Background.Physical activity guidelines for adults only recognize the health benefits of accumulating bouted moderate-to-vigorous physical activity (MVPA), or MVPA occurring over at least 10 consecutive minutes. There is a lack of evidence supporting the health benefits of other patterns and intensities of activity including sporadic MVPA (i.e., MVPA occurring in periods of fewer than 10 consecutive minutes) and light intensity physical activity (LIPA). The objective of this study was to examine the health benefits associated with physical activity that does not meet the physical activity guidelines criteria for bouted MVPA. Specifically, we examined the association between sporadic MVPA and bouted and sporadic LIPA with the metabolic syndrome.Methods.We studied a representative cross-sectional sample of 1,974 adults aged 20 years and older from the 2003–2006 US National Health and Nutrition Examination Survey. Physical activity was measured over 7 days using Actigraph AM-7164 accelerometers. Each minute over the 7-day measurement period was classified as being of a sedentary, light, or moderate-to-vigorous intensity. A 10 min threshold differentiated bouted activity from sporadic activity. Average minutes/day of sporadic LIPA, sporadic MVPA, bouted LIPA, bouted MVPA, and embedded MVPA (MVPA occurring within bouts of primarily LIPA) were calculated. Metabolic syndrome status was determined using established criteria. Associations were examined using logistic regression and controlled for relevant covariates.Results.For every 30 min/day of physical activity, the odds ratio (95% confidence interval) of the metabolic syndrome was reduced by 4% (1–7%) for bouted LIPA, 64% (51–71%) for bouted MVPA, and 57% (45–67%) for embedded MVPA. Sporadic LIPA was not independently associated with the metabolic syndrome. We could not examine the association between sporadic MVPA and the metabolic syndrome because participants accumulated such a marginal amount of this type of activity (i.e., median = 2 min/day, only 11% of participants accumulated ≥5 min/day).Conclusion.The intensity of non-bouted activity is important, as embedded MVPA had a stronger association with the metabolic syndrome than sporadic LIPA and a comparable association to bouted MVPA.

OBJECTIVES: 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.METHODS: 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.RESULTS: 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.CONCLUSIONS: Our findings indicate the necessity to account for various types of physical activity to improve the assessment and prevention of obesity.

Background: Physical activity is associated with improved quality of life. Patients with an implantable cardioverter defibrillator (ICD) face unique clinical and psychological challenges. Factors such as fear of ICD shock may negatively impact on physical activity, while a sense of protection gained from the ICD may instil confidence to be active. Aim: We aimed to examine the impact of an ICD on physical activity levels and factors associated with amount of activity. Methods: Two cross-sectional studies were conducted. Accelerometer data (seven-day) was collected in March–November 2015 for 63 consecutively recruited hypertrophic cardiomyopathy patients, with or without an ICD, aged ⩾18 years. A survey study was conducted in July–August 2016 of 155 individuals aged ⩾18 years with an inherited heart disease and an ICD in situ. Results: Based on the International Physical Activity Questionnaire, mean leisure time physical activity was 239 ± 300 min/week with 51% meeting physical activity guidelines. Accelerometry showed that mean moderate–vigorous physical activity was the same for patients with and without an ICD (254 ± 139 min/week versus 300 ± 150 min/week, p=0.23). Nearly half of survey participants ( n=73) said their device made them more confident to exercise. Being anxious about ICD shocks was the only factor associated with not meeting physical activity guidelines. Conclusions: Patients with inherited heart disease adjust differently to their ICD device, and for many it has no impact on physical activity. Discussion regarding the appropriate level of physical activity and potential barriers will ensure best possible outcomes in this unique patient group.

