Biobehavioral approach to distinguishing panic symptoms from medical illness.

Panic disorder is a common psychiatric diagnosis characterized by acute, distressing somatic symptoms that mimic medically-relevant symptoms. As a result, individuals with panic disorder overutilize personal and healthcare resources in an attempt to diagnose and treat physical symptoms that are often medically benign. A biobehavioral perspective on these symptoms is needed that integrates psychological and medical knowledge to avoid costly treatments and prolonged suffering. This narrative review examines six common somatic symptoms of panic attacks (non-cardiac chest pain, palpitations, dyspnea, dizziness, abdominal distress, and paresthesia), identified in the literature as the most severe, prevalent, or critical for differential diagnosis in somatic illness, including long COVID. We review somatic illnesses that are commonly comorbid or produce panic-like symptoms, their relevant risk factors, characteristics that assist in distinguishing them from panic, and treatment approaches that are typical for these conditions. Additionally, this review discusses key factors, including cultural considerations, to assist healthcare professionals in differentiating benign from medically relevant symptoms in panic sufferers.

Determinants of adolescents' depression, anxiety, and somatic symptoms in Northwest Ethiopia: A non-recursive structural equation modeling.

In low and middle-income countries, adolescent mental health is not only a major public health challenge but also a development concern. Depression and anxiety are the most common mental health disorders and somatic symptoms often co-exist with them. Adolescents with common mental health problems are associated with an increased risk of suicide, future unemployment, and poor quality of life. However, little is known about the mental health of adolescents in Ethiopia. Thus, this study aimed to assess the determinants of depression, anxiety, and somatic symptoms among adolescents in Northwest Ethiopia, in 2022. An institution-based cross-sectional study was conducted from June 8 to 24, 2022. Two-stage stratified random sampling was used to select 1407 adolescents in Northwest Ethiopia. Structured and standardized self-administered questionnaires were used to collect the data. Non-recursive structural equation modeling was employed to assess the direct, indirect, and total effects of predictors. Adjusted regression coefficients and corresponding 95% confidence intervals were used to interpret the strength of the association. The prevalence of depression, anxiety, and somatic symptoms were 28.21% (95% CI: 25.8, 31%), 25.05% (95%CI: 22.8, 27.5), and 25.24(95% CI: 23, 27.6%) respectively. Alcohol use had a significant positive effect on depression [β = 0.14, 95% CI: 0.073, 0.201], anxiety [β = 0.11, 95% CI: 0.041, 0.188], and somatic symptoms [β = 0.12, 95% CI: 0.062, 0.211]. Stress had a significant positive effect on depression [β = 0.76, 95% CI: 0.642, 0.900], anxiety [β = 1.10, 95% CI: 0.955, 1.264], and somatic symptoms [β = 086, 95% C: 0.700, 1.025]. Depression had a direct positive effect on anxiety [β = 0.74, 95% CI: 0.508, 1.010]. In this study, the prevalence of depression, anxiety, and somatic symptoms was moderate. Alcohol use and stress were significantly related to depression, anxiety, and somatic symptoms. The bidirectional relationship between anxiety and depression was significant. Therefore, public health interventions should focus on the bidirectional relationship between depression and anxiety, as well as on identified factors to reduce the burden of mental illness in adolescents.

Needs assessment study for management of menopause in the community.

To study the symptoms of menopause and perception of women in relation to menopause in order to understand their needs. A cross-sectional, multi-centric study was undertaken at three institutions (called DH, SJ, and SK) at two cities in India. The study population comprised women between the ages of 40 and 60. Institutional Ethics Committee approval and consent of participants were ensured. Two instruments, a pilot-tested, peer-reviewed, validated, structured questionnaire and the Menopause Rating Scale (MRS) were utilized for the study. The minimum sample size was calculated to be 385 per site. Statistical analysis was conducted using the IBM Statistical Package for Social Sciences. A total of 1297 forms were analyzed. MRS scores showed psychological symptoms to be most prevalent. Joint and muscular pains were the most common somatic symptoms. Hot flashes and urogenital symptoms were experienced by a lower number. Our MRS scores were significantly higher than those seen in other regions. Urban women, site SJ, those with irregular menstrual cycles, and lower incomes scored higher than their counterparts. Awareness about menopause was patchy, especially regarding medication or support services available. The high MRS scores emphasize the need to institute awareness programs, providing information on choices available for care (hormone replacement therapy, medications, or counseling) and information on where to access services. Primary care physicians can play a vital role in fulfilling this need by ensuring timely knowledge to the community, providing correct diagnosis and treatment. This will help improve the quality of life and sense of well-being of this community.

