A new large-scale study of European adults suggests that, on average, being religiously educated as a child is associated with slightly poorer self-rated health after the age of 50. The research, published in the journal Social Science & Medicine, also indicates that this association is not uniform, varying significantly across different aspects of health and among different segments of the population.
Past research has produced a complex and sometimes contradictory picture regarding the connections between religiousness and health. Some studies indicate that religious involvement can offer health benefits, such as reduced suicide risk and fewer unhealthy behaviors. Other research points to negative associations, linking religious attendance with increased depression in some populations.
Most of this work has focused on religious practices in adulthood, leaving the long-term health associations of childhood religious experiences less understood. To address this gap, researchers set out to investigate how a religious upbringing might be linked to health outcomes decades later, taking into account the diverse life experiences that can shape a person’s well-being.
The researchers proposed several potential pathways through which a religious upbringing could influence long-term health. These include psychosocial mechanisms, where religion might foster positive emotions and coping strategies but could also lead to internal conflict or distress. Social and economic mechanisms might involve access to supportive communities and resources, while also potentially exposing individuals to group tensions.
Finally, behavioral mechanisms suggest religion may encourage healthier lifestyles, such as avoiding smoking or excessive drinking, which could have lasting positive effects on physical health. Given these varied and sometimes opposing potential influences, the researchers hypothesized that the link between a religious upbringing and late-life health would not be simple or consistent for everyone.
To explore these questions, the study utilized data from the Survey of Health, Aging, and Retirement in Europe, a major cross-national project. The analysis included information from 10,346 adults aged 50 or older from ten European countries. Participants were asked a straightforward question about their childhood: “Were you religiously educated by your parents?” Their current health was assessed through self-ratings on a five-point scale from “poor” to “excellent.” The study also examined more specific health indicators, including physical health (chronic diseases and limitations in daily activities), mental health (symptoms of depression), and cognitive health (numeracy and orientation skills).
The researchers employed an advanced statistical method known as a causal forest approach. This machine learning technique is particularly well-suited for identifying complex and non-linear patterns in large datasets. Unlike traditional methods that often look for straightforward, linear relationships, the causal forest model can uncover how the association between a religious upbringing and health might change based on a wide array of other factors. The analysis accounted for 19 different variables, including early-life circumstances, late-life demographics like age and marital status, and current religious involvement.
The overall results indicated that, on average, having a religious upbringing was associated with poorer self-rated health in later life. The average effect was modest, representing a -0.10 point difference on the five-point health scale. The analysis showed that for a majority of individuals in the sample, the association was negative.
However, the model also identified a smaller portion of individuals for whom the association was positive, suggesting that for some, a religious upbringing was linked to better health outcomes. This variation highlights that an average finding does not tell the whole story.
When the researchers examined different domains of health, a more nuanced picture emerged. A religious upbringing was associated with poorer mental health, specifically a higher level of depressive symptoms. It was also linked to poorer cognitive health, as measured by lower numeracy, or mathematical ability.
In contrast, the same childhood experience was associated with better physical health, indicated by fewer limitations in activities of daily living, which include basic self-care tasks like bathing and dressing. This suggests that a religious childhood may have different, and even opposing, associations with the physical, mental, and cognitive aspects of a person’s well-being in later life.
The study provided further evidence that the link between a religious upbringing and poorer self-rated health was not the same for all people. The negative association appeared to be stronger for certain subgroups. For example, individuals who grew up with adverse family circumstances, such as a parent with mental health problems or a parent who drank heavily, showed a stronger negative link between their religious education and later health.
Late-life demographic factors also seemed to modify the association. The negative link was more pronounced among older individuals (aged 65 and above), females, those who were not married or partnered, and those with lower levels of education. These findings suggest that disadvantages or vulnerabilities experienced later in life may interact with early experiences to shape health outcomes.
The analysis also considered how adult religious practices related to the findings. The negative association between a religious upbringing and later health was stronger for individuals who reported praying in adulthood. It was also stronger for those who reported that they never attended a religious organization as an adult. This combination suggests a complex interplay between past experiences and present behaviors.
The study does have some limitations. The data on religious upbringing and other childhood circumstances were based on participants’ retrospective self-reports, which can be subject to memory biases. The study’s design is cross-sectional, meaning it captures a snapshot in time and cannot establish a direct causal link between a religious upbringing and health outcomes. It is possible that other unmeasured factors, such as parental socioeconomic status, could play a role in this relationship. The measure of religious upbringing was also broad and did not capture the intensity, type, or strictness of the education received.
Future research could build on these findings by using longitudinal data to track individuals over time, providing a clearer view of how early experiences unfold into later life health. More detailed measures of religious education could also help explain why the experience appears beneficial for some health domains but detrimental for others. Researchers also suggest that exploring the mechanisms, such as coping strategies or social support, would provide a more complete understanding.
