"Kids Get in Shape with Nature": A Systematic Review Exploring the Impact of Green Spaces on Childhood Obesity

Neighborhood Characteristics Related to Changes in Anthropometrics During a Lifestyle Intervention for Persons with Obesity

BACKGROUND

Since obesity has emerged as a major public health concern, there is an urgent need to better understand factors related to weight gain and treatment success.

METHODS

This study included 118 persons with obesity who participated in a multidisciplinary combined lifestyle intervention with cognitive-behavioral therapy at the outpatient clinic of the Obesity Center CGG at Erasmus University Medical Center, Rotterdam, The Netherlands. Neighborhood characteristics were assessed using a 13-item questionnaire. Multiple regression analyses were performed to examine the association between perceived safety, social cohesion, and the availability of facilities on relative changes in body mass index and waist circumference changes, adjusted for corresponding neighborhood socioeconomic status scores.

RESULTS

Higher total scores, indicating more unfavorable neighborhood perceptions, were associated with less relative improvements in BMI and waist circumference after 1.5 years (β = 3.2, 95%CI 0.3-6.0; β = 3.4, 95%CI 0.3-6.6, respectively). Also, more neighborhood unsafety was associated with less relative improvements in BMI and waist circumference on the long term (β = 3.1, 95%CI 1.1-5.1; β = 2.8, 95%CI 0.6-5.1, respectively).

CONCLUSION

The results indicate that living in a neighborhood perceived as less favorable may lower the chances of successful weight loss in response to combined lifestyle interventions in persons with obesity.

The Health-Related and Learning Performance Effects of Air Pollution and Other Urban-Related Environmental Factors on School-Age Children and Adolescents-A Scoping Review of Systematic Reviews

PURPOSE OF REVIEW

This scoping review aims to assess the impact of air pollution, traffic noise, heat, and green and blue space exposures on the physical and cognitive development of school-age children and adolescents. While existing evidence indicates adverse effects of transport-related exposures on their health, a comprehensive scoping review is necessary to consolidate findings on various urban environmental exposures' effects on children's development.

RECENT FINDINGS

There is consistent evidence on how air pollution negatively affects children's cognitive and respiratory health and learning performance, increasing their susceptibility to diseases in their adult life. Scientific evidence on heat and traffic noise, while less researched, indicates that they negatively affect children's health. On the contrary, green space exposure seems to benefit or mitigate these adverse effects, suggesting a potential strategy to promote children's cognitive and physical development in urban settings. This review underscores the substantial impact of urban exposures on the physical and mental development of children and adolescents. It highlights adverse health effects that can extend into adulthood, affecting academic opportunities and well-being beyond health. While acknowledging the necessity for more research on the mechanisms of air pollution effects and associations with heat and noise exposure, the review advocates prioritizing policy changes and urban planning interventions. This includes minimizing air pollution and traffic noise while enhancing urban vegetation, particularly in school environments, to ensure the healthy development of children and promote lifelong health.

Greenspaces and Health: Scoping Review of studies in Europe

Objectives

Access to greenspaces and contact with nature can promote physical activity and have positive effects on physical and mental health. This scoping literature review aims to examine current evidence linking greenspaces and (a) behaviour change, (b) health outcomes and (c) co-benefits.

Methods

This review was conducted in accordance with the PRISMA scoping review guidelines. Searches were conducted through PubMed and EMBASE databases for studies published between 2000 and March 2023 with a focus on Europe.

Results

122 scientific articles and grey literature reports were identified. Access to greenspaces is positively associated with physical and mental health, and reduced risk of all-cause mortality and some non-communicable diseases. Greenspace quality is associated with increased physical activity and reduced risk of obesity. Nature-based therapies or green prescription are effective in improving mental health outcomes and overall health. Importantly, numerous co-benefits of greenspaces are identified.

Conclusion

Increasing access to greenspaces for populations with particular attention to greenspace quality is important for co-benefits. Responsible governance and use of greenspaces are crucial to minimize public health risks and human disturbance of nature.

Food and Physical Activity Environment in the US-Affiliated Pacific Region: The Children's Healthy Living Program

OBJECTIVE

To describe the quality of food and physical activity (PA) environments by World Bank Income level in jurisdictions from the Children's Healthy Living Program.

