Physical Activity Recall

UNSTRUCTURED Introduction: Latino men in the U.S. report low physical activity (PA) levels and related health conditions (e.g., diabetes, obesity). Engaging in regular PA can reduce the risk of chronic diseases and yield many health benefits; yet, there is a paucity of interventions developed exclusively for Latino men. To address the need for culturally relevant PA interventions, we developed Hombres Saludables, a 6-month Spanish-language, theory-based, tailored web and text message PA intervention for Latino men. This paper describes the study design, intervention, and evaluation methods for Hombres Saludables. Methods: Latino men ages 18-65 are randomized to either the individually-tailored PA internet intervention arm or the nutrition and wellness internet control arm. The PA intervention includes: 2 check-in phone calls, automated SMS text messages, a pedometer, a 6-month gym membership, access to a private Facebook group, and an interactive website with PA tracking, goal setting, and individually-tailored PA content. Outcomes: The primary outcome is minutes/week of moderate-to-vigorous PA (MVPA) assessed via ActiGraph GT3X+ accelerometer and 7-Day Physical Activity Recall at baseline and 6-months. Secondary outcomes will examine potential moderators (e.g., demographics, acculturation, and environmental variables) and mediators (e.g., self-efficacy, cognitive and behavioral processes of change) of treatment effects at 6-months post-randomization. Conclusions: Hombres Saludables uses an innovative, interactive web and text message-based intervention for improving PA among Latino men, an underserved population at risk of low PA and related chronic disease. If the intervention demonstrates feasibility, acceptability, and preliminary efficacy, we will refine and evaluate it in a larger randomized control trial.

Background: Physical activity (PA) and exercise are widely documented as key components in the management of cystic fibrosis (CF). In recent years there have been significant improvements in telehealth, in particular; wearable technology,  smartphone use and remote monitoring, all of which may have potential to impact on PA in adults  with CF. The objective of this pilot randomised trial is to explore the effect of wearable technology, which is remotely monitored, combined with personalised text message feedback and goal setting, on PA in adults with CF. Secondary endpoints include lung function, aerobic capacity, quality of life, body composition, wellbeing and sleep. Methods: This is a pilot randomised trial which will be conducted at the University Hospital Limerick, Ireland. Participants will be randomised to the intervention or active comparator after their baseline assessment. The 12-week intervention will consist of wearable technology (Fitbit Charge 2) which is linked to an online monitoring system (Fitabase) that enables the physiotherapist to remotely monitor participant data. The CF physiotherapist will set individualised PA goals with each participant at baseline and will send text message feedback each week. The text messages will be personalised, one-way texts with positive reinforcement on step count attained by the participant. The active comparator group will receive this wearable technology which is also linked to Fitabase; however, no feedback will be provided to participants in this group. Both groups will be re-assessed at 12 weeks. After this point, both groups will continue with the Fitbit alone for a further 12 weeks. Both groups will be re-assessed at 24 weeks. A semi structured interview will assess satisfaction and acceptability of the intervention. Discussion: This is a novel concept which utilises modern technology, remote monitoring and personalised feedback to investigate the effect on PA  in adults with CF.  Trial registration: ClinicalTrials.gov NCT03672058 (14/09/2018)

Text Messages

Background: Most individuals with type 2 diabetes (T2D) struggle to adhere to one or more health behaviors. Text message interventions (TMIs) have the potential to improve adherence but have had mixed effects on diet and activity in T2D. We developed an eight-week, adaptive, algorithm-driven TMI to promote physical activity, diet, self-care, and well-being. Then, in a single-arm trial, we assessed its feasibility, acceptability, and preliminary efficacy in 15 individuals with T2D and suboptimal adherence. Methods: Participants received daily text messages and were asked to rate the utility of each message (0=not helpful, 10=very helpful). These ratings were used by an algorithm to select subsequent messages based on each participant’s prior ratings. We assessed intervention feasibility by rates of message transmission/response and acceptability through ratings of message utility and burden. Finally, we examined pre-post changes in diabetes self-care, diet, physical activity, and psychological outcomes and calculated effect sizes (Cohen’s d). Results: All text messages were delivered, and participants provided ratings for 79% of messages, above our a priori thresholds for feasibility. Participants rated the individual messages and overall TMI as subjectively useful (utility: 8.1 [SD=2.1] and 7.8 [SD=2.0], respectively) and not burdensome (burden: 0.8 [SD=1.8]). The intervention led to significant, medium- to large-sized improvements in self-care ( d=0.77), diet ( d=0.99), and activity ( d=0.61) but minimal change in psychological outcomes. Conclusions: The TMI was feasible and well-accepted, and it led to promising improvements in adherence-related outcomes. These findings should be confirmed in a larger randomized controlled trial.

