Impact of parental cancer on IQ, stress resilience, and physical fitness in young men

Joint exposure to parental cancer and income loss during childhood and the child's socioeconomic position in early adulthood: a Danish and Norwegian register-based cohort study

BACKGROUND

Parental cancer as well as economic hardship in the family during childhood can affect the child negatively. Our aim was to examine the association between the joint exposure to parental cancer and income loss in childhood and the child's socioeconomic position in early adulthood.

METHODS

We conducted a register-based prospective cohort study of children born in Denmark between 1978 and 1986 and in Norway between 1979 and 1987. The children were followed from 1 January 1994 (in Denmark) or 1995 (in Norway). Educational level and personal income were measured at age 30 years. Children who experienced parental cancer between the years they turned 8 and 16 years were identified, and exposure to income loss was measured in the same period. Adjusted multinomial logistic regression model was used to estimate relative risk ratios for the joint exposure of parental cancer and income loss during childhood.

RESULTS

Children who experienced parental cancer and an income loss during childhood had an increased risk of low education and lower income at age 30 years. The associations were weaker for children only exposed to income loss and less clear for those only exposed to parental cancer. Further, exposure to parental cancer with a severe cancer type was associated with lower educational level.

CONCLUSION

The child's educational attainment and income level in early adulthood were negatively affected by exposure to income loss in childhood, and even more so if exposed to both parental cancer and income loss. The associations with educational attainment were stronger for more severe cancer types.

Child- and family-specific communication skills trainings for healthcare professionals caring for families with parental cancer: A systematic review

Introduction

As part of high-quality cancer care, healthcare professionals (HCPs) play a significant role in identifying and addressing specific needs of cancer patients parenting minor children. However, HCPs experience various barriers to adequately support parents with cancer. This systematic review explores current CSTs incorporating child- and family- specific modules for HCPs in oncology. Moreover, outcome measures and effectiveness of trainings are systematically investigated.

Methods

The systematic review was registered within PROSPERO (registration code: CRD42020139783). Systematic searches were performed in four databases (PubMed, Cinahl, PsycInfo, Web of Science) in 12/2020, including an update in 12/2021 and 08/2022. Quantitative, primary studies fulfilling the pre-defined inclusion criteria were included. Due to the expected heterogeneity a meta-analysis was not conducted. Study selection and quality assessment were conducted by two independent researchers, data extraction by one. Study quality was assessed using an adapted version of the National Institutes of Health quality assessment tool for pre-post studies without control group.

Results

Nine studies were included in this review following an experimental pre-post design only. Two CSTs were specifically designed to improve communication with cancer patients parenting minor children, the remaining seven incorporated a brief family module only. Seven programs were face-to-face trainings, one an e-learning and one a webinar. Eight studies found at least one statistically significant improvement in communication after training. However, quality of most studies was fair.

Conclusion

This is the first review exploring specific CSTs for HCPs caring for cancer patients parenting minor children. As only two CSTs focused on parental cancer, evidence on the effectiveness of such CSTs is limited. Existing CSTs should be evaluated properly and include details on content of family modules. Further studies including and evaluating specific CSTs focusing on parental cancer are needed in order to strengthen HCPs’ competencies to meet specific needs of patients parenting minor children.

Effects of parental health shocks on children's school achievements: A register-based population study

This paper studies how a severe parental health shock affects children's school achievements using a rich longitudinal dataset of Danish children. We use coarsened exact matching to control for potential endogeneity between parental health and children's school outcomes and employ cancer specific survival rates to measure the size of the health shock. We find robust negative (albeit small) effects of a parental health shock on children's basic school grades as well as their likelihood of starting and finishing secondary education, especially for poor prognosis cancers. We observe different outcomes across children's gender and age and gender of the ill parent, but no effects of family-related resilience factors such as parental education level. The effects appear to be driven by non-pecuniary costs rather than by pecuniary costs. Moreover, we find that the negative effects on school performance increase in the size of the health shock for both survivors and non-survivors.

