    Abstract: Purpose Accelometry is a very important tool to measure physical activity (PA) in preschoolers, as it can measure 24-hour PA and detect activity which cannot be captured by other methods. However, accelerometer validation for preschoolers is lacking (Altenburg et al. 2022). Specifically, for the ActiGraph wGT3X-BT and Move 4 (ActiGraph LLC; Move4 activity sensor, movisens GmbH) only a few, respectively no preschooler validation studies, were found. Thus, the purpose was to validate these two accelerometers in Swiss preschoolers with the System for Observing Children’s Activity and Relationships during Play (SOCARP; Ridgers et al., 2010). Methods and Design Preschoolers (2-5 years old) from two Swiss Sunday activity programs (MiniMove & Ä Halle wo’s fägt) were randomly selected as part of a larger program evaluation. PA was assessed SOCARP for a duration of 12 minutes per child. During the observation, the children wore both an ActiGraph and a Move4 device taped to their right hip to record steps. Step-counts from the ActiGraph and Move4 were correlated with each other and with moderate-to-vigorous (MV)PA from SOCARP (as SOCARP does not count steps). Results Valid PA data was available for 45/58 (77.6%) children (49% girls) for SOCARP and for 47/58 (81%) children (51% girls) for accelometry. Step count correlations between the accelerometers (Actigraph and Move4) and %MVPA (SOCARP) was medium and positive (r(43) = .34, p = .03 and r(43) = .37, p = .02; respectively). There was a strong step count correlation between the two devices (r(45) = .90, p 〈 .001), although ActiGraph measured significantly more steps than Move4 (m = 557.74, SD = 255.77 versus m = 397.81, SD = 164.10); t(46)=8.47, p 〈 .001). Discussion PA measurement in preschool children can be challenging. However, the correlation between step counts and observed %MVPA indicates criterion validity for both devices. The step-counts of Actigraph and Move4 validate each other, but there is a difference in the absolute number of measured steps. Due to different outcome parameters, calculation algorithms, and inaccessibility to raw acceleration the comparison of the two devices on movement intensity was not possible. Although promising preliminary indications of validity of device-based measurement of PA in Swiss preschool children, further investigations into the methodological approaches of comparing measurements of movement intensity are warranted.

    Abstract: Background: A heightened stress reactivity to mental stress tasks has been shown in hypertensive patients and might contribute to a higher disease risk. We investigated this hyperreactivity with regard to an attachment related stressor that focuses on emotions instead of performance and we examined whether this effect can also be found in patients on antihypertensive drugs. Materials and Methods: Fifty patients with primary hypertension, treated with at least one antihypertensive drug, were compared with 25 healthy individuals. After 10 min of rest, they participated in an attachment-related interview (Adult Attachment Projective picture system, AAP) and were exposed to an attachment-related stressor (Separation Recall, SR), a short-time stressor which activates attachment-related emotions and thoughts by talking 5 min about a personal experience of loneliness. Blood samples to measure adrenocorticotrope hormone (ACTH), cortisol, norepinephrine, epinephrine, and dopamine were taken. Blood pressure, heart rate and arterial stiffness were measured at rest, after AAP, after SR and 10 min after recovery. Standard deviation of normal-to-normal intervals (SDNN) and root mean square of successive differences (RMSSD) were calculated. Parameters were compared using Mann Whitney U -test and linear mixed-effects regression models controlling for age and body mass index (BMI) after logarithmic transformation if appropriate. Results: Healthy test persons were younger and had lower BMI than patients. Comparing the two groups there were no significant differences in blood pressure and heart rate at rest. Both stressors provoked a significant response in almost all parameters. Results of the post-estimation of contrasts from linear mixed-effects regression models showed a steeper rise in systolic BP and arterial stiffness as well as a more pronounced decline in SDNN in hypertensive patients than in healthy controls. Levels of cortisol rose earlier and higher in hypertensive patients than in healthy controls. Conclusion: Vascular, autonomic, and hypothalamic pituitary adrenal axis response is heightened in medicated subjects with hypertension in response to attachment-focused stressors compared to healthy subjects. We conclude that the remaining hyper-reactivity even with sufficient antihypertensive medication still poses a substantial risk for affected patients. New ways to diminish this risk should be developed.

