Do sugar warning labels influence parents' selection of a labeled snack for their children? A randomized trial in a virtual convenience store.

Despite growing evidence that warning labels reduce purchases of sugary drinks, less is known about warnings' impact on purchases of sugary snacks. This paper aimed to experimentally test whether a front-of-package label warning about high sugar content ("sugar warning label") would reduce parents' likelihood of selecting a labeled snack versus a non-labeled snack for their child in a food store setting. Participants (n = 2,219 parents of at least one child aged 1-5y) were recruited via an online panel and asked to complete a shopping task in a virtual convenience store. Participants were randomized to one of three labeling conditions: barcode control, text-only sugar warning label, or pictorial sugar warning label. Participants viewed two granola snacks, one labeled and one unlabeled, and selected one for purchase. A post-shopping survey measured secondary outcomes. Predictions and analyses were preregistered on www.clinicaltrials.gov (NCT04381481). Participants exposed to the text or pictorial sugar warning labels were less likely to select the labeled snack than those in the barcode control group (21%, 18%, and 34% respectively; p < 0.001 for both comparisons of warning to control). Relative to the barcode control label, the text and pictorial sugar warning labels resulted in greater attention, anticipated social interactions, negative affect, cognitive elaboration, and perceived message effectiveness, as well as lower perceptions of healthfulness, appeal, and intentions to purchase or consume the product (p < 0.001 for all comparisons of warnings to control). There were no differences in outcomes between text and pictorial sugar warning labels. In conclusion, text and pictorial sugar warning labels reduced parents' likelihood of selecting a labeled granola snack for their children. These results contribute to a growing body of evidence showing that warning labels influence food purchasing behaviors.

Nutrition-related claims lead parents to choose less healthy drinks for young children: a randomized trial in a virtual convenience store.

BACKGROUND: Consumption of sugar-sweetened beverages, including fruit drinks (i.e., fruit-flavored drinks containing added sugar), contributes to childhood obesity. OBJECTIVES: We aimed to examine whether nutrition-related claims on fruit drinks influence purchasing among parents and lead to misperceptions of healthfulness. METHODS: We conducted an experiment in a virtual convenience store with 2219 parents of children ages 1-5 y. Parents were randomly assigned to view fruit drinks displaying 1 of 3 claims ("No artificial sweeteners," "100% Vitamin C," and "100% All Natural") or no claim (i.e., control group). Parents selected among each of 2 drinks for their young child: 1) a fruit drink or 100% juice (primary outcome), and 2) a fruit drink or water. RESULTS: When choosing between a fruit drink and 100% juice, 45% of parents who viewed the fruit drink with the "No artificial sweeteners" claim, 51% who viewed the "100% Vitamin C" claim, and 54% who viewed the "100% All Natural" claim selected the fruit drink, compared with 32% in the no-claim control group (all P < 0.001). "No artificial sweeteners" (Cohen's d = 0.13, P < 0.05) and "100% All Natural" (d = 0.15, P < 0.05) claims increased the likelihood of parents choosing the fruit drink instead of water but "100% Vitamin C" did not (P = 0.06). All claims made parents more likely to incorrectly believe that the fruit drinks contained no added sugar and were 100% juice than the control (d ranged from 0.26 to 0.84, all P < 0.001), as assessed in a posttest survey. The impact of claims on selection of the fruit drink (compared with 100% juice) did not vary by any of the moderators examined (e.g., race/ethnicity, income; all moderation P > 0.05). CONCLUSIONS: Nutrition-related claims led parents to choose less healthy beverages for their children and misled them about the healthfulness of fruit drinks. Labeling regulations could mitigate misleading marketing of fruit drinks.This trial was registered at clinicaltrials.gov as NCT04381481.

Food Skills Education and Low-Income Adults' Healthy Food Choices.