Psychosomatic health status and corresponding comorbid network analysis of college students in traditional Chinese medicine schools.

Depression, anxiety, and somatic symptoms are highly comorbid and represent the most prevalent psychosomatic health issues. Few studies have investigated the network structure of psychosomatic symptoms among traditional Chinese medicine (TCM) students. This study aims to investigate the psychosomatic health status of college students in TCM universities, while simultaneously constructing a network structure of common somatic symptoms and psychological symptoms. Online investigation was conducted among 665 students from a university of Chinese medicine. Health Status Questionnaire, Generalized Anxiety Disorder-7 (GAD-7), and Patient Health Questionnaire-2 (PHQ-2) were used to assess the mental symptoms and physical status of participants. With the R software processing, a network model of psychosomatic symptoms was constructed. Specifically, we computed the predictability (PRE), expected influence (EI), and bridging expected influence (BEI) of each symptom. Meanwhile, the stability and accuracy of the network were evaluated using the case-deletion bootstrap method. Among the participants, 277 (41.65%) subjects exhibited depressive symptoms, and 244 (36.69%) subjects showed symptoms of anxiety. Common somatic symptoms included fatigue, forgetfulness, sighing, thirst, and sweating. Within the psychosomatic symptoms network, " worrying too much about things ", "uncontrollable worries" and "weakness" exhibited the high EI and PRE, suggesting they are central symptoms. " Little interest or pleasure in doing things," " feeling down, depressed, or hopeless," " dyssomnia," and "sighing" with high BEI values demonstrated that they are bridging symptoms in the comorbid network. The psychosomatic health status of college students in traditional Chinese medicine schools is concerning, showing high tendencies for depression, anxiety, and somatic symptoms. There exists a complex relationship between somatic symptoms and psychological symptoms among students. " Worrying too much about things ", "uncontrollable worries" and "weakness" enable to serve as comorbid intervention targets for anxiety, depression, and somatic symptoms. Addressing " little interest or pleasure in doing things," " feeling down, depressed, or hopeless," " dyssomnia," and "sighing" may effectively prevent the mutual transmission between psychological and physical symptoms. The network model highlighting the potential targeting symptoms to intervene in the treatment of psychosomatic health.

Somatic Symptoms in Major Depressive Disorder: A Cross-sectional Study in a Mental Health Setting, Vietnam

Major depressive disorder (MDD) presents a diverse clinical picture, especially with somatic symptoms, which can lead to negative impacts on the course and prognosis of the illness. This study aimed to (1) assess the prevalence of various somatic symptoms in MDD patients and (2) assess their association with demographic factors. A total of 345 outpatients diagnosed with MDD according to DSM-5 criteria were enrolled in this cross-sectional study over 6 months. Participants completed a questionnaire that included clinical and demographic information as well as the PHQ-9. There were 99.7% of patients who had at least one somatic symptom. The common somatic symptoms were fatigue (89.9%), insomnia (87.8%), palpitations (77.7%), headache (69.6%) and dizziness (61.4%). Total PHQ-9 scores and total number of somatic symptoms were found to have a regression relationship with a regression coefficient of 0.14 (t = 6.001, p < 0.001). In multiple logistic regression analysis, female gender was found to be associated with dizziness (odd ratios [OR] = 2.54, 95% confidence interval [CI] 1.53-4.21, p < 0.01), headaches (OR = 1.94, 95% CI 1.16-3.32, p < 0.05), and bowel problems (OR = 0.59, 95% CI 0.37-0.96, p < 0.05); while headaches (OR = 1.73, 95% CI 1.05-2.85, p < 0.05), and stomach problems (OR = 0.56, 95% CI 0.36-0.88, p < 0.05) were associated with age 40 and below. The study findings provide a resource for clinicians in mental health settings as well as primary care clinics in detecting inexplicable somatic symptoms associated with MDD.

