Abstract ‘Living Better’, a self-administered web-based intervention, designed to facilitate lifestyle changes, has already shown positive short and medium-term health benefits in patients with an obesity-hypertension phenotype. The objectives of this study were: (1) to examine the long-term (3-year) evolution of a group of hypertensive overweight or obese patients who had already followed the ‘Living Better’ program; (2) to analyse the effects of completing this program a second time (reintervention) during the COVID-19 pandemic. A quasi-experimental uncontrolled design was used. We recruited 29 individuals from the 105 who had participated in our first study. We assessed and compared their systolic and diastolic blood pressure (SBP and DBP, respectively), Body Mass Index (BMI), eating behavior, and physical activity levels (METs-min/week) at Time 0 (follow-up 12 months after the first intervention), Time 1 (before the reintervention), and Time 2 (post-reintervention). Our results showed significant improvements between Time 1 and Time 2 in terms of SBP [−4.7 (−8.7 to −0.7); P=.017], DBP [−3.5 (−6.2 to −0.8); P=.009], BMI [−0.7 (−1.0 to −0.4); P<.001], emotional eating [−2.8 (−5.1 to −0.5); P=.012], external eating [−1.1 (−2.1 to −0.1); P=.039], and physical activity levels (Time 1: 2308±2266; Time 2: 3203±3314; P=.030, Z=-2,17). Statistical analysis showed no significant differences in SPB, DBP, BMI, and eating behavior between Time 0 and Time 1 (P>.24). Implementation of the ‘Living Better’ program maintained some positive long-term (3-year) health benefits in patients with an obesity-hypertension phenotype. Moreover, a reintervention with this same program during the ongoing COVID-19 pandemic produced significant improvements in blood pressure, BMI, eating behavior, and physical activity levels beyond the 3-year follow-up.Trial Registration: ClinicalTrials.gov NCT04571450; https://clinicaltrials.gov/ct2/show/NCT04571450; First Posted: 01/10/2020.

Spaceflight can be associated with sleep loss and circadian misalignment as a result of non-24 h light-dark cycles, operational shifts in work/rest cycles, high workload under pressure, and psychological factors. Head-down tilt bed rest (HDBR) is an established model to mimic some of the physiological and psychological adaptions observed in spaceflight. Data on the effects of HDBR on circadian rhythms are scarce. To address this gap, we analyzed the change in the circadian rhythm of core body temperature (CBT) in two 60-day HDBR studies sponsored by the European Space Agency [n = 13 men, age: 31.1 ± 8.2 years (M ± SD)]. CBT was recorded for 36 h using a non-invasive and validated dual-sensor heatflux technology during the 3rd and the 8th week of HDBR. Bed rest induced a significant phase delay from the 3rd to the 8th week of HDBR (16.23 vs. 16.68 h, p = 0.005, g = 0.85) irrespective of the study site (p = 0.416, g = −0.46), corresponding to an average phase delay of about 0.9 min per day of HDBR. In conclusion, long-term bed rest weakens the entrainment of the circadian system to the 24-h day. We attribute this effect to the immobilization and reduced physical activity levels associated with HDBR. Given the critical role of diurnal rhythms for various physiological functions and behavior, our findings highlight the importance of monitoring circadian rhythms in circumstances in which gravity or physical activity levels are altered.

Physical Activity Levels

Physical activity is a vital part of cardiac rehabilitation (CR). However, heart-healthy physical activity levels in people with cardiovascular disease drop significantly after CR. This exploratory study employs qualitative and survey methods within a co-creation approach. The aim is to understand the mechanisms of healthy behavior and habit formation in order to create a novel evidence-based (post-)rehabilitation approach that employs digital means to sustain long-term physical activity levels in people with cardiovascular disease.

Physical Activity Levels

Background Low physical activity levels can negatively affect the health of nurses. Given the low physical activity levels reported by nurses, there is a clear need for brief and economical interventions designed to increase physical activity levels in this population. We developed a web-based intervention that used motivational strategies to increase nurses’ physical activity levels. The intervention provided the nurses with feedback from an activity monitor coupled with a web-based individual, friend, or team physical activity challenge. Objective In this parallel-group randomized trial, we examine whether nurses’ motivation at baseline predicted changes in objectively measured physical activity levels during the 6-week intervention. Methods The participants were 76 nurses (n=74, 97% female; mean age 46, SD 11 years) randomly assigned to 1 of 3 physical activity challenge conditions: (1) individual, (2) friend, or (3) team. The nurses completed a web-based questionnaire designed to assess motivational regulations for physical activity levels before the intervention and wore a Tractivity activity monitor before and during the 6-week intervention. We analyzed data using multilevel modeling for repeated measures. Results The nurses’ physical activity levels increased (linear estimate=10.30, SE 3.15; P=.001), but the rate of change decreased over time (quadratic estimate=−2.06, SE 0.52; P<.001). External and identified regulations (ß=−2.08 to 11.55; P=.02 to .04), but not intrinsic and introjected regulations (ß=−.91 to 6.29; P=.06 to .36), predicted changes in the nurses’ physical activity levels. Conclusions Our findings provide evidence that an intervention that incorporates self-monitoring and physical activity challenges can be generally effective in increasing nurses’ physical activity levels in the short term. They also suggest that drawing solely on organismic integration theory to predict changes in physical activity levels among the nurses participating in web-based worksite interventions may have been insufficient. Future research should examine additional personal (eg, self-efficacy) and occupational factors (eg, shift length and shift type) that influence physical activity levels to identify potential targets for intervention among nurses.

Abstract Objectives High blood pressure (BP) is a common health condition, especially among the aging population. Studies suggest that diet influences blood pressure. In this cross-sectional study, we investigated the association between dietary factors and BP in older adults. Methods One hundred twenty-eight participants (n = 57 males and n = 71 females) aged 65–80 were included in this study. Dietary data was collected through a validated food frequency questionnaire. Demographics, anthropometric measurements, socioeconomic factors, medication information, and physical activity levels were also collected. Multiple linear regressions were conducted to examine the associations between dietary factors including meats, vegetables, grains, fruits, dairy, fats, and added sugar and changes in blood pressure. Results There were no associations between dietary factors and systolic BP when both men and women were included in the model. However, solid fruit was associated with diastolic blood pressure (beta = −0.22, P = 0.039; 95% CI −7.9, −0.2) in both males and females, and every 0.71 cup increase in solid fruit consumption was predicted to decrease diastolic BP by 2.9 mmHg. When the model was split by sex, there was a significant association between intake of added sugar and systolic (β = 0.731, P < 0.001; 95% CI 1.8, 5.6) and diastolic (β = 0.537, P = 0.006; 95% CI 0.5, 2.8) BP in women after controlling for body mass index, physical activity levels, daily calorie intake, and BP medication use. Among all the dietary factors, a greater intake of added sugar had the most significant impact on BP in elderly females. The model predicted that a decrease of 1 standard deviation (4.6 teaspoons) of added sugar would result in a 0.731 standard deviation (17.0 mmHg) drop of systolic BP and a 0.537 standard deviation (7.6 mmHg) drop of diastolic BP. Study results could be limited by the small sample size. Conclusions Our findings support the dietary guidelines of limiting daily intake of added sugar to promote overall cardiovascular health. Future studies are needed to examine the impact of added sugar on vascular function. Funding Sources None.
