Prevalence of functional gastrointestinal disorders in women who report domestic violence to the police

Gastrointestinal symptoms in abused nonpatient women

BACKGROUND

Severely abused nonpatient women report a high number of gastrointestinal (GI) symptoms and GI syndromes. Little is known about whether the abuse‒symptom relationship varies across different life, social, and community conditions.

OBJECTIVE

To comparatively assess the timing, type and severity of physical and/or sexual abuse and GI symptoms of nonpatient women who contacted a lawyer for legal support with those who sought shelter in antiviolence centers.

SUBJECTS AND METHODS

Forty-six lawyer controls (LCs) (aged 29-80 years) and 67 women (aged 18-58 years) sheltered in antiviolence (V) centers completed an identical anonymous questionnaire with medical and abuse sections. The severity of abuse was assessed with the 0-6 Abuse Severity Measure (ASM). The associations between abuse characteristics and the number of symptoms were assessed with the Poisson regression model.

RESULTS

Among the LC women, 65% experienced physical and/or sexual abuse in childhood and/or adulthood, whereas 100% of the V women did. In both groups, most women experienced combined sexual and physical abuse in childhood and adulthood. The ASM was < 2 in 57% of the LC and 18% of the V women. LC and V women reported an average of 4.9 and 4.6 GI symptoms, respectively. In both groups, women who had been both sexually and physically abused reported a greater number of GI symptoms. Childhood and adulthood abuse were associated with more GI symptoms only in V women. LC women with ASM > 2 reported more GI symptoms than those with an ASM of < 2 (median; IQR: 6.5; 3-11 vs 3; 1-7, p = 0.002). V women with ASM > 5 reported significantly more GI symptoms than control women with ASM < 5 (median; IQR: 6; 4-8 vs 4.5; 2-8, p < 0.001).

CONCLUSIONS

In abused "nonpatient" women, the combination of physical and sexual abuse, childhood and adulthood abuse and higher severity scores were associated with a greater number of GI symptoms, irrespective of the social and economic setting.

The Impact of Psychotrauma and Emotional Stress Vulnerability on Physical and Mental Functioning of Patients with Inflammatory Bowel Disease

Inflammatory bowel disease (IBD) is a chronic health condition thought to be influenced by personal life experiences and emotional stress sensitivity (neuroticism). In the present study, we examined the impact of cumulative trauma experiences and trait neuroticism (as a measure for emotional stress vulnerability) on physical and mental functioning of n = 211 patients diagnosed with IBD (112 Crohn's disease, 99 ulcerative colitis). All patients were assessed for self-reported trauma histories, emotional stress vulnerability, clinical disease activity, functional gastrointestinal (GI) symptoms, and quality of life. Results showed that patients with severe IBD activity have endured significantly more interpersonal trauma and victimization than those with quiescent IBD. Moreover, cumulative trauma was found to exert an indirect (neuroticism-mediated) effect on patients' symptom complexity, with trauma and neuroticism conjointly explaining 16-21% of the variance in gastrointestinal and 35% of the variance in mental symptoms. Upon correction for condition (using a small group of available controls, n = 51), the predictive capacity of trauma and neuroticism increased further, with both predictors now explaining 31% of the somatic-and almost 50% of the mental symptom heterogeneity. In terms of trauma type, victimization (domestic violence and intimate abuse) proved the best predictor of cross-sample symptom variability and the only trauma profile with a consistent direct and indirect (neuroticism-mediated) effect on patients' mental (QoL) and physical fitness. Results are consistent with the growing body of evidence linking experiential vulnerability factors (trauma and neuroticism) and associated feelings of personal ineffectiveness, helplessness, and uncontrollability to interindividual differences in (GI) disease activity and quality of life.

The association between exposure to domestic abuse in women and the development of syndromes indicating central nervous system sensitization: A retrospective cohort study using UK primary care records

BACKGROUND

Domestic abuse is a global public health issue. The association between the development of central sensitivity syndromes (CSS) and previous exposure to domestic abuse has been poorly understood particularly within European populations.