OBJECTIVE: To assess participation in physical activity and knowledge of general nutrition and current public health messages about the health benefits of physical activity in university dance students, and to investigate differences between first-year and later-year students and between students in dance and dance performance course groups. METHODS: This cross-sectional study recruited 67 participants from dance undergraduate degrees in a university in Australia. Nutrition knowledge was assessed using the General Nutrition Knowledge Questionnaire. Physical activity participation and awareness of its benefits were assessed using the Active Australia Survey. RESULTS: Results indicate low nutrition knowledge among dance students, with 47% and 52% of responses correct in dance and dance performance students, respectively. Nutrition knowledge did not vary between students in first or later years. Self-reported participation in moderate and vigorous physical activity varied substantially and met or exceeded recommendations based upon duration and frequency for 98% of participants. However, awareness of physical activity messages varied, with dance students more likely to disagree about the level of activity needed for health benefits. CONCLUSIONS: Dance students report varying levels of physical activity that usually met or exceeded recommendations; however, knowledge of general nutrition and physical activity benefits was low. Improved knowledge could contribute to changes in behavior that improve health status in this population.

This study investigated (i) the prevalence of the metabolic syndrome (MetS) in people with a long-standing spinal cord injury (SCI); (ii) whether personal or lesion characteristics are determinants of the MetS; and (iii) the association with physical activity or peak aerobic capacity on the MetS. In a cross-sectional study, persons with SCI (N = 223; time since injury of ≥10 years) were tested. The individual components of the MetS were assessed together with the physical activity measured by the Physical Activity Scale for Individuals with Physical Disabilities (PASIPD), while peak aerobic capacity was tested during a graded wheelchair exercise test on a treadmill. Thirty-nine percent of the participants had MetS. In a multivariate logistic regression analyses and after performing a backward regression analysis, only age and education were significant determinants of the MetS. A 10-year increase in age leads to a 1.5 times more chance to have the MetS. Furthermore, people with a low education will multiply the relative risk of MetS compared with people with high education by almost 2. With and without correcting for confounders, no significant relationship was found between PASIPD or peak aerobic capacity and the MetS. It can be concluded that the prevalence of the MetS is high (39%) in people with a long-standing SCI but is comparable to the general Dutch population. Older people and those with a lower education level are most at risk for the MetS. Physical activity and peak aerobic fitness were not related to the MetS in this group with a long-standing SCI.

The relationship between physical activity levels, salivary cortisol, and the metabolic syndrome (MetSyn) score was examined. Twenty-three girls (8.4 ± 0.9 years) had a fasting blood draw, waist circumference and blood pressure measured, and wore an ActiGraph accelerometer for 5 days. Saliva samples were collected to measure cortisol levels. Previously established cut points estimated the minutes spent in moderate, vigorous, and moderate-to-vigorous physical activity. A continuous MetSyn score was created from blood pressure, waist circumference, high-density-lipoprotein (HDL), triglyceride, and glucose values. Correlation analyses examined associations between physical activity, cortisol, the MetSyn score, and its related components. Regression analysis examined the relationship between cortisol, the MetSyn score, and its related components adjusting for physical activity, percent body fat, and sexual maturity. Vigorous physical activity was positively related with 30 min post waking cortisol values. The MetSyn score was not related with cortisol values after controlling for confounders. In contrast, HDL was negatively related with 30 min post waking cortisol. Triglyceride was positively related with 30 min post waking cortisol and area under the curve. The MetSyn score and many of its components were not related to cortisol salivary levels even after adjusting for physical activity, body fat percentage, and sexual maturity.

