Abstract 4113188: Increased Physical Activity Intensity Associated with Reduced Risk of Atrial Fibrillation among Older Adults in South Korea: A Retrospective Cohort Study

Introduction: Physical activity (PA) may be associated with a lower risk of atrial fibrillation (AF), but this relationship remains controversial. In particular, further research is needed on the association between changes in PA intensity and AF risk among older adults. Hypothesis: We hypothesized that an increase in PA intensity would be associated with a reduced risk of AF among older adults aged 65 years and older in South Korea. Aim: This cohort study aimed to evaluate the association between changes in metabolic equivalent tasks (METs)-min/week and the risk of AF in the elderly using a nationally representative database. Methods: We conducted a retrospective cohort study using the Korea National Health Insurance Service (KNHIS) database. This cohort included 1,726,697 individuals aged 65 years and older without a history of cardiovascular disease diagnosis who underwent two consecutive health screening examinations from 2009 to 2012. PA was defined as MET-min/week derived from two consecutive health examinations during 2009-2010 (1st period) and 2011-2012 (2nd period), respectively. The primary outcome was an AF diagnosis during the follow-up period from 2013 to 2021. We estimated the sub-distribution hazard ratio (sHR) and 95% confidence interval (CI) for the association of changes in PA intensity with AF using Fine-Gray sub-distribution hazard models after adjustment for covariates. Results: This study included 1,726,697 participants (mean age 71.08; 46.78% male). An increase in PA intensity was associated with a reduced risk of AF (P for trend<0.001). Compared to persisting in physical inactivity, a change in PA intensity from physically inactive to ≥1000 MET–min/week was associated with a lower risk of AF (sHR, 0.83, 95% CI, 0.81-0.85). In contrast, a change in PA intensity from ≥1000 MET–min/week to being physically inactive was associated with a higher risk of AF (sHR, 1.30, 95% CI, 1.27-1.33) as compared to persistence in ≥1000 MET–min/week of PA intensity. Conclusions: An increase in MET-min/week may be associated with a reduced risk of AF among adults aged 65 years and older. Therefore, interventions encouraging PA should be recommended to maximize the health benefits of AF prevention in the elderly.

Barefoot Walking (Earthing) Craze and Policy Support Among Community-Dwelling Older Adults in South Korea: A Grounded Theory Analysis

Barefoot walking is currently a craze in South Korean communities. In particular, the elderly are participating in barefoot walking (earthing) to improve their physical and mental health due to their increasing desire for a healthy life. The purpose of this study was to analyze causes, processes, and consequences of the barefoot walking craze among the elderly in Korean society. The research method used was the grounded theory method. Thirty-five elderly people participating in barefoot walking were selected as participants. Data were analyzed according to open coding, axial coding, and selective coding proposed by Strauss and Corbin. First, an open coding phase yielded 61 concepts, 18 subcategories, and 7 categories through continuous questioning and comparative analysis. Second, in the axial coding stage, causal, contextual, and mediating conditions, action/interaction strategies, and consequences were presented, centering on the phenomenon. Causal conditions and contextual conditions contributing to the phenomenon of barefoot walking were identified as “motivation to participate” and “barefoot walking environment,” respectively. “Participating in barefoot walking” was identified as a phenomenon in the axial coding paradigm. The intervening condition was analyzed as “information about barefoot walking.” The action/interaction strategy was analyzed as “spreading the value of barefoot walking.” In the axial coding paradigm, consequences that emerged through the action/interaction strategy were “restoring physical and mental health” and “community spread and nuisance.” Third, in the selective coding stage, “barefoot walking as a daily routine” was derived as the core category, and the narrative outline was presented. To create a sustainable barefoot walking environment in Korea, it is necessary to have a healthy civic consciousness that coexists and harmonizes with nature.

The development of the self-other distinction in perceptions of social influence.