Remote and adjacent psychological predictors of early-adulthood resilience: Role of early-life trauma, extraversion, life-events, depression, and social-support

Resilience is important for people to maintain mental health after negative life-events. However, its longitudinal psychological and social predictors are poorly revealed. Based on the ecological system theory model, the current study aimed to determine the longitudinal temporal mechanism underlying the development of early-adulthood resilience using long-term (early-life trauma and personality), medium-term and short-term (life-events, social support, and depression) psychosocial predictors. A total of 505 university students were recruited at baseline (T1), 433 of whom took part in a three-year longitudinal investigation (T2). The results showed that at T1 and T2, the resilience scores of individuals were identically high (72.98 and 73.21, respectively). Pearson correlation analysis showed that early-adulthood resilience was negatively correlated with early-life trauma, psychoticism and neuroticism, depression, ad life-events, and positively correlated with extraversion, social-support, and resilience. Regression and structural equation models showed that extraversion had a direct positive effect on T1 resilience through the mediation of T1 life-events, depression, and social-support, while childhood emotional neglect (EN) had indirect negative effect and extraversion had direct positive effect on T2 resilience through the mediation of T1 resilience, and T2 depression and social-support. In conclusion, this study is among the first to reveal the longitudinal temporal process of the development of early-adulthood resilience using remote and adjacent psychosocial predictors. The findings confirm that childhood EN and extraversion have a remote impact on early-adulthood resilience through recent and current depression and social-support. Our results imply that early-life trauma does not hinder the development of early-adulthood resilience in a linear trend.

Death of a parent during childhood and blood pressure in youth: a population-based cohort study of Swedish men

OBJECTIVE

Compelling evidence suggests that childhood adversities are associated with an increased risk of hypertension in middle age and old age. The link between childhood adversities and blood pressure in youth is less clear. In this cohort study, we examined the association between death of a parent during childhood and blood pressure in early adulthood in men.

SETTING

Sweden.

PARTICIPANTS

We studied 48 624 men born in 1949-1951 who participated in the compulsory military conscription in 1969/1970 in Sweden. Information on death of a parent during childhood was obtained from population-based registers. Information on covariates was obtained from the questionnaire and the clinical examination completed at conscription and from population-based registers.

OUTCOME MEASURES

Blood pressure was measured at conscription according to standard procedures.

RESULTS

The multivariable least square means of systolic and diastolic blood pressure did not differ between bereaved (128.25 (127.04-129.46) and 73.86 (72.89-74.84) mm Hg) and non-bereaved study participants (128.02 (126.86-129.18) and 73.99 (73.06-74.93) mm Hg). Results were similar when considering the cause of the parent's death, the gender of the deceased parent or the child's age at loss. Loss of a parent in childhood tended to be associated with an increased hypertension risk (OR and 95% CI: 1.10 (1 to 1.20)); the association was present only in case of natural deaths.

CONCLUSION

We found no strong support for the hypothesis that stress following the loss of a parent during childhood is associated with blood pressure or hypertension in youth in men.

Heart rate, intelligence in adolescence, and Parkinson's disease later in life

To investigate whether physical and cognitive fitness measured in late adolescence was associated with future risk of Parkinson’s disease (PD). The cohort included 1,259,485 Swedish men with physical fitness, body mass index (BMI), resting heart rate (RHR), blood pressure, intelligence quotient (IQ), and stress resilience measured at the age of 17–20 in relation to conscription. Incident cases of PD were ascertained from the Swedish Patient Register. Hazard ratios were estimated from Cox models, after controlling for multiple confounders. We further performed Mendelian randomization (MR) analyses to assess the causality of the associations, using GWAS summary statistics with > 800,000 individuals. During follow-up, we identified 1,034 cases of PD (mean age at diagnosis = 53). Men with an RHR > 100 beats per minute had a higher risk of PD compared to men with an RHR of 60–100 beats per minute (HR = 1.47; 95% CI = 1.08–1.99). Men with IQ above the highest tertile had a higher risk of PD compared to men with an IQ below the lowest tertile (HR = 1.46; 95% CI = 1.19–1.79). We found no association for physical fitness, BMI, blood pressure, or stress resilience. A causal relationship was suggested by the MR analysis between IQ and PD, but not between RHR and PD. RHR and IQ in late adolescence were associated with a higher risk of PD diagnosed at relatively young age. The association of IQ with PD is likely causal, whereas the association of RHR with PD suggests that altered cardiac autonomic function might start before 20 years of age in PD.