METHODS

A retrospective cohort study using the 'The Health Improvement Network,' (UK primary care medical records) between 1st January 1995-31st December 2018. 22,604 adult women exposed to domestic abuse were age matched to 44,671 unexposed women. The average age at cohort entry was 36 years and the median follow-up was 2.5 years. The outcomes of interest were the development of a variety of syndromes which demonstrate central nervous system sensitization. Fibromyalgia, chronic fatigue syndrome and temporomandibular joint disorder outcomes have been reported previously. Outcomes were adjusted for the presence of mental ill health.

RESULTS

During the study period, women exposed to domestic abuse experienced an increased risk of developing chronic lower back pain (adjusted incidence rate ratio [aIRR] 2.28; 95% CI 1.85-2.80), chronic headaches (aIRR 3.15; 95% CI 1.07-9.23), irritable bowel syndrome (aIRR 1.41; 95% CI 1.25-1.60) and restless legs syndrome (aIRR 1.89; 95% CI 1.44-2.48). However, no positive association was seen with the development of interstitial cystitis (aIRR 0.52; 95% CI 0.14-1.93), vulvodynia (aIRR 0.42; 95% CI 0.14-1.25) and myofascial pain syndrome (aIRR 1.01; 95% CI 0.28-3.61).

CONCLUSION

This study demonstrates the need to consider a past history of domestic abuse in patients presenting with CSS; and also consider preventative approaches in mitigating the risk of developing CSS following exposure to domestic abuse.

SIGNIFICANCE

Domestic abuse is a global public health issue, with a poorly understood relationship with the development of complex pain syndromes. Using a large UK primary care database, we were able to conduct the first global cohort study to explore this further. We found a strong pain morbidity burden associated with domestic abuse, suggesting the need for urgent public health intervention to not only prevent domestic abuse but also the associated negative pain consequences.

Tangible pathologies in functional dyspepsia

Functional dyspepsia (FD) is a common, costly and complex disease, currently defined by symptoms, directed by the Rome consensus on functional bowel disorders, which has evolved over the past two decades. Symptoms include abdominal pain, are often meal related and there are two major subtypes, postprandial distress syndrome and epigastric pain syndrome, not attributed to pathology. Increasingly it is recognised that tangible pathologies occur in FD, for example Helicobacter pylori and other pathophysiological changes, most notably duodenal pathology, namely duodenal eosinophilia, permeability alterations, structural neuronal changes and microbial duodenal dysbiosis. This has led to the idea that FD is a true disease entity and triggers of this condition based on epidemiology studies point towards allergy, immune disorders and infection. Anxiety and depression may precede or follow FD, (brain-gut/gut-brain disorders). Currently most therapies for FD are inadequate but underlying pathology may lead to targeted treatment success as an attainable goal.

Digital Education of Health Professionals on the Management of Domestic Violence: Systematic Review and Meta-Analysis by the Digital Health Education Collaboration

Background

The World Health Organization states that 35% of women experience domestic violence at least once during their lifetimes. However, approximately 80% of health professionals have never received any training on management of this major public health concern.

Objective

The objective of this study was to evaluate the effectiveness of health professions digital education on domestic violence compared to that of traditional ways or no intervention.

Methods

Seven electronic databases were searched for randomized controlled trials from January 1990 to August 2017. The Cochrane Handbook guideline was followed, and studies reporting the use of digital education interventions to educate health professionals on domestic violence management were included.

Results

Six studies with 631 participants met our inclusion criteria. Meta-analysis of 5 studies showed that as compared to control conditions, digital education may improve knowledge (510 participants and 5 studies; standardized mean difference [SMD] 0.67, 95% CI 0.38-0.95; I²=59%; low certainty evidence), attitudes (339 participants and 3 studies; SMD 0.67, 95% CI 0.25-1.09; I²=68%; low certainty evidence), and self-efficacy (174 participants and 3 studies; SMD 0.47, 95% CI 0.16-0.77; I²=0%; moderate certainty evidence).

Conclusions

Evidence of the effectiveness of digital education on health professionals’ understanding of domestic violence is promising. However, the certainty of the evidence is predominantly low and merits further research. Given the opportunity of scaled transformative digital education, both further research and implementation within an evaluative context should be prioritized.

Irritable bowel syndrome diagnosis and management: A simplified algorithm for clinical practice

BACKGROUND

Effective management of irritable bowel syndrome (IBS), a common functional gastrointestinal disorder, can be challenging for physicians because of the lack of simple diagnostic tests and the wide variety of treatment approaches available.