Prevalence of premenstrual syndrome among students – Stress a potential risk factor

BackgroundPremenstrual syndrome (PMS) is a group of symptoms that occur prior to menstruation and disappear with its onset. This study aims to determine the prevalence and possible risk factors of PMS among the medical students. MethodsWe conducted a cross sectional survey which includes 450 female health professional undergraduate and postgraduate students between the age group of 18–35years. A self-administered questionnaire for PMS and self-rating stress (perceived stress scale-PSS) was used to evaluate the prevalence and severity of the PMS. ResultsThe prevalence of PMS among the student was 76.35%. Prevalence of PMS was significantly higher among the participants of age group 18–21 years, hostellers, participants who reported irregular physical activity and participants with high stress levels. The most common psychological symptom of PMS reported was reduced social interaction, followed by irritability while the most common somatic symptoms were aches and pains - muscle pain followed by abdominal bloating. PSS levels were significantly higher in females with PMS as compared to females without PMS. ConclusionThis study suggests that stress is a potential risk factor in increasing the incidence of PMS among young girls. PMS can impact the academic performance and decrease quality of life of students. Thus, interventions such as yoga and mind relaxing techniques should be adopted to minimize stress levels and thus improve the quality of life among young females who experience PMS.

Navigating Life With HIV as an Older Adult on the Kenyan Coast: Perceived Health Challenges Seen Through the Biopsychosocial Model.

Objectives: This study explores the perceptions of adults living with HIV aged ≥50years (recognized as older adults living with HIV-OALWH), primary caregivers and healthcare providers on the health challenges of ageing with HIV at Kilifi, a low literacy setting on the coast of Kenya. Methods: We utilized the biopsychosocial model to explore views from 34 OALWH and 22 stakeholders on the physical, mental, and psychosocial health challenges of ageing with HIV in Kilifi in 2019. Data were drawn from semi-structured in-depth interviews, which were audio-recorded and transcribed. A framework approach was used to synthesize the data. Results: Symptoms of common mental disorders, comorbidities, somatic symptoms, financial difficulties, stigma, and discrimination were viewed as common. There was also an overlap of perceived risk factors across the physical, mental, and psychosocial health domains, including family conflicts and poverty. Conclusion: OALWH at the Kenyan coast are perceived to be at risk of multiple physical, mental, and psychosocial challenges. Future research should quantify the burden of these challenges and examine the resources available to these adults.

Couvade Syndrome among partners of women with physiological and complicated pregnancy

Abstract Aim. To assess the prevalence of couvade syndrome and analyze the factors determining the occurrence of this syndrome in the partners of pregnant women. Material and method. The research material was collected by a diagnostic survey, using an author’s survey questionnaire. Results. Couvade Syndrome occurs in 94.3% of partners of women with complicated pregnancies. Among the most common somatic symptoms there are: back pain (56.2%), headaches (53.3%), appetite changes (48.6%), indigestion (34.3%) and abdominal pain of unknown origin (31.4%), while mental ones include: sleep disturbances (37.1%), irritability (34.3%), tension (32.4%), regardless of the course of partner’s pregnancy. Men, who were married, were more likely to have Couvade symptoms than those in an informal relationship, regardless of the course of partner’s pregnancy (p=0.02). Respondents without Couvade Syndrome were more likely to have low levels of involvement in their partner’s current pregnancy than those with symptoms, regardless of the course of this pregnancy (p=0.03). Men with symptoms of the syndrome were more likely to be less involved in their responsibilities at work than those without symptoms, regardless of the course of partner’s pregnancy (p=0.0006). Conclusions. The majority (94.3%) of partners of women with complicated pregnancies have a Couvade Syndrome. The most common somatic symptoms include back pain, headaches, appetite changes, indigestion and abdominal pain of unknown origin, while the mental ones: sleep disturbances, irritability, tension, anxiety and nervousness. Married men are more likely to have Couvade Syndrome than those in an informal relationship. Low levels of involvement in the current pregnancy are shown by men who do not have the syndrome. Men, who have the Couvade Syndrome, are less involved in their work responsibilities.

