We aimed to depict the trajectories of the neighborhood social exposome from middle to late adolescence and assess the intricate relationship between them and late adolescent mental health. METHODS: Participants (n = 3965) from the FinnTwin12 cohort with completed questionnaires at age 17were used...

INTRODUCTION: Children and adolescents with elevated internalizing symptoms are at increased risk for depression, anxiety, and other psychopathology later in life. The present study examined the predictive links between two bioecological factors in early childhood-parental hostility and socioeconomic stress-and children's internalizing symptom class outcomes, while considering the effects of child sex assigned at birth on internalizing symptom development from childhood to adolescence...

INTRODUCTION: Health-related quality of life (HRQoL) should be considered when evaluating the burden of road trauma (RT) injuries. This study aimed to identify distinct HRQoL trajectories following minor to severe RT injury and determine characteristics of trajectory membership. METHODS: This prospective inception cohort study recruited 1480 RT survivors from three emergency departments in British Columbia, Canada (July 2018 - March 2020). HRQoL outcome was measured with the Short Form 12 survey (SF-12) and the 5-level version of the EuroQol instrument (EQ-5D-5L) at baseline (pre-injury) and at 2, 4, 6, and 12 months post-injury...

AIMS: To determine if distinct trajectories of coronary heart disease (CHD) self-care behaviours could be identified, linked to differences in quality of life (QoL), and predicted based on baseline characteristics. METHODS AND RESULTS: A secondary analysis of a prospective, longitudinal, observational study. Patients with CHD answered questionnaires at study enrolment and six months later: Self-Care of Coronary Heart Disease Inventory (three subscales: maintenance, management and confidence, scored 0-100, higher score = better self-care), Hospital Anxiety and Depression Scale, 12-Item Short Form Survey, 16-Item European Health Literacy Survey Questionnaire, CHD Education Questionnaire...

An ever-growing body of empirical evidence has demonstrated the relationship between depression and cancer. The objective of this study was to examine whether depression trajectories predict mortality risk above and beyond demographics and other general health-related factors. Participants (n = 2,345) were a part of the Health and Retirement Study. The sample consisted of patients who were assessed once before their cancer diagnosis and thrice after. Depressive symptoms and general health-related factors were based on self-reports...

BACKGROUND: Previous studies of non-small cell lung cancer (NSCLC) focused on CEA measured at a single time point, ignoring serial CEA measurements. METHODS: This retrospective cohort included 2959 patients underwent surgery for stage I-III NSCLC. CEA trajectory patterns and long-term cumulative CEA burden were evaluated using the latent class growth mixture model. RESULTS: Four CEA trajectory groups were identified, named as low-stable, decreasing, early-rising and later-rising...

The aims of this study were to (a) identify the trajectory of symptom clusters in patients with inflammatory bowel disease up to 28 weeks after initiation of infliximab therapy and (b) examine the illness perceptions associated with symptom cluster trajectories. This was a prospective study where participants completed the symptom cluster scale at baseline, 14 weeks, and 28 weeks. A latent growth mixture modeling was used to identify trajectories of symptom clusters that were predicted, using baseline covariates (Brief Illness Perception Questionnaire)...

BACKGROUND: Previous research has largely lacked studies that explore the trajectories of Posttraumatic stress symptoms (PTSS) and the structure of comorbid psychiatric symptom networks following traumatic event, while controlling for the severity of traumatic exposure. The present study aims to explore the characteristic trajectories of PTSS, in the context of ensuring controlled levels of traumatic exposure. Furthermore, the PTSS, depressive, and anxiety comorbid symptom networks of different PTSS trajectory subgroups are also investigated...

Trajectories refer to the motion paths followed by objects in space. Disease trajectories, which depict the evolution of disease processes over time, are significantly important for assessing diseases, formulating treatment strategies, and predicting prognosis. Critical illness is one of the leading causes of death. With advances in critical care medicine, there is increasing focus on the occurrence and development of critical illnesses. Understanding the development trajectory of critical illness is helpful to promote the early identification, intervention, and treatment of high-risk patients, avoid prolongation of the course of disease, reduce the risk of multiple organ failure, and provide important reference for the development of targeted prevention and intervention strategies, thereby reducing the incidence and mortality of critical illness...

We aimed to identify parents' dental anxiety trajectories and the association of the trajectories with the number of parents' and their children's oral healthcare procedures in the FinnBrain Birth Cohort Study. Dental anxiety was measured with the Modified Dental Anxiety Scale at gestational weeks (gw) 14 and 34, as well as 3 and 24 months (mo) after childbirth. Oral healthcare procedures from gw14 to 24 mo were obtained from the national patient data register and categorized as preventive and treatment. Trajectories were identified with latent growth mixture modelling for 2068 fathers and 3201 mothers...

