DESCRIPTION (provided by applicant): In this revised application, we addressed the IRG's concerns: we clarified the number/type of assessments on the 3 subject groups; proposed a further Hypothesis that mirrors better the use of childhood archival data about probands and their sibs; added ICAM-1 to our biological markers; and responded to various other concerns. Our study focuses on depression and coronary heart disease (CHD), which are enormous public health problems across the world. Depression not only predicts new onset CHD, and morbidity, and mortality in those with existing CHD but also is associated with behavioral risk factors (e.g. smoking, being sedentary) for eventual CHD. Although the depression-CHD link is well established, the causal role of depression is still being debated, and its most "cardiotoxic" features are yet to be confirmed. Notably, although both depression and CHD often originate in the pre-adult years, few studies have examined their association with behavioral CHD risk factors in a developmental context. We propose to assess 3 established samples of young adults in Hungary: a) probands (n=325), whom we have followed since childhood, when they had their first episode of major depression around the mean age of 9 years, b) never-depressed siblings of probands (n=325), and c) normal peer controls (n=155). We recently reported that: a) proband families have elevated rates of parental CV disease, b) by adolescence (mean age=17 years), being a proband predicted increased rates of behavioral risk factors for CHD (e.g., smoking, being sedentary), and c) rates of behavioral risk factors were highest among probands, lowest among controls, and intermediate among never depressed siblings of probands. The goal of the proposed study is to assess, for the first time, traditional biological risk factors (e.g., LDL cholesterol, blood pressure), along with behavioral risk factors, and several markers of CHD risk: pulse wave velocity, interleukin-6 and C-reactive protein (inflammation), ICAM-1 (endothelial function), and the metabolic syndrome. Our hypotheses address the levels of CHD risk markers as a function of subject group, the role of behavioral risk factors in adolescence in the link between depression and preclinical physiological outcomes, the impact of developmental trajectories of stress and risk variables on physiological outcomes among probands-sibs, and the most "cardiotoxic" clinical features of depression. Our extensive archival data on subjects' psychiatric history, family stress events, parental history of cardiovascular disease, socio-demographic variables, and various behavioral risk factors for CHD will yield a unique characterization of the unfolding relationships among depression, behavioral risk factors, and early markers of CHD risk. The sibling design will help isolate the contribution of depression to early markers of CHD risk by controlling for the adverse health impact of several family-based variables. Given the public health burden posed by depression and CHD, their study in young adults is particularly warranted, because risk factors and/or preclinical signs of CHD risk may be easier to modify earlier, rather than later, in the lifespan.

描述(由申请人提供)：在这份修订后的申请中，我们解决了IRG关注的问题：我们澄清了3个受试组的评估数量/类型；提出了更好地反映关于先证者及其兄弟姐妹的童年档案数据使用的进一步假设；将ICAM-1添加到我们的生物标记中；并回应了各种其他关切。我们的研究重点是抑郁症和冠心病(CHD)，这是全球范围内的巨大公共健康问题。抑郁不仅预示着新的冠心病发病、现有冠心病患者的发病率和死亡率，而且还与最终冠心病的行为危险因素(如吸烟、久坐)有关。尽管抑郁症与CHD之间的联系已经确立，但抑郁症的因果作用仍在争论中，其最“心脏毒性”的特征还有待证实。值得注意的是，尽管抑郁症和CHD通常都起源于成年前几年，但很少有研究在发育背景下检查它们与行为CHD风险因素的关系。我们建议评估匈牙利3个已确定的年轻人样本：a)先证者(n=325)，我们从童年开始跟踪他们，他们在平均9岁左右第一次出现重度抑郁症，b)先证者的从未抑郁的兄弟姐妹(n=325)，以及c)正常同龄人对照组(n=155)。我们最近报道：a)先证者家庭父母心血管疾病的发病率较高，b)青春期(平均年龄=17岁)，作为先证者预测冠心病行为风险因素(如吸烟、久坐)的比率增加，以及c)行为风险因素在先证者中最高，在对照组中最低，在先证者从未抑郁的兄弟姐妹中居中。这项拟议研究的目标是首次评估传统的生物风险因素(如低密度脂蛋白、血压)，以及行为风险因素，以及冠心病风险的几个标记物：脉搏波速度、白细胞介素6和C反应蛋白(炎症)、ICAM-1(内皮功能)和代谢综合征。我们的假设涉及CHD风险标记物的水平作为受试者组的函数，青春期行为风险因素在抑郁症和临床前生理结果之间的联系中的作用，压力和风险变量的发展轨迹对先证者-同胞之间生理结果的影响，以及抑郁症最“心脏毒性”的临床特征。我们关于受试者的精神病史、家庭压力事件、父母心血管病史、社会人口学变量和各种冠心病行为风险因素的广泛档案数据将对抑郁症、行为风险因素和冠心病风险的早期标记物之间的关系产生独特的表征。同胞设计将通过控制几个以家庭为基础的变量对健康的不利影响，帮助分离抑郁症对冠心病风险早期标志的贡献。考虑到抑郁症和冠心病造成的公共健康负担，他们在年轻人中的研究特别有必要，因为冠心病风险的风险因素和/或临床前迹象可能更容易在生命周期的早期而不是后期进行修改。
