Health equity in action: using community-engaged research to update an intervention promoting a healthy home food environment to Black/African American families.

PURPOSE: Describe the method for conducting community-engaged research to identify needed changes for an existing evidence-based intervention, and prepare it for implementation in a community setting within the Dan L Duncan Comprehensive Cancer Center catchment area in an effort to achieve more equitable outcomes in diet-related disease risk factors. METHODS: The intervention, Family Eats, was developed over 10 years ago. It works directly with parents of Black/African American 9-12 year old children to create a healthy home food environment to support prevention of obesity and related cancers. Data collection with community stakeholders occurred through a series of  Community Advisory Board (CAB) meetings guided by the Delphi Technique, an iterative approach for gaining group consensus on a topic. RESULTS: Key information on needed changes and potential implementation strategies were identified. Perceived level of engagement among CAB members was high overall and in terms of both quantity and quality. CONCLUSION: The Delphi Technique shows promise as a method for conducting community-engaged research that promotes engagement and identifies key information needed to adapt and implement an existing intervention in a community setting.

Exploring Factors Associated With Accelerometer Validity Among Ethnically Diverse Toddlers.

PURPOSE: Studying physical activity in toddlers using accelerometers is challenging due to noncompliance with wear time (WT) and activity log (AL) instructions. The aims of this study are to examine relationships between WT and AL completion and (1) demographic and socioeconomic variables, (2) parenting style, and (3) whether sedentary time differs by AL completion. METHODS: Secondary analysis was performed using baseline data from a community wellness program randomized controlled trial for parents with toddlers (12-35 mo). Parents had toddlers wear ActiGraph wGT3x accelerometers and completed ALs. Valid days included ≥600-minute WT. Analysis of variance and chi-square analyses were used. RESULTS: The sample (n = 50) comprised racial and ethnically diverse toddlers (mean age = 27 mo, 58% male) and parents (mean age = 31.7 y, 84% female). Twenty-eight families (56%) returned valid accelerometer data with ALs. Participants in relationships were more likely to complete ALs (P < .05). Toddler sedentary time did not differ between those with ALs and those without. CONCLUSIONS: We found varied compliance with WT instructions and AL completion. Returned AL quality was poor, presenting challenges in correctly characterizing low-activity counts to improve internal validity of WT and physical activity measures. Support from marital partners may be important for adherence to study protocols.

Feasibility of a food-based diabetes self-management education intervention for food insecure patients with type 2 diabetes: a convergent mixed methods study.

OBJECTIVE: To assess the feasibility of a food-based diabetes self-management education and support (DSMES) intervention delivered to persons with type 2 diabetes (T2DM) and food insecurity. DESIGN: This single arm pre-/post convergent mixed methods study tested the feasibility of a 3-month intervention using food boxes, recipes, DSMES and dietitian visits. Feasibility benchmarks assessed were acceptability (> 50 % participants satisfied), demand (> 50 % used program components) and implementation (75 % adherence, 80 % retention). Assessments included: self-reported food security, health-related quality of life, diabetes self-efficacy, socio-demographic and dietary intake, height, weight, and HbA1c and one in-depth interview with participants and key staff. Enrollment, recruitment and retention rates were summarised; qualitative data were analysed using structured thematic analysis (participant interviews) and key point summaries (staff interviews). Quantitative/qualitative data integration was conducted using a joint display. SETTING: Food bank and Federally Qualified Health Center in the Southwestern U.S. PARTICIPANTS: English- or Spanish-speaking adults with T2DM and food insecurity. RESULTS: In total, 247 patients with T2DM and food insecurity were recruited, seventy-one expressed interest and twenty-five consented. Twenty-one participants completed study measurements. 71 % (n 15) received six home food deliveries and ≥ 1 dietitian visit. A priori benchmarks were approached or met within each feasibility criterion - most participants found the intervention to be acceptable, used most or all intervention components, and reported some challenges within intervention implementation (e.g. timing of food deliveries). Data integration provided deeper understanding of reported intervention implementation challenges, yet high adherence to the intervention. CONCLUSIONS: The intervention was feasible. Next steps include a clinical trial to establish intervention efficacy.

