South Asian Women Together in a Health Initiative: A Pilot RCT

Background. Canadian South Asian women have high rates of cardiovascular disease morbidity and mortality and the lowest rates of physical activity in Canada, which increases risk for type II diabetes mellitus, hypertension, obesity and cardiovascular disease.

The overall goal of this pilot randomized controlled trial is to assess the feasibility and acceptability of a culturally tailored 12-week peer-based physical activity intervention, among 48 sedentary Canadian South Asian women, ages 24 to 39, in the Greater Toronto Area. Specific objectives are to determine: 1) The feasibility (recruitment, retention, engagement, and acceptability) of implementing the South Asian women Together in a Health Initiative (SATHI) intervention, and 2) The effect of SATHI on physical activity (step count, moderate/vigorous physical activity, weight/resistance training), anthropometric risk (waist circumference, waist-to-hip ratio, body mass index), and self-efficacy (Physical Activity Appraisal Inventory).

Sample and Setting. Participants will include: 1) Canadian South Asian women, 2) aged 24 to 39 years, 3) sedentary, 4) without unstable medical or chronic conditions, and 5) residents of the Greater Toronto Area. All participants will be screened for safety using the Physical Activity Readiness Questionnaire-Plus screening tool. Peers will be: 1) Canadian South Asian women, 2) aged 24 and 39 years, and 3) who self-report achieving at least 30 minutes continuous moderate to vigorous physical activity five days per week. This trial will be conducted at community centres in the Greater Toronto Area.

Research Design. A pragmatic two-arm parallel 12-week pilot randomized controlled trial.

Recruitment. South Asian community centres will be used for participant and peer recruitment, data collection and intervention follow-up. Other strategies for participant and peer recruitment will include flyers distributed at the Punjabi Community Health Services, the multiservice centres at Peel Public Health, religious festivals, local mosques, temples, and gurudwaras, churches, South Asian restaurants, and grocery and clothing stores within the Greater Toronto Area. Popular female South Asian online personalities will also promote the study on social media.

Procedures. Upon completion of participant and peer recruitment, consent and collection of baseline demographic, anthropometric, and self-efficacy for exercise data, participants will be randomly allocated to either a control or intervention group, using block sizes of 4 and 8. All participants will receive a study pedometer, instructions on its use, and a physical activity logbook in which they will document daily step counts and physical activity. Control Group. Participants allocated to the control group will receive the Canadian Society of Exercise Physiology/ParticipACTION physical activity guidelines for adults ages 18 to 64. Intervention Group. Participants allocated to the intervention group will receive the: 1) South Asian physical activity education which includes a culturally specific physical activity education booklet and video and 2) peer support. Peers will encourage physical activity and provide motivation and suggestions for incorporating physical activity into daily life of a South Asian woman using Bandura's Self-Efficacy construct. Peer contact will occur via telephone/text/email messaging or in person at least once a week and more often as determined by participants. All peers will receive 4-hours of training and will be matched to participants based on presence of child(ren). Peers will not provide medical advice and will document all participant-peer interactions on a log sheet that will be submitted to the trial investigator.

Outcomes. Participants in control and intervention groups will submit baseline step counts. After randomization, intervention group participants will submit weekly step counts to the research assistant. All other outcome data will be collected at 12-weeks. Primary Outcomes. Participant and peer recruitment, retention, engagement, and acceptability rates for the SATHI intervention. Secondary Outcomes. Physical activity (step count, physical activity logbook), anthropometric measures (waist circumference, waist-to-hip ratio, body mass index) and self-efficacy (Physical Activity Appraisal Inventory).

Data Analysis. All statistical analysis will be completed using SPSS Statistics v.24. Descriptive statistics will be conducted to analyze baseline outcome measures. Paired t-tests will be used to assess between-group mean differences. Mean change scores (T2-T1) for both control and intervention groups will be calculated for within group differences. Since this is a feasibility trial, a p-value will be set at p<0.10.
