Abstract Background It is unclear whether psychotic experiences (PEs) gradually merge into states of clinical psychosis along a continuum which correspond to a dimensional classification or whether latent classes appear above a certain severity threshold which correspond better to diagnostic categories of psychosis. Methods Annual cross-sectional surveys, 2014–19, among Chinese undergraduates (N = 47,004) measured PEs, depression and etiological risk factors using standardized self-report instruments. We created a psychosis continuum with five levels and tested linear and extra-linear contrasts in associated etiological risk factors, before and after adjustment for depression. We carried out latent class analysis. Results Categorical expression of psychosis, including hallucinations and delusions, nuclear symptoms, and nuclear symptoms and depression were found at severe level 5. Etiological risk factors which impacted linearly across the continuum were more common for depression. Child maltreatment impacted extra-linearly on both psychosis and depression. Family history of psychosis impacted linearly on psychosis; male sex and urban birth impacted extra-linearly and were specific for psychosis. Four latent classes were found, but only at level 5. These corresponded to nuclear schizophrenia symptoms, nuclear schizophrenia and depressive symptoms, severe depression, and an unclassified category with moderate prevalence of PEs. Conclusion Quantitative and qualitative changes in the underlying structure of psychosis were observed at the most severe level along a psychosis continuum, where four latent classes emerged. These corresponded to existing categorical classifications but require confirmation with clinical interview. PEs are non-specific and our findings suggest some are on a continuum with depression, whilst others are on a continuum with non-affective psychosis. Differing patterns of impact from etiological risk factors across the spectrum of psychopathology determine outcome at the most severe level of these continua.

Abstract. Background and Aim: This study evaluated trauma-related shame as a mediator of the association between sexual assault severity and perceived burdensomeness and thwarted belongingness. Method: A total of 164 female undergraduates who reported attempted or completed sexual assault completed self-report measures of sexual assault, trauma-related shame, perceived burdensomeness, and thwarted belongingness. Results: Using path analysis, trauma-related shame mediated the association between sexual assault severity and perceived burdensomeness, and between sexual assault severity and thwarted belongingness. Limitations: The findings of this study are limited by the retrospective, self-report, and cross-sectional nature of these data, and do not allow for causal inference. Conclusion: Trauma-related shame warrants additional investigation as a mechanism that explains the association between sexual assault and psychosocial risk factors for suicidal ideation and behavior.

Although intimate partner violence (IPV) is often conceptualized as occurring unilaterally, reciprocal or bidirectional violence is actually the most prevalent form of IPV. The current study assessed physical IPV experiences in couples and evaluated risk and protective factors that may be differentially associated with reciprocal and nonreciprocal IPV concurrently and over time. As part of a multi-wave longitudinal study, women and men reported on the frequency of their IPV perpetration and victimization three times across the transition to parenthood. Participants also reported on risk factors related to personal adjustment, psychosocial resources, attitudes toward gender role egalitarianism, and sociodemographic characteristics at each wave. Participants were classified into one of four IPV groups (reciprocal violence, male perpetrators only, female perpetrators only, and no violence) based on their self-report and based on a combined report, which incorporated both partners’ reports of IPV for a maximum estimate of violence. Women and men were analyzed separately, as both can be perpetrators and/or victims of IPV. Cross-sectional analyses using self-reported IPV data indicated that IPV groups were most consistently distinguished by their levels of couple satisfaction, across gender; psychological distress also appeared to differentiate IPV groups, although somewhat less consistently. When combined reports of IPV were used, sociodemographic risk markers (i.e., age, income, and education) in addition to couple functioning were among the most robust factors differentiating IPV groups concurrently, across gender. In longitudinal analyses, sociodemographic vulnerabilities were again among the most consistent factors differentiating subsequent IPV groups over time. Several gender differences were also found, suggesting that different risk factors (e.g., women’s social support and men’s emotion regulation abilities) may need to be targeted in interventions to identify, prevent, and treat IPV among women and men.

Military suicide prevention efforts would benefit from population-based research documenting patterns in risk factors among service members who die from suicide. We use latent class analysis to analyze patterns in identified risk factors among the population of 2660 active-duty military service members that the Department of Defense Suicide Event Report (DoDSER) system indicates died by suicide between 2008 and 2017. The largest of five empirically derived latent classes was primarily characterized by the dissolution of an intimate relationship in the past year. Relationship dissolution was common in the other four latent classes, but those classes were also characterized by job, administrative, or legal problems, or mental health factors. Distinct demographic and military-status differences were apparent across the latent classes. Results point to the need to increase awareness among mental health service providers and others that suicide among military service members often involves a constellation of potentially interrelated risk factors.

