Arranged cohabitation among Chinese Muslims.

While modern family-related ideas and behaviors have become more widely accepted in contemporary China, Chinese Muslim minorities continue to hold on to traditional religious practices. Surprisingly, data from our survey conducted in Gansu province in China's northwestern borderlands reveal that Muslims of the Hui and Dongxiang ethnicities reported much higher rates of cohabitation experience than the secular majority Han. Based on follow-up qualitative interviews, we found the answer to lie in the interplay between the highly interventionist Chinese state and the robust cultural resilience of local Islamic communities. While the state maintains a high minimum legal age of marriage, the early marriage norm remains strong in Chinese Muslim communities, where religion constitutes an alternative and often more powerful source of legitimacy-at least in the private sphere of life. Using the 2000 census data, we further show that women in almost all 10 Muslim ethnic groups have higher percentages of underage births and premarital births than Han women, both nationally and in the northwest where most Chinese Muslims live. As the once-outlawed behavior of cohabitation became more socially acceptable during the reform and opening-up era, young Muslim Chinese often found themselves in "arranged cohabitations" as de facto marriages formed at younger-than-legal ages. In doing so, Chinese Muslim communities have reinvented the meaning of cohabitation. Rather than liberal intimate relationship based on individual autonomy, cohabitation has served as a coping strategy by which Islamic patriarchs circumvent the Chinese state's aggressive regulations aimed at "modernizing" the Muslim family.

Impact of parenthood on eating pathology in young adults.

OBJECTIVE: Few studies investigated parenthood as a predictor of eating pathology in young adulthood. We studied the association between parenthood, in the first year after becoming a parent and beyond, and eating pathology. Furthermore, we examined whether moving in together with a partner affected this association. METHOD: This study used data of four measurement waves from TRAILS (Tracking Adolescents' Individual Lives Survey), a Dutch community cohort study (N = 2229) from preadolescence into young adulthood. The Eating Disorder Diagnostic Scale (EDDS), a measure to assess eating pathology, was assessed at ages 22, 26, and 29. Risk for eating disorder was assessed at age 19. Pregnant participants were excluded. RESULTS: Parenthood was not associated with an increase of eating pathology in the first year after becoming a parent and beyond. Instead, parents were more likely to report being free from eating pathology symptoms compared to childless individuals (OR 2.07, 95% CI: 1.11-3.84). Among those who reported experiencing at least one eating problem, parenthood was not associated with the number of eating problems. Moving in together with a partner did not alter the association between parenthood and eating problems and neither did this association differ between males and females. DISCUSSION: Parenthood in young adulthood was associated with a decreased risk of having eating pathology. PUBLIC SIGNIFICANCE STATEMENT: In this longitudinal study among young adults, parenthood was not associated with the development of eating pathology.

Trajectories of relationship and sexual satisfaction over 2 years in the Covid-19 pandemic: A latent class analysis.

OBJECTIVE: Previous research on the impact of the Covid-19 pandemic on romantic relationships has mainly concentrated on short-term effects and average trends of change. This study aimed to explore different trajectories of relationship and sexual satisfaction from April 2020 to March 2022. METHOD: Including a cross-national sample of 2859 individuals, a latent class approach was applied to identify subgroups of sexual and relationship satisfaction trajectories. Participants' satisfaction levels, attachment style, psychological symptoms, life satisfaction, and living arrangements were taken into account. RESULTS: Three latent classes were identified for both relationship and sexual satisfaction: (1) a group with high satisfaction levels but a slightly declining trajectory, (2) a group with low satisfaction levels but an ascending trajectory, and (3) a fluctuating group. Living apart, having children, psychological symptoms, low life satisfaction, and avoidant attachment characterized the two groups with low or fluctuating trajectories. CONCLUSIONS: The findings suggest that there were different trajectories of relationship and sexual satisfaction during the pandemic, which can be predicted by individual dispositions. Even 2 years after the pandemic, its effects had not disappeared.

Rising nonmarital first childbearing among college-educated women: Evidence from three national studies.

