    背景:焦虑和注意力缺陷/多动障碍(ADHD)的症状从童年到青春期具有前瞻性相关。然而,ADHD的两个维度-注意力不集中和多动-冲动-是否与焦虑有差异,以及这些关系中是否存在发育和性别/性别差异尚不清楚.
    方法:每两年对两个4至16岁的挪威儿童(N=1,077;49%的女孩)进行评估,并进行诊断性父母访谈,以评估焦虑和ADHD的症状。使用随机截距交叉滞后面板模型分析数据,调整所有未观察到的时不变混杂效应。
    结果:在女孩中,注意力不集中,但不是多动-冲动,预测2年后所有时间点的焦虑增加,12岁和14岁时焦虑增加,预测注意力不集中而不是多动-冲动增加。在男孩中,在6岁和8岁时,多动-冲动增加,但注意力不集中,预测2年后焦虑增加,而焦虑的增加并不能预测注意力不集中或多动-冲动的增加。
    结论:ADHD的两个维度与焦虑有差异,而且这种关系是有性别的.在女孩中,注意力不集中可能参与整个儿童期和青春期焦虑的发展,而焦虑可能导致女孩在青春期早期开始出现更多的注意力不集中.在男孩中,多动-冲动可能参与早期学校焦虑的发展。有效治疗女孩的注意力不集中症状可以降低所有时间点的焦虑风险,而解决焦虑可能会减少青春期的注意力不集中。同样,治疗多动-冲动可能会降低男孩在儿童后期(8-10岁)的焦虑风险。
    BACKGROUND: Symptoms of anxiety and attention-deficit/hyperactivity disorder (ADHD) are prospectively related from childhood to adolescence. However, whether the two dimensions of ADHD-inattention and hyperactivity-impulsivity-are differentially related to anxiety and whether there are developmental and sex/gender differences in these relations are unknown.
    METHODS: Two birth cohorts of Norwegian children were assessed biennially from ages 4 to 16 (N = 1,077; 49% girls) with diagnostic parent interviews used to assess symptoms of anxiety and ADHD. Data were analyzed using a random intercept cross-lagged panel model, adjusting for all unobserved time-invariant confounding effects.
    RESULTS: In girls, increased inattention, but not hyperactivity-impulsivity, predicted increased anxiety 2 years later across all time-points and increased anxiety at ages 12 and 14 predicted increased inattention but not hyperactivity-impulsivity. In boys, increased hyperactivity-impulsivity at ages 6 and 8, but not increased inattention, predicted increased anxiety 2 years later, whereas increased anxiety did not predict increased inattention or hyperactivity-impulsivity.
    CONCLUSIONS: The two ADHD dimensions were differentially related to anxiety, and the relations were sex-specific. In girls, inattention may be involved in the development of anxiety throughout childhood and adolescence and anxiety may contribute to girls developing more inattention beginning in early adolescence. In boys, hyperactivity-impulsivity may be involved in the development of anxiety during the early school years. Effective treatment of inattention symptoms in girls may reduce anxiety risk at all time-points, while addressing anxiety may decrease inattention during adolescence. Similarly, treating hyperactivity-impulsivity may reduce anxiety risk in boys during late childhood (at ages 8-10).

