Movement Behavior and Health Outcomes among Sedentary Adults: A Cross-Sectional Study.

Sedentary behavior, which is highly prevalent among office workers, is associated with multiple health disorders, including those of the musculoskeletal and cardiometabolic systems. Although prior studies looked at postures or physical activity during work or leisure time, few analyzed both posture and movement throughout the entire day. This cross-sectional pilot study examined the movement behavior of sedentary office workers during both work and leisure time to explore its association with musculoskeletal discomfort (MSD) and cardiometabolic health indicators. Twenty-six participants completed a survey and wore a thigh-based inertial measuring unit (IMU) to quantify the time spent in different postures, the number of transitions between postures, and the step count during work and leisure time. A heart rate monitor and ambulatory blood pressure cuff were worn to quantify cardiometabolic measures. The associations between movement behavior, MSD, and cardiometabolic health indicators were evaluated. The number of transitions differed significantly between those with and without MSD. Correlations were found between MSD, time spent sitting, and posture transitions. Posture transitions had negative correlations with body mass index and heart rate. Although no single behavior was highly correlated with health outcomes, these correlations suggest that a combination of increasing standing time, walking time, and the number of transitions between postures during both work and leisure time was associated with positive musculoskeletal and cardiometabolic health indicators among sedentary office workers and should be considered in future research.

Abstract P269: Associations Between Neighborhood Socioeconomic Deprivation During Pregnancy and Offspring Early Anthropometric Outcomes

Introduction: Residing in areas with lower neighborhood socioeconomic position (NSEP) is associated with adverse birth outcomes like small for gestational age and low birthweight. Lower NSEP is also associated with higher weight status and blood pressure in adolescence. However, few studies have assessed NSEP and indicators of cardiometabolic health in early childhood. We examined associations between NSEP during gestation and changes in early childhood weight in a North Carolina (NC) birth cohort. Hypothesis: We hypothesized that lower gestational NSEP would associate with rapid infant weight gain and increased odds of having overweight in early childhood. Methods: The sample was from the Newborn Epigenetics STudy (NEST) cohort. 2,681 gestational parent-offspring pairs were recruited from prenatal visits at obstetrics care facilities in Durham County, NC and enrolled between 2005-2011. For this study, offspring were assessed at birth (N=1,058), 6 months (N=1,268), 1 year (N=1,268), 2 years (N=1,033), and 3 years (N=1,038). NSEP was measured as Neighborhood Deprivation Index (NDI) tertiles at the 2010 US census block group level in NC using parent residential address at enrollment (high NDI=low NSEP). Offspring anthropometric outcomes included: (1) having vs not having overweight (weight for length or body mass index percentiles ≥85 th ) at each study visit; and (2) having rapid vs non-rapid infant weight gain from birth to 6 months and birth to 1 year. Multilevel logistic regression models estimated odds ratios (OR) and 95% confidence intervals (CI) for the relationship between NDI (ref=low) and weight, adjusting for gestational parent age, race, marital status, and education. Results: On average, gestational parents were 28 years old with college degrees (35%), followed by high school or equivalent (22%), and identifying as non-Hispanic (NH) Black (43%), followed by NH White (34%). Prior to covariate adjustment, children residing in neighborhoods with high vs low NDI had greater odds of having overweight at 6 months (OR=1.57, 95% CI=1.10-2.25), 1 year (OR=2.01, 95% CI=1.49-2.71), 2 years (OR=1.78, 95% CI=1.25-2.49), and 3 years (OR=1.35, 95% CI=0.96-1.89) and of experiencing rapid infant weight gain from birth to 6 months (OR=1.03, 95% CI=0.79-1.33) and to 1 year (OR=1.62, 95% CI=1.25-2.09). Associations were attenuated after adjustment, but children residing in neighborhoods with high vs low NDI had greater odds of having overweight at 1 year (OR=1.53, 95% CI=1.09-2.15). Conclusions: Low NSEP may associate with higher early childhood weight. This has important implications for later developmental milestones and health outcomes in childhood. Several potential mechanisms could explain this association, including biological programming and limited neighborhood opportunities for movement and healthy eating. Future work exploring these and other mechanisms is warranted.

An Assessment of Mushroom Consumption on Cardiometabolic Disease Risk Factors and Morbidities in Humans: A Systematic Review.

