DESCRIPTION (provided by applicant): The purpose of this study is to examine the impact of television on adolescent sleep/wake patterns in the context of a controlled experiment with Vietnamese villages lacking both television and electricity. Accumulating evidence indicates that increasing numbers of adolescents are going to bed later and getting by on less than optimal sleep in most areas of the globalizing world. The convergence of maturational processes with media access and related social changes appear to play a role in these trends. The research plan builds on a unique opportunity to identify social-ecological factors that contribute to the development of adolescent sleep and circadian changes within a randomized experimental design. Introducing television will combine biological and social stimuli via access to lighted screens and engaging stimuli, with altered social interactions around television watching. We will examine sleep patterns and associated neurobehavioral and health statuses in all adolescents aged 12-18 (n=107) residing in a matched pair of experimental television-receiving and control villages. Actigraphy in adolescents will be combined with measures of pubertal status, behavioral alertness, sleep quality, school attendance and performance, and mental and physical health. The study design puts adolescent sleep behavior in social context at 3 levels of analysis, family (household), community (village), and culture (Vietnamese Tai). Household measures include adolescent and parent sleep habits, daily routines, perceived well-being, and GPS tracking to gauge time at key sites (television, home, school, fields), time together, and ranging distance. Village-wide data on each community member are collected in the main project, which this study will join. Measures relevant to our hypotheses include amount of television viewing, GPS-mapped social geography, demographics, and perceived stress, life satisfaction and social status. Ongoing ethnography probes sleep attitudes, practices, and meanings. This research will provide the first direct test for causal links between television and changes in adolescent sleep. We test whether television-watching youth show changed sleep timing, amount, and quality; whether puberty, gender, and parental monitoring influence these effects; and whether school performance and health indices suffer. Findings will directly address questions about whether and how developmental processes (puberty) interact with social ecology (community-level television introduction and household-level conditions) to produce adolescent vulnerability to sleep restriction and disruption, and with what functional and health consequences. Previous research on these questions has been hampered by inability to establish causal influences: we capitalize on a randomized experiment to overcome that difficulty. PUBLIC HEALTH RELEVANCE: Sleep has become the focus for a compelling set of health concerns as growing evidence links the very high rates of sleep deprivation in adolescents with an enormous array of negative health consequences including accidents, metabolic effects and rising obesity, impairments in mood and learning, mental health problems, and substance use. This proposal builds on a randomized experimental design to measure the causal links between television and changes in adolescent sleep. Findings will help identify key factors in adolescent vulnerability to sleep inadequacy and associated health issues.

描述（由申请人提供）：本研究的目的是检查电视对青少年睡眠/唤醒模式的影响，在受控实验的背景下，越南村庄缺乏电视和电力。积累的证据表明，在全球化世界的大多数领域，越来越多的青少年人数将在以后上床睡觉，并且无法获得最佳睡眠。成熟过程与媒体访问和相关社会变化的融合似乎在这些趋势中起作用。该研究计划以独特的机会为基础，以确定社会生态因素，这有助于在随机实验设计中发展青少年睡眠和昼夜节律变化。介绍电视将通过进入照明屏幕和引人入胜的刺激结合生物学和社交刺激，并在电视观看周围进行社交互动的改变。我们将研究居住在一对匹配的实验性电视收射和控制村庄中的12-18岁（n = 107）的青少年中的睡眠模式和相关的神经行为和健康状况。青少年的动作学将与青春期状态，行为警觉，睡眠质量，学校出勤和表现以及心理和身体健康的措施相结合。该研究设计使青少年的睡眠行为在社会环境中处于三个分析，家庭（家庭），社区（乡村）和文化（越南泰）的层次。家庭措施包括青少年和父母的睡眠习惯，日常工作，感知的幸福感以及GPS跟踪到关键站点（电视，家庭，学校，田野），时间和时间距离。在主要项目中收集了每个社区成员的乡村范围数据，这项研究将加入。与我们的假设相关的措施包括电视观看数量，GPS映射的社会地理，人口统计以及感知到的压力，生活满意度和社会地位。正在进行的民族志探测睡眠态度，实践和含义。这项研究将为电视与青少年睡眠变化之间的因果关系提供首次直接测试。我们测试了观看电视青年节目是否改变了睡眠时间，数量和质量；青春期，性别和父母监测是否会影响这些影响；以及学校表现和健康指数是否受到影响。调查结果将直接解决有关是否以及如何与社会生态（社区电视介绍和家庭水平条件）相互作用的发展过程（青春期），以产生青少年的睡眠限制和干扰以及功能和健康后果。对这些问题的先前研究受到了无法建立因果影响的阻碍：我们利用了一个随机实验来克服这一困难。 公共卫生相关性：睡眠已成为一系列令人信服的健康问题的重点学习，心理健康问题和药物使用。该建议基于随机实验设计，以测量电视与青少年睡眠变化之间的因果关系。调查结果将有助于确定青少年脆弱性不足和相关健康问题的关键因素。
