Despite an increasing number of studies highlighting the health benefits of community gardening, the literature is limited by cross-sectional designs. The "JArDinS" quasi-experimental study aimed to assess the impact of community garden participation on the adoption of more sustainable lifestyles among French adults.
Individuals entering a community garden in Montpellier (France) in 2018 (n = 66) were compared with pairwise matched individuals with no experience in community gardening (n = 66). Nutritional quality, environmental impact and cost of monthly household food supplies, level of physical activity measured by accelerometers, as well as mental and social well-being, sensitivity to food waste, and connection with nature were evaluated at baseline (t0) and 12 months later (t1) to explore sustainability of lifestyles in social/health, environmental and economic dimensions. Linear mixed models were used to determine the independent effect of community gardening on investigated lifestyles components. In-depth interviews were conducted at t1 with 15 gardeners to better understand changes that may have occurred in gardeners' lives during the first year of gardening.
At t0, gardeners had lower education level, lower BMI and their household reported lower percentage of meals consumed outside of the home compared to non-gardeners (p < 0.05). Participating in the community garden had no significant impact, in spite of sufficient statistical power, on fruit and vegetables supplies (main outcome), nor on physical activity parameters, nor on others of the social/health, environmental and economic lifestyles components investigated. Qualitative interviews suggested the existence of pre-established health and environmental consciousness in some gardeners and revealed several barriers to the participation such as lack of time, lack of gardening knowledge, physical difficulty of gardening, health problems and conflicts with other gardeners.
The health benefits of community gardening previously reported by cross-sectional studies might be confounded by selection bias. The JArDinS study highlights the need to identify solutions to overcome barriers related to community garden participation when designing relevant public health interventions for the promotion of sustainable lifestyles.
The study was registered at clinicaltrials.gov as NCT03694782 . Date of registration: 3rd October 2018, retrospectively registered.
尽管越来越多的研究强调社区园艺对健康有益，但相关文献受限于横断面设计。“JArDinS”准实验研究旨在评估法国成年人参与社区园艺对采用更可持续生活方式的影响。
将2018年进入法国蒙彼利埃一个社区花园的个人（n = 66）与两两匹配的无社区园艺经验的个人（n = 66）进行比较。在基线（t0）和12个月后（t1）评估家庭每月食物供应的营养质量、环境影响和成本、通过加速度计测量的身体活动水平，以及心理和社会幸福感、对食物浪费的敏感度和与自然的联系，以探讨社会/健康、环境和经济层面生活方式的可持续性。使用线性混合模型确定社区园艺对所调查生活方式组成部分的独立影响。在t1时对15名园艺参与者进行了深入访谈，以更好地了解园艺参与者在园艺第一年生活中可能发生的变化。
在t0时，与非园艺参与者相比，园艺参与者的教育水平较低、体重指数较低，且其家庭报告在家外就餐的比例较低（p < 0.05）。尽管有足够的统计效力，但参与社区园艺对水果和蔬菜供应（主要结果）、身体活动参数以及所调查的社会/健康、环境和经济生活方式的其他组成部分均无显著影响。定性访谈表明，一些园艺参与者存在预先确立的健康和环境意识，并揭示了参与的几个障碍，如时间不足、缺乏园艺知识、园艺的身体困难、健康问题以及与其他园艺参与者的冲突。
横断面研究先前报道的社区园艺对健康的益处可能受到选择偏倚的混淆。“JArDinS”研究强调，在设计促进可持续生活方式的相关公共卫生干预措施时，需要确定克服与社区园艺参与相关障碍的解决方案。
该研究在clinicaltrials.gov上注册为NCT03694782。注册日期：2018年10月3日，追溯注册。
