BACKGROUND: Post-stroke disability diminishes the physical activity (PA) level of survivors, potentially affecting their long-term prognosis. This study endeavors to explore the correlation between daily PA level and the all-cause mortality in patients with a history of stoke in the United States. METHODS: Data of stroke survivors were sourced from the National Health and Nutritional Examination Survey (NHANES) 2007-2018. The population was stratified into three groups based on their PA level. Kaplan-Meier method with log-rank tests for significance was used for survival analysis. Weighted Cox proportional hazards regression models were employed to estimate the hazard ratios (HRs) for all-cause mortality. Subgroup analysis was conducted to strengthen the results. RESULTS: A total of 1395 participants were recruited, comprising 679 males and 716 females, with a median age of 68 years. Based on their PA levels, 779 individuals were classified as inactive, 156 as insufficiently active, and 460 as sufficiently active. Following a median observation period of 59 months, there were 476 recorded deaths, with 349, 47, and 80 cases in the three respective groups. Compared to the inactive group, the HRs and 95% confidence intervals (CIs) for all-cause mortality in participants who were insufficiently active and sufficiently active were 0.58 (0.40, 0.84) and 0.47 (0.33, 0.67), respectively. The Kaplan-Meier curve revealed a significant difference in overall survival between the three groups, as confirmed by the log-rank test (P < 0.0001). Subgroup analysis further validated our results and demonstrated that the protective impact of PA on stroke prognosis varies according to distinct characteristics. CONCLUSIONS The results indicate that increased levels of PA are associated with a protective effect on long-term mortality among stroke survivors. Further prospective longitudinal studies are necessary to elucidate the optional PA level and special exercise guideline targeting this population.

Objective: This study was aimed at examining the trends and correlates of physical activity (PA) and sedentary behaviors among Chinese children. Methods: A total of 4,341 subjects (6,936 observations) aged 6-17 years who participated in the China Health and Nutrition Survey (2004-2015) were included. Of the subjects, 41% participated in the survey twice or more. Random-effects ordinal regression models and repeated-measures mixed-effects models were used to examine the PA trends. Quantile regression models were applied to examine the factors influencing PA and sedentary behaviors. Results: From 2004 to 2015, the prevalence of physical inactivity among Chinese children aged 6-17 years increased by 5.5% [odds ratio ( Conclusions A declining PA trend among Chinese children aged 6-17 years was observed from 2004 to 2015, and certain subgroups and geographical areas are at higher risk of physical inactivity.

Objective: This study aimed to determine the independent and joint associations of sedentary time (ST) and physical activity (PA) with metabolic syndrome (MetS) and its components among Chinese adults. Methods: The study analyzed data from 4,865 adults aged ≥ 18 years who participated in the 2009 and 2015 China Health and Nutrition Surveys (CHNS). Four types of leisure ST and three types of PA self-reported at baseline were collected. Multivariable logistic regressions were used to determine the independent and joint associations of ST and PA with the odds of MetS or its components. Results: For independent effects, higher levels of television time and total leisure ST was associated with higher MetS risk [odds ratio ( Conclusions MVPA and total PA have independent preventive effects, and sedentary behavior (mainly watching TV) has an unsafe effect on MetS and its components. Strengthening the participation of MVPA and combining the LPA to replace the TV-based ST to increase the total PA may be necessary to reduce the prevalence of MetS in Chinese adults.

OBJECTIVE: This study aimed to describe frequency and quantity of total dairy consumption of Chinese children and adolescents and explore the associations between dairy consumption and nutrition status, including stunting, wasting, overweight, and obesity. METHODS: Participants included 28,250 children and adolescents aged 6-17 years old. A food frequency questionnaire (FFQ) including 100 kinds of food was used to collect information about frequency and quantity of dairy consumption. Determination of stunting was with a height cutoff value for age and gender, and determination for wasting, overweight, and obesity was with BMI for age and gender. RESULTS: Of the total sample, 36.1% of children aged 6-17 reported consuming dairy food more than once per day (⪖ 1/day). The average total dairy intake of all the participants was 126.7 g/day. For boys, dairy consumption had an inverse correlation with stunting and wasting after controlling for confounders. For girls, dairy consumption was negatively associated with stunting and obesity after controlling for confounders as above. CONCLUSION Dairy consumption in Chinese children and adolescents was relatively lower than that in developed countries, and was negatively associated with stunting and wasting for boys and with stunting and obesity for girls.

