Is there intergenerational continuity in early life experiences? Findings from the Harvard Study of Adult Development.

There has been longstanding and widespread interdisciplinary interest in understanding intergenerational processes, or the extent to which conditions repeat themselves across generations. However, due to the difficulty of collecting longitudinal, multigenerational data on early life conditions, less is known about the extent to which offspring experience the same early life conditions that their parents experienced in their own early lives. Using data from a socioeconomically diverse, White U.S. American cohort of 1,312 offspring (50% female) and their fathers (N = 518 families), we address three primary questions: (1) To what extent is there intergenerational continuity in early life experiences (social class, home atmosphere, parent-child relationship quality, health)? (2) Is intergenerational continuity in early life experiences greater for some domains of experience compared to others? and (3) Are there person-level (offspring sex, birth order, perceptions of marital stability) and family-level factors (family size, father education level and education mobility, marital stability) that moderate intergenerational continuity? Multilevel models indicated that intergenerational continuity was particularly robust for childhood social class, but nonsignificant for other early life experiences. Further, intergenerational continuity was moderated by several family-level factors, such that families with higher father education/mobility and marital stability, tended to have offspring with the most optimal early life experiences, regardless of what their father experienced in early life. We discuss the broader theoretical implications for family systems, as well as practical implications for individual-level and family-level interventions.

Diagnostic yield of asymptomatic arrhythmias detected by mobile cardiac outpatient telemetry and autotrigger looping event cardiac monitors.

INTRODUCTION: Asymptomatic arrhythmias can have important therapeutic implications in certain patient populations, for example, atrial fibrillation in patients with prior ischemic stroke. We sought to compare the diagnostic yield of two commercially available monitoring systems with automated arrhythmia detection algorithms. METHODS: We queried a large, proprietary database containing rhythm data for patients receiving ambulatory EKG monitoring (BioTelemetry, Malvern, PA, USA). We compared all patients prescribed mobile cardiac outpatient telemetry (MCOT™, Braemar Manufacturing, LLC, Eagan, MN, USA) versus autotrigger looping event recorder (AT-LER) devices over a consecutive 8-month period. Data from both device types were analyzed for diagnostic yields in detecting asymptomatic (device-triggered) arrhythmias consisting of atrial fibrillation (of any detected duration), bradycardia (ventricular rate ≤ 40 bpm), ventricular pause (≥ 3 seconds), supraventricular tachycardia (≥ 6 consecutive supraventricular beats), and ventricular tachycardia (≥ 4 consecutive premature ventricular contractions). The mean time to first diagnosis of each arrhythmia for each device was determined. Physician-designated diagnostic codes for patients prescribed each device were also determined from the database. RESULTS: The MCOT™ device had significantly higher diagnostic yields of all evaluated asymptomatic arrhythmias than the AT-LER. The MCOT™ device also produced an earlier mean time to diagnosis for all evaluated asymptomatic arrhythmias. These findings were noted despite a shorter average prescription length for MCOT™ monitored patients. CONCLUSIONS: In patients with conventional diagnostic monitoring indications, MCOT™ had significantly higher diagnostic yields for five asymptomatic arrhythmias compared to the AT-LER.
