BACKGROUND: It is known that 24-hour movement behaviors, including physical activity (PA), sedentary behavior (SB), and sleep, are crucial components affecting older adults\' health. Canadian 24-hour movement guidelines for older adults were launched in 2020, emphasizing the combined role of these 3 movement behaviors in promoting older adults\' health. However, research on the prevalence and correlates of guideline adherence and its associations with health-related outcomes is limited, especially among Chinese older adults.
OBJECTIVE: This study aimed to investigate the prevalence and correlates of meeting 24-hour movement guidelines among Chinese older adults. Furthermore, this study aimed to examine the associations of guideline adherence with older adults\' physical and mental health outcomes.
METHODS: Using a stratified cluster random sampling approach, a total of 4562 older adults (mean age 67.68 years, SD 5.03 years; female proportion: 2544/4562, 55.8%) were recruited from the latest provincial health surveillance of Hubei China from July 25 to November 19, 2020. Measures included demographics, movement behaviors (PA, SB, and sleep), BMI, waist circumference, waist-hip ratio (WHR), percentage body fat (PBF), systolic and diastolic blood pressure, physical fitness, depressive symptoms, and loneliness. Generalized linear mixed models were employed to examine the associations between variables using SPSS 28.0 (IBM Corp).
RESULTS: Only 1.8% (83/4562) of participants met all 3 movement guidelines, while 32.1% (1466/4562), 3.4% (155/4562), and 66.4% (3031/4562) met the individual behavioral guidelines for PA, SB, and sleep, respectively. Participants who were older, were female, and lived in municipalities with lower economic levels were less likely to meet all 3 movement guidelines. Adhering to individual or combined movement guidelines was associated with greater physical fitness and lower values of BMI, waist circumference, WHR, PBF, depressive symptoms, and loneliness, with the exception of the relationship of SB+sleep guidelines with loneliness. Furthermore, only meeting SB guidelines or meeting both PA and SB guidelines was associated with lower systolic blood pressure.
CONCLUSIONS: This is the first study to investigate adherence to 24-hour movement guidelines among Chinese older adults with regard to prevalence, correlates, and associations with physical and mental health outcomes. The findings emphasize the urgent need for promoting healthy movement behaviors among Chinese older adults. Future interventions to improve older adults\' physical and mental health should involve enhancing their overall movement behaviors and should consider demographic differences.

The new guidelines on hypertension of the European Society of Cardiology (ESC) 2018 have refined the treatment cut-offs and therapy decisions in adults. This review highlights important recommendations of the guidelines and also on the situation of hypertension in Austria. The general treatment targets of blood pressure have been lowered to at least 130/80 mmHg for most patients. The definition of hypertension is specified as a repeated systolic blood pressure in the office of ≥140 and or diastolic BP ≥90 mmHg. For home blood pressure monitoring, an average value of ≥135/85 mmHg is now defined as hypertension. Ambulatory 24h-blood pressure measurement is recommended for diagnosis of hypertension and to demask lack of nocturnal blood pressure dipping. Whether drug treatment should be initiated immediately or after a delay with lifestyle intervention is focused on the individual high or low cardiovascular risk of the patients and the degree of hypertension. For most patients a combination therapy with single pill is now recommended as initial therapy for hypertension from the start. The salt consumption should be reduced in the majority of patients. The new guidelines have clarified the treatment of hypertension in different comorbidities.
