Marital Satisfaction in Postpartum Women: The Role of Personality, Body Image Satisfaction, Anxiety, and Sexual Function

Background:

The postpartum period is considered a vulnerable and stressful period for many women due to various hormonal, physical, and psychosocial changes, such as adapting to parental rules, changes in body and self-image, loss of autonomy, breastfeeding, and taking care of the baby

Objective:

This study aimed to test a conceptual model considering the interrelated role of anxiety, body image satisfaction, sexual function, type of personality, income, and education on women’s marital satisfaction. Also it also aimed to test the mediating role of sexual function and anxiety.

Methods:

In this cross-sectional study, 447 lactating women were recruited from January to April 2019. Women answered some questionnaires including a socio-demographic checklist, female sexual function index (FSFI), Body Self-Relation Questionnaire (BSRQ), the Enrich Marital Satisfaction, and the NEO Personality Inventory (NEO PI-R). Data were analyzed using the descriptive test, and Path analysis was done with LISREL software.

Results:

Results show that sexual function (β= 0.44), anxiety (β= -0.26), and educational level (β= 0.47) are the main predictors of marital satisfaction (dependent variable). Sexual function and anxiety were two main mediators; variables, such as anxiety (β= -0.35), body image satisfaction (β= 0.19), and extraversion personality (β= 0.19) (independent variables), with an effect through sexual function, can impress marital satisfaction indirectly.

Conclusion:

Identifying relationships between anxiety, educational level, sexual function, anxiety, body image, and personality with the quality of life of postpartum women highlights the importance of designing interventions to improve marital satisfaction. Given these relationships, it is recommended that health professionals educate women about body changes during postpartum and find ways to improve mothers' marital satisfaction.

The prospective power of personality for childbearing: a longitudinal study based on data from Germany

The link between personality and fertility is relatively underexplored. Moreover, there are only a few studies focusing on the prospective association between personality and childbearing. However, none of these studies considered the Five-Factor Model (FFM), which is the most widely accepted measurement of personality. The present study fills this gap by examining the prospective association between the FFM and the hazard ratio of the first and the second childbirth in Germany. Analyses are based on recent data (2005–2017) from the Socio-economic Panel Study. Cox proportional hazard models are applied. Findings demonstrate that personality traits are associated with fertility. Extraversion is positively linked with the first childbirth, but is negatively associated with the second childbirth. These findings are mainly driven by males. Agreeableness is positively linked with the first childbirth across the total sample. Again, this correlation is mainly based on the findings for men, among whom a positive association between agreeableness and the second childbirth is also found. Among women, personality does not seem to be linked with the first childbirth. However, the risk of having a second child is found to be negatively associated with conscientiousness. My study adds to the current understanding of the personality–fertility association by exploring the impact of personality trait scores from the FFM on subsequent fertility behavior. However, further research is needed on the association between personality and childbearing; on the mechanisms through which personality affects fertility; and on how these links differ across cultures, among higher parities, and for births after re-partnering.

Reduced reproductive success is associated with selective constraint on human genes

Genome-wide sequencing of human populations has revealed substantial variation among genes in the intensity of purifying selection acting on damaging genetic variants¹. Although genes under the strongest selective constraint are highly enriched for associations with Mendelian disorders, most of these genes are not associated with disease and therefore the nature of the selection acting on them is not known². Here we show that genetic variants that damage these genes are associated with markedly reduced reproductive success, primarily owing to increased childlessness, with a stronger effect in males than in females. We present evidence that increased childlessness is probably mediated by genetically associated cognitive and behavioural traits, which may mean that male carriers are less likely to find reproductive partners. This reduction in reproductive success may account for 20% of purifying selection against heterozygous variants that ablate protein-coding genes. Although this genetic association may only account for a very minor fraction of the overall likelihood of being childless (less than 1%), especially when compared to more influential sociodemographic factors, it may influence how genes evolve over time.

Extraversion development in childhood, adolescence and adulthood: Testing the role of sport participation in three nationally-representative samples

This research sought to test whether sport participation relates to the development of trait extraversion across three life phases. Sport participation and extraversion were measured in children aged 10.5 ± 0.5 years (n = 3600), in adolescents aged 14.5 ± 0.5 years (n = 3463), and in adults with a mean age of 49.4 ± 18.0 years (n = 12,280), with corresponding data collected four years earlier. There were small mean-level decreases in extraversion during childhood and adulthood, and a large decrease in extraversion during adolescence. Four-year rank-order stability in extraversion was .58 in childhood, .61 in adolescence and .76 in adulthood. Sport participation was associated with higher extraversion in all three samples. After controlling for sociodemographic factors, children and adolescents who dropped out of sport showed greater decreases in extraversion than those who continued participation in sport. Sport participation was unrelated to mean-level change in extraversion during adulthood. Sport participation was also associated with greater intra-individual stability in extraversion for children, adolescents and adults. There were no significant sex moderation effects for mean-level change or individual-level stability. These findings provide evidence that sport participation might have an important role in trait extraversion stability and change across the lifespan.
