ABSTRACT

Purpose@#The purpose of this study was to identify the associations between type of moderate-vigorous physical activities (MVPA) and psychological stress in South Korean, based on the Korean Genome and Epidemiology Study. The subjects of this study were 2,891 Korean men and women aged 40 to 69, who completed health examination from 2011 to 2012. @*Methods@#The type of MVPA was measured by using self-reported physical activity questionnaire. A high psychological stress was determined by scoring Psychological Well-being Index Short Form (≥ 27). Logistic regression analysis, adjusting other confounding factors, was conducted to identify the association of type of MVPA level with psychological stress (p< 0.05). @*Results@#Participants who leisure-related MVPA of ≥ 150 min/week was less likely have to high psychological stress than < 150 min/week (odds ratio [OR], 0.72; 95% confidence interval [CI], 0.57–0.92). From the analysis of gender, leisure-related (OR, 0.50; 95% CI, 0.35–0.72) and work-related (OR, 0.63; 95% CI, 0.41–0.97) MVPA of ≥ 150min/week were associated with low psychological stress in men, but women was not significantly associated. From the analysis of age, leisure-related MVPA of ≥ 150 min/week were associated with low psychological stress in middle age group (OR, 0.70; 95% CI, 0.53–0.92), but elderly group was not significantly associated. Differences inpsychological stress OR according to type of MVPA time were observed about classification of occupations. @*Conclusion@#High level of leisure related physical activity were independently associated with reducing risk for psychological stress. Also, encouraged MVPA by gender, age, classification of occupations could help to improve psychological stress levels in middle-aged or older adults.

ABSTRACT

Purpose@#Our primary aim was to elucidate the association between relative grip strength levels and the risk of developing diabetes, utilizing longitudinal data. @*Methods@#A total of 1,935 participants in this study comprised general adults aged 51 to 81 years, who had engagedin the survey both in 2013–2014 and during the subsequent follow-up in 2019–2020. The criteria for diagnosingdiabetes included receiving a diabetes diagnosis and treatment. grip strength was converted into relative grip strength by dividing it by body mass index. To validate the relationship between the interaction of relative grip strength and resting heart rate and its impact on risk of developing diabetes, a proportional hazards Cox regression model was used.Subsequently, we computed the hazard ratio (HR) and 95% confidence interval (CI) for risk of developing diabetes. @*Results@#After adjusting for various confounding variables, we observed a significant 46% reduction in the risk of developing diabetes in the high relative grip strength group compared to the low relativegrip strength group (HR,0.54; 95% CI, 0.36–0.80). However, upon additional adjustment for waist circumference, no significant findings couldbe yielded. Furthermore, we found significant differences the relationship between relative grip strength, resting heart rate, and the risk of developing diabetes among different groups. @*Conclusion@#This study investigates the relationship between relative grip strength and incidence of diabetes, attributed to the accumulation of body fat. Notably, both resting heart rate and relative grip strength emerge as predictive indicators for assessing the risk of diabetes development.

ABSTRACT

Purpose@#The purpose of this study was to investigate the association between estimated cardiorespiratory fitness (eCRF) and insulin resistance in Korean adults, and to compare this association through sex and age-specific analyses. @*Methods@#A total of 13,405 adults aged 19 years and older (male, 5,869; female, 7,536) were analyzed using data from the Korea National Health and Nutrition Survey (KNHANES) for the years 2019 to 2021. eCRF was analyzed by dividing it into quartiles using the estimation equation based on age, sex, body mass index, waist circumference, smoking status, resting heart rate, and self-reported physical activity level. Insulin resistance was measured to calculate the HOMA-IR. Logistic regression was used to predict the odds ratio (OR) and 95% confidence interval (CI) of the relationship between the two variables, with adjustment for potential confounders. @*Results@#The results showed a stronger association between fitness level and insulin resistance. Based on the first quartile (reference group), the lower the cardiorespiratory fitness level, the higher the OR. In male subjects, the lowest quartilehad an OR of insulin resistance 17.65 (95% CI, 13.76–22.64). For female subjects, the lowest quartile had an OR of insulin resistance 7.96 (95% CI, 6.37–9.94). These results indicate a strong inverse relationship between cardiorespiratoryfitness and insulin resistance and younger groups exhibited significantly higher ORs in age-specific ORs. @*Conclusion@#The analysis results demonstrated that increasing cardiorespiratory fitness levels can significantly impact insulin sensitivity and reduce insulin resistance risk.