    背景:青少年闲暇时间体育活动的参与有益于体育活动习惯和以后生活中的健康结果。然而,尚不清楚某些类型的休闲时间体育活动是否以不同的方式有助于这些益处;这些知识可以增强公共卫生工作。本系统综述旨在综合儿童和青少年休闲时间体育活动与成年体育活动行为和健康结果之间纵向关联的证据。
    方法:从开始到2022年7月,对五个数据库进行了系统的文献搜索。英语,至少收集两个时间点数据的同行评审观察性研究符合纳入条件.我们纳入了调查儿童和青少年参与休闲时间体育活动类型之间关联的研究(即,5-18岁),和身体活动,心理健康,或成年期的心血管结局(即,≥18岁)。
    结果:14项研究纳入了综述,在五个国家共进行了34,388次观察。青春期跑步与男女成年后体力活动增加有关,而运动参与仅与男性体育锻炼的增加有关。青少年团队运动参与与成年早期抑郁的几率降低有关,对焦虑症有不同的发现。在观察到与未来的身体活动或健康结果益处相关之前,有初步证据表明参与某些活动的最低阈值要求。
    结论:初步研究结果表明,青少年参加休闲体育活动对终生行为和健康的益处似乎与所从事的活动类型有关,两性之间的潜在差异。从童年到成年的纵向研究非常罕见,这些发现为优化终身健康和体育活动参与的公共卫生策略提供了重要见解。

    BACKGROUND: Youth leisure-time physical activity participation benefits physical activity habits and health outcomes later in life. However, it is unknown if certain types of leisure-time physical activity contribute to these benefits in different ways; this knowledge could enhance public health efforts. This systematic review aimed to synthesise evidence of the longitudinal associations between childhood and adolescent leisure-time physical activity on adulthood physical activity behaviours and health outcomes.
    METHODS: A systematic search of the literature was conducted across five databases from inception to July 2022. English, peer-reviewed observational studies with a minimum of two timepoints of data collection were eligible for inclusion. We included studies that investigated the association between participation in leisure-time physical activity types in children and adolescents (i.e., 5-18 years), and physical activity, mental health, or cardiovascular outcomes in adulthood (i.e., ≥ 18 years).
    RESULTS: Fourteen studies were included in the review, totalling 34,388 observations across five countries. Running in adolescence was associated with increased adulthood physical activity in both sexes, while sports involvement was associated with an increase in physical activity in males only. Adolescent team sports participation was associated with reduced odds of early adulthood depression, with varying findings for anxiety disorders. There was preliminary evidence of minimum threshold requirements for participation in certain activities before associations with future physical activity or health outcome benefits were observed.
    CONCLUSIONS: Preliminary findings suggest that the lifelong behavioural and health benefits of adolescent participation in leisure-time physical activity appear to be related to the type of activity undertaken, with potential differences between sexes. With the rarity of longitudinal studies spanning from childhood into adulthood, these findings provide important insights for public health strategies to optimise lifelong health and physical activity participation.

    背景:儿童家庭结构被认为在人的健康和福利中起作用。这项研究调查了成人健康行为的纵向变化与儿童家庭结构之间的关系。
    方法:来自北芬兰出生队列1966年问卷,我们收集了14岁时儿童家庭结构的数据(“双亲家庭”,\'一个父母不住在家里/没有父亲的信息\',和\'父亲或母亲去世\'),和健康行为(吸烟,31岁和46岁的饮酒和体力活动状况)。我们使用多项逻辑回归模型来估计儿童家庭结构与31至46年健康行为(四类变量)之间的纵向变化之间的未调整和调整关联。
    结果:在研究样本中(n=5431;55.5%的女性),7.1%的后代代表在“父母一方不在家/没有父亲信息”亚组中,6.3%在“父亲或母亲去世”分组中,86.6%在“双亲家庭”中。“一个父母不在家/没有父亲的信息”后代在成年后的两次吸烟(调整后OR2.19,95%CI1.70-2.81)和大量饮酒(调整后OR1.99,95%CI1.25-3.16)。相对于不吸烟或不大量饮酒,并与“双亲家庭”的后代进行比较。我们发现儿童期家庭结构与成年期体力活动状况变化之间没有统计学上的显着关联。
    结论:我们的研究结果表明,单亲家庭的后代尤其应该在生命早期得到支持,以减少他们在成年期出现不健康行为的风险。
    BACKGROUND: Childhood family structure is considered to play a role in person\'s health and welfare. This study investigated the relationships between the longitudinal changes of adult health behaviours and childhood family structure.
    METHODS: From Northern Finland Birth Cohort 1966 questionnaires, we collected data on childhood family structure at the age of 14 (\'two-parent family\', \'one parent not living at home/no information on father\', and \'father or mother deceased\'), and on health behaviours (smoking, alcohol consumption and physical activity status) at the ages of 31 and 46. We used the multinomial logistic regression model to estimate the unadjusted and adjusted associations between childhood family structures and the longitudinal changes between 31 and 46 years of health behaviours (four-category variables).
