Cross-cousin marriage among Tsimane forager-horticulturalists during demographic transition and market integration.

Although still prevalent in many human societies, the practice of cousin marriage has precipitously declined in populations undergoing rapid demographic and socioeconomic change. However, it is still unclear whether changes in the structure of the marriage pool or changes in the fitness-relevant consequences of cousin marriage more strongly influence the frequency of cousin marriage. Here, we use genealogical data collected by the Tsimane Health and Life History Project to show that there is a small but measurable decline in the frequency of first cross-cousin marriage since the mid-twentieth century. Such changes are linked to concomitant changes in the pool of potential spouses in recent decades. We find only very modest differences in fitness-relevant demographic measures between first cousin and non-cousin marriages. These differences have been diminishing as the Tsimane have become more market integrated. The factors that influence preferences for cousin marriage appear to be less prevalent now than in the past, but cultural inertia might slow the pace of change in marriage norms. Overall, our findings suggest that cultural changes in marriage practices reflect underlying societal changes that shape the pool of potential spouses.

Marriage and childbearing in patients with epilepsy in Turkey.

Introduction: For epilepsy, a common neurological disorder, brings psychosocial challenges like stigma, employment difficulties, and barriers to marriage and childbearing. Stigma often stems from misconceptions and societal beliefs, particularly in less developed regions like Turkey. However, research on the marital and childbearing experiences of epilepsy patients in such settings is limited. We aimed to research the marriage and childbearing behaviors of men and women with epilepsy. Methods: We conducted a cross-sectional study involving 215 adult epilepsy patients at Antalya Training and Research Hospital between 2019 and 2022. Patients were asked questions about marriage and having children on prepared questionnaires. Result: The gender distribution of the 215 patients included in the study was revealed to be 62.3% (134) females and 37.7% (81) males. 71.6% of patients were married, and 12.7% had no children. 33.3% of these patients stated that they did not desire children because of the disease. A statistically significant correlation was observed between the duration of the disease and being unmarried. A significant correlation was observed between age at disease onset and number of children. Conclusion: Our study revealed the effects of individuals with epilepsy on marriage and childbearing, and as we know, it is the first study conducted in Turkey on childbearing attitudes in individuals with epilepsy. Despite medical and social developments, epilepsy is still one of the most stigmatized diseases, and the disease has considerable negative effects on marriage and fertility. Our study supported the findings of a small number of previous similar studies on this subject and additionally showed that the likelihood of having children decreased in patients using multiple ASM, and on the other hand, it showed that marriage positively affected patients in terms of social support.

Autosomal recessive primary microcephaly type 2 associated with a novel WDR62 splicing variant that disrupts the expression of the functional transcript.

Background: Autosomal recessive primary microcephaly (MCPH) is a rare neurodevelopmental disorder characterized primarily by congenital microcephaly and intellectual disability but without extra-central nervous system malformations. This investigation aimed to elucidate the genetic underpinnings of microcephaly in a patient from a Chinese consanguineous family. Methods: A comprehensive clinical assessment, including brain magnetic resonance imaging (MRI), electroencephalogram (EEG), and genetic analyses, was conducted to evaluate the patient's condition. Whole-exome sequencing (WES) was employed to identify the causative gene, followed by Sanger sequencing, to confirm the mutation and its segregation within the family. Reverse transcript polymerase chain reaction (RT-PCR) was utilized to detect changes in splicing. Western blot was employed to reveal the difference of protein expression level between the wild-type and mutant WDR62 in vitro. Results: The patient exhibited classic MCPH symptoms, including microcephaly, recurrent epilepsy, delayed psychomotor development, and intellectual disability. Additionally, asymmetrical limb length was noted as a prominent feature. MRI findings indicated reduced brain volume with cortical malformations, while EEG demonstrated heightened sharp wave activity. A molecular analysis uncovered a novel homozygous variant c.4154-6 C > G in the WDR62 intron, and a functional analysis confirmed the pathogenicity of this mutation, resulting in the formation of an abnormal transcript with premature termination codons. Conclusion: This study enhances our understanding of the genetic heterogeneity associated with MCPH and highlights the pivotal role of genetic testing in the diagnosing and managing of rare neurodevelopmental disorders. Furthermore, it highlights the potential of emerging genetic therapies in treating conditions such as MCPH2.