Prior research documents that adults in Western cultures perceive others as more susceptible to social influence than themselves (Pronin et al., 2007). Study 1 (N = 318) investigated the cultural generalizability of this asymmetric perception effect by examining young adults in South Korea, where conformity is relatively valued, and a comparison sample of young adults in the United States. The results documented that, counter to theoretical accounts emphasizing the centrality of motivated reasoning, the self-other distinction was just as strong in South Korea as it was in the United States. Study 2 (N = 102) examined the development of this tendency among 6- to 12-year-old South Korean children and showed that this asymmetry is first present at around age 9. These findings suggest that asymmetric perceptions of conformity are robust and emerge over the course of development. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Prevalence and Risk Factors of Self-Reported Sarcopenia and Its Association With Multimorbidity in Community-Dwelling Older Adults: A Cross-Sectional Study.

This cross-sectional study aimed to identify the impact of multimorbidity on self-reported sarcopenia and compare the differences in the prevalence and associated factors of sarcopenia in community-dwelling older adults with and without multimorbidity. We enrolled 876 community-dwelling older adults in South Korea. Multimorbidity was defined as the coexistence of two or more chronic diseases, and sarcopenia was evaluated using the Strength, Assistance in walking, Rising from a chair, Climbing stairs, and Falling Questionnaire. Binomial logistic regression analyses were performed. Our study revealed that the prevalence of sarcopenia was significantly higher (43.5%) in older adults with multimorbidity than in those without multimorbidity (20.8%). This finding underscores the significant impact of multimorbidity on sarcopenia. We also found that poor perceived health status was the strongest predictor of sarcopenia in older adults with multimorbidity, while oldest-old age (≥ 85 years) was the strongest predictor of sarcopenia in those without multimorbidity. Large prospective cohort studies using objective sarcopenia screening tools are needed to demonstrate the synergistic effects of multimorbidity and sarcopenia on health outcomes among community-dwelling older adults.

Factors Influencing Suicidal Ideation in Young and Middle-aged Adults in Korea: A Nationwide Study

Abstract Objectives This study aims to analyze various factors influencing suicidal ideation among young (19-39 years) and middle-aged (40-64 years) adults using nationwide longitudinal data in South Korea, which has the highest suicide rate among OECD countries for more than 20 years. Methods An analysis was conducted using the WAVE II data (2016-2017) from a nationwide longitudinal study on the mental health of suicide survivors (LoSS). The sample included 2,002 participants (1,290 young adults, 712 middle-aged adults) recruited through stratified proportional quota sampling. Multiple regression analysis was performed to identify factors influencing suicidal ideation in each age group. Results In young adults, being female, having a high school education or lower, being unmarried/divorced/widowed, and having higher levels of depression were positively associated with suicidal ideation. Higher levels of social support and better subjective physical health were negatively associated with suicidal ideation. In middle-aged adults, being unemployed, living alone, drinking alcohol more than once a week, and having higher levels of depression were positively associated with suicidal ideation, while higher levels of social support were negatively associated with suicidal ideation. Conclusions Factors influencing suicidal ideation differ between young and middle-aged adults. Age-specific suicide prevention strategies considering these factors are needed to promote social health and stability in South Korea. Key messages • Different factors influence suicidal ideation in young and middle-aged adults in South Korea. • Age-specific suicide prevention strategies are necessary to effectively address suicidal ideation and promote social health and stability in South Korea.

Prevalence, Risk Factors, and Impact of Long COVID Among Adults in South Korea.

