A Multivariable Prediction Model for Mild Cognitive Impairment and Dementia: Algorithm Development and Validation.

Background: Mild cognitive impairment (MCI) poses significant challenges in early diagnosis and timely intervention. Underdiagnosis, coupled with the economic and social burden of dementia, necessitates more precise detection methods. Machine learning (ML) algorithms show promise in managing complex data for MCI and dementia prediction.

The relationship between grandparental childcare experience and relative handgrip strength among middle-aged and older adults.

Delayed marriage and childbirth often result in individuals becoming grandparents in middle and older age, coinciding with significant physical transitions. This study examines the relationship between the intensity of grandparental childcare, measured in terms of time-commitment over the last year, and relative handgrip strength among South Korea adults aged 45-84. Data from 3,742 participants with grandchildren were analyzed using the 2008-2010 waves of the Korean Longitudinal Study of Aging.

A comparative retrospective longitudinal study of arthritis risk and cognitive decline in older adults.

Arthritis often results in unmet healthcare needs for older adults with cognitive decline, who may struggle to communicate pain or recall symptoms. However, the risk factors for arthritis in this group remain underexplored. We addressed this gap by identifying and comparing arthritis risk factors among older adults with varying cognitive statuses.

Behavioral marker-based predictive modeling of functional status for older adults with subjective cognitive decline and mild cognitive impairment: Study protocol.

Objective: This study describes a research protocol for a behavioral marker-based predictive model that examines the functional status of older adults with subjective cognitive decline and mild cognitive impairment.

Methods: A total of 130 older adults aged ≥65 years with subjective cognitive decline or mild cognitive impairment will be recruited from the Dementia Relief Centers or the Community Service Centers. Data on behavioral and psychosocial markers (e.

Correlates of Mild Behavioral Impairment in Older Adults: Protocol for a Scoping Review.

Background: Understanding mild behavioral impairment, a relatively recent notion in neuropsychological studies, provides significant insights into early behavioral indicators of cognitive decline and predicts the onset of dementia in older adults. Although the importance of understanding mild behavioral impairment is acknowledged, comprehensive reviews of its correlates with older adults are limited.

Objective: This scoping review aims to identify the impact of mild behavioral impairment on health outcomes in older adults and the factors associated with mild behavioral impairment.

Gender differences in the association between transitions in depressive symptoms and oral health among older adults with chronic conditions.

Background: Oral health influences the quality of life of older adults. Further, depression is negatively associated with oral health. However, little is known about this relationship among older adults with chronic health conditions.

Factors influencing caregiver burden by dementia severity based on an online database from Seoul dementia management project in Korea.

Backgrounds: As the prevalence of dementia rises, caregiver burden also increases in South Korea, especially for informal family caregivers. This study aimed to analyze factors affecting caregiver burden by the severity of dementia based on data of patients in Seoul.

Methods: A total of 12,292 individuals aged ≥65 years enrolled in the Seoul Dementia Management Project from 2010 to 2016 in an online database were selected.

The determinants of caregiver use and its costs for elderly inpatients in Korea: a study applying Andersen's behavioral model of health care utilization and replacement cost method.

Objectives: The average annual healthcare expenditure among elderly patients in Korea is increasing rapidly in indirect healthcare sectors, requiring an understanding of factors related to the use of both formal and informal caregivers. This study analyzed the characteristics of caregiver use and caregiving costs among elderly patients hospitalized due to acute illness or exacerbation of chronic diseases.

Methods: A total of 819 study participants were selected from the 2017 Korea Health Panel Study Data.

Development of Korean Head forms for Respirator Performance Testing.

Background: Protection from yellow dust and particulate matter is ensured by the use of respirators among the Korean citizens and workers. However, the manikins used to test the performance of the same were manufactured considering western facial specifications owing to which they do not represent Korean facial characteristics.

Methods: Analysis of the data from the 6th 3D anthropometric survey of Koreans (Size Korea; 2010-2013) of 4,583 people aged 7 to 69 years was performed to obtain their facial dimensions.
