How the first years of motherhood impact the cardiac autonomic profile of female healthcare professionals: a study by heart rate variability analysis.
<p>Dataset from Dalla Vecchia LA, De Maria B, Cassetti G, Clementi L, De Grazia V, Perego F, Porta A. How the first years of motherhood impact the cardiac autonomic profile of female healthcare professionals: a study by heart rate variability analysis. Sci Rep. 2021 Apr 14;11(1):8161. doi: 10.1038/s41598-021-87596-y. PMID: 33854133; PMCID: PMC8047021.</p> <p>Abstract</p> <p>The conciliation between career and family is a relevant issue for working women, in particular during the first years of motherhood. Data about the state of the cardiac autonomic regulation in working women with preschoolers are lacking. Aim of this study was to compare the cardiac autonomic profile of female healthcare professionals with and without preschoolers via the analysis of the variability of the time distance between two consecutive R-wave peaks (RR) from standard 24-h Holter electrocardiogram (ECG). Fifty healthy active female healthcare professionals were enrolled: 25 with at least one preschooler (W_KID) and 25 without (W_NOKID). A standard Holter ECG was obtained during a regular working day. Segments of 5000 consecutive RRs were selected during daytime (DAY) and nighttime (NIGHT). Heart rate variability analysis was performed and the following parameters were considered for comparison between the two groups: mean (μ<sub>RR</sub>), variance (σ<sup>2</sup><sub>RR</sub>), and the absolute power in high frequency component (HF) of RR (HF<sub>RR</sub>) series. HF<sub>RR</sub> was considered as a marker of vagal cardiac modulation. Only µ<sub>RR</sub> significantly increased from DAY to NIGHT in both groups (699 ± 88 vs 887 ± 140 ms in W_KID and 728 ± 90 vs 942 ± 166 ms in W_NOKID). Instead, σ<sup>2</sup><sub>RR</sub> and HF<sub>RR</sub> increased from DAY to NIGHT only in W_NOKID (from 3334 ± 2153 to 4816 ± 4063 ms<sup>2</sup> and from 356 ± 334 to 1397 ± 1629 ms<sup>2</sup>, respectively). W_KID showed lower σ<sup>2</sup><sub>RR</sub> and HF<sub>RR</sub> during NIGHT, compared to W_NOKID (2336 ± 3170 vs 4816 ± 4063 ms<sup>2</sup> and 556 ± 950 vs 1397 ± 1629 ms<sup>2</sup>, respectively). The perceived stress according to the visual analogue scale was similar in the two groups (4.7 ± 2.1 in W_KID, 5.7 ± 2.1 in W_NOKID). The presence of preschoolers lowered nocturnal cardiac vagal modulation in female healthcare professionals. This might represent an adaptation with a finalistic purpose, scilicet the facilitation of a prompt reaction in case of a child's need.</p>
Autonomic cardiac profile in male and female healthcare professionals with and without preschoolers: differences evidenced by heart rate variability analysis
<p>De Maria B, Cassetti G, Clementi L, De Grazia V, Parati M, Perego F, Porta A, Dalla Vecchia LA. Autonomic cardiac profile in male and female healthcare professionals with and without preschoolers: differences evidenced by heart rate variability analysis. Sci Rep. 2022 Aug 25;12(1):14499. doi: 10.1038/s41598-022-18744-1. PMID: 36008506; PMCID: PMC9411539.</p> <p>Abstract</p> <p>A reduced nocturnal cardiac vagal modulation has been observed in working women with preschoolers. Whether this adaptation also occurs in men remains an open question. The aim of this study was to analyze the cardiac autonomic profile of two groups of healthcare male professionals, one with and one without preschoolers, to be compared to females. Twenty-five working men with preschoolers (M_KID, age 35.41 ± 4.01 years) and 25 without (M_NOKID, 34.48 ± 6.00 years) were compared with 25 working women with preschoolers (W_KID, 37.7 ± 5.6 years) and 25 without (W_NOKID, 35.4 ± 7.2 years). A 24-h Holter electrocardiogram was performed for time and frequency domain analysis of the beat-to-beat variations of RR interval (RR) variability, during daytime (DAY) and nighttime (NIGHT). The power of RR variability in the high frequency band (HF<sub>RR</sub>) was considered as an index of cardiac vagal modulation. RR variability indices were similar in M_KID and M_NOKID during both DAY and NIGHT. In contrast, W_KID showed a reduced nocturnal HF<sub>RR</sub> compared to W_NOKID. The comparison of working men with and without preschoolers revealed no differences in the cardiac autonomic profile, in contrast with women. This suggests that sex and/or gender may represent a crucial factor in the cardiac neural control in the parental condition.</p>
