A mixed method study to determine the prevalence of childhood obesity and determinants of physical activity and gadgets use amongst school-going children (standard 1st to 10th) from an urban area located in central India

Introduction The word obesity comes from the Latin “obesus,” which means “pump” or “having eaten oneself fat.” Childhood obesity is a major problem in India. Physical activity is critical for obesity prevention. Childhood Obesity is a proven risk factor for many noncommunicable diseases in adults. Environmental factors, habits, and cultural contexts have influenced the worldwide obesity epidemic. Obesity during childhood can have a comprehensive impact on a child’s overall health, affecting not only their physical well-being, but also their social and emotional development. It can influence confidence levels, social interactions, and even academic performance, leading to reduced quality of life. Aim This study aimed to determine the prevalence of obesity and examine the pattern of physical activity and gadget use among school-going children (1st -10th). Method This was a descriptive cross-sectional study with a mixed-method component that will be conducted in the urban field practice of a tertiary care hospital in central India among school-going children (std1st-std 10th). Quantitative data were collected by house-to-house surveys in systematically selected random households, while in-depth interviews were conducted among parents from randomly selected households. This study aimed to ascertain the frequency of obesity and physical activity patterns and examine parents’ opinions regarding technology use, exercise, and nutrition in their offspring. It will provide insights into the burden of childhood obesity along with appropriate strategies to plan based on the determinants and perceptions identified.

Unveiling Fall Triggers in Older Adults: A Machine Learning Graphical Model Analysis.

While existing research has identified diverse fall risk factors in adults aged 60 and older across various areas, comprehensively examining the interrelationships between all factors can enhance our knowledge of complex mechanisms and ultimately prevent falls. This study employs a novel approach-a mixed undirected graphical model (MUGM)-to unravel the interplay between sociodemographics, mental well-being, body composition, self-assessed and performance-based fall risk assessments, and physical activity patterns. Using a parameterized joint probability density, MUGMs specify the higher-order dependence structure and reveals the underlying graphical structure of heterogeneous variables. The MUGM consisting of mixed types of variables (continuous and categorical) has versatile applications that provide innovative and practical insights, as it is equipped to transcend the limitations of traditional correlation analysis and uncover sophisticated interactions within a high-dimensional data set. Our study included 120 elders from central Florida whose 37 fall risk factors were analyzed using an MUGM. Among the identified features, 34 exhibited pairwise relationships, while COVID-19-related factors and housing composition remained conditionally independent from all others. The results from our study serve as a foundational exploration, and future research investigating the longitudinal aspects of these features plays a pivotal role in enhancing our knowledge of the dynamics contributing to fall prevention in this population.

COVID-19 Stay-at-home mandates impacts daily ambulatory bout intensity and duration in elementary school-aged children: A wearable sensor based analysis

IntroductionSARS COVID-19 pandemic resulted in major changes to how daily life was conducted. Health officials instituted policies to decelerate the spread of the virus, resulting in changes in physical activity patterns of school-aged children. The aim of this study was to utilize a wearable activity monitor to assess ambulatory activity in elementary-school aged children in their home environment during a COVID-19 Stay-at-Home mandate. MethodsThis institutional review board approved research study was performed between April 3rd – May 1st of 2020 during which health officials issued several stay-at-home (shelter-in-place) orders. Participant recruitment was conducted using a convenience sample of 38 typically developing children. Participants wore a StepWatch Activity Monitor for one week and data were downloaded and analyzed to assess global ambulatory activity measures along with ambulatory bout intensity/duration. For comparison purposes, SAM data collected before the pandemic, of a group of 27 age-matched children from the same region of the United States, was included. Statistical analyses were performed comparing SAM variables between children abiding by a stay-at-home mandate (Stay-at-Home) versus the Historical cohort (alpha=0.05). ResultsStay-at-Home cohort took on average 3737 fewer daily total steps compared to the Historical cohort (p<0.001). Daily Total Ambulatory Time (TAT), across all days was significantly lower in the Stay-at-Home cohort compared to the Historical cohort (mean difference: 81.9 minutes, p=0.001). The Stay-at-Home cohort spent a significantly higher percentage of TAT in Easy intensity ambulatory activity (mean difference: 2%, p<0.001) and therefore a significantly lower percentage of TAT in Moderate+ intensity (mean difference: 2%, p<0.001). ConclusionsThe stay-at-home mandates resulted in lower PA levels in elementary school-aged children, beyond global measures to also bout intensity/duration. It appears that in-person school is a major contributor to achieving higher levels of PA and our study provides additional data for policymakers to consider for future decisions.