Mushrooms, unique edible fungi, contain several essential nutrients and bioactive compounds which may positively influence cardiometabolic health. Despite a long history of consumption, the health benefits of mushrooms are not well documented. We conducted a systematic review to assess the effects of and associations between mushroom consumption and cardiometabolic disease (CMD)-related risk factors and morbidities/mortality. We identified 22 articles (11 experimental and 11 observational) from five databases meeting our inclusion criteria. Limited evidence from experimental research suggests mushroom consumption improves serum/plasma triglycerides and hs-CRP, but not other lipids, lipoproteins, measures of glucose control (fasting glucose and HbA1c), or blood pressure. Limited evidence from observational research (seven of 11 articles with a posteriori assessments) suggests no association between mushroom consumption and fasting blood total or LDL cholesterol, glucose, or morbidity/mortality from cardiovascular disease, coronary heart disease, or type 2 diabetes mellitus. Other CMD health outcomes were deemed either inconsistent (blood pressure, HDL cholesterol, and triglycerides) or insufficient (HbA1c/hyperglycemia, hs-CRP, cerebrovascular disease, and stroke). The majority of the articles vetted were rated "poor" using the NHLBI study quality assessment tool due to study methodology and/or poor reporting issues. While new, high-quality experimental and observational research is warranted, limited experimental findings suggest greater mushroom consumption lowers blood triglycerides and hs-CRP, indices of cardiometabolic health.

The effects of lifestyle change on indicators of cardiometabolic health in semi-nomadic pastoralists.

Non-communicable disease risk and the epidemic of cardiometabolic diseases continue to grow across the expanding industrialized world. Probing the relationships between evolved human physiology and modern socioecological conditions is central to understanding this health crisis. Therefore, we investigated the relationships between increased market access, shifting subsistence patterns and cardiometabolic health indicators within Daasanach semi-nomadic pastoralists who vary in their engagement in traditional lifestyle and emerging market behaviors. We conducted cross-sectional socioecological, demographic and lifestyle stressor surveys along with health, biomarker and nutrition examinations among 225 (51.6% female) Daasanach adults in 2019-2020. We used linear mixed-effects models to test how differing levels of engagement in market integration and traditional subsistence activities related to blood pressure (BP), body composition and blood chemistry. We found that systolic and diastolic BP, as well as the probability of having high BP (hypertension), were negatively associated with distance to market, a proxy for market integration. Additionally, body composition varied significantly by socioeconomic status (SES), with significant positive associations between BMI and body fat and higher SES among adults. While evidence for evolutionary mismatch and health variation have been found across a number of populations affected by an urban/rural divide, these results demonstrate the effects of market integration and sedentarization on cardiometabolic health associated with the early stages of lifestyle changes. Our findings provide evidence for the changes in health when small-scale populations begin the processes of sedentarization and market integration that result from myriad market pressures.

Leisure-time physical activity is more strongly associated with cardiometabolic risk than occupational physical activity: Results from a workplace lifestyle modification program

BackgroundRegular physical activity (PA) plays a key role in the management and prevention of numerous chronic diseases. However, recent studies have suggested that occupational physical activity (OPA) may not always have health benefits. The aim of the present study was to examine the respective contributions of OPA vs. leisure-time physical activity (LTPA) to the variation in the cardiometabolic profile, including cardiorespiratory fitness (CRF), of employees involved in a workplace lifestyle modification program. Our study hypothesis was that LTPA would show a stronger association with indices of cardiometabolic health than OPA. MethodsA mobile health assessment unit was used to assess 5145 workers (3397 men and 1748 women) on site at their workplace. Assessments included lifestyle questionnaires (overall diet quality, type of OPA and level of LTPA), blood pressure measurements, blood tests, anthropometric measurements, and a submaximal treadmill exercise test to assess CRF. Results were adjusted for education, household income and age. ResultsWhen workers were classified on the basis of their OPA (sedentary work, standing work, physical work, and heavy manual work), only a few significant differences in the cardiometabolic profile were observed in men, with those in the physical work category having more favorable values than sedentary workers. However, substantial and significant differences were observed among employees classified on the basis of their LTPA, these differences being observed in both men and women. For instance, waist circumference, the cholesterol/HDL cholesterol ratio, triglyceride concentrations and resting heart rate were lower in active individuals compared to inactive and moderately inactive individuals (p < 0.01). Furthermore, irrespective of whether or not employees were sedentary at work, a high level of LTPA was associated with a greater CRF (p < 0.001). Finally, we found that the lowest prevalence of hypertriglyceridemic waist (p < 0.01) and the highest score of overall diet quality (p < 0.001) were observed in active individuals, irrespective of their OPA category. ConclusionLevels of LTPA were more strongly associated with cardiometabolic health than OPA in a cohort of blue- and white-collar employees. Furthermore, high levels of LTPA were found to counteract the potentially deleterious effects of a sedentary work on cardiometabolic health.

