Stigma perceived by patients with functional somatic syndromes and its effect on health outcomes - A systematic review

BACKGROUND: Patients with functional somatic syndromes (FSS) experience stigma which arguably affects their health. AIM: To determine the presence of perceived stigma and its effects on physical and mental health in patients with FSS compared to patients with comparable explained conditions. METHODS: A comprehensive search of PubMed, Embase, PsycINFO, CINAHL and Cochrane Library was performed to select studies focusing on stigma perceived by patients with irritable bowel syndrome (IBS), fibromyalgia (FM) or chronic fatigue syndrome (CFS), comparing these patients to patients with comparable but explained conditions. RESULTS: We identified 1931 studies after duplicate removal. After screening we included eight studies: one study about all three FSS, one about IBS, five about FM and one about CFS. We found that patients with IBS did not consistently experience higher levels of stigma than those with a comparable explained condition. Patients with CFS and FM experienced higher levels of stigma compared to patients with comparable explained conditions. All studies showed a correlation between stigma and negative health outcomes. DISCUSSION: Patients with FSS experience stigma and negative health outcomes. However, experiencing stigma is not restricted to patients with FSS, as many patients with explained health conditions also experience stigma. Whether stigma has more negative health consequences in patients with FSS compared to patients with explained health conditions remains unclear and should be assessed in future research

Female sex and femininity independently associate with common somatic symptom trajectories

BACKGROUND: Multiple predictors have been associated with persistent somatic symptoms. However, previous studies problematically defined the persistence of symptoms, conflated participants' sex and gender, and focused on patient populations. Therefore, we studied associations between predictors, especially sex and gender, and longitudinal patterns of somatic symptoms in the general adult population. We also assessed whether predictors for persisting symptoms differ between sexes. METHOD: To identify developmental trajectories of somatic symptoms, assessed by the SCL-90 SOM, we used latent class trajectory modeling in the Dutch Lifelines Cohort Study [N = 150 494; 58.6% female; median time to follow-up: 46.0 (min-max: 22.0-123.0) months]. To identify predictors of trajectories, we applied multiple logistic regression analyses. Predictors were measured by surveys at baseline and a composite gender index was previously developed. RESULTS: A five-class linear LCGA model fitted the data best: 93.7% of the population had a stable symptom trajectory, whereas 1.5% and 4.8% of the population had a consistently increasing or decreasing symptom trajectory, respectively. Female sex predicted severe, stable symptom severity (OR 1.74, 95% CI 1.36-2.22), but not increasing symptom severity (OR 1.15, 95% CI 0.99-1.40). Femininity was protective hereof (OR 0.60, 95% CI 0.44-0.82 and OR 0.66, 95% CI 0.51-0.85, respectively). Merely a few predictors of symptom severity, for instance hours of paid employment and physical functioning, differed in strength between sexes. Yet, effect sizes were small. CONCLUSION: Female sex and femininity predict symptom trajectories. No large sex differences in the strength of additional predictors were found, thus it may not be clinically useful to distinguish between predictors specific to male or female patients of persistent somatic symptoms

Do women and men use language differently in spoken face-to-face interaction? A scoping review

Although the question of whether women and men speak differently is a topic of hot debate, an overview of the extent towhich empirical studies provide robust support for a relationship between sex/gender and language is lacking. Therefore, the aim of the current scoping review is to synthesize recent studies from various theoretical perspectives on the relationship between sex/gender and language use in spoken face-to-face dyadic interactions. Fifteen empirical studies were systematically selected for review, and were discussed according to four different theoretical perspectives and associated methodologies. More than thirty relevant linguistic variables were identified (e.g., interruptions and intensifiers). Overall, few robust differences between women and men in the use of linguistic variables were observed across contexts, although women seem to be more engaged in supportive turn-taking than men. Importantly, gender identity salience, institutionalized roles, and social and contextual factors such as interactional setting or conversational goal seem to play a key role in the relationship between speaker’s sex/gender and language used in spoken interaction

Sex differences in the trajectories to diagnosis of patients presenting with common somatic symptoms in primary care:an observational cohort study

Objective: Little insight exists into sex differences in diagnostic trajectories for common somatic symptoms. This study aims to quantify sex differences in the provided primary care diagnostic interventions for common somatic symptoms, as well as the consequences hereof for final diagnoses. Methods: In this observational cohort study, we used real-world clinical data from the Dutch Family Medicine Network (N = 34,268 episodes of care related to common somatic symptoms; 61,4% female). The association between patients' sex on the one hand, and diagnostic interventions and disease diagnoses on the other hand, were assessed using multilevel multiple logistic regression analyses. Structural equation modelling was used to estimate a mediation model with multiple parallel mediators to assess whether the fewer disease diagnoses given to female patients were mediated by the fewer diagnostic interventions female patients receive, compared to male patients. Results: Women received fewer physical examinations (OR = 0.84, 95%CI = 0.79-0.89), diagnostic imaging (OR = 0.92, 95%CI = 0.84-0.99) and specialist referrals (OR = 0.85, 95%CI = 0.79-0.91) than men, but more laboratory diagnostics (OR = 1.27, 95%CI = 1.19-1.35). Women received disease diagnoses less often than men for their common somatic symptoms (OR = 0.94, 95%CI = 0.89-0.98). Mediation analysis showed that the fewer disease diagnosis in female patients were mediated by the fewer diagnostic interventions conducted in women compared to men. Conclusion: This study shows that sex inequalities are present in primary care diagnostic trajectories of patients with common somatic symptoms and that these lead to unequal health outcomes in terms of diagnoses between women and men. FPs have to be aware of these inequalities to ensure equal high-quality care for all patients

Gender and sex independently associate with common somatic symptoms and lifetime prevalence of chronic disease

Contains fulltext : 225526.pdf (Publisher’s version ) (Open Access)Sex and gender influence health differently. Associations between sex and health have been extensively studied, but gender (i.e. psychosocial sex) has been largely neglected, partly due to the absence of gender measures in cohort studies. Therefore, our objective was to test the unique associations of gender and sex with common somatic symptoms and chronic diseases, using a gender index created from existing cohort data. We applied LASSO logistic regression to identify, out of 153 unique variables, psychosocial variables that were predictive of sex (i.e. gender-related) in the Dutch LifeLines Cohort Study. These psychosocial variables covered gender roles and institutionalized gender. Using the estimated coefficients, gender indexes were calculated for each adult participant in the study (n = 152,728; 58.5% female; mean age 44.6 (13.1) years). We applied multiple ordinal and logistic regression to test the unique associations of the gender index and sex, and their interactions, with common somatic symptoms assessed by the SCL-90 SOM and self-reported lifetime prevalence of chronic diseases, respectively. We found that in 10.1% of the participants the gender index was not in line with participants' sex: 12.5% of men and 8.4% of women showed a discrepancy between gender index and sex. Feminine gender characteristics are associated with increased common somatic symptoms and chronic diseases, especially in men. Female sex is associated with a higher common somatic symptom burden, but not with a higher prevalence of chronic diseases. The study shows that gender and sex uniquely impact health, and should be considered in epidemiological studies. Our methodology shows that consideration of gender measures in studies is necessary and feasible, based on data generally present in cohort studies