Patterns of Physical Activity of Adolescents With ADHD in the School Context: A Cross-Sectional Study for Clinical Practice

Objectives: To describe the daily Physical Activity (PA) patterns of adolescents with Attention-deficit/hyperactivity disorder (ADHD), to analyze the differences in terms of PA patterns between adolescents with ADHD and those without ADHD, and to study the factors associated with achieving the daily PA recommendations. Methods: The sample was composed of 778 adolescents who provided complete information on their PA patterns through the Physical Activity Questionnaire for Adolescents (PAQ-A). Of these, 97 had ADHD according to DSM-5 criteria. Results: The results show that being a girl or being of foreign origin and having ADHD have an impact on the achievement of the recommended amount of daily PA. Conclusions: When promoting PA in adolescents with ADHD within the school environment, it is necessary to consider different domains and specific contexts of a school day, paying special attention to girls and adolescents with ADHD of immigrant origin.

Design and methods of the mobile assessment of cognition, environment, and sleep (MACES) feasibility study in newly diagnosed breast cancer patients

Endocrine therapy (ET) for breast cancer treatment is associated with cognitive complaints, but their etiology is poorly understood. To address this, we developed and implemented an ambulatory assessment protocol consisting of wearable activity monitors, brief surveys of affect, context, and perceived impairments, and ultra-brief performance-based measures of cognition. Newly diagnosed, ER/PR+, stage 0-III, female breast cancer patients, were recruited. Ambulatory assessments were conducted on smart phones and wearable activity monitors were used to monitor sleep and physical activity. Participants were asked to complete five 7-day measurement bursts (one before starting ET and one each month for 4 consecutive months while on ET). We observed a consent rate of 36%, 27 women completed the study. Of the women that withdrew, 91% dropped prior to the midpoint of follow up. There were no significant differences in demographics, clinical breast cancer characteristics, sleep or physical activity patterns, or measures of cognition between women who completed versus withdrew. Women who did not complete the study provided fewer valid days of baseline data. In conclusion, while some women may be overwhelmed with their cancer diagnosis, we did not identify any predictive characteristics of women whom did not complete the study. This novel method enables the prospective study of psychological changes associated with cancer treatment, capturing a wide array of information about behavior, experience, and cognition, thus providing a picture of the lived experiences of cancer patients before and during exposure to ET.

Enhancing inclusive physical activity for students with disabilities: Patterns and opportunities

Physical activities and sports (PAS) participation primarily aim to contribute to enhancing the basic motor skills of students and their physical competencies to directly promote the behavioral, cognitive, and social skills of students to help enhance their future physical activity patterns. Regular physical activity participation among children with disabilities greatly fosters independence, coping abilities, competitiveness, and teamwork. Although active physical activities are beneficial, children with disabilities’ participation in physical activities has been reported to be little as a result of students’ disabilities and their lack of opportunities for participation. However, literature is yet to report on the types of PAS regularly participated in by students with disabilities, how frequently they engage in such activities, and how long a time they spend during their participation. This current study employed an explanatory sequential mixed method design that helped in the collection of both quantitative data (questionnaire) and qualitative data (interviews) from 194 (comprising 68.0% male and 32.0% female) students with disabilities and three teachers on types of PAS students with disabilities mostly participate in, how frequent and how long a time they spend during PAS participation. The findings of this study revealed students very often participate in physical activities in different activities for a long period as long as activities are made available, and opportunities provided. It is, therefore, recommended that not only should disability-friendly physical activities and sporting events be organized frequently and encouraged among students in special schools, but stakeholders should make opportunities available to students to participate.

