DESCRIPTION (provided by applicant): The "graying of America" represents an unprecedented demographic trend whereby the population of Americans aged 55 or older is increasing rapidly. Therefore, it is important to identify the mental health needs of older Americans as they move toward later life. By understanding the incidence, prevalence, correlates, and treatment needs of psychiatric disorders among older adults, researchers can make greater inroads to more efficiently direct limited preventive and treatment resources. Few investigations have an epidemiological sample of older adults to permit adequate estimation of the patterns and correlates of geriatric psychiatric disorders, including those disorders that are "sub-threshold" and do not meet established diagnostic criteria but may be extremely disabling. Physical illnesses, which may be extremely stressful psychosocial events, are also more present during older adulthood, and additional information is lacking regarding the onset of psychiatric disorders resulting from medical conditions. This RO3 application, submitted by a new investigator, seeks to overcome these limitations by bringing together an interdisciplinary team of epidemiological and clinical researchers to focus on geriatric mental health. This application proposes secondary analyses of the subset of older adults (n=13,420) within the National Epidemiologic Survey on Alcohol and Related Conditions (2001-2002) (NESARC) to examine the broader issues of incidence, prevalence, correlates, and treatment of mental disorders among older adults (aged 55 or older). The NESARC is unique because it contains comprehensive assessments of psychiatric disorders in a nationally representative sample of older adults. The specific aims are to: (1) Estimate the prevalence and demographic correlates (e.g., marital status, gender, race, employment, and education) of psychiatric mood and anxiety disorders during older adulthood (aged 55 or older) for the following the disorder subtypes: (a) independent of medical or substance abuse (IDs) and (b) medically induced disorders (MIDs); We will also examine subthreshold disorders within each disorder group. (2) Examine the demographic and clinical factors (e.g. symptom profile, number and length of episodes) that differentiate the structure of psychiatric disorder subtypes among older adults based on: (a) patterns of co-morbidity (e.g. pure versus co-morbid) and (b) early (i.e. less than age 55) versus late onset (i.e. age 55 or older) disorders; and (3) Estimate the patterns of treatment utilization among disorder subtypes. Information learned from this study will help assess the degree to which unique screening and intervention efforts are needed across disorder subtypes. Issues addressed in this proposal are in concert with the scientific agenda for mental health and aging research promoted by National Institute of Mental Health, Mental Illnesses in Older Adults (PA-03-014).

描述（由申请人提供）：“美国老龄化”代表了一种前所未有的人口趋势，其中55岁或以上的美国人口正在迅速增加。因此，重要的是要确定美国老年人的心理健康需求，因为他们走向晚年。通过了解老年人精神疾病的发病率，患病率，相关因素和治疗需求，研究人员可以更有效地指导有限的预防和治疗资源。很少有调查有老年人的流行病学样本，以允许充分估计老年精神疾病的模式和相关性，包括那些疾病是“亚阈值”，不符合既定的诊断标准，但可能是极端残疾。身体疾病，可能是压力极大的心理社会事件，也更多地出现在老年时期，而且缺乏关于医疗条件导致的精神疾病发作的更多信息。由一位新的研究人员提交的RO 3申请旨在通过汇集流行病学和临床研究人员的跨学科团队来克服这些限制，重点关注老年心理健康。本申请建议对国家酒精及相关疾病流行病学调查（2001-2002年）（NESARC）中的老年人（n= 13，420）进行二次分析，以研究老年人（55岁或以上）精神障碍的发病率、患病率、相关因素和治疗等更广泛的问题。NESARC是独一无二的，因为它包含了对全国具有代表性的老年人样本中精神疾病的全面评估。具体目标是：（1）估计流行率和人口统计学相关因素（例如，婚姻状况、性别、种族、就业和教育）的精神情绪和焦虑障碍在老年人（55岁或以上）的以下障碍亚型：（a）独立于药物或物质滥用（ID）和（B）医学诱导的障碍（MID）;我们还将检查每个障碍组内的阈下障碍。(2)检查人口统计学和临床因素（例如症状特征、发作次数和持续时间），根据以下方面区分老年人中精神障碍亚型的结构：（a）共病模式（例如，单纯与共病）和（B）早期（即小于55岁）与晚发性（即55岁或以上）病症的比较;和（3）估计病症亚型之间的治疗利用模式。从这项研究中了解到的信息将有助于评估在何种程度上需要独特的筛查和干预工作，在疾病亚型。本提案中所述问题与国家心理健康研究所推动的心理健康和老龄化研究的科学议程一致，老年人心理疾病（PA-03-014）。
