Question

Identify and Explain the Research Population of this Study?

"We identified senior and community centers that are in communities serving a low-income population in San Diego County. Centers in low income communities are identified by the average annual household income of the census tract around the center’s address. Centers in census tracts with annual household income below San Diego County median are considered low income. We contact all centers, either by phone or in person, to obtain basic information on their size and program offerings. Confirm the number of older adults they serve, classes offered, hours, and space available. Interested centers then fill out an application verifying eligibility criteria including: at least 1 physical activity class offered, able to recruit 35 participants and, in intervention sites, can recruit 4 health coaches and a staff member, have sufficient space for study activities and can commit to the 2 year study period. This application and a memorandum of understanding is signed so that details of the nature of the study and commitments are clear. Centers that meet the criteria are then selected and offered to participate in the study. After being randomized into either intervention or control, the center directors identify at least one staff member to attend the training and assist with the implementation and logistical coordination of the intervention at the institutional level. This staff person recommends potential peer health coaches who then meet with UCSD staff to learn about the role and complete an interview, if interested. The peer health coach role is also announced in the surrounding community and networks. No specific educational prerequisites are required for the peer health coaches. A willingness to lead and experience with teaching, coaching, or community advocacy are desired. Participant recruitment in the centers occurs through word of mouth, flyers, information tables, social media and presentations. To recruit residents who may not normally attend the center, we place advertisements in local publications and media, at churches, and in senior housing complexes. We also use marketing company data to identify participants meeting the age criteria (50+), with an address within 2 miles of the center. The marketing company uses public data sources such as census data, survey reported data, and the white pages. People who meet the age criteria receive a letter from the study team explaining the opportunity to participate in the study and the date and location of a study recruitment event. Participants are recruited primarily when the study starts at each site, but senior center members can enroll on a rolling basis at any time up to 12 months from baseline. Participant recruitment began in 2015. Older adults, 50 years and over, who are eligible according to our criteria are consented, enrolled and assessed. Eligibility criteria include: a) completing a Timed Up and Rich et al. BMC Public Health (2018) 18:29 Page 3 of 12 Go Walk test [11] within 30 s, with a walking aid if needed, b) not having had a fall resulting in a hospitalization during the previous 12 months, c) able to walk without human assistance (cane or walker use okay), d) able to provide informed written consent, e) able to complete surveys without assistance, f ) able to read and write in English or Spanish, g) able to complete study activities and wear devices, and h) complete a post-consent review comprehension test to assess comprehension of their role as a participant in the study."