BACKGROUND: The Cooking Matters food skills education program equips low-income families with the skills and knowledge to shop for and cook healthy meals within budget and time constraints. AIMS: To explore whether participation in Cooking Matters is associated with healthier food choices using a 6-item scale, comprised of a variety of food categories. METHODS: Cooking Matters participants (n = 332) and a comparison group (n = 336) completed surveys at baseline, 3-, and 6-month follow-up. RESULTS: Cooking Matters participants experienced greater improvements in healthy choices overall (p < 0.0001) and for each of the six underlying items at 3 month follow-up. Improvements were sustained at 6-month follow-up overall and for all categories, except low-fat milk (p = 0.1168). DISCUSSION: Participation in Cooking Matters was associated with improvements in overall healthy food choices across a variety of food groups and maintained at 6-month follow-up. Enabling healthy food choices is an important step toward improved diet quality.

Lessons From the Feasibility Testing of a Parent-Focused, Life Skills-Based Intervention to Prevent Obesity in Preschoolers From Underserved Families.

This article describes lessons from the feasibility testing of a parent-focused, life skills-based intervention to promote healthy weight in 58 low-income children aged 2 to 5 years. This intervention was feasible and acceptable, with a potential to impact child weight and diet (calories) and parental quality of life (QOL). The group delivery approach through a partnering organization (Head Start) was a more efficient way to reach/engage parents. Compared with one-on-one sessions, the group could provide an avenue to enhance parental psychosocial well-being, given QOL improvements among parents in group sessions. Lessons will inform future research to test the effectiveness of life skills interventions.

Evaluation of an Electronic Health Record Referral Process to Enhance Participation in Evidence-Based Arthritis Interventions.

PURPOSE AND OBJECTIVES: Effective community-based programs to manage arthritis exist, but many adults with arthritis are unaware that these programs are available in their communities. An electronic health record (EHR) referral intervention was designed to strengthen health care and community-based partnerships and increase participation in these arthritis programs. The intervention was developed in response to a national effort that aimed to enhance the health, wellness, and quality of life for people with arthritis by increasing the awareness and availability of, and participation in arthritis-appropriate evidence-based interventions. INTERVENTION APPROACH: The National Recreation and Park Association recruited 4 park and recreation agencies and their health care partners to implement an EHR-based retrospective and point-of-care referral intervention. Eligible for referral were adults aged 45 or older with an arthritis condition who were seen by a physician within the past 18 months, and were living within the park and recreation service area. After health care organizations identified eligible adults, they either mailed communication packages describing the availability and benefits of the intervention and conducted phone calls to encourage arthritis-appropriate intervention participation or counseled and referred patients during an office visit. EVALUATION METHODS: The pilot was assessed by using semi-structured interviews with key intervention staff members and the Consolidated Framework for Implementation Research. RESULTS: Our approach resulted in referrals for 3,660 people, 1,063 (29%) of whom participated in an intervention. Analysis of key informant interviews also highlighted the specific contextual factors, facilitators, and barriers that influenced the adaptation and overall implementation of the referral intervention. IMPLICATIONS FOR PUBLIC HEALTH: Our pilot demonstrates that successful coordination between health care organizations and community-based organizations can promote awareness of and participation in community-based programs. An understanding of the contextual factors and lessons learned can be used to inform processes that can lead to more effective and sustainable health care and community-based partnerships.

Foods for Health: An Integrated Social Medical Approach to Food Insecurity Among Patients With Diabetes.

PURPOSE: Examine a clinic-based approach to improve food security and glycemic control among patients with diabetes. DESIGN: One-group repeated-measures design. SETTING: Federally Qualified Health Centers in a large Midwest city. SAMPLE: Of the 933 patients with diabetes who consented at baseline, 398 (42.66%) returned during the follow-up period for a visit that included Hemoglobin A1c (HbA1c) results. INTERVENTION: Integrated social medicine approach that includes food insecurity screening, nutrition education, and assistance accessing food resources as a standard-of-care practice designed to minimize disruptions in how patients and providers experience medical care. MEASURES: HbA1c collected as part of a standard blood panel. ANALYSIS: Repeated-measure, mixed-effect linear regression models. RESULTS: There was a decrease in mean HbA1c (Δ = -0.22, P = 0.01) over the study period. The model examining change over time, glycemic control (GC), and food security status (F1, 352 = 5.80, P = 0.02) indicated that among participants with poor GC (33.12%), food secure (FS) participants exhibited significantly greater levels of improvement than food insecure (FI) participants (Δ = -0.55, P = 0.04). Among participants with good GC, changes in HbA1c were not significantly different between FS and FI participants (Δ = 0.23, P = 0.21). CONCLUSION: Providing nutrition education and food assistance improved HbA1c profiles among FS and FI participants, but FI participants may face social and structural challenges that require additional support from health care teams.