ABSTRACT

Purpose@#This study aimed to investigate the association between relative muscle strength and serum hemoglobin levels. @*Methods@#In this study, 3,234 adults living in rural areas were surveyed from 2007 to 2014 and the data was analyzed on 1,987 adults. Anemia (< 12 g/dL for women and < 13 g/dL for men) was defined by examining serum hemoglobin concentration. Muscle strength was measured by using Takei dynamometer about grip strength and leg strength.To identify the association between relative strength and anemia, odds ratio (OR) and 95% confidence interval (CI) were calculated using logistic regression analysis (p< 0.05). @*Results@#As confounding variables were adjusted, relative leg strength (high level: OR, 0.55; 95% CI, 0.34– 0.88) and relative grip strength (middle level: OR, 0.57; 95% CI, 0.37– 0.88; high level: OR, 0.50; 95% CI, 0.30– 0.84) were associated with OR of anemia risk. Relative grip strengths were significantly associated with risk of anemia in the ≥ 65-year age group (middle level: OR, 0.43; 95% CI, 0.23– 0.78; high level: OR, 0.32; 95% CI, 0.14– 0.72), but not in the < 65-year age group. Also, ≥ 65-year age group, who have both high relative grip strength and high relative leg strength (OR, 0.44; 95% CI, 0.21– 0.93) or only high relative grip strength (OR, 0.41; 95% CI, 0.18– 0.96), was only significantly associated with the prevalence of anemia. @*Conclusion@#Improvement of relative muscle strength is a key factor that can lower the risk of anemia and it is recommended in order to reduce the health risk of elderly life.

ABSTRACT

Purpose@#The purpose of this study was to examine the association between the levels of sedentary time, physical activity, and obesity in Korean older adults. @*Methods@#A cross-sectional analysis was performed on 1,396 Korean older adults aged 65 to 80 years from the Korea National Health and Nutrition Examination Survey 2018. Complex samples logistic regression was used to examine the relationship between the levels of sedentary time, physical activity, and obesity. @*Results@#The high sedentary group (≥ 8 hours/day) had significantly greater odds of having obesity than the low sedentary group (< 8 hours/day). But there was no statistically significant difference in odds of having obesity between the high active group (≥ 600 metabolic equivalent of task [MET]-minute/week) and the low active group (< 600 MET-minute/week). The high sedentary/low active group had significantly greater odds of having obesity than the low sedentary/high active group and the low sedentary/low active group. But there was no statistically significant difference in odds of having obesity compared to the high sedentary/high active group. @*Conclusion@#Higher sedentary time (≥ 8 hours/day) was associated with a higher risk of having obesity, independent of meeting higher physical activity level (≥ 600 MET-minute/week) in Korean older adults.

ABSTRACT

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 physical activity between 10-minute bouts and total bouts were also compared.METHODS: Data originated from the Korea National Health and Nutrition Examination Survey. Logistic regression was used to predict cardiovascular disease risk from physical activity levels.RESULTS: Self-reported physical activity could not significantly predict the odds of having cardiovascular risk. However, the insufficiently active group classified according to the total-bout physical activity had significantly greater odds of having hypertension or prehypertension (odds ratio [OR], 1.35; 95% confidence interval [95% CI], 1.00–1.82), diabetes mellitus (OR, 1.77; 95% CI, 1.01–3.19), and dyslipidemia (OR, 1.65; 95% CI, 1.17–2.36) than the highly active group. Regarding the 10-minute bout physical activity, the inactive group had significantly greater odds of having only hypertension or prehypertension (OR, 1.67; 95% CI, 1.02–2.76) than the highly active group.CONCLUSION: Total-bout physical activity measured using an accelerometer could significantly predict the cardiovascular disease risk compared to 10-minute bout physical activity. However, self-reported physical activity could not significantly predict the cardiovascular disease risk.

ABSTRACT

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 and Nutrition Examination Survey 2014–2015. @*Methods@#The participants included in this study volunteered to wear accelerometer (n=1,407). Ordinal logistic regression was used to examine the relationship between sedentary time or sedentary breaks and cardiovascular disease risk factors. Odds ratios and 95% confidence intervals were calculated for the relationship. Covariates were sex, age, educational status, alcohol, smoking, socioeconomic status, body mass index, calorie intake, physical activity, and accelerometer wear time. @*Results@#The group with the most sedentary time had significantly greater odds of having dyslipidemia (odds ratio, 2.47; 95% confidence interval, 1.54–3.94) compared to the least. There were no other significant relationships between sedentary behavior (sedentary time, sedentary break) and risk factors. @*Conclusion@#The only significant relationship found in this study was that between sedentary time and dyslipidemia.