Levels of nonmarital first childbearing are assessed using recent administrations of the National Longitudinal Survey of Youth, 1997 Cohort; the National Longitudinal Study of Adolescent to Adult Health; and the National Survey of Family Growth. Results confirm that the higher a woman's educational attainment, the less likely she is to be unmarried at the time of her first birth. A comparison over time shows increases in nonmarital first childbearing at every educational level, with the largest percentage increase occurring among women with college degrees at the BA or BS level or higher. This article projects that 18 to 27% of college-educated women now in their thirties who have a first birth will be unmarried at the time. In addition, among all women who are unmarried at first birth, women with college degrees are more likely to be married at the time of their second birth, and, in a majority of cases, the other parent of the two children was the same person. A growing proportion of well-educated women, and their partners, may therefore be pursuing a family formation strategy that proceeds directly to a first birth, and then proceeds, at a later point, to marriage, followed by a second birth. Possible reasons for the increase in nonmarital first births among the college-educated include the stagnation of the college wage premium; the rise in student debt; decreasing selectivity; and the growing acceptability of childbearing within cohabiting unions, which have become a common setting for nonmarital childbearing, and among single parents.

'It would be a problem for the family': queerness, family honour and familism in Chile.

Family honour, protecting and upholding the family name, is central to familism. Yet, it has been somewhat neglected by scholarship on Latin American and Latino families. Familism involves prioritising the family over the individual. Likewise, the family of origin holds particular significance, offering material, social and emotional support, and shaping one's identity, honour and sense of belonging. Heteronormativity and patriarchy portray queer individuals as the causes of family shame. This study examined how family honour, as a component of familism, operates within kin dynamics, specifically focusing on same-sex cohabitation, as this living arrangement serves as a tangible expression of a non-normative sexual orientation. A life course perspective was used to study 24 cases of cohabiting lesbian, gay and bi/pansexual individuals in Chile. The results show the enduring significance of families in providing support, sociability, identity, and a sense of belonging. Nevertheless, it reveals notable instances of family rejection towards queer kin. In Chile, both families of origin and queer individuals employ subtle strategies to conceal their queerness, guided by notions of 'respect' associated with family honour and decency. These strategies involve unspoken agreements to maintain family bonds through discreet displays of queer behaviour without explicit acknowledgement of sexual identity.

A matter of time: Bateman's principles and mating success as count and duration across social strata in contemporary Finland.

Bateman's principles heavily influence the understanding of human reproductive behaviour. Yet, few rigorous studies on Bateman's principles in contemporary industrialized populations exist. Most studies use small samples, exclude non-marital unions, and disregard recent insights on within-population heterogeneity in mating strategies. We assess mating success and reproductive success using population-wide Finnish register data on marital and non-marital cohabitations and fertility. We examine variability across social strata in the Bateman principles and analyse the mate count, the cumulated duration with a mate, and the association with reproductive success. Results support Bateman's first and second principles. Regarding Bateman's third principle, the number of mates is more positively associated with reproductive success for men than women, but this association is driven by ever having a mate. Having more than one mate is on average associated with lower reproductive success. However, for men in the lowest income quartile, having more than one mate positively predicts reproductive success. Longer union duration is associated with higher reproductive success, and more so for men. We note that sex differences in the relationship between mating success and reproductive success differ by social strata, and argue that mate duration may be an important component of mating success alongside mate count.

Socio-economic functioning in patients with bipolar disorder and their unaffected siblings - results from a nation-wide population-based longitudinal study.

BACKGROUND: Few studies have reported real-life data on socio-economic functioning in patients with bipolar disorder and their unaffected first-degree relatives. METHODS: We used Danish nation-wide population-based longitudinal register linkage to investigate socio-economic functioning in 19 955 patients with bipolar disorder, their 13 923 siblings and 20 sex, age and calendar-matched control individuals from the general population. Follow-up was from 1995 to 2017. RESULTS: Patients with a diagnosis of bipolar disorder had lower odds of having achieved the highest educational level [OR 0.75 (95% confidence interval (CI) 0.73-0.77)], being employed [OR 0.16 (95% CI 0.159-0.168)], having achieved the 80% highest quartile of income [OR 0.33 (95% CI 0.32-0.35)], cohabitating [OR 0.44 (95% CI 0.43-0.46)] and being married [OR 0.54 (95% CI 0.52-0.55)] at first contact to hospital psychiatry as inpatient or outpatient compared with control individuals from the general population. Similarly, siblings to patients with bipolar disorder had a lower functioning within all five socio-economic areas than control individuals. Furthermore, patients and partly siblings showed substantially decreased ability to enhance their socio-economic functioning during the 23 years follow-up compared to controls. CONCLUSIONS: Socio-economic functioning is substantially decreased in patients with bipolar disorder and their siblings and does not improve during long-term follow-up after the initial hospital contact, highlighting a severe and overlooked treatment gap.