A Pragmatic Guide to Qualitative Analysis for Pediatric Researchers.

OBJECTIVE: To describe four approaches to qualitative analysis in order to provide a pragmatic, application-oriented guide to their use in research focused on children and their families. METHODS: Four commonly used approaches to qualitative analysis-framework analysis, rapid qualitative analysis, content analysis, and reflexive thematic analysis-are described and compared, including their analytic strategies, tips for use, terminology, and application to a hypothetical example. RESULTS: A pragmatic guide to each method is provided as well as examples of how each analytic approach could be utilized to analyze the same dataset. CONCLUSIONS: A variety of approaches to qualitative analysis are available to both novice and experienced qualitative researchers. The approach selected from the options presented in this article will depend on numerous factors, such as the clinical problem being explored, research context, aims, objectives, research questions, and resources available such as time and funds, and the qualitative expertise of the team.

Diabetes-Related Worries and Coping Among Youth and Young Adults With Type 1 Diabetes.

OBJECTIVE: Although mood and anxiety symptoms are common in youth with type 1 diabetes (T1D), little research has described their worries across developmental stages or the strategies they use to cope with these worries. This secondary data analysis aimed to describe and characterize common T1D-related worries and coping strategies from middle childhood through young adulthood. METHODS: Twenty-three youth (9 children, 7 adolescents, and 7 young adults) completed semistructured qualitative interviews about health-related quality of life. We coded interview transcripts using thematic analysis to generate common themes of diabetes-related worries and coping strategies. RESULTS: Participants' worries fell into four major themes: Managing Blood Glucose, Self-Efficacy for Diabetes Management, Interpersonal Relationships, and Lifestyle Impact, and eight youth denied having diabetes-related worries. Coping strategies fell into the three major themes: Attempts to Change Source of Worry, Attempts to Change Reactions to Worry, and Attempts to Orient Away from the Worry. CONCLUSIONS: Youths' worries about various aspects of living with and feeling able to self-manage diabetes are important to consider across pediatric development as they can impact youths' participation in daily activities and future plans. By adolescence, youth report longer-term worries about the health and lifestyle implications of diabetes. Youths' reported coping strategies are generally consistent with existing coping frameworks, though our data suggest some possible refinements. Social support emerged as an important coping strategy for all age groups. Thus, interventions supporting youth in building and strengthening their social networks may be particularly beneficial in helping youth cope with their diabetes-related worries across development.

Vegetable parenting practices vary by feeding styles among middle class mothers of young children.

The optimal approach to feeding preschool children balances expectation setting (demandingness) with responsivity to the child (responsiveness), and ideal feeding practices use environmental structuring and covert, non-directive control strategies while maintaining responsiveness. However, research has not examined the extent to which demandingness and responsiveness in feeding style is concordant with structure, responsiveness and control (directive and non-directive) in feeding practices. We classified the feeding style of 122 parents of preschoolers as authoritative (high demandingness/high responsiveness), authoritarian (high demandingness/low responsiveness), indulgent (low demandingness/high responsiveness), or uninvolved (low demandingness/low responsiveness). Parents reported on their frequency of use of 31 vegetable parenting practices (VPPs), that were classified into the domains of structure, control and responsiveness, and subcategorized as effective (likely to obtain the desired change without increasing child obesity risk) or ineffective (unlikely or increases risk) by expert consensus. We hypothesized that parents with an authoritative feeding style would have the highest effective structure, responsiveness and control VPPs, and the authoritarian style would differ with less responsiveness VPPs. We also hypothesized that the indulgent feeding style would have low levels of structure and control VPPs and high ineffective responsiveness VPPs. As expected, we found that parents with an authoritative feeding style reported using more effective structure and responsiveness VPPs. Surprisingly, parents with an authoritarian feeding style did not have VPPs which differed from those with an authoritative feeding style, and parents with an indulgent feeding style had surprisingly high effective control VPPs. Further research into the similarities and differences between parents' overall approach to feeding and their use of feeding practices related to specific foods is warranted, which may help inform the design of more effective interventions aimed at improving child dietary quality.