Time-dependent complexity characterisation of activity patterns in patients with Chronic Fatigue Syndrome

BackgroundChronic Fatigue Syndrome patients suffer from symptoms that cannot be explained by a single underlying biological cause. It is sometimes claimed that these symptoms are a manifestation of a disrupted autonomic nervous system. Prior works studying this claim from the complex adaptive systems perspective, have observed a lower average complexity of physical activity patterns in chronic fatigue syndrome patients compared to healthy controls. To further study the robustness of such methods, we investigate the within-patient changes in complexity of activity over time. Furthermore, we explore how these changes might be related to changes in patient functioning.MethodsWe propose an extension of the allometric aggregation method, which characterises the complexity of a physiological signal by quantifying the evolution of its fractal dimension. We use it to investigate the temporal variations in within-patient complexity. To this end, physical activity patterns of 7 patients diagnosed with chronic fatigue syndrome were recorded over a period of 3 weeks. These recordings are accompanied by physicians’ judgements in terms of the patients’ weekly functioning.ResultsWe report significant within-patient variations in complexity over time. The obtained metrics are shown to depend on the range of timescales for which these are evaluated. We were unable to establish a consistent link between complexity and functioning on a week-by-week basis for the majority of the patients.ConclusionsThe considerable within-patient variations of the fractal dimension across scales and time force us to question the utility of previous studies that characterise long-term activity signals using a single static complexity metric. The complexity of a Chronic Fatigue Syndrome patient’s physical activity signal does not suffice to characterise their high-level functioning over time and has limited potential as an objective monitoring metric by itself.

Physical activity levels and sleep disturbances in Indonesian primary school students during the COVID-19 pandemic

Background During the coronavirus disease-2019 (COVID-19) pandemic, the Indonesian government implemented a large-scale, social restriction policy, including the closure of schools and recreational facilities, which potentially altered children’s physical activity and sleep patterns. Objective To analyze for a possible association between physical activity levels and sleep disturbances in Indonesian primary school students during the COVID-19 pandemic. Methods This cross-sectional study was conducted on 437 children aged 7-13 years using data collected online in April-August 2020, including children’s sociodemographic characteristics, physical activity levels, and sleep patterns. The translated Indonesian version of Physical Activity Questionnaire for Children (PAQ-C) and the Children Sleep Habits Questionnaire-Abbreviated (CSHQ-A) were used to collect data. The data analyzed consisted of sociodemographic factors and physical activity levels, sociodemographic factors and sleep disturbances, and physical activity levels and sleep disturbances. Results Most children were physically inactive (60.87%) and experienced sleep disturbances (73.23%) during the COVID-19 pandemic. Female sex and physical inactivity were significantly associated. Male sex and sleep disturbances were significantly associated. Age 7 as the lowest age group was significantly associated with sleep disturbances. There was no significant association (P=0.248) between physical activity levels and sleep disturbances. Conclusion Most Indonesian primary school students were physically inactive and had sleep disorders during the COVID-19 pandemic. Female sex and physical inactivity were significantly associated, while male sex and sleep disturbances were significantly associated, age 7 (lower age group) and sleep disturbances were significantly associated. There was no significant association between physical activity levels and sleep disturbances in Indonesian primary school students during the COVID-19 pandemic.

IJCM_119A: A comparative cross-sectional study of dietary and physical activity pattern in a rural area of Karnataka

Background: In a country of 1.3 billion people with cultural and lifestyle diversities, several previous attempts have been made to compile the burden of cardiovascular diseases. 3.2 million people die each year due to physical inactivity. Traditionally, studies of diet and CVD risk have focused on individual foods and macronutrients. Yet, food is typically consumed in combination and not in isolation. Objective: To compare the dietary pattern and physical activity among 2 different age groups of people in a village of coastal Karnataka. Methodology: A cross-sectional study conducted in a rural area of coastal Karnataka with sample size of 320 (160 each from 20–30 years &amp; 50–60 years group). The dietary pattern involving daily intake of carbohydrates, fats, proteins and total calories was assessed using the 7-day dietary cycle. Physical activity pattern was assessed using IPAQ study tool. Statistical analysis was done using SPSS; parametric and non-parametric tests were done. p&lt;0.05 was taken as statistically significant. Results: 20 - 30 years age group had a consumption pattern of daily carbohydrates, proteins and fat intake of 24.11 g%, 10.89 g% &amp; 20.41 g% as compared to 32.96 g%, 13 g% and 29.44 g% respectively in the 50 - 60 years age group. Total calorie intake, daily carbohydrate, protein and fat intake was significantly more in the 20-30 years age group as compared to 50-60 years age group. Gram-percentage consumption of carbohydrates, proteins and fats as part of total calories was significantly lesser as compared to 50-60 years age group. 50.6% of the 20-30 years &amp; 13.8% of the 50-60 years age group were physically inactive. Conclusion: The study population followed an unbalanced diet with addition of trans fat and added sugars. Majority were physically inactive and the daily work load has decreased considerably with people spending most of their leisure time by sitting.

