RESUMO

BACKGROUND: Studies have demonstrated relations between food insecurity, the lack of access to enough nutritious food, and greater risk of diet-sensitive chronic diseases. However, most prior evidence relies on cross-sectional studies and self-reported disease. OBJECTIVES: The objective was to assess the longitudinal relation between risk of food insecurity in young adulthood and changes in diet-sensitive cardiometabolic health outcomes across 10 y among non-Hispanic white, non-Hispanic black, American Indian or Alaska Native, and Hispanic adults. METHODS: Data from the fourth and fifth waves (n = 3992) of the National Longitudinal Study of Adolescent to Adult Health were used. Measures included risk of food insecurity, body weight, diabetes, and sociodemographic characteristics. Body weight and diabetes were assessed with direct measures. Mixed-effects models assessed the association of risk of food insecurity with BMI, obesity, and diabetes while accounting for sociodemographic characteristics and the complex survey design. RESULTS: Risk of food insecurity was associated with increases in BMI as well as incidence of obesity and diabetes from young to middle adulthood in unadjusted and adjusted models (all P < 0.01). In models stratified by race and ethnicity, the relations of risk of food insecurity with body weight outcomes and diabetes varied. CONCLUSIONS: Risk of food insecurity in young adulthood was related to BMI and obesity during young and middle adulthood but not in changes over time. Risk of food insecurity in young adulthood related to an increased incidence of diabetes in middle adulthood. However, the relations among specific racial and ethnic groups were unclear. Estimates of the relation between food insecurity and cardiometabolic health outcomes within racial and ethnic groups experiencing the highest prevalence of these conditions should be refined.

RESUMO

BACKGROUND: Environmental distractions have been shown to affect eating patterns. OBJECTIVE: The purpose of this study was to determine the effects of a cognitive distraction on amount, preference, and memory of food consumed and perceptions of fullness, hunger, and enjoyment of food in a healthy young-adult population. METHODS: A randomized controlled crossover study of 119 healthy adults (20.2 ± 1.4 y; 57% women; 48% white) assigned participants to begin under either the distracted (DIS, n = 55) or control (CON, n = 64) conditions. DIS participants consumed a meal of quiche while completing a Rapid Visual Information Processing (RVIP) for 15 min. CON participants ate without any task assignment. After a 30-min rest period, participants were offered a snack and given 5 min to eat ad libitum. Participants completed a survey assessing fullness, hunger, and enjoyment of the meal using 100 mm visual analogue scales. One week later, participants completed the opposite condition. Data were analyzed using ANOVA. RESULTS: Those in DIS consumed 13 g less of the meal (P < 0.001), even when comparing by initial condition (P < 0.001) and adjusting for sex (P < 0.001). A carryover effect of initial condition was found (P < 0.001), such that participants first assigned to DIS condition consumed less (95.2 ± 61.7 g) when distracted compared to all other condition combinations (127-133 g). Those in DIS had decreased accuracy for both memory of quiche received (absolute difference, 1.1 ± 1.6 compared with 0.7 ± 1.2 for CON, P < 0.001) and memory of quiche consumed (0.8 ± 1.1 for DIS compared with 0.7 ± 1.2 for CON, P = 0.007). CONCLUSIONS: When distracted, healthy young adults consumed significantly less food and their memory of the meal was dampened. These findings underscore the potential importance of cognitive distraction in affecting food intake. This trial was registered at clinicaltrials.gov as NCT04078607.