This study aimed to identify the prevalence, risk factors, and impact of long COVID in a community-based representative sample of patients with COVID-19 aged 19-64 years. A total of 975 participants completed online or telephone surveys at 1 and 3 months post-diagnosis, covering persistent symptoms, daily activity limitations, vaccination status, and underlying diseases. Long COVID, as defined by the WHO criteria, had a prevalence of 19.7-24.9% in females and 12.7% in males. Logistic regression revealed that the odds of having long COVID symptoms were higher among females compared to males (OR, 2.43; 95% CI, 1.53-3.87), and higher in those aged ≥ 30 years compared to those aged 19-29 years: 30-39 years (OR, 2.91; 95% CI, 1.59-5.33), 40-49 years (OR, 2.72; 95% CI, 1.51-4.89), and 50-64 years (OR, 1.96; 95% CI, 1.10-3.49). Additionally, patients with underlying diseases had higher odds of long COVID symptoms compared to those without underlying diseases (OR, 1.81; 95% CI, 1.24-2.64). Among those with long COVID, 54.2% experienced daily activity limitations, and 40.6% received treatment. Furthermore, lower income groups faced greater daily activity limitations but had similar treatment rates to higher income groups. These findings emphasize the need for interest in and the development of programs to support these low-income populations.

Objectives This study aims to analyze the trends of research on music and cultural arts education for middle-aged adults in South Korea and discuss future challenges. Methods To achieve the research objectives, the study conducted a literature search using key terms such as ‘middle-aged’, ‘adults’, ‘music and cultural arts education’, ‘music’, ‘choir’, and ‘performance’. Following a four-step selection process, 20 relevant papers were analyzed based on established analytical categories. Results The research has increased since 2011-2015, with master's theses comprising the highest proportion. The primary subjects of these studies were middle-aged women aged 40-60, focusing mainly on the analysis of effects and impacts. Personal domain topics were frequently addressed, with quantitative research being the predominant method. Among the various music activities, singing was the most commonly studied. Conclusions The findings highlight the need for further research targeting middle-aged men, the development of programs and content exploration, as well as literature reviews and qualitative research approaches. Future studies in these areas could contribute to the design and advancement of music and cultural arts education for middle-aged adults, both academically and practically.

Diagnosis and Treatment of latent tuberculosis infection in adults in South Korea

Latent tuberculosis infection (LTBI) is characterized by immune responses to Mycobacterium tuberculosis antigens without clinical symptoms or evidence of active tuberculosis. Effective LTBI management is crucial for tuberculosis elimination, requiring accurate diagnosis and treatment. In South Korea, LTBI guidelines have been updated periodically, with the latest in 2024. This review discusses the recent changes in the Korean guideline for the diagnosis and treatment of LTBI in adults.

Spatiotemporal variability of the association between greenspace exposure and depression in older adults in South Korea

Abstract Background A number of studies based on young to middle aged adult and child samples have found that exposure to greenspace and bluespace can have a positive impact on mental health and well-being. However, there is limited research among older adults and the extant studies have provided mixed results. The present study was designed to examine how the association between these forms of exposure and depressive symptoms among older adults varies as a function of different spatially and temporally resolved exposure metrics. Methods The sample consisted of 617 individuals (46.19% female) aged ≥ 60 years of age. Depressive symptoms were measured using the 10-item Center for Epidemiological Studies Depression Scale (CES-D). Individuals’ greenspace exposure was quantified using spatially and temporally resolved metrics, including monthly and annual averaged satellite-derived normalized difference vegetation index (NDVI) across multiple buffer distances (250 m to 2,000 m) centered at participants’ home address. We also quantified exposure to blue-greenspace from a highly detailed land use and land cover dataset. A multivariable logistic regression model assessed the association between greenspace and blue-greenspace exposure and depressive symptoms, adjusting for age, sex, income, education, marital status, current smoking, alcohol status, medical conditions, temperature, crime rate, population density, and per capita park area. Results We found a significant association between exposures to greenspace and blue-greenspace and depressive symptoms (CES-D cutoff ≥ 4) among older adults. After adjusting for confounding variables, the odds of depressive symptoms were significantly decreased by an IQR increment in residential exposure to greenspace [odds ratio (OR) = 0.67; 95% confidence interval (95% CI), 0.49 ~ 0.91] and blue-greenspace (OR = 0.59; 95% CI, 0.41 ~ 0.84) measured nearby their home address (i.e., as close as 250 m). When stratified by household income level, the association was only significant among low-income individuals. We also found temporal variation in the association between depressive symptoms and monthly NDVI-based greenspace exposure, in which the odds of depressive symptoms were the lowest for greenspace in cold months (i.e., January, February, and March). Conclusions Our findings suggest that neighborhood greenspace may serve as a protective factor against depression among older adults, but the benefits may depend on the spatial and temporal context. More investigation is needed to replicate our findings on the spatial and temporal variations of greenspace exposure metrics and their effects on depressive symptoms.