Investigating nutritional status and body composition in children with cerebral palsy; the Eat, Sleep Play-CP study

Cerebral palsy (CP), or to use the Te Reo term “Hōkai Nukurangi”, is an umbrella name for a group of permanent neurodevelopmental disorders, affecting movement and posture(1), and is the most common childhood onset physical disability globally. The available literature on the nutritional status of children with CP describes high rates of malnutrition, however data appears to be skewed towards children of higher levels of impairment impacting functional independence. Less is known about the nutritional status of children with lower levels of impairment. The aim of the “Eat, Sleep, Play-CP” study was to evaluate total energy intake, total protein intake and the timing of protein intake in relation to physical activity for children with CP across all functional levels living in Aotearoa New Zealand. Children with CP aged 5-12 years were invited to participate in an observational assessment of dietary intake using parent reported 24-hour dietary recall (Intake 24) on three non-consecutive days, accompanied by a questionnaire capturing self-reported sleep and physical activity patterns. Body composition was assessed via whole body dual energy X-ray absorptiometry scan. Nine participants (6 males, median age: 10 years, n = 2 Māori), across Gross Motor Function Classification System levels I-IV, and Eating and Drinking Classification System levels I-III took part in the study. The median total energy intake was 7267kJ/d (range 5355-10731.96kJ/d), and median protein intake was 67g/d (range 49-111g/d). According to the Nutrient Reference Values for Australia and New Zealand (NRV)(2), 3 of the 9 participants (33%) were within the recommended range for energy intake according to their age and reported physical activity levels. Of the other 6, 4 were below and 2 were above the recommended ranges. All 9 met the recommended protein intake (NRV). Participants had a median percentage body fat of 40% (range 20-46%), and non-fat mass of 58% (range 52-76%). Five participants fell within the overweight or obese range for their age and sex, three of whom were within the recommended range of total energy daily intake according to NRVs. This outcome may indicate that for some children with CP, recommendations could be over-estimating the actual requirements. These early results may bring in to question current practice around guidance for energy intake requirements for children with CP and their whānau to support healthy body composition. Further investigations are needed to establish whether specific energy intake guidelines are required for children with CP.

Association Between Physical Activity and the Prevalence of Kidney Stones in American Adults: Results From a Multiyear National Survey

ObjectiveTo investigate the association between physical activity and the prevalence of kidney stones. MethodsA cross-section study was conducted using data from National Health and Nutrition Examination Survey 2007-2018. Physical activity was evaluated based on the Global Physical Activity Questionnaire. Multivariable logistic regression was performed to elucidate the association between physical activity (patterns, intensity, duration and frequency of moderate and vigorous physical activity) and the prevalence of kidney stones after adjusting for potential confounders. Stratified and interaction analyses were conducted to detect potential effect modifiers. In addition, physical activity was assessed using metabolic equivalent and physical volume, and followed the regression above. Water intake was obtained from the day 2 dietary recall and was included in the sensitivity analysis. ResultsA total of 34,390 participants were included in the analysis. The multivariable logistic regression revealed that individuals who engaged in moderate physical activity for 30-60 minutes per day had a significant inverse association with the prevalence of kidney stones in the fully-adjusted model (OR=0.804, 95%CI 0.700 to 0.923), while no more significant finding was observed for other physical activity parameters. Interaction and stratified analyses indicated no covariate modifying the association. The results above were robust in the sensitivity analysis. ConclusionThe duration of moderate physical activity (30-60 mins/day) is inversely associated with the prevalence of kidney stones, while no more significant association was observed between other physical activity parameters (including patterns, intensity, duration and frequency of vigorous physical activity, frequency of moderate physical activity) and kidney stones. Data availabilityData available in a publicly accessible repository that does not issue DOIs. Publicly available datasets were analyzed in this study.

