Using Participatory Action Research to Develop a School-based Environmental Intervention to Support Healthy Eating and Physical Activity

Barriers exist to healthy eating and physical activity for children in the school environment. Modifiable school environmental factors have led to the development of the Nutrition Friendly Schools and Communities (NFSC) model to prevent the development of overweight in school children and adolescents. The design of the NFSC environmental intervention is to actively engage the school community to prevent overweight in school-aged children. This article presents data measuring the environmental changes achieved by the Los Angeles Unified School District (LAUSD) elementary schools participating in a 3-year participatory research pilot study funded by the Centers for Disease Control and Prevention (CDC). An objective of the pilot study is to determine whether any or all of the 15 steps developed for the NFSC model could be implemented. Further, researchers want to know if any of the study schools could implement the NFSC model as a whole during the allotted time of the pilot study.

Background One of the current public health problems in Bulgaria is the high prevalence of overweight and obesity in childhood. The family environment affects many aspects of children’s health and well-being. The unfavourable socio-economic characteristics of the family environment might be a risk for overweight and obesity in childhood. Methods A national representative survey was conducted in Bulgaria in 2016 as part of the WHO European Childhood Obesity Surveillance Initiative (COSI). 3379 schoolchildren were recruited. The average age of the sample was 7.7 years, equally distributed by gender - girls 50.11% (n = 1693) and boys 49.89% (n = 1686). The data from the filled in Family form was analysed with SPSS using descriptive statistical methods. Results The study identified the following risk factors of the family environment for the development of overweight in childhood: the proportion of parents with elementary or primary education was significant - about a quarter, nearly one third of the surveyed households were experiencing financial difficulties, 14.1% of the women and 11.6% of the men were unemployed in the last 1 year. There was a high incidence of co-morbidity among family members: hypertension - 27.7%, diabetes mellitus - 14.4% and hypercholesterolemia - 13.6%. Among the surveyed parents 28.4% of the women and 68% of the men were overweight. Only 13.5% of the parents estimated the weight status of their child as overweight (with objectively measured overweight among 29.2% of the recruited children). A significant proportion of the children were not breastfed (17.3%) or the duration of exclusive breastfeeding was not optimal for 67.8% of the exclusively breastfed children. Conclusions Identifying family risk factors associated with overweight in childhood is important for the public health and provides opportunities to develop policies for improvement of the nutritional and health status of children. Key messages To tackle the childhood obesity epidemic the family risk factors should be addressed. The awareness of the children and parents should be raised through targeted information materials and campaigns.

Coordinated school health programs (CSHPs) bring together educational and community resources in the school environment. This method is particularly important in rural areas like Kansas, where resources and trained health professionals are in short supply. Rural Stafford County, Kansas, struggles with health professional shortages and a low-income, high-need population. In 2001, Stafford County's Unified School District 349 began a multiyear CSHP development process, which required adaptations for implementation in a rural area. First, a CSHP team was formed of community and administrative stakeholders as well as school system representatives. Next, the CSHP team assessed school district demographics so the program framework could be targeted to health needs. During a yearlong planning phase, the CSHP team determined 4 priority areas for program development, as limited staff and funds precluded developing programs in all 8 traditional CSHP areas. Program activities were tailored to the population demographics and available resources. Program outcomes were supported by School Health Index (SHI) data. Of the 8 CSHP focus areas, the SHI found high scores in 3 of the Stafford CSHP's priority areas: Health Services; Psychological, Counseling, and Social Services; and Physical Education. The fourth Stafford CSHP priority area, Nutrition Services, scored similarly to the less prioritized areas. The process by which the Stafford school district modified and implemented CSHP methods can serve as a model for CSHPs in other rural, high-need areas.

Physical Activity Measures in the Healthy Communities Study.