RESUMO

BACKGROUND: Food insecurity (FI) - the lack of sufficient access to food to maintain a healthy lifestyle - among college (i.e. post-secondary or higher education institution) students has become a prominent issue in the U.S. However, it is not clear if high rates of FI among students are due to the modern experience in higher education institutions or due to underlying issues in common surveying methods. To understand if there were underlying content validity issues, the present study had two primary research questions: 1) How do students interpret the U.S. Department of Agriculture (USDA) Food Security Survey Module (FSSM) questionnaire items, and 2) How do responses of students experiencing FI compare with the theorized experiences and coping responses? METHODS: Thirty-three undergraduate students, aged 18- to 24-years old and fluent in English were recruited from a single 4-year university. During a 60-min session, participants completed the 10-item Adult FSSM and then were cognitively interviewed about their responses using the think-aloud method. Interview transcripts were analysed by two researchers using a collaborative process and basic interpretative approach. RESULTS: Students were on average 19.5 years old (± 1.2 years), the majority were in their freshman or sophomore (i.e., first or second) year, and 67% (n = 22) experienced FI. Results indicated that students' interpretations of key terms - such as "money for more," "balanced meals," and "real hunger" - diverge from expectations. Furthermore, students categorized as food insecure reported experiences and responses to FI that varied from theoretical dimensions of the process. CONCLUSIONS: Though limited by sample size and representativeness, the present results indicate that the content validity of the FSSM may be compromised in this population and the managed process of FI may present differently among college students. Further psychometric research on modifications to the FSSM or with new FI assessment tools should be conducted with college students.

RESUMO

U.S. consumers, namely young adults, are one of the largest sources of preventable food waste. However, the antecedents of wasted food among young adults in the U.S. are unknown. This study aimed to explore the perceptions, beliefs and behaviors related to wasted food among 18- to 24-year-old adults. Fifty-eight individuals (63.8% female) with an average age of 20.2 y (±1.6) who lived in a residence where they had control over some food purchases (excluding co-op or other communal housing, and living with parents) participated in 75-min focus groups during spring of 2016. Thirty participants lived in residence halls at a university and the remaining 28 lived in off-campus dwellings. Focus group transcriptions were analyzed for themes by two investigators using a constant-comparative approach. Inductive thematic analyses provided insights that were broadly categorized into: 1) awareness and knowledge of wasted food, 2) factors that influence food waste behaviors, and 3) suggested interventions to reduce wasted food. Results provide evidence of heterogeneity in perceptions, beliefs, and behaviors related to wasted food based on dwelling type. Insights from the current study may be used to inform observational or intervention work focused on reducing wasted food by young adults.

RESUMO

OBJECTIVE: To examine risk factors for gestational diabetes mellitus (GDM) and factors associated with breastfeeding patterns among women with GDM from different racial/ethnic groups. METHODS: We used data from Phase 8 (2016-2018) of the Pregnancy Risk Assessment Monitoring System. We used logistic regression to estimate factors associated with GDM and with breastfeeding initiation, and conducted survival analysis using Kaplan-Meier curves, and Cox proportional hazards regression to analyze early cessation of breastfeeding. RESULTS: Among American Indian and Alaska Native (AI/AN) women, higher education reduced odds (aOR = 0.33; 95% CI: 0.19-0.59) and being married increased odds (aOR = 1.35; 95% CI: 1.02-1.79) of GDM. AI/AN women who received WIC benefits had lower odds of initiating breastfeeding (aOR = 0.70; 95% CI: 0.51-0.95). While there was no association between GDM and initiation of breastfeeding, only a third of AI/AN women with GDM were still breastfeeding by 36 weeks postpartum, compared to more than half of non-Hispanic White and Hispanic women. CONCLUSIONS FOR PRACTICE: Efforts to reduce GDM among those most at risk are needed, especially among racial and ethnic minorities. Increasing support for women with GDM to continue to breastfeed may improve maternal and child health outcomes and reduce health disparities, particularly among AI/AN women.