A pilot Randomized Controlled Trial (RCT) study protocol for assessing physical activity in individuals diagnosed with Borderline Personality Disorder (PABORD)

IntroductionMost treatments for severe mental disorders involve either pharmacotherapy or psychological interventions, which show mild to moderate effectiveness and may not lead to complete remission. Physical activity (PA), effective in enhancing physical health among the general population, emerges as a potential adjunctive treatment option that can address the existing gaps.Borderline Personality Disorder (BPD) is a severe condition associated with profound psychosocial impairment, a heightened risk of suicide, and considerable burden on informal caregivers and mental health service providers. While there is a lack of approved medications for individuals with BPD, psychosocial interventions demonstrated good efficacy. However, the implementation of these treatments is limited by the demanded extensive training for staff. No studies have investigated the effectiveness of structured PA as an adjunctive treatment for individuals with BPD.ObjectivesThe primary objective of this study is to assess whether the intervention group outperforms the control group in terms of improvement on a standardized assessment scale evaluating BPD psychopathology, the Zanarini Rating Scale for Borderline Disorder. Secondary objective is to assess whether the intervention group can increase and sustain higher levels of PA. We hypothesise that a structured PA program will demonstrate superior results compared to the psychoeducation control group concerning PA levels upon completion of the intervention. Additionally, we hypothesise that the intervention group will exhibit enhanced outcomes in psychopathology, functioning, and sleep.MethodsThe PABORD Randomized Controlled Trial is designed for female outpatient individuals diagnosed with BPD aged 18-40 years. This trial will involve two distinct groups: (i) an intervention group (25 participants) that will engage in a 12-week structured PA program under the supervision of a sports medicine physician; (ii) a control group (25 individuals) that will undergo a 12-week psychoeducation program focused on PA and diet.Patients are assessed at three different time points. Standardized assessments include psychopathology, psychosocial functioning, sleep, menstrual cycle and nutrition data. Measurements are taken on the amount and intensity of PA and sleep patterns using a biosensor device (Actigraph GT9X), dynamometric measures and BMI. Biomarkers and hormonal cycles are examined through the collection of plasma and saliva samples.The trial is financially supported through donations (5x1000 fund), and has been submitted to the local Ethics Committee for approval. The trial registration process is also currently in progress.ResultsNot yet available.ConclusionsThe study will provide new knowledge which may enhance our treatment options with patients suffering from BPD.Disclosure of InterestNone Declared

IJCM_391A: Impact of Adolescent Physical Activity and Sedentary Behaviour on Quality of Life: A Cross-Sectional Study conducted in the Urban Slums of Berhampur, Ganjam

Background: Adolescence is a pivotal phase marked by significant physical, emotional, and cognitive changes. The lifestyle choices made during this period can profoundly affect the quality of life (QOL) of adolescents. However, research on this topic is limited, especially within the unique context of urban slums. Objective: This cross-sectional study aims to investigate the impact of physical activity and sedentary behaviour on QOL among adolescents residing in the urban slums of Berhampur, Ganjam. Methodology: A multistage cluster sampling method was employed to select adolescents aged 12-18 living in urban slum areas. WHO-QOL were utilized to collect data on physical activity, sedentary behaviour, and QOL using validated instruments. Data analysis encompassed descriptive statistics, inferential analyses, and regression models to explore the relationships between physical activity, sedentary behaviour, and QOL. Socio-demographic variables were also considered. Results: Preliminary findings reveal diverse physical activity patterns among adolescents, with a notable proportion engaging in insufficient levels of physical activity. Sedentary behaviours, particularly prolonged screen time, were prevalent. QOL assessments identified variations in physical, emotional, and social well-being domains. Regression analyses indicated a positive association between higher levels of physical activity and improved QOL, while sedentary behaviour, especially extensive screen time, was associated with decreased QOL. Socio-demographic factors, including gender and socio- economic status, were identified as influential factors in these associations. Conclusion: This study underscores the significant interplay between physical activity, sedentary behaviour, and QOL among adolescents residing in urban slums. It emphasizes the need for targeted interventions aimed at promoting healthier lifestyles within this underserved population. The findings provide essential insights for policymakers, healthcare providers, and educators to develop evidence-based strategies that can enhance the well-being of adolescents in similar contexts worldwide. Addressing the unique health challenges faced by adolescents in urban slums is crucial for improving their overall QOL and health outcomes.

