A Big Five approach to self-regulation: personality traits and health trajectories in the Hawaii longitudinal study of personality and health.

Self-regulatory processes influencing health outcomes may have their origins in childhood personality traits. The Big Five approach to personality was used here to investigate the associations between childhood traits, trait-related regulatory processes and changes in health across middle age. Participants (N = 1176) were members of the Hawaii longitudinal study of personality and health.

Comparative Effectiveness of Statin Therapy in Chronic Kidney Disease and Acute Myocardial Infarction: A Retrospective Cohort Study.

Background: Whether there is a kidney function threshold to statin effectiveness in patients with acute myocardial infarction is poorly understood. Our study sought to help fill this gap in clinical knowledge.

Methods: We undertook a new-user cohort study of the effectiveness of statin therapy by level of estimated glomerular filtration rate (eGFR) in adults who were hospitalized for myocardial infarction between 2000 and 2008.

Personal health record use for children and health care utilization: propensity score-matched cohort analysis.

Objectives: To examine the association between caregiver personal health record (PHR) use and health care utilization by pediatric patients.

Design, Setting, And Participants: We conducted a retrospective observational cohort study of 2286 pediatric members aged six months to 2.5 years of Kaiser Permanente Hawaii and Northwest Regions in 2007-2011, using propensity score matching methods and t and chi-square tests to examine associations between PHR use and health care utilization.

A life-span behavioral mechanism relating childhood conscientiousness to adult clinical health.

Objective: To investigate a life-span health-behavior mechanism relating childhood personality to adult clinical health.

Methods: Childhood Big Five personality traits at mean age 10, adult Big Five personality traits, adult clinically assessed dysregulation at mean age 51 (a summary of dysregulated blood glucose, blood pressure, and lipids), and a retrospective, cumulative measure of life-span health-damaging behavior (lifetime smoking, physical inactivity, and body mass index from age 20) were assessed in the Hawaii Personality and Health Cohort (N = 759). Structural equation modeling was used to test the conceptual model with direct and indirect paths from a childhood Conscientiousness factor to an adult Conscientiousness factor, life-span health-damaging behaviors, educational attainment, adult cognitive ability, and adult clinical health.

Hepatitis B virus infection testing and prevalence among Asian and Pacific Islanders.

Objectives: Asian and Pacific Islanders (APIs) constitute less than 6% of the US population, but account for more than half of Americans with chronic hepatitis B virus (HBV) infection. We sought to examine the effect of country of origin on HBV testing and chronic HBV infection prevalence among APIs.

Methods: We analyzed demographic and clinical data collected for adults from Kaiser Permanente Hawaii with 1 or more healthcare encounters during 2006 to 2008, 12 months or more of follow-up before 2009, and no HBV-related diagnosis within 6 months of enrollment.

Longitudinal associations between sex, diabetes self-care, and health-related quality of life among youth with type 1 or type 2 diabetes mellitus.

Objective: To examine the longitudinal associations between sex, diabetes self-care, and the health-related quality of life (HRQL) of children and adolescents with type 1 or type 2 diabetes.

Study Design: The sample included 910 participants with type 1 and 241 participants with type 2, ages 10-22 years at baseline, from the SEARCH for Diabetes in Youth Study, a longitudinal observational study. The primary outcome measure was the Pediatric Quality of Life Inventory.

Prevalence of and disparities in barriers to care experienced by youth with type 1 diabetes.

Objective: To describe the prevalence of access and process barriers to health care and to examine their relationship to sociodemographic and disease factors in a large and diverse cohort of US youth with type 1 diabetes.

Study Design: A cross-sectional analysis of 780 youth who participated in the SEARCH for Diabetes in Youth Study and were diagnosed with type 1 diabetes in 2002-2005. Experience of barriers to care was collected from parent report on questionnaires.

Personal health record use and association with immunizations and well-child care visits recommendations.

Objective: To determine the association of parental use of integrated personal health records (PHRs) with children's adherence to immunization and well-child care (WCC) visit recommendations.

Study Design: For the immunization and WCC visit measures, we retrospectively analyzed, respectively, 766 and 639 matched pairs at Kaiser Permanente (KP) Hawaii and 2795 and 2448 pairs at KP Northwest who were ≤ 31 days old at enrollment and continuously enrolled for 2 years between January 2007 and July 2011. The independent variable (≥ 1 PHR feature used vs none) was matched using propensity scores on parental and children characteristics.
