| In the research and application of medical and health care,it is the key to evaluate the health benefits of the healing garden.The existing problems are that many studies can not prove or effectively evaluate the health gain,and one-sided only through some psychological and physiological indicators to evaluate the health gain.Most of the world’s cases that can prove the health gain of healing garden are psychological evaluation,heart rate,blood pressure,brain wave and other physiological indicators.How to prove that the use of healing garden can obtain health gain,whether users can obtain effective health results,health evaluation methods and evidence-based experimental design are the difficulties of application evaluation of healing garden in the field.The research objectives are to explore the expression of healing garden design,the participatory design of horticultural activities,the evaluation of health gain after the use of healing garden,to explore the correlation between horticultural activities and different perspectives of health gain evaluation,the feasibility of different evaluation methods,and the correlation between participatory design and health gain,these are of great significance for the theory and practice of health gain of healing garden.Based on the previous research,volunteers from 45 to 70 years old were recruited in 2018-2019.In the design of participatory activities,in 2018,activities were 5 months,75 times,and exercised every other day for 1.5 hours.In 2019,activities were 6 months,53 times,and 2 activities per week,2 hours each time.Taking the "PlanT" healing garden as the place,we designed different year,season and activity mode,collected and analyzed the data of the constitution in Chinese medicine questionnaire(CCMQ),SCL-90,Self-Rating Anxiety Scale(SAS),Self-Rating Depression Scale(SDS)before and every month of activities of individual volunteers.Analyzed the differences of physiological indicators,human body composition,cardiovascular function and mental stress before and after activities in 2018;combined with interviews and questionnaires,comprehensively analyze the dynamic changes of health gain of volunteers participating in activities from quantitative and qualitative perspectives.Analyzed the characteristics of health gain of volunteers in three years included 2017,and explored the correlation between the design of horticultural activities in healing garden and the health gain of volunteers.The main results were as follows:(1)The overall evaluation of the health gain of volunteers in the participatory design of"PlanT" healing garden researchIn 2018-2019,based on the selection and application of edible plants,medicine and food homologous plants,and focused on the diversity of flower species,landscape and seasonal changes,it was effective for health gain.Participatory design activity mode of horticultural activities,planting edible plants,container cultivation,seeding and seedling raising,watering and weeding,natural education,picking and sharing activities.The proportion of male and female design volunteers was close,the age difference between 45 and 70 years old was large,and the acquaintances participated in the activities and cooperated in groups.In general,mental health had been improved effectively,physical health of traditional Chinese medicine(TCM)had been improved effectively,and the proportion had changed from biased constitution to gentleness constitution,and in terms of mental stress,the overall gain was effective,which proved that the two-year repeated experiment health gain of participatory design of horticultural activities in healing garden was effective.The results of health gain were different with different horticultural activity mode.(2)Evaluation of traditional Chinese Medicine(TCM)Data collection was done by wechat to fill in CCMQ and used tongue surface phase instrument to evaluate type.After the volunteer activities,in 2018 and 2019,there were 26.67%and 18.52%respectively,which had changed from biased constitution to gentleness constitution,and the attendance rate of volunteers was positively related to the health gain;the health gain of walking to the garden was more obvious;the physical change was related to the climate.In 2018,the gentleness constitution score increased significantly(P<0.01),8 kinds of biased constitution score decreased,5 kinds score had extremely significant difference(P<0.01),2 kinds score had significant difference(P<0.05).In 2019,the gentleness constitution score increased significantly(P<0.05),8 kinds of biased constitution score decreased,5 kinds had extremely significant difference(P<0.01),2 kinds had significant difference(P<0.05),2 years control group had no significant difference.The health of 22 and 10 volunteers who participated in the activities for 2 and 3 years in a row has been improved to varying degrees,although there were different factors such as activity design and climate.(3)Mental health evaluationAfter the activities in 2018 and 2019,the adverse psychological symptoms decreased gradually,anxiety and depression tendency improved,and mental health improved significantly.In 2018,the scores of SCL-90 decreased,and "somatization" had extremely significant difference(P<0.01),the total average score,the number of positive items,the number of negative items,"obsessive-compulsive symptoms" and "interpersonal sensitivity" had significant difference(P<0.05),and the scores of SAS and SDS decreased significantly(P<0.01).In 2019,the scores of SCL-90 decreased,the number of positive items,negative items and "interpersonal sensitivity" had significant difference(P<0.05),SAS and SDS decreased,SAS had significant difference(P<0.05),SDS had extremely significant difference(P<0.01).The control group had no significant difference for 2 years.There was a positive correlation between attendance and mental health gain.For 2 and 3 years,there were differences in the mode,climate and other factors of the activity participatory design,and the mental health of the volunteers had been improved to varying degrees.(4)Evaluation of human body composition,cardiovascular function and mental stressThe data collected before and after the activity in 2018 showed that there was no significant change in the body composition of volunteers.In the cardiovascular function,the heart function,blood vessels,blood and microcirculation of volunteers were improved,but there were no significant difference.In the analysis of mental stress,the ability to resist pressure of volunteers improved significantly(P<0.01),the balance of autonomic nervous system increased significantly(P<0.05),and the attendance rate of volunteers was positively correlated with the level of mental stress.(5)Subjective cognition of volunteers on horticultural activities and physical and mental healthIn the 2018 interview analysis,the results of the subjective cognitive participation activities of volunteers were mainly divided into four aspects:psychological spirit,body,knowledge and skills,social interaction,among which the psychological spirit and body gains were more prominent,accounting for 42.67%and 32.88%respectively.The main reasons for volunteers to participate in the activities were physical and mental health,closeness to nature and social activities,of which the proportion of physical and mental health and closeness to nature were relatively large,accounting for 44.00%and 40.00%respectively.91.67%of the volunteers thought that collective activities and individual activities should be included in the design of horticultural activities,but they had different cognition on the frequency of activities. |
