Communities Partnering With Researchers: An Evaluation of Coalition Function in a Community-Engaged Research Approach.

BACKGROUND: Community coalitions are frequently used as partners for community-engaged research. However, limited research shows how these partnerships affect the coalitions. OBJECTIVE: To evaluate the effects of researcher-coalition collaboration on coalition function in the pilot year of a 4-year intervention program targeting childhood obesity in rural, low-income communities. METHODS: A quasi-experimental study using a quantitative survey (Coalition Self-Assessment Survey [CSAS]) evaluated factors related to coalition function and efficacy. Twelve community coalitions from seven states completed survey evaluations at baseline (n = 133), and at the 1-year follow-up (n = 113). Pearson's χ2 and Mann-Whitney U tests were computed; significance was set at p < .05. RESULTS: Survey results revealed significant changes for coalitions engaged in research partnership. Institutional engagement with community health coalitions in the first year of partnership was related to enhanced coalition function. CONCLUSIONS: Coalitions with a greater degree of researcher collaboration may be more successful in addressing community health problems.

A quasi-experimental study to mobilize rural low-income communities to assess and improve the ecological environment to prevent childhood obesity.

BACKGROUND: The Ecological Model of Childhood Overweight focuses on characteristics that could affect a child's weight status in relation to the multiple environments surrounding that child. A community coaching approach allows community groups to identify their own strengths, priorities and identity. Little to no research currently exists related to community-based efforts inclusive of community coaching in creating environmental change to prevent childhood obesity particularly in rural communities. METHODS: A quasi-experimental study will be conducted with low-income, rural communities (n = 14) in the North Central region of the United States to mobilize capacity in communities to create and sustain an environment of healthy eating and physical activity to prevent childhood obesity. Two rural communities within seven Midwestern states (IN, KS, MI, OH, ND, SD, WI) will be randomly assigned to serve as an intervention or comparison community. Coalitions will complete assessments of their communities, choose from evidence-based approaches, and implement nutrition and physical activity interventions each year to prevent childhood obesity with emphasis on policy, system or environmental changes over four years. Only intervention coalitions will receive community coaching from a trained coach. Outcomes will be assessed at baseline, annually and project end using previously validated instruments and include coalition self-assessments, parental perceptions regarding the built environment, community, neighborhood, and early childhood environments, self-reflections from coaches and project staff, ripple effect mapping with coalitions and, final interviews of key stakeholders and coaches. A mixed-methods analysis approach will be used to evaluate if Community Coaching enhances community capacity to create and sustain an environment to support healthy eating and physical activity for young children. ANOVA or corresponding non-parametric tests will be used to analyze quantitative data relating to environmental change with significance set at P < .05. Dominant emergent themes from the qualitative data will be weaved together with quantitative data to develop a theoretical model representing how communities were impacted by the project. DISCUSSION: This project will yield data and best practices that could become a model for community development based approaches to preventing childhood obesity in rural communities.

Evaluation of Nutrition and Physical Activity Policies and Practices in Child Care Centers within Rural Communities.

BACKGROUND: Although some researchers have examined nutrition and physical activity policies within urban child care centers, little is known about the potentially unique needs of rural communities. METHODS: Child care centers serving preschool children located within low-income rural communities (n = 29) from seven states (Indiana, Kansas, Michigan, North Dakota, Ohio, South Dakota, and Wisconsin) were assessed to determine current nutrition and physical activity (PA) practices and policies. As part of a large-scale childhood obesity prevention project, the Community Healthy Living Index's previously validated Early Childhood Program Assessment Tool was used to collect data. Descriptive statistical analysis was conducted to identify high-priority areas. Healthy People 2020 and the Academy of Nutrition and Dietetics' recommendations for nutrition and PA policies in child care centers were used as benchmarks. RESULTS: Reports of not fully implementing (<80% of the time) recommended nutrition-related policies or practices within rural early child care centers were identified. Centers not consistently serving a variety of fruits (48%), vegetables (45%), whole grains (41%), limiting saturated fat intake (31%), implementing healthy celebration guidelines (41%), involving children in mealtime (62%), and referring families to nutrition assistance programs (24%) were identified. More than one third of centers also had limited structured PA opportunities. Although eligible, only 48% of the centers participated in the Child and Adult Care Food Program. CONCLUSIONS: Overall, centers lacked parental outreach, staff training, and funding/resources to support nutrition and PA. These results provide insight into where child care centers within low-income, rural communities may need assistance to help prevent childhood obesity.

Vitamin and mineral supplements have a nutritionally significant impact on micronutrient intakes of older adults attending senior centers.

Older adults frequently report use of vitamin and mineral (VM) supplements, although the impact of supplements on dietary adequacy remains largely unknown. The purpose of the current study was to evaluate micronutrient intakes of older adults with emphasis on identifying nutrients most improved by VM supplements, nutrients most likely to remain inadequate, and nutrients most likely consumed in excess. Community-based volunteers were recruited from senior centers and completed a questionnaire querying demographic data, current health status, and VM supplement use. Participants (n = 263) were then contacted by telephone to complete two 24-hour diet recalls and confirm VM supplement use. Dietary adequacy was determined by comparing the ratio of mean dietary intake to the Dietary Reference Intakes (DRI). Dietary consumption was lowest for vitamins D and E, calcium, and magnesium. VM supplementation most improved intakes of vitamins E, D, B(6), folic acid, and calcium. Participants were most likely to exceed the Tolerable Upper Limit with supplementation of niacin, folic acid, and vitamin A.

