Lifestyle segmentation of older Koreans: a longitudinal comparison of segments and life satisfaction

PurposeAging is a global phenomenon for many countries, and South Korea has become the fastest aging country in the world. The purpose of this study is to identify and validate a representative typology of older Koreans based on their lifestyle and value orientations. This study also makes a longitudinal comparison of these segments in two waves using similar survey data collected in 2009 and 2017 and examines any meaningful changes that occurred during the periods.Design/methodology/approachUsing survey data collected from 750 older adults living in four major cities in Korea, this study conducted factor and cluster analysis to identify lifestyle segmentation of elderly Koreans. Both descriptive and mean comparison analyses are followed to characterize the segments with relevant demographic and behavioral variables. In addition, this study makes a longitudinal comparison of these segments in two waves (2009 and 2017) and examines any meaningful changes that occurred during the periods.FindingsSix distinctive lifestyle segments of elderly Koreans are identified. The longitudinal comparison reveals some changes that occurred during the period. The level of importance of values and things to own has been declined during the period on most of the aspects, which can be interpreted that older Koreans become more realistic and practical. The level of life satisfaction between the two periods turned out to be similar. However, satisfaction in material comfort and health has been improved during the period, which means that the perception of their financial and physical aspects has been improved over the years.Originality/valueFirst, based on Tempest et al.’s three grey discontinuity framework (2002), the segmentation model provides comprehensive coverage of psychological transitions experienced by older people due to economic, physical and mental discontinuities with age. Second, this might be the first longitudinal study to examine the changes in segmentation over time in terms of the lifestyle of older adults. Practically, the findings of this study provide useful insights for policymakers in developing aging-related policies as well as for marketers who are interested or currently doing business in Korea or Asian consumer markets.

The Impacts of the Neighborhood Built Environment on Social Capital for Middle-Aged and Elderly Koreans

The purpose of this study was to investigate the relationship between the neighborhood built environment (NBE) aspects of age-friendly cities and communities (AFCCs) and social capital in the Korean context. We described and compared age differences when analyzing misfits of AFCC NBE and impacts on social capital. We collected the data (N = 1246) from two Korean communities; our multiple and binary logistic regression outcomes show that AFCC NBE aspects such as outdoor spaces, transportation, and housing are significant predictors of different subcategories of social capital. For the older group, the outdoor spaces misfit was significant for all three subcategories of social capital, but transportation and housing misfits were significant for the social trust and reciprocity index scores. For the middle-aged group, the outdoor spaces misfit was significant for social networking and participation, and a transportation misfit was significant for participation and social trust and reciprocity. Fewer misfits or better fits of outdoor spaces and transportation encouraged more networking, participation, social trust, and reciprocity. Dwelling type was important to predict social capital, especially for the older group. The present study confirmed the importance of AFCC NBE in predicting social capital and unique factors in the Korean context.

Physical Activity Amount and Cognitive Impairment in Korean Elderly Population

The relationship between physical activity amount and cognitive function in elderly Koreans has received little attention. This study therefore aimed to understand the independent and common link between cognitive function and physical activity levels among elderly Korean adults. This study recruited a total of 2746 elderly adults (1348 males and 1398 females). All participants were assessed for cognitive functioning using the Korean Dementia Screening Questionnaire Cognition (KDSQ-C). The computerized Korean version short form of the International Physical Activity Questionnaire (IPAQ) used in this study was entirely based on the long, self-administered, usual week-long IPAQ found in the IPAQ manual of operation. In the unadjusted model, elderly adults who met the recommended level of moderate-to-vigorous physical activity were more likely to have a sufficient level of cognitive function. Hemoglobin, creatinine, cholesterol (TC), triglycerides (TG), LDL-C, and HDL-C differed significantly between groups. A negative correlation was found between KDSQ-C score and the moderate-to-vigorous physical activity (MVPA) amount per week. Physical activity amount is associated with cognition function in Korean elderly adults. Increasing physical activity may improve hemoglobin and creatinine and be involved in improving serum lipid profiles in elderly adults. Thus, physical activity has been suggesting as a useful tool to reduce the risk of cognitive function associated with aging.