Differences in Sleep Offset Timing between Weekdays and Weekends in 79,161 Adult Participants in the UK Biobank.

Variability in the timing of daily sleep is increasingly recognized as an important factor in sleep and general physical health. One potential driver of such daily variations in sleep timing is different work and social obligations during the "working week" and weekends. To investigate the nature of weekday/weekend differences in the timing of sleep offset, we examined actigraphy records of 79,161 adult participants in the UK Biobank who wore an actiwatch for 1 week. The time of sleep offset was found to be on average 36 min later on weekends than on weekdays, and when this difference was expressed as an absolute value (i.e., irrespective of sleep offset being either later or earlier on weekends), it was 63 min. Younger age, more socioeconomic disadvantage, currently being in employment, being a smoker, being male, being of non-white ethnicity and later chronotype were associated with greater differences in sleep offset between weekdays and weekend days. Greater differences in sleep offset timing were associated with age-independent small differences in cardiometabolic health indicators of BMI and diastolic blood pressure, but not HbA1c or systolic blood pressure. In a subset of participants with Type 2 Diabetes Mellitus, weekday/weekend sleep offset differences were associated weakly with BMI, systolic blood pressure and physical activity. Overall, this study demonstrates potentially substantive differences in sleep offset timings between weekdays and weekends in a large sample of UK adults, and that such differences may have public health implications.

The association between offspring birthweight and future risk of maternal diabetes: A population-based study.

As an indicator of maternal cardiometabolic health, newborn birthweight may be an important predictor of maternal type 2 diabetes mellitus (diabetes). We evaluated the relation between offspring birthweight and onset of maternal diabetes after pregnancy. This retrospective cohort study used linked population-based health databases from Ontario, Canada. We included women aged 16-50 years without pre-pregnancy diabetes, and who had a live birth between 2006 and 2014. We used Cox proportional hazard regression to evaluate the association between age- and sex-standardized offspring birthweight percentile categories and incident maternal diabetes, while adjusting for maternal age, parity, year, ethnicity, gestational diabetes (GDM) and hypertensive disorders of pregnancy (HDP). Results were further stratified by the presence of GDM in the index pregnancy. Of 893,777 eligible participants, 14,329 (1.6%) women were diagnosed with diabetes over a median (IQR) of 4.4 (1.5-7.4) years of follow-up. There was a continuous positive relation between newborn birthweight above the 75th percentile and maternal diabetes. Relative to a birthweight between the 50th and 74.9th percentiles, women whose newborn had a birthweight between the 97th and 100th percentiles had an adjusted hazards ratio (aHR) of diabetes of 2.30 (95% CI 2.16-2.46), including an aHR of 2.01 (95% CI 1.83-2.21) among those with GDM, and 2.59 (2.36-2.84) in those without GDM. A higher offspring birthweight signals an increased risk of maternal diabetes, offering another potentially useful way to identify women especially predisposed to diabetes.

Proteomics, dietary intake, and changes in cardiometabolic health within a behavioral weight-loss intervention: A pilot study.

Identifying associations among circulating proteins, dietary intakes, and clinically relevant indicators of cardiometabolic health during weight loss may elucidate biologically relevant pathways affected by diet, allowing for an incorporation of precision nutrition approaches when designing future interventions. This study hypothesized that plasma proteins would be associated with diet and cardiometabolic health indicators within a behavioral weight-loss intervention. This secondary data analysis included participants (n= 20, mean [SD], age: 40.1 [9.5] years, BMI: 34.2[4.0] kg/m2 ) who completed a 1-year behavioral weight-loss intervention. Cardiovascular disease-related plasma proteins, diet, and cardiometabolic health indicators were evaluated at baseline and 3 months. Associations were determined via linear regression and integrated networks created using Visualization Of LineAr Regression Elements (VOLARE). A total of 16 plasma proteins were associated with ≥1 diet or health indicator at baseline (p< 0.001); changes in 42 proteins were associated with changes in diet or health indicators from baseline to 3 months (p< 0.005). Baseline tumor necrosis factor receptor superfamily member 10C (TNFRSF10C) was associated with intakes of dark green vegetables (r= -0.712), and fatty acid-binding protein 4 (FABP4) was associated with intakes of unsweetened coffee (r= -0.689). Changes in refined-grain intakes were associated with changes in scavenger receptor cysteine-rich type 1 protein M130 (CD163; r= 0.725), interleukin-1 receptor type 1 (IL1R-T1; r= 0.624), insulin (r= 0.656), and triglycerides (r= 0.648). Circulating cardiovascular disease-related proteins were associated with diet and cardiometabolic health indicators prior to and in response to weight loss.