    RESULTS: Of the study sample (n = 5431; 55.5% females), 7.1% of the offspring were represented in the \'One parent not living at home/no information on father\' subgroup, 6.3% in the \'Father or mother deceased\' subgroup and 86.6% in the \'Two-parent family\'. \'One parent not living at home/no information on father\' offspring were approximately twice as likely to smoke (adjusted OR 2.19, 95% CI 1.70-2.81) and heavily consume alcohol (adjusted OR 1.99, 95% CI 1.25-3.16) at both times in adulthood, relative to not smoking or not heavily consume alcohol, and compared with \'two-parent family\' offspring. We found no statistically significant associations between childhood family structure and physical activity status changes in adulthood.
    CONCLUSIONS: Our findings suggest that the offspring of single-parent families in particular should be supported in early life to diminish their risk of unhealthy behaviours in adulthood.

    在过去的几十年里,美国男性的有偿工作已经从高度稳定和连续性的状态转变为更加不稳定和不稳定的状态。尽管如此,整个成年期的全职工作仍然是现代美国男性的假定标准。作者使用全国青年纵向调查“全国青年纵向调查-1979年队列”调查了男性劳动力经历的多样性,并确定了男性就业时间的六个多轨迹,失业,从27岁到49岁的劳动力中。作者确定了一个稳定工作的多轨迹,三是失业或失业时间增加,增加稳定的工作之一,和间歇性工作之一。与传统假设相反,只有41%的男性遵循连续的轨迹,在他们的主要收入年份期间的高就业率。这表明大多数男人没有达到“理想的工人规范”,“对研究和政策如何概念化男性的工作经历提出了启示。
    Over the past several decades, U.S. men\'s paid work has transformed from a state of high stability and continuity to a state of increased instability and precarity. Despite this, full-time employment throughout adulthood remains the presumed standard for modern American men. The authors investigated the diversity of men\'s workforce experiences using the National Longitudinal Survey of Youth \"National Longitudinal Survey of Youth - 1979 cohort\" and identified six multitrajectories of men\'s time spent employed, unemployed, and out of the labor force from ages 27 to 49. The authors identified one multitrajectory of steady work, three of increasing unemployment or time out of work, one of increasing steady work, and one of intermittent work. Contrary to conventional assumptions, only 41 percent of men followed a trajectory of continuous, high employment over the duration of their prime earning years. This suggests that most men do not achieve the \"ideal worker norm,\" raising implications for how research and policy conceptualize men\'s work experiences.

    生物年龄使用生物卫生学信息来捕捉一个人与年龄相关的不良后果风险。MetaboAge和MetaboHealth是基于代谢组学的生物年龄生物标志物,在实际年龄和死亡风险方面进行了培训,分别。生活方式因素在时间和生物年龄差异的程度上有所贡献。生活方式因素与MetaboAge和MetaboHealth,这些关联中潜在的性别差异,以及MetaboAge和MetaboHealth对生活方式改变的敏感性尚未被研究。在Doetinchem队列研究的24,332名中年参与者中,使用线性回归分析和混合效应模型来检查缩放生活方式因素与缩放MetaboAge和MetaboHealth的横截面和纵向关联,鹿特丹研究,和英国生物银行。在队列中进行随机效应荟萃分析。重复的代谢组学测量在Doetinchem队列研究中有十年的间隔,在英国生物银行中有五年的间隔。在第一项纳入MetaboAge和MetaboHealth纵向信息的研究中,我们展示了当前吸烟之间的关联,睡眠≥8小时/天,BMI较高,较大的腰围与较高的MetaboHealth相关,后两者也具有较高的MetaboAge。此外,坚持饮食和体力活动指南与MetaboHealth呈负相关.最后,我们观察到饮酒与MetaboHealth之间的相关性存在性别差异.
