Momentary Factors and Study Characteristics Associated With Participant Burden and Protocol Adherence: Ecological Momentary Assessment.

BACKGROUND: Ecological momentary assessment (EMA) has become a popular mobile health study design to understand the lived experiences of dynamic environments. The numerous study design choices available to EMA researchers, however, may quickly increase participant burden and could affect overall adherence, which could limit the usability of the collected data. OBJECTIVE: This study quantifies what study design, participant attributes, and momentary factors may affect self-reported burden and adherence. METHODS: The EMA from the Phase 1 Family Matters Study (n=150 adult Black, Hmong, Latino or Latina, Native American, Somali, and White caregivers; n=1392 observation days) was examined to understand how participant self-reported survey burden was related to both design and momentary antecedents of adherence. The daily burden was measured by the question "Overall, how difficult was it for you to fill out the surveys today?" on a 5-item Likert scale (0=not at all and 4=extremely). Daily protocol adherence was defined as completing at least 2 signal-contingent surveys, 1 event-contingent survey, and 1 end-of-day survey each. Stress and mood were measured earlier in the day, sociodemographic and psychosocial characteristics were reported using a comprehensive cross-sectional survey, and EMA timestamps for weekends and weekdays were used to parameterize time-series models to evaluate prospective correlates of end-of-day study burden. RESULTS: The burden was low at 1.2 (SD 1.14) indicating "a little" burden on average. Participants with elevated previous 30-day chronic stress levels (mean burden difference: 0.8; P=.04), 1 in 5 more immigrant households (P=.02), and the language primarily spoken in the home (P=.04; 3 in 20 more non-English-speaking households) were found to be population attributes of elevated moderate-high burden. Current and 1-day lagged nonadherence were correlated with elevated 0.39 and 0.36 burdens, respectively (P=.001), and the association decayed by the second day (ß=0.08; P=.47). Unit increases in momentary antecedents, including daily depressed mood (P=.002) and across-day change in stress (P=.008), were positively associated with 0.15 and 0.07 higher end-of-day burdens after controlling for current-day adherence. CONCLUSIONS: The 8-day EMA implementation appeared to capture momentary sources of stress and depressed mood without substantial burden to a racially or ethnically diverse and immigrant or refugee sample of parents. Attention to sociodemographic attributes (eg, EMA in the primary language of the caregiver) was important for minimizing participant burden and improving data quality. Momentary stress and depressed mood were strong determinants of participant-experienced EMA burden and may affect adherence to mobile health study protocols. There were no strong indicators of EMA design attributes that created a persistent burden for caregivers. EMA stands to be an important observational design to address dynamic public health challenges related to human-environment interactions when the design is carefully tailored to the study population and to study research objectives.

Understanding the relationships between acculturation, food insecurity, and food parenting practices among socioeconomically/racially diverse parents.

Research suggests that acculturation and food insecurity are factors that are separately associated with the use of specific food parenting practices among United States (US) families. Certain food parenting practices, such as coercive control and unstructured food parenting practices, are related to negative health consequences in children, such as disordered eating behaviors. The current study aimed to explore associations between acculturation strategies and food parenting practices in a sample of 577 Latinx, Hmong, Somali/Ethiopian, and Multiracial families. A secondary objective was to understand whether food security status significantly modified the relationships between acculturation strategies and food parenting practices. Results showed that acculturation strategies were significantly related to food parenting practices, and patterns in these relationships differed across race and ethnicity. Further, food security status significantly modified the relationship between acculturation strategies and food parenting practices for Latinx, Hmong, and Somali/Ethiopian families, but not for Multiracial families. These results point to the complex relationships among acculturation strategies, food security status, and food parenting practices in immigrant populations in the US. Longitudinal studies exploring the temporal relationships between acculturation strategies, food security status, and food parenting practices would help tease apart how food parenting practices may evolve upon migrating to the US.

Using enrollment records to evaluate self-reports of monthly coverage in the redesigned current population survey health insurance module.