Sex and gender differences in primary care help-seeking for common somatic symptoms: a longitudinal study

Objective Women are reported to consult general practitioners (GPs) more frequently than men. However, previous studies on sex differences in help-seeking behavior for somatic symptoms do not distinguish between sex and gender, do not account for sex differences in presented symptoms, and are frequently conducted in clinical settings, automatically excluding non-help seekers. Therefore, we aim to assess the independent associations of sex and gender with primary care help-seeking for somatic symptoms in the general population. Design and setting Records from the longitudinal population-based Lifelines Cohort Study were linked to routine electronic health records from GPs. Subjects Participants reporting new-onset common somatic symptoms. Main outcome measures Associations between sex and gender, operationalized via a novel gender-index, with primary care help-seeking for somatic symptoms and differences in the strength of the association between gender and help-seeking for somatic symptoms between women and men. Results Of 20,187 individuals with linked data, 8325 participants (67.5% female; mean age = 44.5 years [SD = 12.9]) reported at least one new-onset somatic symptom. Hereof, 255 (3.1%) consulted the GP within 6 weeks of symptom onset. Female sex was positively associated with consulting the GP (OR = 1.78; 95%CI = 1.13–2.80), whereas feminine gender was not (OR = 0.67; 95%CI = 0.39–1.16). The latter association did not differ in strength between men and women. More paid working days are negatively associated with help-seeking (OR = 0.95; 95%CI = 0.91–0.98). Conclusions The results suggest that female sex rather than feminine gender is associated with primary care help-seeking behavior for somatic symptoms. Nevertheless, clinicians should be aware that gender-related variables, such as mean paid working days, may be associated with help-seeking behavior.

A Training Programme for Developing Social and Personal Resources and Its Effects on the Perceived Stress Level in Adults in Daily Life—Study Protocol for a Prospective Cohort Study

Persistent stress and insufficient coping strategies have negative consequences for physical and mental health. Teaching adults the skills needed to sustainably improve stress-buffering aspects of their character could contribute to the prevention of stress-related diseases. In this non-randomised, observational, prospective cohort study, participants of a training programme for developing social and personal skills, to which they previously self-assigned, are assessed. The 12-month training programme focuses on improving perceived stress level (primary outcome), health behaviour, presence of common somatic symptoms, satisfaction with life, quality of social relationships, and wellbeing by addressing life goals, meaning in life, sense of coherence, social and personal resources, and transcendence. Study participants are recruited from the training groups via the training organiser. Companions, persons with whom they share a close relationship, are recruited to assess the interpersonal diffusion effects of the training. Matched individuals not participating in the training are the control group. Parameter assessment follows a pre-, post-, and follow-up (6 months) design. Designed to improve health-related outcomes in adults by addressing personality characteristics and using Lozanov's superlearning principles to improve learning efficiency, this training programme is, to the study team's knowledge, the first of its kind. From a research perspective, the outcomes of this study can provide new insights into primary prevention of stress-related diseases and how the effects of these measures are passed on through common personal interaction. The trial has been pre-registered (registration number: NCT04165473).

Somatic symptoms and related disorders in a large cohort of people with epilepsy: A cohort study.

