Acculturation and Health Status in the Children's Healthy Living Program in the Pacific Region.

Acculturation/enculturation has been found to impact childhood health and obesity status. The objective of this study is to use cross-sectional data to examine the association between proxies of adult/caregiver acculturation/enculturation and child health status (Body Mass Index [BMI], waist circumference [WC], and acanthosis nigricans [AN]) in the U.S.-Affiliated Pacific Islands (USAPI), Alaska, and Hawai'i. Study participants were from the Children's Healthy Living (CHL) Program, an environmental intervention trial and obesity prevalence survey. Anthropometric data from 2-8 year olds and parent/caregiver questionnaires were used in this analysis. The results of this study (n = 4121) saw that those parents/caregivers who identified as traditional had children who were protected against overweight/obesity (OWOB) status and WC > 75th percentile (compared to the integrated culture identity) when adjusted for significant variables from the descriptive analysis. AN did not have a significant association with cultural classification. Future interventions in the USAPI, Alaska, and Hawai'i may want to focus efforts on parents/caregivers who associated with an integrated cultural group as an opportunity to improve health and reduce child OWOB prevalence.

An Exploratory Mixed Method Cross-Sectional Study to Identify Opportunities to Increase Enrollment and Retention of Native Hawaiian Students in an Undergraduate Dietetic Program.

BACKGROUND: Native Hawaiians (NH) are underrepresented in dietetics, contributing to less than 1% of the profession nationally. Increasing the number of NH Registered Dietitian Nutritionists (RDN) is one mechanism to facilitate improved health outcomes in disparate populations. OBJECTIVES: 1) Identify and summarize NH student interests in the field of nutrition and dietetics; 2) Identify and contextualize factors that support and prohibit achievement of academic goals and aspirations; 3) Identify NH students' responsibility to the community; 4) Explore the context around NH alumni enrollment in nutrition and dietetics and their perceived impact of RDNs in the community; 5) Identify and describe supporting agencies that foster academic and professional success. DESIGN: This exploratory mixed-methods cross-sectional study surveyed all levels of NH nutrition and dietetics students in the University of Hawai'i (UH) System. In addition, in-depth interviews were conducted with NH students, NH alumni, and supporting agencies to identify supports and barriers, explore the context of NH enrollment in nutrition and dietetics, and the contribution of dietetics to the NH community. PARTICIPANTS/SETTING: Eighty-one NH students enrolled in a nutrition course across the UH system were surveyed. Nine of the 81 NH students surveyed, eight NH alumni, and persons from 15 identified supporting agencies were interviewed. ANALYSIS: Survey responses were descriptively analyzed. Open-ended survey questions and interviews were analyzed through content analysis. To ensure findings were guided by NH perspective, data were triangulated by researchers and a NH dietetics advisory council. RESULTS: Food and chronic disease prevention and management were topics that drew NH students to the field. Bridge/scholarship programs supported NH academic achievement. Education-related cost was a perceived barrier. Alumni and students shared varying degrees of responsibility to serve the NH community. Increasing the connection between NH values and the nutrition and dietetics curriculum are an identified need. CONCLUSION: Findings illuminate opportunities to drive future programmatic efforts. The framework used in this study should be adaptable to other programs to support overall dietetics diversity initiatives.

Exploring Foods of the Pacific: Cultural Food Identity in the US Affiliated Pacific Region.

Indigenous peoples of the Pacific have seen major shifts in dietary patterns due to foreign colonization, which introduced an array of new foods. Today, foods considered traditional and acculturated are consumed in various extents. However, the definitions and identity of traditional versus acculturated foods has become unclear as many introduced foods have been incorporated into Pacific cultures. The purpose of this study was to capture culturally relevant definitions of traditional, acculturated, and locally grown foods among 10 jurisdictions of the US-Affiliated Pacific (USAP) region with a focus on fruits and vegetables. Questionnaires were used to capture definitions of these terms, and to identify a list of foods (n=121) as traditional, acculturated, and/or locally grown in addition to classify them into food groups (ie, fruit, vegetable, starch, and/or grain). For the most part, definitions of traditional, acculturated, and locally grown were agreed upon by participating USAP jurisdictions, with some supplementary caveats presented by different jurisdictions. More foods were identified as acculturated (n=75) than traditional (n=37). Fruits (n=55) were the most frequent designation and about a third were vegetables (n=44). The majority of the jurisdictions reported growing at least half of the food items. This is the first study to identify and classify foods of the Pacific from the perspective of those indigenous to the USAP region. Understanding these similarities and differences in how food is classified and identified, through the lens of those from the Pacific, is crucial for nutrition education, and understanding what foods are locally grown is important for future sustainability.