Selection and use of vegetable parenting practices did not vary by parent feeding styles: Mixed methods investigation.

Parents influence their child's vegetable intake through their feeding style, i.e. the emotional tone established around feeding, and vegetable parenting practices (VPPs), i.e. the specific behaviors employed to influence their child's vegetable intake. A model of precision food parenting proposes that child healthy dietary intake could be optimized by the selection and implementation of effective food parenting practices. Parents use and learn from these complex interactions with their child, which are reflective of feeding style. Intervention research has targeted VPPs in general without a delineation of which practices were selected, which were used, or why they were selected. It is not clear how these users were influenced by feeding style, nor what the parent learned from the interaction. The current study used mixed methods wherein middle socioeconomic status parents of 3-5 year old children were categorized within feeding style groups (n = 122), asked to select two VPPs, implemented them for a week (n = 63), and qualitatively interviewed about their experience. Responsiveness VPPs were most commonly selected, primarily due to their perceived ease of implementation. Parents believed there would be long term positive outcomes, e.g. more vegetable intake from using the practices selected. Frequency of use depended in part on opportunity, e.g. food purchase parenting practices could only be employed during intermittent shopping events. Few differences were detected by parent feeding styles in the types of VPPs selected, frequency of use, or effectiveness. Food parenting interventions can encourage selection of specific VPPs to employ and do not appear to have to tailor the types of VPPs offered to parent feeding style. Research is needed with larger, socioeconomically diverse samples to assess optimal categorization into feeding styles and confirm the present results.

Later sleep timing predicts accelerated summer weight gain among elementary school children: a prospective observational study.

OBJECTIVES AND BACKGROUND: Social demands of the school-year and summer environment may affect children's sleep patterns and circadian rhythms during these periods. The current study examined differences in children's sleep and circadian-related behaviors during the school-year and summer and explored the association between sleep and circadian parameters and change in body mass index (BMI) during these time periods. METHODS: This was a prospective observational study with 119 children ages 5 to 8 years with three sequential BMI assessments: early school-year (fall), late school-year (spring), and beginning of the following school-year in Houston, Texas, USA. Sleep midpoint, sleep duration, variability of sleep midpoint, physical activity, and light exposure were estimated using wrist-worn accelerometry during the school-year (fall) and summer. To examine the effect of sleep parameters, physical activity level, and light exposure on change in BMI, growth curve modeling was conducted controlling for age, race, sex, and chronotype. RESULTS: Children's sleep midpoint shifted later by an average of 1.5 h during summer compared to the school-year. After controlling for covariates, later sleep midpoints predicted larger increases in BMI during summer, (γ = .0004, p = .03), but not during the school-year. Sleep duration, sleep midpoint variability, physical activity levels, and sedentary behavior were not associated with change in BMI during the school-year or summer. Females tended to increase their BMI at a faster rate during summer compared to males, γ = .06, p = .049. Greater amounts of outdoor light exposure (γ = -.01, p = .02) predicted smaller increases in school-year BMI. CONCLUSIONS: Obesity prevention interventions may need to target different behaviors depending on whether children are in or out of school. Promotion of outdoor time during the school-year and earlier sleep times during the summer may be effective obesity prevention strategies during these respective times.

Exploring qualities of ethnically diverse parents related to the healthy home environment of toddlers.

