Abstract Objectives Ecological momentary assessment (EMA) is an innovative tool being used in the obesity field to capture real-time information about people's health. A recent systematic review regarding the use of EMA to assess dietary intake and physical activity in youth found the need for standardized reporting of EMA measures and methods. This presentation will discuss EMA methods used in the NIH-funded Family Matters study, including survey design, registration/technology, EMA protocols, implementation, and lessons learned for future EMA studies. Methods Family Matters is an incremental, two-phased (Phase I = 150 participants; Phase II = 627 participants), mixed-methods study conducted with a racially/ethnically diverse and immigrant/refugee sample from largely low-income households. Across two phases, the Family Matters research team designed and administered EMA surveys to parents of 5–9 year olds to measure momentary factors of importance to child weight and weight-related behaviors including parent feeding practices, child eating behaviors, meal preparation, and foods served at family meals. Results EMA data allowed for many cutting-edge research questions to be addressed, innovative analyses to be run, and methodological approaches to be advanced. Many diet-related topics were investigated, including 1) the investigation of both within-and across-day relationships between transient and chronic stress and parent feeding practices; 2) parental stress and mood earlier in the day and its association with parent feeding practices later in the day; and 3) family meal characteristics by meal type and day of the week. Additionally, concordance between diet-related EMA measures and objectively collected 24-hour dietary recalls was examined. Family Matters EMA diet-related measures will be presented and related results discussed. Conclusions This presentation will be valuable for researchers interested in using EMA for collecting obesity-related measures, such as dietary intake, physical activity, parent feeding practices, and stress/mood.

AbstractObjective:This study is a secondary data analysis that examines the association between parent modelling of dietary intake and physical activity and the same child behaviours among different races/ethnicities using innovative, rigorous and objective measures.Design:Ecological momentary assessment surveys were sent to parents to assess whether their child had seen them exercise or consume food. Dietary recall data and accelerometry were used to determine dietary intake and physical activity behaviours of children.Setting:Participants were randomly selected from primary care clinics, serving low-income and racially/ethnically diverse families in Minnesota, USA.Participants:Participants were families with children aged 5–7 years old who lived with parents 50 % of the time and shared at least one meal together.Results:A 10 percentage point higher prevalence in parent modelling of fruit and vegetable intake was associated with 0·12 higher serving intake of those same foods in children. The prevalence of parent modelling of eating energy dense foods (10 % prevalence units) was associated with 0·09 higher serving intake of sugar-sweetened beverages. Furthermore, accelerometry-measured parent sedentary hours was strongly correlated with child sedentary time (0·37 child sedentary hours per parent sedentary hours). An exploratory interaction analysis did not reveal any statistical evidence that these relationships depended on the child’s race/ethnic background.Conclusions:Interventions that increase parent modelling of healthy eating and minimise modelling of energy dense foods may have favourable effects on child dietary quality. Additionally, future research is needed to clarify the associations of parent modelling of physical activity and children’s physical activity levels.

Abstract Background Mothers of young children from low-income communities may be vulnerable to barriers associated with low physical activity. The purpose of this study was to examine associations between home environment factors and maternal physical activity among mothers of toddlers. Methods Mothers of toddlers (n = 200) recruited from low-income communities simultaneously wore an ankle-placed accelerometer and were given a personal digital assistant for ecological momentary assessment. Mothers received randomly prompted questions about their current environment, activity, and social setting several times a day over eight consecutive days. Data were analyzed using linear mixed-effects regression models with random intercepts; within-group and between-group relations between physical activity and environment factors were disaggregated. Results Within-group relations included higher physical activity counts for specific mothers with television off versus on (95% CI = 130.45, 199.17), children absent versus present (95% CI = 82.00, 3.43), engaging with a child versus not (95% CI = 52.66, 127.63), and outside versus inside location (95% CI = 277.74, 392.67). Between-group relations included higher physical activity on average when other adults were absent versus present (95% CI = − 282.63, − 46.95). Recruitment site (urban vs. semi-urban) significantly moderated the within-group relation between being outside versus inside and activity count (β = − 243.12, 95% CI = − 358.74, − 127.47), and showed stronger relations among urban mothers (β = 440.33, 95% CI = 358.41, 522.25), than semi-urban (β = 190.37, 95% CI = 109.64, 271.11). Maternal body weight significantly moderated the within-group relation between being located outside versus inside the home and activity count (β for interaction = − 188.67, 95% CI = − 308.95, − 68.39), with a stronger relation among mothers with normal weight (β = 451.62, 95% CI = 345.51, 557.73), than mothers with overweight/obesity (β = 271.95, 95% CI = 204.26, 339.64). Conclusions This study highlights home environmental factors, including screen time, the presence of others (adults and children), and location (i.e., outside versus inside) that may relate to maternal physical activity behaviors. Understanding factors associated with physical activity could reduce physical activity disparities. Trial registry ClinicalTrials. NCT02615158, April 2006