A Qualitative Analysis of a Caregivers' Experience of Complementary Feeding in a Population of Native Hawaiian, Other Pacific Islander and Filipino Infants: The Timing of the Introduction of Complementary Foods, and the Role of Transgenerational Experience.

The aim of this study was to investigate caregivers' experiences of complementary feeding (CF) among the Native Hawaiian and Other Pacific Islander (NHPI), and Filipino populations. Research focused on the timing of CF commencement, and the influence of transgenerational experience on feeding practices. The experiences and practices of those who fed human milk exclusively (HME), were compared to those who included infant formula (F&HM). Caregivers of a subset of 32 infants who were participating in a larger longitudinal study relating to CF and diet diversity, took part in voluntary in-depth interviews relating to CF practices. Interviews were recorded and transcribed. Two researchers analyzed interview transcripts. Interrater reliability and saturation were established. Institutional Review Board exemption was confirmed prior to study commencement. Interviews with 29 caregivers of infants were included in this study. Only infants of the F&HM group had an early introduction to complementary foods (<4 months of age). Caregivers reported receiving conflicting advice from healthcare professionals (HCPs) in relation to timing of the introduction of complementary foods. Nonetheless, the majority of caregivers reported following the advice of HCPs. Extended family (including grandparents) played less of a role in infant feeding, compared to previous generations. While transgenerational practices were valued and included, ultimately, the perceived health and safety of the practice for infants influenced decisions.

Consumption of Traditional Fruits and Vegetables among Children in the US-Affiliated Pacific Region.

Background: Traditional Pacific diets have many health benefits, including maintenance of a healthy weight and prevention of various diseases. Few studies have evaluated the frequency at which traditional diets are consumed in the Pacific, especially among children. Objectives: This study examined the frequency of traditional and acculturated fruit and vegetable (F&V) intake among children in the US-affiliated Pacific (USAP) region. Methods: Diet records of 3319 children ages 2 to 8 y old were analyzed for frequency of traditional or acculturated F&V intake within USAP jurisdictions of American Samoa, Commonwealth of the Northern Mariana Islands (CNMI), Federated States of Micronesia (FSM; FSM island states include Chuuk, Kosrae, Pohnpei, and Yap), Guam, Hawaii, Republic of the Marshall Islands (RMI), and Republic of Palau. Results: Of the 95,304 food items recorded among participating children in the USAP jurisdictions, 15.2% were F&Vs. Of the 10 jurisdictions, children in the islands of Chuuk, Kosrae, Yap, and Pohnpei recorded the highest frequencies of traditional F&V intake relative to their total F&V intake (67.8%, 64.8%, 56.7%, and 52.5%, respectively). American Samoa and RMI recorded moderate frequency of traditional F&V intake (38.9% and 46.4%, respectively), whereas children in Hawaii, Guam, and CNMI recorded the lowest frequencies of traditional F&V intake relative to their total F&V intake (10.4%, 12.4%, and 15.3%, respectively). Children in Hawaii, Guam, Palau, and CNMI recorded high frequencies of acculturated F&V intake (37.8%, 31.2%, 34.5%, and 27.9%, respectively). Conclusions: Overall, children in the USAP jurisdictions participating in this study recorded a low frequency of F&V intake. The differences in traditional F&V intake found between the USAP islands may be due to variation in economic income level and external influences on social and cultural norms among the island populations and variations of cost, accessibility, and convenience of each category of food to each island's population.

Hawai'i Registered Dietitian Nutritionist 2019-2020 Workforce Assessment.