ABSTRACT

BACKGROUND: Catastrophic health expenditure (CHE) occurs when medical expenditure of a household passes over a certain ratio of household income. This research studied the effect of gender on CHE based on Korea Health Panel data. METHODS: This study implemented binary logistic regression model to figure out whether gender affects CHE and how different gender groups show pattern of CHE process. With gender, age, marital status, income level, economic activity, membership of private insurance, existence of chronic disease, and self-rated health were included in the model. RESULTS: Results showed that females faced CHE 1.5 times more than males (odds ratio, 1.241). Also, main determinants of CHE in female groups were marital status, while age and economic activity status were significant in male groups. Subgroup analysis displayed that married female under 35 years old are located in intersectionality of CHE including pregnancy and delivery, multiple health risk behaviors, mental stress, and relatively vulnerable social status due to lower income. Meanwhile, both gender above 50 years old faced remarkably high chance of CHE, which seems to be caused by complex health risk behaviors and chronic diseases. CONCLUSION: Such results implied not only that gender is an important determinant of CHE, but also other determinants of CHE differ according to gender, which suggests a necessity of gender-based CHE support and rescue policy.

ABSTRACT

The objective of this study was to assess dietary habits and nutrition knowledge of elementary school students who use community food-service centers according to family type. The subjects were comprised of 147 individuals in low-income households, aged from 7 to 12 years, and who consumed free meals at community welfare centers or at local children's centers in Seoul and Kyunggi-do, Korea. Dietary habits and dietary intake were obtained using 24-hr recall. Children in low-income single parent families skipped breakfast more frequently than children in low-income married parent families. No difference in nutrition intake or dietary habits was observed between children in low-income single parent families and children in low-income married parent families. More interest and financial support of the government are required to develop nutrition education and food assistance programs for children in low-income single parent families.

ABSTRACT

Prevalence of childhood obesity is increasing significantly worldwide due to energy imbalance perhaps stemming from undesirable dietary behavior and physical activity level. The objective of the study was to examine the effects of physical activity level on nutritional status in elementary school students. The subjects were comprised of 287 elementary school students between 4th and 6th grades in Seoul, Korea. The level of physical activity was scored with a modified Godin leisure-time exercise questionnaire and was categorized as active, moderately active, and sedentary. Dietary intakes were obtained using a 24-hour food recall method. An analysis of variance (ANOVA) was conducted to test for global significant differences of nutrient intakes by physical activity level. Boys were more active than girls. Daily intakes of energy in moderately active boys were significantly higher than in the sedentary group, but intakes of calcium and iron in moderately active boys were lower than active boys. For girls, physical activity level did not affect nutrient density at all. Intakes of calcium, vitamin C, and folate for both boys and girls were below 50% of recommended intake. Physical activity did not affect nutrient density and our participants were exposed to nutritional imbalance. Therefore, the results suggest that nutrition education regarding balanced diet and optimum physical activity is required for children's health and growth.

ABSTRACT

We performed this study to examine lifestyle patterns and dietary behavior based on the level of Internet addiction of Korean adolescents. Data were collected from 853 Korean junior high school students. The level of Internet addiction was determined based on the Korean Internet addiction self-scale short form for youth, and students were classified as high-risk Internet users, potential-risk Internet users, and no risk Internet users. The associations between the students' levels of Internet addiction and lifestyle patterns and dietary behavior were analyzed using a chi-square test. Irregular bedtimes and the use of alcohol and tobacco were higher in high-risk Internet users than no risk Internet users. Moreover, in high-risk Internet users, irregular dietary behavior due to the loss of appetite, a high frequency of skipping meals, and snacking might cause imbalances in nutritional intake. Diet quality in high-risk Internet users was also worse than in potential-risk Internet users and no risk Internet users. We demonstrated in this study that high-risk Internet users have inappropriate dietary behavior and poor diet quality, which could result in stunted growth and development. Therefore, nutrition education targeting high-risk Internet users should be conducted to ensure proper growth and development.
