A Systematic Review Protocol Investigating Community Gardening Impact Measures

State Legislation Related to School Nutrition: Predictors of Bill Passage From 2010-2019

OBJECTIVE

This study aimed to discover the prevalence of school nutrition state legislation and to identify the correlates of enactment.

DESIGN, SETTING, AND PARTICIPANTS

An online legislative database, Legiscan, was used to collect bills related to school nutrition from the US from 2010 to 2019. Bills were coded and compiled into a study database with state-level dietary variables (obesity prevalence, fruit, and vegetable intake, sugar-sweetened beverage consumption), community variables (percent White, poverty), and bill-characteristic variables (party affiliation in legislature, strength of language, party of governor, school gardens, vegetable intake, and other salient variables). Multivariable models were built to examine predictors of bill enactment.

RESULTS

Of the 462 bills introduced, 38.7% (n = 156) were enacted. In a multivariable model, the strength of bill language, political party affiliation, implementation of school gardens, and vegetable intake were the variables associated with bill passage. Bills with strong language were less likely to be enacted (P <0.001). Bills introduced by Democrats were more likely to be enacted (P = 0.01).

CONCLUSION AND IMPLICATION

This study showed a better understanding of legislative support for child nutrition via policy surveillance of bills and their correlates of enactment. This information can be used to prioritize advocacy efforts and identify ways research can better inform policy.

School Gardening and Health and Well-Being of School-Aged Children: A Realist Synthesis

School environments can create healthy settings to foster children's health and well-being. School gardening is gaining popularity as an intervention for healthier eating and increased physical activity. We used a systematic realist approach to investigate how school gardens improve health and well-being outcomes for school-aged children, why, and in what circumstances. The context and mechanisms of the specific school gardening interventions (n = 24) leading to positive health and well-being outcomes for school-aged children were assessed. The impetus of many interventions was to increase fruit and vegetable intake and address the prevention of childhood obesity. Most interventions were conducted at primary schools with participating children in Grades 2 through 6. Types of positive outcomes included increased fruit and vegetable consumption, dietary fiber and vitamins A and C, improved body mass index, and improved well-being of children. Key mechanisms included embedding nutrition-based and garden-based education in the curriculum; experiential learning opportunities; family engagement and participation; authority figure engagement; cultural context; use of multi-prong approaches; and reinforcement of activities during implementation. This review shows that a combination of mechanisms works mutually through school gardening programs leading to improved health and well-being outcomes for school-aged children.

Design and Social Factors Affecting the Formation of Social Capital in Chinese Community Garden

In recent years, community gardens are becoming more and more popular in China. However, the role of these community gardens varies significantly: some community gardens serve as an effective means of promoting social capital, while others cause social contradictions and public doubts due to the lack of professional design and management. Therefore, this paper aims to learn and better understand what factors affect the formation of social capital in Chinese community gardens. It screened eleven design factors and seven social factors and made social capital scale through literature review and expert workshop. On this basis, this study selected 35 community gardens in China as sample spaces, and collected 1257 questionnaires about the perception for social capital of gardeners through survey. In the statistical analysis phase, factor analysis and regression analysis were applied to analyze the role and the relative importance of different factors and social capital. Results show that the integration with green infrastructure, accessibility, size, visual openness, planting form, proportion of unproductive landscape, agricultural infrastructure, and smart infrastructure have significant impacts on social capital level. Meanwhile, the types of stakeholders, management rules, supervision system, self-management team, and operational activities have similar impacts on social capital level. This study recommends that planners and designers should adjust the above related factors in community garden design, and local government is urged to integrate community gardens into urban plans and public policies.

Community Gardening: Stress, Well-Being, and Resilience Potentials

The financial and health burdens of stress associated with increased urbanization have led to a demand for mental health enhancement strategies. While some extant literature details mental health benefits of community gardening, a coherent narrative on the construct of resilience and its relationship with the mental health benefits of community gardening is lacking. The present study examined the relationship between community gardening and a number of mental health benefits, in the forms of subjective well-being, stress, resilience potentials, and resilience factors (self-esteem, optimism, and openness). A total of 111 residents in Singapore completed a survey. Results from Multivariate Analysis of Covariance (MANCOVA) and Pearson’s correlation analyses show that, after controlling for age and levels of connection to nature, community gardeners reported significantly higher levels of subjective well-being than individual/home gardeners and non-gardeners, indicating that engagement in community gardening may be superior to individual/home gardening or non-gardening outdoor activities. Community gardeners reported higher levels of resilience and optimism than the non-gardening control group. These novel results indicate some potential for mental health benefits in urban environments, specifically in terms of subjective well-being and resilience. These findings have implications for future research in clinical psychology, mental health promotion, and policy.

Are Community Gardening and Horticultural Interventions Beneficial for Psychosocial Well-Being? A Meta-Analysis

Recent literature has revealed the positive effect of gardening on human health; however, empirical evidence on the effects of gardening-based programs on psychosocial well-being is scant. This meta-analysis aims to examine the scientific literature on the effect of community gardening or horticultural interventions on a variety of outcomes related to psychosocial well-being, such as social cohesion, networking, social support, and trust. From 383 bibliographic records retrieved (from 1975 to 2019), seven studies with a total of 22 effect sizes were selected on the basis of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Meta-analytic findings on 11 comparisons indicate a positive and moderate effect of horticultural or gardening interventions on psychosocial well-being. Moderation analysis shows a greater effect size in individualistic than collectivistic cultures. A greater effect size was also observed in studies involving community gardening compared to horticultural intervention. Nevertheless, an effect of publication bias and study heterogeneity has been detected. Despite the presence of a large number of qualitative studies on the effect of horticulture/gardening on psychosocial well-being, quantitative studies are lacking. There is a strong need to advance into further high-quality studies on this research topic given that gardening has promising applied implications for human health, the community, and sustainable city management.

A Systematic Review Protocol to Identify the Key Benefits and Associated Program Characteristics of Community Gardening for Vulnerable Populations

Gardening has long been a popular pastime. There is a growing evidence base for the health and well-being benefits of gardening. Community gardening brings a social aspect to gardening, thereby increasing the potential benefits to include addressing social inclusion and poor community health through sharing of values, support of others, and building networks. This systematic review protocol aims to determine the characteristics of community gardening that could lead to beneficial outcomes such as connection with the community and development of new skills. Thirteen academic databases will be searched for studies looking at the benefits of community gardening, with a focus on vulnerable populations. Data will be extracted from all studies meeting the inclusion criteria and summarized to provide an overview of the current literature. This systematic review aims to provide a comprehensive investigation into community gardening, its benefits, and how they are achieved for the target population. By gathering and synthesizing this information, the review should allow policy makers and practitioners to work more effectively to address health and social inequities, by highlighting areas of need and enabling optimization of future interventions.