Low-Income Parents' Use of Front-of-Package Nutrition Labels in a Virtual Supermarket.

OBJECTIVE: To examine the impact front-of-package nutrition labels (FOPLs) have on decision-making abilities among low-income parents in a virtual supermarket. DESIGN: A 4-by-2 experimental design with 3 FOPLs (summary, nutrient-specific, hybrid) and a no-FOPL comparison. Within the FOPL condition, participants either shopped with a time limit (10 minutes) or with no time limit. SETTING: A web-based, 3-dimensional virtual supermarket. PARTICIPANTS: Parents (n = 1,452) from low-income households with at least 1 child aged 4-12 years. MAIN OUTCOMES MEASURED: Index derived from the United Kingdom's Nutrient Profiling Model that summarized the overall nutrient profile of the participant's shopping basket. ANALYSIS: Analysis of covariance with post hoc estimations (pairwise) of condition means adjusted for multiple comparisons. RESULTS: All FOPLs led to healthier nutrient profiles than the no-FOPL condition (P < .001). Simple FOPLs (ie, summary, hybrid) led to healthier nutrient profiles than nutrient-specific FOPLs (P = .02 and P < .001, respectively). Among parents exposed to simple FOPLs, those under time pressure made less healthy choices than those who were not under time pressure (P = .05 and P = .03, respectively). Time pressure did not affect parents exposed to nutrient-specific FOPLs (P = .69). CONCLUSIONS AND IMPLICATIONS: Front-of-package nutrition labels can aid parents in selecting healthier products. Simple FOPLs provide greater utility for selecting healthier products than FOPLs that present an array of nutrient information. Time pressure can influence how parents interact with different types of label information.

Perceived Advantages and Disadvantages of Online Grocery Shopping among Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) Participants in Eastern North Carolina.

This study's purpose was to qualitatively examine perceived advantages and disadvantages of online grocery shopping among participants (n = 7) in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). Initial in-depth, qualitative interviews were conducted, after which participants completed an episode of online grocery shopping, picked up the online order at the store, and completed an in-store shopping episode and a follow-up in-depth interview. Interviews were audio-recorded, transcribed verbatim, and analyzed deductively. Participants stated that in-store impulse purchases occurred at the check-out and cookie aisles and included chips and candy, but sometimes healthier foods such as fruit. Advantages of online grocery shopping included ease, convenience, and saving time. Disadvantages included inadequate substitutions, the online shopping fee, lack of control over selection of perishable goods, and inability to find good deals online versus in the store. Further research is needed to determine how to encourage healthy grocery purchases online.

Online grocery shopping: promise and pitfalls for healthier food and beverage purchases.

OBJECTIVES: (i) To determine the current state of online grocery shopping, including individuals' motivations for shopping for groceries online and types of foods purchased; and (ii) to identify the potential promise and pitfalls that online grocery shopping may offer in relation to food and beverage purchases. DESIGN: PubMed, ABI/INFORM and Google Scholar were searched to identify published research. SETTING: To be included, studies must have been published between 2007 and 2017 in English, based in the USA or Europe (including the UK), and focused on: (i) motivations for online grocery shopping; (ii) the cognitive/psychosocial domain; and (iii) the community or neighbourhood food environment domain. SUBJECTS: Our search yielded twenty-four relevant papers. RESULTS: Findings indicate that online grocery shopping can be a double-edged sword. While it has the potential to increase healthy choices via reduced unhealthy impulse purchases, nutrition labelling strategies, and as a method to overcome food access limitations among individuals with limited access to a brick-and-mortar store, it also has the potential to increase unhealthy choices due to reasons such as consumers' hesitance to purchase fresh produce online. CONCLUSIONS: Additional research is needed to determine the most effective ways to positively engage customers to use online grocery shopping to make healthier choices.

Interrater Reliability of a Field-Based Preschool Movement Skills Assessment.

