Nomogram for predicting changes in cognitive function in community dwelling older adults with mild cognitive impairment based on Korea Longitudinal Study of Ageing Panel Data: a retrospective study: Hyuk Joon Kim, Hye Young Kim; J Korean Acad Nurs 2025;55(1):50-63. Published online February 7, 2025; DOI: https://doi.org/10.4040/jkan.24059

Abstract PDF ePub: Purpose
This study aimed to identify factors associated with normal cognitive reversion and progression to dementia in older adults with mild cognitive impairment (MCI) residing in the community and to develop a nomogram.
Methods
This longitudinal study used secondary data from the Korea Longitudinal Study of Ageing Panel Data (2006–2018). The study included 1,262 participants aged 60 or older, with initial Mini-Mental State Examination scores ranging from 18 to 23. Data were analyzed using the Rao-Scott chi-square test, panel binary logistic regression, and receiver operating characteristic (ROC) curve in Stata ver. 17.0 (Stata Corp.).
Results
The rate of reversion from MCI to normal cognition was 37.0% after 2 years and 32.9% after 12 years. The rate of progression to dementia was 18.0% after 2 years and 30.2% after 12 years. In the nomogram for reversion to normal cognition, the most significant influences were grip strength, depression, number of meetings, age, and regular exercise, with an area under the ROC curve (AUC) of .66. In contrast, in the nomogram for progression to dementia, the most significant influences were age, grip strength, instrumental activities of daily living, number of social meetings attended, depression, and regular exercise, with an AUC of .69.
Conclusion
These nomograms can serve as an effective intervention tool for preventing dementia in the field of community health care since they can serve as a visual technique for presenting information on risk to individuals with MCI.

A Longitudinal Study of the Reciprocal Relationship between Depression and Income among Korean Older Men and Women: Lee, Jeong , Jeon, Gyeong-Suk; J Korean Acad Nurs 2022;52(4):451-463. Published online August 31, 2022; DOI: https://doi.org/10.4040/jkan.22052

Abstract PDF: Purpose
This study examined the reciprocal relationships between depression and income, and gender differences in these relationships among older adults in South Korea.
Methods
Using 2015 to 2019 of the Korea Welfare Panel Study (KoWePS), we studied 6,070 older adults (2,394 men and 3,676 women) aged 60 years over in 2015. The generalized estimating equation was employed to explore the effect of an individual income on depression and the reverse causal link-that of depression on income.
Results
The study found the reciprocal relationships between income and depression. Income has a significant impact on depression. Higher-income was linked to decreased risks of the Center for Epidemiologic Studies Depression (CES-D) scores among older adults (B = - 0.121, p < 0.001). Estimates of the reverse causal link show that higher CES-D scores were also linked to income reduction among Korean older adults (B = - 0.007, p < 0.001). In addition, we also observed gender differences in the impact of income on depression but not in the reverse causal link. Income has more detrimental to psychological consequence for older men (B = - 0.108, p < 0.001) than older women (B = - 0.057, p < 0.001).
Conclusion
The finding implies that both psychological and social protection policies for the elderly are needed in view of gender perspective.

Factors Influencing Re-Employment of Newly Graduated Nurses: Longitudinal Study: Oh, Yun Kyung , Kim, Eun-Young; J Korean Acad Nurs 2021;51(2):162-172. Published online April 30, 2021; DOI: https://doi.org/10.4040/jkan.20158

Abstract PDF

Purpose
The purpose of this study was to identify factors influencing the re-employment of newly graduated nurses.
Methods
A longitudinal design was employed. The participants in this online survey study were 138 newly graduated nurses who had left their first jobs. Data were collected from June 2019 to January 2020 and analyzed using descriptive statistics, chi-square tests, t-tests, Cox’s proportional hazards models with the IBM SPSS ver. 26.0 for Windows program.
Results
About 76.1% of the participants were re-employed within one year of leaving their first jobs and the average period until re-employment was about 14 weeks. Cox’s proportional hazards models revealed that factors affecting re-employment among newly graduated nurses were social support (hazard ratio [HR] = 1.39, 95% confidence interval [CI] = 1.01~1.91; p = .042), job search efficacy (HR = 1.33, 95% CI = 1.01~1.77;p = .047), and extrinsic outcome expectation (HR = 1.39, 95% CI = 1.08~1.79; p = .010).
Conclusion
Social support, job search efficacy, and extrinsic outcome expectation can play a significant role in the re-employment of newly graduated nurses. It is necessary to establish strategies to enhance their social support, job search efficacy, and extrinsic outcome expectation in order to increase the re-employment of newly graduated nurses.

The Longitudinal Relationships between Depression and Smoking in Hardcore Smokers Using Autoregressive Cross-Lagged Modeling: Jeong Won Han, Hanna Lee; J Korean Acad Nurs 2019;49(1):69-79. Published online January 15, 2019; DOI: https://doi.org/10.4040/jkan.2019.49.1.69

Abstract PDF

Abstract Purpose

This study aimed to identify the directionality of the causal relationship and interaction between depression and amount of smoking over time in hardcore smokers using longitudinal descriptive analysis.

Methods

Secondary data from the Korean Welfare Panel Study were analyzed using autoregressive cross-lagged modeling. Participants included 342 hardcore smokers who participated in the 8th to 11th waves of the panel study.

Results

Analyses revealed that change(s) in depression levels according to time had a significant positive relationship with the total amount of smoking per day (β=.29, β=.19, β=.17, p<.001), while change(s) in total amount of smoking per day according to time had a significant positive relationship with depression (β=.43, β=.50, β=.38, p<.001). Analysis of the cross-lagged effect between depression and total amount of smoking per day showed that depression at one time point had a significantly positive relationship with the total amount of smoking per day at the next time point (β=.14, β=.13, β=.13, p=.021), and that the total amount of smoking per day at one time point had a significant positive relationship with depression at the next time point (β=.04, β=.04, β=.03, p=.044).

Conclusion

The findings in the present study confirmed a cross-interaction between depression and total amount of smoking per day in hardcore smokers. The present findings could be used to develop appropriate smoking-related interventions.
