Nutrition and Physical Activity in Child Care. Results from an Environmental Intervention

BACKGROUND With evidence of increased levels of obesity in younger children, the child-care setting is an important intervention target. Few environmental interventions exist, and none target both diet and physical activity. The Nutrition and Physical Activity Self-Assessment for Child Care (NAP SACC) intervention was developed to fill this research and practice gap. DESIGN Randomized controlled. SETTING/PARTICIPANTS Health professionals (child-care health consultants) serving child-care centers in North Carolina were recruited (n=30), randomly assigned into intervention or delayed-intervention control groups, and trained to implement the NAP SACC program. Up to three child-care centers were recruited (n=84) from each consultants existing caseload. INTERVENTION Implemented in 2005, the NAP SACC intervention includes an environmental self-assessment, selection of areas for change, continuing education workshops, targeted technical assistance, and re-evaluation. Implementation occurred over a 6-month period. MAIN OUTCOME MEASURES An observational instrument, Environment and Policy Assessment and Observation (EPAO), provided objective evidence of intervention impact and was completed by trained research staff blinded to study assignment. Data were collected in 2005 and 2006. Statistical analyses were conducted in 2006. RESULTS Intention-to-treat analysis results were nonsignificant. Exploratory analyses using only centers that completed most of the NAP SACC program suggest an intervention effect. CONCLUSIONS Factors in the intervention design, the fidelity of implementation, the selection of outcome measure, or a combination of these may have contributed to the lack of intervention effect observed. Because of this studys use of existing public health infrastructure and its potential for implementation, future studies should address strategies for improving effectiveness.

An instrument to assess the obesogenic environment of child care centers.

OBJECTIVES To describe protocol and interobserver agreements of an instrument to evaluate nutrition and physical activity environments at child care. METHODS Interobserver data were collected from 9 child care centers, through direct observation and document review (17 observer pairs). RESULTS Mean agreement between observer pairs was 87.26% and 79.29% for the observation and document review, respectively. Items with lower agreement were primarily staff behavior, counting across the day/week, and policy classifications. CONCLUSIONS Although some revisions are required, the interobserver agreement for the environment and policy assessment and observation (EPAO instrument) appears to be quite good for assessing the nutrition and physical activity environment of child care centers.

Dietary Intakes in North Carolina Child-Care Centers: Are Children Meeting Current Recommendations?

The purpose of this study was to determine whether food consumed by children while in center-based child care meets the new MyPyramid food group recommendations for children 2 to 5 years of age. Dietary observation of 117 children from 20 child-care centers throughout North Carolina was conducted. The type and amount of food served to and consumed by children was observed and assessed using Nutrition Data System for Research (NDS-R) software (version 2005, Nutrition Coordinating Center, University of Minnesota, Minneapolis). Portion sizes were then compared to the new MyPyramid food group recommendations to see whether 1/2 to 2/3 (for time spent in full-day child care) of the recommended amounts were consumed. On average, of the five main food groups, children consumed only the 1/2 to 2/3 recommendation for milk. Children also consumed less than 13% of MyPyramid recommendations for whole grains and 7% of MyPyramid recommendations for dark vegetables. Also noteworthy, 50% of milk consumed was whole milk and 75% of the meat consumed was of the high-fat or fried variety. Overall, our data suggest that children are not consuming recommended amounts of whole grains, fruits (excluding 100% fruit juice), or vegetables while attending full-time child care, and are consuming excess amounts of saturated fat and added sugar.

Dysregulation of cardiovascular and neuroendocrine responses to stress in premenstrual dysphoric disorder

Twelve women with prospectively confirmed premenstrual dysphoric disorder (PMDD or PDD) were compared with 12 healthy control subjects for cardiovascular and neuroendocrine responses to speech and mental arithmetic (Paced Auditory Serial Addition Task) stressors during both the follicular and luteal phases of the menstrual cycle. Structured clinical interview was used to assess psychiatric and abuse histories, and standardized questionnaires were administered to assess current life stress. Results revealed that PMDD women had significantly lower stroke volume, cardiac output and cortisol levels but significantly elevated norepinephrine and total peripheral resistance at rest and also during mental stressors compared with control subjects. These effects were evident in both cycle phases. Significantly more women with PMDD had histories of sexual abuse, and they also reported greater current life stress than control subjects. Consistent with a history of trauma, the PMDD women exhibited significantly greater ratios of norepinephrine to cortisol at rest and during stress. These results are interpreted as reflecting dysregulation of the stress response and may be related to histories of severe and/or chronic exposure to stress for a subgroup of PMDD women.