OBJECTIVE: To determine the interrater reliability of the Preschool Movement Assessment (PMA), a unique field-based assessment tool for use by early childhood professionals in preschool settings. METHODS: A total of 123 preschool children, aged 3-5years, were assessed by 6 trained raters using the PMA tool in an intervention. Interrater agreement on individual items of the PMA was determined using the kappa (κ) and intraclass correlation coefficient statistics. RESULTS: Weighted κ values were 0.82-0.96, indicating excellent agreement for all constructs of the PMA. The 95% confidence intervals indicated that all weighted κ's were statistically significant. The intraclass correlation coefficient for the PMA total score was 0.97. CONCLUSIONS AND IMPLICATIONS: After additional developmental research, the tool might serve to establish and support a minimum level of functional movements that should be attained before a child enters grade school.

School health implementation tools: a mixed methods evaluation of factors influencing their use.

BACKGROUND: The U.S. Centers for Disease Control and Prevention (CDC) develops tools to support implementation of evidence-based interventions for school health. To advance understanding of factors influencing the use of these implementation tools, we conducted an evaluation of state, school district, and local school staffs' use of four CDC tools to support implementation of physical activity, nutrition, health education, and parent engagement. Two frameworks guided the evaluation: Interactive Systems Framework (ISF) for Dissemination and Implementation and Consolidated Framework for Implementation Research (CFIR). METHODS: The evaluation applied a mixed methods, cross-sectional design that included online surveys (n = 69 state staff from 43 states), phone interviews (n = 13 state staff from 6 states), and in-person interviews (n = 90 district and school staff from 8 districts in 5 states). Descriptive analyses were applied to surveys and content analysis to interviews. RESULTS: The survey found that the majority of state staff surveyed was aware of three of the CDC tools but most were knowledgeable and confident in their ability to use only two. These same two tools were the ones for which states were most likely to have provided training and technical assistance in the past year. Interviews provided insight into how tools were used and why use varied, with themes organized within the ISF domain "support strategies" (e.g., training, technical assistance) and four CFIR domains: (1) characteristics of tools, (2) inner setting, (3) outer setting, and (4) individuals. Overall, tools were valued for the credibility of their source (CDC) and evidence strength and quality. Respondents reported that tools were too complex for use by school staff. However, if tools were adaptable and compatible with inner and outer setting factors, state and district staff were willing and able to adapt tools for school use. CONCLUSIONS: Implementation tools are essential to supporting broad-scale implementation of evidence-based interventions. This study illustrates how CFIR and ISF might be applied to evaluate factors influencing tools' use and provides recommendations for designing tools to fit within the multi-tiered systems involved in promoting, supporting, and implementing evidence-based interventions in schools. Findings have relevance for the design of implementation tools for use by other multi-tiered systems.

Cooking Matters for Adults Improves Food Resource Management Skills and Self-confidence Among Low-Income Participants.

OBJECTIVE: Determine the impact of Cooking Matters for Adults (CM) on food resource management (FRM) skills and self-confidence 6 months after course completion. DESIGN: Quasi-experimental design with nonequivalent comparison group and 6-month follow-up. SETTING: Cooking Matters for Adults programs in CA, CO, ME, MA, MI, and OR. PARTICIPANTS: Participants in CM attending classes in April to July, 2016 (n = 332); comparison group (n = 336). INTERVENTION: Cooking Matters for Adults educated low-income adults to shop for and prepare healthy meals economically using hands-on meal preparation, facilitated discussion, and an interactive grocery store tour. Classes met for 2 hours, once a week for 6 weeks. MAIN OUTCOME MEASURE(S): Food resource management practices; FRM self-confidence (ie, in shopping for and preparing healthy foods on a budget); worrying that food might run out. ANALYSIS: Pearson's chi-square test and t tests identified measures associated with outcomes of interest and between-group differences. Repeated-measures linear mixed models with fixed and random effects were used to examine differences in outcomes between participants in CM and nonequivalent comparison group and to estimate the treatment effect of the program at 3 and 6 months after course completion. RESULTS: Six months after course completion, CM participants demonstrated improvements in all outcome measures of interest: Use of FRM practices improved (P = .002) as did FRM confidence (P < .001). Participants also worried less that food would run out before they had money to buy more (P = .03). CONCLUSIONS AND IMPLICATIONS: This study demonstrated a positive impact of including FRM skills and confidence building in a nutrition education program, the effects of which could be seen for 6 months after participation in the program. Equipping low-income families with FRM skills allowed them to access healthier foods even during times of hardship.

