Web-Based Physical Activity Intervention for Latina Adolescents: Feasibility, Acceptability, and Potential Efficacy of the Niñas Saludables Study

BACKGROUND Physical activity is markedly low in Latina adolescents, yet few physical activity interventions have been attempted in this population. Web-based interventions can incorporate theory-based components, be appealing to adolescents, and have potential for low-cost dissemination. OBJECTIVE This study aimed to assess the feasibility, acceptability, and potential efficacy of a Web-based physical activity intervention for Latina adolescents in a single-arm pilot trial. METHODS A total of 21 Latina adolescents (aged 12-18 years) who could read and write in English and were underactive (<90 min/week) participated in a 12-week, theory-informed Web-based physical activity intervention. The intervention website was modified from a previous Web-based intervention for Latina adults. Web content was individually tailored based on the responses to monthly questionnaires. Feasibility was measured by recruitment, retention, and adherence/engagement, and acceptability was measured by satisfaction surveys. Physical activity was measured at baseline and follow-up (12 weeks) using the 7-day physical activity recall (PAR) interview and accelerometers. RESULTS Baseline activity as measured by the 7-day PAR and accelerometers was 24.7 (SD 26.11) and 24.8 (SD 38.3) min/week, respectively. At 12 weeks, 19 participants (90%, 19/21) returned. Adherence and engagement with materials were low, but 72% (15/21) of the participants indicated that they were satisfied with the intervention. Activity at 12 weeks increased by 58.8 (SD 11.33) min/week measured by the 7-day PAR (P<.001). Accelerometer-measured activity did not increase. Activities reported at follow-up were more varied than at baseline, including some activities measured poorly by accelerometers (eg, biking and swimming). Participants suggested simplifying the website and incorporating other technologies. CONCLUSIONS Good retention and increases in self-reported activity suggest a promising approach to delivering a physical activity intervention to Latina adolescents. Incorporating other technologies, such as smartphone apps, could make the intervention more engaging, acceptable, and effective.

IntroductionPhysical activity is an integral part of healthy ageing, yet the majority of older adults 65+ years are not sufficiently active. Web-based physical activity interventions hold much promise to reach older adults. Preliminary evidence suggests that web-based interventions with tailored advice and Fitbits may be well suited for older adults.Methods and analysisThis study aims to test the effectiveness of ‘Active for Life’, a 12-week computer-tailored web-based physical activity intervention using Fitbits for older adults. We will recruit 300 participants who will be randomly assigned to one of three trial arms: (1) web-based physical activity intervention with tailored advice only, (2) web-based physical activity intervention with tailored advice and Fitbit or (3) a wait-list control. The primary outcome, objective moderate to vigorous physical activity (MVPA) and secondary outcomes of objective sedentary behaviour, objective sleep, quality of life, social support, physical function and satisfaction with life will be assessed at baseline and week 12. The secondary outcomes of self-reported physical activity, sitting time and sleep will be assessed at baseline, week 6, 12 and 24. Website usability and participant satisfaction will be assessed at week 12 and website usage and intervention fidelity will be assessed from week 1 to 24. Intention-to-treat linear mixed model analyses will be used to test for group (tailoring only, tailoring +Fitbit, control) differences on changes in the main outcome, MVPA and secondary outcomes. Generalised linear models will be used to compare intervention groups (tailoring only, tailoring +Fitbit) on website usability, participant satisfaction, website usage and intervention fidelity.Ethics and disseminationThe study has received ethics approval from the Central Queensland University Human Research Ethics Committee (H16/12-321). Study outcomes will be disseminated through peer-reviewed publications and academic conferences and used to inform improvements and dissemination of a tailored, web-based physical activity intervention for adults 65+ years.Trial registration numberAustralian and New Zealand Clinical Trials Registry Number: ACTRN12618000646246