Protein Supplementation Does Not Maximize Adaptations to Low-Volume High-Intensity Interval Training in Sedentary, Healthy Adults: A Placebo-Controlled Double-Blind Randomized Study.

There is ample evidence that specific nutritional strategies can enhance adaptions to resistance and endurance training. However, it is still unclear whether post-session protein supplementation may increase the effects of low-volume high-intensity interval training (LOW-HIIT). We examined the impact of LOW-HIIT combined with protein vs. placebo supplementation on cardiometabolic health indices in sedentary healthy individuals. Forty-seven participants (31.1 ± 8.0 yrs) performed cycle ergometer LOW-HIIT (5–10x1 min at 80–95% maximum heart rate) for eight weeks and randomly received double-blinded 40 g of whey protein (PRO-HIIT, N = 24) or an isocaloric placebo (maltodextrin, PLA-HIIT, N = 23) after each session. The maximum oxygen uptake (VO2max, primary outcome) and several secondary cardiometabolic outcomes were determined pre-/post-intervention. VO2max increased in PRO-HIIT (+2.8 mL/kg/min, p = 0.003) and PLA-HIIT (+3.5 mL/kg/min, p < 0.001). Systolic and diastolic blood pressure decreased in PRO-HIIT (−7/3 mmHg, p < 0.05) and PLA-HIIT (−8/5 mmHg, p < 0.001). Gamma glutamyl transferase (−2 U/L, p = 0.003) decreased in PRO-HIIT and alanine aminotransferase (−3 U/L, p = 0.014) in PLA-HIIT. There were no significant between-group differences in any of the outcome changes. In conclusion, LOW-HIIT improved VO2max and other cardiometabolic markers irrespective of the supplementation condition. Post-session protein supplementation does not seem to provide any additional benefit to LOW-HIIT in improving cardiometabolic health in sedentary healthy individuals.

The Effects of Virtual Reality Tele-exergaming on Cardiometabolic Indicators of Health Among Youth With Cerebral Palsy: Protocol for a Pilot Randomized Controlled Trial.

Youth with cerebral palsy do not have enjoyable, accessible, and scalable exercise options that can empower them to independently maintain their cardiometabolic health. The primary aim is to examine the preliminary efficacy of a 12-week home-based virtual reality tele-exergaming intervention on several indicators of cardiometabolic health in youth with cerebral palsy compared to the wait list control. A secondary aim is to describe feasibility metrics, namely, recruitment, retention, and adherence rates; perceived enjoyment; intervention safety; and management issues. The tertiary aim is to generate a theory that reveals critical behavioral mechanisms of adherence to tele-exergaming. In this parallel group design randomized controlled trial, 34 inactive youths with cerebral palsy are randomly allocated to one of two groups: a group that immediately receives 12 weeks of virtual reality exergaming with tele-physical education or a wait list control group that undergoes their habitual activity for 12 weeks. Participants are recruited from a Children's Hospital and community network. At baseline (week 0), week 6, and week 12, high sensitivity C-reactive protein and blood insulin, hemoglobin A1c, triglycerides, cholesterol, and pressure are measured by the youth and a caregiver at home using a blood spot test kit and blood pressure cuff. They will also self-measure their lung function and body weight using a peak flow meter and bathroom scale, respectively. Collections are supervised by research staff via videoconference. Changes in outcomes are compared between and within groups using exploratory statistical analyses and descriptive statistics. At postintervention or dropout, participants will undergo semistructured interviews to identify behavioral mechanisms that underly participation. Recruitment procedures started in June 2022. All data are expected to be collected by October 2023. Full trial results are expected to be published by February 2024. Secondary analyses of data will be subsequently published. This trial tests an innovative serious exergaming virtual reality program that includes a completely remote enrollment, assessment, and intervention tele-protocol. The knowledge obtained will inform the development of a larger effectiveness trial for improving the health and well-being of youth with cerebral palsy.