BACKGROUND Ecological momentary assessment (EMA) is an innovative tool to capture in-the-moment health behaviors as people go about their regular lives. EMA is an ideal tool to measure weight-related behaviors, such as parent feeding practices, stress, and dietary intake, as these occur on a daily basis and vary across time and context. A recent systematic review recommended standardized reporting of EMA design for studies that address weight-related behaviors. OBJECTIVE This manuscript describes in detail the EMA design of the Family Matters study. METHODS Family Matters is an incremental, two-phased, mixed-methods study conducted with a racially/ethnically diverse and immigrant/refugee sample from largely low-income households designed to examine the risk and protective factors for childhood obesity in the home environment. The Family Matters study intentionally recruited White, Black, Hmong, Latino, Native American, and Somali parents with young children. Parents in Phase I of the study completed eight days of EMA on their smart phones, which included 1) signal-contingent surveys (e.g., asking about the parent’s stress at the time of the survey); 2) event-contingent surveys (e.g., descriptions of the meal the child ate); 3) end-of-day surveys (e.g., overall assessment of the child’s day).cribes in detail the EMA design of the Family Matters study. RESULTS A detailed description of EMA strategies, protocols, and methods used in Phase I of the Family Matters study is provided. Compliance with EMA surveys and participant time spent completing EMA surveys is presented, stratified by race/ethnicity. Additionally, lessons learned while conducting Phase I EMA are shared to document how EMA methods were improved and expanded upon for Phase II. CONCLUSIONS Results from this study provide an important next step in identifying best practices for EMA use in assessing weight-related behaviors in the home environment.

Abstract Background and Objectives Smartphone-based ecological momentary assessment (EMA) methods can provide novel insights into modeling and predicting activity-related behaviors, yet many racial and ethnic minority groups report barriers to participating in mobile health research. We aim to (1) report on strategies used to successfully recruit and retain minority older adults in a smartphone-based physical activity and sedentary behavior EMA study and (2) report on participants’ perceptions of study acceptability. Research Design and Methods Researchers partnered with trusted individuals and community organizations serving older adults to facilitate recruitment for an 8-day EMA study of minority older adults’ physical activity and sedentary behavior. Additional strategies such as having experienced, culturally competent team members and available technical support were employed to further recruitment and retention efforts. A post study questionnaire assessed participants’ perceptions of study acceptability. Results In total, 123 minority older adults were recruited; 102 met inclusion criteria, 91 completed the study, and 89 completed the post-study questionnaire. The sample consisted of predominantly low-income African American women with an average age of 70 years. Responses to open-ended questions revealed the most enjoyable aspects of study participation were the ability to learn more about themselves, contribute to science and/or their community, engage in a new activity, and receive financial compensation. Participants reported the least enjoyable aspects of the study included the frequency of EMA questionnaires, apprehension of missing EMA questionnaires, carrying the smartphone, and difficulty wearing the accelerometer. Most participants (97%) expressed interest in being contacted for future studies. Discussion and Implications Low-income, older African Americans reported positive perceptions of a smartphone-based EMA study of physical activity and sedentary behavior. Findings suggest that applying demonstrated strategies to engage this population in technology-based health research can enhance recruitment and retention efforts; however, it is unclear which strategies are most effective in reducing participation barriers.

Momentary feelings of pleasure and purpose can be sources of intrinsic motivation, but momentary purpose is rarely studied. Activities, contexts, and feelings of retired/semiretired adults (n = 67, aged 50–78 years) were captured using ecological momentary assessment. Participants provided 2,065 valid responses to six daily smartphone surveys for 7 days. Physical activity was measured by waist-worn ActiGraph accelerometer. Pleasure (measured by affective happiness) and purpose outcomes were regressed on activities, context, and potential confounding variables. Interactions between activities and contexts were explored. Participants were highly active: 98.5% met physical activity guidelines. Sedentary activities were negatively associated with sense of purpose, especially when indoors. However, social sedentary activities were positively associated with feelings of happiness. Active, social outdoor activities were positively associated with both outcomes. Less sedentary participants experienced greater happiness and purpose during all their activities. Context matters: active, social, and outdoor activities seem to be more appealing to older adults.
