Parental Post-traumatic Stress and Healthcare Use in Infants with Complex Cardiac Defects.

OBJECTIVE: To examine the associations between post-traumatic stress of parents of infants with complex congenital heart defects and their healthcare use for their infants during the early months of life. STUDY DESIGN: The current study is a secondary data analysis from a randomized controlled trial in which 216 parent-infant dyads were recruited from 3 cardiac intensive care units of large pediatric centers in Northeastern America. The current sample included 153 dyads with post-traumatic stress data at hospital discharge and at 4-months' follow-up. Poisson regressions were used to estimate the effect of post-traumatic stress change scores on number of emergency department (ED) visits, unscheduled cardiologist visits, and unscheduled pediatrician visits outcomes. RESULTS: Infants whose parents gained post-traumatic stress disorder over the study period were at increased risk for ED visits and unscheduled cardiologist visits. Increased symptom severity predicted more unscheduled cardiologist visits and more unscheduled pediatrician visits. Increased symptom clusters (avoidance, arousal, re-experiencing) predicted more ED visits, more unscheduled cardiologist visits, and more unscheduled pediatrician visits. CONCLUSIONS: Parents of infants with cardiac conditions may experience post-traumatic stress following cardiac surgery, which can be linked to greater healthcare use. Findings highlight the importance of screening and treating post-traumatic stress to preserve parental mental health and prevent adverse outcomes.

Midday napping in children: associations between nap frequency and duration across cognitive, positive psychological well-being, behavioral, and metabolic health outcomes.

STUDY OBJECTIVES: Poor sleep and daytime sleepiness in children and adolescents have short- and long-term consequences on various aspects of health. Midday napping may be a useful strategy to reduce such negative impacts. The effect of habitual napping on a wide spectrum of cognitive, behavioral, psychological, and metabolic outcomes has not been systematically investigated. METHODS: This study characterized midday napping habits in 3819 elementary school children from the China Jintan Cohort Study. In 2011, weekly nap frequency and average duration were collected once from students at grades 4-6. Prior to their completion of elementary school at grade 6 (in 2011-2013 respective to each grade), the following outcomes were collected once: behavioral and academic achievement evaluated by teachers, and self-reported positive psychology measures including grit, self-control, and happiness. IQ tests were conducted on a subgroup. Metabolic indices, including body mass index and fasting glucose concentration, were measured through physical exams. For the whole sample, we assessed associations between napping and each outcome, adjusted for sex, grade, school location, parental education, and time in bed at night. We also conducted stratified analyses on grade 6 (cross-sectional), grade 4 (2-year gap), and grade 5 (1-year gap) data. RESULTS: Overall, napping was significantly associated with higher happiness, grit, and self-control, reduced internalizing behavior problem, higher verbal IQs, and better academic achievement, although specific patterns varied across frequency and duration for different outcomes. More limited significant associations were found for decreased externalizing behavior problems, compared to non-nappers, while no significant associations were found for performance IQ and metabolic outcomes. CONCLUSIONS: Results indicate benefits of regular napping across a wide range of adolescent outcomes, including better cognition, better psychological wellness, and reduced emotional/behavioral problems. The current study underscores the need for further large-scale intervention studies to establish causal effects.