Long-term impacts of a cash plus program on marriage, fertility, and education after six years in pastoralist Kenya: A cluster randomized trial.

Background: Preventing early marriage by increasing girls education has shown promise. We assessed the effects of a two-year cash plus program on marriage and fertility in a pastoralist setting in Northeastern Kenya, six years after it began. Methods: A prospective 80-cluster randomized trial followed 2,147 girls 11-14 years old starting in 2015, re-interviewing 94.2% in 2021. Interventions included community dialogues (violence prevention), a conditional cash transfer (education), health and life skills training (health), and financial literacy (wealth creation). Villages were randomized to one of four study arms: (1) violence prevention only (V-only); (2) + education (VE); (3) + health (VEH); or (4) + wealth creation (VEHW). We used analysis of covariance to estimate intent-to-treat impacts of each study arm with an education component, as well as a pooled (weighted average) study arm combining VE, VEH and VEHW, in reference to V-only, four years after the intervention ended when girls were 17-20 years old. Findings: Base specification estimates show reductions in the primary outcomes, though none statistically significant in the full sample. Estimates with extended controls are larger and the pooled study arm had significantly lower marriage and pregnancy. There are considerably larger statistically significant effects for the baseline out-ofschool subsample. Pooled estimates indicate 18.2 percentage point lower marriage compared to V-only and 15.1 percentage point lower pregnancy. For the same group pooled estimates indicate a 27.9 percentage point increase in current enrollment (compared to 7.1% in V-only) and a 1.8 grades increase (compared to 1.2 in V-only). Conclusion: This study shows the potential for interventions in early adolescence with an education component to delay marriage and fertility into late adolescence and early adulthood in a marginalized and socially conservative setting with low education and high rates of child marriage.

Drivers of child marriages for girls: A prospective study in a low-income African setting.

Child marriage has adverse consequences for young girls. Cross-sectional research has highlighted several potential drivers of early marriage. We analyse drivers of child marriage using longitudinal data from rural Malawi, where rates of child marriage are among the highest in the world despite being illegal. Estimates from survival models show that 26% of girls in our sample marry before age 18. Importantly, girls report high decision-making autonomy vis-à-vis the decision to marry. We use multivariate Cox proportional hazard models to explore the role of 1) poverty and economic factors, 2) opportunity or alternatives to marriage, 3) social norms and attitudes, 4) knowledge of the law and 5) girls' agency. Only three factors are consistently associated with child marriage. First, related to opportunities outside marriage, girls lagging in school at survey baseline have significantly higher rates of child marriage than their counterparts who were at or near grade level. Second, related to social norms, child marriage rates are significantly lower among respondents whose caregivers perceive that members of their community disapprove of child marriage. Third, knowledge of the law has a positive coefficient, a surprising result. These findings are aligned with the growing qualitative literature describing contexts where adolescent girls are more active agents in child marriages.

Seven Steps to Financial Health.

Physicians and dentists have a very limited exposure to personal financial management and yet find themselves in the top 10% of earners in the United States of America. Education loans, practice expenses, and high standards of living obligate them to be good financial stewards to succeed financially. Anecdotal personal experience and review. The article establishes seven steps to implement as medical/dental students, interns, residents, or practicing doctors to move towards financial health and security. The steps include (1) saving enough; (2) good debt management; (3) being tax savvy; (4) obtaining the correct insurance; (5) making wise investments; (6) if choosing to marry, avoid divorce; and (7) keeping track with periodic progress assessment. Each of these steps contains several components that can aid and guide physicians and dentists in their financial arc of development over their professional career and into retirement, considering generational wealth transfer or charitable donation as ultimate goals. This brief guide is based on my own financial journey to achieve long-term financial independence: start early, use simple tax deferred investments without chasing trends while keeping fees down, live within your means, and adequately insure your income.