There is scant literature available on the Registered Dietitian Nutritionist (RDN) workforce in the United States, but a review of healthcare systems suggests that implementation of RDNs in primary care settings may improve access to care, patient satisfaction, and quality of care. The Area Health Education Center (AHEC), in partnership with the Hawai'i Academy of Nutrition and Dietetics (HAND), investigated 395 providers to evaluate the status of Hawai'i's RDN workforce. The research team utilized all available provider information and direct calling methodology to collect data from August 2019 to February 2020. Microsoft Excel software allowed for data analysis and ArcGIS mapping software was used to visualize provider totals and Full-Time Equivalencies (FTEs) across the state. This study identifies trends in workforce demographics and provider supply. Researchers found 100 RDNs providing direct patient care for a total of 82.4 FTEs. Women account for 94% of survey respondents, and the average age of providers was 48. RDNs who self-identify as being Asian American (41%) or White (47%) were the largest ethnic groups providing direct patient care. Seventy percent of the RDN workforce was located on O'ahu, while RDN FTEs are concentrated in mainly 5 zip codes, 1 on each of O'ahu, Kaua'i, and Maui and 2 on Hawai'i Island. Provider demand trends, increased training and retention efforts, and integration of nutritional services in healthcare teams should be further investigated.

An Active Image-Based Mobile Food Record Is Feasible for Capturing Eating Occasions among Infants Ages 3-12 Months Old in Hawai'i.

The ability to comprehensively assess the diet of infants is essential for monitoring adequate growth; however, it is challenging to assess dietary intake with a high level of accuracy. Infants rely on surrogate reporting by caregivers. This study aimed to determine if surrogate reporters (e.g., caregivers) could use an image-based mobile food record adapted (baby mFR) to record infants' eating occasions, and via caregiver feedback, could assess the usability and feasibility of the baby mFR in recording infants' diets. This was a cross-sectional study in which surrogate reporters (e.g., caregivers) recorded all food and beverage intake (including human milk) of the infant over a 4-day period. Trained research staff evaluated all images submitted during data collection for different indicators of quality. All surrogate reporters were asked to complete a usability questionnaire at the end of the 4-day data collection period. Basic descriptive analyses were performed on the infants 3-12 months of age (n = 70). A total of 91% (n = 64) of surrogate reporters used the baby mFR to record their infants' eating occasions. The mean number of images submitted daily per participant via the mFR was 4.2 (SD 0.2). A majority of submitted images contained the fiducial marker and the food and/or beverage was completely visible. The mFR was found to be easy to use; however, suggestions were provided to increase utility of the application such as the inclusion of a bottle button and reminders. An image-based dietary assessment method using a mobile app was found to be feasible for surrogate reporters to record an infant's food and beverage intake throughout the day.

Associations between Cultural Identity, Household Membership and Diet Quality among Native Hawaiian, Pacific Islander, and Filipino Infants in Hawai'i.

Public health efforts to reduce diet-related health disparities experienced by indigenous peoples could be enhanced by efforts to improve complementary infant feeding practices. The latter is possible through interventions informed by cultural determinants. This cross-sectional secondary analysis explored possible determinants of the complementary feeding practices of Native Hawaiian, Pacific Islander, and/or Filipino infants (NHPIF) in Hawai'i, ages 3-12 months. The objective was to determine the association between caregiver cultural identity and infant household membership with indicators of infant diet healthfulness. The cultural identities, infant household memberships, early infant feeding practices and additional demographic information (infant age and sex, household income) were assessed via an online questionnaire. Surrogate reporting of the infants' diets over four days was evaluated using an image-based mobile food record (mFR). Data collected by the mFR were evaluated to derive the World Health Organization's minimum dietary diversity (MDD) indicator and food group consumption. Data were summarized by descriptive statistics and analyzed using multivariate linear and logistic regressions. Seventy infant participants, ages 3-12 months, and their primary caregivers completed the study. Of these, there were 56 infant participants between the age of 6-12 months. Approximately 10% of infants, ages 6-12 months, met MDD for all four days. Meeting MDD and the number of food groups consumed were significantly associated with age. Caregiver cultural identity, infant household membership and infant sex had non-significant associations with indicators of infant diet quality. Findings inform the influences shaping dietary patterns of Native Hawaiian, Pacific Islander and Filipino infants in Hawai'i.

Native Hawaiian Complementary Feeding Practices as Told by Grandparents: A Transgenerational Experience.