Parents serve as role models and household policy makers for their children's home social environment. Also, parents may influence the home physical environment through the provision of resources to support their children's dietary, activity, and sleep behaviors. Understanding the parental characteristics related to children's home environment may allow for tailoring obesity interventions to families' needs. This study aimed to explore parental qualities (general parenting styles, parent feeding practices, and parental BMI) related to healthy home food, physical activity, media and sleep environment of toddlers. A total of 50 multi-ethnic parents with toddler age children who were enrolled in a randomized pilot study of a wellness program completed the Structure and Control in Parent Feeding (SCPF) questionnaire and Comprehensive General Parenting Questionnaire (CGPQ). Parental BMI was calculated using self-reported weight and height data. The Healthy Home Survey, the Home Food Inventory, the Sleep Environment Questionnaire, and items developed for this study were standardized and summed to create home food, physical activity, screen media, and sleep environment scores; high scores reflected healthier environments. To examine the relationships between parental qualities and the home environment, Pearson's correlation test was performed. Parental BMI and overall healthy home environment were inversely associated (r = -0.306; p = 0.032). Structure in general parenting and parental feeding practice were positively correlated with the overall healthy home environment (r = 0.336; p = 0.026) and healthy home food environment (r = 0.415; p = 0.003), respectively. The coercive control general parenting was inversely related to overall healthy home environment score (r = -0.333; p = 0.022). Based on the findings from this study, parents who provide clear communication, set consistent rules, avoid pressure to control their child's behavior, and have lower BMI tend to live in a home environment that support children's health behaviors.

Beliefs of women of childbearing age on healthy sleep habits: a reasoned action approach elicitation study.

There is little information on the determinants of healthy sleep habits (HSH) among women of childbearing age (WOCBA). The objective was to identify WOCBA's beliefs on HSH based on the Reasoned Action Approach. Thirty WOCBA (18-41 years) were randomly assigned to answer questions regarding one of three HSH: avoiding screen use in bed; avoiding caffeine, alcohol and cigarettes before bedtime; and having a regular bedtime and wake up time even on weekends. A content analysis was performed independently by two experts to identify the most important beliefs using a 75% cumulative frequency of mention. Participants reported that adopting the HSH would improve sleep, avoid side effects, help them relax before bedtime and make them feel like they were missing out on things. Adopting the HSH was associated with feeling relaxed and satisfied, but also qualified as unpleasant and abnormal. WOCBA mentioned their parents, partner, siblings and children would approve/disapprove if they adopted the HSH and were the most/least likely to adopt them. Barriers were having activities in the evening and social situations. Facilitating factors were putting their electronic devices away from bed, having alternatives and a regular schedule. These results can guide the development of interventions promoting HSH among WOCBA.

Cultural adaptation of 'Healthy Dads, Healthy Kids' for Hispanic families: applying the ecological validity model.

BACKGROUND: Healthy Dads Healthy Kids (HDHK) is a unique lifestyle obesity intervention for fathers and children that demonstrated weight loss among the fathers and behavior change among fathers and children in Australia. The program is gender-tailored to specifically target fathers for weight loss and 5-12 year old children for obesity prevention. The aim of this formative study was to examine an Expert Panel's and Hispanic Family Panel's perceptions about the program and suggestions for the cultural adaptation of HDHK for Hispanic families in southwestern US. METHODS: Forty-four Hispanic participants (22 fathers, 13 mothers and 9 children) made up the Family Panel. They participated in 1-5 study contacts (focus groups, online survey, and/or interviews). The scripts and qualitative guides assessed participants' perceptions of the HDHK content and material using the Ecological Validity Model. Studies were conducted in English or Spanish, depending on the preference of the participant. Focus groups and interviews were audio-recorded, transcribed, translated, and thematically coded. Findings were reviewed with the Expert Panel who helped inform the cultural adaptation. RESULTS: 80% of parents were foreign-born, 57% spoke only Spanish at home, and 60% did not graduate from high school. Several themes emerged to inform the cultural adaptation of the program. Parents agreed with the HDHK goals and recommended the program place greater emphasis on parenting and limiting children's screen time. Some mothers and fathers wanted greater mother engagement. Weekly videos and a Facebook group emerged as favorite alternative options to engage mothers. Greater promotion of familism (inclusion and impact on whole family) was recommended for the program goals and activities. Gender roles for mothers and fathers, and differences in how fathers interact with male and female children, emerged and should be considered in program activities. Several barriers to father engagement surfaced, including lack of time due to work schedules, physically demanding jobs, concerns of caring for children without mother, fathers' current fitness/weight, and lack of knowledge of how to eat more healthfully. The reading level of the HDHK materials was too high for some parents. CONCLUSION: Findings from these formative qualitative studies informed the cultural adaptation of HDHK for Hispanic families, to account for literacy level, cultural values, and barriers to participation and engagement.

