项目摘要

DESCRIPTION (provided by applicant): Obesity is perhaps the greatest health threat facing the US, and policy-based prevention approaches must be part of the solution. In preschool-aged children, regular exercise decreases obesity risk, improves motor skills, and enhances cardiovascular function. With nearly three quarters of young children in some form of non- parental child care and 56% in center-based child care, the child care setting may be a key to reversing disturbing trends in physical activity and obesity. Massachusetts (MA) recently implemented a new policy requiring 60 minutes of daily physical activity for all children in child care. A narrow window of opportunity now exists to evaluate this new policy, which will affect over 2,000 child care centers caring for nearly 40,000 children in MA. We intend to leverage this natural experiment to assess the effectiveness of the new policy by measuring physical activity in children attending child care center before and after the policy takes effect, both in MA and Rhode Island (RI), a comparison state. Child care is not regulated by the federal government-each individual state is responsible for regulating its child care centers. Though 2 states, Delaware and Alaska, have recently enacted new policies requiring 60 minutes of daily physical activity for all children in child care, they have not been evaluated for effectiveness. The proposed study provides a unique opportunity to evaluate this physical activity policy. The primary aim of the study is to determine the extent to which the new policy in MA, compared with RI, increases physical activity in 3- to 5-year old children in child care. We will use a quasi-experimental two-group pre-test/post-test design to assess physical activity in a sample of children attending child care centers before and after the policy takes effect. This evaluation is already underway. We collected 3 rounds of pre-policy physical activity data over the course of 1.5 years (fall 2008, spring 2009, and fall 2009). We focused our data collection efforts on Boston, MA and Providence, RI and measured physical activity in a sample of children attending 40 child care centers (20 per city). We collected both observation (n=360 children) and accelerometer (n=41 children) data to assess the physical activity levels of children, focusing on total minutes children engage in moderate to vigorous physical activity. In this proposal, we seek funding to support post- policy physical activity data collection to complete our evaluation of this natural experiment.

描述（由申请人提供）：肥胖可能是美国面临的最大健康威胁，基于政策的预防方法必须是解决方案的一部分。在学龄前儿童中，定期运动会降低肥胖风险，提高运动技能并增强心血管功能。有近四分之三的幼儿以某种形式的非父母儿童保育，在中心的儿童保育中有56％的幼儿，儿童保育环境可能是扭转运动和肥胖趋势令人不安的关键。马萨诸塞州（马萨诸塞州）最近实施了一项新政策，要求所有儿童在儿童保育中进行60分钟的身体活动。现在有一个狭窄的机会窗口来评估这一新政策，这将影响2,000多个照顾马萨诸塞州近40,000名儿童的托儿中心。我们打算利用这项自然实验来评估新政策的有效性，通过在政策生效之前和之后，在MA和Rhode Island（RI）（一个比较状态）生效之前和之后的儿童体育活动，这是一个比较状态。托儿保育不受联邦政府的每个州的监管，负责监管其儿童保育中心。尽管有两个州，特拉华州和阿拉斯加，最近制定了新的政策，要求所有儿童在儿童保育中进行60分钟的日常体育锻炼，但尚未对他们的有效性进行评估。拟议的研究为评估这种体育活动政策提供了独特的机会。该研究的主要目的是确定与RI相比，MA的新政策在多大程度上增加了3至5岁儿童在儿童保育中的体育锻炼。我们将使用准实验性的两组预测试/测试后设计来评估政策生效之前和之后参加儿童中心的儿童样本中的身体活动。此评估已经在进行中。我们在1。5年（2008年秋季，2009年春季和2009年秋季）中收集了3轮前体育活动数据。我们将数据收集工作集中在马萨诸塞州波士顿和RI的波士顿，并测量了参加40个儿童保育中心（每个城市20个）的儿童样本中的体育活动。我们同时收集了观察力（n = 360个儿童）和加速度计（n = 41个儿童）数据，以评估儿童的体育锻炼水平，重点关注儿童进行中等至剧烈的体育锻炼。在此提案中，我们寻求资金来支持政策后的体育活动数据收集，以完成我们对这项自然实验的评估。