Sleep duration irregularity is associated with elevated blood pressure in young adults

ABSTRACT Sleep irregularity (i.e., highly variable sleep patterns) is an emerging risk factor for cardiometabolic disease. Though irregular sleep patterns are common among young adults, the cardiometabolic health (CMH) repercussions of sleep irregularity in this population are unclear. We examined associations between sleep duration and irregularity with measures of CMH in 44 (24 M/20 F, 23 ± 5y, BMI 26 ± 4 kg/m2, blood pressure (BP): 125/71 ± 14/9 mmHg) young adults. Participants wore actigraphy monitors for seven-days and sleep duration irregularity was operationalized as the standard deviation of nightly sleep duration (sleep SD). CMH variables of interest included brachial and aortic BP, arterial stiffness (cf-PWV), augmentation index (AIx75), and fasting blood glucose and lipids. Associations between sleep duration and sleep SD with CMH variables were assessed via correlations adjusted for sex and BMI. Sleep duration generally was not associated with CMH indices. However, sleep SD was associated with brachial systolic (r = 0.433, p = .027) and diastolic BP (r = 0.415, p = .035). Similarly, sleep duration SD was associated with aortic systolic BP (r = 0.447, p = .022). Our findings show that sleep irregularity, but not duration, is associated with higher brachial and central BP in young adults. Abbreviations: AIx75: augmentation index at a heart rate of 75 beats per minute; BP: blood pressure; CMH: cardiometabolic health; cf-PWV: carotid-femoral pulse wave velocity; DXA: dual x-ray absorptiometry; mg/dl: milligrams per deciliter; PWA: pulse wave analysis; PWV: pulse wave velocity; sleep duration SD: standard deviation of nightly sleep duration

0620 Is SVI a Risk Factor for Sleep and Cardiometabolic Health Among Blacks?

Abstract Introduction The Social Vulnerability Index (SVI) is a novel metric that incorporates a multitude of population factors to predict the susceptibility of communities to deleterious effects of disaster, natural hazards, and environmental insult. Studies show socioeconomic status (SES), an important component of SVI, is a risk factor for cardiometabolic disease and sleep quality. Objectives: This study examined the effect of SVI on cardiometabolic and sleep health among Blacks. Methods We utilized harmonized data extracted from two NIH-funded studies enrolling Blacks (i.e., MetSO and PEERS-ED registries). Participants (N=1,497) included New York residents; 65% were male, with a mean(SD) age of 55(±16.2). Data were collected via self-reports (e.g., ARES questionnaire) for sleep quality/duration and cardiometabolic factors (e.g., weight and diet). SVI components included SES, household composition, minority status, and housing type. Mixed-effect logistic regression models were applied, which assessed the effect of SVI and its many subcomponents on each health-related variable of interest. The model was adjusted for age, sex, and education to account for the effects of these factors overlapping in the SVI subcomponents. Results Approximately 81% of the sample population was obese, 37.9% were diabetic, 62.3% had a history of hypertension, and 18.4% with a heart disease. Regarding sleep health, 7.7% suffered from sleep apnea, 66.6% were short sleepers, 6.64% were long sleepers, and 14.2% reported insomnia. They had a mean(SD) sleep time of 5.92(±2.05) hours. “Overall SVI” was associated with hypertension (OR=3.98) and “housing type &amp; transport” was correlated with heart disease (OR=4.44) prior to adjusting the model. Applying the adjusted model, “minority status &amp; language” predicts obesity (OR=5.32). Also, “overall SVI” and “SES” were associated with diabetes (OR=3.26; OR=2.71) and hypertension (OR=4.00; OR=3.95). “Household composition” approaches significance as a predictor for sleep apnea (unadjusted - OR=0.26; adjusted - OR=0.26) despite the relatively low case proportion. Conclusion SVI seems to be a good indicator of cardiometabolic health among Blacks. However, it is likely a poor marker for sleep health in that population, although trends were observed suggesting that it might play an important role. Further studies are necessary to elucidate the role of SVI on sleep health among Blacks. Support (If Any) R01HL142066, R01HL095799, RO1MD004113, R01HL152453

Investigating the Physical and Mental Health Nexus: a Network Analysis of Depression, Cardiometabolic Health, Bone Mass, and Perceived Health Status Among Filipino Domestic Workers.