Purpose: to study prevalence and main risk factors for overweight and obesity in children and adolescents aged 6–17 and develop appropriate prevention measures. 
 Materials and Methods. Bibliographic, statistical and sociological methods.
 Results. It is noted an insufficient level of registration of obesity among children. During the study it was found that true prevalence of obesity and overweight in children and adolescents in Kharkiv is significantly different from the official statistics in Kharkiv region ((151.0±5.2)‰). 22 factors of risk had a reliable impact on the development of overweight in children and adolescents. The main risk factors for the formation of the overweight were biological and social and hygienic. Based on the results of the research it was proved that the key measures to reduce the prevalence of obesity and its consequences should be aimed at modifying risk factors, namely: changing stereotypes and habitats that contribute to pathology and at improving the quality of health care, basically at the primary level. Thus priority measures for improvement the quality of health care for children and adolescents with obesity should include: mandatory monitoring of body mass index among children from the age of 3 and assessment of the harmony of physical development; introduction of an information system for accounting, monitoring of obesity and overweight and the main risk factors (electronic medical record of the patient); introduction of patient registers at the territorial and regional level; preferential supervision by the family doctor, involvement of all experts; raising public awareness at the group, individual level; timely identification of risk factors, formation of risk groups, organization of dynamic monitoring, creation of differentiated prevention programs and study of public awareness of the main risks of overweight; advanced training of doctors, conducting training seminars on nutrition.
 Conclusions. Thus, to solve the problem of obesity in children such structures as local governments, educational institutions, healthcare institutions and public organizations should be obligatory involved. Special attention is paid to measures to optimize medical care at the primary level for such children.

To evaluate whether breast feeding is associated with prevalent overweight in pre-adolescent children. Cross-sectional studies of 9 to 10-y-old children attending fourth grade in 1995/1996 in Dresden (n=1046) and Munich (n=1062), Germany, according to the International Study of Asthma and Allergies in Childhood (ISAAC) Phase II protocol. A comprehensive questionnaire including detailed breast feeding history was filled out by the child's parent. Height and weight were measured in a random subsample of children undergoing spirometry. Overweight was defined as body mass index > or =90th age- and sex-specific percentile of the German reference. While the prevalence of overweight differed substantially between Dresden (girls 9.1%, boys 12.5%) and Munich (17% both), we observed a markedly lower overweight prevalence among breast fed than non-breast fed children in both cities. Controlling for age, sex and city, breast-fed children were substantially less likely to be overweight at 9-10 y (OR 0.55, 95% CI 0.41-0.74). Results were slightly attenuated after adjustment for nationality, socio-economic status, number of siblings, parental smoking (OR 0.66, 95% CI 0.52-0.87). A longer overall duration and duration of exclusive breast feeding was associated significantly with decreasing prevalence of overweight. The results highlight the importance and possible preventive potential of early nutrition in the development of overweight in children. Both feeding behaviors acquired by the nursing infant and metabolic effects may contribute to the observed inverse association of breast feeding and overweight in children.

Special Issue on Childhood Overweight and Obesity and New Special Magnet Feature

Addressing childhood overweight has become a top priority in the United States. Modification of school policies and practices has been used in an attempt to address the overweight epidemic among children and adolescents. Culturally diverse urban schools in low-income communities attempting to improve nutrition and increase physical activity may face unique challenges in the school environment. A better understanding is needed about school environments and how they may affect the implementation, efficacy, and sustainability of initiatives designed to improve nutrition and physical activity. We carried out a qualitative study in five urban middle schools in low-income communities that had recently implemented Planet Health, a nutrition and physical activity intervention, to assess which aspects of the schools' physical, social, and policy environments were facilitating or impeding the implementation of health promotion initiatives. Thirty-five faculty and staff members participated. We conducted one focus group per school, with an average of seven participants per group. We analyzed focus group transcripts using the thematic analysis technique to identify key concepts, categories, and themes. Teachers and staff members in our study identified many school-related environmental barriers to successful implementation of nutrition and physical activity initiatives in their schools. School personnel recommended that classroom-based nutrition interventions such as Planet Health be coordinated with school food services so that the healthy messages taught in the classroom are reinforced by the availability of healthy, culturally appropriate cafeteria food. They identified household food insufficiency and overly restrictive eligibility criteria of the federally subsidized meal program as critical barriers to healthy nutritional behaviors. They also identified weight-related teasing and bullying and unhealthy weight-control behaviors as challenges to promotion of healthy nutrition and physical activity. To maximize intervention efforts, researchers and practitioners must consider the effects of school environments on nutrition and physical activity initiatives.