Analysis of the impact of digital literacy on life satisfaction (2019–2022) for older adults in South Korea: a national community-based panel study

This study analyzed the effects of digital literacy on life satisfaction in older adults aged 65 years and above in modern day Korea. It utilized raw data from the 2019–2022 Report on the Digital Divide, an annual survey conducted by the Korean Ministry of Science and Information and Communications Technology. A total of 4,216 participants were assessed from 2019–2022. Correlation between digital literacy and life satisfaction was analyzed using Pearson correlation analysis and polynomial linear regression analysis. Life satisfaction was significantly positively correlated with digital access, digital competency, and digital utilization in all the years. In 2019, participants’ life satisfaction score rose significantly by 0.15 with every one-point increase in digital competency. It further rose by 0.035 in 2020, 0.030 in 2021, and 0.116 in 2022. Digital literacy was consistently positively correlated with life satisfaction in each year from 2019–2022. Of the three main elements, digital competency had the strongest impact and digital information, income, and education level also significantly impacted life satisfaction. While digital competency improved steadily from 2019 to 2022, it remains below 50% for Korea’s older adult population. Further efforts are required to improve digital competency and subsequent life satisfaction among Korea’s older adult population.

Exploring social activity patterns among community-dwelling older adults in South Korea: a latent class analysis

BackgroundWith the trend of digitalization, social activities among the older population are becoming more diverse as they increasingly adopt technology-based alternatives. To gain a comprehensive understanding of social activities, this study aimed to identify the patterns of digital and in-person social activities among community-dwelling older adults in South Korea, examine the associated factors, and explore the difference in depressive symptoms by the identified latent social activity patterns.MethodsData were extracted from a nationwide survey conducted with 1,016 community-dwelling older adults (mean age 68.0 ± 6.5 years, 47.8% male). The main variables assessed were digital social activities (eight items), in-person social activities (six items), and depressive symptoms (20 items). Data were analyzed using latent class analysis, multinomial logistic regression, and multiple linear regression.ResultsWe identified four distinct social activity patterns: “minimal in both digital and in-person” (22.0%), “moderate in both digital and in-person” (46.7%), “moderate in digital & very high in in-person” (14.5%), and “high in both digital and in-person” (16.8%). Younger age, living in multi-generational households, and higher digital literacy were associated with a higher likelihood of being in the “moderate in both digital and in-person” than the “minimal in both digital and in-person” group. Younger age, male, living in multi-generational households, residing in metropolitan areas, no dependency on IADL items, doing daily physical exercise, and higher digital literacy were associated with a higher likelihood of being in the “moderate in digital & very high in in-person” than the “minimal in both digital and in-person” group. Younger age, living in multi-generational households, no dependency on IADL items, doing daily physical exercise, and higher digital literacy were associated with a higher likelihood of being in the “high in both digital and in-person” than the “minimal in both digital and in-person” group. Depressive symptoms were significantly higher in the group with minimal engagement in both digital and in-person activities, compared to other three groups.ConclusionsThis study highlights distinct patterns of social activities among Korean community-dwelling older adults. Since older adults with minimal social activity engagement can be more vulnerable to depressive symptoms, interventions that address modifiable attributes, such as supporting digital literacy and facilitating physical activity of older adults, could serve as potential strategies to enhance their social activity engagement and, consequently, their mental well-being.