    Biological age uses biophysiological information to capture a person\'s age-related risk of adverse outcomes. MetaboAge and MetaboHealth are metabolomics-based biomarkers of biological age trained on chronological age and mortality risk, respectively. Lifestyle factors contribute to the extent chronological and biological age differ. The association of lifestyle factors with MetaboAge and MetaboHealth, potential sex differences in these associations, and MetaboAge\'s and MetaboHealth\'s sensitivity to lifestyle changes have not been studied yet. Linear regression analyses and mixed-effect models were used to examine the cross-sectional and longitudinal associations of scaled lifestyle factors with scaled MetaboAge and MetaboHealth in 24,332 middle-aged participants from the Doetinchem Cohort Study, Rotterdam Study, and UK Biobank. Random-effect meta-analyses were performed across cohorts. Repeated metabolomics measurements had a ten-year interval in the Doetinchem Cohort Study and a five-year interval in the UK Biobank. In the first study incorporating longitudinal information on MetaboAge and MetaboHealth, we demonstrate associations between current smoking, sleeping ≥8 hours/day, higher BMI, and larger waist circumference were associated with higher MetaboHealth, the latter two also with higher MetaboAge. Furthermore, adhering to the dietary and physical activity guidelines were inversely associated with MetaboHealth. Lastly, we observed sex differences in the associations between alcohol use and MetaboHealth.

    尽管手术和治疗方法取得了进展,高级别浆液性卵巢癌(HGSOC)预后仍然较差。手术是治疗方案不可或缺的组成部分,因为去除所有可见的肿瘤病变(细胞减少)极大地改善了总体生存率。用于评估细胞减少的增强的预测工具对于优化治疗精度至关重要。患者的免疫状态大致反映了肿瘤细胞的生物学行为以及患者对疾病和治疗的反应。血清细胞因子谱是免疫适应和偏差的敏感测量,然而,它与治疗范式的整合还没有得到充分的探索。这项研究是IMPACT试验(NCT03378297)的一部分,旨在表征HGSOC初级治疗之前和期间的免疫反应,以确定治疗选择和预后的生物标志物。从诊断直到反应评估收集来自22名患者的纵向血清样品。患者接受基于腹腔镜评分的原发性细胞减灭术或新辅助化疗(NACT)。Bio-Plex200分析的27种血清细胞因子在诊断时揭示了两种免疫表型:免疫高,血清细胞因子水平明显高于免疫低。免疫表型反映了腹腔镜的评分和手术治疗的分配。接受原发性细胞减灭术的五名免疫高患者表现出免疫动员和延长的无进展生存期,与接受相同治疗的免疫低下患者相比。腹腔镜和细胞减灭术均可引起血清细胞因子的实质性和一过性变化,随着炎症细胞因子IL-6的上调和多功能细胞因子IP-10,Eotaxin的下调,IL-4和IL-7。在学习期间,所有患者的细胞因子水平均下降,导致消除初始免疫表型,无论治疗选择如何。这项研究揭示了HGSOC患者治疗前不同的免疫表型,可能为治疗分层和预后提供信息。这种潜在的新型生物标志物有望作为改善HGSOC患者治疗反应评估的基础。ClinicalTrials.gov标识符:NCT03378297。
    Despite advances in surgical and therapeutic approaches, high-grade serous ovarian carcinoma (HGSOC) prognosis remains poor. Surgery is an indispensable component of therapeutic protocols, as removal of all visible tumor lesions (cytoreduction) profoundly improves the overall survival. Enhanced predictive tools for assessing cytoreduction are essential to optimize therapeutic precision. Patients\' immune status broadly reflects the tumor cell biological behavior and the patient responses to disease and treatment. Serum cytokine profiling is a sensitive measure of immune adaption and deviation, yet its integration into treatment paradigms is underexplored. This study is part of the IMPACT trial (NCT03378297) and aimed to characterize immune responses before and during primary treatment for HGSOC to identify biomarkers for treatment selection and prognosis. Longitudinal serum samples from 22 patients were collected from diagnosis until response evaluation. Patients underwent primary cytoreductive surgery or neoadjuvant chemotherapy (NACT) based on laparoscopy scoring. Twenty-seven serum cytokines analyzed by Bio-Plex 200, revealed two immune phenotypes at diagnosis: Immune High with marked higher serum cytokine levels than Immune Low. The immune phenotypes reflected the laparoscopy scoring and allocation to surgical treatment. The five Immune High patients undergoing primary cytoreductive surgery exhibited immune mobilization and extended progression-free survival, compared to the Immune Low patients undergoing the same treatment. Both laparoscopy and cytoreductive surgery induced substantial and transient changes in serum cytokines, with upregulation of the inflammatory cytokine IL-6 and downregulation of the multifunctional cytokines IP-10, Eotaxin, IL-4, and IL-7. Over the study period, cytokine levels uniformly decreased in all patients, leading to the elimination of the initial immune phenotypes regardless of treatment choice. This study reveals distinct pre-treatment immune phenotypes in HGSOC patients that might be informative for treatment stratification and prognosis. This potential novel biomarker holds promise as a foundation for improved assessment of treatment responses in patients with HGSOC. ClinicalTrials.gov Identifier: NCT03378297.

