PURPOSE: To examine effects of a postnatal care program on self-efficacy, self-management, and glycemic control in women with gestational diabetes mellitus (GDM). METHODS: A non-equivalent control group non-synchronized quasi-experimental design was used. Sixty-two women with GDM were enrolled and assigned to either an experimental group (n=30) or a control group (n=32). The experimental group received an intervention which was postnatal care program for women with GDM. The postnatal care program for GDM included an individual education with leaflet and mobile web-based video with three times of telephone counseling. Effects of the intervention were measured with self-efficacy, self-management questionnaire, and a 75 g oral glucose tolerance test (75g OGTT). Statistical significance was examined using independent t-test and χ2-test. RESULTS: Although there was no significant difference in 75g OGTT (χ2=.11, p=.748) or self-management (t=−1.28, p=.206), there was a statistically significant increase in self-efficacy (t=−2.02, p=.048) in the experimental group compared to that in the control group. CONCLUSION: A postnatal care program is needed for women with GDM to improve their self-efficacy. Further studies are warranted to improve self-management and glycemic control through tailored education for GDM postpartum women.

BACKGROUND: The objective of the current study was to determine whether there was an association between urinary albumin excretion and cardiovascular disease (CVD) risk by estimating the Framingham Risk Score (FRS) in postmenopausal women without diabetes. METHODS: This study was based on data from the Korea National Health and Nutrition Examination Survey, which was conducted by the Korean Ministry of Health and Welfare in 2011 to 2013. Data on 2,316 postmenopausal women from a total of 24,594 participants was included in the analysis. RESULTS: The mean FRS was significantly different in each of the urinary albumin to creatinine ratio (UACR) subgroups, and it increased with UACR. The FRS was 12.69±0.12 in the optimal group, 14.30±0.19 in the intermediate normal group, 14.62±0.26 in the high normal group, and 15.86±0.36 in the microalbuminuria group. After fully adjusting for potential confounding factors, high normal levels and microalbuminuria were significantly associated with the highest tertile of FRS ([odds ratio (OR), 1.642; 95% confidence interval (CI), 1.124 to 2.400] and [OR, 3.385; 95% CI, 2.088 to 5.488], respectively) compared with the optimal subgroup. High normal levels and microalbuminuria were also significantly associated with a ≥10% 10-year risk of CVD ([OR, 1.853; 95% CI, 1.122 to 3.060] and [OR, 2.831; 95% CI, 1.327 to 6.037], respectively) after adjusting for potential confounding covariates. CONCLUSION: Urinary albumin excretion reflects CVD risk in postmenopausal women without diabetes, and high normal levels and microalbuminuria were independently associated with a higher risk of CVD.

Objectives: The study aim was to analyze smoking knowledge and smoking cessation intentions according to the stage of change in smoking cessation behavior among smokers in their 20s. This program was implemented to prepare smoking cessation educational content in order to increase the success rate of smoking cessation. Methods: The analysis included 99 smokers in their 20s who lived in Seoul and Gyeonggi; the study period was February 14-16, 2024. After explaining the study purpose and obtaining consent for participation in the study, an online Google Forms survey was conducted. Results: Smoking cessation intention and smoking knowledge according to the smoking cessa-tion behavior change stage were significantly different depending on the presence of smokers and whether they attempted smoking cessation in the pre-contemplation period (P<0.05). In addition, the intention to quit smoking significantly increased in the pre-contemplation, contemplation, and preparation periods in the smoking cessation behavior change stage (P<0.001). Conclusions By operating a smoking cessation intervention program for smokers in their 20s, pro-viding correct smoking knowledge and finding ways to increase smoking cessation intention, smok-ers’ behavior can change and they can form a quitting habit. Therefore, we can expect that even middle-aged or older people can quit smoking.

Background: Although the consumption of vitamin beverages has increased because of the recent interest in health and beauty, guidelines addressing appropriate consumption habits are lacking. Thus, the aim of this study was to investigate the erosive potential of several vitamin beverages and to propose guidelines for the appropriate intake of these drinks. Methods: Five vitamin beverages were selected after a pre-investigation of the current beverage market. Coca-Cola and mineral water were selected as the control beverages. The pH of the beverages was measured with a calibrated pH meter, and the titratable acidity (TA) was determined by using 1 M sodium hydroxide to reach pH 5.5 (TA5.5) and 7.0 (TA7.0). The screening method suggested by the International Organization for Standardization was used to measure pH variation (pH) by using an under-saturated hydroxyapatite solution to determine the difference between the initial and final pH of the screening solution. All measurements were performed in triplicate. Results: All vitamin beverages tested in this study exhibited a low pH (2.53∼2.99), similar to Coca-Cola, which is known to be a highly acidic beverage. The highest TA5.5 and TA7.0 values of the vitamin beverages were 7.03 ml and 8.81 ml, respectively. The largest change in pH determined by using the screening solution was found in Bacchus D (pH 1.44±0.05). The mean pH of the vitamin beverages was 1.12±0.29, which was higher than that of Coca-Cola (positive control, pH 0.58±0.05). Conclusion Vitamin beverages exhibited an erosive potential capable of damaging enamel surfaces. Therefore, the frequency of vitamin beverage intake should be limited, and individuals consuming these drinks should try to restore normal oral pH as quickly as possible.

PURPOSE: This study aimed to confirm the mediating effect of job involvement in the relationship between grit and turnover intention among nurses working at university hospitals. METHODS: Participants included 437 nurses from university hospitals located in C city, Gyeongnam. Data were collected from January 8 to 19, 2018, using self-report questionnaires. Data were analyzed using the t-test, analysis of variance, Scheffe's test, Pearson's correlation coefficient, and multiple regression, with the SPSS/22.0 program. A mediation analysis was performed according to the Baron and Kenny, and bootstrapping methods. RESULTS: There were significant relationships between grit and job involvement (r=.40, p<.001), grit and turnover intention (r=−.29, p<.001), and turnover intention and job involvement (r=−.52, p<.001). Job involvement showed partial mediating effects in the relationship between grit and turnover intention. CONCLUSION: Grit increased job involvement and lowered turnover intention. Therefore, to reduce nurses' turnover intention, it is necessary to develop a program and strategies to increase their grit.

PURPOSE: In this study, we compared the risk of cardiovascular complications between diabetic retinopathy (DR) groups based on the Framingham Risk Score. METHODS: Subjects 40 years of age or older were enrolled in the present study from September 2008 to September 2009. Five scales were used to evaluate the severity of DR for the most severely affected eye in each patient: no DR, mild nonproliferative DR (NPDR), moderate NPDR, severe NPDR and proliferative DR (PDR). The first group included no DR patients and the second group included mild NPDR patients. The third group included moderate NPDR, severe NPDR and PDR patients. The Framingham Risk Score was analyzed among the groups to determine whether a difference in score existed. RESULTS: DR was found in 126 subjects. The first group included 403 subjects, the second group 22 subjects and the third group 104 subjects. The average Framingham Risk Score that appeared with increasing severity of DR was 10.89 ± 7.98 in the first group, 12.25 ± 10.84 in the second group and 13.25 ± 10.66 in the third group. The average difference between the first and third groups was statistically significant (p = 0.014). CONCLUSIONS: In our study, the Framingham Risk Score increased significantly with more severe DR (p = 0.042). Our results are useful when considering the easily accessible identification of DR and that cardiovascular disease is one of the main causes of death worldwide. However, confirming the exact causal relationship based on our results is difficult because the study design was cross-sectional and additional studies are necessary.