This study was undertaken to characterize somatic symptoms and related disorders (SSD) in epilepsy. Adults with epilepsy under active follow-up at a tertiary epilepsy center were consecutively enrolled. The diagnosis of SSD was performed by an experienced psychologist based on the structured clinical interview for Statistical Manual of Mental Disorders, 5th edition. Detailed social/demographic data, epilepsy features, psychiatric features, life quality, disability, and economic burden were collected and compared between people with SSD and those without. Bodily distress syndrome checklist, Somatic Symptom Disorder-B Criteria Scale, Patient Health Questionnaire-9, and Generalized Anxiety Disorder seven-item scale (GAD-7) were used to evaluate SSD individuals' somatic symptoms, symptom-related psychological distress, and depressive and anxious symptoms. Quality of life and disability were assessed by Quality of Life in Epilepsy Inventory 31 (QOLIE-31) and World Health Organization Disability Assessment Schedule V.2.0 (WHO DAS 2.0). A risk prediction nomogram was generated using least absolute shrinkage and selection operator (LASSO) analysis and validated. One hundred fifty of 631 participants (24%) were diagnosed with SSD. In people with SSD, the top three most common somatic symptoms were memory impairment, headache, and dizziness (85%, 80%, and 78%, respectively), and multiple systems were involved in most (82%) people with SSD. Compared with people without SSD, those with SSD had lower QOLIE-31 total scores, and higher WHO DAS 2.0 scores and disease economic burdens. LASSO analysis suggested that a history of severe traumatic brain injury, hippocampal sclerosis, low seizure worry and medication effects scores on QOLIE-31, multiple systems affected by somatic symptoms, and a high GAD-7 score were risk factors of SSD. The nomogram was validated for good accuracy in the training and testing cohorts. SSD are likely to be a common comorbidity in epilepsy and harm epilepsy prognosis. Our risk prediction nomogram was successfully developed but needs further validation in larger cohorts.

The Common Neural Mechanism of Somatic Symptoms of Depression and Anxiety Disorders: A Resting-State Functional Magnetic Resonance Imaging Study

Introduction: Somatic symptoms often occur as a manifestation of depression and anxiety. The subgenual anterior cingulate cortex (sgACC) has been shown to be closely related to both depression and anxiety and plays an important role in somatic symptoms. However, little is known regarding whether the abnormal function of the sgACC contributes to the common somatic symptoms of depression and anxiety. Methods: Resting-state functional connectivity (RSFC) analysis based on the seed of the sgACC was investigated in 23 major depressive disorder (MDD) patients with somatic symptoms, 20 generalized anxiety disorder (GAD) patients with somatic symptoms, and 22 demographically matched healthy controls (HCs). The severity of depression, anxiety, and somatic symptoms was assessed using the Hamilton Depression Rating Scale (HAMD), Hamilton Anxiety Rating Scale (HAMA), and the 15-item somatic symptom severity scale from the Patient Health Questionnaire (PHQ-15), respectively. An analysis of covariance analysis (ANCOVA) was conducted to determine RSFC alterations among GAD, MDD, and HC groups with age, gender, and head motion as covariates. Correlation analyses were conducted between the RSFC of the sgACC and PHQ-15. Results: The significantly different RSFC of right sgACC among the three groups was found in right STG, left cerebellum, and right postcentral. Post hoc analysis indicated that both MDD and GAD patients showed a decreased RSFC between the right sgACC and right STG than HCs, and both were negatively correlated with the PHQ-15 scores. Conclusion: The abnormally decreased RSFC of the sgACC and STG may be the underlying common mechanisms of depression and anxiety combined with somatic symptoms.

Physicians' and Patients' Interruptions in Clinical Practice: A Quantitative Analysis.

Physicians' interruptions have long been considered intrusive, masculine actions that inhibit patient participation, but a systematic analysis of interruptions in clinical interaction is lacking. This study aimed to examine when and how primary care physicians and patients interrupt each other during consultations. We coded and quantitatively analyzed interruption type (cooperative vs intrusive) in 84 natural interactions between 17 primary care physicians and 84 patients with common somatic symptoms. Data were analyzed using a mixed-effects logistic regression model, with role, gender, and consultation phase as predictors. Of the 2,405 interruptions observed, 82.9% were cooperative. Among physicians, men were more likely to make an intrusive interruption than women (β = 0.43; SE, 0.21; odds ratio [OR] = 1.54; 95% CI, 1.03-2.31), whereas among patients, men were less likely to make an intrusive interruption than women (β = -0.35; SE, 0.17; OR = 0.70; 95% CI, 0.50-0.98). Patients' interruptions were more likely to be intrusive than physicians' interruptions in the phase of problem presentation (β = 0.71; SE, 0.23; OR = 2.03; 95% CI, 1.30-3.20), but not in the phase of diagnosis and/or treatment plan discussion (β = -0.17; SE, 0.15; OR = 0.85; 95% CI, 0.63-1.15). Most interruptions in clinical interaction are cooperative and may enhance the interaction. The nature of physicians' and patients' interruptions is the result of an interplay between role, gender, and consultation phase.