Introduction: Although the quality of parent-child relationships is known to be associated with the offspring's mental health, little is known about the prevalence of problematic relationships in this scenario. This cross-sectional study aims to investigate the prevalence and risk factors of different types of early parent-infant relationships in a Brazilian population group. Methods: During 1 year, all families (n = 230) from an urban community of Porto Alegre, southern Brazil, with 4-month-old infants born in public hospitals were identified, and 148 were fully investigated by two family therapists. This study describes data on the 116 infants with two-parent families. Demographic, obstetric, and relational variables were collected through questionnaires and scales (Parent-Infant Relationship Global Assessment Scale, Global Assessment of Relational Functioning, and Self-Report Questionnaire). Prevalence ratios were calculated, and Poisson regression with robust variance was performed to adjust for covariates. Results: Almost 10% of mothers and 12% of fathers showed at least a significantly perturbed relationship with their 4-month-old infants. Inadequate mother-infant bonding coincided with evidence of paternal mental disorder, poor maternal social network, and discontinuation of breastfeeding at 4 months. A problematic father-infant relationship was associated with a dysfunctional couple relationship and with low infant birth weight. Conclusions: There is a high prevalence of early parent-child relationship problems, suggesting a need for health system interventions. Parent-infant relational problems are prevalent very early in life and more associated with other relational problems than with socioeconomic burden.

Abstract Background To increase our understanding of the effect of parenting on the child’s likelihood of becoming overweight, we attempted to identify typologies based on how consistently parents apply dietary and sedentary behavior rules, and we examined whether these typologies are associated with energy balance-related behaviors in children and/or with the prevalence of overweight children. Methods Data were obtained from a cross-sectional survey of the Community Health Service in Nijmegen, the Netherlands in which a total of 4,865 parents of children aged 4-12 years participated. Data were collected using validated self-report questionnaires. To identify typologies based on how consistently parents apply dietary and sedentary behavior rules, we performed latent class analyses. We then performed regression analyses to examine the correlation between these typologies and socio-demographic characteristics, dietary and sedentary behaviors, and overweight. Results Latent class analyses revealed the existence of the following four distinct, stable classes/typologies; parents who have: (1) no dietary behavior rules, plus indulgent sedentary behavior rules; (2) indulgent dietary behavior rules, plus no sedentary behavior rules; (3) overall indulgent rules; (4) overall strict rules. Children of parents with overall strict rules (class 4) had significantly healthier dietary and sedentary behaviors compared to the children of parents in the other three classes. Children 8-12 years of age with parents in class 2 were the most likely to be overweight; compared to the children of parents in classes 1, 3, and 4, the parents in class 2 had the lowest level of education and the higher number of Turkish and Moroccan immigrants. Conclusions These results underscore the need for parents to establish strict rules for their children, particularly regarding sedentary behaviour in order to minimize the child’s likelihood of becoming overweight. Key messages The results underscore the need for parents to establish strict rules for their children, particularly regarding sedentary behaviour in order to minimize the child’s likelihood of becoming overweight. These results may contribute to making healthcare professionals aware that children of parents who do not apply sedentary behavior rules are more likely to become overweight.

The aim of this study was to estimate the prevalence and risk factors for self-reported diabetes mellitus (DM) in the adult population of the Central-West region of Brazil. In 2013, a cross-sectional study using the data from the National Health Survey and comprising 7519 individuals aged ≥18 years from the Central-West region was conducted. Participants were interviewed at their homes about sociodemographic data and risk factors for DM. To verify the risk factors with DM, the Poisson regression model was used. The analyses were performed for the total sample and stratified according to sex. The prevalence of DM was 6.5% (95% confidence interval [95% CI], 5.7–7.3). The diagnosis of self-reported DM was 4.3% in men and 7.5% in women. In the global sample, it was found that age between 40–59 years and ≥60 years, previous smoking (former smoker), self-reported hypertension, self-reported dyslipidemia, overweight, and obesity were independently associated with self-reported DM. In men, risk factors were: Age ≥ 60 years, self-reported hypertension, self-reported dyslipidemia, and obesity. In women, risk factors were: Age 30–39 years, 40–59 years, and ≥60 years, previous smoking (former smoker), self-reported hypertension, self-reported dyslipidemia, overweight, and obesity. Conclusion: The prevalence of DM was 6.5%. DM was associated with advanced age; previous smoking (former smoker), hypertension, dyslipidemia, overweight, and obesity. Some differences in risk factors between men and women were noted.

