Abstract Objectives and background Social demands of the school-year and summer environment may affect children’s sleep patterns and circadian rhythms during these periods. The current study examined differences in children’s sleep and circadian-related behaviors during the school-year and summer and explored the association between sleep and circadian parameters and change in body mass index (BMI) during these time periods. Methods This was a prospective observational study with 119 children ages 5 to 8 years with three sequential BMI assessments: early school-year (fall), late school-year (spring), and beginning of the following school-year in Houston, Texas, USA. Sleep midpoint, sleep duration, variability of sleep midpoint, physical activity, and light exposure were estimated using wrist-worn accelerometry during the school-year (fall) and summer. To examine the effect of sleep parameters, physical activity level, and light exposure on change in BMI, growth curve modeling was conducted controlling for age, race, sex, and chronotype. Results Children’s sleep midpoint shifted later by an average of 1.5 h during summer compared to the school-year. After controlling for covariates, later sleep midpoints predicted larger increases in BMI during summer, (γ = .0004, p = .03), but not during the school-year. Sleep duration, sleep midpoint variability, physical activity levels, and sedentary behavior were not associated with change in BMI during the school-year or summer. Females tended to increase their BMI at a faster rate during summer compared to males, γ = .06, p = .049. Greater amounts of outdoor light exposure (γ = −.01, p = .02) predicted smaller increases in school-year BMI. Conclusions Obesity prevention interventions may need to target different behaviors depending on whether children are in or out of school. Promotion of outdoor time during the school-year and earlier sleep times during the summer may be effective obesity prevention strategies during these respective times.

Postoperative Changes

Background In last few decades, several tools have been developed to measure physical function objectively; however, their use has not been well established in clinical practice. Objective This study aims to describe the preoperative physical function and to assess and compare 6-month postoperative changes in the physical function of patients undergoing treatment for aortic stenosis with either surgical aortic valve replacement (SAVR) or transcatheter aortic valve replacement (TAVR). The study also aims to evaluate the feasibility of wearable devices in assessing physical function in such patients. Methods This is a prospective observational study. The enrollment will be conducted 1 month before patients’ SAVR/TAVR. Patients will be provided with the wearable device at baseline (activity tracker device, Garmin vívoactive 3). They will be trained in the use of the device, and they will be requested to wear it on the wrist of their preferred hand until 12 months after SAVR/TAVR. After baseline assessment, they will undergo 4 follow-up assessments at 1, 3, 6, and 12 months after SAVR/TAVR. At baseline and each follow-up, they will undergo a set of standard and validated tests to assess physical function, health-related quality of life, and sleep quality. Results The ethics committee of Vicenza in Veneto Region in Italy approved the study (Protocol No. 943; January 4, 2019). As of October 2020, the enrollment of participants is ongoing. Conclusions The use of the wearable devices for real-time monitoring of physical activity of patients undergoing aortic valve replacement is a promising opportunity for improving the clinical management and consequently, the health outcomes of such patients.

Objectives We aimed to assess associations between depressive symptoms, lifestyle, and somatic symptoms during the COVID-19 pandemic. Design A prospective, observational study using a self-designed questionnaire. Setting Three general practitioners’ (GP) offices in rural Germany. Participants 271 adult patients without manifest cardiovascular or pulmonary disease with (n = 82) and without (n = 189) hypertension reporting to our GP offices. Main outcome measures The reported increase of depressive symptoms (loneliness, sleeplessness, joylessness, listlessness) prior to the first documented case in Germany on 27.01.2020 (t0) as opposed to patients’ health perception during the Corona pandemic (t1) was the primary outcome measure. The secondary outcome measures were changes in physical activity (PA), dyspnea and angina in the two groups. Results Out of 271 patients (50.8 ± 16.8 years, 55.1% females), 1.5% were tested positive for COVID-19. Overall, listlessness (8.5%, p = 0.001), sleeplessness (5.2%, p = 0.001) and joylessness (4.2%, p = 0.003) were increased. Dyspnea significantly increased (9.2%, p < 0.001) and employment status worsened (6.5%, p < 0.001). There were significant associations between the increase of depressive symptoms, weight increase (p = 0.017), and reduction in physical activity (p = 0.046). However, after adjusting for age, hypertensive patients did not show more depressive symptoms (p = 0.704), dyspnea (p = 0.063) or angina (p = 0.432), nor was there any difference in PA (p = 0.906) compared to healthy individuals. Conclusions We demonstrate an association between the deterioration of depressive symptoms, weight gain, and reduced physical activity during COVID-19, both in hypertensives and healthy controls. Hypertension is no driver of symptom deterioration during the pandemic. The trial was registered in the German Clinical Trials Registry (DRKS00022157).
