은퇴기 임금근로자의 고용상태 변화와 좌식생활 시간 변화의 관계

This study assesses the change in sedentary time (ST) during daily life after the change of employment status (ES) of salary workers nearing retirement. The results of this study intend to help prepare measures to support health care during this period. The relationship between ES and ST changes was analyzed by applying the chi-squared test and multiple logistic regression analysis. Data analysis was achieved using SPSS (ver. 25.0). The study enrolled 1,268 salary workers aged over 50 years who participated in the Korea Health Panel Survey (2014 to 2016), a secondary data source, and had no missing values. The average ST of the near-retirement salary workers was 5.35 hours in 2014 and 5.21 hours in 2016. Results of this study showed that changes showing increased duration of ST were significantly higher in the unemployed than the currently employed (OR= 1.76, 95% CI= 1.02-3.02) and in subjects with changed ES compared to the sustained ES (OR= 1.48, 95% CI = 1.10-2.00). Considering the age group, ST was significantly higher in the fifties (OR= 1.57, 95% CI= 1.04-2.35) but not in the sixties. It was observed that the changes in ES were affecting the changes in ST. Since increased ST might be one of the risk factors leading to all-cause mortality and morbidity, it is necessary to prepare a customized health management strategy that reflects the ES changes during the near-retirement period.