Domestic Violence Against Women

Purpose The purpose of this paper is to determine the prevalence of domestic violence against women and its related factors in Sanandaj, west of Iran. Design/methodology/approach This is a cross-sectional study conducted in 2016. The sample consisted of 360 women who referred to two educational hospitals in Sanandaj. The data collection tool was a self-report questionnaire. A multivariate logistic regression was used to determine the risk factors of domestic violence against women. Findings The prevalence of “any form of violence” in the past year was 71 percent (n=245). The prevalence of emotional, sexual and physical violence was 62.2 percent (n=225), 48.7 percent (n=168) and 49.9 percent (n=172), respectively. Multivariate logistic regressions revealed that the “any form of violence” has significant association with occupation of women, economic status of family and the status of sexual satisfaction of couples. Originality/value The prevalence of domestic violence against women is high and alarming in Sanandaj, Iran. Given the relationship between experience of violence and sexual dissatisfaction, sexual education before and after marriage is recommended for couples. Also, the experience of exposure to violence in women can be included in health centers as screening programs. In this way, couples who have risk factors will receive the educational programs.

SYNOPSISIn a case-control study, two potential interpersonal risk factors of non-endogenous depression, namely a patient's perception of their current intimate partner as dysfunctional and a patient's recall of exposure to previous deprivational parenting, were quantified. The interpersonal characteristics of the partner were assessed principally by a brief self-report questionnaire, the Intimate Bond Measure (IBM). By cross-sectional and longitudinal comparison of this instrument with other interview-derived and self-report measures, the convergent, discriminant and predictive validity of the IBM in depressed patients was established. Further, little evidence of any distorting effect of depressed mood or neuroticism was detected. The perception of the current intimate partner as dysfunctional imparted a risk to non-endogenous depression of at least five times, while reported exposure to parental ‘affectionless control’ was quantified as a four times' risk. Importantly, IBM care scores predicted the course of the depressive disorder over a six-month period.

BackgroundThe size and mean age of the prison population has increased rapidly in recent years. Prisoners are a vulnerable group who, compared with the general population, experience poorer health outcomes. However, there is a dearth of research quantifying the prevalence of non-communicable diseases (NCDs) among prisoner populations.AimTo explore both the prevalence of NCDs and their risk factors.Design & settingA cross-sectional survey was undertaken that was compared with clinical records in two male prisons in the north of England.MethodSelf-report surveys were completed by 199 prisoners to assess sociodemographic characteristics, general health, NCD prevalence, and risk factor prevalence. Data were checked against that retrieved from prison clinical records.ResultsIt was found that 46% reported at least one NCD and 26% reported at least one physical health NCD. The most common self-reported NCD was 'anxiety and depression' (34%), followed by 'respiratory disease' (17%), and 'hypertension' (10%). Having a physical health NCD was independently associated with increasing age or drug dependence.The level of agreement between clinical records and self-report ranged from 'fair' for alcohol dependence (kappa 0.38; P<0.001) to 'very good' for diabetes (kappa 0.86; P<0.001).ConclusionCompared with mainstream populations and despite high prevalence of risk factors for NCDs physical illness NCDs, with the exception of respiratory disease, are less common. However, poor mental health is more common. These differences are possibly owing to the younger average age of prison populations, since prevalence of risk factors was reported as high.Secondary data analysis of clinical records is a more methodologically robust way of monitoring trends in prisoner population disease prevalence.

Current Asthma

BackgroundSouth Africa has undergone major economic and health system changes impacting the epidemiology of childhood asthma. This study aimed to investigate prevalence time-trends of asthma in South African adolescents over 2 decades and to identify associated risk-factors.MethodsA cross-sectional survey was conducted in 2017, in a randomised sample of 13–14 year-old Cape Town adolescents, using the standardised Global Asthma Network written, video, and environmental questionnaires. Using time-trend analysis, the prevalence and severity of asthma were compared with data from the 2002 ISAAC phase III study. Environmental and social risk-factors were analysed.Results3979 adolescents were included. Prevalence of lifetime and current asthma were 34.5% and 21.3%, respectively, on the self-report written questionnaire, similar to 2002 results. The prevalence of severe asthma in the last 12 months increased, measured by wheeze limiting speech (7.8% to 11.8%), ≥4 attacks of wheezing (5.0% to 5.8%) or ≥1 night·week−1 waking from wheezing (5.0% to 6.9%). The video questionnaire revealed increases in lifetime (16.9% to 22.5%), current (11.2% to 18.7%), or severe asthma (12.1% to 14.8%). Multivariate analysis showed associations between current asthma and smoking, female sex, pet exposure or higher socioeconomic status. Severe asthma was associated with smoking, pet exposure, outdoor pollution exposure or informal housing. 33% of those with severe or current asthma had been diagnosed.ConclusionThe prevalence of asthma is high, with increasing rates of severe asthma in adolescents. Underdiagnosis is a major concern and reduction in exposure to environmental factors, particularly smoking, and improved socioeconomic development are needed.
