Abstract
The experience of human parenthood is near ubiquitous and can profoundly alter one's body, mind, and environment. However, we know very little about the long-term neural effects of parenthood for parents themselves, or the implications of pregnancy and caregiving experience on the aging adult brain. Here, we investigate the link between the number of children parented and age on brain function in 19,964 females and 17,607 males from the UK Biobank. In both females and males, parenthood was positively correlated with functional connectivity, such that higher number of children parented was associated with higher connectivity, particularly within the somato/motor network. Critically, the spatial topography of parenthood-linked effects was inversely correlated with the impact of age on functional connectivity across the brain for both females and males, such that the connections that were positively correlated with number of children were negatively correlated with age. This result suggests that a higher number of children is associated with patterns of brain function in the opposite direction to age-related alterations. Overall, these results indicate that the changes accompanying parenthood may confer benefits to brain health across the lifespan, altering aging trajectories, consistent with animal models of parenthood and preliminary findings of "younger-looking" brain structure in human parents. Observing this effect in both females and males implicates the caregiving environment, rather than pregnancy alone, and highlights the importance of future work to disentangle the underlying mechanisms related to the direct impact of caregiving, the indirect impact of the environment, and the result of covarying sociodemographic factors.

Abstract
PURPOSE Although there are different instruments that evaluate self-care, most of them have not been validated for use in the Spanish population or in the general adult population. Moreover, there is little evidence on its relationship with psychological and family adjustment. Therefore, the aims of this study were to: (1) validate the self-care scale for adults and (2) analyse its external validity, verifying its relationship with general psychological and family adjustment variables. METHODS The sample was constituted by 971 parents (56.5% women) with children in early childhood (0-5 years) aged 23-58 years (M = 38.11). Exploratory and confirmatory factor analyses, correlations and Student's t mean contrasts were carried out. RESULTS Good fit indices for the scale, which presented a bifactor structure composed of physical and psychological self-care. Both types of self-care were directly related to life satisfaction and positive affect; on the other hand, they were negatively related to parental stress, the presence of family-work conflict, and the guilt related to such conflict. The mothers reflected lower levels of psychological self-care. CONCLUSIONS The developed questionnaire is a valid instrument that can be useful in the measurement of self-care in adults and particularly in parents of young children. It is highlighted the need to design initiatives that improve parental well-being through the study construct.

JMIR Form Res 2025; 9:e65658.

Abstract
BACKGROUND Psychologists have developed frameworks to understand many constructs, which have subsequently informed the design of digital mental health interventions (DMHIs) aimed at improving mental health outcomes. The science of happiness is one such domain that holds significant applied importance due to its links to well-being and evidence that happiness can be cultivated through interventions. However, as with many constructs, the unique ways in which individuals experience happiness present major challenges for designing personalized DMHIs. OBJECTIVE This paper aims to (1) present an analysis of how sex may interact with age, marital status, and parental status to predict individual differences in sources of happiness, and (2) to present a preliminary discussion of how open datasets may contribute to the process of designing health-related technology innovations. METHODS The HappyDB is an open database of 100,535 statements of what people consider to have made them happy, with some people asking to consider the past 24 hours (49,831 statements) and some considering the last 3 months (50,704 statements). Demographic information is also provided. Binary logistic regression analyses are used to determine whether various groups differed in their likelihood of selecting or not selecting a category as a source of their happiness. RESULTS Sex and age interacted to influence what was selected as sources of happiness, with patterns being less consistent among female individuals in comparison with male individuals. For marital status, differences in sources of happiness were predominantly between married individuals and those who are divorced or separated, but these were the same for both sexes. Married, single, and widowed individuals were all largely similar in their likelihood of selecting each of the categories as a source of their happiness. However, there were some anomalies, and sex appeared to be important in these anomalies. Sex and parental status also interacted to influence what was selected as sources of happiness. CONCLUSIONS Sex interacts with age, marital status, and parental status in the likelihood of reporting affection, bonding, leisure, achievement, or enjoying the moment as sources of happiness. The contribution of an open dataset to understanding individual differences in sources of happiness is discussed in terms of its potential role in addressing the challenges of designing DMHIs that are ethical, responsible, evidence based, acceptable, engaging, inclusive, and effective for users. The discussion considers how the content design of DMHIs in general may benefit from exploring new methods informed by diverse data sources. It is proposed that examining the extent to which insights from nondigital settings can inform requirements gathering for DMHIs is warranted.

