Physical Activity, Sedentary Behavior, and Sleep Quality in Adults with Primary Hypertension and Obesity before and after an Aerobic Exercise Program: EXERDIET-HTA Study.

ABSTRACT: BACKGROUND:The purposes of the study were to: analyze, by objective (accelerometry) and subjective (International Physical Activity Questionnaire, IPAQ) methodologies, the physical activity (PA) and sedentary behavior (SB) in healthy adults (HEALTHY, n = 30) and individuals with primary hypertension (HTN) and overweight/obesity (n = 218); assess the effects of an aerobic exercise intervention on physical activity (PA), sedentary behavior (SB), and sleep quality in the HTN group; and evaluate the relationship between objectively measured and subjectively reported PA and SB. METHODS:The measurements were performed before a 16-week exercise intervention period in both HEALTHY and HTN groups and after the intervention period only in the HTN group, randomized to attention control or exercise training (ExT) subgroups. RESULTS:The HEALTHY group showed more moderate-to-vigorous PA (p < 0.05) and better sleep quality (p < 0.05) than the HTN group, but no difference in SB. After the intervention, HTN participants' PA and SB, objectively measured by accelerometry, were unchanged, but increased PA and decreased SB (p < 0.05) were observed through IPAQ in ExT. The intervention was effective in improving sleep quality in HTN participants. CONCLUSIONS:The differences in moderate-to-vigorous PA and SB may be useful in defining the health profile of a population. The supervised aerobic exercise program was effective in increasing PA, reducing SB, and improving sleep quality in overweight/obese adults with HTN. Accelerometer-measured and self-reported data were not comparable, but complementary.

Project description:ObjectivesThis study reports on the feasibility of the SitLess with MS trial, an intervention targeting sedentary behavior in individuals with multiple sclerosis (MS).DesignSingle group, pre-post intervention design.SettingCommunity.ParticipantsParticipants (N=41) with mild to moderate disability from MS.InterventionThe intervention was 15 weeks, with a 7-week follow-up, and included 2 stages: SitLess and MoveMore. During the SitLess stage, participants were encouraged to break up prolonged sitting bouts over a 7-week period, whereas the MoveMore stage promoted increased steps per day and interrupting sitting over a 7-week period. The intervention was delivered through weekly one-on-one coaching sessions via telerehabilitation and an accompanying newsletter based on social-cognitive theory. Activity was monitored throughout the program using a Fitbit.Main outcome measuresProcess (eg, recruitment) and resource and management (eg, personnel requirements) metrics were assessed, along with efficacy outcomes (eg, effect). Progression criteria were set a priori and were related to safety, fatigue, satisfaction, and attrition. Sedentary behavior, measured using the ActivPal, was reported pre- and postintervention, as well as 7 weeks postintervention. Effect sizes (pre to post, pre to 7 weeks post) were calculated for the sedentary behavior outcomes (eg, time sitting, transitions from sitting to standing, number of long sitting bouts). Experiences with the intervention were explored through an online survey.ResultsForty-one participants enrolled, 39 of whom completed the intervention. All participants but 1 were satisfied with the experience. Pre-post intervention effect sizes for change in total sedentary time, number of transitions from sit to stand, and number of long (>30 min) sedentary bouts were 0.34, 0.02, and 0.39 respectively. All a priori progression criteria were met.ConclusionsThe SitLess with MS program, a novel intervention that emphasized and facilitated sitting less and moving more, was feasible and resulted in small changes in sedentary behavior in individuals with MS.

Project description:Background: Dystonia is a neurological movement disorder that presents as sustained or intermittent involuntary muscle contractions causing abnormal postures and movements. Knowledge of dystonia is mostly at the impairment level with minimal understanding of activity and participation limitations. Physical activity (PA) is an important aspect of neurological disease management, with wide-ranging benefits for overall health and quality of life. No studies have quantified PA and sedentary behavior (SB), nor explored barriers to being physically active in people with dystonia. Methods: Participants diagnosed with any form of dystonia completed a mixed-methods anonymous online survey on activity behaviors. The International Physical Activity Questionnaire (IPAQ) and Adult Sedentary Behavior Questionnaire (SBQ) assessed self-reported PA and SB. Barriers to exercise engagement were investigated according to the five-factor social-ecological framework and dystonia-specific questions regarding the impact of exercise on symptoms were included. Results: Two-hundred and sixty-three participants consented to the study (mean (SD) age = 55 (13) years, 76% Female). A large proportion of respondents (40%) reported living with cervical dystonia (CD). Overall, the median (IQR) time spent in walking, moderate, and vigorous activity was 60 (0-120), 120 (15-300), and 0 (0-13) min/day, respectively. SB time during weekdays was 285.0 (157.5-465.0) min/day and 345.0 (195.0-502.5) min/day on weekends. Fifty-five percent of participants were dissatisfied with their current level of PA and 75% reported dystonia had decreased their level of PA. Fifty-seven percent found their symptoms were worsened during exercise though the after-effects on symptoms varied. Fatigue, motor symptoms, pain, and poor balance were commonly cited limiting factors. Qualitative and quantitative data indicated difficulties with more vigorous intensity activity. The common barriers to engagement were personal and governmental factors, such as physical impairments, lack of funding and lack of trained exercise professionals. Conclusion: While more than half of respondents indicated they were not satisfied with their current level of PA, and exercise primarily worsened their dystonia symptoms, most participants were meeting the minimum guidelines. Future studies should incorporate robust objective methods of PA and SB measurement and explore the causal mechanisms underpinning exercise-induced aggravation of dystonic symptoms to further enhance life participation of people living with dystonia.