310 Digital Physical Activity Phenotype before Cerebrovascular Disease: A Retrospective Study of Accelerometer-Measured Behavior in UK Biobank Observational Cohort

OBJECTIVES/GOALS: To investigate digital behavior patterns before cerebrovascular disease (CeVD), we compared accelerometer-measured physical activity (PA) phenotypes of future CeVD patients versus controls in UK Biobank. METHODS/STUDY POPULATION: Accelerometer data from 76,525 eligible participants monitored for 7-days (Jan. 2013-Dec. 2015) was classified into four categories: sedentary, light PA (LPA), moderate-to-vigorous PA (MVPA), and sleep. Covariables and diagnoses were defined using baseline data and patient records. Daily PA patterns associated with incident CeVD were compared to controls using negative binomial regression models. RESULTS/ANTICIPATED RESULTS: Adult participants with future CeVD (n = 2,163) spent 4.4% less time in MVPA (Incident Rate-Ratio (IRR) 0.956; 95% CI = 0.923-0.992; p = 0.016) compared to controls. During 0:00-5:59h (midnight to 5:59AM), future CeVD patients were less likely to sleep (IRR = 0.985; 95% CI = 0.977-0.992; p &lt;0.001) but more likely to be sedentary (IRR = 1.189; 95% CI = 1.098-1.290; p &lt;0.001) or in LPA (IRR = 1.108; 95% CI = 1.015-1.211; p &lt;0.001). In subgroup analyses, decreased MVPA was observed in current/former smokers (IRR = 0.887; 95% CI = 0.819-0.963), males (IRR = 0.931; 95% CI = 0.870-0.997), and the unemployed/retired (IRR = 0.923; 95% CI = 0.856-0.998), an effect more pronounced in depressed patients (p for interaction = 0.044) and prolonged (&gt; 2 hr/day) screen users (p for interaction = 0.018). DISCUSSION/SIGNIFICANCE: The digital phenotype of PA prior to CeVD is characterized by less sleep during 0:00-5:59h and less daily MVPA, demonstrating the utility of accelerometer data in identifying candidates for preventative intervention.

Physical Activity, Mental Activity, and Risk of Incident Stroke: A Prospective Cohort Study.

Cumulative evidence suggests a correlation between physical or mental activity and the risk of stroke. However, the combined impact of these activities on stroke onset remains unexplored. This study identified physical and mental activity patterns using principal component analysis and investigated their associations with risk of incident stroke in the general population. Our study was sourced from the UK Biobank cohort between 2006 and 2010. Information on physical and mental-related activities were obtained through a touch-screen questionnaire. The incident stroke was diagnosed by physicians and subsequently verified through linkage to Hospital Episode Statistics. Principal component analysis was used to identify potential physical and mental activity patterns. Cox proportional hazard regression models were performed to calculate hazard ratios (HRs) and 95% CIs of incident stroke, adjusting for potential confounders. The initial UK Biobank cohort originally consisted of 502 411 individuals, of whom a total of 386 902 participants (aged 38-79 years) without any history of stroke at baseline were included in our study. During a median follow-up of 7.7 years, 6983 (1.8%) cases of stroke were documented. The mean age of the included participants was 55.9 years, and the proportion of women was 55.1%. We found that multiple individual items related to physical and mental activity showed significant associations with risk of stroke. We identified 4 patterns of physical activity and 3 patterns of mental activity using principal component analysis. The adherence to activity patterns of vigorous exercise, housework, and walking predominant patterns were associated with a lower risk of stroke by 17% (HR, 0.83 [95% CI, 0.78-0.89]; 20% (HR, 0.80 [95% CI, 0.75-0.85]; and 20% (HR, 0.80 [95% CI, 0.75-0.86), respectively. Additionally, the transportation predominant pattern (HR, 1.36 [95% CI, 1.28-1.45) and watching TV pattern (HR, 1.43 [95% CI, 1.33-1.53) were found to be significantly associated with a higher risk of stroke. These associations remained consistent across all subtypes of stroke. Activity patterns mainly related to frequent vigorous exercise, housework, and walking were associated with lower risks of stroke and all its subtypes. Our findings provide new insights for promoting suitable patterns of physical and mental activity for primary prevention of stroke.