Assessments for multi-heritage couple therapy: A review of existing tools.

As diversity in the United States increases, marriage and family therapists are encountering more multi-heritage couples in therapy. Recent research shows that around 11% of adults are married to someone from a different racial or ethnic group, rising to 19% among new marriages. Multi-heritage couples encompass inherent differences in race, ethnicity, religion, gender, sexual orientation, national origin, and culture. This article addresses the unique challenges faced by multi-heritage couples in therapy and explores the strengths and weaknesses of existing assessment tools suitable for their needs. The study highlights a limited number of existing tools that are available for therapists working with multi-heritage couples. Consequently, the article suggests future directions to enhance the development of assessment tools tailored to the specific needs of multi-heritage couples.

Path Analysis of Adverse Childhood Experiences, Early Marriage, Early Pregnancy, and Exposure to Intimate Partner Violence Among Young Women in Honduras.

Purpose: The pathways by which adverse childhood experiences (ACEs) are associated with early marriage and early pregnancy are poorly understood. Early marriage and early pregnancy may be risk factors for adulthood intimate partner violence (IPV). The aim of this study was to assess the relationships among ACEs, early marriage, early pregnancy, and IPV among women in Honduras. Method: We used weighted data from 1,436 women aged 18-24 years from the nationally representative 2017 Honduras Violence Against Children and Youth Survey. We used path analysis to estimate relationships and accounted for sample design, non-response, and within-country clustering. Results: We found that ACEs had differential relationships with outcomes of interest. For example, witnessing violence in the community was directly associated with increased probability of early pregnancy (10 percentage points (PP); 95% CI: 0.04, 0.15) and IPV (6 PP; 95% CI: 0.01, 0.10), while emotional violence was not directly or indirectly associated with any outcome. Early marriage and early pregnancy had no direct or indirect effect on IPV, but the total effect of early marriage on IPV was significant. Conclusions: Understanding the relationship between ACEs, early marriage, early pregnancy, and IPV may help inform prevention efforts. For example, programs aiming to reduce early pregnancy may consider addressing sexual violence experienced in childhood.

Cognitive Decline After Divorce and Widowhood: Is Marital Loss Always a Loss?

Background and Objectives: We used longitudinal data to determine whether the type of marital loss is associated with the rate of cognitive change before and after divorce or widowhood. Previous research found that relationship status was associated with older adults' cognitive performance: married persons performed better on memory assessments and had lower dementia risk than unmarried-cohabitating, never-married, divorced, and widowed persons. However, the end of a marriage may cause distress or reduce distress because a stressor disappears. Questions thus remain about the mechanisms by which marital change affects cognitive outcomes and, specifically, whether termination of marriage can improve cognitive performance for some. Research Design and Methods: Using data from the 1998-2016 waves of the Health and Retirement Study (N = 23,393), we conducted two analyses. First, we used trajectory analysis to create clusters of participants with similar cognitive trajectories and tested the association between participants' cluster membership and marital loss type. Second, we used multilevel modeling to analyze the relationship between participants' cognitive scores while married and following divorce or widowhood and linked these to marital features. Results: Participants who divorced showed no difference in trajectory distribution; widowed participants were more likely to be in the lower-performing and more quickly declining groups. Participants had lower rates of decline following divorce (ß = .136, p < .001), while widowed participants had accelerated decline following spousal death (ß = -0.183, p < .001) and an immediate decline following spousal death (ß = -0.113, p = .028). Discussion and Implications: We found that the type of marital loss was important, and predicted improvements in cognition for some and decrements for others, with individuals who were divorced performing best while those who were widowed or separated but not divorced performing worse.

Stability in social networks.