OBJECTIVE: To evaluate the veracity of self-reports of month-level health insurance coverage in the Current Population Survey Annual Social and Economic Supplement (CPS). DATA SOURCES AND STUDY SETTING: The CHIME (Comparing Health Insurance Measurement Error) study used health insurance enrollment records from a large regional Midwest insurer as sample for primary data collection in spring 2015. STUDY DESIGN: A sample of individuals enrolled in a range of public and private coverage types (including Medicaid and marketplace) was administered the CPS health insurance module, which included questions about month-level coverage, by type, over a 17-18-month time span. Survey data was then matched to enrollment records covering that same time frame, and concordance between the records and self-reports was assessed. DATA COLLECTION/EXTRACTION METHODS: Sample was drawn by the insurer's informatics specialists and Census Bureau interviewers conducted the survey. Following data collection, updated enrollment records were matched to the survey data to produce a person-level file of coverage by type at the month-level. PRINCIPAL FINDINGS: For 91% of the overall sample, coverage status and type were reported accurately for at least 75% of observed months. Results varied somewhat by stability of coverage. Among those who were continuously covered throughout the 17-18 month observation period (which comprised 64% of the overall sample), that level of reporting accuracy was observed for 94% of the sample; for those who had censored spells (34% of the overall sample), the figure was 87%; and among those with gaps and/or changes according to the records (2% of the overall sample), for 82% of the group at least 75% of months were reported accurately. CONCLUSIONS: Findings suggest that reporting accuracy of month-level coverage in the CPS is high and that the survey could become a valuable new data source for studying the dynamics of coverage, including the Medicaid unwinding.

Real-time predictors of food parenting practices and child eating behaviors in racially/ethnically diverse families.

BACKGROUND: Prior research has shown associations between controlling food parenting practices (e.g., pressure-to-eat, restriction) and factors that increase risk for cardiovascular disease in children (e.g., low diet quality, obesity). This study aimed to examine associations between real-time parental stress and depressed mood, food parenting practices, and child eating behaviors in a longitudinal cohort study. METHODS: Children ages 5-9 years and their families (n = 631) from six racial/ethnic groups (African American, Hispanic, Hmong, Native American, Somali/Ethiopian, White) were recruited for this study through primary care clinics in a large metromolitan area in the US (Minneapolis/St. Paul, MN) in 2016-2019. Ecological momentary assessment was carried out over seven days with parents at two time points, 18 months apart. Adjusted associations between morning stress and depressed mood of parents on food parenting practices and child eating behaviors at the evening meal were examined. Interactions tested whether food security, race/ethnicity and child sex moderated associations. RESULTS: High levels of parental stress and depressed mood experienced earlier in the day were associated with controlling food parenting practices and child food fussiness at dinner the same night. Results were dependent on food security status, race/ethnicity, and child sex. CONCLUSIONS: Health care professionals may want to consider, or continue, screening parents for stress, depression, and food insecurity during well-child visits and discuss the influence these factors may have on food parenting practices and child eating behaviors. Future research should use real-time interventions such as ecological momentary intervention to reduce parental stress and depressed mood to promote healthy food parenting practices and child eating behaviors.

Household food insecurity is associated with greater prevalence and 18-month incidence of a range of disordered eating behaviors in a racially and ethnically diverse sample of parents.

This study examined cross-sectional and longitudinal associations between household food insecurity (FI) and a range of disordered eating behaviors (DEBs) and explored whether associations differ by Supplemental Nutrition Assistance Program (SNAP)/Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) participation. Data came from 1120 racially/ethnically diverse parents (Mage = 35.7 ± 7.8 years at baseline) in the Family Matters longitudinal cohort study. Parents reported on household FI and SNAP/WIC participation at baseline, and on past-year restrictive weight-control behaviors (WCBs; e.g., fasting), compensatory WCBs (e.g., self-induced vomiting), and binge eating at baseline and 18-month follow-up. Sociodemographics-adjusted modified Poisson regressions examined baseline household FI in relation to baseline prevalence and 18-month incidence (i.e., new onset) of each type of DEB. Moderation by SNAP/WIC participation was also tested. Household FI affected 29.6 % of participants and was associated with significantly greater baseline prevalence (prevalence ratios ranging from 1.38 to 2.69) and 18-month incidence (risk ratios ranging from 1.63 to 2.93) of each type of DEB examined. The association between household FI and incident compensatory WCBs differed significantly by SNAP/WIC participation, such that household FI significantly predicted new-onset compensatory WCBs at follow-up only among those participating in SNAP/WIC. Results from this study are the first, to our knowledge, to demonstrate that FI is longitudinally associated with restrictive and compensatory DEBs, thereby highlighting FI as a risk factor not only for binge eating, but for a range of DEBs. These findings emphasize the importance of screening for FI in clinical settings and the need to address structural barriers to food security.