Disrupted Cerebellar-Default Mode Network Functional Connectivity in Major Depressive Disorder With Gastrointestinal Symptoms.

Gastrointestinal (GI) symptoms are one of the common somatic symptoms presented in patients with major depressive disorder (MDD). Higher frequency of GI symptoms and higher GI symptom burden were linked to greater depression severity and increased risk of suicide ideation. However, few studies have explored the underlying mechanisms of GI symptoms in MDD. Based on previous studies, the cerebellar-DMN circuits may play a potentially critical role in GI symptoms comorbid with depression. Fifty-two first-episode drug-naive patients with MDD (35 with GI symptoms and 17 without GI symptoms) and 28 matched healthy controls were recruited in the current study and underwent resting-state functional magnetic resonance imaging scan. Cerebellar seed-based functional connectivity maps were established. Relative to depressed patients without GI symptoms, significantly increased cerebellar-anterior default mode network (DMN) connectivities were found in those with GI symptoms. Both increased and decreased functional connectivities were found between cerebellum and posterior DMN in patients with GI symptoms compared with those without GI symptoms and healthy controls. Moreover, the right Crus I - right superior temporal gyrus connectivity value was related to severity of GI symptoms and depression in all patients with MDD. The support vector machine analysis demonstrated a satisfactory classification accuracy (89%) of the disrupted cerebellar-DMN connectivities for correctly identifying MDD patients with GI symptoms. These results revealed the possible neural mechanisms for the involvement of cerebellar-DMN circuits in GI symptoms co-occurred with MDD.

Differences Between Women and Men Are Present in the Rate of Diagnosed Diseases After a Diagnostic Intervention is Conducted in Primary Care.

Recently it was shown that the relative lack of diagnostic interventions conducted in women mediated the negative association between female sex and diagnosed disease. However, it remains unknown whether women and men receive disease diagnoses in an equal frequency after diagnostic interventions have been performed in general practice. We used generalized linear mixed-effect models to assess the association between diagnostic interventions and disease diagnoses when patients presented with common somatic symptoms and studied whether the association differed between female and male patients. RESULTS: In 34,268 episodes of care (61.4% female) physical examinations and specialist referrals were associated with more disease diagnoses (OR = 2.32; 95% CI = 2.17-2.49 and OR = 1.38; 95% CI = 1.27-1.49, respectively), whereas laboratory diagnostics were associated with fewer disease diagnoses (OR = 0.50; 95% CI = 0.47-0.54). Significant interaction terms showed that women presenting with back pain, tiredness, arm and/or leg symptoms and tingling extremities were provided with fewer disease diagnoses after diagnostic interventions were performed than men. We found no significant interaction term that indicated that men were provided with fewer disease diagnoses after a diagnostic intervention than women. CONCLUSION: Especially when patients present with the mentioned symptoms, general practitioners should be aware that diagnostic interventions yield fewer disease diagnoses in female patients than in men. Yet, performing fewer diagnostic interventions in women with these symptoms will further exacerbate sex differences in disease diagnoses.

Shared and Distinct Fractional Amplitude of Low-Frequency Fluctuation Patterns in Major Depressive Disorders With and Without Gastrointestinal Symptoms.

Objective: Gastrointestinal (GI) symptoms are fairly common somatic symptoms in depressed patients. The purpose of this study was to explore the influence of concomitant GI symptoms on the fractional amplitude of low-frequency fluctuation (fALFF) patterns in patients with major depressive disorder (MDD) and investigate the connection between aberrant fALFF and clinical characteristics.Methods: This study included 35 MDD patients with GI symptoms (GI-MDD patients), 17 MDD patients without GI symptoms (nGI-MDD patients), and 28 healthy controls (HCs). The fALFF method was used to analyze the resting-state functional magnetic resonance imaging data. Correlation analysis and pattern classification were employed to investigate the relationship of the fALFF patterns with the clinical characteristics of patients.Results: GI-MDD patients exhibited higher scores in the HRSD-17 and suffered more severe insomnia, anxiety/somatization, and weight loss than nGI-MDD patients. GI-MDD patients showed higher fALFF in the right superior frontal gyrus (SFG)/middle frontal gyrus (MFG) and lower fALFF in the left superior medial prefrontal cortex (MPFC) compared with nGI-MDD patients. A combination of the fALFF values of these two clusters could be applied to discriminate GI-MDD patients from nGI-MDD patients, with accuracy, sensitivity, and specificity of 86.54, 94.29, and 70.59%, respectively.Conclusion: GI-MDD patients showed more severe depressive symptoms. Increased fALFF in the right SFG/MFG and decreased fALFF in the left superior MPFC might be distinctive neurobiological features of MDD patients with GI symptoms.

