OBJECTIVES
To identify the distinct trajectories of sedentary behavior (SB) and explore whether reduced cardiovascular disease (CVD) risk was associated with a distinct trajectory of physical activity (PA).
METHODS
We analyzed data from 6,425 people who participated in the Korean Health Panel Survey over a period of 10 years. The participants’ self-reported SB and PA were assessed annually, and trajectory groups were identified using a group-based trajectory model for longitudinal data analysis. Logistic regression analysis was performed to assess the association between CVD risk (10-year cumulative incidence) and the trajectories of SB and PA. The adjusted variables included socio-demographic factors, the predisposing diseases of CVD, and baseline health behaviors.
RESULTS
Trajectory analysis identified 4 SB trajectory groups: SB group 1 (low and slightly increasing trend, 53.1%), SB group 2 (high and rapidly decreasing trend, 14.7%), SB group 3 (high and slightly decreasing trend, 9.9%), and SB group 4 (low and rapidly increasing trend, 22.2%). The 3 PA trajectory groups were PA group 1 (moderate and slightly decreasing trend, 32.1%), PA group 2 (low and slightly decreasing trend, 57.3%), and PA group 3 (maintained inactivity, 10.7%). By the 10-year follow-up, 577 cases of incident CVD had occurred. We also noted a 50% reduction in the risk of CVD when SB group 4 was accompanied by PA group 1 (odds ratio, 0.50; 95% confidence interval, 0.28 to 0.90).
CONCLUSIONS
Despite increased time spent in SB, maintaining PA about 2 days to 3 days per week reduced the occurrence of CVD.; Summary

OBJECTIVES
During the coronavirus disease 2019 (COVID-19) pandemic, a growing prevalence of racial and ethnic discrimination occurred when many Americans struggled to maintain healthy lifestyles. This study investigated the associations of racial and ethnic discrimination with changes in exercise and screen time during the pandemic in the United States.
METHODS
We included 2,613 adults who self-identified as non-Hispanic White, non-Hispanic Black, non-Hispanic Asian, or Hispanic from the Health, Ethnicity, and Pandemic study, a cross-sectional survey conducted among a nationally representative sample of United States adults between October and November 2020. We assessed self-reported racial and ethnic discrimination by measuring COVID-19-related racial and ethnic bias and examined its associations with changes in exercise and screen time using multivariable logistic regression models. We analyzed data between September 2021 and March 2022.
RESULTS
COVID-19-related racial and ethnic bias was associated with decreased exercise time among non-Hispanic Asian (odds ratio [OR], 1.46; 95% confidence interval [CI], 1.13 to 1.89) and Hispanic people (OR, 1.91; 95% CI, 1.32 to 2.77), and with increased screen time among non-Hispanic Black people (OR, 1.94; 95% CI, 1.33 to 2.85), adjusting for age, sex, education, marital status, annual household income, insurance, and employment status.
CONCLUSIONS
Racial and ethnic discrimination may have adversely influenced exercise and screen time changes among racial and ethnic minorities during the COVID-19 pandemic in the United States. Further studies are needed to investigate the mechanisms through which racial and ethnic discrimination can impact lifestyles and to develop potential strategies to address racial and ethnic discrimination as a barrier to healthy lifestyles.; Summary

Abstract Summary PDF Supplementary Material: Abstract
OBJECTIVES
The reported effects of digital media overuse on physical activity among adolescents are inconsistent. This study examined the association between hours of digital media use and lack of moderate-intensity physical exercise (mPE) according to the type of digital media.
METHODS
This study included 1,837 middle school students from the iCURE (Internet user Cohort for Unbiased Recognition of gaming disorder in Early Adolescence) study conducted in Korea. Hours spent using digital media were measured by self-reported daily usage time for Internet games, messengers, social media, and watching game streaming on weekdays. Lack of mPE was defined as performing a minimum of 30 minutes at a time less than twice weekly. Multivariable logistic regression analysis stratified by sex was performed.
RESULTS
Among male students, the group with the highest hours of using either Internet games or watching game streaming was more likely to lack mPE than each non-user group. In contrast, among male students, the group using either messengers or social media had a higher rate of mPE compared to each non-user group. Female students showed no association between hours spent using Internet games, messengers, social media, or watching game streaming and a lack of mPE.
CONCLUSIONS
Among male middle school students in Korea, the excessive use of Internet games or watching game streaming was associated with a lack of mPE. Thus, guidelines should be established regarding adolescent use of internet games and watching game streaming.; Summary