A three-arm randomized controlled trial using ecological momentary intervention, community health workers, and video feedback at family meals to improve child cardiovascular health: the Family Matters study design.

BACKGROUND: Numerous observational studies show associations between family meal frequency and markers of child cardiovascular health including healthful diet quality and lower weight status. Some studies also show the "quality" of family meals, including dietary quality of the food served and the interpersonal atmosphere during meals, is associated with markers of child cardiovascular health. Additionally, prior intervention research indicates that immediate feedback on health behaviors (e.g., ecological momentary intervention (EMI), video feedback) increases the likelihood of behavior change. However, limited studies have tested the combination of these components in a rigorous clinical trial. The main aim of this paper is to describe the Family Matters study design, data collection protocols, measures, intervention components, process evaluation, and analysis plan. METHODS/DESIGN: The Family Matters intervention utilizes state-of-the-art intervention methods including EMI, video feedback, and home visiting by Community Health Workers (CHWs) to examine whether increasing the quantity (i.e., frequency) and quality of family meals (i.e., diet quality, interpersonal atmosphere) improves child cardiovascular health. Family Matters is an individual randomized controlled trial that tests combinations of the above factors across three study Arms: (1) EMI; (2) EMI + Virtual Home Visiting with CHW + Video Feedback; and (3) EMI + Hybrid Home Visiting with CHW + Video Feedback. The intervention will be carried out across 6 months with children ages 5-10 (n = 525) with increased risk for cardiovascular disease (i.e., BMI ≥ 75%ile) from low income and racially/ethnically diverse households and their families. Data collection will occur at baseline, post-intervention, and 6 months post-intervention. Primary outcomes include child weight, diet quality, and neck circumference. DISCUSSION: This study will be the first to our knowledge to use multiple innovative methods simultaneously including ecological momentary intervention, video feedback, and home visiting with CHWs within the novel intervention context of family meals to evaluate which combination of intervention components are most effective in improving child cardiovascular health. The Family Matters intervention has high potential public health impact as it aims to change clinical practice by creating a new model of care for child cardiovascular health in primary care. TRIAL REGISTRATION: This trial is registered in clinicaltrials.gov (Trial ID: NCT02669797). Date recorded 5/02/22.

Exploring the associations between neighbourhood food environment, household food insecurity and child weight-related outcomes in socio-economically and racially/ethnically diverse families.

OBJECTIVE: To examine associations among neighbourhood food environments (NFE), household food insecurity (HFI) and child's weight-related outcomes in a racially/ethnically diverse sample of US-born and immigrant/refugee families. DESIGN: This cross-sectional, observational study involving individual and geographic-level data used multilevel models to estimate associations between neighbourhood food environment and child outcomes. Interactions between HFI and NFE were employed to determine whether HFI moderated the association between NFE and child outcomes and whether the associations differed for US-born v. immigrant/refugee groups. SETTING: The sample resided in 367 census tracts in the Minneapolis/St. Paul, MN metropolitan area, and the data were collected in 2016-2019. PARTICIPANTS: The sample was from the Family Matters study of families (n 1296) with children from six racial/ethnic and immigrant/refugee groups (African American, Latino, Hmong, Native American, Somali/Ethiopian and White). RESULTS: Living in a neighbourhood with low perceived access to affordable fresh fruits and vegetables was found to be associated with lower food security (P < 0·01), poorer child diet quality (P < 0·01) and reduced availability of a variety of fruits (P < 0·01), vegetables (P < 0·05) and whole grains in the home (P < 0·01). Moreover, residing in a food desert was found to be associated with a higher child BMI percentile if the child's household was food insecure (P < 0·05). No differences in associations were found for immigrant/refugee groups. CONCLUSIONS: Poor NFE were associated with worse weight-related outcomes for children; the association with weight was more pronounced among children with HFI. Interventions aiming to improve child weight-related outcomes should consider both NFE and HFI.