OBJECTIVE

The objective of this article is to outline a simple algorithm for day-to-day clinical practice to help physicians navigate key stages to reaching a positive IBS diagnosis and guidance on how to prioritise the use of specific management strategies.

METHODS

This algorithm was based on the opinion of an expert panel evaluating current evidence.

RESULTS

The key principles forming the foundation of this evidence-supported algorithm are: confidently naming and explaining an IBS diagnosis for the patient, followed by assessment of key patient characteristics likely to influence the choice of therapy, such as predominant symptoms, and exploring the patient agenda and preferences. Consultation should always include education and reassurance with an explanatory model of IBS tailored to the patient. Individualised lifestyle changes, dietary modifications, pharmacological therapies, psychological strategies or a combination of interventions may be used to optimise treatment for each patient.

CONCLUSION

The simple visual tools developed here navigate the key stages to reaching a positive diagnosis of IBS, and provide a stepwise approach to patient-centred management targeted towards the most bothersome symptoms. Establishing a strong patient-physician relationship is central to all stages of the patient journey from diagnosis to effective management.

Irritable bowel syndrome (IBS) subtypes: Nothing resembles less an IBS than another IBS

Two new members of "IBS Patient Association" met at a meeting. Feeling somewhat lost, not knowing anybody present, they introduced themselves to each other. After exchanging names, one asks the other - "What's your problem?" The other one answers - "I got constipation that laxatives fail to relieve, and my belly, which is always bloated, sometimes hurts so much that I can´t even leave home". Deeply surprised, the first individual inquires - "What are you doing here then?" "Why, I came to this meeting looking for some help for my irritable colon", she answered. "Irritable colon? That's no irritable colon. Irritable bowel syndrome is what I suffer from, and it's diarrhea that won't let me be; can't stop running to the toilet, and cramps just pop up any time". Now both looked surprised. Both thought they had come to the wrong meeting, and both were on the verge of leaving. Luckily, the Association's secretary showed up and explained that both had IBS.

Altered Eating Behaviors in Female Victims of Intimate Partner Violence

Little is known about altered eating behaviors that are associated with the experience of intimate partner violence (IPV) victimization. Our aim was to explore the experiences and perspectives of IPV victims regarding their eating behaviors and their attitudes toward and use of food. We conducted focus groups and individual interviews with 25 IPV victims identified at a domestic violence agency and asked them about their eating behaviors and how, if at all, these behaviors related to their experience of IPV. Qualitative analysis of the transcribed encounters identified themes explicating the relationship between their eating behaviors and experiences of IPV. All women described altered eating behaviors related to IPV that were categorized into several major themes: (a) somatization (victims experience significant somatic symptoms as a result of abuse); (b) avoiding abuse (victims modify their eating behaviors to avoid abuse); (c) coping (victims use food to handle the psychological effects of abuse); (d) self-harm (victims use food to hurt themselves as a reaction to the abuse); and (e) challenging abusive partners (victims use their eating behaviors to retaliate against their abusers). IPV can provoke altered eating behaviors in victims that may be harmful, comforting, or a source of strength in their abusive relationships. Understanding the complex relationship between IPV and victims' altered eating behaviors is important in promoting healthy eating among victims.

High prevalence of symptoms in a severely abused "non-patient" women population

OBJECTIVE

The objective of this article is to assess the prevalence of somatic symptoms and of gastrointestinal (GI) syndromes in abused "non-patient" women and the association with the time of perpetration, type, and severity of abuse.

METHODS

Sixty-seven women, 18-58 years, receiving shelter in anti-violence associations were invited to fill out an anonymous questionnaire with a medical and an abuse section. The severity of abuse was expressed as the 0-6 Abuse Severity Measure (ASM). The association between abuse characteristics and the number of symptoms, and GI syndromes was assessed by Poisson regression model.