Abstract
Unplanned births remain relatively common, even in regions with high contraceptive prevalence and accessible abortion services, such as contemporary France. Previous studies have shown that unplanned births can have numerous negative consequences for the well-being of mothers and children, including poorer maternal health behaviors, delayed and insufficient prenatal care, and depression during or immediately after pregnancy. However, these studies do not provide conclusive evidence on whether the observed outcomes are a consequence of unplanned births or of the conditions in which they likely occur. Furthermore, scant attention has been given to other dimensions of maternal well-being, such as physical health. This study uses longitudinal data from the French Constances Cohort and applies fixed-effects event study models to examine how women's self-rated general health and risk of depressive symptoms are affected in the years following an unplanned birth. Results show that women who had an unplanned birth reported a sudden, significant drop in their general health in the year following the birth, particularly among the youngest, while health outcomes following planned births showed a gradual, slight decrease over the time-period considered. The risk of depressive symptoms increased similarly after birth for both unplanned and planned births. This study contributes to the literature by using a longitudinally constructed measure of unplanned births based on pre-birth fertility intentions, rather than commonly used retrospective measures prone to ex post rationalization. It also distinguishes between unwanted and mistimed births while further examining their consequences on medium-term maternal health.

Abstract
Working life is associated with lifestyle, screening uptake, and occupational health risks that may explain differences in cancer onset. To better understand the association between working life and cancer risk, we need to account for the entire employment history. We investigated whether lifetime employment trajectories are associated with cancer risk. We used data from 6809 women and 5716 men, average age 70 years, from the Survey of Health, Ageing, and Retirement in Europe. Employment history from age 16 to 65 was collected retrospectively using a life calendar and trajectories were constructed using sequence analysis. Associations between employment trajectories and self-reported cancer were assessed using logistic regression. We identified eight employment trajectories for women and two for men. Among women, the risk of cancer was higher in the trajectories "Mainly full-time to home/family", "Full-time or home/family to part-time", "Mainly full-time", and "Other" compared with the "Mainly home/family" trajectory. Among men, the risk of cancer was lower in the "Mainly self-employment" trajectory compared with "Mainly full-time". We could show how employment trajectories were associated with cancer risk, underlining the potential of sequence analysis for life course epidemiology. More research is needed to understand these associations and determine if causal relationships exist.

Abstract
Although a large body of research has documented the negative effects of insecure employment for adult workers, less is known about the consequences for their children's well-being. Our understanding of the mechanisms through which insecure maternal employment may affect children is particularly limited. This study examines the relationship between insecure maternal employment and child behaviour difficulties from the age of 4-16 using seven waves of data for nearly 5000 families from Growing Up in Australia: The Longitudinal Study of Australian Children. Employing fixed effects models to account for unobserved time-invariant heterogeneity, we found that children whose mothers were casual contract employees or economically inactive had greater behaviour difficulties, on average, than their peers whose mothers were permanent employees. Maternal mental health and parenting, rather than household financial strain, contributed to explaining the association between insecure maternal employment and child behaviour difficulties. These results were more pronounced for younger children (up to the age of 12). This study contributes to the literature on the consequences of maternal employment insecurity for child mental health in high-income countries by clarifying the mechanisms behind this association.

In both females and males, increased parity was positively associated with functional connectivity, particularly within the somato/motor network. Critically, the spatial topography of parity-linked effects was inversely correlated with the impact of age on functional connectivity across the brain for both females and males, suggesting that a higher number of children is associated with patterns of brain function in the opposite direction to age-related alterations.

Abstract
This study examines the stability of child attachment to mothers and fathers separately, and to both parents as a network between the infancy and preschool periods using a sample of 143 biparental families and their children (73 boys) recruited from the general population. Attachment was assessed at 15 months with the Strange Situation Procedure (SSP) and at 45 months with the Preschool Attachment Classification Coding System (PACS). First, results show no stability in attachment to mothers, to fathers, or to both parents as a network. Second, parents' mental health, life satisfaction, marital satisfaction, and child externalizing behavior are associated with attachment stability. Taken altogether, group comparisons reveal that children with a stable secure attachment to both parents as a network have parents with higher levels of well-being and exhibit less problem behaviors than children with 1) a stable secure attachment to one parent and an unstable attachment to the other parent (from secure to insecure or from insecure to secure), or 2) who never had a stable secure attachment to either parent. This study highlights the significance of attachment to both parents as a network over time as it is associated with developmental outcomes.