Background:The purpose of this study was to examine the feasibility and effectiveness of a web-based intervention to promote physical activity and self-worth among working mothers.Methods:Participants (N = 69) were randomly assigned to receive a standard web-based intervention or an enhanced intervention that included group dynamics strategies to promote engagement. The 8-week intervention was guided by self-determination theory. Each week, participants were instructed to complete 3 tasks: listen to a podcast related to well-being, complete a workbook assignment, and communicate with other participants on a discussion board. Participants in the enhanced condition received an additional weekly task to enhance group cohesion. Data were collected at baseline, week 8, and week 16.Results:Physical activity (P < .001, η2 = 0.35) and self-worth (P < .001, η2 = 0.39) increased significantly in both groups following the intervention, and introjected (P < .001, η2 = 0.30) and external motivation (P = .04, η2 = 0.10) decreased. Website use declined across the 8-week intervention in both groups (P < .001, η2 = 0.48); however, discussion board use was higher in the enhanced condition (P = .04, η2 = 0.21).Conclusions:These findings suggest web-based interventions can improve physical activity and self-worth among working mothers. Group dynamics strategies only minimally enhanced user engagement, and future studies are needed to optimize web-based intervention designs.

Latina Adolescents

BACKGROUND Adolescent girls report the lowest levels of physical activity (PA) of any demographic group, with rates especially low for racial/ethnic minority girls. Only 3% of Latina teens meet national PA guidelines, and these habits appear to persist into adulthood. Developing effective interventions to increase PA in Latina teens is necessary for preventing disease and reducing disparities. OBJECTIVE The study objective was to develop a mHealth PA intervention for Latina adolescents using a multi-stage iterative process based on an adaptation of the IDEAS (Integrate, DEsign, Assess, Share) framework. METHODS Development of the intervention was accomplished through three iterations: 1) feedback from a previous web-based pilot study, Niñas Saludables; 2) conducting focus groups with the target population; and, 3) vetting the final materials with a youth advisory board (YAB) comprising Latina adolescents. Based on feedback from participants in the Niñas Saludables study, plans to improve the intervention included incorporating visual social media posts and text messaging, adding a commercial wearable tracker, and revising the existing website to be primarily visual; proposed procedures and material were then refined through focus groups. Participants for focus groups (N=50) were girls age 13-18 who could speak and read in English who were recruited from local high schools and after school programs serving a high proportion of Latinos. Facilitated discussions focused on experience with PA and social media apps, and specific feedback on intervention material prototypes and possible names and logos. Materials were refined based on their feedback, then were beta tested by the YAB. YAB members (N=4) were Latinas age 13-18 who were not regularly active and were recruited via word of mouth and selected through an application process. RESULTS The focus group discussions yielded the following findings: PA preferences included walking, running and group fitness classes, while the least popular activities were running, swimming, and biking. Most participants used some form of social media, with Instagram being the most favored. Participants preferred text messages be sent no more than once a day, be personalized, and be positively worded. Focus group participants preferred an intervention directly targeting Latinas, and social media posts that were brightly colored, included girls of all body types, and provided specific tips and information. Modified intervention materials were generally perceived favorably by the YAB members, who provided suggestions for further refinements including incorporation of some Spanish phrases. CONCLUSIONS Latina teens were generally enthusiastic about an mHealth PA intervention, provided the materials were targeted specifically to them and their preferences. Through multiple iterations of development and feedback with the target population, we gained insight into the needs of Latina teens and joined with industry partners to build a viable final product.