Trans fats in America: a review of their use, consumption, health implications, and regulation.

Trans fatty acids have long been used in food manufacturing due in part to their melting point at room temperature between saturated and unsaturated fats. However, increasing epidemiologic and biochemical evidence suggest that excessive trans fats in the diet are a significant risk factor for cardiovascular events. A 2% absolute increase in energy intake from trans fat has been associated with a 23% increase in cardiovascular risk. Although Denmark has shown it is possible to all but eliminate commercial sources of trans fats from the diet, total elimination is not possible in a balanced diet due to their natural presence in dairy and meat products. Thus, the American Heart Association recommends limiting trans fats to <1% energy, and the American Dietetic Association, the Institute of Medicine, US Dietary Guidelines, and the National Cholesterol Education Project all recommend limiting dietary trans-fat intake from industrial sources as much as possible. The presence of small amounts of trans fat in hydrogenated or partially hydrogenated oils/food products will likely cause many Americans to exceed their recommended maximum. This likelihood is exacerbated by the Food and Drug Administration labeling rules, which allow products containing <0.5 g trans fat per serving to claim 0 g trans fat. Many products with almost 0.5 g trans fat, if consumed over the course of a day, may approximate or exceed the 2 g maximum as recommended by American Heart Association, all while claiming to be trans-fat free. Accordingly, greater transparency in labeling and/or active consumer education is needed to reduce the cardiovascular risks associated with trans fats.

Food intake of Kansans over 80 years of age attending congregate meal sites.

As the population of the United States continues to age, it has become increasingly more important to recognize the food intake and eating habits of older adults. The objective of this study was to describe the food group intake, factors predicting food group intake, and the food choices of community-dwelling Kansans, 80 years of age and older who participate in congregate meal programs. Participants completed a short questionnaire querying demographic information, current health status, and dietary supplement use. Participants (n = 113) were then followed up via telephone to complete two 24-hour diet recalls. Data were analyzed to determine adequacy of food group intake and mean intake. Regression analyses were used to determine factors predicting intake and frequency analysis established food typically consumed. Female participants were significantly more likely to consume more fruit servings than males. Intake was low for all five of the food groups, especially dairy. Chronic health conditions and dietary supplement use were consistently predictive factors of the amount of each food group consumed.

Food safety educational intervention positively influences college students' food safety attitudes, beliefs, knowledge, and self-reported practices.

In this study, the authors evaluated college students' food safety attitudes, beliefs, knowledge, and self-reported practices and explored whether these variables were positively influenced by educational intervention. Students (n=59), were mostly seniors, health or non-health majors, and responsible for meal preparation. Subjects completed a food safety questionnaire (FSQ) prior to educational intervention, which consisted of three interactive modules. Subjects completed module pre-, post-, and post-posttests. The FSQ was also administered after exposure to intervention and five weeks later to determine changes in food safety attitudes, beliefs, knowledge, and self-reported practices. Students' FSQ attitude scores increased from 114 to 122 (p < or = .001); FSQ belief and knowledge scores improved from 86 to 98 (p < or = .001) and from 11 to 13 (p < or = .001), respectively. Food safety knowledge was also measured by module pre- and posttests, and improved significantly after intervention for all students, with health majors having the greatest increase. Intervention resulted in improved food safety self-reported practices for health majors only. The educational intervention appeared effective in improving food safety beliefs and knowledge. For health majors, attitudes and some self-reported practices improved. For all areas, the strongest effects were seen in health majors.

Calcium-fortified beverage supplementation on body composition in postmenopausal women.

BACKGROUND: We investigated the effects of a calcium-fortified beverage supplemented over 12 months on body composition in postmenopausal women (n = 37, age = 48-75 y). METHODS: Body composition (total-body percent fat, %FatTB; abdominal percent fat, %FatAB) was measured with dual energy x-ray absorptiometry. After baseline assessments, subjects were randomly assigned to a free-living control group (CTL) or the supplement group (1,125 mg Ca++/d, CAL). Dietary intake was assessed with 3-day diet records taken at baseline and 12 months (POST). Physical activity was measured using the Yale Physical Activity Survey. RESULTS: At 12 months, the dietary calcium to protein ratio in the CAL group (32.3 +/- 15.6 mg/g) was greater than the CTL group (15.2 +/- 7.5 mg/g). There were no differences from baseline to POST between groups for changes in body weight (CAL = 0.1 +/- 3.0 kg; CTL = 0.0 +/- 2.9 kg), %FatTB (CAL = 0.0 +/- 2.4%; CTL = 0.5 +/- 5.4%), %FatAB (CAL = -0.4 +/- 8.7%; CTL = 0.6 +/- 8.7%), or fat mass (CAL = 1.3 +/- 2.6 kg; CTL = 1.3 +/- 2.7 kg). CONCLUSION: These results indicate that increasing the calcium to protein ratio over two-fold by consuming a calcium-fortified beverage for 12 months did not decrease body weight, body fat, or abdominal fat composition in postmenopausal women.