This case study profiles one of 24 high schools that participated in a school-based, NIH-funded study to increase physical activity among high school girls. The case study school was one of 12 randomly assigned to the intervention group. The study intervention was based on the premise that a successful intervention is developed and tailored by teachers and staff to fit the context of their school. Intervention guidelines (Essential Elements) and the Coordinated School Health Program (CSHP) model were used to direct intervention activities for physical education, health education, school environment, school health services,faculty/staff health promotion, andfamily/community involvement. All girls at the case study school received the intervention. A team of school employees provided leadership to develop and implement the intervention in collaboration with a university project staff. Data collected over a two-year period were used to describe changes that occurred in each CSHP area. Key changes were made in the school environment, curricula, policies, and practices. Qualitative measures showed girls more involved in physical activity. Quantitative measures taken in eighth grade, and repeated with the same set of girls in ninth grade, showed increases in both moderate-to-vigorous physical activity (p = < .01) and vigorous physical activity (p = .04). Other schools can use this case to modify components of the CSHP model to increase physical activity among high school girls.

The COMPASS Study: A New Cohort Study Examining How Changes in School Policies, Programs, and The Built Environment are Associated With Obesity and Correlates of Obesity Among Students Over Time

635 Understanding parent perceptions of healthy physical activity for their child with a chronic medical condition

As researchers continue to analyze the role of parenting both in the development of childhood overweight and in obesity prevention, studies of child nutrition and growth are detailing the ways in which parents affect their children's development of food- and activity-related behaviors. Ana Lindsay, Katarina Sussner, Juhee Kim, and Steven Gortmaker argue that interventions aimed at preventing childhood overweight and obesity should involve parents as important forces for change in their children's behaviors. The authors begin by reviewing evidence on how parents can help their children develop and maintain healthful eating and physical activity habits, thereby ultimately helping prevent childhood overweight and obesity. They show how important it is for parents to understand how their roles in preventing obesity change as their children move through critical developmental periods, from before birth and through adolescence. They point out that researchers, policymakers, and practitioners should also make use of such information to develop more effective interventions and educational programs that address childhood obesity right where it starts-at home. The authors review research evaluating school-based obesity-prevention interventions that include components targeted at parents. Although much research has been done on how parents shape their children's eating and physical activity habits, surprisingly few high-quality data exist on the effectiveness of such programs. The authors call for more programs and cost-effectiveness studies aimed at improving parents' ability to shape healthful eating and physical activity behaviors in their children. The authors conclude that preventing and controlling childhood obesity will require multifaceted and community-wide programs and policies, with parents having a critical role to play. Successful intervention efforts, they argue, must involve and work directly with parents from the earliest stages of child development to support healthful practices both in and outside of the home.

The COVID-19 lockdowns and social distancing measures, including school closures, had a major impact on children's physical activity in England, with data showing an initial reduction in activity in the short-term post-lockdown phase of the pandemic followed by a recovery on average in the medium-term post-lockdown period. The school environment is an important context for child physical activity. The purpose of this study is to understand the changes that took place to school physical activity environments once schools reopened after lockdowns. This information will improve understanding of why changes to children's physical activity have occurred over the course of the pandemic and the implications for future promotion of physical activity in schools. Interviews with parents (n = 43), school staff (n = 18) and focus groups with 10- to 11-year-old children (participant n = 92) were conducted at two time points: between September-December 2021 and February-July 2022. Interview and focus group guides covered the impact of the pandemic on child physical activity and changes to this over time. The framework method was used for analysis. Three themes and three subthemes were generated: (1) the return to school; (2) over-pressured staff and environment and (3) the uneven impact of the pandemic. Theme 3 consists of three subthemes: (a) retained pandemic policies, (b) impact on physical activity culture and (c) different children need different things. Conducting this research in schools during ongoing COVID-19 disruptions was a challenge and may have limited school and participant participation, particularly school staff. The parent interview sample is predominantly female, active and of higher socioeconomic status, so the experiences of male, less active and lower socioeconomic parents are limited. This study suggests that the impact of COVID-19 on child physical activity is uneven, affecting some children more than others. Future work is therefore needed to explore the details of this potential diverging experience. The COVID-19 pandemic, school closures and post-lockdown school policies have impacted upon primary school physical activity environments. The post-lockdown school environment is highly pressured, impacting the extent to which schools can support and encourage child physical activity. Future research is needed to further explore the impact of post-lockdown changes on physical activity environments in schools, particularly over the longer term, as schools continue to adapt post lockdowns. Strategies required to support school physical activity environments must be context specific and sensitive to these changes, pressures and needs. This article presents independent research funded by the National Institute for Health and Care Research (NIHR) Public Health Research programme as award number NIHR131847.

