Kids SIPsmartER Baseline Cross-Sectional Analyses of the Socioecological Impact Variables in Sugar Sweetened Beverage Behaviors among Rural Appalachian Adolescents

Objective: The objective of this study was to identify factors across the socioecological model (SEM) associated with adolescents’ sugar-sweetened beverage (SSB) intake. Design: This cross-sectional study surveyed adolescents using previously validated instruments. Analyses included descriptive statistics, ANOVA tests, and stepwise nonlinear regression models (i.e., two-part models) adjusted to be cluster robust. Guided by SEM, a 4-step model was used to identify factors associated with adolescent SSB intake - Step 1: demographics (i.e., age, gender), Step 2: intrapersonal [i.e., Theory of Planned Behavior (attitudes, subjective norms, perceived behavioral control, behavioral intentions), health literacy, media literacy, public health literacy], Step 3: interpersonal (i.e., caregiver’s SSB behaviors, caregiver’s SSB rules), and Step 4: environmental (i.e., home SSB availability) level variables. Setting: Eight middle schools across four rural southwest Virginia counties in Appalachia Participants: 790 7th grade students [55.4% female, 44.6% males, mean age 12 (SD=0.5) years]. Results: Mean SSB intake was 36.3 (SD=42.5) fluid ounces or 433.4 (SD=493.6) calories per day. In the final step of the regression model, seven variables significantly explained adolescent’s SSB consumption: behavioral intention (p < 0.05), affective attitude (p<0.05), perceived behavioral control (p<0.05), health literacy (p<0.001), caregiver behaviors (p<0.05), caregiver rules (p<0.05), and home availability (p<0.001). Conclusions: SSB intake among adolescents in rural Appalachia was nearly three times above national mean. Home environment was the strongest predictor of adolescent SSB intake, followed by caregiver rules, caregiver behaviors, and health literacy. Future interventions targeting these factors may provide the greatest opportunity to improve adolescent SSB intake.

Development and Pilot Testing of Text Messages to Help Reduce Sugar-Sweetened Beverage Intake Among Rural Caregivers and Adolescents: Mixed Methods Study

Background A high consumption of sugar-sweetened beverages (SSBs) poses significant health concerns, particularly for rural adults and adolescents. A manner in which the health of both caregivers and adolescents can be improved is by developing innovative strategies that target caregivers as the agents of change. Sending text messages through mobile phones has been cited as an effective way to improve behavioral outcomes, although little research has been conducted in rural areas, particularly focusing on SSB intake. Objective By targeting rural caregivers, this 2-phase study aimed to (1) understand caregivers’ perceptions and language preferences for SSB-related text messages to inform and refine message development and delivery and (2) evaluate the acceptability of text messages for SSB intake behavior change and examine short-term effects on SSB intake behavior. Methods A convergent mixed methods design was used to systematically develop and pilot-test text messages with caregivers in Southwest Virginia. In phase 1, 5 focus groups that included a card-sorting activity were conducted to explore advantages/disadvantages, language preferences (ie, tone of voice, audience, and phrase preferences), and perceived use of text messages. In phase 2, caregivers participated in a 5-week text message pilot trial that included weekly educational and personalized strategy messages and SSB intake assessments at baseline and follow-up. Before the focus groups and after completing the pilot trial, caregivers also completed a pre-post survey that assessed SSB intake, SSB home availability, and caregivers’ SSB-related practices. Caregivers also completed individual follow-up telephone interviews following the pilot trial. Results In phase 1, caregivers (N=33) reported that text messages were convenient, accessible, and easy to read. In addition, they preferred messages with empathetic and authoritative tones that provided useful strategies and stayed away from using absolute words (eg, always and never). In the phase 2 pilot trial (N=30), 87% of caregivers completed baseline and 77% completed follow-up assessment, suggesting a high utilization rate. Other ways in which caregivers reported benefiting from the text messages included sharing messages with family members and friends (80%), making mental notes (57%), and looking back at messages as reminders (50%). Caregivers reported significant improvements in home environment, parenting practices, and rulemaking around SSB (P=.003, P=.02, and P=.04, respectively). In addition, the frequency of SSB intake among caregivers and adolescents significantly decreased (P=.003 and P=.005, respectively). Conclusions Spending time in the formative phases of text message development helped understand the unique perspectives and language preferences of the target population. Furthermore, delivering an intervention through text messages has the potential to improve caregiver behaviors and reduce SSB intake among rural caregivers and adolescents. Findings from this study were used to develop a larger bank of text messages, which would be used in a future study, testing the effectiveness of a text message intervention targeting SSB intake–related caregiver behaviors.

Contextual Design Theory Applied to Wearables That Facilitate Kangaroo Care by Interviewing Mothers of Hospitalized Infants

When considering how to design medical devices considering the needs of the patient and hospital staff may seem sufficient. Hospitalized infants are patients who cannot speak or advocate for their needs; the parents and the hospital staff caring for infant patients have different roles that together are integral to an infant’s recovery. Figure 1 shows how mothers, nurses, and infants form a system of care to promote infant patient healing. In particular caregiver behaviors such as kangaroo care (KC), are dependent upon the involvement of family. KC, defined as bare skin-to-skin contact between an infant and an adult caregiver, is usually done chest-to-chest. The design of wearables for the caregivers holding the infant patient can make KC easier and be part of wearable medical device design that improves infant patient outcomes.