The factors related to depressive symptoms in urban older adults in South Korea: a study based on the Seoul Aging Survey

PurposeThis study aims to comprehensively examine the determinants of depression among urban older adults in Seoul, utilizing the social-ecological model to address multifaceted influences.MethodsA comprehensive analysis was conducted using data from the 2022 Seoul Aging Survey, which surveyed 2,914 individuals aged 65 and above. A multiple logistic regression analysis was performed to identify factors contributing to depressive symptoms, including socio-demographic characteristics, health behaviors and status, research accessibility, social support, and environmental influences.ResultsThis study revealed that poor subjective health (OR = 1.47) and the presence of multiple chronic diseases (OR = 1.59) significantly increased the risk of depressive symptoms among urban older adults. From a social support standpoint, living alone was associated with a higher risk of depression (OR = 1.66), low food security (OR = 2.56), and low digital competency (OR = 2.70) were all significant predictors of depressive symptoms. Additionally, a lack of engagement with cultural facilities (OR = 2.15) was identified as a critical environmental factor contributing to depression.ConclusionsThe findings underscore the need for comprehensive policy and practical interventions aimed at preventing chronic disease, enhancing social support networks, improving digital literacy, ensuring food security, and expanding access to healthcare and cultural facilities. Such measures are crucial in mitigating depression among urban older adults, thereby enhancing their overall well-being and quality of life.

Incidence of hearing loss following COVID-19 among young adults in South Korea: a nationwide cohort study

The association of COVID-19 with hearing loss (HL) is unclear among young adults and needs to be investigated. This study was conducted to determine the association of COVID-19 with HL and sudden sensorineural hearing loss (SSNHL) in young adults. This nationwide population-based cohort study used data from the Korea Disease Control and Prevention Agency-COVID-19-National Health Insurance Service. The study population consisted of young adult citizens aged 20-39 years without a history of HL. All participants were followed up from July 1, 2022 until HL, death, or December 31, 2022. A positive diagnosis of SARS-CoV-2 infection was determined through laboratory testing employing real-time reverse transcription polymerase chain reaction assays using nasopharyngeal or oropharyngeal swabs. The primary and secondary outcomes were HL and SSNHL, respectively. Age, sex, household income, Charlson comorbidity index, COVID-19 vaccination, hypertension, diabetes, and dyslipidemia-adjusted subdistribution hazard ratios (aSHRs) and 95% confidence intervals (CIs) were evaluated using the Fine-Gray subdistribution hazard regression model, considering overall death as a competing event to compare the aSHRs between COVID-19 positive and negative groups. A total of 6,716,879 young adults were eligible for the analyses. During 40,260,757 person-months (PMs) of follow-up, 38,269 cases of HL and 5908 cases of SSNHL were identified. The risk of HL (incidence: 11.9 versus 3.4/10,000PMs; SHR, 3.51; 95% CI, 3.39-3.63; aSHR, 3.44; 95% CI, 3.33-3.56; P<0.0001) and SSNHL (incidence: 1.8 versus 0.5/10,000PMs; SHR, 3.58; 95% CI, 3.29-3.90; aSHR, 3.52; 95% CI, 3.23-3.83; P<0.0001) was higher in COVID-19 group as compared to no COVID-19 group. In the sensitivity analyses that evaluated HL and SSNHL risks after adopting multiple imputations, utilizing inverse probability of treatment weighting, limiting study population to the cohort with a health screening examination, the results were consistent to the primary analysis. Our findings suggest a heightened risk of HL and SSNHL following COVID-19 in young adults. Due to study limitations, including the lack of objective audiological data, issues with generalizability to other populations, and the retrospective design, careful interpretation is necessary. Further studies with objective audiological data and a longer follow-up period are warranted.