RESULTS

Most women suffered from childhood and adulthood sexual and physical abuse. They reported a mean of 5.1 GI symptoms (range 0-13; median 5; IQR 6) and of 1.3 extra-GI symptoms (range 0-6; median 1; IQR 2); 30% of women matched the Rome II Criteria for one, 36% for two, and 4.4% for three or more syndromes, respectively. Women with an ASM of 5-6, having suffered from both sexual and physical abuse, reported significantly (p = 0.02) more GI symptoms, but not extra-GI ones (p = 0.07), and met criteria for more GI syndromes than women with an ASM ≤4 and those reporting only one type of abuse. No association was found between the time of perpetration of the abuse and the number of GI and extra-GI symptoms.

CONCLUSIONS

Symptoms in abused "non-patient" women mainly concern the abdomen and the GI tract. A history of severe, combined physical and sexual abuse is associated with a higher number of GI symptoms.

The role of psychosocial factors and psychiatric disorders in functional dyspepsia

In this Review, after a brief historical introduction, we first provide an overview of epidemiological studies that demonstrate an association between functional dyspepsia and psychological traits, states or psychiatric disorders. These studies suggest an important intrinsic role for psychosocial factors and psychiatric disorders, especially anxiety and depression, in the aetiopathogenesis of functional dyspepsia, in addition to their putative influence on health-care-seeking behaviour. Second, we describe pathophysiological evidence on how psychosocial factors and psychiatric disorders might exert their role in functional dyspepsia. Novel insights from functional brain imaging studies regarding the integration of gut-brain signals, processed in homeostatic-interoceptive brain regions, with input from the exteroceptive system, the reward system and affective and cognitive circuits, help to clarify the important role of psychological processes and psychiatric morbidity. We therefore propose an integrated model of functional dyspepsia as a disorder of gut-brain signalling, supporting a biopsychosocial approach to the diagnosis and management of this disorder.

Physiologic changes associated with violence and abuse exposure: an examination of related medical conditions

Although the extant evidence is replete with data supporting linkages between exposure to violence or abuse and the subsequent development of medical illnesses, the underlying mechanisms of these relationships are poorly defined and understood. Physiologic changes occurring in violence- or abuse-exposed individuals point to potentially common biological pathways connecting traumatic exposures with medical outcomes. Herein, the evidence describing the long-term physiologic changes in abuse- and violence-exposed populations and associated medical illnesses are reviewed. Current data support that (a) specific neurobiochemical changes are associated with exposure to violence and abuse; (b) several biological pathways have the potential to lead to the development of future illness; and (c) common physiologic mechanisms may moderate the severity, phenomenology, or clinical course of medical illnesses in individuals with histories of exposure to violence or abuse. Importantly, additional work is needed to advance our emerging understanding of the biological mechanisms connecting exposure to violence and abuse and negative health outcomes.

Systematic review and meta-analysis of the prevalence of irritable bowel syndrome in individuals with dyspepsia

BACKGROUND & AIMS

Dyspepsia and irritable bowel syndrome (IBS) are common conditions that can coexist in patients. We performed a systematic review and meta-analysis to estimate prevalence of IBS in dyspepsia.

METHODS

Relevant articles published through August 2008 were identified from MEDLINE and EMBASE literature searches (23,457 citations). Eligible studies included adults recruited from the community, the workplace, blood donation or screening clinics, and family physician offices or internal medicine clinics. Selected studies reported prevalence of dyspepsia and IBS within the same population. The prevalence of IBS in subjects with and without dyspepsia was pooled for all studies and compared. Odds ratios (OR) and confidence intervals (CI) were calculated. The degree of overlap between dyspepsia and IBS was determined.

RESULTS

Of 239 papers evaluated, 150 reported prevalence of dyspepsia and 19 (involving 18,173 subjects) reported the proportion of subjects with IBS within the same population. The prevalence of dyspepsia was 27% (95% CI, 23%-31%). The prevalence of IBS in subjects with dyspepsia was 37% (95% CI, 30%-45%) compared with 7% (95% CI, 5%-10%) in those without. The pooled OR for IBS in subjects with dyspepsia was 8 (95% CI, 5.74-11.16). The degree of overlap between the 2 conditions varied from 15% to 42%, depending on diagnostic criteria used for each.

CONCLUSIONS

Individuals with dyspepsia have an 8-fold increase in prevalence of IBS compared with the population. The strength of the association suggests common pathogenic mechanisms. Dyspeptic patients should be assessed routinely for IBS.