    虽然怀孕期间使用咖啡因很常见,其与儿童行为和身体健康结果的纵向关联仍然知之甚少。这里,我们估计了产前咖啡因暴露之间的关联,体重指数(BMI),以及儿童进入青春期的行为。
    纵向数据和照顾者报告的产前咖啡因暴露来自正在进行的青少年大脑和认知发育(ABCD)SM研究,从2016年6月1日开始,该组织从美国21个地点招募了11,875名9-11岁的基线儿童。将产前咖啡因暴露作为4级分类变量进行分析,并使用进一步的组对比来表征“任何暴露”和“每日暴露”组。结果包括儿童的精神病理学特征,睡眠问题,BMI。潜在的混杂协变量包括家族性(例如,收入,家族性精神病理学),怀孕(例如,产前物质暴露),和孩子(例如,咖啡因使用)变量。
    在10,873名儿童中(5,686名男孩[52.3%];平均[SD]年龄,9.9[0.6]年),具有非缺失的产前咖啡因暴露数据,6,560(60%)在产前暴露于咖啡因。相对于没有暴露,每日咖啡因暴露与较高的儿童BMI相关(β=0.08;FDR校正p=0.02),但与儿童行为无关。那些每天暴露于两杯或更多杯咖啡因的人(n=1,028)比那些暴露于较低/不暴露的人有更大的睡眠问题(β>0.92;FDR校正p<0.04)。
    每日产前咖啡因暴露与儿童BMI升高有关,每天多次使用时,即使考虑到潜在的困惑,睡眠问题也会更严重。这种关系是否是产前咖啡因暴露或其相关因素的结果仍然未知。
    UNASSIGNED: Though caffeine use during pregnancy is common, its longitudinal associations with child behavioral and physical health outcomes remain poorly understood. Here, we estimated associations between prenatal caffeine exposure, body mass index (BMI), and behavior as children enter adolescence.
    UNASSIGNED: Longitudinal data and caregiver-reported prenatal caffeine exposure were obtained from the ongoing Adolescent Brain and Cognitive Development (ABCD) SM Study, which recruited 11,875 children aged 9-11 years at baseline from 21 sites across the United States starting June 1, 2016. Prenatal caffeine exposure was analyzed as a 4-level categorical variable, and further group contrasts were used to characterize \"any exposure\" and \"daily exposure\" groups. Outcomes included psychopathology characteristics in children, sleep problems, and BMI. Potentially confounding covariates included familial (e.g., income, familial psychopathology), pregnancy (e.g., prenatal substance exposure), and child (e.g., caffeine use) variables.
    UNASSIGNED: Among 10,873 children (5,686 boys [52.3%]; mean [SD] age, 9.9 [0.6] years) with nonmissing prenatal caffeine exposure data, 6,560 (60%) were exposed to caffeine prenatally. Relative to no exposure, daily caffeine exposure was associated with higher child BMI (β=0.08; FDR-corrected p=0.02), but was not associated with child behavior. Those exposed to two or more cups of caffeine daily (n=1,028) had greater sleep problems than those with lower/no exposure (β>0.92; FDR-corrected p<0.04).