PURPOSE: The purpose of this study was to investigate the relationship between obesity, body image perception, and weight control for obesity management in adult women. METHODS: The subjects of this study were 3,617 women aged over 19 years, who participated in the Seventh Korea National Health and Nutrition Examination Survey 2016. Data were analyzed through complex sampling design data analysis. RESULTS: Right body image perception according to obesity was apparent between 70.6–81.7% of women and 76.5% of women with abdominal obesity perceived that they were normal. Obese women performed more weight control than non-obese women. Women with only abdominal obesity performed less weight control than non-obese women, and 47.3% of them performed weight control. Women who perceived themselves as obese performed more weight control than women who perceived themselves as non-obese (odds ratio, 2.08; confidence interval, 1.69–2.57), but body mass index was not observed to be associated with weight control. CONCLUSIONS: Education on abdominal obesity should be provided to increase awareness about abdominal obesity and its effective management, especially in women with only abdominal obesity. In addition, interventions for right body type perception should be provided for proper weight control along with prevention and management of obesity.

PURPOSE: This study was to identify health behavior, health service use, and health related quality of life of adult women in one-person and multi-person households. METHODS: It was used data from the 7th Korea National Health and Nutrition Examination Survey (KNHANES VII-2017). Subjects were 2,522 women with age of 19 to 64 years in 2017. Complex sampling design and data analysis were performed using SPSS 20.1. RESULTS: Women in one-person households had higher rates of alcohol drinking (χ²=13.77, p=.003), smoking (χ²=16.07, p=.001), unmet medical care (χ²=8.77, p=.004) and non-practice of cancer screening (χ²=13.77, p=.003) compared to women in multi-person households. Health-related quality of life was also lower for women in one-person households (t=−2.46, p=.015). Factors affecting health-related quality of life in one-person households were household income, job status, and unmet dental care, having 32.4% explanatory power. One-person household women with low incomes, no jobs, and unmet dental care showed low health-related quality of life. In comparison, factors affecting health-related quality of life of women in multi-person household women were age, education level, unmet medical care, and unmet dental care, having 10.4% explaining power. Women in multi-person households with age of 60–64, low education level, unmet medical care, and unmet dental care showed low health-related quality of life. CONCLUSION: Health promotion strategies should be developed based on unique understanding of social, economic, and health of adult women in one-person and multi-person households.

OBJECTIVES: This study identifies associated factors of ischemic heart disease (IHD) among post-menopausal Korean women at the biomedical (age, family history of hypertension, dyslipidemia, type 2 diabetes mellitus, or cerebro-cardiovascular disease, body mass index, and metabolic syndrome), biosocial (socioeconomic status and educational level), and psychosocial levels (stress, depression, smoking, binge alcohol consumption, and physical activity). METHODS: This study used a cross-sectional design with secondary data analysis of the 2013–2016 Korean National Health and Nutrition Examination Survey. Data from 3,636 women were analyzed by logistic regression analysis using a complex sample procedure. RESULTS: Of the biomedical factors, older age [odds ratio (OR): 2.99, 95% confidence interval (CI): 1.87–4.80, p < 0.001], family history (OR: 2.29, 95% CI: 1.44–3.65, p = 0.001), and metabolic syndrome (OR: 1.93, 95% CI: 1.27–2.95, p = 0.002) were associated with IHD in post-menopausal women. Of the psychosocial factors, depression (OR: 2.56, 95% CI: 1.66–3.96, p < 0.001) and smoking (OR: 1.92, CI: 1.04–3.55, p = 0.038) were associated with IHD in post-menopausal women. CONCLUSION: These findings suggest that healthcare providers need to consider the contributing adverse effects of older age, family history, metabolic syndrome, depression and smoking when evaluating risk factors for IHD in post-menopausal women.