Assessing Health-Related Quality of Life in Children and Adolescents with Diabetes: Development and Psychometrics of the Type 1 Diabetes and Life (T1DAL) Measures.

OBJECTIVE: To develop and validate new measures of diabetes-specific health-related quality of life (HRQOL) for people with type 1 diabetes (T1D) that are brief, developmentally appropriate, and usable in clinical research and care. Here we report on the phases of developing and validating the self-report Type 1 Diabetes and Life (T1DAL) measures for children (age 8-11) and adolescents (age 12-17). METHODS: Measure development included qualitative interviews with youth and parents (n = 16 dyads) followed by piloting draft measures and conducting cognitive debriefing with youth (n = 9) to refine the measures. To evaluate the psychometric properties, children (n = 194) and adolescents (n = 257) at three T1D Exchange Clinic Network sites completed the age-appropriate T1DAL measure and previously validated questionnaires measuring related constructs. Using psychometric data, the investigators reduced the length of each T1DAL measure to 21 and 23 items, respectively, and conducted a final round of cognitive debriefing with six children and adolescents. RESULTS: The T1DAL measures for children and adolescents demonstrated good internal consistency (α = 0.84 and 0.89, respectively) and test-retest reliability (r = 0.78 and 0.80, respectively). Significant correlations between the T1DAL scores and measures of general quality of life, generic and diabetes-specific HRQOL, diabetes burden, and diabetes strengths demonstrated construct validity. Correlations with measures of self-management (child and adolescent) and glycemic control (adolescent only) demonstrated criterion validity. Factor analyses indicated four developmentally specific subscales per measure. Participants reported satisfaction with the measures. CONCLUSIONS: The new T1DAL measures for children and adolescents with T1D are reliable, valid, and suitable for use in care settings and clinical research.

Food Sources of Shortfall Nutrients Among US Adolescents: National Health and Nutrition Examination Survey (NHANES) 2011-2014.

To identify food sources of shortfall nutrients consumed by adolescents (n = 3156), data from the National Health and Nutrition Examination Survey (NHANES) (2011-2014) were used. Some of the food groups commonly consumed by adolescents made a significant contribution to shortfall nutrient intakes in the diet. Many food sources that provided significant amounts of shortfall nutrients were from foods that also provided nutrients to limit. Awareness of nutrient intakes and food sources is essential to establish dietary guidance in a practical context. Efforts to continue monitoring the food sources of nutrients consumed by adolescents will be important to improve the current knowledge on this topic of research.

Potential circadian and circannual rhythm contributions to the obesity epidemic in elementary school age children.

Children gain weight at an accelerated rate during summer, contributing to increases in the prevalence of overweight and obesity in elementary-school children (i.e., approximately 5 to 11 years old in the US). Int J Behav Nutr Phys Act 14:100, 2017 explained these changes with the "Structured Days Hypothesis" suggesting that environmental changes in structure between the school year and the summer months result in behavioral changes that ultimately lead to accelerated weight gain. The present article explores an alternative explanation, the circadian clock, including the effects of circannual changes and social demands (i.e., social timing resulting from societal demands such as school or work schedules), and implications for seasonal patterns of weight gain. We provide a model for understanding the role circadian and circannual rhythms may play in the development of child obesity, a framework for examining the intersection of behavioral and biological causes of obesity, and encouragement for future research into bio-behavioral causes of obesity in children.

Top food sources of percentage of energy, nutrients to limit and total gram amount consumed among US adolescents: National Health and Nutrition Examination Survey 2011-2014.