Introduction: Text-message interventions with universal decision rules (treatment algorithms) demonstrate modest and inconsistent effects on physical activity. Efforts to increase effect sizes by targeting, tailoring or generically customizing content have largely been unsuccessful. In this study, system identification methods from control systems engineering were applied to develop person-specific dynamical models of individual responses to motivational text messages. Methods: Emerging adults not meeting aerobic physical activity guidelines (verified by accelerometer during a 1-week run-in period) received 0-6 messages/day while wearing a Fitbit Versa watch for 3 months. Experimental messages targeted cognitive or affective determinants of physical activity (move more) or sedentary behavior (sit less); comparator messages were inspirational quotes. For each participant, two dynamical models were estimated using difference equations: one to model the effects of move more and sit less messages and the other to model the effects of affectively- and cognitively-targeted messages. Both models included comparator messages. Effects represent the expected change in behavior immediately after message receipt (vs expected behavior without a message). Model order was determined individually to balance uncertainty and overfitting (range = 2-9). Results: The sample (n = 20) was mostly female (60%), White (65%), and not Hispanic or Latino (95%) with a mean age of 24.4 years (SD = 3.3; range = 19-29). Idiographic patterns of behavior change were readily observed from the personalized dynamical models. Most participants’ step counts increased after messages to move more (60% of participants’ responses exceeded the 95% error interval [responders], M = 94.3 steps; 83% of responders increased steps) and sit less (50% responders, M = 114.6 steps; 90% of responders increased steps), as well as control messages (75% responders, M = 59.5 steps; 60% of responders increased steps). Step counts also increased after messages targeting cognitive determinants (80% responders, M = 97.1 steps; 75% of responders increased steps) and affective determinants (75% responders, M = 52.9 steps, 67% of responders increased steps), as well as control messages (75% responders, M = 57.8 steps; 60% of responders increased steps). Conclusions: Motivational text messages can alter physical activity dynamics, and responses to different message types are highly personalized. Among responders, most message types increased expected step counts but some messages were iatrogenic and decreased expected step counts. Computational models of those dynamics provide a foundation for personalizing decision rules to select the type and time the delivery of messages to promote physical activity and improve cardiovascular health.

Concussion Recovery

ObjectiveInvestigate the potential factors influencing resolution of chief concussion symptoms in a longitudinal design. Second, assess subjects’ perception of their concussion recovery and what types of activities and accommodations appeared beneficial.BackgroundAthletes re-entering the academic setting after a concussion is commonly referred as return-to-learn (RTL), which has appeared secondary to the abundantly researched return-to-play protocols implemented ubiquitously. Importantly, every concussed collegiate, adolescent, and pediatric athlete is first and foremost a student-athlete, with “student” holding the emphasis. To date, very few studies have examined the RTL aspect of concussion recovery, and the effects premature classroom attendance may cause.Design/MethodsNine concussed, college aged (18-26 years), full-time students were monitored longitudinally throughout their recovery from diagnosis to full symptom-free academic participation. Symptom severity for five prevalent symptoms were recorded 4 times per day, along with a daily phone call to report participant’s diet, duration of screen-time usage and music listened to, physical activity participation, and types of classes attended.ResultsResponse rates to text messages and phone calls yielded a mean 92% and 93% respectively across the nine subjects. Additionally, five variables were significantly associated with symptom resolution (music, sleep, physical activity, water, and time) (p = 0.0004 to p = 0.036). Lastly, subjects reported math and computer-oriented courses as the most difficult (33% and 44% respectively). Additional time on assignments/exams and reducing screen brightness were the most beneficial accommodations (66% and 56% respectively).ConclusionsOur findings introduce a novel and robust approach to monitoring concussed students throughout their recovery. Furthermore, this methodology is the first to produce holistic evidence-based results concerning re-integrating students to the classroom. Lastly, it appears that dietary and social behaviors can indeed influence symptom resolution.

Text Message Reminder

Non-adherence is a factor that inhibits the completion of TB cases globally. Some studies suggest that the use of digital technology in the form of text message reminders can reduce the risk of non-adherence. The purpose of writing this article is to analyze the effectiveness of text message reminders on adherence to tuberculosis (TB) patients. The method in preparing this Systematic review is based on literature studies from various electronic databases, including Scopus, ScienceDirect, ProQuest, and Sage by conducting a comprehensive review using the PRISMA guidelines. The keywords used are "Text Messaging" AND "medication adherence" AND "tuberculosis". There are 11 original articles with 9 articles using the Randomized Control Trials (RCTs) research method and 2 articles using the Quasy-experimental method that fits the inclusion criteria. The use of text message reminder interventions is effective and can be used as an optional method of increasing adherence to TB patients.

