한국 성인에서 흡연 상태에 따른 악력: 제7기 국민건강영양조사 2016–2017년 자료 이용 = Hand Grip Strength according to the Smoking Status in Korean Adults: The 7th Korea National Health and Nutrition Examination Survey 2016–2017

다국어 초록 (Multilingual Abstract)

Background: Smoking is a well-known risk factor for respiratory diseases, cardiovascular diseases, and many types of cancers, but there is littleinformation about the effects of smoking on muscle strength. Hand grip strength (HGS) is a simple way to measure muscle power. We compared themean HGS according to smoking status and smoking level in Korean male and female smokers.
Methods: We obtained data from the Korea National Health and Nutrition Examination Survey VII and included adults aged 20–79 years. We identifiedfactors that affect HGS and after adjusting for these factors, we compared the mean HGS of smokers, ex-smokers, and nonsmokers. We alsocompared the mean HGS of smokers according to the smoking level. ANOVA and ANCOVA analyses were performed to compare the mean HGS. Inaddition, we examined the relationship between smoking, and mean main HGS, which is the mean HGS of the dominant hand.
Results: A total of 9,848 people were analyzed after excluding those with uncertain smoking status and those who did not respond to the studyvariables. After adjusting for all cofactors, the mean HGS and the mean main HGS were higher in smokers and ex-smokers than in both male andfemale nonsmokers with no previous history of smoking. In smokers, the amount of smoking did not affect the mean HGS or mean main HGS.
Conclusion: Smokers and ex-smokers have higher mean HGS and mean main HGS than nonsmokers, and the amount of smoking does not affect themean HGS and mean main HGS in smokers.

연구배경: 흡연이 호흡기계, 심혈관계 질환 및 각종 암 발병의 위험인자라는 사실은 잘 알려져 있으나 흡연이 골격근과 근력에 미치는 영향에 대해서는 명확하게 알려진 바가 없다. 악력은 근력을 측정하는 가장 간단한 방법이다. 이 연구는 우리나라 성인 남녀에서 서로다른 흡연 상태에 따라, 흡연자의 경우 흡연량에 따라 평균 악력에차이가 있는지 알아보고자 하였다.
방법: 국민건강영양조사 제7기 1차년도(2016), 2차년도(2017) 자료를이용하였고 20–79세의 성인을 대상으로 조사하였으며 남녀를 구분하여 분석하였다. 악력에 영향을 미치는 요인들을 확인하였고 이러한 요인들을 보정한 뒤 흡연자, 과거 흡연자, 비흡연자에 따라 양손의 평균 악력을 비교하고 흡연자 내에서 흡연량에 따른 평균 악력에차이를 알아보았다. 흡연 상태에 따른 평균 악력과 흡연자에서 흡연량 사분위 집단에 따른 평균 악력을 확인하기 위해 분산분석 및 공분산분석을 실시하였다. 추가로 주로 사용하는 손의 평균 악력과흡연과의 관계도 알아보았다.
결과: 국민건강영양조사에 참여한 20–79세 성인 12,178명 중 흡연상태가 불확실한 사람과 연구변수에 미조사 혹은 무응답 항목이있는 사람들을 제외한 뒤 9,848명을 대상으로 분석을 하였다. 악력에 영향을 미치는 요인을 알아본 결과 남녀 모두에서 나이가 적을수록, BMI가 높을수록, 신체활동량이 많을수록, 교육수준이 높을수록, 가구소득이 많을수록, 주관적 건강상태가 좋을수록 악력이높았다. 모든 변수들을 보정한 결과 남녀 모두에서 흡연자와 과거흡연자가 평생 흡연을 한 적 없는 비흡연자보다 평균 악력과 주로사용하는 손의 평균 악력이 높았다. 흡연자에서 흡연량은 평균 악력과 주로 사용하는 손의 평균 악력에 영향을 미치지 않았다.
결론: 흡연자와 과거 흡연자가 비흡연자에 비해 평균 악력과 주로사용하는 손의 평균 악력이 높으며 흡연자에서 흡연량은 평균 악력과 주로 사용하는 손의 평균 악력에 영향을 미치지 않는다.