Menus in Child Care: A Comparison of State Regulations with National Standards

The purpose of this project was to compare individual state regulations regarding menus for child-care centers and family child-care homes with national menu standards. For all 50 states and the District of Columbia, state regulations were compared with menu standards found in Caring for Our Children--National Health and Safety Performance Standards: Guidelines for Out-of-Home Child Care Programs. Specifically, these guidelines suggest that (a) menus must be posted or made available to parents, (b) menus must be dated, (c) menus must reflect food served, (d) menus must be planned in advance, and (e) menus must be kept on file. One additional standard, that menus in child care are reviewed by a nutrition professional, was added to this review. Data were collected between June and August of 2007. Substantial variation existed among state regulations regarding menus. For child-care centers, seven states (14%) included regulations on all five standards, and 13 states (25%) had regulations on four of the five menu standards. Ten states (20%) did not have any regulations on the five menu standards. For family child-care homes, only three states (6%) had regulations on all five menu standards; four states (8%) had regulations on four of the five menu standards. Twenty-seven states (53%) did not have any regulations on the five standards for menus. Within the same state, regulations for child-care centers and family child-care homes often did not match. Overall, great discrepancies were found between model child-care menu policies and current state regulations in most states. States have the opportunity to improve regulations regarding menus to ensure that child-care providers develop accurate, specific, and healthful menus.

Improving Nutrition and Physical Activity in Child Care: What Parents Recommend

A large percentage of children in the United States spend part of their day in out-of-home child care. As rates of obesity continue to rise, especially among young children, child care has become a focus for nutrition and physical activity intervention. Parental involvement is an important component of these efforts. During summer 2006, parents of children in child care were surveyed to better understand their perceived quality of meals, snacks, and physical activity at the child-care center, and their recommendations for improvement. Parents of children who attended 94 licensed child-care centers in North Carolina were invited to complete a brief survey of perceived quality of meals, snacks, and physical activity at their centers using close-ended questions. Open-ended questions were used to identify suggestions for improvement. Five hundred eight parents from 91 child-care centers completed the questionnaire. The majority of parents reported quality of meals and snacks at the center as either excellent (30% meals, 27% snacks) or good (42% meals, 46% snacks). The main recommendations for improving meals and snacks were to increase fruits and vegetables and provide a variety of healthful foods. The majority of parents categorized the quality of physical activity at the center as excellent (36%) or good (46%), and suggested more structured, outdoor activities for children. Findings from this study provide insight into key areas of concern for parents regarding the nutrition and activity environment of child-care centers. This information may be used to create or modify interventions or policies and to help motivate parents to become advocates for change in child care.

Can distance education prepare future public health nutritionists? A case study.

OBJECTIVE To assess student retention, readiness, support and outcomes among students completing the Professional Practice Program in Nutrition (PPPN). DESIGN Qualitative evaluation using semistructured, in-depth interviews conducted with PPPN graduates. Course grades, grade point averages, and comprehensive exam results compared 10 PPPN students from 2 cohorts and 72 residential students from 3 cohorts. SETTING The Professional Practice Program in Nutrition was a 3-year, pilot public health nutrition masters (MPH) degree curriculum using distance education (DE) strategies. ANALYSIS Ethnograph was used to assist with qualitative data analysis. Fisher exact test was used to compare quantitative outcomes. RESULTS Qualitative findings revealed that PPPN students were highly motivated, sought out the DE MPH and initially had great support from family and employers; however, support from employers waned over time. Although several challenges to continued enrollment confronted PPPN students, those who completed the MPH all advanced in the workplace. Course grades and grade point averages were similar between the 2 groups. Students in the PPPN were more likely than residential students to retake the comprehensive exam. CONCLUSIONS AND IMPLICATIONS The findings indicate that DE strategies were suitable to deliver an MPH curriculum in nutrition. The majority of PPPN graduates experienced job advancement and demonstrated leadership development.