RESUMO

OBJECTIVES: Our aim was to assess the cross-sectional associations between food insecurity and cardiometabolic health indicators in American Indian young adults compared with non-Hispanic white, black, Asian or Pacific Islander and Hispanic young adults. DESIGN: Data from the fourth wave of the National Longitudinal Study of Adolescent to Adult Health (Add Health) were used. Variables included a self-assessed measure of risk of food insecurity, indicators of cardiometabolic health (body mass index, haemoglobin A1c, blood pressure) and sociodemographic characteristics. Multivariable regression models were used to assess the association of risk of food insecurity with cardiometabolic health, while controlling for sociodemographic variables. All analyses were weighted and accounted for the complex survey design. PARTICIPANTS: The analytical sample of n=12 799 included mostly non-Hispanic white respondents (n=7900), followed by n=2666 black, n=442 American Indian, n=848 Asian or Pacific Islander and n=943 Hispanic. RESULTS: Risk of food insecurity was more common among respondents who were female, Black, American Indian, had lower educational attainment, and were classified as having obesity or diabetes. In unadjusted models, risk of food insecurity was significantly associated with greater odds of obesity (OR=1.39; 95% CI 1.20 to 1.60) and diabetes (OR=1.61; 95% CI 1.23 to 2.11). After adjusting for sociodemographic factors (age, sex, education, income, household size, tobacco smoking, alcohol intake and race/ethnicity), only the association between risk of food insecurity and obesity remained (OR=1.19; 95% CI 1.03 to 1.38). Relationships among risk of food insecurity, sociodemographic characteristics and diabetes varied across models stratified by race and ethnicity. CONCLUSIONS: Results suggest that elevated risk of food insecurity is present in young American Indian adults, but its relationship with cardiometabolic health is unclear. Future work should capitalise on longitudinal data and the US Department of Agriculture's Food Security Survey Modules.

RESUMO

Objective: To increase vegetable and fruit intake, reduce body mass index (BMI), and improve parental blood pressure among American Indian families. Design: Randomized, wait-list controlled trial testing a multi-level (environmental, community, family, and individual) multi-component intervention with data collection at baseline and 6 months post-intervention. Setting: Tribally owned and operated Early Childhood Education (ECE) programs in the Osage Nation in Oklahoma. Participants: American Indian families (at least one adult and one child in a ECE program). A sample size of 168 per group will provide power to detect differences in fruit and vegetable intake. Intervention: The 6-month intervention consisted of a (1) ECE-based nutrition and gardening curriculum; (2) nutrition education and food sovereignty curriculum for adults; and (3) ECE program menu modifications. Main Outcome Measures: The primary outcome is increase in fruit and vegetable intake, assessed with a 24-h recall for adults and plate weight assessments for children. Secondary outcomes included objective measures of BMI among adults and children and blood pressure among adults.

RESUMO

Food insecurity, defined as insufficient access to nutritious foods, is a social determinant of health that may underpin health disparities in the US. American Indian and Alaska Native (AI/AN) individuals experience many health inequities that may be related to food insecurity, but no systematic analyses of the existing evidence have been published. Thus, the objective of this scoping review was to assess the literature on food insecurity among AI/AN individuals and communities, with a focus on the prevalence of food insecurity and its relations to sociodemographic, nutrition, and health characteristics. Systematic search and data extraction processes were used. Searches were conducted on PubMed as well as peer-reviewed journal and government websites. Of 3174 identified references, 34 publications describing 30 studies with predominantly AI/AN sample populations were included in the final narrative synthesis. Twenty-two studies (73%) were cross-sectional and the remaining 8 (27%) described interventions. The weighted average prevalence of food insecurity across the studies was 45.7%, although estimates varied from 16% to 80%. Most studies used some version of the USDA Food Security Survey Modules, although evidence supporting its validity in AI/AN respondents is limited. Based on the review, recommendations for future research were derived, which include fundamental validity testing, better representation of AI/AN individuals in federal or local food security reports, and consideration of cultural contexts when selecting methodological approaches. Advances in AI/AN food insecurity research could yield tangible benefits to ongoing initiatives aimed at increasing access to traditional foods, improving food environments on reservations and homelands, and supporting food sovereignty.

