“…It is thought that even if unmarried people live with their families, the perceived loneliness level is higher than married people, and this, in previous studies, affects the vagal regulation of perceived loneliness. [28]…”

Heart rate variability (HRV) is a noninvasive assessment that reflects the autonomic functions of the heart and is known to be impaired in many diseases. In our study, we aimed to investigate the relationship between HRV and being married. The study included 104 patients, between the aged 20 to 40 years were included in the study. The patients were divided into 2 groups as 53 healthy married (group 1) and 51 healthy unmarried (group 2). 24-hour rhythm Holter recordings were performed on all married and unmarried patients. Group 1 had a mean age of 32 ± 5 years and 47.2% men, and group 2 had a mean age of 30 ± 5 years and 54.9% men. Standard deviation of normal to normal (SDNN) was 150 ± 40 versus 128 ± 30 (P = .003), SDNN index was 66 ± 20 versus 56 ± 12 (P = .004), the square root of the mean of the squares of the differences of the adjacent root mean square of successive differences (RMSSD) was 37 ± 10 versus 30 ± 10 (P < .001), percentage of successive R-R intervals that differ by more than 50 milliseconds (PNN50) was 13.5 ± 7 versus 8.5 ± 7 (P = .001), HF was 450 ± 270 versus 225 ± 130 (P < .001) found to be significantly less in the group 2. LF/HF ratio was 1.68 ± 0.65 versus 3.31 ± 1.56 (P < .001) found to be significantly higher in the group 2. In our study, it is possible to say that the sympathetic system effect on the heart was more dominant and the HRV was lower in the unmarried group.

Loneliness is prevalent during emerging adulthood (approximately 18–25 years) and is an important issue given it has been linked to poorer physical and mental health outcomes. This preregistered scoping review aimed to provide an overview of the literature on loneliness in emerging adulthood, including the (a) conceptualization and measurement of loneliness, (b) loneliness theories used, (c) risk factors and outcomes examined, (d) sex-gender differences observed, and (e) characteristics of emerging adult samples previously researched. Following the Joanna Briggs Institute (JBI) guidelines, seven electronic databases were searched for articles focused on loneliness published from 2016 to 2021, where the mean age of participants was ≥ 18 and ≤ 25 years. Of the 4068 papers screened, 201 articles were included in the final review. Findings suggest the need for a clearer consensus in the literature regarding the conceptualization of loneliness for emerging adults and more qualitative work exploring emerging adults’ subjective experiences of loneliness. Results highlight an over-reliance on cross-sectional studies. Over two thirds of articles described their sample as university students and the median percentage of females was 63.30%. Therefore, fewer cross-sectional studies using convenience samples and more population-based, longitudinal research is needed to understand the factors predicting loneliness over time, and the downstream impact of loneliness for emerging adults.

Chronic loneliness and low perceived social support have been recognized as risk factors for both mental and cardiovascular disorders. It has been proposed that their link to psychophysiological problems may involve changes in parasympathetic activity. However, the exact underlying psychopathological mechanisms and the moderating effects of gender are still not thoroughly examined. Thus, the present study investigated associations between perceived social functioning and resting vagal tone in the context of potential cognitive and subclinical mediators and gender differences. Three hundred twenty‐five young adults (aged 18–35, 180 women) underwent an electrocardiogram measurement of 6‐minute resting heart rate variability (HRV). They also completed questionnaires assessing loneliness, perceived social support, social cognitive biases, depressive and social anxiety symptoms, and general mental health. In men, HRV was significantly and negatively associated with poorer perceived social functioning, depressive symptoms, and self‐reported social cognitive biases, while in women, there was a quadratic link between HRV and depressive symptoms and HRV and general mental health. Moderated mediation analysis revealed that depressive symptoms fully mediated the relationship between perceived social functioning and HRV in men. The results suggest that decreased resting vagal tone in lonely individuals is linked to depressive symptomatology rather than to specific social cognitive biases and that this association is significant only in men.