Are education and cohabitation associated with health-related quality of life and self-management during breast cancer follow-up? A longitudinal study.

BACKGROUND: Oncologist-led follow-up after breast cancer (BC) is increasingly replaced with less intensive follow-up based on higher self-management, which may overburden the less resourceful patients. We examined whether socioeconomic factors measured recently after the implementation of a new follow-up program for BC patients were associated with health-related quality of life (HRQoL) and self-management 12 months later. METHODOLOGY: Between January and August 2017, we invited 1773 patients in Region Zealand, Denmark, to participate in baseline and 12 months follow-up questionnaires. The patients had surgery for low- and intermediate risk BC 1-10 years prior to the survey, and they had recently been allocated to the new follow-up program of either patient-initiated follow-up, or in-person or telephone follow-up with a nurse, based on patients' preferences. We examined associations between socioeconomic factors (education and cohabitation) at baseline and two outcomes: HRQoL (EORTC QLQ-C30 and QLQ-BR23) and self-management factors (health care provider, confidence in follow-up, contact at symptoms of concern, and self-efficacy) at 12 months follow-up. Sensitivity analyses were performed according to time since diagnosis (≤ 5 > 5 years). Furthermore, we investigated whether treatment and self-management factors modified the associations. RESULTS: A total of 987 patients were included in the analyses. We found no statistically significant associations between socioeconomic factors and HRQoL, except in patients ≤ 5 years from diagnosis. For self-management patients with short education were more likely to report that they had not experience relevant symptoms of concern compared to those with medium/long education (OR 1.75 95% CI: 1.04; 2.95). We found no clear patterns indicating that treatment or self-management factors modified the associations between socioeconomics' and HRQoL. CONCLUSION: Overall socioeconomic factors did not influence HRQoL and self-management factors except for experiencing and reporting relevant symptoms of concern. Socioeconomic factors may, however, influence HRQoL in patients within five years of diagnosis.

Childhood Family Instability and Young-Adult Union Experiences: Black-White Differences in Outcomes and Effects.

Today's young adults have diverse union experiences; some enter enduring marital or cohabiting unions at young ages, but many delay or dissolve their unions or remain single. Childhood family instability-defined as parents' transitions into or out of romantic coresidential unions-offers one explanation for why some people are more likely than others to enter and exit unions. We evaluate whether this family instability hypothesis-a union-specific version of the general hypothesis that instability affects people across multiple life domains-can explain Black and White young adults' union formation and dissolution. Using data from the Panel Study of Income Dynamics' Transition into Adulthood Supplement (birth cohorts 1989-1999), we find that the marginal effects of childhood family instability on cohabitation and marriage are weaker for Black than for White youth. Further, Black-White differences in childhood family instability's prevalence are small. Consequently, novel decompositions that account for racial differences in instability's prevalence and marginal effects reveal that childhood family instability contributes little to Black-White inequality in young adults' union outcomes. Our results challenge the generalizability of the family instability hypothesis across racialized groups in the union domain. Explanations for Black-White differences in young-adult marriage and cohabitation reside beyond childhood family dynamics.

Transition in the ages at key reproductive events and its determinants in India: evidence from NFHS 1992-93 to 2019-21.