Abstract

OBJECTIVES
Job strain is positively associated with incident hypertension, while increasing leisure-time physical activity (LTPA) can reduce incident hypertension. However, the joint associations of job strain and LTPA with incident hypertension among United States workers have yet to be investigated. This study examined the independent and joint associations of job strain and LTPA with incident hypertension.

METHODS

This prospective cohort study (n=1,160) utilized data from the population-based Midlife in the United States study. The associations of job strain and LTPA at baseline with incident hypertension during follow-up were examined using Cox proportional hazards models. High job strain was derived from a combination of high job demands and low job control, and high LTPA was defined as engagement in moderate or vigorous LTPA at least once per week.

RESULTS

During 9,218 person-years of follow-up, the hypertension incidence rate was 30.6 (95% confidence interval [CI], 27.3 to 34.3) per 1,000 person-years. High job strain was associated with a higher risk for hypertension than low job strain (adjusted hazard ratio [aHR], 1.29; 95% CI, 1.00 to 1.67). High LTPA was associated with lower hypertension risk than low LTPA (aHR, 0.77; 95% CI, 0.60 to 0.98). Hypertension risk was higher among workers with high job strain and low LTPA than among those with low job strain and high LTPA (aHR, 1.70; 95% CI, 1.18 to 2.43).

CONCLUSIONS

Job strain and LTPA showed positive and inverse associations, respectively, with incident hypertension. The combination of high job strain and low LTPA was associated with the highest risk for hypertension.

Summary

Korean summary

Key Message
High job strain and low leisure-time physical activity are independent risk factors for hypertension among workers, and those with high job strain and low leisure-time physical activity are at the highest risk, so it is critical that policy interventions target job strain and leisure-time physical activity to reduce hypertension.

Abstract

OBJECTIVES
This study aimed to describe trends in health behaviours between 2011 and 2020 and compare the changes in these behaviours between the 2020 COVID-19 pandemic and previous periods according to socio-demographic variables.

METHODS

This study used data from the 2011 to 2020 Korea National Health and Nutrition Examination Survey. Current cigarette smoking, high-risk drinking, and inadequate physical activity levels were used as health behaviour indicators. The age-standardized prevalence, differences in prevalence between the periods, and the annual percentage change (APC) were calculated.

RESULTS

Current cigarette smoking showed a decreasing trend (APC, -2.6), high-risk drinking remained unchanged, and inadequate physical activity levels increased (APC, 3.5) during 2011-2020. There were significant differences in high-risk drinking (3.1%p; 95% confidence interval [CI], 0.3 to 5.9) and inadequate physical activity levels (4.3%p; 95% CI, 0.4 to 8.1) between 2019 and 2020 in men. Among men, increased high-risk drinking was found in those aged 40-49 years, non-single households, urban residents, and the middle and highest income groups between 2019 and 2020. The low educational group and manual workers among men aged 30-59 years also showed an increased proportion of high-risk drinking. Inadequate physical activity levels also increased among men between 2019 and 2020 in those aged 30-39 years, non-single households, urban residents, and the upper-middle-income group.

CONCLUSIONS

In the first year of the COVID-19 pandemic, Korean men’s high-risk drinking and inadequate physical activity levels increased. In addition to social efforts to reduce the spread of infectious diseases, active measures to positively change health behaviour are needed.