RESUMO

OBJECTIVE: To assess changes in food pantries' consumer nutrition environment (CNE) after the provision of technical assistance. DESIGN: Pre-post study with 2 phases. SETTING: Staff completed observational assessments using the Nutrition Environment Food Pantry Assessment Tool (NEFPAT) at food pantries in an initial pilot phase. Then, staff conducted NEFPAT observations at pantries in Illinois statewide. PARTICIPANTS: In the pilot phase, 6 staff assessed 28 pantries. In the statewide phase, 35 staff assessed 119 pantries. INTERVENTION: After completing an initial NEFPAT at each pantry, technical assistance was provided by staff to support changes in the pantries' CNE before another NEFPAT observation was completed. MAIN OUTCOME MEASURE: Changes in the CNE, as assessed with the NEFPAT, when comparing preassessment and postassessment. ANALYSIS: Score differences were evaluated with paired t tests. RESULTS: In the pilot phase, among 23 pantries with preassessment and postassessment data, 2 objectives on the NEFPAT observation increased significantly. In the statewide phase, among 66 pantries with preassessment and postassessment data, most NEFPAT objectives and the overall NEFPAT score (22.12 ± 8.16 vs 28.20 ± 7.14, P < 0.001) significantly increased. CONCLUSIONS AND IMPLICATIONS: Technical assistance provided by Supplemental Nutrition Assistance Program Education implementing staff were related to improvements in the CNE of food pantries in Illinois. Future work should evaluate the association of these CNE changes with changes in behavior among pantry patrons.

RESUMO

Evidence suggests that perceived stress and psychological resilience are related to the presence and severity of cardiometabolic disease. Despite increased stress and cardiometabolic disease burden among American Indian and Alaska Native (AI/AN) people, the relationships between these factors are not well established in these populations. The objective of this study was to evaluate the relationships of stress with five cardiometabolic health indicators and to assess whether psychological resilience mediates these relationships in AI/AN adults. Four hundred and ninety-six AI/AN attendees were surveyed at three powwows. The questionnaire included sociodemographic items, questions on self-reported obesity, prediabetes, diabetes, high blood pressure, and high cholesterol, the Perceived Stress Scale, and the Brief Resilience Scale. Multivariable logistic regression models were used to measure associations of health indicators with Perceived Stress Scale and Brief Resilience Scale scores while controlling for sociodemographic characteristics. Among respondents, obesity was the most common cardiometabolic health indicator reported (48%), followed by high blood pressure, prediabetes, diabetes, and high cholesterol. Mean Perceived Stress Scale and Brief Resilience Scale scores were 16.1 (6.4 SD) and 3.5 (0.7 SD), respectively. Higher Perceived Stress Scale scores were associated with greater odds of self-reported prediabetes and diabetes. Brief Resilience Scale scores did not serve as a mediator. These results suggest that perceived stress is associated with some self-reported indicators of cardiometabolic health among AI/AN adults, but findings are limited by the convenience sample, reliance on self-report, and cross-sectional design. Future work should capitalize on nationally representative data, longitudinal designs, and objective measures of cardiometabolic health.

RESUMO

Objectives: Literature suggests that college (ie, post-secondary) students experience food insecurity (FI) at alarming rates. However, the commonly used FI questionnaires have undergone limited evaluations for accuracy in this sub-population. The objective of this exploratory study was to evaluate if FI estimates among college students differ by survey distribution modality. Methods: A test-retest study was conducted from October to December 2017. A random sample of undergraduate students (N = 343) participated in an online survey. After completing the survey, a random sample of these students (N = 66; 29%) completed the same items in paper-and-pencil format. Responses were compared with percent agreement and kappa (κ) coefficients. Results: Students were less likely to affirm each item on paper-and-pencil questionnaires. Percent agreement ranged from 71.2% to 96.9% across items, and κ coefficients ranged from poor to fair. FI prevalence differed by 15% between online and paper-and-pencil assessments (40.9% and 25.8%, respectively). Percent agreement for FI categorization was 75.8% and κ=0.47. Conclusions: Differing survey modalities resulted in varying FI classifications in a sample of under-graduate students. Though limited by size and representativeness, this supports the need for further testing of FI surveys, as accurate FI estimates are essential to serving college students.

