Research in children in North America using brain scanning has shown that the brain develops less well and has a smaller surface area in children of families with less income. This result was not found in a study from Norway, where there is greater socioeconomic equality. Our own research has shown that being poor as a child is associated with more brain abnormalities in later life, which are associated with depression and dementia. Countries such as India are experiencing a rapid rise in what were considered "Western diseases", such as diabetes, combined with an increase in older people. In addition, there remain significant disparities in socioeconomic circumstance, access to education and healthcare. Researchers in the UK, in Mysore and in Mumbai have established groups of normal people (cohorts) at different ages and from different socioeconomic circumstances that have already provided much evidence on the early life origins of later life diseases, such as heart disease and diabetes. Here we will carry out work that will pave the way for a future large-scale study of mental health and thinking (cognitive) abilities in these groups. Concentrating on the Mysore groups in this application, we plan four projects that will help us design our future project to include people in Mysore and Mumbai. 1. We will invite a small number of the younger and older Mysore cohorts to have a brain scan first to find out how acceptable scanning is for them and secondly as a pilot study to test whether early life circumstances influence measurable changes on brain scans. We will investigate what factors in early life (such as your father's job, your birth weight) predict brain scan appearances. 2. By speaking with participants we will find out what people who are part of these informative cohorts think about volunteering for brain scans, blood tests and new computer tests of their thinking (cognitive) abilities. We will ask them how they view keeping information about them on a computer and their opinions of combining this information with other health and education information about them. We will also take account of local permissions, participants' and researchers' views on creation of a future database that allows their information to be securely stored, transferred between institutions in India and anonymously available to future researchers. Such a collection of information would grow over time and allow future research to answer our question about the impact of early life environment on important mental health outcomes.3. Provided participants agree, we will collect blood samples, cheek scrape samples, repeat tests of thinking abilities and depressive symptoms to add to existing research records and to allow us to calculate how many scans and tests would be needed in a future large-scale study to provide meaningful information. We will also take account of local permissions, participants' and researchers' views on creation of a future database that allows this information to be securely stored, transferred between institutions in India and anonymously available to future researchers. 4. We will host a workshop at the University of Aberdeen for investigators from India and Aberdeen to discuss and plan analysis of the extensive information available in these participants and how we best design a data analysis plan, based on pilot data, existing expertise on "big data" approaches and meaningful statistical analysis for a future large-scale application to address our research question.The work we propose here will provide the preparatory work for a future study to discover what aspects of early life environment can be modified to reduce mental illness and cognitive decline in India. This addresses three of the Sustainable Development Goals: i) Goal 3-to ensure healthy lives and promote well-being for all at all ages; ii) Goal 4-to promote lifelong learning opportunities for all; iii) Goal 10-to reduce inequalities.

对北美儿童进行的大脑扫描研究表明，收入较低家庭的儿童大脑发育较差，表面积较小。挪威的一项研究并未发现这一结果，因为挪威的社会经济平等程度更高。我们自己的研究表明，童年时期的贫困与以后生活中更多的大脑异常有关，而这些异常又与抑郁症和痴呆症有关。印度等国家正在经历糖尿病等所谓“西方疾病”的迅速增加，以及老年人口的增加。此外，社会经济环境、教育和医疗保健的机会仍然存在显着差异。英国、迈索尔和孟买的研究人员建立了不同年龄和不同社会经济环境的正常人群体（队列），这些群体已经为心脏病和糖尿病等晚年疾病的早期起源提供了很多证据。在这里，我们将开展的工作将为未来对这些群体的心理健康和思维（认知）能力进行大规模研究铺平道路。我们重点关注此应用程序中的迈索尔群体，计划了四个项目，这将帮助我们设计未来的项目，以包括迈索尔和孟买的人们。 1. 我们将邀请少数年轻和年长的迈索尔人群首先进行脑部扫描，以了解扫描对他们的可接受程度，其次作为试点研究，测试早期生活环境是否影响脑部扫描的可测量变化。我们将研究早期生活中的哪些因素（例如你父亲的工作、你的出生体重）可以预测脑部扫描的表现。 2. 通过与参与者交谈，我们将了解这些信息丰富的群体中的人们对志愿进行脑部扫描、血液测试和新的计算机思维（认知）能力测试的看法。我们将询问他们如何看待在计算机上保存有关他们的信息，以及他们对将这些信息与有关他们的其他健康和教育信息结合起来的看法。我们还将考虑当地的许可、参与者和研究人员对创建未来数据库的看法，该数据库允许安全地存储他们的信息，在印度的机构之间传输并匿名地供未来的研究人员使用。这样的信息收集将随着时间的推移而增长，并允许未来的研究回答我们关于早期生活环境对重要心理健康结果的影响的问题。3。如果参与者同意，我们将收集血液样本、脸颊刮擦样本，重复测试思维能力和抑郁症状，以添加到现有的研究记录中，并允许我们计算在未来的大规模研究中需要多少次扫描和测试才能提供有意义的信息。我们还将考虑当地的许可、参与者和研究人员对创建未来数据库的看法，该数据库允许安全地存储这些信息，在印度的机构之间传输并以匿名方式提供给未来的研究人员。 4. 我们将在阿伯丁大学为来自印度和阿伯丁的研究人员举办一次研讨会，讨论和计划对这些参与者提供的广泛信息进行分析，以及如何根据试点数据、现有的“大数据”方法专业知识和有意义的统计分析来设计数据分析计划，以便未来大规模应用来解决我们的研究问题。我们在此提出的工作将为未来的研究提供准备工作，以发现早期生活环境的哪些方面可以被修改 减少印度的精神疾病和认知能力下降。这涉及三个可持续发展目标： i) 目标 3——确保健康的生活并促进各年龄段所有人的福祉； ii) 目标 4——促进所有人终身学习的机会； iii) 目标 10——减少不平等。