Abstract Summary PDF: Abstract
OBJECTIVES
The aim of this study was to identify the stepping cadence patterns in Korean adults by using objectively measured accelerometer data to analyze the time spent in each cadence category by sex and age.
METHODS
During the 2014-2015 Korean National Health and Nutrition Examination Survey, 1,703 males and females aged 19-64 years provided at least 1 valid day of data (wearing an accelerometer ≥ 10 hr/d). The mean cumulative time and percentage per day in 8 cadence categories (0, 1-19, 20-29, 30-59, 60-79, 80-99, 100-119, and ≥ 120 steps/min) by sex and age group were calculated.
RESULTS
Cumulative time and percentage per day decreased across the incremental cadence categories. Participants spent 360.08± 2.56 min/d in the non-movement cadence category and 361.50± 2.28 min/d in the incidental movement cadence category. However, they spent only about 18.1 min/d (2.1%) at ≥ 100 steps/min. Males spent significantly more time in the cadence categories of sporadic movement, purposeful steps, slow walking, and medium walking, but the other categories, except for brisk walking, had higher values in females (p< 0.001). The older age group spent less time in non-movement cadence categories, and the youngest and oldest groups spent more time at a higher cadence (≥ 100 steps/min) than the other age groups. Similar patterns were found in a subgroup analysis by sex.
CONCLUSIONS
Korean adults spent most of their time at a low cadence and only a few minutes at a high cadence (≥100 steps/min); this trend was consistent across sex and age groups.; Summary

Abstract

OBJECTIVES
This study was performed to identify the effect of physical activity at work on obesity and to analyze the contribution of socioeconomic factors and health behaviors to this association, which has been relatively little studied.

METHODS

From the Korean National Cancer Center Community Cohort, a total of 5,587 adults (2,125 men; 3,462 women) aged more than 30 years living in rural areas were enrolled. Information on socio-demographic factors, health behaviors, and body mass index was gathered using face-to-face interviews and measurements of height and weight.

RESULTS

Inverse associations were identified between vigorous-intensity physical activity at work and obesity in both men and women, while no association was found between vigorous-intensity physical activity during leisure time and obesity. High household income was independently associated with a lower risk of obesity among those who had low levels of vigorous-intensity physical activity at work. Vigorous physical activity at work showed an inverse association with obesity in rural areas where heavy manual labor is common.

CONCLUSIONS

Our findings indicate the necessity to account for various types of physical activity to improve the assessment and prevention of obesity.

Abstract

OBJECTIVES
The purpose of this study was to compare moderate-to-vigorous physical activity (MVPA) with walking in terms of associations with metabolic syndrome components in Korean older adults.

METHODS

Data on 1,388 older adults (age ≥65 years) from the Korea National Health and Nutrition Examination Survey 2018 were analyzed in this study. MVPA time and walking time per week were used as physical activity variables and blood pressure, waist circumference, glucose, high-density lipoprotein cholesterol, and triglyceride levels were analyzed as metabolic syndrome components. Partial correlations, analysis of covariance, and multinomial logistic regression were used for statistical analysis after adjusting for age, sex, smoking, and alcohol consumption.

RESULTS

High-density lipoprotein cholesterol levels were significantly higher in the low MVPA/high walking and high MVPA/ high walking groups than in the low MVPA/low walking group. Triglyceride levels were significantly lower in the high MVPA/ high walking group than in the low MVPA/low walking and low MVPA/high walking groups. Engaging in <150 min/wk of MVPA increased the likelihood of abnormal blood pressure and metabolic syndrome by 1.81 times and 1.89 times, respectively, compared to ≥150 min/wk of MVPA. Engaging in <180 min/wk of walking raised the likelihood of having abnormal highdensity lipoprotein levels by 1.32 times compared to ≥180 min/wk of walking.

CONCLUSIONS

Not only MVPA but also walking was significantly associated with metabolic syndrome components in Korean older adults. Considering older adults’ preferences and exercise barriers, walking should be considered as an essential component of physical activity guidelines to prevent chronic diseases in older adults.

Abstract

OBJECTIVES
This study was conducted to identify and characterize the barriers and motivations to physical activity (PA) for elderly adults in Iran and other countries.

METHODS

We searched 6 databases (PubMed, Embase, Scopus, Web of Science, Magiran, and the Scientific Information Database) from 2000 to the November 2017, using “aged 60 and over,” “physical activity” or “exercise,” and “motivator” and “barrier” as keywords. Two reviewers independently performed the search, screening, and quality assessment of the studies.

RESULTS

In total, 34 papers were finally included in the study. The most important barriers, based on the frequency of factors, included physical problems, having no companions, and physical barriers to walking. The motivators included improving one’s physical condition, being social, and suitability of the physical environment.

