Green Space, Mental Health and Sleep

世界卫生组织指出，10%至20%的儿童和青少年有儿科心理健康 预计到2030年，全球经济负担将达到6万亿美元。在国际扶轮， 约19%的17岁以下儿童面临心理健康挑战 对他们的发展、教育、同伴关系和身体健康造成不利影响。睡眠是 对心理健康和幸福的贡献者日益得到认可。在儿童中，不充分 睡眠被认为与心理和身体健康状况恶化有关。暴露在绿地中， 广义上定义为各种形式的植被，已被证明具有多种健康作用 福利。在这项研究中，我们打算探索暴露于绿地之间的联系 以及小学生的心理健康状况。目标1.睡眠和绿地。 确定绿地利用率(全球定位系统衍生的日常活动和 环境特征)与儿童睡眠(持续时间、时间、规律性)有关。假设 1.1儿童在GPS衍生的绿地上花费更多时间(即利用率)将 更早、更长时间和更规律的睡眠比孩子们在绿地上花费的时间更少。 假设1.2。绿地的利用将通过增加光照影响睡眠， 使用加速度计测量的较高的体力活动水平和较低的压力水平 用IL-1β测定。目标2.心理健康、绿地和睡眠。确定是否 绿地利用通过睡眠行为与心理健康和幸福感相关。 假设2.1：儿童在绿地呆的时间越长，心理健康状况就越差 通过经过验证的PROMIS®焦虑、认知功能、 心理压力和幸福感相比，孩子们在绿地上花费的时间更少。 假设2.2：绿地利用通过以下途径影响心理健康和幸福感 睡眠行为(持续时间、时间、规律性)使用活动记录仪进行评估。目标3.探索性 瞄准。绿色空间、表观遗传学、睡眠和幸福。探索潜在的表观遗传学 绿地对儿童睡眠和健康的贡献。探索性假设1.1。 高绿地和低绿地使用者之间的差异DNA甲基化模式可能不同 与压力反应、睡眠不足、光照或体力活动相关的基因。 我们将在罗德岛工作，该岛目前正在扩大通往树冠的道路 在整个州--这在美国是一个独特的称谓。因此，健康和政策 我们的研究的影响是及时的，可以对其他感兴趣的国家产生影响 探索利用绿地改善儿童及其家庭健康。

The WHO indicates 10% to 20% of children and adolescents have pediatric mental health disorders, contributing to a projected worldwide economic burden of $6 trillion by 2030. In RI, approximately 19% of children under the age of 17 have mental health challenges that can adversely affect their development, education, peer relationships, and physical health. Sleep is an increasingly recognized contributor to mental health and well-being. In children, inadequate sleep has been linked to diminished mental and physical health. Exposure to greenspace, broadly defined as various forms of vegetation, has been shown to confer numerous health benefits. In this study, we propose to explore the association between exposure to greenspace and mental health outcomes in elementary school children. Aim 1. Sleep and greenspace. Determine how green space utilization (GPS-derived measures of daily activity and environmental features) is related to sleep (duration, timing, regularity) in children. Hypothesis 1.1 Children spending more time in greenspace as derived by GPS (i.e., utilization) will have earlier, longer and more regular sleep than children spending less time in greenspace. Hypothesis 1.2. Greenspace utilization will influence sleep through increased light exposure, higher levels of physical activity measured using accelerometry, and lower levels of stress measured by IL-1 beta. Aim 2. Mental health, greenspace and sleep. Determine whether greenspace utilization is associated with mental health and wellbeing via sleep behaviors. Hypothesis 2.1: Children spending more time in greenspace will have fewer mental health symptoms as measured by validated PROMIS® measures of anxiety, cognitive functioning, psychological stress and wellbeing compared to children spending less time in greenspace. Hypothesis 2.2: Greenspace utilization will influence mental health and well-being through sleep behavior (duration, timing, regularity) assessed using actigraphy. Aim 3. Exploratory Aim. Greenspace, epigenetics, sleep and wellbeing. Explore the potential epigenetic contribution of greenspace on sleep and wellbeing in children. Exploratory Hypothesis 1.1. Patterns of differential DNA methylation between high and low greenspace users may differ in genes associated with stress response, inadequate sleep, light exposure, or physical activity. We will work in Rhode Island, which is currently engaged in expanding access to tree-canopy across the entire state – a unique designation in the US. Thus, the health and policy implications of our study is timely, and can have implications for other states interested in exploring the use green space to improve health among children and their families.