OBJECTIVE: To identify most commonly consumed foods by adolescents contributing to percentage of total energy, added sugars, SFA, Na and total gram intake per day. DESIGN: Data from the National Health and Nutrition Examination Survey (NHANES) 2011-2014. SETTING: NHANES is a cross-sectional study nationally representative of the US population.ParticipantsOne 24 h dietary recall was used to assess dietary intake of 3156 adolescents aged 10-19 years. What We Eat in America food category classification system was used for all foods consumed. Food sources of energy, added sugars, SFA, Na and total gram amount consumed were sample-weighted and ranked based on percentage contribution to intake of total amount. RESULTS: Three-highest ranked food subgroup sources of total energy consumed were: sugar-sweetened beverages (SSB; 7·8 %); sweet bakery products (6·9 %); mixed dishes - pizza (6·6 %). Highest ranked food sources of total gram amount consumed were: plain water (33·1 %); SSB (15·8 %); milk (7·2 %). Three highest ranked food sources of total Na were: mixed dishes - pizza (8·7 %); mixed dishes - Mexican (6·7 %); cured meats/poultry (6·6 %). Three highest ranked food sources of SFA were: mixed dishes - pizza (9·1 %); sweet bakery products (8·3 %); mixed dishes - Mexican (7·9 %). Three highest ranked food sources of added sugars were: SSB (42·1 %); sweet bakery products (12·1 %); coffee and tea (7·6 %). CONCLUSIONS: Identifying current food sources of percentage energy, nutrients to limit and total gram amount consumed among US adolescents is critical for designing strategies to help them meet nutrient recommendations within energy needs.

Using Relational Agents to Promote Family Communication Around Type 1 Diabetes Self-Management in the Diabetes Family Teamwork Online Intervention: Longitudinal Pilot Study.

BACKGROUND: Family conflict can reduce adolescent adherence to type 1 diabetes management tasks. The Family Teamwork in-person intervention was shown to be efficacious in reducing conflict and low adherence to diabetes-related tasks. Its reach and potential impact, however, were limited by the need to deliver the intervention sessions in person. Relational agents (ie, computerized versions of humans) have been shown to appeal to diverse audiences and may be an acceptable replacement for a human in technology-based behavior change interventions. OBJECTIVE: The purpose of this paper is to present the results of a pilot study assessing feasibility and acceptability of Diabetes Family Teamwork Online, an adapted version of the Family Teamwork intervention, delivered over the internet and guided by a relational agent. METHODS: Parent-adolescent dyads were recruited through a diabetes care clinic at a large tertiary care hospital in the southwestern United States. A one-group design, with assessments at baseline, immediate postintervention, and 3 months later, was used to assess feasibility. A priori feasibility criteria included an assessment of recruitment, completion, attrition, program satisfaction, therapeutic alliance, attitudes toward the relational agent, and data collection. The institutional review board at Baylor College of Medicine approved the protocol (H-37245). RESULTS: Twenty-seven adolescents aged 10 to 15 years with type 1 diabetes and their parents were enrolled. Criteria used to assess feasibility were (1) recruitment goals were met (n=20), (2) families completed ≥75% of the modules, (3) attrition rate was ≤10%, (4) program satisfaction was high (≥80% of families), (5) therapeutic alliance was high (average score of ≥60/84), (6) families expressed positive attitudes toward the relational agent (average item score of ≥5 on ≥4 items), (7) ≥80% of data were collected at post 1 and post 2, and (8) few technical issues (≤10%) occurred during intervention delivery. All feasibility criteria were met. Qualitative data confirmed that adolescents and parents had positive reactions to both the content and approach. CONCLUSIONS: The Diabetes Family Teamwork Online intervention proved to be a feasible and acceptable method for enhancing communication around diabetes management tasks in families with an adolescent who has type 1 diabetes.

"Healthy Habits, Healthy Girls-Brazil": an obesity prevention program with added focus on eating disorders.