CONCLUSIONS

Important motivators and barriers to PA were more closely related to intrapersonal factors than to the interpersonal and environmental domains. The barriers and motivators to PA in the elderly were not markedly different between Iran and other countries. Therefore, a general strategy could be designed to improve PA in the elderly.

Abstract

OBJECTIVES
This study investigated physical activity (PA) participation based on demographic, physical, and psychological variables in Korean adults.

METHODS

Participants were divided into four groups (combined, aerobic only, resistance only, and neither) based on meeting the PA guidelines using moderate and vigorous PA time and resistance exercise frequency from the Korea National Health and Nutrition Examination Survey 2017. The association between meeting the PA guidelines and demographic, medical, fitness, lifestyle, and psychological variables were analyzed using complex samples crosstabs and a general linear model.

RESULTS

Of the 5,820 Korean adults, 66.0% did not meet any of the guidelines. Among demographic factors, sex, age, marital status, income, education level, occupation, and employment status were associated with meeting the PA guidelines. Chronic disease prevalence, weight, waist circumference, body mass index, diastolic blood pressure, glucose, high-density lipoprotein and triglyceride levels, hand-grip strength, resting heart rate, and family history of chronic disease in the medical and fitness variables; frequency of drinking and eating breakfast, total calorie, water, protein, and fat intake in the lifestyle variables; and perceived stress, depression, suicidal thoughts, and quality of life in the psychological variables were associated with meeting PA guidelines.

CONCLUSIONS

Most Korean adults participate in insufficient PA. Moreover, individuals who are socially underprivileged, have low-income or poor physical and mental health conditions participated in relatively less PA. Our findings suggest that government and individual efforts are required to increase PA and resolve health inequality in Korean adults.

Abstract

OBJECTIVES
While gender differences in physical activity (PA) have been reported, their origin is not well understood. The present study aimed to identify factors contributing to this disparity.

METHODS

This was a population-based cross-sectional study based on the 2011 surveillance of risk factors of non-communicable diseases that was conducted among Iranian adults. Multi-staged sampling was performed to obtain the required study sample. The primary outcome was gender differences in the prevalence of sufficient physical activity (SPA). Total physical activity (TPA) was calculated as metabolic equivalents (MET) per minute during a typical week, as recommended by the World Health Organization. On this basis, achieving 600 MET-min/wk or more was defined as SPA. The nonlinear Blinder-Oaxaca decomposition technique was used to explain the disparity.

RESULTS

The predicted gap was 19.50%. About one-third of the gap was due to differences in the level of observable covariates. Among them, work status contributed the most (29.61%). A substantial portion of the gap remained unexplained by such differences, of which about 40.41% was related to unobservable variables. The differential effects of standard of living, ethnicity, and smoking status made the largest contribution, accounting for 37.36, 35.47, and 28.50%, respectively.

CONCLUSIONS

Interventions to reduce the gender gap in PA should focus on increasing TPA among housewives and women with chronic diseases, as well as those with a higher standard of living. In addition, it is essential to explore the impact of ethnicity and smoking status on women’s TPA in order to promote health.

Abstract

OBJECTIVES
Although the effect of physical activity (PA) on the incidence of atrial fibrillation (AF) has been studied, contradictory results have been reported. Such discrepancies may reflect the different effects of various types of PA upon AF, as well as gender interactions. Therefore, we aimed to evaluate the associations of PA types (total, moderate/vigorous, and intentional), as well as walking pace, with AF risk in men and women.

METHODS

Using the Multi-Ethnic Study of Atherosclerosis Typical Week Physical Activity Survey, 3 PA measures and walking pace were calculated among 6,487 men and women aged 45-84 years. The incidence of AF over approximately 11 years of followup was ascertained. The association of each PA measure and walking pace with AF incidence was estimated using multivariable Cox proportional hazard models. An extended Cox model with Heaviside functions (hv) of time was used to estimate the effects of time-varying covariates.

