Breastfeeding and offspring’s compassion and empathy in adulthood: A study with an over 30-year follow-up

This study investigated whether breastfeeding predicts offspring’s dispositional compassion and empathy from early adulthood to middle age. The parents of the participants (N = 1,394) of the Young Finns study answered questions about breastfeeding in 1983, and the participants’ compassion and empathy were evaluated in 1997‒2012 (participants were aged 20‒50 years). Breastfeeding did not predict the course of compassion or empathy in adulthood at the age of 20‒50 years. The associations remained non-significant, when adjusted for age, gender, socioeconomic factors, and a wide range of characteristics of the family environment (including mother’s gestational age; premature birth; birth weight; number of other children at home; parental mental disorder; parental relationship status; parental postnatal smoking; parental postnatal alcohol use; parenting behavior; and child’s externalizing behavior). In conclusion, breastfeeding seems not to predict offspring’s compassion or empathy in adulthood. The findings may present a hopeful perspective for children growing up with non-breastfeeding caregivers.     

Is Symptomatic Long QT Syndrome Associated with Depression in Women and Men?

We examined whether long QT syndrome (LQTS) mutation carrier status or symptomatic LQTS are associated with depression, and whether there are sex differences in these potential relationships. The sample comprised 782 participants (252 men). Of the 369 genetically defined LQTS mutation carriers, 169 were symptomatic and 200 were asymptomatic. The control group consisted of 413 unaffected relatives. Depression was assessed using the Beck Depression Inventory-II (BDI-II). No association was found for LQTS mutation carrier status with depression. The multinomial logistic regression showed that LQTS mutation carrier men with arrhythmic events scored higher on depression compared with the control group, even when adjusting for age, β-blockers, antidepressants, and social support (OR = 1.09, 95 % CI [1.02, 1.15], p = .007). The binary logistic regression comparing symptomatic and asymptomatic LQTS mutation carriers showed that symptomatic LQTS was associated with depression in men (OR = 1.10, 95 % CI [1.03, 1.19], p = .009). The results were unchanged when additionally adjusted for education. These findings suggest that symptomatic LQTS is associated with depression in men but not in women. Overall, however, depression is more frequent in women than men. Thus, regular screening for depression in LQTS mutation carriers and their unaffected family members can be important.     

Interactive effect of long-term mental stress and cardiac stress reactivity on carotid intima-media thickness: the Cardiovascular Risk in Young Finns study

The present study examined the interaction between vital exhaustion and cardiac reactivity and recovery on preclinical atherosclerosis assessed by carotid intima-media thickness (IMT) in young men and women. We measured heart rate (HR), respiratory sinus arrhythmia (RSA), and pre-ejection period (PEP) in response to mental arithmetic and speech tasks. Vital exhaustion and carotid IMT were also measured. Significant associations were observed for men aged 28-37 years, but not for men aged 22-25 years, nor for women in these age groups. It was shown that, among highly exhausted men in the older age group, lower HR reactivity was related to greater IMT. Our results also imply that, among non-exhausted men in this age group, slow HR and RSA recovery after acute stress predicted higher IMT. These results suggest that long-term stress as assessed by vital exhaustion is a risk only if it has resulted in ineffective cardiac stress reactivity. Autonomic imbalance resulting from chronic stress may be the common mechanism linking vital exhaustion and cardiac responsiveness to an increased risk of atherosclerosis.     

Intergenerational Continuity in Qualities of the Parent–Child Relationship: Mediating and Moderating Mechanisms

Intergenerational continuity in parenting quality has been demonstrated but the mechanisms underlying this continuity are less understood. This study investigated whether the offspring personality and years of education mediate the continuity in qualities of the parent–child relationship and whether offspring personality moderates this association. The sample comprised 1308 Finnish offspring (G2; 62% female) and their mothers (G1). G1 (Mean age?=?37.7) reported self-perceived qualities of the parent–child relationship in terms of emotional warmth and acceptance towards G2 aged 3–18 years in 1980. Thirty-two years later, once having become parents themselves, G2 (Mean age?=?42.9) self-rated their own qualities of the parent–child relationship towards their children using the same scales. Between these follow-ups, G2 self-rated their personality (consisting of temperament and character traits) using the Temperament and Character Inventory and reported years of education. Results indicated that G2 character traits—Self-directedness and Cooperativeness—partially mediated the intergenerational continuity in self-perceived emotional warmth and explained 16% of this association. No mediating role of G2 temperament traits was found (all ps?>?.240). Character traits accounted for the indirect association better than education in a multiple mediator model. Moreover, no moderating role of either temperament or character traits was found (all ps?≥?.064). Study findings show that warm and accepting qualities of the parent–child relationship in childhood are related to offspring character traits that reflect personality maturity in adulthood, which in turn would predict their own positive parent–child relationship later in life.     