INTRODUCTION: Reproductive health events have changed fertility and family planning needs, depicting the changing life patterns of women and the population to which they belong. Understanding the pattern at which these events occur helps in understanding the fertility pattern, family formation and the idea about health essential needs for women. This paper attempts to see the variation in reproductive events (first cohabitation, first sex and first birth) over three decades and also to see potential contributing factors among the reproductive age group of women using secondary data from Data Source: All rounds of the National Family Health Survey (1992-93 to 2019-2021) have been utilized. METHODS AND RESULTS: Cox Proportional Hazard Model illustrates that all regions have initiated their first birth later than women who belong to the east region similar pattern has been obtained for first cohabitation and first sex except for the central region. Multiple Classification Analysis (MCA) depicts the increasing pattern in the predicted mean age at first cohabitation, sex and birth for all demographic characteristics; the highest increment was found in SC women, Uneducated women and Muslim women. Kaplan Meier Curve demonstrates that women with no education, primary or secondary education are shifting towards higher educated women. Most importantly, the results of the multivariate decomposition analysis (MDA) revealed that education played the largest contribution among the compositional factors in the overall increase in mean ages at key reproductive events. CONCLUSIONS: Though reproductive health has long been essential in women's lives, they are still very confined to specific domains. Over time the government has formulated several proper legislative measures relating to various domains of reproductive events. However, given that the large size and heterogeneity in social and cultural norms result in changing ideas and choices regarding the initiation of reproductive events, national policy formulation needs to be improved or amended.

Social position and functional somatic disorders: The DanFunD study.

BACKGROUND AND AIM: It is generally accepted that functional somatic disorders (FSDs) are a product of biological, psychological, and social factors. Social position might be part of this complex, but the literature on this issue is currently heterogeneous and inconsistent. The aim of the present study was - in a population-based cohort - to test the hypothesis that lower social position would be associated with higher a risk of FSD. METHOD: The association between social position and FSD was examined in a cross-sectional study with various measures of social position (education as measured by vocational training; employment; cohabitation; subjective social status) and delimitations of FSD (irritable bowel syndrome, chronic fatigue syndrome, fibromyalgia, bodily distress syndrome, and symptom profiles). The associations were analyzed using logistic regressions to calculate odds ratios and 95% confidence intervals. Each social measure was analyzed independently and was adjusted for age and sex. RESULTS: Lower levels of vocational training, being unemployed, and living alone were associated with higher risk of FSD, regardless of the FSD delimitation. There was also a significant negative association between subjective evaluated social status and FSD. The associations remained after multiple adjustments, and seemed to be strongest for the more severe FSD-types. CONCLUSIONS: Lower social position is associated with higher risk of FSD, especially the more severe FSD delimitations, which might constitute an especially vulnerable group. However, the mechanisms behind the relations remain unknown.

Mental health benefits of cohabitation and marriage: A longitudinal analysis of Norwegian register data.

The aim is to examine how mental health is affected by cohabitation and marriage. Individual fixed-effects models are estimated from Norwegian register data containing information about consultations with a general practitioner because of mental health conditions in 2006-19. Mental health, as indicated by annual number of consultations, improves over several years before cohabitation. For those marrying their cohabiting partner, there is a weak further reduction in consultations until the wedding, but no decline afterwards. In other words, formalization of the union does not seem to confer additional mental health benefits. However, marriage may be considered a marker of favourable earlier development in mental health. In contrast, there is further improvement after direct marriage, as well as stronger improvement over the years just preceding direct marriage. Patterns are quite similar for women and men. Overall, the results suggest that the mental health benefits of cohabitation and marriage are similar.Supplementary material for this article is available at: https://dx.doi.org/10.1080/00324728.2022.2063933.

Uncertain steps into adulthood: Does economic precariousness hinder entry into the first co-residential partnership in the UK?

This study uses prospective data spanning 27 years (1991-2018) to explore the relationship between economic precariousness and transitions to first co-residential partnership among Britons aged 18-34 across three dimensions: age, historical time, and sex. Economic precariousness is measured using eight objective and subjective indicators, including income, employment, housing, and financial perceptions. Our results show that economic precariousness has a strong negative relationship with entering the first co-residential partnership among those aged 20-30, but the pattern is less clear among the youngest and oldest. Objective measures are easier to interpret than subjective measures. Historical analyses suggest that not being employed decreases the probability of union formation more in recessionary periods than in non-recessionary ones. Among working women, low labour income started to be a predictor of union formation in the most recent periods. Labour income is the only indicator presenting trends in line with our hypotheses across all dimensions.

