Age-specific association between meal-skipping patterns and the risk of hyperglycemia in Korean adults: a national cross-sectional study using the KNHANES data.

BACKGROUND: Glucose metabolism regulation is influenced by age and meal skipping, although research on their interplay with hyperglycemia remains limited. This study aims to explore the intricate relationship between meal-skipping patterns and hyperglycemia risk across distinct age groups in South Korean adults. METHODS: Utilizing data from the Korea National Health and Nutrition Examination Surveys (KNHANES) conducted from 2013 to 2020, comprising 28,530 individuals aged 19 years and older, this study employed multivariable logistic regression models to examine the associations between meal-skipping patterns and the risk of hyperglycemia. RESULTS: Meal-skipping patterns were categorized into three groups: no skipping (NS), skipping breakfast (SB), and skipping dinner (SD). Age groups were defined as "young" (aged 19-44), "middle-aged" (aged 45-64), and "elderly" adults (over 65 years old). Among "young" adults, SB was associated with a 1.33-fold higher risk of hyperglycemia (OR = 1.33, 95% CI = 1.14-1.54) compared to NS. Conversely, in "elderly" adults, SD was linked to a 0.49-fold reduced risk (95% CI = 0.29-0.82) when compared to NS. Additionally, we observed that the Korean Health Eating Index (KHEI) scores, representing the quality of diet on a scale of 0 to 100, were consistently lower in SB compared to NS across all age groups. Intriguingly, specifically among the "elderly" group, this score was higher in SD compared to NS (p < 0.001). CONCLUSIONS: This study demonstrates age-specific variations in the association between meal-skipping patterns and the risk of hyperglycemia.

Sequential Mediation Effects of Organizational Support and Collaboration on Missed Nursing Care.

BACKGROUND: It is necessary to find ways to mediate the relationship between role overload and missed nursing care in settings where nursing staffing is inadequate. This study aimed to identify the single and multiple sequential mediation effects of organizational support, nurse-physician collaboration, and nurse-nurse collaboration on the relationship between role overload and missed nursing care. METHODS: Data were collected from 237 registered Korean nurses working in general wards in October 2022. The measures used were the modified role overload scale, nurse-physician collaboration scale, nurse-nurse collaboration scale, a short version of the Perceived Organizational Support Scale, and the modified Missed Nursing Care Scale. Data were analyzed using PROCESS macro in SPSS. A hypothesis test was performed using Model 81, proposed by Hayes, which includes serial multiple mediators. RESULTS: Organizational support, nurse-physician collaboration, and nurse-nurse collaboration showed a mediation effect on missed nursing care. Organizational support, nurse-physician collaboration, and nurse-nurse collaboration showed significant multiple sequential mediation effects on the relationship between role overload and missed nursing care. When the indirect effect sizes of nurse-physician collaboration were compared with those of nurse-nurse collaboration in both single and multiple sequential mediation paths, the indirect effect of nurse-physician collaboration was greater than that of nurse-nurse collaboration on the relationship between role overload and missed nursing care. CONCLUSIONS: As an alternative strategy to reduce missed nursing care in situations with insufficient nursing staffing, organizational support should precede nurse-physician and nurse-nurse collaboration. In particular, improving nurse-physician collaboration shows promise in mitigating missed nursing care.

[Prevalence of hyperhomocysteinemia and related factors in a community-based health examination survey: a cross-sectional study].

BACKGROUND: Many previous studies have shown that elevated homocysteine in the serum is a well known risk factor for cardiovascular disease and this is associated with other risk factors for cardiovascular disease, but any Korean data on this is limited. OBJECTIVES: This study aimed to calculate the prevalence of hyperhomocysteinemia and to analyze the relation between elevated homocysteine and the lifestyle factors of Korean adults. METHODS: We conducted a cross-sectional survey that included 650 men and 743 women (age range, 20 to 79 years) who were residents of Gwangju City in Gyeonggi-do. These subjects participated in the health interview and examination survey from November to December 2005. The total homocysteine, total cholesterol, HDL-cholesterol, LDL-cholesterol, and triglyceride in the serum were measured. All the participants had their body composition measured such as height and weight, and we obtained health-related behavioral information through the self-entry questionnaire. RESULTS: Very right-handed skewed distributions of homocysteine were shown in men and women. The prevalence of hyperhomocysteinemia was 22.6% in men and 13.7% in women in Gwangju city. On the multiple logistic regression analysis, hyperhomocysteinemia was associated with age (OR=1.02, 95% CI=1.01-1.04), male gender (OR=1.60, 95% CI=1.02-2.52), severe general physical activity (OR=0.32, 95% CI=0.15-0.69) and nutrient consumption (OR=0.49, 95% CI=0.31-0.76). CONCLUSIONS: There is a great prevalence of hyperhomocysteinemia in adults of Gwangju City, Korea and it was associated with both genetic factors and lifestyle risk factors. This study can suggest that comprehensive lifestyle modification is needed in order to diminish the prevalence of hyperhomocysteinemia and to prevent CVD.
