Abstract Background Youth use different forms of screen time (e.g., streaming, gaming) that may be related to body mass index (BMI). Screen is non-independent from other behaviors, including physical activity and sleep duration. Statistical approaches such as isotemporal substitution or compositional data analysis (CoDA) can model associations between these behaviors health outcomes. Few studies have examined types time, activity, duration simultaneously in relation BMI. Methods Data were...

Introduction: Current physical activity (PA) recommendations support replacing time spent sedentary with PA of any intensity. Replacing light intensity (LPA) may be a more accessible behavior change for many individuals compared increasing moderate/vigorous (MVPA). However, the longitudinal associations LPA and cardiometabolic health are not clear. Hypothesis: We hypothesized that is associated improvement in risk across midlife. Methods: Participants CARDIA study accelerometer biomarker...

Introduction: Adolescence is characterized by reductions in daily physical activity and nightly sleep, which may increase the risk for worse cardiometabolic health. This study examined associations of 24-hour movement behaviors (24h MBs), including (PA), sedentary behavior, with BMI among adolescents Future Families Child Wellbeing Study (FFCWS). Methods: Data included 371 (15.4±0.5 years; 46% non-Hispanic Black; 53% female) from age 15 FFCWS sleep sub-study. was calculated using height...

Introduction: Heart failure (HF) morbidity and mortality are disparately greater among Black individuals compared with their peers from other racial ethnic backgrounds. Sleep, physical activity (PA), sedentary behavior (SB) each associated incident HF, but these interdependent behaviors, integration of exposures is needed to best understand the holistic risk for HF. Therefore, we examined association between 24-hour compositional distribution behaviors including HF subtypes (i.e., preserved...

Purpose : Current in-school physical activity (PA) policies lack regulation, which testifies to the urgency of monitoring moderate vigorous PA (MVPA). This study quantifies demographical differences among elementary students. Methods Fourth-grade students wore accelerometers during school for 1 week. The teachers logged information setting and duration opportunity. Results accelerometry data ( N = 148) showed alarming results in MVPA opportunity times. Significant sex boys accumulate more...

Background: The Physical Activity Guidelines 2nd Edition recommends ≥2 days of resistance training (RT). Evidence supports a dose-response relation between RT volume and cardiometabolic health. We examined whether guidelines were associated with lower all-cause mortality. Methods: Participants from the 1999-2006 NHANES cycles (N = 5855) self-reported past 30 physical activity including number sessions, average session duration in minutes, type. Mortality was ascertained linked National Death...

Introduction: Body mass index (BMI) and waist circumference (WC) capture related but distinct measures of adiposity (overall vs central adiposity). It is unclear if changes in WC are associated with incident diabetes mellitus (DM) whether the relation similar between BMI groups. Methods: We included 3,234 CARDIA participants (61% Black, 63% females, mean age 24.7 [3.7] years at baseline) without prevalent DM from baseline (1985-1986) through exam Year 20 (Y20; 2005-2006). Incident after Y20...

Vascular aging, a precursor of arterial stiffness, is associated with neurocognitive impairment (NCI) and cardiovascular disease. Although HIV rapid vascular it unknown whether stiffness mediates changes in cognitive function. We explored estimated markers aging were NCI indices HIV-positive individuals.

Objective: To investigate differences between a controlled and non-controlled exercise modality when walking running at self-selected pace. Methods: Male female participants (N=30, 21.07±0.88 years of age) engaged in four sessions testing V̇O2max, one-mile walk run on an indoor track, laboratory treadmill. With significance level set p<0.05, the following results were found. Results: Walking heart rate rating perceived exertion significantly higher treadmill compared to track (p<0.05)....

Background: Sedentary behavior (SB), physical activity (PA), and metabolic syndrome (MetS) are risk indicators for cardiometabolic diseases. Novel methods researching MetS by the 16 unique clusters (i.e., WC+FBG+BP) as a continuous severity z-score (MetS-Z) have emerged. This study examined how SB, PA, MetS-Z differed among SB PA differences tertiles. Methods: Using 2015-2016 National Health Nutritional Examination Survey (NHANES) data, participants with (N = 792) were identified....

PURPOSE: Schools provide ample opportunity to address physical inactivity patterns, which have been established as a crucial risk factor of health concerns. As evidence associations between morbidity and progression childhood obesity adult expand along with the inverse relationship school year activity (PA), an urgency remains for schools implement mandatory policies addressing accumulated moderate-to-vigorous (MVPA) per week. The purpose this study was quantify in-school PA levels among...

Background: Metabolic syndrome (MetS) increases the risk of premature morbidity and mortality. Physical activity (PA) beneficially affects MetS; however, it is unclear if PA types differ among adolescents 12–15 years old, according to their MetS status. This study compared self-reported by Methods: Using 2015–2016 National Health Nutritional Examination Survey (NHANES) data, 664 in past seven days. status was assessed using Ford’s pediatric adaptation ATP-III adult criteria. Pearson...

Introduction: Over the course of 24 hours, humans engage in multiple movement behaviors including sleep, physical activity (PA), and sedentary behavior (SB) that are each associated with high-sensitivity C-reactive protein (hs-CRP). Traditional regression models do not allow for estimation relative contributions these on hs-CRP as they correlated sum to 100% whole day. Compositional isotemporal substitution analyses will us estimate how exchanging one another influences hs-CRP. We...