Migrant domestic workers are vulnerable to physical and mental health problems given the many challenges they experience while working abroad. Using network analysis, this study examined the structure of depression, cardiometabolic health indicators (BMI, waist-hip ratio (WHR), blood pressure, and heart rate), bone mass, and perceived health status in this population. The network model allowed for an examination of central symptoms or symptoms with the most direct connections with other symptoms; bridge symptoms, or symptoms that link two or more communities; and edges, or relationships among symptoms. Cross-sectional data were gathered from 1375 Filipino domestic workers in Macao (SAR), China. Data from a subsample of 510 participants who met a cutoff indicating depression were analyzed. Anthropometric measurements and surveys were used to collect data, which was analyzed using R statistical software. Results showed four community clusters: three communities consisted of at least two depression symptoms each and the fourth community included physical health indicators. Strong edges were formed between BMI-bone mass, psychomotor-concentration, BMI-WHR, and sad mood-anhedonia. The node with the highest expected influence was BMI. There were three bridges: worthlessness, psychomotor difficulties, and concentration difficulties. The link between depression, cardiometabolic indicators, bone mass, and poor perceived health reinforces the need to address multimorbidity within migrant populations. Health promotion interventions that address mental and physical health may improve the health of this population.

Dietary intake and its associated factors among in-school adolescents in Ghana.

Early-life nutrition related experiences may fuel the emergence of obesity and type 2 diabetes in adolescence. The adoption of unhealthy dietary practices early in life is an indicator of adverse cardiometabolic health in adulthood. In-school adolescents' dietary practices in Ghana have not been explored extensively despite increasing levels of obesity in adolescents. This study sought to examine dietary practices, socio-demographic disparities and the factors influencing dietary choices among in-school adolescents in Ghana. A school-based, cross-sectional study was conducted in the Central region of Ghana in 2017. Using multistage sampling procedures, a total of 1,311 in-school adolescents were selected for the study. A modified version of the generic Global School Health Survey questionnaire on dietary practices was adapted and used for data collection. Percentage and frequency counts were used to report on the dietary practices, while Chi-square was used to determine socio-demographic variations in the dietary practices. Binary logistic regression was used to compute the influence of socio-demographic characteristics of respondents on the prevalence of healthy dietary behavior among in-school adolescents. The study revealed the prevalence of healthy dietary practices (49.9%, n = 654) among in-school adolescents in the region. The study also found increased frequency in consumption of soft drinks (93%, n = 1220) and toffees/sweets (90%, n = 1183) among in-school adolescents. However, low intake of breakfast (57%, n = 749) was observed among the adolescents. Significant disparities were observed in relation to gender, age, parental communication, academic performance and geographical location in the dietary practices of in-school adolescents. Furthermore, gender (OR = 1.36, P = 0.007), academic performance (OR = 2.19, P = 0.001) and geographical location (OR = 1.79, P = 0.001) were found to be significantly associated with dietary practices among in-school adolescents in the region. There was low consumption of fruits and vegetables among adolescents. Fruits and vegetables consumption was associated with gender, academic performance and geographical location, and these may be a reflection that knowledge on healthy food choices and availability are important factors influencing dietary choices among in-school adolescents. School health policy interventions aimed at improving nutritional status among adolescents and enhanced fruit and vegetable consumption in the country should take into account the potential benefit of increasing availability of fruits and vegetables in schools, while reducing access to sweets and soft drinks in the schools and communities.

Association of domain-specific physical activity and sedentary behavior with cardiometabolic health among office workers.

Previous studies have reported opposite effects of occupational or non-occupational physical activity (PA) and sedentary behavior (SB) on health outcomes. However, no study has investigated the relationship between domain-specific movement behaviors and cardiometabolic health (CMH) among office workers, considering the compositional nature of time-use data. We investigated the associations of accelerometer-measured PA and SB for each domain (working time, non-working time on workday, and non-workday) with CMH indicators among office workers, using compositional data analysis. This cross-sectional study included 1258Japanese office workers. The time spent on SB, light-intensity PA (LPA), and moderate- to vigorous-intensity PA (MVPA) were assessed using an accelerometer. CMH indicators were retrieved from the annual health check-up data. Compositional multiple linear regression indicated that PA and SB during non-working time on workdays, but not working time or non-workdays, were significantly associated with CMH. In particular, during non-working time, time reallocations from SB to LPA and from SB to MVPA were associated with favorable changes in cardiometabolic risk score and lipid metabolism, respectively. Paradoxically, a greater proportion of LPA during non-working time was associated with favorable diastolic blood pressure (β=1.61; 95% confidence interval [CI]= 0.02, 3.19), whereas occupational LPA was detrimental (β=-2.48; 95% CI=-4.87, -0.09). Our results suggested that reducing SB and increasing PA during non-working time on workdays may be effective for managing CMH among office workers. Future longitudinal studies using compositional data analysis are required to confirm our results.