Irritable bowel syndrome: novel views on the epidemiology and potential risk factors

Symptoms consistent with the irritable bowel syndrome are remarkably frequent around the world. Irritable bowel syndrome prevalence ranges from 2.1% to 22%, depending on criteria used. Women are more frequently affected than men, but the reasons remain obscure; irritable bowel syndrome occurs in all age groups but there appears to be a modest decline in prevalence with advancing age again for unknown reasons. The incidence of irritable bowel syndrome per year has been estimated at approximately 1.5% in community subjects; annually only 0.2% of population will be diagnosed with irritable bowel syndrome. The natural history of irritable bowel syndrome is characterized by symptomatic flare ups and by a high rate of transition to other functional gastrointestinal diseases over the long term. Well recognized risk factors for irritable bowel syndrome include psychological distress and gastroenteritis. However, the association of psychological distress in some cases may reflect confounding factors and might be explained at least in part by cytokine production. Familial aggregation of irritable bowel syndrome occurs, and while the environment is key, twin studies generally support a genetic component in irritable bowel syndrome explaining up to 20% of the variability. Prior surgery may increase risk of irritable bowel syndrome. Early childhood trauma may be important; a low birth weight, nasogastric suction at birth, childhood abuse, and low socioeconomic status may carry an increased risk of suffering with irritable bowel syndrome as an adult. The role of diet remains uncertain but under-studied.

Update on irritable bowel syndrome and gender differences

Irritable bowel syndrome (IBS) is a chronic functional GI disorder characterized by abdominal pain associated with alterations in defecation or stool frequency and consistency. In Western industrialized countries, women seek health care services for their symptoms more frequently than men. The cause of IBS is likely multifactorial involving altered motility, visceral hypersensitivity, and dysregulation of the autonomic nervous system. Many patients note that their symptoms are exacerbated by diet and stress, and women frequently report menstrual cycle fluctuations in symptoms. Current approaches to IBS management include behavioral management therapies such as dietary intake changes and stress reduction cognitive restructuring. Drug therapies are targeted at altering pain sensitivity, motility, and secretion. This review provides an overview of the pathogenesis of IBS, factors that contribute to gender differences, and current therapeutic approaches for symptom management.

Abuse in women and men with and without functional gastrointestinal disorders

We aimed to investigate the history of abuse in childhood and adulthood and health-related quality of life (HRQL) in women and men with FGID in the general adult population. A cross-sectional study in a random population sample (n = 1,537, 20-87 years) living in Osthammar municipality, Sweden, in 1995 was performed. Persons with FGID (n = 141) and a group of abdominal symptom-free controls (SSF, n = 97) were selected by means of a validated questionnaire assessing gastrointestinal symptoms (the ASQ). Abuse, anxiety and depression (the HADS) and HRQL (the PGWB) were measured. Women with FGID had a higher risk of having a history of some kind of abuse, as compared with the SSF controls (45% vs.16%, OR = 2.0, 95% CI: 1.01-3.9; SSF = 1), in contrast to men (29% vs. 24% n.s.). Women with a history of abuse and FGID had reduced HRQL 91 (95% CI 85-97) as compared with women without abuse history 100 (95% CI 96-104, P = 0.01, "healthy" = 102-105 on PGWB). Childhood emotional abuse was a predictor for consulting with OR = 4.20 (95% CI: 1.12-15.7.7). Thus, previous abuse is common in women with FGID and must be considered by the physician for diagnosis and treatment of the disorder.

New insights into the pathogenesis and pathophysiology of irritable bowel syndrome

The pathogenesis and pathophysiology of irritable bowel syndrome is complex and still incompletely known. Potential pathogenetic factors include genes, infectious events, psychological symptoms and other loosely defined environmental factors. Both alterations at the central and peripheral level are thought to contribute to the symptoms of irritable bowel syndrome, including psychosocial factors, abnormal gastrointestinal motility and secretion, and visceral hypersensitivity. Today irritable bowel syndrome is viewed upon as a disorder of dysregulation of the so-called brain-gut axis, involving abnormal function in the enteric, autonomic and/or central nervous systems, with peripheral abnormalities probably dominating in some patients and disturbed central processing of signals from the periphery in others. Lines of evidence also suggest that inflammation within the gastrointestinal tract may be of great importance in at least subgroups of irritable bowel syndrome patients. To conclude, a complex picture of the pathogenesis and pathophysiology of irritable bowel syndrome is emerging, with interactions between several different alterations resulting in the divergent symptom pattern in these patients.