Developing a Tool to Assess the Capacity of Out-of-School Time Program Providers to Implement Policy, Systems, and Environmental Change.

BACKGROUND: Little is known about public health practitioners' capacity to change policies, systems, or environments (PSEs), in part due to the absence of measures. To address this need, we partnered with the Alliance for a Healthier Generation (Alliance) to develop and test a theory-derived measure of the capacity of out-of-school time program providers to improve students' level of nutrition and physical activity through changes in PSEs. COMMUNITY CONTEXT: The measure was developed and tested through an engaged partnership with staff working on the Alliance's Healthy Out-of-School Time (HOST) Initiative. In total, approximately 2,000 sites nationwide are engaged in the HOST Initiative, which serves predominantly high-need children and youths. METHODS: We partnered with the Alliance to conduct formative work that would help develop a survey that assessed attitudes/beliefs, social norms, external resources/supports, and self-efficacy. The survey was administered to providers of out-of-school time programs who were implementing the Alliance's HOST Initiative. OUTCOME: Survey respondents were 185 out-of-school time program providers (53% response rate). Exploratory factor analysis yielded a 4-factor model that explained 44.7% of the variance. Factors pertained to perceptions of social norms (6 items) and self-efficacy to build support and engage a team (4 items) and create (5 items) and implement (3 items) an action plan. INTERPRETATION: We report initial development and factor analysis of a tool that the Alliance can use to assess the capacity of after-school time program providers, which is critical to targeting capacity-building interventions and assessing their effectiveness. Study findings also will inform the development of measures to assess individual capacity to plan and implement other PSE interventions.

Adding a Social Marketing Campaign to a School-Based Nutrition Education Program Improves Children's Dietary Intake: A Quasi-Experimental Study.

BACKGROUND: Evidence supports the use of social marketing campaigns to improve nutrition knowledge and reinforce the effects of nutrition education programs. However, the additional effects of parent-focused social marketing with nutrition education have received little attention. OBJECTIVE: Our aim was to assess the impact of the Iowa Nutrition Network's school-based nutrition education program (Building and Strengthening Iowa Community Support for Nutrition and Physical Activity [BASICS]) and the benefits of adding a multichannel social marketing intervention (BASICS Plus) to increase parent-directed communication. DESIGN AND INTERVENTION: A quasi-experimental design with three study conditions compared a school-based nutrition education program (BASICS) with a school-based and social marketing intervention (BASICS Plus) and a no-treatment comparison group. PARTICIPANTS/SETTING: The study included 1,037 third-grade students attending 33 elementary schools and their parents. MAIN OUTCOME MEASURES: Measures included parents' reports of their children's in-home consumption of fruits and vegetables (F/V) and use of low-fat/fat-free milk. Data on F/V were collected using a modified version of the University of California Cooperative Extension Food Behavior Checklist; and data on milk use were collected using two questions from the National Health and Nutrition Examination Survey. STATISTICAL ANALYSES: Multilevel, mixed-effect regression models that account for correlation within repeated measures and children within school were used to compare the mean change over time in the outcome variable for one study group with the mean change over time for another study group. RESULTS: Children in BASICS increased mean consumption of fruit by 0.16 cups (P=0.04) compared with children in the comparison group. Children in BASICS Plus increased mean consumption of fruit by 0.17 cups (P=0.03) and mean consumption of vegetables by 0.13 cups (P=0.02). Children in BASICS Plus were 1.3 times (P=0.05) more likely to use low-fat/fat-free milk than children in either the BASICS group or the comparison group. CONCLUSIONS: Gaining parents' attention and engaging them in healthy eating practices for their children can be a useful way to increase the effectiveness of school-based nutrition education programs. This study demonstrates the benefits of incorporating a parent-focused social marketing campaign in nutrition education interventions.

