Abstract
Few studies have examined how childhood experiences and characteristics shape daily prayer or meditation in adulthood across countries around the world using nationally-representative data. The current study addresses this limitation by analyzing data from the Global Flourishing Study (GFS), an international survey of 202,898 individuals from 22 geographically, economically, and culturally diverse countries collected in 2022-2023. Father-child relations, early-life religious attendance, year of birth, and gender were associated with adult daily prayer or meditation in a meta-analysis of all 22 countries. Parental marital status, economic conditions, abuse and adversity, health, and immigration status were not significant in the pooled analysis, but were important in one or more countries. All childhood characteristics showed some variation across nations. E-values suggested that the strongest associations were robust against confounding from unmeasured covariates. Cross-national research is difficult for many reasons including language barriers, norms regarding talking about sensitive issues, and survey question translation and interpretation issues. Despite these, findings show meaningful associations between numerous childhood characteristics and adult prayer or meditation around the world. Results also reveal considerable variation across countries and cultures. This work lays the foundation for future longitudinal GFS studies on the causes and correlates of prayer or meditation in a global context.

Abstract
Who shares their faith with people who have different religious views? This article examines 'faith sharing' across 22 religiously diverse countries. To our knowledge, this is the first study of 'faith sharing' across national and religious contexts. Evangelism can be controversial, but both historically and in our data, it is widespread-including in societies that restrict religious liberty. 'Faith sharing' is lowest in Europe, Japan, Australia, and the US and highest in Africa, Latin America, the Middle East, and Asia (excluding Japan). Within countries, there is no consistent pattern about which religious groups share their faith more. Previous research about 'faith sharing' focuses on Christians in the US, but the factors that predict 'faith sharing' in the US often do not generalize. In fact, the association with age, education, marital status, employment status, and immigration status is exactly the opposite in many societies. Because past comparative research ignores this topic and because so much of what we think we know about faith sharing is based on US Christians, we hope this article will spur further research and expand our understanding of religious persuasion and global religious change.

Abstract
This study analyzed data from the nationally representative Health and Retirement Study (HRS) to examine the association between widowhood and depression. The results revealed that both men and women experienced increased depression after widowhood, with women exhibiting a better recovery pattern over time. Religiosity, especially attending religious services, was found to be a beneficial coping mechanism for both genders, although men were less religious than women. Living alone was a significant factor associated with depression in widowhood for both men and women. High religious service attendance moderated the association between living alone and depression for women, while both high and moderate religious service attendance moderated this association for men. These findings emphasize the importance of considering gender differences and the potential benefits of religious involvement in addressing depression during widowhood, highlighting the need for tailored interventions and support services for widows and widowers, particularly those living alone.

Abstract
Research centered on the socioemotional benefits of religion and religious congregations for young people has highlighted largely positive outcomes for both young people and religious congregations. However, fewer studies have explored whether transgender young people receive those same socioemotional benefits from being religiously affiliated. Using secondary quantitative data from the 2015 US Transgender Survey, this study examined the religious experiences of transgender young people (aged 18-24). The data indicate that individual demographics (e.g., race, gender identity, sexual orientation, religious affiliation) affected the religious experiences of transgender young people, including leaving their congregations due to the fear of being rejected. More research is needed on the socioemotional benefits of religious affiliation for transgender young people.

Abstract
This study investigated the association between multidimensional death anxiety and religiosity in multicultural Singapore by examining potential variations by age and gender. We also explored the possibility of a curvilinear effect, where highly religious or non-religious individuals report lower death anxiety than moderately religious people, forming an inverted U-curve pattern. Data were collected from 110 participants using questionnaires that assessed death anxiety and religiosity. Parametric and non-parametric tests were then conducted. The findings showed that women had significantly higher death anxiety and religiosity than men, and highly and moderately religious people had significantly higher death anxiety than non-religious people. People of all age groups had similar levels of death anxiety. These findings highlight the importance of developing targeted death anxiety interventions that integrate spiritual aspects in Singapore so that clinicians can provide culturally competent care.

Religious status and addictive behaviors: Exploring patterns of use and psychological proneness. Compr Psychiatry 2023; 127:152418.

