Abstract
OBJECTIVESThis 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.METHODSFrom 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.RESULTSInverse 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.CONCLUSIONSOur findings indicate the necessity to account for various types of physical activity to improve the assessment and prevention of obesity.
Highlights
Evidence has shown that physical activity (PA) is a major determinant of obesity
Participants were asked to identify the number of times they participated in vigorous-intensity physical activity during leisure time (VPAL), vigorous-intensity physical activity at work (VPAW), and moderate-intensity physical activity (MPA) during the past year
High household income significantly reduced the risk of obesity among women who engaged in low-intensity PA (Table 3). This is the first study to evaluate the associations of different patterns of PA and obesity among older adults in rural areas
Summary
Accelerating engagement in PA plays a crucial significant role in fighting the obesity epidemic, espe-. Recommended efforts have been implemented as interventions, the prevalence of obesity has yet to significantly decrease in a single country worldwide [2]. It is predicted to dramatically increase along with the rising global burden of obesity-related diseases in upcoming years [3]. More concerted efforts are needed to create PA interventions and to improve obesity prevention strategies globally. Numerous studies have investigated the role of PA in obesity to suggest appropriate interventions for preventing weight gain and maintaining a healthy weight. It is necessary to identify how various patterns of PA affect obesity to obtain a more comprehensive understanding