Unpacking the linkages between single parent households and early adolescent adjustment.

Living with an unmarried mother is consistently associated with adjustment issues in adolescence, but these associations can vary by both time and place. Following life course theory, this study applied inverse probability of treatment weighting techniques to data from the National Longitudinal Survey of Youth (1979) Children and Young Adults study (n = 5,597) to estimate various treatment effects of family structures through childhood and early adolescence on internalizing and externalizing dimensions of adjustment at age 14. Young people who lived with an unmarried (single or cohabiting) mother during early childhood and adolescence were more likely to drink and reported more depressive symptoms by age 14 than those with a married mother, with particularly strong associations between living with an unmarried mother during early adolescence and drinking. These associations, however, varied according to sociodemographic selection into family structures. They were strongest for youth who more closely resembled the average adolescent living with a married mother.

Do Personality Traits Moderate the Effects of Cohabitation, Separation, and Widowhood on Life Satisfaction? A Longitudinal Test for Germany.

The start and end of a romantic relationship are associated with substantial changes in life satisfaction. Yet, whether Big Five personality traits moderate these relationship transition effects is hardly known. Such knowledge helps to understand individual variation in relationship transition effects and provides the possibility to further test the stress and social support explanations of these effects. Our fixed effects regressions on 28 waves of the German Socio-Economic Panel 1991-2018 show that Big Five traits moderate the effects of relationship transitions on life satisfaction to a limited extent. More neurotic men display a more negative effect of separation, and more neurotic and more agreeable women reveal a more negative effect of widowhood on life satisfaction. Big Five traits do not moderate the effect of the start of cohabitation on life satisfaction. Our findings support the stress perspective of relationship transition effects most and identify emotionally unstable individuals as a particularly vulnerable group.

Cohabitation and Marriage Among Same-Sex Couples in the 2019 ACS and CPS: A Research Note.

Since the 2015 U.S. Supreme Court ruling that marriages of same-sex couples are legal in all states in the union, federal surveys have adapted to the shifting legal climate and included new measures that more directly identify same-sex and different-sex cohabiting and married couples. In this research note comparing the largest and most recent federal surveys-the 2019 American Community Survey and Current Population Survey-we find consistent levels of cohabitation and marriage across surveys. While the vast majority (90%) of different-sex couples were married, we report a more even split in cohabitation and marriage among same-sex couples. Our evaluation of sociodemographic characteristics of married and cohabiting couples indicates that differences were less prominent among same-sex couples than among different-sex couples, suggesting weaker sociodemographic selection into marriage among the former. However, factors affecting same-sex and different-sex couples' decisions to live together and marry may differ because of legal and social climates that still present unique obstacles for same-sex couples. Researchers need to acknowledge these differences in assessments of the implications of marriage for health and well-being.

Intra vitam assays for detecting fish infected with cyprinid herpesvirus 3 (CyHV-3).

Koi carp is one of the most sensitive variants of common carp Cyprinus carpio to cyprinid herpesvirus 3, commonly known as koi herpesvirus (KHV). Given that this species is traded at high prices throughout the world, intra vitam assays for detecting KHV in targeted fish with a high detection efficiency are essential. In this study, 4 intra vitam assays were compared with regard to their efficiency of detecting KHV in koi carp on each day after viral exposure via experimental infection. The results indicated that PCR from the gills and scales sampled by biopsy using dissecting scissors and forceps, respectively, can detect KHV for apparently longer periods than the other assays. This study also suggests that a PCR detection assay for environmental samples could be developed as a convenient intra vitam assay to confirm the presence of virus in environments inhabited by virus-shedding fish.

Experimental infection trials with European North Atlantic ranavirus (Iridoviridae) isolated from lumpfish (Cyclopterus lumpus, L.).

