노인의 신체활동 및 수면시간과 건강 관련 삶의 질과의 연관성

국문 초록 (Abstract)

본 연구에서는 제 8기 1차년도 2019년에 실시된 국민건강영양조사를 이용하여
우리나라 노인의 신체활동 수준과 수면시간으로 건강 관련 삶의 질의 연관성 유무
를 검증하는 것을 주요 목적으로 하였다.
이를 위해 2019년 국민건강영양조사에 참여한 만 65세 이상 노인 1,690명(남자
723명, 여자 967명)을 대상으로 인구사회학적 요인, 건강형태 요인, 신체활동 수준을
알아보았다. 노인을 대상으로 도출해낸 기준을 활용하여 신체활동 수준을 파악하기
위하여 비활동(sedentary), 불충분(Insufficient), 충분(sufficient)으로 집단을 세분화한
다음 총 신체활동량을 MET 값으로 구하였다. 적정 수면시간을 파악하기 위하여 수
면시간을 부족군, 적정군, 과다군 세 집단으로 분류하고 주중, 주말 수면시간을 평
균으로 하여 건강 관련 삶의 질과의 연관성을 분석하였다.
연구결과, 신체활동 수준은 건강 관련 삶의 질과 유의한 차이가 있는 것으로 나
타났으며(p<.001), 삶의 질 점수는 낮을수록 좋으며, 신체활동 수준이 낮을수록 건
강 관련 삶의 질 점수는 높게 나타났다. 총신체활동량과 건강 관련 삶의 질은 유의
한 차이가 있는 것으로 나타났으며(p<.001), 총신체활동량이 증가할수록 건강 관련
삶의 질 점수가 증가하는 것으로 나타났다. 또한, 독립적인 연관성 유무를 검증하기
위해 성별, 연령, 교욱수준, 소득수준, 결혼상태, 음주, 흡연, 건강상태 등 요인을 모
두 보정한 후에는 통계적으로 유지되지 않는 것으로 나타났다(p=.303). 수면시간과
건강 관련 삶의 질은 유의한 차이가 있는 것으로 나타났으며(p<.001), 집단 중 적정
군의 경우 건강 관련 삶의 질 점수가 가장 낮은 것으로 나타났으며, 과다군의 경우
건강 관련 삶의 질 점수가 가장 높게 나타났다. 이후 건강 관련 삶의 질의 독립예
측변인을 알아보기 위하여 성별, 연령, 교육수준, 소득수준, 결혼상태, 음주, 흡연, 건
강상태를 통계적으로 보정한 후에도 수면시간은 유의한 독립예측변인인 것으로 나
타났다.
본 연구의 결과를 종합하면, 노년기의 수면은 건강 관련 삶의 질과 연관성이 있
으며, 건강 관련 삶의 질을 높이기 위하여 신체활동을 수행하는 것과 수면시간이
중요하다는 사실을 시사하는 것으로 판단된다.

The main purpose of this study was to verify the relationship between
physical activity and sleep time and health related quality of life the in elderly
in Korea using the National Health and Nutrition Survey conducted in 2019 in
the 8th year.
To this end, 1,690 elderly people (723 males, 967 females) aged 65 or older
who participated in the 2019 National Health and Nutrition Examination Survey
were examined for demographic factors, health type factors, and physical
activity. In order to identify the level of physical activity using the criteria
derived for the elderly, the group was subdivided into sedentary, insufficient, and
sufficient, and then the total amount of physical activity was calculated as the
MET value. In order to identify the optimal sleep time, it was classified into
three groups: insufficient group, adequate group, and excessive group, and
analyzed the correlation with health-related quality of life by averaging the
average sleep time on weekdays and weekends.
As a result of the study, it was found that the level of physical activity had
a significant difference from health-related quality of life (p<.001), the lower the
quality of life score, the better, and the lower the level of physical activity, the
higher the health-related quality of life score. There was a significant difference
between total physical activity and health-related quality of life (p<.001), and as
- 52 -
total physical activity increased, health-related quality of life scores increased.
In addition, after adjusting all factors such as sex, age, education level, income
level, marital status, drinking, smoking, and health status to verify the presence
or absence of an explanatory variable, it was found that it was not statistically
maintained (p=.303). There was a significant difference in sleep time and
health-related quality of life (p<.001), and among the groups, the health-related
quality of life score was the lowest in the appropriate group, and the
health-related quality of life score was the highest in the excessive group.
Afterwards, sleep time was found to be a significant explanatory variable even
after statistically correcting sex, age, education level, income level, marital
status, drinking, smoking, and health status to identify independent predictors of
health-related quality of life.
the results of this study, Sleep in old age is correlated with health-related
quality of life, suggesting that performing physical activities and sleeping time
are important to improve health-related quality of life.