    UNASSIGNED: Daily prenatal caffeine exposure is associated with heightened childhood BMI, and when used multiple times a day greater sleep problems even after accounting for potential confounds. Whether this relationship is a consequence of prenatal caffeine exposure or its correlated factors remains unknown.

    背景:一些研究探索了人格与工作成瘾之间的关系,这表明患有某些精神障碍的人,包括人格障碍,如强迫性人格障碍(OCPD),可能更容易工作成瘾。然而,工作狂中人格组织(PO)的特征及其对工作成瘾持续存在的贡献尚不清楚。
    方法:在这项对具有代表性的年轻人样本(N=1748)的纵向研究中,我们应用了卑尔根工作成瘾量表和人格组织量表。
    结果:我们发现工作成瘾与身份扩散之间存在显着相关性,原始的心理防御,现实测试,以及三波整体人格混乱。潜在的班级增长分析揭示了三个方面:没有工作成瘾,增加工作成瘾,和持续适度的工作成瘾。多项logistic回归分析表明,第1波中较高的人格解体水平和第1波至第3波之间的人格解体增加与加入工作成瘾组的可能性较高有关。同样,第1波较高的整体人格紊乱与属于恒定中度工作成瘾组的较高几率相关.
    结论:这些发现表明,患有慢性工作成瘾的个体的PO水平较低,随着工作成瘾的持续,PO下降。建议对工作成瘾进行筛查,以防止潜在的心理健康问题。未来的研究应探讨工作场所特征和工作动机对工作成瘾与人格障碍之间关系的影响。
    BACKGROUND: Several studies have explored the relationship between personality and work addiction, suggesting that individuals with certain mental disorders, including personality disorders such as obsessive-compulsive personality disorder (OCPD), may be more prone to work addiction. However, the characterization of personality organization (PO) among workaholics and its contribution to the persistence of work addiction remains unclear.
    METHODS: In this longitudinal study of a representative sample of young adults (N = 1748), we applied the Bergen Work Addiction Scale and the Inventory of Personality Organization.
    RESULTS: We found significant correlations between work addiction and identity diffusion, primitive psychological defenses, reality testing, and overall personality disorganization across three waves. A latent class growth analysis revealed three profiles: no work addiction, increasing work addiction, and constant moderate work addiction. Multinomial logistic regression analysis indicated that higher levels of personality disorganization in wave 1 and increases in personality disorganization between waves 1 and 3 were associated with higher odds of belonging to the increasing work addiction group. Similarly, higher overall personality disorganization in wave 1 was associated with higher odds of belonging to the constant moderate work addiction group.
    CONCLUSIONS: These findings suggest that individuals with chronic work addiction have lower levels of PO, and PO declines as work addiction persists. Screenings for work addiction are recommended to prevent potential mental health issues. Future research should explore the influence of workplace characteristics and work motivations on the association between work addiction and personality disorders.

    目的:脆弱是一种随时间变化的动态健康状态。我们的假设是,老年人群中存在可识别的亚组,这些亚组具有特定的恶化模式。这项研究的目的是评估联合潜在类别模型(JLCM)在识别老年人中虚弱进展随时间的轨迹及其特定群体的死亡风险中的应用。
    方法:英国患者的初级护理记录,截至2010年1月1日,65岁以上,包括在CPRD:GOLD和AURUM数据库中,进行了分析,并与死亡率数据相关联。电子虚弱指数(eFI)评分在基线时和随后年份(2010-2013年)每年进行计算。JLCM用于将人群划分为具有不同轨迹和相关死亡率风险比(HR)的集群。该模型在GOLD中建立,并在Aurum中进行了验证。
    结果:根据基线和前进速度确定并表征了五个轨迹簇:低速,低-中度,低快速,高慢和高快。快速集群具有最高的平均起始eFI评分;7.9,而快速集群具有最陡的eFI进展率;1.7。以低慢速集群为参考,低快速和高快速的HR最高:3.73(95CI3.71至3.76)和3.63(3.57至3.69),分别。在AURUM人群中发现了良好的验证。
    结论:我们的研究发现,老年人群中有一些脆弱的亚组,他们目前身体虚弱或有快速的虚弱进展。这样的群体可以针对更大的医疗保健监测。
    OBJECTIVE: Frailty is a dynamic health state that changes over time. Our hypothesis was that there are identifiable subgroups of the older population that have specific patterns of deterioration. The objective of this study was to evaluate the application of joint latent class model (JLCM) in identifying trajectories of frailty progression over time and their group-specific risk of death in older people.