Associations of Youth and Adulthood Body-Mass Index and Waist-Hip Ratio with Attachment Styles and Dimensions

The current cross-sectional study examined whether body-mass index (BMI) and waist-hip ratio are associated with adult attachment. Participants were 1,570 men and women participating in Cardiovascular Risk in Young Finns study. BMI was measured in youth and in adulthood and waist-hip ratio in adulthood. A single measure of attachment style was conducted when participants were aged 24–39 years. In age and sex adjusted models, youth BMI (Beta = .066, p = .008), adulthood BMI (Beta = .069, p = .007) and waist-hip ratio (Beta = .082, p = .016) were associated with fearful attachment. The associations remained significant when education and relationship status were adjusted for. Age adjusted association between adulthood waist-hip ratio and preoccupied attachment was found in men (Beta = .132, p = .002). The association was not essentially changed by additionally adjusting for education and relationship status, and including fearful attachment in the model. Furthermore, associations for attachment dimensions were also found. These results suggest that in addition to previously reported negative effects of higher BMI on physical health, higher BMI might have negative associations with psychological functioning as well. Furthermore, our results imply that physical appearance might be associated with attachment style in adulthood.     

Personality traits and perceptions of organisational justice

This study examined the association between five‐factor model personality traits and perceptions of organisational justice. The sample for the study comprised 903 participants (35–50 years old; 523 women) studied in 2007 and 2012. Measures used were the Neuroticism, Extraversion, Openness, Five‐Factor Inventory questionnaire and the short organisational justice measure. The results showed that high neuroticism was associated with low distributive, procedural and interactional justice. Furthermore, high agreeableness was associated with high procedural and interactional justice and high openness with high distributive justice. This study suggests that neuroticism, agreeableness and openness are involved in perceptions of organisational justice and that personality should be considered in research and in practices at the workplace.

Adult temperament and childbearing over the life course

Emerging evidence suggests that temperament may predict childbearing. We examined the association between four temperament traits (novelty seeking, harm avoidance, reward dependence and persistence of the Temperament and Character Inventory) and childbearing over the life course in the population‐based Cardiovascular Risk in Young Finns study (n = 1535; 985 women, 550 men). Temperament was assessed when the participants were aged 20–35 and fertility history from adolescence to adulthood was reported by the participants at age 30–45. Discrete‐time survival analysis modelling indicated that high childbearing probability was predicted by low novelty seeking (standardized OR = 0.92; 95% confidence interval 0.88–0.97), low harm avoidance (OR = 0.90; 0.85–0.95), high reward dependence (OR = 1.09; 1.03–1.15) and low persistence (OR = 0.91; 0.87–0.96) with no sex differences or quadratic effects. These associations grew stronger with increase in numbers of children. The findings were substantially the same in a completely prospective analysis. Adjusting for education did not influence the associations. Despite its negative association with overall childbearing, high novelty seeking increased the probability of having children in participants who were not living with a partner (OR = 1.29; 1.12–1.49). These data provide novel evidence for the role of temperament in influencing childbearing, and suggest possible weak natural selection of temperament traits in contemporary humans.

Gender differences in teachers’ perceptions of students’ temperament,educational competence,and teachability

Background. Student's temperament plays a significant role in teacher's perception of the student's learning style, educational competence (EC), and teachability. Hence, temperament contributes to student's academic achievement and teacher's subjective ratings of school grades. However, little is known about the effect of gender and teacher's age on this association. Aims. We examined the effect of teacher's and student's gender and teacher's age on teacher‐perceived temperament, EC, and teachability, and whether there is significant same gender or different gender association between teachers and students in this relationship. Sample. The participants were population‐based sample of 3,212 Finnish adolescents (M= 15.1 years) and 221 subject teachers. Methods. Temperament was assessed with Temperament Assessment Battery for Children – Revised and Revised Dimensions of Temperament Survey batteries and EC with three subscales covering Cognitive ability, Motivation, and Maturity. Data were analyzed with multi‐level modelling. Results. Teachers perceived boys’ temperament and EC more negatively than girls’. However, the differences between boys and girls were not as large when perceived by male teachers, as they were when perceived by female teachers. Males perceived boys more positively and more capable in EC and teachability than females. They were also stricter regarding their perceptions of girls’ traits. With increasing age, males perceived boys’ inhibition as higher and mood lower. Generally, the older the teacher, the more mature he/she perceived the student. Conclusions. Teachers’ ratings varied systematically by their gender and age, and by students’ gender. This bias may have an effect on school grades and needs be taken into consideration in teacher education.     

Dimensions of social support in the experience of work engagement in middle age: A Northern Finland Birth Cohort 1966 Study

So far, the relationship between the various dimensions of social support and work engagement has not been widely examined in the literature. In this study, we examined the relationship of social support at work (from a colleague or supervisor) and social support in one’s private life (from a spouse, relative or friend) with various dimensions of work engagement (vigor, dedication and absorption). The participants (N = 5,259–5,376, 46 years-old, 52.7% women) came from the Northern Finland Birth Cohort 1966 study. Social support was evaluated with the Social Support Questionnaire (SSQ), and work engagement was assessed with a short version of the Utrecht Work Engagement Scale (UWES-9). The data were analyzed using linear regression analyses. The results showed that high social support at work (p < 0.001) and in one’s private life (p < 0.001) were associated with higher total work engagement, higher vigor, higher dedication, and higher absorption. These findings were adjusted for gender, marital status, education and occupational status. The results were essentially unchanged when they were additionally adjusted for job strain and effort-reward imbalance. To conclude, our findings indicate that the experience of overall social support may play a role in the experience of work engagement.
