Abstract
This study aimed to investigate the relationships between different types of physical activity (PA) and metabolic syndrome (MetS). In this cross-sectional study, 3,296 Taiwanese workers were enrolled. A self-reported questionnaire was used to assess nutritional health behavior and PA levels related to occupation, leisure time, and commuting. Anthropometric measures, blood pressure and biochemical determinations of the blood were also obtained. Multiple logistic regression was used to evaluate the adjusted odds ratios (ORs) and 95% confidence intervals (CI) of MetS and its components associated with different types of PA. The prevalence of MetS was 16.6% in workers. Compared with a low level of leisure-time PA, a high level of leisure-time PA showed a significantly lower risk of high triglycerides (OR 0.73, 95% CI 0.61–0.87) and MetS (OR 0.76, 95% CI 0.62–0.95). Compared with a low level of occupational PA, a high level of occupational PA represented a significantly lower risk of both abdominal adiposity (OR 0.64, 95% CI 0.49–0.84) and high triglycerides (OR 0.71, 95% CI 0.55–0.90). However, commuting PA levels were not significantly associated with MetS and its components. In conclusion, occupational PA as well as leisure-time PA could be important for the prevention of MetS.
Highlights
Metabolic syndrome (MetS) is a clustering of at least three of the five following metabolic disturbances: abdominal obesity, elevated blood pressure (BP), elevated fasting blood glucose (FBG), high triglycerides (TG), and low high-density lipoprotein cholesterol (HDL-C)[1]
Possible mechanisms associated with regular leisure-time physical activity (PA) that may reduce the risk of metabolic syndrome (MetS) or its components include the following: (1) improving body composition through decreased abdominal adiposity[14,15]; (2) ameliorating lipid and lipoprotein profiles through lipid oxidation and lowering TG levels, raising HDL-C levels and reducing the low-density lipoprotein cholesterol (LDL-C)-to-HDL-C ratio[16,17,18]; (3) ameliorating glucose homeostasis through contracting muscles to increase the uptake of blood
This study suggests that a high level of leisure-time PA is related to a lower risk of MetS
Summary
Metabolic syndrome (MetS) is a clustering of at least three of the five following metabolic disturbances: abdominal obesity, elevated blood pressure (BP), elevated fasting blood glucose (FBG), high triglycerides (TG), and low high-density lipoprotein cholesterol (HDL-C)[1]. With respect to chronic diseases, studies showed that moderate to high levels of leisure-time PA were associated with reducing the risk of type 2 diabetes[27], heart failure[28], and total and CVD mortality[29]. Moderate or high levels of occupational PA were related to reducing the risk of coronary heart disease[30], heart failure[28], type 2 diabetes[27], and total and CVD mortality[29]. Discrepancies in the potential benefits of different types and levels of PA for reducing the risk of MetS or its components among workers remain and require further study so that proven strategies can be defined and programs can be implemented. The objective of this study was to determine the relationships between different types and levels of PA and MetS and its components in workers
