研究概览
简要总结
The JArDinS study is a quasi-experimental research that aimed at assessing the impact of community garden participation (a natural experiment) in the adoption of more sustainable lifestyles.
详细描述
The JArDinS study is part of the SURFOOD-Foodscapes project evaluating the relationships between urban foodscape and food styles in Montpellier Metropole (France).
JArDinS consists of a pretest-posttest quasi-experimental research and includes an experimental group of new gardeners starting gardening in a community garden in Montpellier and a control group comprising participants from a survey on food behaviors undertaken as part of SURFOOD-Foodscapes project. Participants will be surveyed at enrollment and 12 months later.

结局指标
主要结局
Change in environmental impact of household's food trip (in g CO2eq)
时间窗: at baseline and exactly 12 month later
For each food trip, the distance traveled specifically for food purchase will be multiplied by energy source consumption of the transportation used, and by the corresponding GHGE factor of source consumption. GHGE related to food trip will be calculated as the sum of all food trips during the period of data collection.
Change in sensibility to food waste
时间窗: at baseline and exactly 12 month later
Assessed by the Sensibility to food waste scale, a 8-item scale rated on a 7-point Likert-type, that measure in which extent participants attach importance to waste and are emotionally affected by it. Total score range from 7-56, a higher total scores denote greater sensibility to food waste.
Change in household food supply expenditure
时间窗: at baseline and exactly 12 month later
Monthly household food expenditure and the contribution of each food group and subgroup to total food expenditure were estimated using food expenses data collected in the food supply diary.
Change in social isolation
时间窗: at baseline and exactly 12 month later
Assessed by the UCLA Loneliness Scale. UCLA-3 is a 20-item scale (11 positive and 9 negative) rated on a 4-point Likert-type. Total score range from 20-70, with higher scores greater feelings of loneliness.
Change in healthiness of household food supply
时间窗: at baseline and exactly 12 month later
The nutritional quality of household food supply was estimated using two indicators of nutritional quality : the mean adequacy ratio (MAR) and the mean excess ratio (MER)
Change in physical activity energy
时间窗: at baseline and exactly 12 month later
Physical activity energy expenditure were estimated directly from raw triaxial accelerometry data using a model which combines an automatic activity-recognition algorithm with an activity-specific count-based model
Change in environmental impact of household's food supply
时间窗: at baseline and exactly 12 month later
Greenhouse gas emissions (in g CO2eq), atmospheric acidification (g SO2eq) and marine eutrophication (in g Neq) related to household's food supply were computed using estimates from the French 'SUStable' table.
Change in connection with nature
时间窗: at baseline and exactly 12 month later
Affective, cognitive, and experiential aspects of individuals' connection to nature was assessed by the Nature Relatedness Scale (NRS). NRS is a 21-item scale rated on a 5-point Likert-type. Total score range from 5-105, a higher total scores denote greater nature connectedness.
Change in mental well-being
时间窗: at baseline and exactly 12 month later
Assessed by the Warwick-Edinburgh Mental Wellbeing Scale. WEMWBS is a 14-item scale rated on a 5-point Likert-type, in which all items are worded positively and address aspects of positive mental health. Total score range from 14-70, with higher scores indicating a higher level of mental well-being.
次要结局

- Age (in year) of each member of the household(at baseline)
- Education level of each adult of the household(at baseline)
- Gender of each member of the household(at baseline)
- Household income(at baseline)