Bilirubin as an indicator of cardiometabolic health: a cross-sectional analysis in the UK Biobank

BackgroundMildly elevated bilirubin, a by-product of hemoglobin breakdown, might mitigate cardiometabolic risk factors including adiposity, dyslipidemia, and high blood pressure (BP). We investigated the cross-sectional relationship between (total) bilirubin and baseline cardiometabolic risk factors in 467,519 UK Biobank study participants.MethodsWe used multivariable-adjusted linear regression to estimate associations between bilirubin levels and risk factors of cardiometabolic diseases including body mass index (BMI), waist and hip circumferences (WC, HC), waist-to-hip ratio (WHR), fat mass (FM), and trunk FM, and the blood lipids: apolipoprotein A-I (apoA-I), apolipoprotein B (apoB), apoB/apoA-I, lipoprotein (a), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), LDL/HDL, TC/HDL, triglycerides (TG). Log-transformed bilirubin was modelled with restricted cubic splines and predicted mean values with 99% confidence intervals (CI) for each risk marker were estimated, separately. Second, we applied principal component analysis (PCA) for dimension reduction to in turn six anthropometric traits (height, weight, BMI, WC, HC, and WHR) and all above lipids. Last, we estimated associations (99%CI) between bilirubin and three components of the metabolic syndrome, i.e. WC, TG, and BP using logistic regression.ResultsAfter multivariable adjustments, higher levels of bilirubin were inversely associated with indicators of general adiposity (BMI and FM) and of body fat distribution (WC, HC, WHR, and trunk FM) in both men and women. For example, women with mildly elevated bilirubin (95th percentile equal to 15.0 µmol/L), compared to women with low bilirubin (5th percentile equal to 4.5 µmol/L), had on average a 2.0 kg/m2 (99% CI 1.9–2.1) lower BMI. Inverse associations were also observed with dyslipidemia among men and women. For example, mildly elevated bilirubin among men (95th percentile equal to 19.4 µmol/L) compared to low levels of bilirubin (5th percentile equal to 5.5 µmol/L) were associated with approx. 0.55 mmol/L (99% CI 0.53–0.56) lower TG levels, with similar inverse associations among women. Multiple-trait analyses using PCA confirmed single-trait analyses. Men and women with mildly elevated bilirubin levels ≥ 17.1 µmol/L, compared to low-normal bilirubin < 10 µmol/L had 13% (99% CI 8%–18%) and 11% (99% CI 4%–17%) lower odds of exceeding systolic BP levels of ≥ 130 mm Hg, respectively.ConclusionsHigher levels of bilirubin were inversely associated with cardiometabolic risk factors including adiposity, dyslipidemia, and hypertension.

Association between 24-h movement guidelines and cardiometabolic health in Chilean adults

This study aimed to examine the association between meeting 24-h movement guidelines and cardiometabolic health in Chilean adults. We used cross-sectional data of 2618 adults from the Chilean National Health Survey 2016–2017. Meeting the 24-h movement guidelines was defined as ≥ 600 MET-min/week of physical activity; ≤ 8 h/day of sitting time; and 7 to 9 h/day of sleep duration. Cardiometabolic health indicators were body mass index, waist circumference, high triglycerides, high blood pressure, type 2 diabetes, metabolic syndrome, and risk of cardiovascular disease in a 10-year period. Meeting none out of three 24-h movement guidelines (vs all three) was associated with higher odds of overweight/obesity (OR 1.67; 95%CI 1.45 to 1.89), high waist circumference (1.65; 1.40 to 1.90), hypertension (2.88; 2.23 to 3.53), type 2 diabetes (1.60; 1.26 to 1.94), metabolic syndrome (1.97; 1.54 to 2.40) and risk of cardiovascular disease (1.50; 1.20, 1.80). Meeting one guideline (vs three) was associated with higher odds of five of out seven cardiometabolic indicators. Our study found that the composition of movement behaviors within a 24-h period may have important implications for cardiometabolic health.