RESUMO

Reports of college students experiencing food insecurity (FI), defined as inadequate access, availability, adequacy, and stability of food, have sparked national calls for alleviation and prevention policies. However, there are a wide variety of FI rates reported across studies and even among recent literature reviews. The current scoping review aimed to develop a weighted estimated prevalence of FI among US students using a comprehensive search approach. In addition, study characteristics that may be related to the high variability in reported FI prevalence were explored. To address these aims, the peer-reviewed and gray literature on US college student FI was systematically searched to identify 12,044 nonduplicated records. A total of 51 study samples, across 62 records, met inclusion criteria and were included in the current review. The quality of the included studies was moderate, with an average rate of 6.4 on a scale of 0-10. Convenience (45%) and census (30%) sampling approaches were common; only 4 study samples were based on representative sampling strategies. FI estimates ranged from 10% to 75%. It was common for very low security to be as prevalent as, or more prevalent than, low food security. The surveying protocols used in the studies were related to the FI estimates. The USDA Short Form Food Security Survey Module (FSSM; 50%) and the USDA Adult FSSM (40%) prevalence estimates were larger than for the full USDA Household FSSM (13%). When these surveys referenced a 12-mo period, FI estimates were 31%. This was a lower FI estimate than surveys using reference periods of 9 mo or shorter (47%). The results indicate that FI is a pressing issue among college students, but the variation in prevalence produced by differing surveys suggests that students may be misclassified with current surveying methods. Psychometric testing of these surveys when used with college students is warranted.

RESUMO

A growing body of literature suggests that post-secondary students experience food insecurity (FI) at greater rates than the general population. However, these rates vary dramatically across institutions and studies. FI assessment methods commonly used in studies with college students have not been scrutinized for psychometric properties, and varying protocols may influence resulting FI prevalence estimates. The objective of this study was to assess the performance of standard food security assessment protocols and to evaluate their agreement as well as the relative accuracy of these protocols in identifying student FI. A randomized sample of 4,000 undergraduate students were invited to participate in an online survey (Qualtrics, LLC, Provo, Utah, USA) that evaluated sociodemographic characteristics and FI with the 2-item food sufficiency screener and the 10-item USDA Adult Food Security Survey Module (FSSM; containing the abbreviated 6-item module). Four hundred sixty-two eligible responses were included in the final sample. The psychometric analysis revealed inconsistencies in college student response patterns on the FSSM when compared to national evaluations. Agreement between FI protocols was generally high (>90%) but was lessened when compared with a protocol that incorporated the 2-item screener. The 10-item FSSM with the 2-item screener had the best model fit (McFadden's R2 = 0.15 and Bayesian Information Criterion = -2049.72) and emerged as the tool providing the greatest relative accuracy for identifying students with FI. Though the 10-item FSSM and 2-item screener yields the most accuracy in this sample, it is unknown why students respond to FSSM items differently than the general population. Further qualitative and quantitative evaluations are needed to determine which assessment protocol is the most valid and reliable for use in accurately identifying FI in post-secondary students across the U.S.