Maternal employment and child weight-related health.

Several studies have documented a link between maternal employment and childhood obesity, but the mechanisms are not clear. This study investigated the association of maternal employment with children's weight status and detailed weight-related behaviors using data from Phase I of Family Matters, a cross-sectional, observational study of 150 children aged 5-8 from six racial/ethnic groups (White, Black, Latinx, Native American, Hmong, and Somali) and their families from the Minneapolis/St. Paul, MN metropolitan area recruited in 2015-2016. Weight status (objectively measured), child dietary intake (three 24-h dietary recalls), physical activity (eight days of hip-mounted accelerometer data on children), and sleep (eight daily parent reports on children's sleep hours) were examined across four categories of maternal employment status: stay-at-home caregivers, working part-time, working full-time, and unemployed/unable to work. This study found that children's weight status and physical activity levels were similar across all categories of maternal employment. However, there were significant differences in aspects of children's diets by maternal employment status and, compared to children with stay-at-home mothers, children's sleep was significantly lower if their mother worked full-time. These findings highlight that dietary and sleep interventions tailored to the mother's employment status may be fruitful.

Exploring associations between social determinants of health and mental health outcomes in families from socioeconomically and racially and ethnically diverse households.

This cross-sectional study investigated the associations between Social Determinants of Health (SDOH) and mental health outcomes of parents and children (n = 1307) from the Latinx, Native American, Somali/Ethiopian, White, Hmong, and African American communities. Logistic regression models were used to estimate the adjusted associations between five parent and child mental health measures and 25 measures of SDOH. False discovery rate q-values were computed to account for multiple comparisons. Families of color reported 5.3-7.8 SDOH barriers while White families reported 1.7 SDOH barriers on average. Adjusted analyses indicated that low family functioning and high perceived discrimination were associated with low resiliency among parents and increased behavioral difficulties among children. Other SDOH that were adversely associated with parent or child mental health included lack of social support, recent stressful life events, and adverse childhood experiences among parents. SDOH in the social and community context were most likely to be associated with mental health problems. Community-engaged evidence-based interventions are needed to improve population mental health.

Supplemental Nutrition Assistance Program Participation is Associated with Lower Health Care Spending among Working Age Adults without Dependents.

Prior evidence suggests an association among food insecurity, poor health, and increased health care spending. In this study, we are using a natural experiment to confirm if longer participation in the Supplemental Nutrition Assistance Program (SNAP) is associated with reduced Medicaid spending among a highly impoverished group of adults. In 2013, the mandatory work requirements associated with SNAP benefits were lifted for able-bodied adults without dependents (ABAWDs). Using 2013 to 2015 Medicaid and SNAP data of 24,181 Minnesotans aged 18-49, we examined if changes in SNAP enrollment duration affect health care expenditures. In fully adjusted within-participant regression models, for each additional month of SNAP, average annual health care spending was $98.8 lower (95% CI: -131.7, -66.0; p<.001) per person. Our data suggests that allowing ABAWDs to receive SNAP even in months they are not working may be critical to their health as well as cost-effective.

Participant characteristics and dietary correlates of SNAP and other assistance programs among families with children from racially and ethnically diverse households.