The association between different physical activity (PA) patterns and cardiometabolic index (CMI) in US adult population from NHANES (2007–2016)

BackgroundPhysical activity (PA) is widely recommended for preventing and combating obesity, but the most effective PA pattern for treating obesity remains unclear. Cardiometabolic index (CMI), derived from waist height ratio and triglycerides to high-density lipoprotein-cholesterol ratio, is a novel indicator for evaluating obesity. However, the relationship between different PA patterns and CMI remains unelucidated. ObjectiveThis study aimed to explore the association between different PA patterns and CMI in U.S. adults. MethodsParticipants with complete information in CMI, PA patterns, and other covariates in the National Health and Nutrition Examination Survey database (2007–2016) were included in this study. Multivariate linear regression models were utilized to explore the relationship between PA patterns and CMI. Moreover, stratified analyses, interaction tests and restricted cubic spline (RCS) regression analysis were used to investigate the stability and nonlinearity of the association, respectively. ResultsA total of 16,442 adults were included in this study. After adjusting for all potential covariates, only the regularly active group was significantly associated with CMI reduction (β = −0.13, 95% CI: 0.19 to −0.07, P < 0.0001), while the weekend warriors group did not achieve equivalent CMI reduction (β = −0.09, 95% CI: 0.32 to 0.14, P = 0.4204). Subgroup analyses and interaction tests revealed that the CMI-PA association was more pronounced in the subgroup with age≤45 or >60, with higher education level, and who are current drinkers. Furthermore, RCS analysis indicated that total PA in a week was significantly, nonlinearly associated with CMI in non-inactive adults, and that a total of PA more than 330 min can reap favorable CMI reduction. ConclusionBeing regularly active is associated with significant CMI reduction, while being weekend warriors and insufficiently active do not achieve equivalent benefits. For non-inactive individuals, engaging in PA for more than 330 min weekly helps to reduce CMI effectively.

Association of Physical Activity Patterns with the Metabolic Syndrome in Korean Adults: A Nationwide Cross-Sectional Study.

Recent research has focused on a new group called the "weekend warriors". These individuals accumulate their recommended moderate to vigorous physical activity (MVPA) over just 1-2 days, often during weekends, while remaining relatively inactive during the rest of the week. However, the effects of engaging in low-frequency MVPA on the risk of metabolic syndrome (MetS) are not well understood. This study investigated the association between physical activity patterns and the risk of MetS among Korean adults. This study included 26,197 participants (11,804 male and 14,393 female) aged 20 years from the Korea National Health and Nutrition Examination Survey. MVPA was measured using a global physical activity questionnaire. MetS was defined as the presence of more than three risk factors. The odds ratio (OR) for MetS was 0.60 (95% confidence interval [CI] = 0.52, 0.70) in the "regularly active" group and 0.82 (95% CI = 0.69, 0.98) in the "weekend warrior" group compared to that in the inactive group (reference), which controlled for all covariates. For sensitivity analyses, the results across all subgroups exhibited similar patterns, with more pronounced effects observed in women, middle-aged individuals, and non-drinkers/light drinkers. Our findings suggest that concentrated bouts of moderate to vigorous physical activity, even if undertaken infrequently, confer health benefits that align with the recommended guidelines. This study contributes to the growing evidence on the relationship between physical activity patterns and MetS risk in Korean adults. The study also emphasizes the potential of different activity patterns in mitigating metabolic risk.