PURPOSE: To evaluate the immediate post-intervention and 6-month post-intervention effects of a Brazilian school-based randomized controlled trial for girls targeting shared risk factors for obesity and disordered eating. METHODS: Total of 253 girls, mean of 15.6 (0.05) years from 1st to 3rd grades of high school participated in this 6-month school-based cluster randomized controlled trial. "Healthy Habits, Healthy Girls-Brazil (H3G-Brazil)", originally developed in Australia, emphasized 10 key nutrition and physical activity (PA) messages delivered over 6 months. Disordered eating prevention procedures, i.e., prevention of weight-teasing, body satisfaction, and unhealthy weight control behavior, were added to the intervention. Body dissatisfaction, unhealthy weight control behaviors and social cognitive-related diet, and physical activity variables were assessed at baseline, immediate post-intervention, and 6-month post-intervention. Intervention effects were determined by one-way analysis of covariance or logistic regression, after checking for the clustering effects of school. The control group did not receive intervention prior to follow-up assessment. A conservative significance level was set at p < 0.01. RESULTS: Beneficial effects were detected for PA social support (F = 6.005, p = 0.01), and healthy eating strategies (F = 6.08, p = 0.01) immediate post-intervention; and healthy eating social support (F = 14.731, p = 0.00) and healthy eating strategies (F = 5.812, p = 0.01) at 6-month post-intervention. Intervention group was more likely to report unhealthy weight control behaviors (OR = 1.92, 95% CI 1.15-3.21, p = 0.01) at 6-month post-intervention. No other significant immediate or 6-month post effects were detected. CONCLUSION: H3G-Brazil demonstrated positive 6-month effects on some social cognitive variables but an adverse effect on unhealthy weight control behaviors. Thus, this study was not able to achieve synergy by combining obesity and disordered eating prevention procedures in an intervention among low-income girls in Brazil. TRIAL REGISTRATION: Level I: cluster randomized controlled trial.

The effectiveness of asking behaviors among 9-11 year-old children in increasing home availability and children's intake of fruit and vegetables: results from the Squire's Quest II self-regulation game intervention.

BACKGROUND: Home environment has an important influence on children's fruit and vegetable (FV) consumption, but children may in turn also impact their home FV environment, e.g. by asking for FV. The Squire's Quest II serious game intervention aimed to increase asking behaviors to improve home FV availability and children's FV intake. This study's aims were to assess: 1) did asking behaviors at baseline predict home FV availability at baseline (T0) (RQ1); 2) were asking behaviors and home FV availability influenced by the intervention (RQ2); 3) did increases in asking behaviors predict increased home FV availability (RQ3); and 4) did increases in asking behaviors and increases in home FV availability mediate increases in FV intake among children (RQ4)? METHODS: This is a secondary analysis of a study using a randomized controlled trial, with 4 groups (each n = 100 child-parent dyads). All groups were analyzed together for this paper since groups did not vary on components relevant to our analysis. All children and parents (n = 400 dyads) received a self-regulation serious game intervention and parent material. The intervention ran for three months. Measurements were taken at baseline, immediately after intervention and at 3-month follow-up. Asking behavior and home FV availability were measured using questionnaires; child FV intake was measured using 24-h dietary recalls. ANCOVA methods (research question 1), linear mixed-effect models (research question 2), and Structural Equation Modeling (research questions 3 and 4) were used. RESULTS: Baseline child asking behaviors predicted baseline home FV availability. The intervention increased child asking behaviors and home FV availability. Increases in child asking behaviors, however, did not predict increased home FV availability. Increased child asking behaviors and home FV availability also did not mediate the increases in child FV intake. CONCLUSIONS: Children influence their home FV environment through their asking behaviors, which can be enhanced via a serious game intervention. The obtained increases in asking behavior were, however, insufficient to affect home FV availability or intake. Other factors, such as child preferences, sample characteristics, intervention duration and parental direct involvement may play a role and warrant examination in future research.

Places where preschoolers are (in)active: an observational study on Latino preschoolers and their parents using objective measures.

