Purpose The purpose of this study was to evaluate the moderate vigorous physical activity(MVPA) and sedentary time measured by accelerometer. Furthermore, level activity adherence rate guideline(PAG) were compared with self-reported questionnaire. Methods MVPA, time, PAG according age sex examined people who agreed wear accelerometers among participants 2014-2015 Korea National Health Nutrition Examination Survey. To compare relationship between accelerometer questionnaire, Chi-squared test...
The study aimed to examine whether simultaneously meeting the combined guidelines of accelerometer-assessed moderate vigorous physical activity (MVPA) and self-reported muscle-strengthening (MSA) was associated with lower odds metabolic syndrome (MetS) than neither or 1 among Koreans.This cross-sectional analysis included 1,355 participants from Korea National Health Nutrition Examination Survey (2014-2015). Logistic regression used analyze associations across groups MVPA-MSA guideline...
Purpose The main purpose of this study was to compare the relationships between physical activity (measured using an accelerometer vs. self-reported) and cardiovascular disease risk factors. Differences in accelerometry 10-minute bouts total were also compared. Methods Data originated from Korea National Health Nutrition Examination Survey. Logistic regression used predict levels. Results Self-reported could not significantly odds having risk. However, insufficiently active group classified...
Purpose The purpose of this study was to investigate the relationship between physical activity and depression according presence disease. Methods A survey basic assessment were conducted for 2,754 (Male=1,025 Female=1,729) aged 40 over who participated in rural-based cohort study. included activity, scale disease preservation. measured height, weight, body fat percentage. data analyzed by using logistic regression examine prevalence. Results First, reduced prevalence 33% 51%, respectively,...
Purpose:The purpose of this study was to examine the associations aerobic physical activity and musclestrengthening exercise with mental health, respectively.Furthermore, relationship between combined depression, stress, suicidal thoughts also examined.Methods: The association adherence guidelines health analyzed among 27,268 adults who participated in 2014-2018 Korea National Health Nutrition Examination Survey.Logistic regression used predict health. Results:The odds ratio for depression...
Purpose:The purpose was to estimate the socioeconomic status and physical activity level of Korean adults.Methods: A total 27,358 subjects aged over 19 years were included from 2014-2018 Korea National Health Nutrition Examination Survey.The status, main independent inheritance in this study, used as household income (first quartile=highest income) education (elementary, middle school, high college graduates) variables quartile categorical variable values.We perform a regression analysis for...
Background: Quarantine, social distancing, and restricted movement interaction due to the coronavirus disease (COVID-19) have been reported reduce physical activity across several countries. However, few studies evaluated changes in patterns before after COVID-19 among people with disabilities. Therefore, this study aimed evaluate how participation has changed during disabilities South Korea. Methods: This was conducted 3871 persons disabilities, aged 10–69 years, who participated 2020...
ABSTRACT Introduction Several previous studies have reported that hypoxia accidents of fighter pilots are rarer than gravity-induced loss consciousness and spatial disorientation; however, the risk is greater. Therefore, this study aimed to investigate relationship between physical fitness body composition on time useful (TUC) in hypobaric hypoxia. Materials Methods Body testing human participants were performed; subsequently, they exposed at a simulated altitude 25,000 ft. Cognitive was...
Purpose: The purpose of this study was to examine the relationship between sedentary behavior measured by accelerometer and cardiovascular disease risk factors from Korea National Health Nutrition Examination Survey 2014-2015.Methods: participants included in volunteered wear (n=1,407).Ordinal logistic regression used time or breaks factors.Odds ratios 95% confidence intervals were calculated for relationship.Covariates sex, age, educational status, alcohol, smoking, socioeconomic body mass...
Purpose:The main purpose of this study was to examine the relationship between sedentary time and metabolic syndrome.Association accelerometer self-reported on syndrome were also compared.Methods: A total 1,354 adults (men, 492; women, 862), aged 19 65 years, who wore from Korea National Health Nutrition Examination Survey included in analysis.Four subgroups created based quartiles daily for analytical purposes.Metabolic defined according International Diabetes Federation.Logistic regression...
PURPOSE: The purpose of this study was to examine the association between objectively measured physical activity and metabolic syndrome in Korean adults older adults.METHODS: A total 2,191 from Korea National Health Nutrition Examination Survey 2014 2017 were analyzed. Participants categorized into three groups (‘Inactive’, ‘Active’, ‘Highly active’) according guidelines. chi-square test performed confirm whether guidelines met difference age group. Logistic regression used predict...
본 연구의 목적은 한국 성인의 유산소 및 근력 강화 활동에 따른 동맥경화지수(atherogenic index of plasma, AIP)의 연관성을 조사하며, 그 관계에 있어 양-반응 관계를 분석하는 것이다. 국민건강영양조사 2014-2019년도 자료를 활용하여 복합표본 설계 방법에 따라 31,119명의 활동 지침 달성 여부를 분석하였으며, AIP와의 확인하기 위해 교차분석, 로지스틱 회귀분석을 실시하였다. 결과는 다음과 같다. 1) AIP의 수치에 지침을 모두 충족하지 않거나, 활동만 충족, 그리고 두 모두를 충족하는 비율은 통계적으로 유의한 차이가 나타났다(p.05). 2) 중-고강도 활동이 없는 인원을 참조그룹으로 하였을 때 달성과 관계없이 시간이 증가할수록 승산비가 감소되었다(OR: 0.78, 95% CI: 0.68-0.89). 또한, 달성하지 못한 신체활동 참여 일수가 감소되었다(OR:0.69, 0.61-0.77). 3) 못하는 집단을 달성한 그룹에서 가장 크게...
The aim of this study was to identify the stepping cadence patterns in Korean adults by using objectively measured accelerometer data analyze time spent each category sex and age.During 2014-2015 National Health Nutrition Examination Survey, 1,703 males females aged 19-64 years provided at least 1 valid day (wearing an ≥ 10 hr/d). mean cumulative percentage per 8 categories (0, 1-19, 20-29, 30-59, 60-79, 80-99, 100-119, 120 steps/min) age group were calculated.Cumulative decreased across...
PURPOSE This study aimed to verify the criterion validity of two-minute step test in older Korean adults, develop an equation for predicting VO<sub>2max</sub>, and cross-validation.METHODS A submaximal exercise walk were performed on 150 adults (74 males 74 females) aged 65 years or older. Correlation analysis was confirm validity. An estimating VO<sub>2max</sub> developed through multiple regression analysis, cross-validation confirmed by performing a correlation...
PURPOSE: The purpose of this study was to investigate the effect body composition and physical fitness Air Force pilots on hypoxic tolerance (Time Useful Consciousness, TUC) under conditions. METHODS: At sea level, we measured 99 adults who were not exposed environment. In hypoxia chamber, which can simulate high altitudes, set altitude 25,000 feet TUC maximum heart rate (HRmax(H)). Pearson's Correlation used determine relationship between other variables, multiple regression performed...
Background/Objectives: Although many studies have reported that physical activity (PA) and exercise significant positive effects on various health aspects, very few classified persons by their disability types investigated PA participation patterns, along with obstacle factors.This study aimed to analyze compare patterns factors classifying a large sample of Koreans types.Methods/Statistical analysis: Data regular barriers were collected in 2014 2017 from 11,815 disabilities (ages 0-99...