Somatic symptoms in sleep disturbance

ABSTRACT Despite sleep disturbance and somatic symptoms being common health complaints, the relationship between these disturbances and single somatic symptoms is not well documented. The objectives of this study were to (i) identify somatic symptoms that are particularly associated with sleep disturbance, here referred to as somatic symptoms related to sleep disturbance (SS-SD), (ii) determine increased risk of sleep disturbance for each SS-SD and for a certain number of SS-SD, with and without controlling for anxiety and depression, and (iii) determine sensitivity and specificity for identifying sleep disturbance based on number of SS-SD in a general Swedish sample. Population-based, cross-sectional data based on validated questionnaire instruments were used from participants who constituted a sleep disturbance (n = 864) or a reference (n = 2340) group. Among 15 common somatic symptoms, stomach pain, back pain nausea/gas/indigestion, dizziness, and constipation/loose bowels/diarrhea were identified as SS-SD, with odds ratios of increased risk of sleep disturbance that ranged from 1.93 to 2.44 (1.36–1.79 and 1.54–1.91 when controlled for anxiety and depression, respectively). The risk of sleep disturbance increased by 1.44 times for each SS-SD (1.25 and 1.30 when controlled for anxiety and depression, respectively). A cutoff of two/three or more SS-SD had a sensitivity of 72.5/54.2% and a specificity of 50.0/69.7% for identifying sleep disturbances. When patients present with these somatic symptoms with or without a pathophysiological explanation, primary care clinicians may consider screening for sleep disturbance.

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

ObjectiveLittle 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. MethodsIn 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. ResultsWomen 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. ConclusionThis 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.

The association of sex, age and FKBP5 genotype with common somatic symptoms: A replication study in the lifelines cohort study

ObjectiveOur aim was to replicate a recent study that reported an association between the rs9470080 CC-genotype and common somatic symptoms in women, but not in men. Additionally, we quantified the genetic contribution to phenotypic variation in common somatic symptom levels. MethodsWe used data from the Lifelines Cohort Study, including 28,299 participants (60.0% female; 44.2% CC-genotype; mean age 42.9 (14.2) years). Common somatic symptoms were measured with the SCL-90 SOM subscale. To assess the association between the rs9470080 genotype and SCL-90 SOM scores we applied similar analyses as the original study, including independent t-tests, two-way ANOVAs and a mixed ANOVA. To estimate the proportion of phenotypic variance in SCL-90 SOM scores explained by single nucleotide polymorphisms (SNPs), we used a genomic-relatedness-based restricted maximum-likelihood method. ResultsWe could not replicate the original study's findings. We found no association between the rs9470080 genotype and common somatic symptom levels in either female or male participants (F(1, 8775) = 1.07, p = 0.30 and F(1,13,903) = 0.01, p = 0.93, respectively). Genome-wide heritability analyses show that 12.1% (p = 2.1e-08) of the phenotypic variance in common somatic symptom levels in Lifelines can be explained by SNPs. The genetic contribution to common somatic symptom levels was higher in male participants (SNP-h2 = 20.5%; p = 9.1e-08) than in female participants (SNP-h2 = 12.0%, p = 2.8e-05). ConclusionOur findings of significant SNP-h2 and the sex-specific differences herein, does warrant further sex-stratified research of individual genetic variants associated with common somatic symptoms. Preferably, further research should be performed within the analytic framework of a genome-wide association study.