The objective of this study was to describe food purchasing behaviors and the home food environment across families simultaneously receiving SNAP (Supplemental Nutrition Assistance Program) and other cash and food assistance benefits, and assess how child dietary intake varied across three distinct categories of assistance (i.e., SNAP and other assistance programs, assistance programs other than SNAP, and not enrolled in any assistance program). This cross-sectional study was conducted with parents of children aged 5-9 years (N = 1033) from low-income and racially and ethnically diverse households, living in Minneapolis and Saint Paul, Minnesota, metropolitan areas. In an online survey, parents reported enrollment in seven assistance programs (SNAP, WIC [Special Supplemental Nutrition Program for Women, Infants and Children Program], free or reduced-cost school breakfast, free or reduced-cost school lunch, SSI [Supplemental Security Income Program], MFIP [Minnesota Family Investment Program], daycare assistance), food purchasing behaviors, the home food environment, and child dietary and fast-food intake. Descriptive statistics were computed to describe food purchasing behaviors and the home food environment. Multivariable linear regressions were used to evaluate the association between assistance categories and child dietary intake factors. Models were adjusted for child age, parent and child sex, race and ethnicity, household income, primary caregiver's educational attainment, employment status, and place of birth. Relative to families participating in assistance programs other than SNAP and not enrolled in any assistance program, families participating in SNAP and other assistance programs had less reliable modes of transportation to go food shopping (use 'my own car or vehicle' 57% vs. 90% and 83%, respectively), shopped less frequently during the month ('1 big trip a month and small trips in between' 35% vs. 19% and 24%, respectively], had a somewhat higher presence of energy-dense (e.g., 'French fries' 60% vs. 35% and 25%, respectively) and high-sodium food items in the home (e.g., 'canned pasta' meals 48% vs. 35% and 20%, respectively), and some aspects of children's dietary intake that were not congruent with current dietary recommendations (e.g., consumption of 'fried vegetables' 3.9 times/week [95% CI 3.4, 4.4] vs. 2.9 [2.3, 3.5] and 2.8 [2.1, 3.6], respectively). Findings could inform targeted strategies to maximize the impact of simultaneous programs' benefits on improving child dietary intake and reaching eligible households not enrolled in assistance programs.

How time in the US and race/ethnicity shape food parenting practices and child diet quality.

Childhood obesity prevalence is high among children from immigrant/refugee households who live in high-income countries. Poor child dietary intake is a critical risk factor for elevated obesity prevalence and food parenting practices have been found to be associated with child dietary intake and eating behaviors. The main aim of this study was to examine the associations between migrants'/refugees' food parenting practices, the length of residence time in the US, race/ethnicity, and child diet quality. The current study included 577 families from three racial/ethnic groups that include mostly foreign-born parents (Latino, Hmong, and Somali/Ethiopian), and a comparison group of 239 non-Hispanic White families. Results showed that for Latino and Hmong parents, some food parenting practices varied by how long they had lived in the US. For example, more recently moved parents engaged in more non-directive (e.g., avoid buying sweets) practices compared with US-born parents. In contrast, Somali/Ethiopian parents engaged in different food parenting practices than White parents, regardless of time in the US. Results also showed that diet quality among Hmong children was lower if their parents were US-born compared to foreign-born. Future researchers may want to consider studying why some food parenting practices change when parents move to the US and explore whether there is a combination of food parenting practices that are most useful in promoting a healthful child's diet and weight among immigrant and refugee families.

Factors associated with accurate reporting of public and private health insurance type.

OBJECTIVE: To examine factors associated with accurate reporting of private and public health insurance coverage. DATA SOURCES: Minnesota health plan enrollment records provided the sample for the Comparing Health Insurance Measurement Error (CHIME) study, a survey conducted in 2015 that randomly assigned enrollees to treatments that included health insurance questions from the American Community Survey (ACS) or the redesigned Current Population Survey Annual Social and Economic Supplement (CPS). STUDY DESIGN: Reverse record check study that compared CHIME study survey responses to enrollment records of coverage type (direct purchase on and off the Marketplace, Medicaid, or MinnesotaCare), service use, subsidy receipt, and duration of coverage from a major insurer. DATA COLLECTION METHODS: Using matched enrollment and CHIME survey data and logistic regression, we examined correlates of accurate insurance type reporting, including characteristics of the insurance coverage, the covered individual, respondent, and family. PRINCIPAL FINDINGS: Reporting accuracy across treatment and coverage type is high (77%-84%). As with past research, accurate reporting of public insurance is higher for people with characteristics consistent with eligibility for public insurance for both survey treatments. For the ACS treatment, reports of direct purchase insurance are more accurate for enrollees who receive a premium subsidy. CONCLUSIONS: Given the complexity of health insurance measurement and frequently changing policy environment, differences in reporting accuracy across treatments or coverage types are not surprising. Several results have important implications for data editing and modeling routines. First, adding premium and subsidy questions in federal surveys should prove useful given the finding that subsidy receipt is associated with reporting accuracy. Second, across both survey treatments, people whose opportunity structures (race, ethnicity, and income) match public program eligibility are accurate reporters of this coverage. This evidence supports using these commonly collected demographic variables in simulation, imputation, and editing routines.