RESUMO

OBJECTIVE: To identify participant characteristics and study methodology that influenced the completion of a 15-month community-based longitudinal study evaluating the impact of the Supplemental Nutrition Assistance Program Education and Expanded Food and Nutrition Education Program. DESIGN: Observational longitudinal 15-month study across 12 data collection timepoints. Sociodemographic characteristics were collected with a paper-based survey at baseline. SETTING: Five counties across central and southern Illinois. PARTICIPANTS: Women, aged 18 to 65 years (n = 297), recruited at sites likely to serve families eligible for the Supplemental Nutrition Assistance Program Education and Expanded Food and Nutrition Education Program (housing departments, child care centers, etc). MAIN OUTCOME MEASURES: Predictors of participant attrition during the study duration. ANALYSIS: Cox proportional hazard models. RESULTS: Ninety-seven participants were retained across the full study. In unadjusted models, greater income and education levels were significantly related to lower attrition; however, this relationship did not persist in a multivariate model. When adjusted for other characteristics, larger household size was the only measured variable significantly related to greater odds of attrition (odds ratio = 1.09; 95% confidence interval = 1.02, 1.17). CONCLUSIONS AND IMPLICATIONS: Several characteristics predicting attrition in other settings were not significant in this study. Future attrition analyses that evaluate social support, transportation capacity, and type of phone in longitudinal nutrition education studies are warranted.

RESUMO

Objective: In this study, we evaluated the afterschool PAWS (Peer-education About Weight Steadiness) Club program delivered by peer or adult educators to improve food choices, physical activity, and psychosocial variables related to healthy eating. Methods: We had 109 adolescents (53 in adult-led group; 56 in peer-led group) participate in a cluster randomized controlled intervention. The 12-session curriculum framed within Social Cognitive Theory (SCT) and Stages of Change addressed mediators of behavior change related to cooking skills, food intake, and physical activity. Anthropometric, dietary intake, physical activity, and SCT mediators were assessed at baseline, post-intervention, and 6-months post-intervention. Results: Adolescents in the peer-led group significantly improved whole grain intake at post-intervention (p = .017) and 6-months post-intervention (p = .014). Both peer-led and adult-led groups had significant reductions in caloric intake at 6-months post-intervention (p = .047). Only the adult-led group improved self-efficacy (SE) and social/family support (SS) for healthy eating at post-intervention [p = .019 (SE); p = .048 (SS)] and 6-months post-intervention [p = .036 (SE); p = .022 (SS)]. Conclusions: The PAWS Club program promoted lower caloric intake by adolescents. Peer educators were effective at increasing whole grains in adolescents, and adult educators contributed to positive changes in SE and SS related to healthy eating.

RESUMO

Objectives: We investigated whether the Short Grit Scale (Grit-S) predicted odds of food insecurity (FI) among adults and their children. Methods: A cross-sectional panel of parent-child dyads completed an online questionnaire. Eligible dyads included parents with household income below the 2015 median ($52,250 USD/year) and their self-selected household child between the ages of 13 to 17 years. An online questionnaire assessed: (1) FI using the 18-item Household Food Security Survey Module and the Food Security Survey Module for Youth; (2) perseverance and determination using the validated 8-item Grit-S; and (3) sociodemographic FI predictors. Logit regression models estimated the relationship between odds of FI and predictors among parents and children, separately. Results: Among 252 parents, 61.1% reported household FI. Parents' Grit-S score (N = 179) was associated with a significantly lower odds of household FI (OR= 0.4; 95%CI= 0.2, 0.8; p < .01) while adjusting for established predictors. Mean (±SD) Grit-S was 3.1 (±0.7). Children's Grit-S score (N = 178) was associated with a significantly lower odds of child FI (OR= 0.6; 95%CI= 0.4, 0.9; p < .05) while adjusting for established predictors. Conclusions: Perseverance and determination, also known as "grit," may be one further explanation for why some poor households are food secure.

RESUMO

OBJECTIVE: To develop and evaluate a nutrition environment assessment tool to assess the consumer nutrition environment and use of recommended practices in food pantries. METHODS: The Nutrition Environment Food Pantry Assessment Tool (NEFPAT) was developed based on a literature review and guidance from professionals working with food pantries. The tool was pilot-tested at 9 food pantries, an expert panel assessed content validity, and interrater reliability was evaluated by pairs in 3 pantries. After revisions, the NEFPAT was used in 27 pantries. RESULTS: Pilot tests indicated positive appraisal for the NEFPAT and recommendations were addressed. The NEFPAT's 6 objectives and the overall tool were rated as content valid by experts, with an average section rating of 3.85 ± 0.10. Intraclass correlation coefficients for interrater reliability were >0.90. CONCLUSIONS AND IMPLICATIONS: The NEFPAT is content valid with high interrater reliability. It provides baseline data that could be valuable for interventions within the nutrition environment of food pantries.