Dunbar's number is the cognitive limit of human beings to maintain stable relationships with other individuals in their social networks, and it is found to be 150. It is based on the neocortex size of humans. Usually, Dunbar's number and related phenomena are studied from the perspective of an individual. Dunbar's number also plays a crucial role in evolutionary psychology and allied areas. However, no study done so far has considered a couple who are in a stable relationship as a system from the perspective of Dunbar's number and its hierarchy layers. In this paper, we study the impact of Dunbar's number and Dunbar's hierarchy from the perspective of a couple by studying mathematically the conjoint Dunbar graphs for a couple. The cost of romance is the loss of almost two people from one's support network when a human being enters into a new relationship. Thus, we obtain mathematically that there is no significant change in one's friendship if human beings spend negligible time with their partners. Also, along with marriage and friendship development, we attempt to assess how a person's social network structure holds up over the course of a romantic relationship. The stability of personal social networks is discussed through soft set theory and balance theoretic approach.

A qualitative analysis and evaluation of social support received after experiencing a broken marriage engagement and impacts on holistic health.

This study provides new insights into the role of social support in the largely unexplored field of broken marriage engagements and an individual's wellbeing. The study extends the optimal matching theory (OMT) and the research surrounding helpful, unhelpful, and mixed social support. It uses constant comparison to examine the social support messages individuals received after telling others their engagement ended, as described in 43, in-depth, semi-structured interviews. Six types of helpful support messengers, six types of unhelpful support messengers, and four mixed messenger types were found. Receiver-centric messengers were found to be more helpful than messengers who centered on their own feelings and needs, sometimes to the detriment of the receiver's own wellbeing. Being present, thoughtful, and intentional with words, can have a positive impact on a person's holistic health, regardless of whether the relationship is a weak-tie or strong-tie. Using study findings, the broken engagement message stoplight is proposed, detailing messages that are generally helpful to a person's overall wellbeing, messages that should likely be avoided, and messages that should be said cautiously when interacting with someone experiencing a broken engagement.

Social acceptance and adjustment of spouses in multicultural families to reduce violent behavioral conflicts in the Mueang district, Yala province.

Currently, there is an increasing number of intercultural marriages in Thailand. Many Thai citizens, especially in various regions, tend to marry foreigners. In the southern region, particularly in the three southern border provinces, intercultural marriages mostly occur between Thai Muslim women and Thai Buddhist men. In these cases, the men usually convert to their wives' religion, Islam, which can lead to significant differences in beliefs and practices between the spouses. These differences often result in conflicts within the family and ultimately contribute to domestic violence issues. This situation has serious repercussions for both adults and children involved. This qualitative research examined the acceptance and adjustment of spouses in multicultural families to reduce violent behavioral conflicts in Muang District, Yala Province, Thailand. This study was the first research conducted in the region. To this end, data were collected through in-depth interviews, focus group discussions, and both participant and non-participant observations. Interview questions and group discussion topics were determined according to research objectives. Further, study samples were collected from multicultural Buddhist-Islamic families using the purposive sampling method. Thematic analysis was employed to analyze data. Results revealed that individuals' intolerance of each other's beliefs and attitudes was the major cause of violence in multicultural families. The values, beliefs, concepts, and attitudes of married couples are shaped by their primary and secondary socialization based on their cultural foundations. Therefore, spouses in multicultural families accept and adjust themselves holistically to reduce violent behavioral conflicts in their family life. Their acceptance includes: (1) physical acceptance and adjustment; (2) mental acceptance and adjustment; (3) social acceptance and adjustment; and (4) spiritual acceptance and adjustment. The findings have implications for intercultural marriages.

Assessing Students' Knowledge and Attitudes Regarding the Risks and Prevention of Consanguineous Marriage: A Cross-Sectional Online Survey.