Kitchen Adequacy and Child Diet Quality in a Racially/Ethnically Diverse Sample.

This study examined kitchen adequacy in a racially/ethnically diverse low-income sample and associations with child diet quality. Families with children age five to seven years old (n = 150) from non-Hispanic white, non-Hispanic Black, Hispanic, Native American, Hmong, and Somali families were recruited through primary care clinics. More than 85% of families had 15 of the 20 kitchen items queried, indicating that the sample had adequate kitchen facilities. Only one item (a kitchen table) was associated with higher overall diet quality of children. In contrast, children living in households with can openers and measuring spoons consumed more sodium and added sugars, respectively.

Ecological Momentary Assessment of Weight-Related Behaviors in the Home Environment of Children From Low-Income and Racially and Ethnically Diverse Households: Development and Usability Study.

BACKGROUND: Ecological momentary assessment (EMA) is an innovative tool for capturing in-the-moment health behaviors as people go about their daily lives. EMA is an ideal tool to measure weight-related behaviors, such as parental 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: To answer the call for reporting study designs using EMA, this paper describes in detail the EMA design of the Family Matters study and how it was adapted over time to improve functionality and meet the needs of a racially, ethnically, and socioeconomically diverse sample. METHODS: Family Matters is an incremental, 2-phased, mixed methods study, conducted with a racially and ethnically diverse, immigrant and refugee sample from largely low-income households, designed to examine risk and protective factors for child weight and weight-related behaviors 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 1 of the study completed 8 days of EMA on their smartphones, which included signal-contingent surveys (eg, asking about the parent's stress at the time of the survey), event-contingent surveys (eg, descriptions of the meal the child ate), and end-of-day surveys (eg, overall assessment of the child's day). RESULTS: A detailed description of EMA strategies, protocols, and methods used in phase 1 of the Family Matters study is provided. Compliance with EMA surveys and participants' time spent completing EMA surveys are presented and stratified by race and ethnicity. In addition, lessons learned while conducting phase 1 EMA are shared to document how EMA methods were improved and expanded upon for phase 2 of the Family Matters study. CONCLUSIONS: The results from this study provided an important next step in identifying best practices for EMA use in assessing weight-related behaviors in the home environment.

Examining the Relationship Between Parental Stress and Girls' and Boys' Physical Activity Among Racially/Ethnically Diverse and Immigrant/Refugee Populations.

Given the high prevalence of overweight/obesity and the low prevalence of engaging in physical activity in children, it is important to identify barriers that impede child physical activity. One potential barrier is parental stress. The current study examined the association between parental stress levels and girls' and boys' moderate to vigorous physical activity. Children aged 5-7 years and their families (n = 150) from 6 racial/ethnic groups (n = 25 each Black, Hispanic, Hmong, Native American, Somali, and White families) were recruited for the Family Matters mixed-methods study in 2015 through primary care clinics in Minneapolis and St Paul, MN. Two in-home visits were carried out with families 10 days apart for data collection, with an 8-day observational period in between when children wore accelerometers. Higher parental stress levels were associated with fewer minutes of moderate to vigorous physical activity in girls (P < .05) compared with boys. On average, girls with a parent reporting a stress rating of 10 engaged in 24 minutes less of physical activity per day than girls with a parent with a stress rating of 1. The results suggest that parental stress may reduce girls' engagement in physical activity. The implications of these results include targeting parental stress and coping skills in future physical activity interventions. In addition, when addressing child physical activity in health care visits with parents and daughters, providers may want to focus their anticipatory guidance on parental stress and coping skills in addition to providing resources to help parents manage stress.

The effect of a fresh produce incentive paired with cooking and nutrition education on healthy eating in low-income households: a pilot study.