Background We conducted a pilot 2-arm randomized controlled trial to assess the feasibility of a digital health intervention to increase moderate-to-vigorous physical activity in patients with colorectal cancer (CRC) during chemotherapy. Objective This study aimed to determine whether a digital health physical activity intervention is feasible and acceptable during chemotherapy for CRC. Methods Potentially eligible patients with CRC expected to receive at least 12 weeks of chemotherapy were identified in person at the University of California, San Francisco, and on the web through advertising. Eligible patients were randomized 1:1 to a 12-week intervention (Fitbit Flex, automated SMS text messages) versus usual care. At 0 and 12 weeks, patients wore an Actigraph GT3X+ accelerometer for 7 days and completed surveys, body size measurements, and an optional 6-minute walk test. Participants could not be masked to their intervention arm, but people assessing the body size and 6-minute walk test outcomes were masked. The primary outcomes were adherence (eg, Fitbit wear and text response rate) and self-assessed acceptability of the intervention. The intervention would be considered feasible if we observed at least 80% complete follow-up and 70% adherence and satisfaction, a priori. Results From 2018 to 2020, we screened 240 patients; 53.3% (128/240) of patients were ineligible and 26.7% (64/240) declined to participate. A total of 44 patients (44/240, 18%) were randomized to the intervention (n=22) or control (n=22) groups. Of these, 57% (25/44) were women; 68% (30/44) identified as White and 25% (11/44) identified as Asian American or Pacific Islander; and 77% (34/44) had a 4-year college degree. The median age at enrollment was 54 years (IQR 45-62 years). Follow-up at 12 weeks was 91% (40/44) complete. In the intervention arm, patients wore Fitbit devices on a median of 67 out of 84 (80%) study days and responded to a median of 17 out of 27 (63%) questions sent via SMS text message. Among 19 out of 22 (86%) intervention patients who completed the feedback survey, 89% (17/19) were satisfied with the Fitbit device; 63% (12/19) were satisfied with the SMS text messages; 68% (13/19) said the SMS text messages motivated them to exercise; 74% (14/19) said the frequency of SMS text messages (1-3 days) was ideal; and 79% (15/19) said that receiving SMS text messages in the morning and evening was ideal. Conclusions This pilot study demonstrated that many people receiving chemotherapy for CRC are interested in participating in digital health physical activity interventions. Fitbit adherence was high; however, participants indicated a desire for more tailored SMS text message content. Studies with more socioeconomically diverse patients with CRC are required.

Inactivity is known to have harmful effects on the physical and mental health of older adults. This study used a randomized, parallel trial design to evaluate whether daily text prompts to practice mindfulness would have a positive impact on the time that adults aged 50 years or older spend in aerobic physical activity. The participants were recruited from a certified fitness center and divided into mindfulness and control groups. For 4 weeks, they were exposed to the experimental conditions, with or without the morning text message. In the morning message condition, the mindfulness groups received a text message with the instruction to practice audio-guided mindfulness for 10 min, and the control group received a placebo message. The participants practicing mindfulness reported significantly more weekly minutes of aerobic physical activity and higher intrinsic motivation than the control participants. Mindfulness training was effective at increasing aerobic physical activity duration and might complement physical activity programs.

Background Socially disadvantaged men are more likely to binge drink frequently and to experience high levels of alcohol-related harm. Objectives To test the effectiveness and cost-effectiveness of a text message intervention in reducing the frequency of binge drinking among disadvantaged men. Study design A four-centre, parallel-group, pragmatic, individually randomised controlled trial was conducted. Randomisation was carried out using a secure remote web-based system. It was stratified by participating centre and recruitment method and restricted using block sizes of randomly varying lengths. Setting The study was conducted in the community. Members of the public helped to develop the study methods. Participants Participants were men aged 25–44 years who had ≥ 2 episodes of binge drinking (> 8 units of alcohol in a single session) in the preceding 28 days. Men were recruited from areas of high deprivation. Interventions An empirically and theoretically based text message intervention was delivered by 112 interactive text messages over a 12-week period. The control group received an attentional control comprising 89 text messages on general health. Primary outcome measure The primary outcome measure was the proportion of men consuming > 8 units of alcohol on ≥ 3 occasions (in the previous 28 days) at 12 months post intervention. Results The recruitment target of 798 was exceeded and 825 men were randomised. Retention was high and similar in the intervention (84.9%) and control (86.5%) groups. Most men in the intervention group engaged enthusiastically with the text messages: almost all (92%) replied to text messages and over two-thirds (67%) replied more than 10 times. The intervention was estimated to have had a modest, statistically non-significant effect on the primary outcome at the 12-month follow-up [odds ratio 0.79, 95% confidence interval (CI) 0.57 to 1.08]. This corresponds to a net reduction of 5.7% in regular binge drinking. Five secondary outcomes showed small non-significant and inconsistent effects on alcohol consumption, with one suggesting a positive effect and four suggesting an adverse effect. Both the short- and the long-term cost per quality-adjusted life-year (QALY) analysis suggested that the brief intervention was dominated by a ‘do-nothing’ option. The intervention’s impacts on patterns of alcohol consumption, QALYs and downstream costs were inconsistent and uncertain. Limitations The study used an active control that, combined with the recruitment procedures and baseline assessments, could have biased the treatment effect towards the null. The measurement of alcohol consumption relied on self-reported drinking. Conclusions The trial has demonstrated that it is possible to recruit and retain large numbers of socially disadvantaged men in a research study. The text messages delivered a complex theoretically and empirically based intervention that fostered enthusiastic engagement with the key components of the behaviour change sequence. The intervention produced a modest, statistically non-significant effect on the primary outcome, with wide CIs. Further research is needed to reduce uncertainty about the treatment effect. The methods developed for this study provide a platform for the design and testing of interventions to reduce inequalities in health. Future work A future trial could reduce the uncertainty around the treatment effect of the intervention. Trial registration Current Controlled Trials ISRCTN07695192.