BACKGROUND: Infancy is a significant disease prevention and health promotion stage in life. There is a need to examine factors influencing complementary feeding among Native Hawaiians through an indigenous framed lens. OBJECTIVES: To identify Hawaiian complementary feeding practices through in-depth interviews with kupuna (grandparents) from across the state of Hawai'i. METHODS: The chain-referral-sampling method was used to identify Native Hawaiian kupuna knowledgeable in Hawaiian complementary feeding practices from across 4 counties in Hawai'i. Interview question topics included sharing about their formative years, infant health, infant feeding, transgenerational knowledge, and opportunities and barriers related to traditional food consumption. Interviews were recorded and then transcribed. Three coders used NVivio12 to code transcripts using a priori and emergent themes. Institutional Review Board approval was received prior to data collection. RESULTS: Fourteen kupuna interviews were included in the analysis. A majority of the kupuna were female. Most kupuna shared that complementary feeding practices in their childhood and when their children and grandchildren were being raised reflected aspects of the traditional Hawaiian diet. Poi, or steamed mashed taro root, was the most common traditional Hawaiian dietary staple of infancy. However, kupuna shared that traditional dietary practices evolved to reflect contemporary dietary practices such as the mixing of poi with infant cereal or milk. Female family members were prominent influences on kupuna complementary feeding practices. Lifestyle and lack of knowledge were the most commonly shared reflections by kupuna on the supports and barriers, respectively, to promoting and engaging in traditional Hawaiian complementary feeding practices. CONCLUSIONS: Complementary feeding practices have evolved over generations but aspects of traditional Hawaiian feeding practices have remained. These findings are important when working with Hawaiian families because kupuna play a prominent role in feeding infants.

Determination of Child Waist Circumference Cut Points for Metabolic Risk Based on Acanthosis Nigricans, the Children's Healthy Living Program.

INTRODUCTION: Waist circumference is a common anthropometric measure for predicting abdominal obesity and insulin resistance. We developed optimal waist circumference cut points for children aged 2 to 8 years in the US-Affiliated Pacific (USAP) region based on the relationship of waist circumference and acanthosis nigricans in this population. METHODS: We conducted a cross-sectional analysis from the Children's Healthy Living Program's 2012-2013 data on 4,023 children. We used receiver-operating characteristic analysis to determine the sensitivity and specificity for acanthosis nigricans across waist circumference, by sex and age. We determined optimal waist circumference cutoff points corresponding to Youden index (J), (equal to [sensitivity + specificity] - 1), with acanthosis nigricans. We compared these cut points with the 90th percentile. RESULTS: The 90th-percentile cut points for boys aged 2 to 5 years (58.15 cm) and 6 to 8 years (71.63 cm) were slightly higher than for girls in both age groups (aged 2-5 y, 57.97 cm; 6-8 y: 70.37 cm). The optimal cut points (corresponding to the highest sensitivity and specificity) were as follows: for boys aged 2 to 5 years, 90th percentile (58.25 cm; sensitivity, 48.0%; specificity, 91.5%); for boys aged 6 to 8 years, 78th percentile (63.59 cm; sensitivity, 86.8%; specificity, 82.8%); for girls aged 2 to 5 years, 62nd percentile (53.27 cm; sensitivity, 71.4%; specificity, 63.1%), and for girls aged 6 to 8 years, 80th percentile (63.63 cm; sensitivity, 55.4%; specificity, 82.9%). CONCLUSION: Among USAP children, waist circumference was a reasonable predictor for acanthosis nigricans. Further analysis is warranted to examine causes of acanthosis nigricans at lower-than-expected waist circumference percentiles. The cut points can be used for early detection of metabolic risk.

Food Security and Diet Quality in Native Hawaiian, Pacific Islander, and Filipino Infants 3 to 12 Months of Age.

Food insecurity and other nutritional risks in infancy pose a lifelong risk to wellbeing; however, their effect on diet quality in Native Hawaiian, Pacific Islander, and Filipino (NHPIF) infants in Hawai'i is unknown. In this cross-sectional analysis, the association between various indicators of food security and NHPIF infant diet quality were investigated in 70 NHPIF infants aged 3-12 months residing on O'ahu, Hawai'i. The dietary assessments of the infants were collected using a mobile food recordTM. Foods consumed across four days were categorized into seven food groups. Indicators for food security were examined through an adapted infant food security index and other indicators. Data were analyzed using chi-square tests, independent sample t-tests, multinomial logistic regression, and linear regression models. In models adjusting for age and sex, infants defined as food insecure by the adapted index were found to consume foods from more food groups and consume flesh foods on a greater proportion of days. Of the indicators examined, the adapted index was shown to be the best indicator for food group consumption. Further work is needed on a more representative sample of NHPIF infants to determine the impact that food security has on nutritional status and other indicators of health.