A Reciprocal Relationship between Formal and Informal Social Engagement and Handgrip Strength of Older Adults in South Korea

Introduction: The relationship between social engagement and handgrip strength has been underexplored. Further, no prior research examined a plausible reciprocal association between them. Methods: The study employed the seven waves of data (2006–2018) from the Korean Longitudinal Study of Aging (KLoSA) survey (7,927 respondents, mean age: 59 years old at wave 1 [71 years old at wave 7], women: 58%). It used ML-SEM, a cross-lagged panel model with fixed effects fitted by structural equation modeling with maximum likelihood estimation. In particular, the ML-SEM examined whether a reciprocal relationship existed between formal social engagement (number of association memberships and frequency of organizational activities)/informal social engagement (frequency of contact with familiar persons) and handgrip strength (the average of the four dynamometer measurements). Results: The empirical analyses identified a systematic reciprocal association between formal social engagement and handgrip strength. Specifically, formal social engagement was positively associated with handgrip strength over time (the number of association memberships standardized coefficient: 0.012*, the frequency of organizational activities standardized coefficient: 0.022***). Conversely, handgrip strength was positively related to the number of memberships (the handgrip strength standardized coefficient: 0.025*) and the frequency of organizational activities (the handgrip strength standardized coefficient: 0.042**). Conclusion: The study thus supports the social causation proposition that formal social engagement in and through diverse associations may be positively associated with handgrip strength. It also validates the health selection argument that handgrip strength may increase the likelihood of formal social engagement.

재가 노인의 돌봄 유형에 따른 우울 영향요인

Purpose : This study examines how different types of care－formal and informal－affect depressive symptoms in older adults at home. Methods : Using data from the 2020 National Survey on Older Adults in South Korea, which included responses from 498 elderly individuals receiving care, we conducted logistic regression analyses to identify factors influencing depressive symptoms based on the type of care received. Results : The analysis showed significant differences in depressive symptoms between those receiving formal and informal care. In the formal care group, a better subjective perception of health was associated with a lower likelihood of depressive symptoms (OR＝0.47, p＜.001), while an increase in chronic conditions (OR＝1.15, p＝.007) and higher dependency in instrumental daily activities (OR＝1.08, p＜.001) increased the risk of depressive symptoms. Conversely, improved cognitive function was linked to reduced depression risks (OR＝0.96, p＜.001). In the informal care group, similar trends were observed. Notably, family cohabitation significantly influenced depressive symptoms outcomes, highlighting the importance of family support in care dynamics. Access to necessary facilities and adequate care provision also emerged as critical factors in mitigating depressive symptoms risks across both care types. Conclusion : The study underscores the importance of tailored interventions that enhance care accessibility and adequacy, particularly in informal settings, to improve mental health outcomes among the elderly.

The Effects of Health and Unmet Dental Care Needs on the Health-Related Quality of Life in Korea Older Adults: A Nationwide Study

Background: The purpose of this cross-sectional study was to assess the relationship between oral health, unmet dental needs and health-related quality of life in South Korea older adults. Methods: The present study used raw data from the 2019~2020 Korea National Health and Nutrition Examination Survey, and analyzed 4956 participants aged over 65 yr. Hierarchical multiple regression analysis was used for associations between oral health, unmet dental needs, and HRQoL. Results: The EQ-5D index differed according to tooth pain, chewing difficulty, speaking problem, subjective oral health status, oral examination, and unmet dental care needs (P&lt;0.001). In the model 2, male, under 75 yr of age, high school graduate or higher, employed, living with a spouse, no stress, good subjective health status, no speaking problem, and no unmet dental care needs were associated with higher EQ-5D index (Adj R2 = 27.6%, P&lt;0.001). Conclusion: To improve the HRQoL of older adults in South Korea, oral health problems need to be minimized through oral disease prevention and oral health education programs.

Long-Term Care Insurance for Older Adults in Terms of Community Care in South Korea: Using the Framework Method.

This study aimed to analyze the long-term care insurance for older adults in South Korea in terms of community care. An analytical framework was designed for the study, focusing on comprehensiveness, adequacy, and integration. The findings suggest that Korean LTCI is significantly limited for the development of community care. First, in terms of comprehensiveness, the use of visiting nurses and the availability of short-stay services have been significantly reduced, and the supporting services for informal caregivers are at the beginning stage of their introduction. Second, in terms of adequacy, the quantity of benefits, such as three to four hours of care a day, are insufficient to meet older adults' substantial needs. Furthermore, the overall quality of home care services is low, particularly with regard to short-stay services and welfare equipment. Finally, in terms of integration, basic linkage of organizations has not been properly conducted in local areas, and there remains an absence of care managers in the LTCI system. To cope with these challenging issues, the following policy measures are suggested: the activation of rehabilitation services, the expansion of benefit quantities, the improvement of service quality, and the creation of organizational linkages through local authorities and long-term care centers.