Abstract
BACKGROUND Previous studies have emphasized the role of religiosity as both a protective factor and a factor contributing to the success of recovery in the case of addictive beahaviors. However, the associations between religious status and the involvement in distinct addictive behaviors as well as the associations between religious status and psychological factors have not been comprehensively examined. Therefore, the aims of the present study were to extend the literature by examining the (i) relationship between religiosity and distinct addictive behaviors including substance use and behavioral addictions, and (ii) interactive effects of religious status and psychological factors on addictive behaviors. MATERIAL AND METHODS Data from two representative samples were analyzed (National Survey on Addiction Problems in Hungary [NSAPH]: N = 1385; 46.8% male; mean age = 41.77 years [SD = 13.08]; and Budapest Longitudinal Study [BLS]: N = 3890; 48.4% male; mean age = 27.06 years [SD = 4.76]). Distinct addictive behaviors and psychological factors related to the psychological proneness to addictive behaviors (impulsivity, sensation seeking, rumination, well-being, mentalization, and worry) were comprehensively examined in relation to religious status (religious, agnostic, and non-religious). Chi-square, Kruskal-Wallis and Mann-Whitney (MW) tests and multinomial logistic regressions were performed. RESULTS Religious individuals showed significantly lower involvement in addictive behaviors whereas agnostic individuals showed significantly higher involvement in addictive behaviors. With regards to psychological factors related to the proneness to addictive behaviors, agnostic individuals showed the highest level of psychological proneness. The results of multinomial regression models showed that religiosity was protective in the NSAPH sample. However, worry could overwrite the protective effect. In the BLS study, the protective role of religiosity was uncertain. It was not protective in itself, but through interaction with sensation seeking, rumination and uncertian mentalization, religiosity can also be protective. DISCUSSION The findings highlight the general protective role of religiosity in addictions. However, interaction with some psychological contructs can modify the protective role of religious status. The study also highlights the need to take into account agnostic religious status of individuals in future research. Consequently, further studies are needed to explore the causality and mediating roles between these variables.

Abstract
Introduction Age-related macular degeneration (AMD) is one of the global leading causes of severe vision loss. Patients suffering from AMD face complex spiritual and mental challenges that have an impact on the course of their disease, their quality of life, and their relationship with their surroundings. Methods A survey was carried out using a 21-item questionnaire between August 2020 and June 2021 among 117 patients from different countries to investigate how spirituality, religion, and their way of practicing them affected the experiences and daily lives of patients suffering from AMD, and whether it helped them cope with the disease. Results Our study concluded that spirituality and religion are important factors that facilitate patients' ability to cope with a progressive degenerative disease such as AMD. Patients who are religious are more at peace with having AMD. Practices that contribute to patients being at peace in accepting the disease are regular prayers or meditation. Spirituality and religion are important components that promote a healthier and happier emotional state and mental wellbeing. In particular, by believing that death is not the end, patients feel more hopeful, which helps in their adjustment to a seemingly hopeless health condition. A significant number of AMD patients desire to talk about God with the medical staff. The profile of such patients could be those believing in a higher power, praying often, participating in religious services, being worried about the loss of vision, and needing assistance in daily life. Discussion An interdisciplinary and multidimensional team of medical health professionals including mental health workers and chaplains can be of great value in managing persons with AMD.

Abstract
Religions continue to be a strong moral, even political, force in the world. They are often seen to be in conflict with women's health; we argue that this should not continue to be the case. The conflict can be traced back to when religions had their birth and early development in patriarchal communities in which women were marginalized to the edges of society. In addition, religious leadership has traditionally been dominated by men and exclusive of women. The recent introduction of new scientific technologies, which has empowered women to regulate and control their fertility, challenged traditional norms and raised a religious-inspired moral panic. However, a recent initiative has been gaining momentum. An enlightened religious leadership and a new generation of feminist religious activists are calling for a review of the original texts and a reinterpretation in a sociocultural context that is different from when they were first revealed. Obstetrician-gynecologists, while having to practice in a socioreligious context and continuing to face challenges in providing health care in religiously diverse societies, have a social responsibility to stand by women and to uphold that religions do not and should not stand in the way of advancing their health and rights.

