Hoosier Sport: a research protocol for a multilevel physical activity-based intervention in rural Indiana.

Introduction: Currently, only 1 in 4 children in the U.S. engage in the recommended amount of physical activity (PA) and disparities in PA participation increase as income inequities increase. Moreover, leading health organizations have identified rural health as a critical area of need for programming, research, and policy. Thus, there is a critical need for the development and testing of evidence-based PA interventions that have the potential to be scalable to improve health disparities in children from under-resourced rural backgrounds. As such, the present study utilizes human-centered design, a technique that puts community stakeholders at the center of the intervention development process, to increase our specific understanding about how the PA-based needs of children from rural communities manifest themselves in context, at the level of detail needed to make intervention design decisions. The present study connects the first two stages of the NIH Stage Model for Behavioral Intervention Development with a promising conceptual foundation and potentially sustainable college student mentor implementation strategy. Methods: We will conduct a three-phase study utilizing human-centered community-based participatory research (CBPR) in three aims: (Aim 1) conduct a CBPR needs assessment with middle school students, parents, and teachers/administrators to identify perceptions, attributes, barriers, and facilitators of PA that are responsive to the community context and preferences; (Aim 2) co-design with children and adults to develop a prototype multi-level PA intervention protocol called Hoosier Sport; (Aim 3) assess Hoosier Sport's trial- and intervention-related feasibility indicators. The conceptual foundation of this study is built on three complementary theoretical elements: (1) Basic Psychological Needs mini-theory within Self-Determination Theory; (2) the Biopsychosocial Model; and (3) the multilevel Research Framework from the National Institute on Minority Health and Health Disparities. Discussion: Our CBPR protocol takes a human-centered approach to integrating the first two stages of the NIH Stage Model with a potentially sustainable college student mentor implementation strategy. This multidisciplinary approach can be used by researchers pursuing multilevel PA-based intervention development for children.

Awareness of the Fruits and Veggies-More Matters campaign, knowledge of the fruit and vegetable recommendation, and fruit and vegetable intake of adults in the 2007 Food Attitudes and Behaviors (FAB) Survey.

Increased consumption of fruits and vegetables is recommended to reduce chronic disease risk. Few studies have examined awareness of the current fruit and vegetable campaign in the United States, Fruits and Veggies-More Matters. This study assessed awareness of the Fruits and Veggies-More Matters campaign and knowledge of the 7-13 serving recommendation for fruit and vegetable consumption among adults, and determined whether these were associated with fruit and vegetable intake. Cross-sectional data from 3021 adults in the United States' National Cancer Institute's 2007 Food Attitudes and Behaviors Survey were analyzed. Few participants were aware of the Fruits and Veggies-More Matters campaign (2%) and the 7-13 recommendation (6%) for adults. More participants were aware of the former 5 A Day campaign (29%) and recommendation (30%). Thirty-nine percent reported consuming ≥5 servings of fruits and vegetables daily. Participants were more likely to consume ≥5 servings of fruits and vegetables/day if they were aware of the 5 A Day/Fruits and Veggies-More Matters campaign, and reported that the recommendation for adults was ≥5 servings/day. Findings suggest the need to increase awareness of the Fruits and Veggies-More Matters campaign, and the 7-13 recommendation among adults to support high fruit and vegetable intake.

Dietary intakes of preschool-aged children in relation to caregivers' race/ethnicity, acculturation, and demographic characteristics: results from the 2007 California Health Interview Survey.

Few studies have examined the influence of acculturation on dietary behaviors of young children while controlling for other demographic variables. The purpose of this study was to assess reported dietary intakes of preschool-aged children (3-5 years) and subsequent associations with caregivers' race/ethnicity, acculturation and demographic characteristics, using data from the 2007 California Health Interview Survey (CHIS). Analysis was restricted to Hispanic and non-Hispanic white caregivers and their preschool-aged children (n = 1,105). Caregivers' acculturation was assessed using place of birth, duration of United States residence, and language spoken at home. Proxy-reports by caregivers to a dietary screener were used to estimate children's intakes of fruit, 100% fruit juice, vegetables, sweets, and sugar-sweetened beverages consumed. In multivariate analyses, Hispanic caregivers reported their children consumed fewer servings of vegetables than did the children of non-Hispanic white caregivers; there were no other statistically significant differences in children's dietary intakes by caregivers' race/ethnicity. Caregivers' acculturation was associated with caregiver-reported consumption of sweets by children (ß = 0.09, 95%CI = 0.01-0.18). Demographic characteristics that were associated with reported dietary intakes of children included caregivers' age, education, and geographic region of residence. In contrast to past studies of acculturation and diet in older children and adults, this study suggests that for 3-5 year olds, caregivers' level of acculturation does not play as strong a role in the dietary intakes of the younger children under their care.

Fruit and vegetable intake of US adults: comparing intake by mode of survey administration.

Modes for collecting dietary data vary across studies and include in-person/interviewer-administered surveys, mail, and telephone surveys. Few studies use mixed modes to assess dietary intakes. Using data from the 2007 Health Information National Trends Survey, we compared fruit and vegetable intake of adults measured through dual modes (mail and random-digit dial [RDD] telephone), and discussed potential factors that could account for mode differences. The Health Information National Trends Survey data were collected through mailed (n=3,582), and RDD (n=4,092) surveys from December 2007 to May 2008. Data were weighted and analyzed in SUDAAN. Unadjusted mean fruit and vegetable intake was 0.48 servings higher (P<0.001) among mail (mean 5.40) vs RDD (mean 4.09) participants. In a multivariate model that controlled for other predictors, the odds of consuming ≥5 servings of fruit and vegetables per day was 83% higher among mail respondents compared to RDD (odds ratio 1.83, 95% confidence interval 1.62 to 2.07). Other predictors of fruit and vegetable intake were sex, education, participation in physical activity, self-rated health, and knowledge of the fruit and vegetable recommendation. Methodologic issues may account for modal differences in fruit and vegetable intake. Different measures (cups, servings) were used to assess fruit and vegetable intake in both modes, details about portion sizes were provided on the mail mode vs RDD, and closed-ended responses were provided on the mail vs open-ended responses for RDD. We cannot recommend one mode over the other nor attribute mode differences to real differences in reported fruit and vegetable intake between participants from both modes. Future research that uses dual modes needs to use identical methods of dietary assessment to minimize these potential sources of error. Further research is needed to validate the use of dual modes to assess dietary intake and inform research practice.