Type, Timing, and Diversity of Complementary Foods Among Native Hawaiian, Pacific Islander, and Filipino Infants.

Prevention is the recommended strategy for addressing childhood obesity and may be particularly important for minority groups such as Native Hawaiians, Pacific Islanders, and Filipinos (NHPIF) who display poorer health outcomes than other race/ethnic groups. Complementary feeding is a critical milestone in the first 1,000 days of life and plays a critical role in growth and eating habit formation. This cross-sectional study recruited NHPIF infants between 3 - 12 months of age residing on O'ahu, Hawai'i to examine timing and types of complementary foods introduced first as well as the dietary diversity of those infants 6 - 12 months of age. Basic demographic information and early feeding practices were assessed via online questionnaire. Diet was evaluated using the image-based mobile food record completed over 4-days. Images were evaluated to derive the World Health Organization's minimum dietary diversity (MDD) score. Data were analyzed using descriptive statistics and linear regressions. Seventy participants completed the study with a majority being between the ages of 6 - 12 months (n=56). About half of the participants were provided a complementary food prior to 6 months of age with the most common first complementary food being poi (steamed, mashed taro). Grains were the most commonly reported food group while the high protein food groups was the least commonly reported. Approximately 25% of infants 6 - 12 months of age met MDD all four days. Meeting MDD was significantly associated with age. Findings illuminate opportunities for improvement (eg, delayed introduction) and for promotion (eg, cultural foods) in NHPIF complementary feeding.

Open Educational Resource Textbook Impact on Students in an Introductory Nutrition Course.

OBJECTIVE: To determine if student outcomes, usage, perceptions, and engagement differ between introductory nutrition courses that used an open educational resource (OER) textbook compared with a traditional textbook. DESIGN: Cross-sectional. SETTING: College introductory nutrition course. PARTICIPANTS: Students enrolled in introductory nutrition courses that used a traditional textbook or an OER textbook. INTERVENTION: Implementation of an OER textbook in all introductory nutrition courses during 1 semester. MAIN OUTCOME MEASURE(S): Usage, perceptions, and engagement with the textbook were evaluated by an online survey. Student outcome data (eg, grades) were collected from the learning management system at the end of the semester. ANALYSIS: Differences in student outcomes, usage, perceptions, and engagement were determined by t tests. Open-ended responses on textbook likes and dislikes were evaluated by thematic analysis. RESULTS: The number of students who completed the introductory nutrition course with a traditional textbook (n = 346) was higher than those who completed the course with an OER textbook (n = 311). There was no difference in student outcomes between textbooks. P values for student usage ranged from <.001 to .001, <.001 for engagement, and <.001 to .001 for perception with the OER textbook, with significantly better P values for outcomes than those with the traditional textbook. The $0 cost and place-based nature were noted as positive attributes of the OER textbook, whereas students appreciated the format and visual appeal of the traditional textbook. CONCLUSIONS AND IMPLICATIONS: Academic performance in introductory nutrition was not affected by an OER textbook. An OER textbook for introductory nutrition may be an appropriate solution for institutions seeking to reduce student costs.

Plate Waste in School Lunch: Barriers, Motivators, and Perspectives of SNAP-Eligible Early Adolescents in the US.

OBJECTIVE: To determine barriers, motivators, and perspectives regarding plate waste reduction of early adolescents. DESIGN: Trained interviewers conducted audio-recorded individual interviews with adolescents. SETTING: Elementary schools implementing the National School Lunch Program in Hawai'i, Montana, and Virginia. PARTICIPANTS: Early adolescents (n = 47, aged 9-13 years) from families receiving or eligible to receive Supplemental Nutrition Assistance Program benefits were recruited to participate. PHENOMENON OF INTEREST: Factors influencing plate waste among adolescents and potential plate waste reduction strategies. ANALYSIS: Coders analyzed content and thematic data to identify code categories and themes. RESULTS: Main barriers to reducing school lunch plate waste were unsupportive school policy, undesirable food quality, satiation, and social influences. Key motivators to reducing school lunch plate waste were supportive school policy, including allowing students to share food with peers and save food to eat later; and social influences. Participants found it acceptable to throw away disliked food and unacceptable to throw away wanted food; they perceived that their peers did not care whether food was thrown away; and they thought their parents disliked wasting food. CONCLUSION AND IMPLICATIONS: Results suggest that several factors might allow for minimization of school lunch plate waste in the National School Lunch Program, including improvements in food quality, food policy, and social influences. Under these important themes, strategies to employ may include improving food preparation and taste, allocating more time for students to finish lunch, allowing students to self-select food lunch items, and permitting them to share and save their leftover food.