BACKGROUND: To combat the disproportionately higher risk of childhood obesity in Latino preschool-aged children, multilevel interventions targeting physical (in) activity are needed. These require the identification of environmental and psychosocial determinants of physical (in) activity for this ethnic group. The objectives were to examine differences in objectively-measured physical activity and sedentary behavior across objectively-determined types of locations in Latino preschool-aged children; and determine whether the differences in physical activity by location were greater in children of parents with higher neighborhood-safety perceptions and physical activity-supportive parenting practices. METHODS: An observational field study was conducted in Houston (Texas, USA) from August 2011 to April 2012. A purposive sample of Latino children aged 3-5 years and one of their parents (n = 84) were recruited from Census block groups in Houston (Texas) stratified by objectively-assessed high vs. low traffic and crime safety. Seventy-three children provided valid data. Time spent outdoors/indoors tagged with geographic locations was coded into location types based on objective data collected using Global Positioning Systems units that children wore >8 hr/day for a week. Physical activity parenting practices, perceived neighborhood-safety, and demographics were reported by parents. Time spent in sedentary behavior and moderate-to-vigorous physical activity was measured based on objective data collected using accelerometers (motion sensors) that children wore >8 hr/day for a week. RESULTS: The odds of children engaging in moderate-to-vigorous physical activity were 43% higher when outdoors than indoors (95% confidence interval: 1.30, 1.58), and the odds of being sedentary were 14% lower when outdoors compared to indoors (95% confidence intervals: 0.81, 0.91). This difference depended on parental neighborhood-safety perceptions and parenting practices. Children were most active in parks/playgrounds (30% of the time spent in moderate-to-vigorous physical activity) and least active in childcare/school settings (8% of the time spent in moderate-to-vigorous physical activity). CONCLUSIONS: Objectively-assessed time spent in specific locations is correlated with physical activity and sedentary behavior in Latino preschoolers. Interventions and policies should identify ways to engage Latino preschool-aged children in more physical activity and less sedentary behavior while in childcare, and encourage parents to spend more time with their young children in parks/playgrounds and other safe outdoor places.

Is Participatory Design Associated with the Effectiveness of Serious Digital Games for Healthy Lifestyle Promotion? A Meta-Analysis.

BACKGROUND: Serious digital games can be effective at changing healthy lifestyles, but large differences in their effectiveness exist. The extent of user involvement in game design may contribute to game effectiveness by creating a better fit with user preferences. Participatory design (PD), which represents active user involvement as informant (ie, users are asked for input and feedback) or codesigner (ie, users as equal partners in the design) early on and throughout the game development, may be associated with higher game effectiveness, as opposed to no user involvement or limited user involvement. OBJECTIVE: This paper reports the results of a meta-analysis examining the moderating role of PD in the effectiveness of serious digital games for healthy lifestyle promotion. METHODS: Four databases were searched for peer-reviewed papers in English that were published or in press before October 2014, using a (group-) randomized controlled trial design. Effectiveness data were derived from another meta-analysis assessing the role of behavior change techniques and game features in serious game effectiveness. RESULTS: A total of 58 games evaluated in 61 studies were included. As previously reported, serious digital games had positive effects on healthy lifestyles and their determinants. Unexpectedly, PD (g=0.075, 95% CI 0.017 to 0.133) throughout game development was related to lower game effectiveness on behavior (Q=6.74, P<.05) than when users were only involved as testers (g=0.520, 95% CI 0.150 to 0.890, P<.01). Games developed with PD (g=0.171, 95% CI 0.061 to 0.281, P<.01) were also related to lower game effectiveness on self-efficacy (Q=7.83, P<.05) than when users were not involved in game design (g=0.384, 95% CI 0.283 to 0.485, P<.001). Some differences were noted depending on age group, publication year of the study, and on the specific role in PD (ie, informant or codesigner), and depending on the game design element. Games developed with PD were more effective in changing behavioral determinants when they included users in design elements on game dynamics (beta=.215, 95% CI .075 to .356, P<.01) and, more specifically, as an informant (beta=.235, 95% CI .079 to .329, P<.01). Involving users as informants in PD to create game levels was also related to higher game effectiveness (Q=7.02, P<.01). Codesign was related to higher effectiveness when used to create the game challenge (Q=11.23, P<.01), but to lower game effectiveness when used to create characters (Q=4.36, P<.05) and the game world (Q=3.99, P<.05). CONCLUSIONS: The findings do not support higher effectiveness of games developed with PD. However, significant differences existed among PD games. More support was found for informant roles than for codesign roles. When PD was applied to game dynamics, levels, and game challenge, this was associated with higher effectiveness than when it was applied to game aesthetics. Since user involvement may have an important influence on reach, adoption, and implementation of the intervention, further research and design efforts are needed to enhance effectiveness of serious games developed with PD.