European North Atlantic ranavirus (ENARV, Iridoviridae), is a ranavirus species recently isolated from lumpfish (Cyclopterus lumpus, L.), which are used as cleaner fish in Atlantic salmon (Salmo salar) farming in Northern Europe. This study aimed to investigate (1) the virulence of ENARV isolates from Ireland, Iceland and the Faroe Islands to lumpfish; (2) horizontal transmission between lumpfish; and (3) virulence to Atlantic salmon parr. Lumpfish were challenged in a cohabitation model using intraperitoneally (IP) injected shedders, and naïve cohabitants. IP challenge with isolates from Iceland (1.9 × 107 TCID50  ml-1 ) and the Faroe Islands (5.9 × 107 TCID50  ml-1 ) reduced survival in lumpfish, associated with consistent pathological changes. IP challenge with the Irish strain (8.6 × 105 TCID50  ml-1 ) did not significantly reduce survival in lumpfish, but the lower challenge titre complicated interpretation. Horizontal transmission occurred in all strains tested, but no clinical impact was demonstrated in cohabitants. Salmon parr were challenged by IP injection with the Irish isolate, no virulence or virus replication were demonstrated. A ranavirus qPCR assay, previously validated for fish ranaviruses, was first used to detect ENARV in tissues of both in lumpfish and Atlantic salmon. This study provides the first data on the assessment of virulence of ENARV isolates to lumpfish and salmon, guidelines for the diagnosis of ENARV infection, and poses a basis for further investigations into virulence markers.

Trajectories of adolescent poly-substance use and their long-term social and economic outcomes for males from low-income backgrounds.

Substance abuse is a significant public health concern that disproportionately burdens males and low-income communities. This study examined (1) longitudinal profiles of male adolescent poly-substance use and (2) their association with social and economic participation across early adulthood. Drawing on a cohort of males (n = 890) from low-income neighborhoods, we used group-based multi-trajectory modeling to identify profiles of poly-substance use (alcohol, tobacco, cannabis, illicit drugs) from age 13-17 years. Regression models were used to link substance use profiles to high school graduation, criminal convictions, personal and household earnings, welfare receipt and partnership from age 19-37 years, obtained from administrative records. Child IQ, family adversity and behavioral problems were adjusted for. Four poly-substance use profiles were identified: abstinent (n = 128, 14.4%), late-onset (n = 412, 46.5%), mid-onset (n = 249, 28.1%), and early-onset (n = 98, 11.1%). Relative to the late-onset (reference) group, participants in the early-onset profile were 3.0 times (95%CI = 1.68-5.53) more likely to have left school without a diploma, 2.7 times (95% CI = 1.56-4.68) more likely to have a criminal conviction by age 24 years, earned 10,185 USD less (95% CI = - 15,225- - 5144) per year at age 33-37 years and had 15,790 USD lower (95% CI = - 23,378- - 8218) household income at age 33-37 years, a 1.3 times (95%CI = 1.15-1.57) higher incidence of annual welfare receipt and a 24% (95% CI = 5-40) lower incidence of marriage/cohabitation from age 18-35 years. We show that adolescent-onset poly-substance use by age 13 is associated with poor social and economic outcomes. Delaying the onset of substance use and reducing exposure to additional substance classes has potential for high societal cost savings.

Is cohabitation as a form of union formation a licence to intimate partner physical violence in Uganda?

The study examined the argument that cohabitation as a form of union increases physical violence victimization among women. The study's aim was to assess the association between physical violence and other socio-demographic factors that influence physical violence among women. Self-reported data were extracted from the 2016 Uganda Demographic and Health Survey (UDHS), with a sample of 2479 couples, from the couple file. Chi-squared tests and multivariate Firth-logit regression models were used to examine the relationship between intimate partner violence (IPV) victimization and marital status controlling for other social-demographic factors. There was no significant evidence that women in cohabiting union have a higher risk of exposure to physical violence in the Ugandan context. The risk of experiencing physical violence perpetration varied by birth cohort, with the most recent cohorts exhibiting a slightly higher risk of experiencing partner violence than previous cohorts. Significant factors found to be associated with an increased risk of experiencing IPV included being in the poorer, middle and richer compared with the poorest wealth tertile of income, residing in Eastern or Northern regions compared with the Central region, being affiliated to the Catholic faith compared with Anglican and having five or more children compared with 4 or fewer children. In conclusion, there is no evidence that physical violence is more pronounced among women in cohabiting unions compared with married women in Uganda.
