Background:To date, no longitudinal studies have examined the influence of sedentary behavior on metabolic syndrome development while accounting for cardiorespiratory fitness.Purpose and Methods:This prospective study examined the relationship between sedentary behavior and incident metabolic syndrome while considering the effects of physical activity and cardiorespiratory fitness on the association among 930 men enrolled in the Aerobics Center Longitudinal Study.Results:A total of 124 men developed metabolic syndrome during 8974 person-years of exposure. After adjusting for covariates, men with middle and high sedentary behavior had 65% and 76% higher risks of developing metabolic syndrome, respectively, than men with low sedentary behavior (linear trend P = .011). This association remained significant after additional adjustment for activity status and cardiorespiratory fitness. Cardiorespiratory fitness and physical activity were also inversely associated with metabolic syndrome, even after adjustment for sedentary behavior.Conclusions:The findings highlight the importance of reducing sedentary behavior, increasing physical activity, and improving cardiorespiratory fitness for preventing metabolic syndrome.

ABSTRACT Introduction: Metabolic Syndrome (MetS) has been associated with sedentary behavior, low levels of physical activity and of cardiorespiratory fitness. However, in adolescents the results are conflicting. Objective: To measure the association between sedentary behavior, physical activity, cardiorespiratory fitness and MetS in a representative sample of adolescents. Methods: The sample consisted of 1,035 adolescents (565 girls and 470 boys) between 12 and 20 years of age. Sedentary behavior was treated through recreational screen time, while information equivalent to physical activity was considered through the Physical Activity Questionnaire for Adolescents. The maximal oxygen uptake (VO2max), estimated through PACER performance, was used as an indicator of cardiorespiratory fitness. MetS was identified using the criteria of the International Diabetes Federation. Results: Adolescents of both sexes identified with MetS had significantly longer recreational screen time and lower VO2max than their unidentified MetS peers. Scores equivalent to the level of physical activity undertaken by adolescents identified and not identified with MetS were statistically similar. Probabilistically, adolescents with high recreational screen time and low VO2max had, respectively, 79% [OR = 1.79; 95% CI 1.10 – 2.82] and 95% [OR = 1.95; 95% CI 1.20 – 3.09] greater odds of being identified with MetS. Conclusion: The findings indicate consistent and significant associations between longer recreational screen time, low VO2max values and high prevalence of MetS, which suggests specific interventions designed to help minimize cardiometabolic risk exposure from a very early age.

Purpose: To describe physical activity habits, sedentary behavior, and cardiorespiratory fitness levels among alcohol abstainers, hazardous and non-hazardous drinkers. Design: Cross-sectional study with data collected between 2017-19. Setting: Sweden. Subjects: Adults aged 18-65 years (n = 47,559; 59.4% male). Measures: During a routine health assessment, participants answered validated single-item questions regarding: habitual physical activity, structured exercise, and the percentage of time spent sedentary during leisure-time (past 30 days), and completed a 6-minute cycle ergometer test (V02max) to determine cardiorespiratory fitness (CRF). Participants were categorized as alcohol abstainers, non-hazardous drinkers or hazardous drinkers (low/high) based on the Alcohol Use Disorders Identification Test (AUDIT-C) cut-points for men and women. Analysis: Logistic regression models stratified by sex and age. Results: Compared to non-hazardous drinkers, the heaviest drinkers were less physically active (males: OR = 1.38, CI = 1.13-1.67, p = .001; females: OR = 1.41, CI = 1.01-1.97, p = .040) and more sedentary during leisure time (males: OR = 1.94, CI = 1.62-2.32, p = .000; females: OR = 1.62, CI = 1.21-2.16, p = .001). Apart from young females, the heaviest drinkers also did less structured exercise than non-hazardous drinkers (males: OR = 1.22, CI = 1.15-1.51, p = .000; females: OR = 1.43, CI = 1.15-1.78, p = .001). The strongest associations were seen among adults aged 40-65 years (shown here). High-hazardous drinking was associated with low CRF among older males only (OR = 1.19, CI = 1.00-1.41). Conclusion: Middle-aged adults with AUDIT-C scores of ≥6 (women) and ≥7 (men) were less physically active and more sedentary during leisure time and may be appropriate targets for physical activity interventions.