Applying latent growth mixture modeling (GMM), this study delves into the examination of self-esteem trajectories in a sample of 5,597 older adults over a nine-year period. Four distinct patterns of self-esteem changes have emerged: low, decreasing, increasing, and high. Additionally, the study explores the relationships between each trajectory and various predictors encompassing demographic factors, socioeconomic status, health, and interpersonal relationships. The findings highlight the significance of these factors in predicting the likelihood of an individual following a specific self-esteem trajectory...

The relationship between online self-disclosure and self-concept clarity has been previously examined through cross-sectional studies. This study examined causal connections between online self-disclosure and self-concept clarity among Chinese middle school students using longitudinal data collected over 18 months. Participants were 535 seventh-grade students aged 12-14 years (Mage = 12.93, SD = 0.54, 43.18% girls), assessed four times, six months apart. In a random intercept cross-lagged panel model, self-concept clarity significantly predicted online self-disclosure...

BACKGROUND: Analyzing trajectories of weight loss may address how particular groups of patients respond to metabolic and bariatric surgery. OBJECTIVES: The Bariatric Experience Long Term (BELONG) study was designed to use a theoretical model to examine determinants of weight loss and recurrence. SETTING: Large integrated health system in Southern California with 11 surgical practices and 23 surgeons. METHODS: A total of n = 1338 patients who had metabolic and bariatric surgery were surveyed before surgery to measure factors related to median percent total weight loss (%TWL) over 5 years...

OBJECTIVE: Treatment outcome monitoring typically emphasizes pathology. In contrast, we responded to the need to establish psychodynamic psychotherapy as evidence-based by modeling changes in gratitude and forgiveness. METHOD: We utilized a practice-based research design involving non-manualized outpatient treatment. We employed a longitudinal mixture modeling approach to evaluate treatment effectiveness. We did so by testing the theorized role for relational virtues (i...

OBJECTIVE: Little is known about the normative courses of pregnancy-related anxiety throughout pregnancy and their antecedents. We examined in a large scale pregnancy cohort which potentially distinct trajectories of pregnancy-related anxiety across pregnancy can be identified, and which factors predict these trajectories. METHODS: A general sample of pregnant women (n = 2928) from the FinnBrain Birth Cohort participated in this study. Several questionnaires were filled in at 14, 24, and 34 weeks of gestation, including the pregnancy-related anxiety questionnaire-revised as main outcome...

School enjoyment, as a measure of how much adolescents enjoy or value their school experience, has been extensively studied in Western cultures. However, our knowledge of school enjoyment, and particularly its changes and trajectories among adolescents living in non-Western cultures, is limited. The present study used 3-year longitudinal data to examine changes and trajectories in school enjoyment and their associations with social and relational factors, such as mental health problems and peer victimization, among Japanese middle school students...

A growing number of studies have examined alcohol use during the COVID-19 pandemic. However, few longitudinal studies evaluated the prevalence and correlates of different trajectories of problematic alcohol use in vulnerable segments of the population, such as US veterans, over the 3-year course of the COVID-19 pandemic. Data were analyzed from the National Health and Resilience in Veterans Study, a nationally representative, longitudinal study of 2,441 US veterans. Latent growth mixture modeling was used to identify the trajectories and correlates of problematic alcohol use...

BACKGROUND: Understanding the association of acute pain intensity and opioid consumption after cardiac surgery with chronic postsurgical pain (CPSP) can facilitate implementation of personalized prevention measures to improve outcomes. The objectives were to (1) examine acute pain intensity and daily mg morphine equivalent dose (MME/day) trajectories after cardiac surgery, (2) identify factors associated with pain intensity and opioid consumption trajectories, and (3) assess whether pain intensity and opioid consumption trajectories are risk factors for CPSP...

INTRODUCTION: China is one of the countries with the highest burden of hypertensive intracerebral haemorrhage (HICH), and its morbidity and mortality rates are almost twice the world average. Most survivors experience negative emotions such as anxiety and depression due to symptoms such as speech disorders, dysphagia, cognitive impairment, hemiplegia and ataxia. While evidence has emerged, supporting the acceptance of disability is a major factor in psychosocial adjustment of patients with disabilities...

Nutrition is one of the important factors that play a major role in the growth and development of children so that they can develop optimally. Child malnutrition, such as stunting, underweight, and wasting, is a significant problem in Indonesia. The World Health Organization (WHO) determined that the nutritional status of children under five in Indonesia is in the chronic category, one of which is in Southeast Sulawesi Province. This study examines and analyzes the factors that influence the nutritional status of children under five in Southeast Sulawesi using the Partial Least Square Structural Equation Modeling (SEM-PLS) method and then segments the nutritional status of children under five using Response Based Unit Segmentation Modeling in Partial Least Square (REBUS-PLS) and Finite Mixture Partial Least Square (FIMIX-PLS)...
