Cardiorespiratory Fitness and All-Cause Mortality in Women with Metabolic Syndrome.

To examine the association between cardiorespiratory fitness (fitness) and all-cause mortality in women with metabolic syndrome (MetSyn). The sample included 1798 women with MetSyn (mean age 50.2 years) who received a comprehensive preventive baseline examination between 1978 and 2016, with mortality follow-up through December 31, 2017.

Mechanisms of an App-Based Physical Activity Intervention and Maintenance in Community-Dwelling Women: Mediation Analyses of a Randomized Controlled Trial.

Background: Understanding the mechanism of interventions that increase physical activity (PA) is critical to developing robust intervention strategies.

Aims: This study aims to examine the mediation effects of hypothesized changes in self-efficacy, social support, and barriers on daily changes in accelerometer-measured steps and the duration of moderate to vigorous PA over 3-month intervention and 6-month maintenance periods with a mobile phone-based PA education program.

Methods: Data were analyzed for a total of 210 physically inactive women who were randomized.

Physical Activity, Adiposity, and Serum Vitamin D Levels in Healthy Women: The Cooper Center Longitudinal Study.

Although physical inactivity, obesity, and low serum vitamin D [25-hydroxyvitamin D, 25(OH)D] are common among women, joint associations among these biomarkers are not well-described. A total of 7553 healthy women received a comprehensive examination (2006-2018), including self-reported physical activity (PA), body mass index (BMI), waist circumference (WC), waist:height ratio (W:HT), percent body fat (%Fat), and 25(OH)D. Participants were divided into four categories of PA based on current guidelines: <500 (not meeting guidelines), 500-1000 (meeting guidelines), 1001-2500 (>1-2.

Cardiorespiratory fitness, white blood cell count, and mortality in men and women.

Background: We examined the associations of cardiorespiratory fitness (CRF) and white blood cell count (WBC) with mortality outcomes.

Methods: A total of 52,056 apparently healthy adults completed a comprehensive health examination, including a maximal treadmill test and blood chemistry analyses. CRF was categorized as high, moderate, or low by age and sex; WBC was categorized as sex-specific quartiles.

Sitting Time, Physical Activity, and Cognitive Impairment in Midlife and Older Adults.

This study cross-sectionally examines the relations of sitting and physical activity (PA) with cognitive impairment in community-dwelling adults aged 55-87 years (n = 3,780). Multivariable logistic regression assessed independent and joint relations of sitting and PA with Montreal Cognitive Assessment scores adjusting for covariates. Sitting ≥75% of the time and not meeting PA guidelines were related to 60% (95% confidence interval [CI] [1.
