AbstractAbstract AbstractSummary PDF
This study was performed to identify the effect of physical activity at work on obesity and to analyze the contribution of socioeconomic factors and health behaviors to this association, which has been relatively little studied.
From the Korean National Cancer Center Community Cohort, a total of 5,587 adults (2,125 men; 3,462 women) aged more than 30 years living in rural areas were enrolled. Information on socio-demographic factors, health behaviors, and body mass index was gathered using face-to-face interviews and measurements of height and weight.
Inverse associations were identified between vigorous-intensity physical activity at work and obesity in both men and women, while no association was found between vigorous-intensity physical activity during leisure time and obesity. High household income was independently associated with a lower risk of obesity among those who had low levels of vigorous-intensity physical activity at work. Vigorous physical activity at work showed an inverse association with obesity in rural areas where heavy manual labor is common.
Our findings indicate the necessity to account for various types of physical activity to improve the assessment and prevention of obesity.
Korean summary
신체활동의 종류에 따라 비만에 미치는 영향의 차이가 있는지를 보기 위하여 육체 노동이 많은 농촌지역 성인을 대상으로 직무신체활동과 비만과의 관련성을 다른 잠재요인을 보정하여 분석하였다. 남녀 모두에서 고강도 직무신체활동과 비만과의 역연관성이 확인된 반면 여가신체활동과 비만과의 연관성은 확인되지 않았다. 가구소득이 높은 경우 직무신체활동의 강도가 낮은 경우에도 비만과 역연관성을 보였다. 향후 비만 예방 및 중재 전략 수립 시 대상집단의 특성을 고려하여 다양한 종류의 신체활동에 대한 평가가 고려되어야 할 것이다.
Key Message
Regarding the inverse association of physical activity at work and household income with obesity identified in the study, various type of physical activity including physical activity at work and characteristics of target population might be concerned for assessment and prevention of obesity.
