The aim of this study was to translate the Attitudes and Beliefs about Cardiovascular Disease (ABCD) Risk Questionnaire into Norwegian and assess its psychometric properties among individuals with a history of myocardial infarction.

The study adopted a cross-sectional design. The original questionnaire was translated into Norwegian and adapted for use in the target population. The Norwegian version was pilot tested in a sample of patients and then validated in the target population.

A random sample of Norwegian individuals

Internal consistency was tested using Cronbach’s α and test–retest reliability using intraclass correlation coefficient (ICC). Difficulty and discrimination indices were determined for the Knowledge scale. Confirmatory factor analysis (CFA) was used to assess structural validity of the Risk scale.

Data for 746 participants (mean age, SD: 66.4, 10.3 years), of which 26.9% females were analysed. The Norwegian version showed satisfactory internal consistency (Cronbach’s α 0.73–0.79) but modest test–retest reliability (ICC 0.35–0.64). The Knowledge scale showed moderate difficulty (0.39–0.84) and good discrimination power (0.44–0.60). The one-factor model CFA for each scale achieved acceptable fit, and the four-factor model showed moderate fit (root mean square error of approximation=0.05, standardised root mean squared residual=0.07, Comparative Fit Index=0.91, Tucker-Lewis Index=0.88).

The Norwegian translated ABCD Risk Questionnaire demonstrated satisfactory psychometric properties and can be considered a useful instrument for assessing knowledge and risk perception among individuals with a history of myocardial infarction.

To describe the normal heart rate (HR) of healthy newborns ≥35+0 weeks’ gestation in the first 10 min after caesarean delivery (CD) with extrauterine placental transfusion, using dry-electrode ECG (NeoBeat).

Single-centre, prospective observational study.

Norwegian County Hospital.

Newborns ≥35+0 weeks’ gestation delivered by CD under regional anaesthesia were eligible for inclusion. Newborns delivered by CD under general anaesthesia, or who needed medical intervention, were excluded.

NeoBeat was attached to the newborn’s chest immediately following delivery. The placenta was delivered without cord clamping after 60–90 s and transferred with the newborn to a resuscitation table. Modified physiology-based cord clamping (PBCC) was performed.

HR was recorded every second for 10 min. HR quartiles were calculated. Events possibly influencing HR were annotated using Liveborn Observation App.

89 newborns with a mean (SD) gestational age of 39+3 weeks (10 days) and birth weight of 3649 (536) g were included. Median (IQR) HR was 164 (117–176) and 169 (145–186) beats per minute at 20 s and 30 s, respectively, peaking at 169 (152–183) beats per minute at 4 min and then slowly decreasing to 157 (146–167) beats per minute at 10 min. HR was not significantly affected by intact-cord blood sampling (mean difference=5.4 (95% CI –1.4 to 12.1)), placental delivery (mean difference=0.7 (95% CI –3.5 to 4.9)) or cord clamping (mean difference =–0.6 (95% CI –2.1 to 0.9)).

This report describes, for the first time, HR quartiles for healthy newborns ≥35⁰ weeks’ gestation from 15 s to 20 s and up to 10 min after CD with extrauterine placental transfusion and PBCC.
