Abstract
OBJECTIVES
The purpose of this study was to compare moderate-to-vigorous physical activity (MVPA) with walking in terms of associations with metabolic syndrome components in Korean older adults.
METHODS
Data on 1,388 older adults (age ≥65 years) from the Korea National Health and Nutrition Examination Survey 2018 were analyzed in this study. MVPA time and walking time per week were used as physical activity variables and blood pressure, waist circumference, glucose, high-density lipoprotein cholesterol, and triglyceride levels were analyzed as metabolic syndrome components. Partial correlations, analysis of covariance, and multinomial logistic regression were used for statistical analysis after adjusting for age, sex, smoking, and alcohol consumption.
RESULTS
High-density lipoprotein cholesterol levels were significantly higher in the low MVPA/high walking and high MVPA/ high walking groups than in the low MVPA/low walking group. Triglyceride levels were significantly lower in the high MVPA/ high walking group than in the low MVPA/low walking and low MVPA/high walking groups. Engaging in <150 min/wk of MVPA increased the likelihood of abnormal blood pressure and metabolic syndrome by 1.81 times and 1.89 times, respectively, compared to ≥150 min/wk of MVPA. Engaging in <180 min/wk of walking raised the likelihood of having abnormal highdensity lipoprotein levels by 1.32 times compared to ≥180 min/wk of walking.
CONCLUSIONS
Not only MVPA but also walking was significantly associated with metabolic syndrome components in Korean older adults. Considering older adults’ preferences and exercise barriers, walking should be considered as an essential component of physical activity guidelines to prevent chronic diseases in older adults.
Summary
Korean summary
현재까지 저강도 신체활동 (걷기)은 중고강도 신체활동에 비해 상대적으로 그 중요성이 간과되어 왔다. 하지만 본 연구는 저강도 신체활동도 중고강도 신체활동 못지 않게 노인들에게서 대사증후군을 예방할 수 있는 중요한 역할을 할 수 있음을 보여준다. 게다가 노인들의 신체적 제약, 부상의 위험, 운동 선호도 등을 감안하면 걷기와 같은 저강도 신체활동은 노인들의 건강유지를 위한 신체활동 권고사항의 필수요소로 고려되어야 함을 제안한다.

Abstract
OBJECTIVES
This study investigated physical activity (PA) participation based on demographic, physical, and psychological variables in Korean adults.
METHODS
Participants were divided into four groups (combined, aerobic only, resistance only, and neither) based on meeting the PA guidelines using moderate and vigorous PA time and resistance exercise frequency from the Korea National Health and Nutrition Examination Survey 2017. The association between meeting the PA guidelines and demographic, medical, fitness, lifestyle, and psychological variables were analyzed using complex samples crosstabs and a general linear model.
RESULTS
Of the 5,820 Korean adults, 66.0% did not meet any of the guidelines. Among demographic factors, sex, age, marital status, income, education level, occupation, and employment status were associated with meeting the PA guidelines. Chronic disease prevalence, weight, waist circumference, body mass index, diastolic blood pressure, glucose, high-density lipoprotein and triglyceride levels, hand-grip strength, resting heart rate, and family history of chronic disease in the medical and fitness variables; frequency of drinking and eating breakfast, total calorie, water, protein, and fat intake in the lifestyle variables; and perceived stress, depression, suicidal thoughts, and quality of life in the psychological variables were associated with meeting PA guidelines.
CONCLUSIONS
Most Korean adults participate in insufficient PA. Moreover, individuals who are socially underprivileged, have low-income or poor physical and mental health conditions participated in relatively less PA. Our findings suggest that government and individual efforts are required to increase PA and resolve health inequality in Korean adults.
Summary
Korean summary
2017년 국민건강영양조사 자료를 분석한 결과, 한국 성인들의 신체활동 실천율은 매우 낮았으며, 특히, 사회적 약자나 저소득층, 신체적, 정신적 건강 위험요인이 높은 사람들에게 더 낮게 나타났다. 신체활동은 건강증진을 위한 가장 경제적이며 효율적인 방법으로써, 신체활동 참여를 늘리고 건강불평등을 해소하기 위한 정부, 의료기관, 교육기관은 물론 국민 개개인의 신체활동에 대한 인식개선과 적극적인 노력이 필요하다.