RESUMO

OBJECTIVES: We evaluated the feasibility of a menu-planning workshop led by adults or by adolescents (ie, peers), delivered to parents and their adolescent children. METHODS: We randomly assigned a convenience sample of 15 parents and their 17 adolescent children to menu-planning workshops taught by either an adult or peer leader. We conducted process evaluation using workshop observations and participant perceptions. Parents and their adolescents completed questionnaires before and immediately after attending and 3- and 6-months after the workshop. Questionnaires measured menu-planning-related knowledge, self-efficacy and program strategy use. RESULTS: We observed adult and peer leaders completing the majority (≥ 80%) of program tasks well. Participants had positive perceptions of the workshop. Menu-planning-related self-efficacy significantly increased for parents and their adolescents from baseline to all follow-up assessment intervals. CONCLUSIONS: Adult and peer leaders may feasibly teach a menu-planning workshop to parents and adolescent children. Additional outcomes provide limited but promising indications that menu-planning-related self-efficacy increases after workshop participation and remains elevated when assessed 6-months later, regardless of adult or peer leader mode.

RESUMO

OBJECTIVE: To evaluate the feasibility of a grocery store tour for parents and their adolescents being led by adults or adolescent peers. DESIGN: Randomized controlled pilot study with surveys at baseline and post-program, and at 3- and 6-month follow-up. SETTING: Midwestern midsized grocery stores. PARTICIPANTS: Sixty-one parents and their 71 11- to 14-year-old adolescents. INTERVENTION: Nutrition education during 1 90-minute grocery store tour. MAIN OUTCOME MEASURES: Process observations and participants' tour perceptions provided fidelity outcomes. Questionnaires quantitatively assessed participants' knowledge, self-efficacy, and tour strategy use. ANALYSIS: Chi-square and McNemar tests were used to analyze categorical data, and Kruskal-Wallis, Wilcoxon signed-rank, and Mann-Whitney U tests were employed for continuous variables (significance at P < .05). RESULTS: Over 90% of tour tasks were rated as completed well for adult and peer leaders. Participants had positive tour perceptions but noted deficiencies in teen leaders' knowledge and leadership skills. Overall, parents and adolescents retained increased self-efficacy from pre-tour to post-tour intervals. Despite limited knowledge retention, parents reported they had increased (6.5 ± 4.19) healthful grocery shopping behaviors in the 6 months after the intervention. CONCLUSIONS AND IMPLICATIONS: Peers may feasibly lead grocery store tours but they may need additional resources and support to be highly effective.

RESUMO

OBJECTIVES: To inform future initiatives to encourage vegetable intake, we explored how spice and herb (S/H) use with vegetables was related to consumer characteristics. METHODS: A questionnaire collected information on S/H liking and use frequency, whether S/Hs were used when cooking vegetables, and belief that consumers could use S/Hs when cooking vegetables. The questionnaire was distributed to members of an online panel of US consumers. RESULTS: Younger respondents (18-29 years) and respondents who identified as Asian/ Pacific Islander or other racial group used 19 of the 20 S/Hs more frequently than their older and white/Caucasian, African-American or Hispanic counterparts, respectively. S/H use when cooking vegetables at home was significantly higher for women. Self-efficacy was higher for women, 18-29 year-olds, and 30-49 year-olds, and lower for respondents who identified as white/Caucasian race and those with annual incomes below 50,000. CONCLUSIONS: Low-income, male, older ( 50 years), and white/ Caucasian respondents were identified as target audiences that may benefit the most from interventions encouraging S/H use with vegetables to increase consumption. It is critical to account for socio-demographic characteristics of the audience when designing interventions.