    Abstract: Background Eighty-eight thousand fall accidents occur each year in Switzerland among people aged 65 and over, which cause a lot of personal suffering and economic costs  Beratungsstelle für Unfallverhütung BFU, 2019). The exercise at home program “DomiGym - Bewegungsangebot zu Hause” (in short: DomiGym) of Pro Senectute Switzerland aims to maintain mobility, counteract the risk of falls and promote social contacts as well as social participation and psychosocial health. Vulnerable, elderly people enjoy with DomiGym an adapted, regular training program focused on strength and balance, in their own homes or in their neighborhoods. Methodology The implementation and effects of the DomiGym offers in the cantons of Zug and Zurich were evaluated using various methodological approaches: tests of strength (Chair-Stand-Test; Mehmet et al., 2019), of balance (Modified Romberg; Agrawa et al., 2011) and of functional mobility (Timed-Up-and-Go-Test; Marks, 2016) as well as written surveys of participants (based on standardized scales used in the Swiss Health Survey). Results On average participants reduced fall risk and improved functional mobility and leg strength (p 〈 0.05). In a subsample of the canton of Zug, the Timed-Up-and-Go-Test (functional mobility and fall risk) improved by an average of 2.3 seconds (p 〈 0.005) and the balance test (Romberg) improved by 1.8 seconds (p = 0.005). Over the course of a training series the reduction in fall risk proved clinically relevant in both cantons. Scores on the Timed-Up-and-Go-Test fell on average below the threshold of 13.5 seconds discriminating between fallers and non-fallers. Chair-stand test: Participants improved on average from an initial very high fall risk to an increased fall risk (below 15 seconds). In fact the subsample of canton Zug improved by an average of 3.96 seconds (clinically relevant with regard to the reduction of falls) and the subsample of canton Zurich improved by an average of 2.17 seconds (approximately clinically relevant; threshold value 2.3 seconds; Meretta et al., 2006). DomiGym improved the general health (67%) of most participants and either maintained the original walking level (80%) or even improved it (15%). The majority of DomiGym participants do gymnastic exercises at least weekly outside of DomiGym training. DomiGym participants positively change their movement behavior in everyday life. Conclusions Pro Senectute’s DomiGym reaches older people who cannot or do not want to attend out-of-home physical activity programs. The implementation of DomiGym improves the physical functions of leg strength, functional mobility, and balance, as well as the risk of falls in vulnerable elderly people. It can be assumed that DomiGym reduces the frequency of falls in the long term, contributes to the preservation of mobility and independence in everyday life, including a longer stay in their own homes.

    Abstract: Physical activity guidelines are recognized as an important element of a national approach to promote physical activity. This publication summarizes the approach and process taken to update the Swiss Guidelines, presents a summary of the updated guidelines and discusses experiences and identifies challenges. The multistage project involved: 1) to summarize the scientific evidence underpinning the 2020-edition of the WHO guidelines; 2) to systematically analyze the existing Swiss guidelines for different target groups and to develop proposals for updates 3) a participatory process to gain consensus with the main interested groups 4) to finalize the guidelines. Updated guidelines were adopted for infants, pre-school children, children and young people, adults, older adults and pregnant and postpartum women, in most cases following the WHO guidelines. Children, young people and adults living with disability and adults and older adults with chronic conditions are specifically addressed in each of the general guidelines for healthy populations, rather than developing separate guidelines for each of these groups as done by the WHO. The systematic approach in identifying aspects to update, the participatory approach and a scientific consortium and project coordination group with different thematic backgrounds were key strengths in the process. Challenges included the large amount of feedback and finding scientifically sound compromises. The updated versions of the Swiss national guidelines provide an excellent basis to further promote physical activity in Switzerland. A remaining key task is to develop a range of communication tools and materials for different target groups beyond the circle of experts and interested groups, considering available evidence on optimal messaging and best outlet tools and channels. To track population prevalence, inform policy and evaluate physical activity promotion at national and sub-national level in a timely fashion, strengthening existing physical activity monitoring will be important.