Eat Smart, Live Strong intervention increases fruit and vegetable consumption among low-income older adults.

This study evaluated the impact of a four-session interactive nutrition education program-Eat Smart, Live Strong (ESLS)-on the consumption of fruit and vegetables by low-income older adults. A pre-post quasi-experimental design study was conducted with a longitudinal sample of 614 low-income Supplemental Nutrition Assistance Program (SNAP) participants and those eligible for SNAP, aged 60 to 80 years, in 17 intervention and 16 comparison senior centers in Michigan. The study compared participants' self-reports of their consumption of fruit and vegetables using a modified version of the University of California Cooperative Extension Food Behavior Checklist. ESLS increased participants' average daily consumption of fruit by 0.2 cups (P < 0.05) and vegetables by 0.31 cups (P < 0.01). ESLS, a four-session, cognitive-behavioral nutrition education program is an effective curriculum for helping low-income older adults eat more fruit and vegetables.

The relationship between amount of soda consumed and intention to reduce soda consumption among adults exposed to the Choose Health LA 'Sugar Pack' health marketing campaign.

OBJECTIVE: To examine behavioural intention to reduce soda consumption after exposure to the Choose Health LA 'Sugar Pack' campaign in Los Angeles County, California, USA. DESIGN: A cross-sectional street-intercept survey was conducted to assess knowledge, attitudes, health behaviours and behavioural intentions after exposure to the 'Sugar Pack' campaign. A multivariable regression analysis was performed to examine the relationships between the amount of soda consumed and self-reported intention to reduce consumption of non-diet soda among adults who saw the campaign. SETTING: Three pre-selected Los Angeles County Metro bus shelters and/or rail stops with the highest number of 'Sugar Pack' campaign advertisement placements. SUBJECTS: Riders of the region's Metro buses and railways who were the intended audience of the campaign advertisements. RESULTS: The overall survey response rate was 56 % (resulting n 1041). Almost 60 % of respondents were exposed to the advertisements (619/1041). The multivariable logistic regression analysis suggested that the odds of reporting intention to reduce soda consumption among moderate consumers (1-6 sodas/week) were 1·95 times greater than among heavy consumers (≥1 soda/d), after controlling for clustering and covariates. Respondents with less than a high-school education and who perceived sugary beverage consumption as harmful also had higher odds; in contrast, respondents aged ≥65 years had lower odds. CONCLUSIONS: Results suggest that future campaigns should be tailored differently for moderate v. heavy consumers of soda. Similar tailoring strategies are likely needed for younger groups, for those with less educational attainment and for those who do not perceive consumption of soda as harmful.

Evaluating the Impact of Six Supplemental Nutrition Assistance Program Education Interventions on Children's At-Home Diets.

BACKGROUND: Nutrition education in the Supplemental Nutrition Assistance Program Education (SNAP-Ed) is designed to promote healthy eating behaviors in a low-income target population. PURPOSE: To evaluate the effectiveness of six SNAP-Ed interventions delivered in child care centers or elementary school settings in increasing participating children's at-home fruit and vegetable (F/V) consumption by 0.3 cups per day and use of fat-free or low-fat milk instead of whole or reduced-fat milk during the prior week. METHOD: Clustered randomized or quasi-experimental clustered trials took place in child care centers or elementary schools between 2010 and 2012. Parents of children at intervention and control sites completed baseline and follow-up surveys about their child's at home F/V consumption and other dietary behaviors. RESULTS: One of the six interventions was successful in meeting the objective of increasing children's F/V consumption by 0.3 cups per day. For three of the six interventions, there was a small but statistically significant increase in F/V consumption and/or use of low-fat or fat-free milk. CONCLUSION: Although not all interventions were effective, these findings suggest that it is possible for some SNAP-Ed interventions to improve dietary habits among low-income children among some families. The effective interventions appear to have benefited from implementation experience and sustained efforts at intervention refinement and improvement.

Nutrition-education program improves preschoolers' at-home diet: a group randomized trial.