BACKGROUND AND OBJECTIVES: To investigate the relationship between hearing impairment and alcohol drinking patterns in South Korean adults. SUBJECTS AND METHODS: Data collection was performed by Korean National Health and Nutrition Survey from January 1 to December 31, 2012. Data analyses were performed from February 20 to March 3, 2018. Data from 3,860 adults 20 years of age or older without a history of malignancy or chronic otitis media in the Korean National Health and Nutrition Survey 2012 database who participated in the health questionnaires, and who had available results from otologic examinations that included pure tone audiogram, were included. Pure-tone average hearing thresholds were calculated at 500, 1,000, 2,000, and 4,000 Hz. Hearing loss was defined as a pure-tone average >40 dB in one or both ears. The Alcohol Use Disorder Identification Test was used to evaluate drinking statuses of subjects. Data were analyzed using the complex-sample χ²-test of independence and a complex-sample logistic regression analysis. RESULTS: Of the 29,954,319 individuals in the weighted cross-sectional study population, 15,106,040 (50.4%) were men and 14,848,098 (49.6%) were women. A total of 8.1% of men and 7% of women had hearing impairment. The degrees of drinking with appropriate, risky, and hazardous drinking habits were 58.2, 32.1, and 9.7% among men; and 76.4, 12.5, and 11.1% among women, respectively. Among men, the odds ratio of hearing loss increased by 2.506 times when comparing hazardous and appropriate drinking (confidence interval, 1.083 to 5.800, p=0.002). Moderate alcohol consumption (≤2 drinks per day) was not protective for hearing in either group. CONCLUSIONS: As hazardous drinking tends to coexist with hearing impairment in men, appropriate prevention and intervention strategies should be emphasized. A longitudinal study to investigate harmful drinking and the mechanism of hearing loss should be performed.

PURPOSE: The purpose of this study was to investigate osteoporosis prevalence and factors influencing health-related quality of life (HRQoL) among older Korean women with osteoporosis. METHODS: The study design was a retrospective study using secondary data analysis. Data for 1,355 women aged 65 and older from the Korea National Health and Nutrition Examination Survey (KNHANES) 2015 to 2016 were included. Linear regression analysis was conducted for influential factors on HRQoL, measured by the Euro Quality of Life-5D (EQ-5D). RESULTS: The prevalence of osteoporosis was 41.3% in older Korean women. The EQ-5D index score was lower in older women with osteoporosis (0.83) than those without osteoporosis (0.86). Lower HRQoL in older Korean women with osteoporosis was associated with lower household income, perceived health status as bad, comorbidity, activity restriction, and stress. CONCLUSION: The findings indicate that the prevalence of osteoporosis was high in older Korean women. In addition, healthcare professionals need to consider individual conditions such as economic status, perceived health status, other chronic diseases, activity restriction and level of stress for improvement of HRQoL in older Korean women with osteoporosis.

The purpose of this study was to examine the relationships between the nutrient intake and level of depressive symptoms. A total of 5,761 subjects with depression were selected for the main data analysis from a Korean National Health and Nutrition Examination Survey, KNHANES (2016), and were divided into low depressed and high depressed groups. The data were analyzed by descriptive analysis, χ2-test, logistic regression, and t-test using SPSS 24.0 statistics. The results revealed significant differences in the prevalence of depression according to sex (P < 0.001), age (P < 0.001), income (P < 0.001), and education (P < 0.001). Regarding the health behavior, higher stress levels (P < 0.001) and smoking habit (P < 0.001) appeared to be strongly associated with high levels of depression. On the other hand, the possibility of experiencing depressive symptoms was lower when the number of walking days per week was more than 3 days (P < 0.05), when the number of working days per week was more than 5 days (P < 0.01), and the rate of aerobic physical activity was higher. Based on the ‘Dietary Reference Intakes for Koreans 2015’, the subjects in the low depression group showed better intake of energy and 22 nutrients than the high depression group.