Physical health consequences of intimate partner violence in Spanish women

BACKGROUND

Intimate partner violence (IPV) against women can result in serious health problems. The objectives of this study are to analyse the association between the different types of IPV and women's physical health, and to examine whether this association varies depending on the intensity, duration and timing of the violence.

METHODS

A sample of 1402 randomly selected women attending 23 family practices in Spain responded to an anonymous self-reported questionnaire. Measures considered were exposure to physical, sexual and psychological IPV; intensity, duration and timing of such violence; chronic physical disease; number of lifetime surgical operations and number of days spent in bed in the last three months. Descriptive, bivariate and multivariate analyses were conducted.

RESULTS

Lifetime IPV prevalence was 32%. Higher prevalence of chronic disease was observed in abused women than in never abused women, as well as greater number of days spent in bed. Women who reported having experienced the three types of IPV were more likely to suffer a chronic disease (OR = 2.03; 95% CI = 1.18-3.51) and to spend more days in bed (t = 2.35; P = 0.019) than those never abused. Women abused in the past but not in the present presented a higher probability of having a chronic disease than never abused women, and women who had been abused both in the past and in the present had a higher probability of spending more days in bed.

CONCLUSION

IPV can negatively affect physical health of the victims. It is therefore necessary to detect cases of IPV at a primary health care level.

Is functional dyspepsia of particular concern in women? A review of gender differences in epidemiology, pathophysiologic mechanisms, clinical presentation, and management

Dyspepsia is a remarkably common symptom in the general population. Although multiple definitions have been used to describe the symptom, the most common explanation is that of chronic or recurrent pain or discomfort (a subjective negative feeling that may be associated with early satiety, fullness, bloating, or nausea) centered in the upper abdomen. When a thorough evaluation of a dyspeptic patient fails to identify a cause for her symptoms, the label of nonulcer or functional dyspepsia is applied. Functional dyspepsia is a heterogeneous disorder characterized by relapsing and remitting symptoms. Treatment strategies should focus on alleviating the most bothersome symptom and can be based on the proposed underlying pathophysiology. The effect of gender on mechanisms of disease, symptom presentation, and treatment response is an area of increasing interest and study. As with other functional gastrointestinal disorders, there appear to be some gender-specific features of functional dyspepsia. Specifically, gender-related differences have been observed in some studies of both the prevalence of individual dyspepsia symptoms, and in gastric emptying and proximal gastric motor function. There also appear to be gender differences in the psychosocial realm, with dyspeptic women experiencing a lesser sense of well-being than dyspeptic men, as well as an association of an abuse history with functional dyspepsia. This review will highlight specific gender differences related to the symptom presentation, pathophysiology, and approach to treatment of functional dyspepsia, while noting where differences have not been found and where further investigation is warranted.

Functional dyspepsia: Are psychosocial factors of relevance

The pathogenesis of Functional Dyspepsia (FD) remains unclear, appears diverse and is thus inadequately understood. Akin to other functional gastrointestinal disorders, research has demonstrated an association between this common diagnosis and psychosocial factors and psychiatric morbidity. Conceptualising the relevance of these factors within the syndrome of FD requires application of the biopsychosocial model of disease. Using this paradigm, dysregulation of the reciprocal communication between the brain and the gut is central to symptom generation, interpretation and exacerbation. Appreciation and understanding of the neurobiological correlates of various psychological states is also relevant. The view that psychosocial factors exert their influence in FD predominantly through motivation of health care seeking also persists. This appears too one-dimensional an assertion in light of the evidence available supporting a more intrinsic aetiological link. Evolving understanding of pathogenic mechanisms and the heterogeneous nature of the syndrome will facilitate effective management. Co-morbid psychiatric illness warrants treatment with conventional therapies. Acknowledging the relevance of psychosocial variables in FD, the degree of which is subject to variation, has implications for assessment and management. Available evidence suggests psychological therapies may benefit FD patients particularly those with chronic symptoms. The rationale for use of psychotropic medications in FD is apparent but the evidence base to support the use of antidepressant pharmacotherapy is to date limited.
