简要总结
The ENLIGHTENme project aims at collecting evidence about the impact of outdoor and indoor lighting on human health and wellbeing through the development and testing of innovative solutions and policies that will also counteract health inequalities in European cities. In particular, through an open-online Urban Lighting and Health Atlas, ENLIGHTENme will collect and systematize existing data and good practices on urban lighting and will perform an accurate analysis on the correlations among health, wellbeing, lighting and socio-economic factors in three pilot cities: Bologna (Italy), Amsterdam (The Netherlands), and Tartu (Estonia).
详细描述
The ENLIGHTENme project aims at collecting evidence about the impact of outdoor and indoor lighting on human health and wellbeing through the development and testing of innovative solutions and policies that will also counteract health inequalities in European cities. In particular, through an open-online Urban Lighting and Health Atlas, ENLIGHTENme will collect and systematize existing data and good practices on urban lighting and will perform an accurate analysis on the correlations among health, wellbeing, lighting and socio-economic factors in three pilot cities: Bologna (Italy), Amsterdam (The Netherlands), and Tartu (Estonia).
In this context, the ENLIGHTENme project will also include an interventional, multicenter, prospective, randomized, controlled, unblinded trial involving one target district, selected based on its artificial light characteristics, in the urban areas of each of one of the three pilot cities. Within each target district, a random sample of individuals aged 65 years or older (intervention group) will be exposed to modifications in domestic indoor lighting and compared with a control group, living in the same target district, unexposed to domestic electric light modifications. At the same time, in a specific area of the target district, outdoor lighting will be modified by the local municipal authority. The hypothesis to be tested in this study is that light interventions may improve individual physical and mental health by affecting circadian entrainment, sleep pattern, and mood. Thus, the study is aimed at providing evidence whether the planned change in electric light exposure at both urban public outdoor and domestic indoor lighting levels may impact on physical and mental health by improving photo-entrainment of circadian rhythms to the light-dark cycle

研究组 & 干预措施
indoor light intervention
Persons allocated to the indoor light intervention arm will be given a lamp to be placed at home
干预措施: indoor light intervention (Behavioral)
control group
Persons allocated to the control group will receive no indoor light supplementation and will undergo assessment procedures only
干预措施: no indoor light (Behavioral)
结局指标
主要结局
impact of electric light on sleep quality
时间窗: Basal+14 days
to evaluate the impact of electric light on sleep quality as measured with the Pittsburgh Sleep Quality Index (PSQI), a 19-item self-reported questionnaire that measures sleep quality over the previous month. A higher score indicates poorer sleep quality, therefore the hypothesis to be tested is that a participant's sleep quality will improve (i.e. PSQI score will decrease) at the end of the light intervention period compared to baseline.
次要结局
- Change in photoentrainment(from baseline and the end of the light intervention period - 52 weeks)
- Change in mental and physical health(from baseline and the end of the light intervention period - 52 weeks)
- actigraphic and melatonin assays(- 52 weeks)
- circadian rest-activity measures(from baseline and the end of the light intervention period - 52 weeks)