Abstract
One of the most contentious topics in the sexual arena is that of pornography. While some researchers focus on the costs and benefits of consumption, others focus on questions surrounding the objectification or degradation of women, with relatively little focus on the men involved, and the appeal of visual sexual stimuli more generally, including what that may tell us about the sexual interests of the consumers. In this study, we focus on what factors influence men's and women's perceptions of sexually explicit images, in particular the ubiquitous external ejaculation. Sex differences in perceptions of the images are examined as well as the influence of the emotional affect of the recipient of the ejaculation, the sexual orientation of the participant (are they looking at an image of their preferred sex or not), and a number of individual difference factors, including religiosity, Dark Triad personality traits, mate value, short-term mating strategy, and disgust sensitivity. Overall, the largest influences on perceptions were the direct effects of target emotional affect and sex, sex of viewer, sexual orientation of viewer, short-term mating orientation, and level of sexual disgust. In addition, substantial variation in perceptions was explained by the interaction between sex, sexual orientation, and target sex. The importance of positive affect in the images as well as the lack of association with psychopathy again suggests that the appeal (or at least the ubiquity of the images in pornographic material) is not rooted in degradation, but in some other aspect of short-term sexual psychology.

Abstract
Background The worldwide transmission of SARS CoV-2 caused the COVID-19 pandemic and had an impact on healthcare provision. The disruption of reliance on the health system during the COVID-19 pandemic posed a clear threat to public trust. Religiosity, like spirituality, is believed to have a positive influence on people's lives, enabling them to cope with illness, stress, and sudden life changes. In practice, although the terms religiosity and spirituality have similar meanings and are related, they are not identical concepts. The aim of this study is to compare the perceptions of the accessibility and quality of healthcare services provided before and during the COVID-19 pandemic in Poland by religious/spiritual people compared to those for whom religion and spirituality have little or no importance in their lives. Methodology This cross-sectional study was based on the authors' questionnaire, carried out during the third wave of the COVID-19 pandemic in Poland. Participants in the study were people living in various regions of Poland over 18 who were willing to complete the questionnaire voluntarily. The number of people sampled was two hundred and sixty-four. Convenience sampling method was used for this study. Statistical calculations were performed using Statistica 13 software from TIBCO and PQStat from PQStat Software and were based on the Kruskal-Wallis test, multiple regression model, the chi2 test of independence or the Mann-Whitney test. The result was considered statistically significant when p < α. The significance level was taken as α = 0.05. Results Two hundred and sixty-three respondents answered the questionnaire. Among them, 181 (69%) were women, and 82 (31%) were men. It was shown that religion is more important for women than for men and women who report a high role of religion in their lives rated the quality of healthcare services better before and during the COVID-19 pandemic. It was also concluded that religious people for whom religion played a major role and those who were helped by spiritual life rated accessibility and quality higher both before and during the pandemic. Conclusions Religious/spiritual people, through their more positive attitudes towards the world, were thought to rate access and quality of healthcare services better. Regardless of religious affiliation, the help of spiritual life during the pandemic or the importance of religion in life in all respondents, perception of healthcare services utilisation were decreased by the pandemic. This prompts thoughts on the implementation of spiritual assistance as a supportive measure to mitigate the effects of the pandemic.

Abstract
Risk preference is a complex trait governed by psycho-social, environmental and genetic determinants. We aimed to examine how an individual’s risk preference associates with their epigenetic profile. Risk preferences were ascertained by asking participants of the Northern Ireland COhort for the Longitudinal study of Ageing to make a series of choices between hypothetical income scenarios. From these, four risk preference categories were derived, ranging from risk-averse to risk-seeking. Illumina’s Infinium High-Density Methylation Assay was used to evaluate the status of 862,927 CpGs. Risk preference and DNA methylation data were obtained for 1,656 individuals. The distribution of single-site DNA methylation levels between risk-averse and risk-seeking individuals was assessed whilst adjusting for age, sex and peripheral white cell counts. In this discovery cohort, 55 CpGs were identified with significantly different levels of methylation (p≤x10−5) between risk-averse and risk-seeking individuals when adjusting for the maximum number of covariates. No CpGs were significantly differentially methylated in any of the risk preference groups at an epigenome-wide association level (p<9x10−8) following covariate adjustment. Protein-coding genes NWD1 and LRP1 were among the genes in which the top-ranked dmCpGs were located for all analyses conducted. Mutations in these genes have previously been linked to neurological conditions. Epigenetic modifications have not previously been linked to risk-aversion using a population cohort, but may represent important biomarkers of accumulated, complex determinants of this trait. Several striking results from this study support further analysis of DNA methylation as an important link between measurable biomarkers and health behaviours.