DESIGN

Baseline cross-sectional community data were analyzed from 11 jurisdictions categorized by World Bank Income levels to describe exposure to different food and PA outlets. The Children's Healthy Living Program was a multilevel, multijurisdictional prevalence study and community intervention trial that reduced child obesity in the US-Affiliated Pacific region.

SETTING

US-Affiliated Pacific region.

PARTICIPANTS

Food (n = 426) and PA (n = 552) Outlets.

MAIN OUTCOME MEASURES

Physical activity and food scores that reflect the quality of the outlets that support being physically active and healthy eating options, respectively.

ANALYSIS

Descriptive statistics are presented as means ± SD or percentages.

RESULTS

High-income-income level jurisdictions had higher food and PA scores than middle-income level jurisdictions.

CONCLUSIONS AND IMPLICATIONS

The US-Affiliated Pacific region has limited quality food and PA outlets in underserved communities at risk for obesity. The findings in this paper can be used to develop tools and design interventions to improve the food and PA environment to increase a healthier, active lifestyle.

Relationship between "Blue Space" Proximity and Children's Weight Status, Health Behaviors, and Health-Related Quality of Life among a Sample of Regional Victorian Primary School Children

Background: Access to green space (e.g., parks and gardens) has been associated with child health and wellbeing, whereas blue space (e.g., coasts, lakes, and rivers) is understudied. Our aim was to determine whether proximity to the coast was associated with primary school children's weight status, modifiable health-related behaviors, and health-related quality of life (HRQoL). Methods: Exploratory cross-sectional analysis of baseline data from the Whole of Systems Trial of Prevention Strategies for Childhood Obesity (WHOSTOPS) study, to estimate gender-specific differences in weight and behaviors across four bands of distance from the coast (<5 km, 5 to <25 km, 25 to <50 km, ≥50 km). Linear and logistic models, with robust standard errors, adjusted for school year level, area-level socioeconomic position and rurality, and allowing for distance by gender interaction were fitted on data from 1216 children (aged 8.5-13 years). Main outcomes were weight status (categorical), physical activity (PA) (categorical), and global HRQoL score (continuous). Results: Compared with girls living in towns ≥50 km from the coast, those living within 5 km had lower odds for overweight/obesity [odds ratio (OR) = 0.50; 95% confidence interval (CI): 0.37-0.67] and higher mean moderate-to-vigorous PA minutes (accelerometry) (β = 8.7; 95% CI: 2.0-15.5) and global HRQoL (β = 3.2; 95% CI: 1.4-5.0). Compared with boys living ≥50 km from the coast, those living within 5 km had higher odds of meeting self-reported PA guidelines (≥60 minutes/day) for ≥5 days (OR = 2.33; 95% CI: 1.75-3.10), and higher mean global HRQoL scores (β = 5.6; 95% CI: 1.9-9.3). Conclusions: Living close to the coast was associated with some favorable health outcomes and behaviors, which differed between girls and boys.

Developing an Approach for Assessing Urban Blue-Green Spaces Towards Sustainable Urban Growth Through Retrospective Cyber Metrics Analysis of Operational Estimations Approaches

Urban blue-green spaces provide us abundant social, environmental, and economic benefits, but the disparities often exist in their distribution and accessibility. Traditionally urban blue-green spaces are a consolidation of “blue-green infrastructure” within urban areas. Several urban features like parks, forests, gardens, visible water, such as parks, rivers, canals, reservoirs, ponds, lakes, fountains, etc. are categorized or considered under the blue-green spaces and these are very much crucial for various urban ecosystem services. These play a significant role for all stakeholders of the urban community. Thus, everyone must ensure the equitable number of blue-green spaces for all. Recently, several rules and regulations towards the safeguarding of urban blue-green spaces have been outlined. The work presents a methodological framework to develop an approach towards sustainable urban growth with the help of urban blue-green spaces assessments. The current work has attempted to examine the linkage between issues of the urban blue-green spaces for restoring the required infrastructures. It can be utilised for all sustainable urban development for urban planning and design projects to play a pivotal role. The work emphasizes more to develop a methodological framework to analyze the urban blue-green spaces for augmentation with a theoretical framework. It is expected that the advancement of a problem cum objectives-driven approach will help to design an impact-driven approach for planned and concrete action.