    METHODS: The primary care records of UK patients, aged over 65 as of January 1st 2010, included in the CPRD: GOLD and AURUM databases, were analysed and linked to mortality data. Electronic frailty index (eFI) scores were calculated at baseline and annually in subsequent years (2010-2013). JLCM was used to divide the population into clusters with different trajectories and associated mortality hazard ratios (HR). The model was built in GOLD and validated in AURUM.
    RESULTS: Five trajectory clusters were identified and characterised based on baseline and speed of progression: low-slow, low-moderate, low-rapid, high-slow and high-rapid. The high-rapid cluster had the highest average starting eFI score; 7.9, while low-rapid cluster had the steepest rate of eFI progression; 1.7. Taking the low-slow cluster as reference, low-rapid and high-rapid had the highest HRs: 3.73 (95%CI 3.71 to 3.76) and 3.63 (3.57 to 3.69), respectively. Good validation was found in the AURUM population.
    CONCLUSIONS: Our research found that there are vulnerable subgroups of the older population who are currently frail or have rapid frailty progression. Such groups may be targeted for greater healthcare monitoring.

    自闭症谱系障碍是一种高度遗传性疾病,其特征是社会交往困难,经常伴随着语言的非典型性,延伸到有自闭症家族史的婴儿。这些困难背后的发育机制仍然未知。检测嘴唇运动和说话面孔的听觉语音之间的时间同步并选择性地注意嘴巴支持典型的早期语言习得。这项初步的眼动追踪研究调查了这两种基本机制在婴儿兄弟姐妹中是否具有非典型功能。我们在4、8和12个月(n=29)时,在这两种能力中,纵向跟踪了自闭症可能性高和低的婴儿的轨迹。我们展示了两个说话的面孔(同步和异步),同时记录了婴儿对说话者的眼睛和嘴巴的凝视。我们发现,婴儿在12个月时在说话的面孔中检测到时间上的异步,而与组无关。然而,与他们典型的发展中同行相比,自闭症可能性较高的婴儿在第一年结束时表现出对口腔的关注减少,并且他们对该区域的兴趣随时间没有变化。我们的发现提供了初步证据,证明了婴儿兄弟姐妹第一年在视听语音中嘴巴看起来减少的潜在非典型轨迹,对语言开发有潜在的级联后果,因此有助于对新兴自闭症的领域概述。
    Autism Spectrum Disorder is a highly heritable condition characterized by sociocommunicative difficulties, frequently entailing language atypicalities that extend to infants with a familial history of autism. The developmental mechanisms underlying these difficulties remain unknown. Detecting temporal synchrony between the lip movements and the auditory speech of a talking face and selectively attending to the mouth support typical early language acquisition. This preliminary eye-tracking study investigated whether these two fundamental mechanisms atypically function in infant siblings. We longitudinally tracked the trajectories of infants at elevated and low-likelihood for autism in these two abilities at 4, 8, and 12 months (n = 29). We presented two talking faces (synchronous and asynchronous) while recording infants\' gaze to the talker\'s eyes and mouth. We found that infants detected temporal asynchronies in talking faces at 12 months regardless of group. However, compared to their typically developing peers, infants with an elevated likelihood of autism showed reduced attention to the mouth at the end of the first year and no variations in their interest to this area across time. Our findings provide preliminary evidence on a potentially atypical trajectory of reduced mouth-looking in audiovisual speech during the first year in infant siblings, with potential cascading consequences for language development, thus contributing to domain-general accounts of emerging autism.