Background Tailoring an online intervention to participant preferences (eg, by giving participants a choice which modules to follow) may increase engagement in the intervention, motivation for behavioral change, and possibly intervention effects. So far, little is known about what characteristics predict these module choices. Filling this knowledge gap is useful for optimizing program engagement. Objective We investigated participant choice for a dietary and/or physical activity (PA) promotion module in our web-based computer-tailored intervention based on self-determination theory (SDT) and motivational interviewing (MI). Furthermore, we investigated which demographic characteristics, current behavior, psychosocial constructs and constructs from SDT and MI, and program-related variables such as advice on which module to follow were associated with these choices. Methods Observational data were used from the randomized controlled trial MyLifestyleCoach of participants who were randomized into the intervention condition, completed the baseline questionnaire, and made a module choice in the opening session of the intervention. Here, they received advice on their own dietary and PA behavior. At the session’s end, they chose which lifestyle modules they would like to follow (both, diet, PA, or no module). Measurements included demographic information; self-reported diet and PA; and several psychosocial, SDT, and MI constructs. In total, data from 619 Dutch adults (59.6% women; mean age was 51.9 [SD 13.5] years) were analyzed. A stepwise multinomial logistic regression analysis was conducted to investigate which characteristics are related to module choice; the diet module served as reference category as almost everyone was advised to follow this module. Results Of this sample, 54.8% (339/619) chose to do both the diet and PA module, 25.4% (157/619) chose to follow the diet module, 17.8% (110/619) preferred to follow no module, and 2.1% (13/619) chose to do the PA module only. Furthermore, it was found that older people, those who consumed more fruit, and those who scored lower on importance to change their current diet were more likely to choose no module compared to the diet module. People who had more motivation to change their current PA and those who received strong advice compared with slight advice to follow the diet module were more likely to choose both modules compared with the diet module only. Conclusions The results show that more than half of the sample was interested in following both the diet and PA module in this online lifestyle intervention. Several characteristics were found to be related to module choice. A future challenge is to examine how this knowledge can be used to improve future interventions, such as tailoring (messages or content) on specific groups or examining where and how MI could be used to motivate people to make a certain module choice.

BACKGROUND Despite the crucial role of regular physical activity (PA) for preventing chronic non-communicable diseases, fewer than half of older adults in Germany engage in the recommended levels of endurance training. OBJECTIVE The aim of this study was to compare acceptance and effectiveness of two interventions (web- vs. print-based) for PA promotion among initially inactive community-dwelling older adults aged 60 years and above in a nine-month randomized trial with a cross-over design. METHODS Participants were recruited offline and randomized to one of the following interventions for self-monitoring PA: (a) a print-based intervention (PRINT n=113), (b) a web-based intervention (WEB, n=129). Thirty percent (n=38) of those in group (b) received a PA tracker in addition to WEB (WEB+, (c)). After randomization, participants and researchers were not blinded. Participants’ intervention preferences at baseline were assessed retrospectively. All intervention groups were offered ten weekly face-to-face group sessions led by trained assistants. Afterwards, participants could choose to stay in their group or cross over to one of the other groups and group sessions were continued monthly for another six months. Three-dimensional accelerometers to assess PA and sedentary behavior (SB) at baseline (T0), three-month (T1) and nine-month follow-ups (T2) were employed. Adherence to PA recommendations, attendance of group sessions, and acceptance of the interventions were assessed via self-administered paper-based questionnaires. Linear mixed models were used to calculate differences in moderate-to-vigorous PA (MVPA) and SB between time points and intervention groups. RESULTS One-hundred and ninety-five participants completed T1. Only n=1 changed from WEB to PRINT and n=15 moved from PRINT to WEB (WEB-WEB: n=103, PRINT-PRINT: n=76) when offered to cross over at T1. One-hundred and sixty participants completed T2. MVPA in min per day increased between baseline and T1, but these within-group changes in time disappeared after adjusting for covariates. MVPA decreased by 9 min per day between baseline and T2 (βtime = -9.37, 95% CI: [-18.58; -0.16]), regardless of intervention group (WEB vs. PRINT: βgroup*time = -3.76, 95% CI: [-13.33; 5.82], WEB+ vs. PRINT: βgroup*time = 1.40, 95% CI: [-11.04; 13.83]). Nineteen percent of the participants met PA recommendations at T0, 20% at T1, and 20% at T2. For SB, there were no significant group differences and group-by-time interactions, neither at T1 nor at T2. Intervention acceptance was generally high. Use of intervention material was high to moderate at T1 (e.g., the PA diary was used by over 65% at least once a week) and decreased by T2 (40-50% in PRINT and in WEB used the PA diary at least once a week, and 58% in WEB+). CONCLUSIONS Despite high levels of acceptance of web- and print-based interventions for PA promotion and little movement between groups at T1, when given the choice, participation was not associated with increases in PA or decreases in SB over time.
