Sitting Time Reduction and Blood Pressure in Older Adults: A Randomized Clinical Trial.

Importance: Practical health promotion strategies for improving cardiometabolic health in older adults are needed. Objective: To examine the efficacy of a sedentary behavior reduction intervention for reducing sitting time and improving blood pressure in older adults. Design, Setting, and Participants: This parallel-group randomized clinical trial was conducted in adults aged 60 to 89 years with high sitting time and body mass index of 30 to 50 from January 1, 2019, to November 31, 2022, at a health care system in Washington State. Intervention: Participants were randomized 1:1 to the sitting reduction intervention or a healthy living attention control condition for 6 months. Intervention participants received 10 health coaching contacts, sitting reduction goals, and a standing desk and fitness tracker to prompt sitting breaks. The attention control group received 10 health coaching contacts to set general healthy living goals, excluding physical activity or sedentary behavior. Main Outcomes and Measures: The primary outcome, measured at baseline, 3 months, and 6 months, was sitting time assessed using accelerometers worn for 7 days at each time point. Coprimary outcomes were systolic and diastolic blood pressure measured at baseline and 6 months. Results: A total of 283 participants (140 intervention and 143 control) were randomized (baseline mean [SD] age, 68.8 [6.2] years; 186 [65.7%] female; mean [SD] body mass index, 34.9 [4.7]). At baseline, 147 (51.9%) had a hypertension diagnosis and 97 (69.3%) took at least 1 antihypertensive medication. Sitting time was reduced, favoring the intervention arm, with a difference in the mean change of -31.44 min/d at 3 months (95% CI, -48.69 to -14.19 min/d; P < .001) and -31.85 min/d at 6 months (95% CI, -52.91 to -10.79 min/d; P = .003). Systolic blood pressure change was lower by 3.48 mm Hg, favoring the intervention arm at 6 months (95% CI, -6.68 to -0.28 mm Hg; P = .03). There were 6 serious adverse events in each arm and none were study related. Conclusions and Relevance: In this study of a 6-month sitting reduction intervention, older adults in the intervention reduced sedentary time by more than 30 min/d and reduced systolic blood pressure. Sitting reduction could be a promising approach to improve health in older adults. Trial Registration: ClinicalTrials.gov Identifier: NCT03739762.

"They're Going to Zoom It": A Qualitative Investigation of Impacts and Coping Strategies During the COVID-19 Pandemic Among Older Adults.

Introduction: Older adults, who already have higher levels of social isolation, loneliness, and sedentary behavior, are particularly susceptible to negative impacts from social distancing mandates meant to control the spread of COVID-19. We sought to explore the physical, mental, and social health impacts of the pandemic on older adults and their coping techniques. Materials and Methods: We conducted 25 semi-structured interviews with a sub-sample of participants in an ongoing sedentary behavior reduction intervention. Interviews were recorded and transcribed, and iterative coding was used to extract key themes. Results: Most participants reported an increase in sedentary behavior due to limitations on leaving their home and increased free time to pursue seated hobbies (e.g., reading, knitting, tv). However, many participants also reported increased levels of intentional physical activity and exercise, particularly outdoors or online. Participants also reported high levels of stress and a large decrease in in-person social connection. Virtual connection with others through phone and video was commonly used to stay connected with friends and family, engage in community groups and activities, and cope with stress and social isolation. Maintenance of a positive attitude and perspective gained from past hardships was also an important coping strategy for many participants. Discussion: The COVID-19 pandemic and associated social distancing measures have impacted older adults' perceived levels of activity, stress, and social isolation, but many leveraged technology and prior life experiences to cope. These themes could inform future interventions for older adults dealing with chronic stress and isolation.

Refractive expectations of patients having cataract surgery.

PURPOSE: To assess the refractive expectations of patients having elective cataract surgery. SETTING: Queen's Medical Centre, Nottingham, King's Mill Hospital, Sutton-in-Ashfield, and Kidderminster District Hospital, United Kingdom. METHODS: A prospective questionnaire study of patients attending a preoperative assessment clinic for elective cataract surgery was performed. Only first-eye cataract surgery patients were included. Patients were excluded if they had visually impairing ocular comorbidity or if they were mentally unable to complete the questionnaire. RESULTS: One hundred eighty-nine questionnaires were received. Mean patient age was 74 years (range 41 to 97 years). Sixty-four percent of respondents were women, and 90% were retired. On 10-point Likert scales (0 lowest, 10 highest), median patient scores for the perceived likelihood of needing spectacles after surgery were 8 for both distance and near correction. Patients already wearing distance correction thought it significantly more likely that they would need distance glasses postoperatively than those who did not (median likelihood scores 9 and 1, respectively; P<.0001). Similar differences in expectations were demonstrated for near correction. Median score of the importance of not needing spectacles was 8 for both distance and near. Men scored this higher than women, but only for distance. There was a weak negative correlation between the importance of spectacle independence and patient age. CONCLUSIONS: Patients who already wear spectacles expect to need them after cataract surgery. Those not already wearing spectacles do not expect to need them. This latter group is at particular risk for refractive disappointment and complaint. In general, patients consider the opportunity to be free of glasses as very important.