BackgroundGlobally, the high prevalence of overweight and low levels of physical activity among children has serious implications for morbidity and premature mortality in adulthood. Various parental factors are associated with childhood overweight and physical activity. The objective of this paper was to investigate relationships between parental education or overweight, and (i) child overweight, (ii) child physical activity, and (iii) explore household coexistence of overweight, in a large international sample.MethodsData were collected from 4752 children (9–11 years) as part of the International Study of Childhood Obesity, Lifestyle and the Environment in 12 countries around the world. Physical activity of participating children was assessed by accelerometry, and body weight directly measured. Questionnaires were used to collect parents’ education level, weight, and height.ResultsMaternal and paternal overweight were positively associated with child overweight. Higher household coexistence of parent-child overweight was observed among overweight children compared to the total sample. There was a positive relationship between maternal education and child overweight in Colombia 1.90 (1.23–2.94) [odds ratio (confidence interval)] and Kenya 4.80 (2.21–10.43), and a negative relationship between paternal education and child overweight in Brazil 0.55 (0.33–0.92) and the USA 0.54 (0.33–0.88). Maternal education was negatively associated with children meeting physical activity guidelines in Colombia 0.53 (0.33–0.85), Kenya 0.35 (0.19–0.63), and Portugal 0.54 (0.31–0.96).ConclusionsResults are aligned with previous studies showing positive associations between parental and child overweight in all countries, and positive relationships between parental education and child overweight or negative associations between parental education and child physical activity in lower economic status countries. Relationships between maternal and paternal education and child weight status and physical activity appear to be related to the developmental stage of different countries. Given these varied relationships, it is crucial to further explore familial factors when investigating child overweight and physical activity.

The prevalence of childhood obesity is increasing, and schools are ideal places to support healthy eating and physical activity. In 2000, the Centers for Disease Control and Prevention (CDC) developed the School Health Index, a self-assessment and planning tool that helps schools evaluate and improve physical activity and nutrition programs and policies. Although many state education agencies, health departments, and individual schools have used the School Health Index, few systematic evaluations of the tool have been performed. We examined the physical activity and nutrition environments in Rhode Island's public elementary schools with high and low minority student enrollments and evaluated a school-based environmental and policy intervention that included implementation of the School Health Index. As part of a CDC Division of Nutrition and Physical Activity cooperative agreement awarded to the Rhode Island Department of Health, we conducted a needs assessment of 102 elementary schools and implemented an intervention in four inner-city elementary schools. In phase 1, we analyzed the Rhode Island Needs Assessment Tool (RINAT), a telephone survey of principals in approximately 50% of all Rhode Island public elementary schools in the state during the 2001-2002 school year (n = 102). Comparisons of the nutrition and physical activity environments of schools with low and high minority enrollment were calculated by cross-tabulation with the chi-square test. In phase 2, we used process and outcome evaluation data to assess the use of the School Health Index in creating healthier environments in schools. Our intervention--Eat Healthy and Get Active!--involved implementing three of the eight School Health Index modules in four Rhode Island elementary schools. Survey data revealed that schools with high minority enrollment (student enrollment of > or =10% black, > or =25% Hispanic, or both) offered few programs supporting healthy eating and physical activity (P < .05). Schools with high and low minority enrollment both offered nonnutritious foods and beverages. Process evaluation data revealed that 1) principals play a pivotal role on School Health Index teams, 2) schoolwide validation of a team's small successes is crucial for sustaining a commitment to healthy lifestyle policies and programs, and 3) external facilitators are essential for implementation success. Outcome data showed that all schools developed at least one policy or environmental strategy to create a healthy school environment. Only two schools implemented immediate changes. Needs assessment, external facilitation, and evaluation are the foundation for sustainable school-based policies. Although the School Health Index is universally perceived as a user-friendly assessment tool, implementation is likely to be less successful in schools with low staff morale, budgetary constraints, and inconsistent administrator support.