RESULTS

During 11 years of follow-up (49,557 person-years), 242 new AF cases occurred. The incidence rate of AF was 48.83 per 10,000 person-years. The proportional hazard (PH) assumption for total PA among women was not met; hence, we used the hv to calculate the hazard ratio. Total PA in women in the hv2 analysis was negatively associated with AF in all 3 models, although for hv1 no significant association was observed. The PH assumption for walking pace among men was not met, and none of the hv showed a statistically significant association between walking pace and AF in men.

CONCLUSIONS

These results suggest that PA is inversely associated with AF in women.

Abstract PDF: Abstract
Understanding the spread of infections is of vital importance in the control of epidemics and the development of proper policies toprevent infectious diseases. Theory and techniques have been developed for the study of both the evolution of diseases with individual people and the transmission of infections through populations. From broad theoretical issues to specific practical problems, the mathematical modeling studies of infectious diseases have provided great insight to solve the mechanisms of disease spread and to predict the course of epidemics. Emerging and reemerging infectious diseases have attracted widespread concern in Korea. While preparing the influenza pandemic plan in 2004, we developed a model of the new influenza pandemic to estimate the number of cases and deaths, the shortage of medical resources, and the effect of interventions such as isolation and vaccination. Based on this model, we constructed a possible pandemic scenario of the emerging virus, and designed a table-top exercise for public health officials and related administration staff. On March 30th, 2005, the exercise was performed and the results were evaluated as successful. In the case of bioterrorism, a model of small pox epidemic was developed in 2005 to examine the speed of the disease spread in the population and to evaluate the intervention effects in a Korean city. The simulation results were also helpful to form a guideline to prepare for a small pox epidemic. These two experiments confirmed the usefulness of epidemic modeling in Korea.; Summary

OBJECTIVES
To compare eating behavior according to the shift work and to find the factors associated with the abnormal eating behavior in university hospital's nurses.
METHODS
For this assessment, a cross-sectional study was conducted with 300 university hospital's nurses. Nurses were questioned with self-reported questionnaire forms. After excluding cases with incomplete data, 276 cases are enrolled in the study. To find the factors associated with the abnormal eating behavior, we conducted multiple logistic regression analysis.
RESULTS
The proportions of shift work nurses were 63.77%(176 cases). The proportions of abnormal eating behavior among shift work nurses were 22.73%(40 cases), but only 6.00%(6 cases) among non-shift work nurses had the abnormal eating behavior. Considering the shift work period, the proportions of abnormal eating behavior were 31.25%, 22.92% and 17.50% in case of shift work period were less than 1 year, 1~3 years and more than 3 years, respectively. The abnormal eating behavior was associated with having shift work, doing exercise, more weekly working hours, being on a diet and having perception of overweight. But age and body mass index were not influenced the abnormal eating behavior.
CONCLUSIONS
In this study, we found that the factors associated with the abnormal eating behavior are the shift work, exercise, weekly working hours, perception of overweight and diet.; Summary

Abstract PDF: Abstract
To investigate the association of individual health behaviors with imune response against tumor or viral infection, peripheral blood lymphocytes of 185 healthy males in aged from 35 to 44 years for natural killer(NK) cell activity, frequencies of lymphocytes subsets and proliferation response of T and B cell. NK cell activity was determined by Cr release activity assay and lymphocytes subsets were counted using surface antigens(CD4, CD8, CD56) by flow cytometry. The responsiveness of T and B were measured as proliferation stimulated by mitogens. Subjects were classified into four distinct lifestyle patterns, health promotive lifestyle, passive lifestyle, fitness lifestyle and hedonic lifestyle from information on their health behaviors(cigarette smoking, alcohol consumption, and physical activity). Health promotive lifestyle had the highest NK cell activity(Lu30/10(6)CD56) which was significantly higher than hedonic lifestyle)p<0.05). The responsiveness of T cell was significantly lower in passive lifestyle and hedonic lifestyles compared to health promotive lifestyle and fitness lifestyles(p<0.05). However, there was no significant difference in the responsiveness of B cell, CD4, and CD8 among four lifestyles. This cross-sectional study showed the NK cell activity in individuals with desirable health behaviors was lower. The variation of immunity among individuals was not considered in this study, hence the intervention study reflection individual variations is recommended.; Summary