OBJECTIVE: This study evaluated whether a nutrition-education program in child-care centers improved children's at-home daily consumption of fruits and vegetables, at-home use of low-fat/fat-free milk, and other at-home dietary behaviors. MATERIALS AND METHODS: Twenty-four child-care centers serving low-income families were matched by region, type, and size, and then randomly assigned to either an intervention or control condition. In the 12 intervention centers, registered dietitian nutritionists provided nutrition education to children and parents separately during a 6- to 10-week period. They also held two training sessions for center staff, to educate them on healthy eating and physical activity policies at the centers, and distributed weekly parent newsletters that included activities and recipes. Parents (n=1,143) completed a mail or telephone survey at baseline and follow-up to report information on their child's fruit, vegetable, and milk consumption and other dietary behaviors at home. This study used general and generalized linear mixed models to evaluate program impacts, while accounting for the clustering of children within centers. This study included child age, child sex, household size, respondent race/ethnicity, respondent age, and respondent sex as covariates. RESULTS: The program had a substantial impact on children's at-home daily consumption of vegetables and use of low-fat/fat-free milk. This study also found a significant increase in the frequency of child-initiated vegetable snacking, which might have contributed to the significant increase in vegetable consumption. The program did not have a significant impact on fruit consumption or parental offerings of fruits and vegetables, child-initiated fruit snacking, or child fruit consumption. CONCLUSIONS: This intervention in child-care settings that emphasized children, parents, and teachers significantly increased at-home vegetable and low-fat/fat-free milk consumption among low-income preschoolers.

Repeated exposure to media messages encouraging parent-child communication about sex: differential trajectories for mothers and fathers.

PURPOSE: To examine changes in parent-child communication related to sexual behavior after exposure to public health messages. DESIGN: Randomized, controlled trial that was part of precampaign message testing. SETTING: Exposure occurred online or through DVDs mailed to participants and viewed on their personal computers. Data collection occurred via a secure Web site. PATIENTS: Participants included parents (n  =  1969) living with a child age 10 to 14 years drawn from a nationally representative sample of U.S. households. INTERVENTION: Treatment participants were exposed to video, audio, and print advertisements that promoted the benefits of speaking to their children early and often about delaying initiation of sexual activity; messages also directed parents to an informational Web site. MEASURES: The dependent variable assessed frequency of parent-child communication related to sexual behavior. The primary independent variable was treatment assignment. ANALYSIS: Longitudinal growth modeling that included five waves of data. RESULTS: The trajectory of growth over time differed between fathers in the treatment group and fathers in the control group (F[1, 2357]  =  4.15; p < .042), indicating more frequent communication among treatment fathers than among control fathers. Trajectories did not differ between mothers in treatment and control groups. CONCLUSION: This study demonstrates that father-child and mother-child communication patterns differ over time in response to public health messages. Findings have implication for researchers developing health marketing campaigns.

Perceptions of the food shopping environment are associated with greater consumption of fruits and vegetables.

OBJECTIVE: The present study examined whether characteristics such as quality, selection and convenience are associated with dietary intake of fruits and vegetables independent of perceived costs in an inner-city, low-income population. DESIGN: Secondary analysis of baseline data from a social marketing intervention designed to change household dietary practices among parents of 3- to 7-year-old children. SETTING: A community sample drawn from six low-income, primarily minority neighbourhoods in Chicago, IL, USA. SUBJECTS: From the parent study, 526 respondents completed the baseline survey and were eligible for inclusion. Of this number, 495 provided complete data on sociodemographic characteristics, fruit and vegetable consumption, perceptions of the shopping environment, perceived costs of fruits and vegetables, and food shopping habits. RESULTS: Logistic regression analysis showed that more positive perceptions of the food shopping environment were associated with greater consumption of fruits and vegetables. There was an increase of approximately twofold in the likelihood of consuming three or more fruits and vegetables daily per level of satisfaction ascribed to the shopping environment. This association was independent of perceived cost, store type and sociodemographic characteristics. CONCLUSIONS: Our data show that among a generally minority and low-income population, quality, selection and convenience are important determinants of fruit and vegetable consumption. Nutrition promotion campaigns that aim to alter the built environment by increasing access to fruits and vegetables should recognize that simply increasing availability may not yield beneficial change when characteristics of the shopping context are ignored.