Background: Several studies indicate a correlation between consanguinity and genetic disorders, congenital malformations, harm to reproductive health, and increased child mortality. Objective: To assess students' knowledge and attitudes about risks and prevention of consanguineous marriage. Methods: Demographic details of the participants and data on knowledge and attitudes concerning the risks and prevention of consanguineous marriage were obtained using an online self-administered questionnaire. The factors associated with good knowledge and attitude toward consanguineous marriage were investigated by logistic regression analysis. Results: A total of 667 participants enrolled in the study. The average knowledge score about consanguineous marriage risk and prevention was 78.6% with a 95% confidence interval (CI) [77.3, 79.8], and the average attitude was 79.7% with a 95% confidence interval (CI) [79, 80.6]. A better knowledge score was observed in older participants (OR 1.01; 95% CI 1.004-1.024), females (OR 1.69; 95% CI 1.48-1.94), participants with parental history of consanguinity (OR 1.33; 95% CI 1.17-1.52), participants with family history of consanguineous marriage (OR 5.18; 95% CI 2.19-7.10), and participants with family history of inherited disease (OR 1.52; 95% CI 1.25-1.86). Conclusion: In general, the overall level of knowledge and attitudes toward consanguineous marriage risk and prevention was good among university students. To efficiently control and manage the adverse health impacts associated with consanguineous marriage, there is an urgent need to develop and implement evidence-based counseling and screening programs for consanguineous marriage that would significantly reduce the number of at-risk marriages.

Effects of stress management and relationship-enrichment counseling on sexual and marital satisfaction of working women with high occupational stress.

BACKGROUND: Industrialization of societies has placed considerable stress on employees influencing marital and sexual satisfaction. This study investigated the effects of stress management (SM) and relationship enrichment (RE) counseling on marital and sexual satisfaction in stressed women working at Tabriz University of Medical Sciences hospitals, Iran. MATERIALS AND METHODS: In this quasi-experimental study, 75 nurses and midwives experiencing moderate-to-severe occupational stress after obtaining written informed consent were assigned to SM and RE counseling and control groups randomly. The SM and RE attended six-related counseling sessions, and control group received no intervention. The participants completed Osipow's Revised Occupational Stress Inventory (OSI-R), ENRICH Marital Satisfaction Scale, and Larson's Sexual Satisfaction Questionnaire before and 2 weeks after the intervention. The data were analyzed using one-way ANOVA and ANCOVA. RESULTS: SM counseling led to relatively good increase in sexual satisfaction. In addition, there was no significant difference between the three groups in the mean occupational stress scores and marital satisfaction scores. CONCLUSION: SM counseling increased the level of sexual satisfaction. The approaches had no significant effect on occupational stress and marital satisfaction. Further studies are required to identify the best counseling approaches.

The impact of HIV/AIDS on marriage in the early years of the epidemic.

The advent of the HIV/AIDS crisis transformed the desirability of committed heterosexual relationships. This paper employs a difference-in-differences approach to investigate the impact of the HIV/AIDS crisis on marriage rates. By using HIV/AIDS death rates as a proxy for HIV incidence, the study exploits county-level variations in HIV/AIDS mortality and finds that counties with higher HIV/AIDS death rates experienced larger gains in marriage rates in the early years of the epidemic. Estimates suggest that the virus increased marriage rates by approximately 0.9% in the early years of the virus (1981-1988).

Mechanical Hatching as a Therapeutic Intervention for Improving Implantation Rate in a 32-Year-Old Female With Recurrent Implantation Failures: A Case Report.

This case report explores the application of mechanical hatching as a successful intervention in the treatment of primary infertility for a couple with a consanguineous marriage history and recurrent implantation failure. A 32-year-old female patient and her 37-year-old spouse, after six years of unsuccessful attempts to conceive, underwent multiple intrauterine insemination (IUI) and in vitro fertilization (IVF) and embryo transfer (ET) cycles without success. Normal parameters were observed in semen analysis and hormone tests for the male and female partners, respectively. Despite a series of failed assisted reproductive technology (ART) procedures, the implementation of mechanical hatching using partial zona dissection (PZD) pipettes led to a positive pregnancy outcome. The case underscores the potential efficacy of individualized approaches, specifically mechanical hatching, in addressing challenges associated with implantation failure, offering hope to couples facing infertility issues.

Marital Quality and Depressive Symptoms Among Older Hispanic Adults in the United States.

