attention has been paid to this issue among Chinese adults. This study aimed to describe the level of MS activities and to explore the relationships between sociodemographic correlates and level of MS activities in a large sample of Chinese adults. For this study, 3073 adults were recruited from 13 cities in Hubei Province.
