Abstract
BackgroundSedentary behaviour (SB) is potentially an important target to improve cardiovascular health. This study 1) compared SB between cardiovascular disease (CVD) patients and age-matched controls, 2) identified characteristics associated with high SB levels, and 3) determined the impact of contemporary cardiac rehabilitation (CR) on SB. MethodsFor objective 1, we recruited 131 CVD patients and 117 controls. All participants were asked about their general characteristics and medical history. SB was assessed by an objective accelerometer (activPAL3 micro). For objective 2, 2584 CVD patients were asked to fill in a questionnaire about their general characteristics, lifestyle, medical history and their SB. For objective 3, 131 CVD patients were followed over time and measured, pre-, directly post- and 2 months post-CR. ResultsObjective 1. CVD patients spent 10.4 h/day (Q25 9.5; Q75 11.2) sedentary which was higher compared to healthy controls (9.4 h/day [Q25 8.4; Q75 10.29]). Objective 2. CVD patients being male, single or divorced, employed, physically inactive, reporting high alcohol consumption, living in an urban environment, having comorbidities and cardiac anxiety demonstrated a greater odds for large amounts of SB. Objective 3. The CR program significantly reduced sedentary time (−0.4 h/day [95%CI -0.7; −0.1]), which remained lower at 2-months post-CR (−0.3 h/day [95%CI -0.6; −0.03]). ConclusionsCVD patients had greater amounts of objectively measured sedentary time compared to healthy controls. Sedentarism was associated with personal- and lifestyle characteristics, and comorbidities. Participation in a contemporary CR program slightly reduced sedentary time, but tailored interventions are needed to target SB in CVD patients.
Highlights
A physically inactive lifestyle is increasingly common in the Western world [1] and is characterized by low levels of moderate-to-vigorous intensity physical activity (MVPA) and high levels of sedentary behaviour⁎ Corresponding author at: Dept. of Physiology (392), Radboud University Medical Center, P.O
We found that general characteristics and lifestyle-related characteristics were associated with total sedentary time of patients with CVD
We found that the reduction in sedentary time was mainly replaced by Light intensity physical activity (LIPA), whereas no changes in MVPA were found post-CR
Summary
A physically inactive lifestyle is increasingly common in the Western world [1] and is characterized by low levels of moderate-to-vigorous intensity physical activity (MVPA) and high levels of sedentary behaviour⁎ Corresponding author at: Dept. of Physiology (392), Radboud University Medical Center, P.O. High SB levels (9.7 ± 2.0 h/day) among acute coronary syndrome patients at 28 days post-discharge [16] It is unknown how these SB characteristics differ from age-matched healthy controls, and which patient- and disease-characteristics are associated with high SB levels. This study 1) compared SB between cardiovascular disease (CVD) patients and age-matched controls, 2) identified characteristics associated with high SB levels, and 3) determined the impact of contemporary cardiac rehabilitation (CR) on SB. For objective 2, 2584 CVD patients were asked to fill in a questionnaire about their general characteristics, lifestyle, medical history and their SB. Conclusions: CVD patients had greater amounts of objectively measured sedentary time compared to healthy controls. Participation in a contemporary CR program slightly reduced sedentary time, but tailored interventions are needed to target SB in CVD patients