OBJECTIVES: Despite the cultural importance of marriage as a social support system and its well-established link to mental health, older Hispanic adult populations, which are the largest racial and ethnic minoritized groups, remain understudied. The current study examined how positive and negative dimensions of marital quality are associated with depressive symptoms. METHODS: Data from Hispanic adults aged 51 years and older (n = 1,012) were obtained from the 2016 and 2018 Health and Retirement Study waves. The Center for Epidemiological Studies-Depression scale (0-8 symptoms) was modeled as a function of positive and negative marital quality measures (1-4), as well as the relevant covariates. RESULTS: Results from a negative binomial regression model showed that a 1-unit change in positive and negative marital quality was associated with a 23.61% reduction and a 23.74% increase, respectively, in depressive symptoms. The interaction terms with marital quality and gender, as well as marital quality and religion, were not statistically significant. DISCUSSION: In the United States, a large percentage of older Hispanic adults are immigrants, and their extended family tends to reside in their countries of origin. As such, older Hispanic adults may have smaller social networks, and marital quality most likely represents a culturally important social support network in later life. Significant associations between depressive symptoms and marital quality among older Hispanic adults should receive more attention in family and public health policy discussions, particularly given the increasing diversity in U.S. society.

Hearing the voices of Black Africans: Essential components for culturally relevant marriage enrichment programs in South Africa.

The literature on marriage supports teaching essential skills to enhance relationship quality and prevent divorce. However, limited marriage and relationship curricula tailored for African cultures, especially within the South African context, are currently available. This study aimed to redress gaps in literature and practice, outlining elements for inclusion into a marriage enrichment program (MEP) grounded on PREP 8.0 (Prevention and Relationship Education Program) and current baseline research conducted in South Africa. A qualitative descriptive phenomenological design was utilized, using face-to-face interviews with leaders and social services practitioners (SSPs) and a pilot study with couples, all sampled purposively. Findings show that (1) Black Africans are in high need of MEPs, revealed through intense gratitude and (2) a prerequisite for positive outcomes is the integration of equally necessary traditional contextual components with modern practices, elucidated by practical recommendations. A contextual and culturally relevant MEP is a systematic attempt to improve the functioning of marriage through education, effectively supporting Black Africans to cultivate healthy, stable family relationships.

Neural substrates of marriage on self-parents processing and the association with a parents-oriented perspective shift in a collectivistic culture.

Relationship with parents is a special bond that shapes self-other representations and have an impact on adult-child's marriage, especially in the early stages of marriage. This study sought to investigate the neural mechanisms underlying self-parents processing as well as their relationship with marriage. Seventy-eight premarital Korean participants were scanned in functional MRI while evaluating traits of the self and parents. Then, 21 of them returned after being married to engage in the identical task three years later. The precuneus and temporoparietal junction were identified to activate stronger for parents than self at both marital statuses. The dorsal anterior cingulate cortex, posterior cingulate cortex, parietal operculum, and caudate activated more for self than parents before marriage, but their activities changed during marriage. The activation increase of the parietal operculum between marital statuses in the parents condition was negatively correlated with the level of marital dissatisfaction, and this association only appeared among participants with a child. Self-parents processing may recruit brain regions involved in autobiographical memory and self-other distinction, and marriage has an impact on the way individuals process rewards and multimodal sensory information during this processing. Marriage may lead to changes in brain function that affect the processing of emotions toward parents and a more parents-oriented perspective shift in collectivistic societies.

Parental depression and their children's marriage timing: The long-term consequences of parental mental disorders.

Although decades of research documents powerful associations between parents' characteristics and their children's marital behaviors, the role of parental mental health has largely been ignored, despite the high prevalence of mental disorders and their strong potential to shape multiple dimensions of family life. Many studies examine other consequences of mothers' mental disorders, particularly for young children, but rarely do studies investigate the consequences of fathers' mental disorders, especially the potential for long-term consequences. We construct a theoretical framework for the study of intergenerational influences on family formation behaviors, integrating parental mental health, and emphasizing the potential for father's disorders to shape their children's lives. To investigate these associations, we use new intergenerational panel data featuring clinically validated diagnostic measures of parental mental health for both mothers and fathers, assessed independently. Results demonstrate that fathers' major depressive disorder is associated with significantly earlier marriage timing among sons. These important new findings provide insights into key priorities for social research on family formation processes and intergenerational influences across many domains.