Self-reported sensory impairment and social participation among Korean older adults: mediating roles of cognitive function and digital technology use

Objectives This study investigates the correlation between self-reported sensory impairment, cognitive function, digital technology use, and social participation among older adults in South Korea. Method Data from the 2020 National Survey of Older Koreans, comprising a nationally representative sample of 7849 individuals aged 65 years or older, were analyzed. A serial mediation analysis (Model = 6) was conducted using the PROCESS macro for SPSS. Results Following adjustment for covariates, cognitive function and digital technology use serially mediated the relationship between self-reported sensory impairment and social participation among older adults (B = −0.0020, SE = 0.0005, 95% confidence interval [CI] = [−0.0030, −0.0010]). Specifically, self-reported sensory impairment exhibited a negative correlation with cognitive function (B = −0.3277, SE = 0.0753, p < .001), which was positively associated with digital technology use (B = 0.0763, SE = 0.0056, p < .001), subsequently linking to enhanced social participation (B = 0.0784, SE = 0.0037, p < .001). Conclusion Through cross-sectional analysis, this study confirms that self-reported sensory impairment in older adults may precede cognitive decline, hindering digital technology use and reducing social participation. Early diagnosis and treatment are crucial in preventing cognitive decline, while age-friendly digital devices may alleviate cognitive burden and promote social engagement.

Effectiveness of Mobile-Based Progressive and Fixed Physical Activity on Depression, Stress, Anxiety, and Quality of Life Outcomes Among Adults in South Korea: Randomized Controlled Trial.

Depression acts as a significant obstacle to the overall well-being of individuals. Given the significant consequences, timely recognition and proactive steps to manage symptoms of depression become essential. Such actions not only reduce personal distress but also play a crucial role in reducing its far-reaching impact on society as a whole. In response to this concern, the objective of this study was to explore the use of mobile-based interventions as a possible remedy. More specifically, this study aimed to investigate the effectiveness of 2 types of physical activity (PA), progressive and fixed, within a mobile-based app on depression, perceived stress, anxiety, physical health, and psychological health, aiming to contribute to the optimization of mental health benefits. Participants (N=60; mean age 25.29, SD 6.10 years) were recruited using a combination of web-based and offline methods, and the study lasted for 8 weeks. The baseline and posttest questionnaires were administered to all participants. The participants were randomly assigned to 1 of the 3 groups: progressive group (n=20; performing mobile-based progressive PA), fixed group (n=20; performing mobile-based fixed intensity PA), and control group C (n=20). Data analysis involved comparing scores between the experimental and control groups using a one-way ANOVA, paired sample t tests (2-tailed), and repeated measures ANOVA with a 3 (group)×2 (time) design. The findings revealed significant improvements in mental health indicators among participants engaged in both fixed and progressive PA groups compared with the control group. However, the fixed PA group demonstrated more significant reductions in symptoms. Specifically, the progressive PA group showed significant reductions in depression (F1,36=6.941; P=.01; ηp2=0.16) and perceived stress (F1,36=5.47; P=.03; ηp2=0.13), while the fixed PA group exhibited significant reductions in depression (F1,37=5.36; P=.03; ηp2=0.12), perceived stress (F1,37=7.81; P=.008; ηp2=0.17), and general anxiety disorder (F1,37=5.45; P=.03; ηp2=0.13) compared with the control group. This study underscores the potential of mobile-based PA in improving mental health outcomes. The findings offer significant insights for mental health professionals and researchers aiming to optimize mental well-being through innovative mobile therapies.