Collecting wrappers, labels, and packages to enhance accuracy of food records among children 2-8 years in the Pacific region: Children's Healthy Living Program (CHL).

The aim was to describe differences in dietary outcomes based on the provision of food wrappers, labels or packages (WLP) to complement data from dietary records (DR) among children from the US Affiliated Pacific. The WLP were intended to aid food coding. Since WLP can be associated with ultra-processed foods, one might expect differences in sodium, sugar, and other added ingredients to emerge. Dietary intakes of children (2-8 y) in Alaska, Hawai'i, Commonwealth of the Northern Mariana Islands, and Guam were collected using parent/caregiver completed 2-day DR. Parents were encouraged to collect WLP associated with the child's intake. Trained staff entered data from the DRs including the WLP when available using PacTrac3, a web application. Of the 1,868 DRs collected and entered at the time of this report, 498 (27%) included WLP. After adjusting for confounders (sex, age, location, education, food assistance), the DRs with WLP had significantly higher amounts of energy (kcal), total fat, saturated fat, added sugar, and sodium. These results suggest the inclusion of WLP enhanced the dietary intake data. The intake of energy, fat, added sugar and sodium derived from processed foods and foods consumed outside the home was better captured in children who had WLP.

Influence of Teachers' Personal Health Behaviors on Operationalizing Obesity Prevention Policy in Head Start Preschools: A Project of the Children's Healthy Living Program (CHL).

OBJECTIVE: To quantify the Head Start (HS) teacher mediating and moderating influence on the effect of a wellness policy intervention. DESIGN: Intervention trial within a larger randomized community trial. SETTING: HS preschools in Hawaii. PARTICIPANTS: Twenty-three HS classrooms located within 2 previously randomized communities. INTERVENTION: Seven-month multi-component intervention with policy changes to food served and service style, initiatives for employee wellness, classroom activities for preschoolers promoting physical activity (PA) and healthy eating, and training and technical assistance. MAIN OUTCOME MEASURES: The Environment and Policy Assessment and Observation (EPAO) classroom scores and teacher questionnaires assessing on knowledge, beliefs, priorities, and misconceptions around child nutrition and changes in personal health behaviors and status were the main outcome measures. ANALYSIS: Paired t tests and linear regression analysis tested the intervention effects on the classroom and mediating and moderating effects of the teacher variables on the classroom environment. RESULTS: General linear model test showed greater intervention effect on the EPAO score where teachers reported higher than average improvements in their own health status and behaviors (estimate [SE] = -2.47 (0.78), P < .05). CONCLUSIONS AND IMPLICATIONS: Strategies to improve teacher health status and behaviors included in a multi-component policy intervention aimed at child obesity prevention may produce a greater effect on classroom environments.

Head Start Wellness Policy Intervention in Hawaii: A Project of the Children's Healthy Living Program.

BACKGROUND: The increased prevalence of childhood overweight and obesity across the United States and the Pacific has become a serious public health concern, with especially high prevalence among Native Hawaiian and Pacific Islander (NHPI) children. This study aimed to measure the effect of a Head Start (HS) policy intervention for childhood obesity prevention. METHODS: Twenty-three HS classrooms located in Hawaii participated in the trial of a 7-month policy intervention with HS teachers. Classroom- and child-level outcome assessments were conducted, including: the Environment and Policy Assessment and Observations (EPAO) of the classroom environment; plate waste observations to assess child intake of fruit and vegetables; and child growth. RESULTS: The intervention showed a positive and significant effect on classroom EPAO physical activity (PA) and EPAO total scores. Although mean BMI z-score (zBMI) increased at postintervention for both intervention (mean = 0.60; standard deviation [SD], 1.16; n = 114) and delayed-intervention groups (mean = 0.35; SD, 1.17; n = 132), change in zBMI was not significantly different between the groups (p = 0.50; p = 0.48). CONCLUSIONS: These findings contribute evidence on the potential for HS wellness policy to improve the PA environment of HS classrooms. More research is needed to link these policy changes to other child outcomes.