OBJECTIVE: This study pilot-tested combining financial incentives to purchase fruits and vegetables with nutrition education focused on cooking to increase the consumption of fruits and vegetables and improve attitudes around healthy eating on a budget among low-income adults. The goal of the pilot study was to examine implementation feasibility and fidelity, acceptability of the intervention components by participants and effectiveness. DESIGN: The study design was a pre-post individual-level comparison without a control group. The pilot intervention included two components, a scan card providing free produce up to a weekly maximum dollar amount for use over a 2-month period, and two sessions of tailored nutrition and cooking education. Outcomes included self-reported attitudes about healthy eating and daily fruit and vegetable consumption from one 24-h dietary recall collected before and after the intervention. SETTING: Greater Minneapolis/St. Paul area in Minnesota. PARTICIPANTS: Adults (n 120) were recruited from five community food pantries. RESULTS: Findings indicated that the financial incentive component of the intervention was highly feasible and acceptable to participants, but attendance at the nutrition education sessions was moderate. Participants had a statistically significant increase in the consumption of fruit, from an average of 1·00 cup/d to 1·78 cups/d (P < 0·001), but no significant change in vegetable consumption or attitudes with respect to their ability to put together a healthy meal. CONCLUSIONS: While combining financial incentives with nutrition education appears to be acceptable to low-income adult participants, barriers to attend nutrition education sessions need to be addressed in future research.

Family meal characteristics in racially/ethnically diverse and immigrant/refugee households by household food security status: A mixed methods study.

While there is some research examining frequency of family meals by food insecurity (FI) status, there is little research examining other family meal characteristics (e.g., type of food served at meal, emotional atmosphere) or parent feeding practices by FI status. If food and money is scarce, it may be that the broader family meal environment looks different in families with continuous access to food (food secure, FS) compared to families with FI. Using ecological momentary assessment (EMA) and qualitative data, this study explores meal characteristics and parent feeding practices at nearly 4000 family meals in a low-income, racially/ethnically diverse and immigrant/refugee sample. For 8 days, participants (i.e., parents of 5-7-year-old children) completed a survey every time they shared a meal with their child. Additionally, parents completed a qualitative interview regarding family meals. There were many meal characteristics statistically correlated with a family being FI, including: who prepared the meal and how the meal was prepared, the makeup of people at the meal, the meal location and meal atmosphere, and the food served at the meal. Qualitative data illuminated many of these findings from EMA meal surveys. Quantitatively, families with FI and FS reported similar parent feeding practices during family meals. Qualitatively, families with FI and FS reported differences in (1) parent feeding practices; (2) food served at family meals; (3) challenges to having family meals; and 4) adults' role in the family meal. This study provides suggestions for interventionists working with families, including helping families identify time management strategies, including fruits and vegetables into family meals on a budget, reducing screen time at family meals while improving the meal's emotional atmosphere, and developing positive parent feeding practice strategies.

Concordance of children's intake of selected food groups as reported by parents via 24-h dietary recall and ecological momentary assessment.

OBJECTIVE: To understand how dietary intake data collected via a brief ecological momentary assessment (EMA) measure compares to that of data collected via interviewer-administered 24-h dietary recalls, and explore differences in level of concordance between these two assessment types by individual- and meal-level characteristics. DESIGN: Parents completed three 24-h dietary recalls and 8 d of brief EMA surveys on behalf of their child; in total, there were 185 d where dietary intake data from both EMA and 24-h recall were available. The EMA measure asked parents to indicate whether (yes/no) their child had consumed any of the nine total food items (e.g. fruit, vegetable, etc.) at eating occasions where both the child and parent were present. SETTING: Twenty-four-hour dietary recalls were completed in person in the study participant's home; participants completed EMA surveys using a study provided in iPad or their personal cell phone. PARTICIPANTS: A diverse, population-based sample of parent-child dyads (n 150). RESULTS: Among meals reported in both the EMA and dietary recalls, concordance of reporting of specific types of food ranged from moderate agreement for meat (kappa = 0·55); fair agreement for sweets (kappa = 0·38), beans/nuts (kappa = 0·37), dairy (kappa = 0·31), fruit (kappa = 0·31) and vegetables (kappa = 0·27); and little to no agreement for refined grains, whole grains and sweetened beverages (73 % overall agreement; kappa = 0·14). Concordance of reporting was highest for breakfast and snacks, as compared with other eating occasions. Higher concordance was observed between the two measures if the meal occurred at home. CONCLUSIONS: Data suggest that among meals reported in both the EMA and dietary recalls, concordance in reporting was reasonably good for some types of food but only fair or poor for others.