Abstract EP46: Can Middle-Aged Recreational Cyclists Remain In Energy Balance And Weight Stable When Involved In An Extreme Exercise And Energy Expenditure Intervention (4E Study)? Effect On Visceral Adiposity And Features Of Cardiometabolic Risk

Introduction: Weight loss is often considered a key target in lifestyle interventions aimed at reducing cardiometabolic risk in people with overweight/obesity. However, evidence suggests that regular endurance exercise can induce a mobilization of visceral fat in the absence of weight loss. Therefore, the objective of the present study was to test the effect of an extreme exercise prescription not aimed at weight loss on visceral adiposity and on indices of cardiometabolic health. Hypothesis: Despite our attempt to keep the cyclists weight stable during the 1-week exercise intervention, a loss of visceral fat would be observed. Methods: Eleven male recreational cyclists, aged 50 to 66 years and asymptomatic for cardiovascular disease, cycled 1144 km (715 miles) over a period of seven consecutive days. During the intervention, body weight and composition were assessed daily by bioelectrical impedance and cyclists’ caloric intake was increased to keep them in energy balance and weight stable. Their cardiometabolic health profile was documented before and after the intervention and included a fasting blood test, a resting hemodynamic profile, anthropometric, body composition and body fat distribution measurements including visceral adiposity assessed by magnetic resonance. A maximal cardiopulmonary exercise test was performed at baseline. During the intervention, energy expenditure was calculated from the caloric equivalents of oxygen consumption for each heart rate value acquired with a heart rate monitor. Prepared foods were provided to participants and their energy intake was closely monitored. Results: Small decreases in body weight (-0.8 kg, P &lt;0.05), BMI (-0.3 kg/m 2 , P &lt;0.05) and fat mass (-1.5 kg, P =0.0005) as well as a trend towards an increase in lean mass (+0.8 kg, P =0.07) were observed. Visceral adiposity (-14.1 mL, P &lt;0.01) and waist circumference (-3.2 cm, P &lt;0.0001) decreased while subcutaneous adiposity remained unchanged (-2.7 mL, NS). Decreases in total cholesterol (-1.17 mmol/L, P &lt;0.001), LDL cholesterol (-0.97 mmol/L, P &lt;0.0001), non-HDL cholesterol (-1.32 mmol/L, P &lt;0.0001), triglycerides (-0.77 mmol/L, P &lt;0.005), glycated hemoglobin (-0.1%, P &lt;0.005), and resting systolic (-9 mmHg, P &lt;0.01) and diastolic (-7 mmHg, P &lt;0.01) blood pressure were noted. Conclusion: This study showed that recreational master cyclists were not able to remain in energy balance when exposed to a very large exercise prescription performed over one week. However, despite trivial changes in body weight and no change in subcutaneous adiposity, a significant reduction in visceral adiposity was observed. This study shows the differential response of subcutaneous vs visceral adiposity to a very large prescription of endurance exercise, and the inability of body weight changes to fully appreciate the effects of endurance exercise on features of cardiometabolic risk.

Mother-child cardiometabolic health 4-10years after pregnancy complicated by obesity with and without gestational diabetes.

ObjectiveObesity in pregnancy and gestational diabetes (GDM) increase cardiometabolic disease risk but are difficult to disentangle. This study aimed to test the hypothesis that 4–10 years after a pregnancy complicated by overweight/obesity and GDM (OB‐GDM), women and children would have greater adiposity and poorer cardiometabolic health than those with overweight/obesity (OB) or normal weight (NW) and no GDM during the index pregnancy.MethodsIn this cross‐sectional study, mother‐child dyads were stratified into three groups based on maternal health status during pregnancy (OB‐GDM = 67; OB = 76; NW = 76). Weight, height, waist and hip circumferences, and blood pressure were measured, along with fasting glucose, insulin, HbA1c, lipids, adipokines, and cytokines.ResultsWomen in the OB and OB‐GDM groups had greater current adiposity and poorer cardiometabolic health outcomes than those in the NW group (p < 0.05). After adjusting for current adiposity, women in the OB‐GDM group had higher HbA1c, glucose, HOMA‐IR and triglycerides than NW and OB groups (p < 0.05). Among children, adiposity was greater in the OB‐GDM versus NW group (p < 0.05), but other indices of cardiometabolic health did not differ.ConclusionsPoor cardiometabolic health in women with prior GDM is independent of current adiposity. Although greater adiposity among children exposed to GDM is evident at 4–10 years, differences in cardiometabolic health may not emerge until later.