Estimates of Prevalence Rates of Cancer Patients With Children and Well-Being in Affected Children: A Systematic Review on Population-Based Findings

This review assessed population-based estimate rates of cancer patients with minor and young adult children (≤ 25 years), children and young adults having a parent with cancer as well as the psychosocial situation and well-being of children and young adults affected by parental cancer. Eighteen publications on population-based studies were included. Studies varied in the age ranges of both cancer patients and children. The prevalence rates of cancer patients having children ranged from 14 to 24.7% depending on the sample structure (e.g., age, gender). Studies reported that between 1.6 and 8.4% of children resp. young adult children have a parent with a history of cancer. Seven publications reported on the psychosocial situation or well-being in children and young adults affected by parental cancer. Estimate rates of psychosocial problems, psychiatric diagnoses or distress ranged between 2.5 and 34% of children depending on the method of measurement and outcome. The differences in the sample structure between the studies impeded the comparison of prevalence rates. However, the findings help to determine the need for specific support services and health care planning. The results emphazise the importance to routinely include issues on the parental role of patients and questions on the well-being and coping of children into psychooncological care. If necessary, support should be provided to families living with a cancer diagnosis.

Association Between Physical Fitness and Anxiety in Children: A Moderated Mediation Model of Agility and Resilience

Background: Anxiety is one of the most prevalent mental health problems in children. Although physical fitness as a predictor of mental health, the mechanisms underlying any association between physical fitness and anxiety in children have been understudied. Thus, the aim of the present study was to determine whether an association exists between physical fitness and anxiety and to explore the roles of agility and resilience in such an association.

Methods: This cross-sectional study investigated 269 children aged 7 to 12 years from three public primary schools in Shanghai (China). Physical fitness and agility were objectively measured, and resilience and anxiety were assessed using self-reported questionnaires. The moderated mediation model was examined using the SPSS PROCESS macro, in which the moderator variable was agility, and the mediator variable was resilience.

Results: Physical fitness was inversely associated with anxiety. Resilience partially and indirectly mediated this association, and agility moderated the association between physical fitness and resilience. Physical fitness had a greater impact on resilience in children with higher agility levels.

Conclusions: Agility moderated the mediation of resilience on the indirect, inverse association between physical fitness and anxiety; thus, incorporating methods to develop agility and resilience may lead to better outcomes for physical fitness programs designed to prevent or alleviate anxiety in children.

Shared unmeasured characteristics among siblings confound the association of Apgar score with stress resilience in adolescence

Aim

We investigated the association between low Apgar score, other perinatal characteristics and low stress resilience in adolescence. A within‐siblings analysis was used to tackle unmeasured shared familial confounding.

Methods

We used a national cohort of 527 763 males born in Sweden between 1973 and 1992 who undertook military conscription assessments at mean age of 18 years (17–20). Conscription examinations included a measure of stress resilience. Information on Apgar score and other perinatal characteristics was obtained through linkage with the Medical Birth Register. Analyses were conducted using ordinary least squares and fixed‐effects linear regression models adjusted for potential confounding factors.

Results

Infants with a prolonged low Apgar score at five minutes had an increased risk of low stress resilience in adolescence compared with those with highest scores at one minute, with an adjusted coefficient and 95% confidence interval of −0.26 (−0.39, −0.13). The associations were no longer statistically significant when using within‐siblings models. However, the associations with stress resilience and birthweight remained statistically significant in all analyses.

Conclusion

The association with low Apgar score seems to be explained by confounding due to shared childhood circumstances among siblings from the same family, while low birthweight is independently associated with low stress resilience.