Background: Regular moderate-to-vigorous-intensity physical activity results in health benefits in people with diabetes. No study has observed the moderate-to-vigorous-intensity physical activity typically performed by people with diabetes-related foot ulcers (DFU) in their everyday free-living environments. We observed the bouts, and accumulated time, spent doing moderate-to-vigorous-intensity physical activity in cases with DFU compared with diabetes-related peripheral neuropathy (DPN) and diabetes (DM) controls over a one-week period. Methods: This was a secondary analysis of a cross-sectional case-control study. Participants wore a multisensor device for >5 days (>22 hours per day). Primary outcomes included the number, duration (minutes) and intensity (metabolic equivalent tasks [METs]) of bouts of moderate-to-vigorous-intensity physical activity (defined as at least >3 METs for >10 consecutive minutes). Secondary outcomes included the total accumulated times spent doing moderate-to-vigorous-intensity physical activity (>3 METs) and doing sedentary-intensity activity (<1.5 METs). DFU subgroups with minor amputations and nonremovable offloading devices were also analyzed. Results: Overall, 15 DM, 23 DPN, and 27 DFU participants were included. All groups recorded similar low median daily numbers (0.33, 0.29, 0.25 numbers, respectively), duration (15, 17, 14 minutes), and intensity of daily bouts of moderate-to-vigorous-intensity physical activity (4.1, 4.3, 3.9 METs) (all, P > .1). Median accumulated daily time spent doing moderate-to-vigorous-intensity physical activity was also similar (40, 37, 36 minutes; P > .8). Those with DFU had more mean accumulated daily time spent doing sedentary-intensity activity (796 minutes) compared to DPN (720 minutes; P < .05), but not compared to DM (728 minutes; P < .08). DFU subgroups with minor amputations had more median accumulated daily time spent doing moderate-to-vigorous-intensity physical activity (66, 28 minutes; P < .05) and less mean time doing sedentary-intensity activity (745, 837; P < .05) than those without amputations. Conclusions: People with DFU performed similar low numbers of daily bouts of moderate-to-vigorous-intensity physical activity to controls, but spend more time doing sedentary-intensity activities. Interventions that gradually increase the moderate-to-vigorous-intensity physical activity in people with DFU should be investigated.

Background: When promoting physical activity practice, it is important to consider the plausible environmental determinants that may affect this practice. We aimed to explore the impact of objectively measured Public Open Spaces (POS) on objectively measured and self-reported physical activity and the influence of weather on this association, in a Mediterranean sample of senior adults with overweight or obesity and the metabolic syndrome. Method: Cross-sectional analyses based on 218 PREDIMED-Plus trial participants aged 55 to 75 years, from Palma de Mallorca (Spain). Indicators of access to POS were assessed in a 1.0 km sausage network walkable buffer around each participant’s residence address using geographic information systems. Mean daily minutes of self-reported leisure-time brisk walking, and accelerometer objectively measured moderate-to-vigorous physical activity in bouts of at least 10 min (OM-MVPA) were measured. To investigate the association between access to POS and physical activity, generalized additive models with Gaussian link function were used. Results: Better access to POS was not statistically significantly associated with self-reported leisure-time brisk walking. A positive significant association was only observed between the distance of healthy routes contained or intersected by buffer and OM-MVPA. This association was only evident on non-rainy days. Conclusions: In this elderly population living in a Mediterranean city, only healthy routes contained or intersected by a 1 km sausage network walkable buffer influenced the accelerometer objectively measured moderate-to-vigorous physical activity in bouts of at least 10 min and rainy conditions during the accelerometer period appeared to be an important factor related to active ageing.

Abstract This study investigated whether low levels of physical activity in different domains is associated with risk factors for the occurrence of metabolic syndrome or metabolic syndrome itself. Habitual physical activity level was assessed among 963 participants, aged 50 years old or more, using Baecke’s questionnaire. Risk factors for metabolic syndrome followed the recommendations of “The IDF Consensus Worldwide Definition of the Metabolic Syndrome”. All the participants were users of the Brazilian Public Healthcare System. The prevalence of metabolic syndrome was 30.9%. Participants with lower levels of physical activity in leisure-time had higher chances of occurrence of diabetes mellitus, hypercholesterolemia and metabolic syndrome. Occurrence of arterial hypertension was associated with lower levels of sports activities. It was found high rates of risk indicators for the occurrence of metabolic syndrome, as well as for diseases alone as hypertension, diabetes mellitus, hypercholesterolemia, and obesity. Lower involvement in physical activity in different domains increases the prevalence of risk factors for metabolic syndrome.
