Summary: This study investigated the daily amounts of time spent sitting and frequency of breaks from sitting for Korean adults and identified their sociodemographic, environmental, and health behavioral correlates. The results showed that sitting time was associated with gender, age, occupation, place of residence, education level, smoking status, weight, physical activity, and sleep duration. Fewer breaks from sitting were associated with gender, marital status, age, occupation, place of residence, smoking status, and weight, while higher education level and physical inactivity were associated with more frequent breaks from sitting.

Summary: This study aimed to explore the relationship between work-related physical activity and depression among South Korean workers. The findings revealed that individuals engaged in work-related physical activity had higher levels of depressive symptoms, and high-intensity work-related physical activity significantly increased depression. Additionally, workers who engaged in both work-related and leisure physical activities had lower levels of depression compared to those who only engaged in work-related physical activities.

Summary: This study aimed to establish normative values for hand grip and pinch strength among children aged 6 to 18 years in Saudi Arabia. A total of 616 participants from different regions in Saudi Arabia were included. The results showed that hand grip and pinch strength increased with age regardless of hand preference, and boys had significantly higher grip strength than girls in all age groups.

Summary: The study aimed to identify stepping cadence patterns in Korean adults using accelerometer data, finding that most time was spent at low cadence levels with only minimal time spent at high cadence levels, a trend consistent across different sex and age groups. Differences were observed in cadence categories between males and females, as well as among different age groups.

Summary: This study investigated the association between protein intake and grip strength in the South Korean population. It found that women with low grip strength had lower total and animal protein intake, as well as protein intake from legumes, fish, and shellfish, compared to those with normal grip strength. Adequate protein intake above the estimated average requirement and protein intake from legumes should be encouraged to prevent low grip strength, especially in elderly women.

Summary: This study used data from the Eighth Korea National Health and Nutrition Examination Survey to investigate the relationship between physical activity (PA) and health-related quality of life (HR QOL). The findings showed that individuals who engaged in weekly PA, leisure-related PA, or moderate-intensity PA had higher HR QOL compared to those who did not engage in PA. This study confirmed a significant positive correlation between PA and HR QOL.

Summary: This study examined the odds ratio for the association between working hours and obesity in Korean male wage workers, finding that those working 50-59 hours per week and 60 hours or more had higher odds of obesity compared to those working less than 40 hours. Furthermore, sleep was found to mediate the relationship between working hours and body mass index.

Summary: This study found that lower serum vitamin E levels were associated with decreased hand grip strength in older men living in the community, but not in women. Individuals with the lowest vitamin E levels had higher odds of low hand grip strength, independent of various other factors. Further validation of these findings is needed.

Summary: This study investigated the nutritional intakes and treatment regimens of Korean patients with type 2 diabetes who were aware of their condition. The results showed that the unaware group had higher intake of certain nutrients, higher rates of smoking and heavy drinking, and lower fiber intake. Diabetes control was better in the high income group.

Summary: Inadequate nutritional intake is common among elderly individuals, and the effects of multi-vitamin and mineral supplements (MVMS) in the Korean elderly are not well known. This study investigated the nutrition-improving effects of a single MVMS. Analysis of participants in the Korea National Health and Nutrition Survey showed that intake of MVMS with food was associated with lower rates of nutrient inadequacy compared to the food-only group. These findings suggest that micronutrient deficiency is prevalent among the Korean elderly and can be improved by MVMS intake.

Summary: In Korean older adults with diabetes, women showed lower muscle mass index and muscle strength, higher prevalence of sarcopenia and frailty, and decreased physical performance compared to men. Reduced muscle mass index and handgrip strength may be associated with diabetes.

Summary: This study found an association between perceived neighborhood environmental factors and sarcopenia among urban-dwelling older adults aged 70-84. Certain neighborhood characteristics, such as lack of public transportation access and poor recreational facilities, were linked to increased likelihood of sarcopenia. Improving neighborhood environmental strategies may help prevent sarcopenia in this population.

Summary: This study investigated the usefulness of time orientation as an easy diagnostic tool for suspecting mild cognitive impairment (MCI) or depression, finding that orientation to the year had the highest diagnostic sensitivity for both conditions. Asking about the current year may be helpful in identifying MCI or depression in community and primary care settings among older adults.

Summary: This study aimed to develop multiple biomarker panels to predict sarcopenia in older adults and explore its association with sarcopenia incidence. By analyzing data from 1,021 older adults, 8 optimal biomarkers were selected to develop a multi-biomarker risk score, which showed better discrimination for sarcopenia than single biomarkers according to receiver operating characteristic analysis. During a two-year follow-up, the incidence of sarcopenia was found to be positively associated with the continuous multi-biomarker risk score. In conclusion, the multi-biomarker risk score can effectively predict sarcopenia and its incidence in older adults.

Summary: As life expectancy increases worldwide, the prevalence and disease burden of diabetes in older adults are also increasing. This study aimed to investigate sex differences in the reciprocal relationship between glycemic control and depressive symptoms in older adults with diabetes. The results showed that early glycemic control and depressive symptoms were significant factors influencing later glycemic control and depressive symptoms. The relationship between glycemic control and depressive symptoms varied by sex.

Summary: This study compared serum creatinine- and cystatin-C-based indices as screening biomarkers for sarcopenia in community-dwelling older adults. The results showed that pSMI and TBMM accurately determined sarcopenia, with pSMI strongly associated with a decreased risk of sarcopenia. These findings suggest pSMI as a potential biomarker for sarcopenia screening.
