P10-01 Acceptability of videoconferencing physical activity intervention among elderly in rural areas: qualitative study

Abstract Background Elderly's sustainable engagement in an active lifestyle is a complex phenomenon, implying a plurality of physical, psychological and environmental barriers and facilitators. One of the key factors limiting physical activity (PA) in rural area is the lack of accessibility to PA offers. The use of videoconferencing is a promising solution in terms of acceptability and efficiency to promote PA. However, the acceptability (initial stage of the technology adoption process) of the videoconferencing is still underexplored, as well as its role in promoting PA in rural areas. The purpose of this study was to explore, through the perceptions of the elderly and policymakers, the mechanisms of acceptability of the development of PA interventions using videoconferencing for elderly living in rural areas. Methods Elderly (n = 10) and policymakers (n = 12) from 11 different rural town of the South of France participated in the study. Semi-structured individual interviews were conducted, where a video presentation of PA interventions using videoconferencing was played as support. The interview guide assessed the acceptability of this type of intervention through the following themes: (1) perceptions of benefits, (2) barriers, and (3) intentions of use. Results Preliminary results showed shared perceptions between elderly and policymakers for barriers (e.g., lack of real social ties, lack of technological equipment) and benefits (e.g., breaking loneliness, overcome weather conditions). However, intentions of use are heterogeneous according to individual characteristics (e.g., “young” elderly between 60 to 65 years are more favourable to the use of technologies) and the specificity of towns (e.g., in the smallest towns with less than 500 people, elderly are less inclined to change their habits). Conclusions This study showed that the development of videoconferencing PA intervention could be accepted by elderly living in rural areas, taking into account some conditions (e.g., offer as punctual and non-regular use, set up individual support for the use of technology). Additional quantitative studies should be conducted for a more comprehensive understanding of the factors influencing the videoconferencing PA intervention acceptability in rural areas.


Background
During the COVID-19 pandemic, many white-collar workers were requested to exclusively work from home (WFH), which may have affected their sedentary behavior. In Sweden, having less severe restrictions than many other countries, workers were allowed to alternate between WFH and work at the office (WAO), so called hybrid work. Understanding how hybrid work influences total sedentary behavior and its temporal distribution is an important issue for future health promotion. This study aimed to investigate to what extent office workers changed their temporal pattern of sedentary behavior during days WFH compared to WAO, considering age and gender as potential moderators. Methods Data were collected from May to December 2020 in office workers (n = 199). Their mean age was 42 (SD 10) years and 55% were women. Physical behaviors were measured using a thigh-worn accelerometer (AxivityAX3) for seven consecutive days. A diary identified working hours, time-in-bed and days WFH or WAO. Time-use was classified as short (0-5 min), moderate (5-30 min) and long bouts (>30 min) of sedentary behavior (SB), non-SB, and time-in-bed during workdays (WAO and WFH) and non-workdays. We used Compositional data analysis to express data as 24-hour compositions and linear mixed models to estimate difference in 24-hour compositions between day types (within worker), including age and gender as covariates and moderators.

Results
We found that workdays (WFH and WAO) were associated with proportionally less time-in-bed relative to time awake, more time SB relative to non-SB, and more time in longer relative to shorter sedentary bouts, compared to non-workdays (all p > 0.001). WFH was associated with more time-in-bed relative to awake and more SB relative to non-SB than WAO (p > 0.05), but the differences for sedentary bouts were not significant. Younger workers and women had more SB, and women accumulated more time than men in longer relative to shorter bouts of SB. However, age and gender did not affect differences between day types.

Alternative delivery channels may increase the ''reach'' of interventions into older adult populations in areas which lack trained instructors. Using technology is one alternative to traditional, face-to-face group classes where instructors and participants are in the same room. We delivered a PA program via the Internet for older adults in rural West Virginia (USA). This alternative could help other countries reach more older adults and reduce falls. Description of the problem Tai Ji Quan: Moving for Better Balance Õ (TJQMBB) is an evidence-based intervention for older adults that reduces falls.
Adults, 55 years, attended free, 1-hour tele-TJQMBB sessions, twice weekly, for 16 weeks at 5 remote community sites (3 urban, 2 rural). Trained instructors (new to TJQMBB) led 6 classes from a classroom for participants at remote sites. Instructors/sites used minicomputer, web camera, microphone, and television(s) for live, 2-way verbal/audio exchange. A CPR-certified person was present with participants. This project identified barriers to implementing tele-TJQMBB. Data on barriers were collected from instructors' class logs and summarized.

Results
Fifty-two adults (81% female, mean age 70) attended 23 (median) of 32 sessions. Barriers that caused session cancelations included: participant vacations/unavailability (n = 7), inclement weather (n = 4), technical issues (n = 2), no CPR person (n = 1), classroom not available (n = 1), site closed for state holiday (n = 1), competing event at site (n = 1), and ill instructor (n = 1). Technical barriers during sessions included interruptions/lack of audio, video freezing, and Wi-Fi/Internet connectivity problems. Two participants did not like videoconferencing. Lessons Tele-TJQMBB may be easier to teach with instructors who have already taught the program in-person. Selecting instructors/sites that are comfortable with technology may reduce technological barriers. Some older adults may still prefer faceto-face classes. Most cancelations were due to reasons normally encountered in face-to-face classes. Use of technology added new barriers that will need addressed for future classes.

Main messages
Technology reached older adults in areas with no instructors.

Online health communities offer a virtual system where people with common interest, specific health needs can exchange information and experiences with other people with the same condition as well as getting support from peer and professionals. The objective of this study is to develop an ICT platform enhancing community resident participation involving in the chronic disease prevention and physical activities. The aim of this platform is to promote physical activity of community residents for health promotion and disease prevention goal attainment. Health promotion goals for enhancing physical activity were set by health care professionals based on scientific evidence. Instead of individual plan to set the goal by themselves, the platform offered them tailored goal with their conditions and then suggested them to participate in group shared their physical activity goals. The platform encouraged the active participation of community residents though adherence physical activity of health communities in which they were members.The ICT platform provides a place where community residents with chronic conditions or even healthy people who want to promote their health be able to find an appropriate group for together prevent disease and enhancing physical activity. The platform in the study allowed community residents to develop their own communities and invite other members to participate with
