OBJECTIVE: To examine binge eating, depression, weight self-efficacy, and weight control success among obese individuals seeking treatment in a managed care organization.DESIGN: Gender-stratified analyses of associations between binge eating, depression, weight self-efficacy, and weight change, using data from a randomized clinical trial that compared low-cost telephone-based, mail-based, and usual care interventions for weight loss.SUBJECTS: A total of 1632 overweight individuals (460 men, 1172 women; mean age: 50.7 y; mean body mass index: 34.2 kg/m2) were recruited from a large Midwestern US managed care organization.MEASUREMENTS: Height and weight were measured by study personnel at baseline, and self-reported weight was assessed at 6 and 12 months; self-reported depression status, binge eating, and self-efficacy for weight control were assessed at baseline.RESULTS: Lifetime prevalence rates for depression and probable binge eating disorder were high. Weight self-efficacy was inversely related to weight in both men and women. For women, depression was associated with lower weight self-efficacy and higher body weight. Women reporting depression or lower weight self-efficacy at baseline had less weight loss success at 6 and 12 months. Depression, binge eating disorder, and weight self-efficacy were not significantly associated with weight loss success in men.CONCLUSION: Negative emotional states are highly prevalent and predict poor treatment outcomes, particularly for obese women. As obese women with clinical depression typically are excluded from intervention studies, further research on how to address the intersection of obesity intervention and mood management may be warranted.

Abstract OBJECTIVE: Previous research, based on retrospective reporting, suggests that parental reinforcement and modeling may be important mechanisms in the development of gastrointestinal illness behavior in children and adults. The aim of this study was to determine the relationship between the illness behavior of parents, in the form of health care use for irritable bowel symptoms, and the illness behavior of their children, without relying on retrospective recall. METHODS: A comparison of two matched groups was made. Groups included 631 children of parents who were diagnosed with irritable bowel syndrome during 1 calendar yr and 646 children of parents matched by parental age, gender, and number of children in the family who did not receive an IBS diagnosis during the same 1 yr. Health care use and costs over a 3-yr calendar period for all children and their parents collected from the health care database of a large health maintenance organization were evaluated. RESULTS: Case children had significantly more ambulatory care visits for all causes (mean 12.26 vs 9.81, p = 0.0001) and more ambulatory visits for gastrointestinal symptoms (0.35 vs 0.18, p = 0.0001). Outpatient health care costs over the 3-yr period were also significantly higher for case than control children (

1546, p = 0.0001). Controlling for the total number of ambulatory visits of the parents, excluding gastrointestinal visits, did not alter the findings. Gender of the IBS parent was not related to children’s gastrointestinal visits. CONCLUSION: This study extends previous research by showing that specific types of illness behavior may be learned through modeling.

OBJECTIVES:Irritable bowel syndrome (IBS) runs in families. The aims of this study were (i) to exclude biased perception by a mother with irritable bowel as the explanation for increased gastrointestinal (GI) symptoms in their children, (ii) to determine whether non-GI as well as GI symptoms run in families, and (iii) to determine whether parent IBS status and solicitous responses to illness exert independent effects on childrens symptom reports, medical clinic visits, and school absences.METHODS:Two hundred and eight mothers with irritable bowel and their 296 children (cases: average age 11.9 yr; 48.6% male) and 241 nonirritable bowel mothers and their 335 children (controls: 11.8 yr; 49.0% male) were interviewed. Other factors assessed were stress, mothers and childs psychological symptoms, childs perceived competence, pain coping style, age, and sex. Children were interviewed apart from their parents.RESULTS:Case children independently reported more frequent stomach aches (F(591) = 9.22; p= 0.0025) and non-GI symptoms (F(562) = 21.03; p < 0.001) than control children. Case children also had more school absences (F(625) = 26.53; p < 0.0001), physician visits for GI symptoms (F(602) = 8.09; p= 0.005), and non-GI clinic visits (F(602) = 27.92; p < 0.001) than control children. Children whose mothers made solicitous responses to illness complaints independently reported more severe stomach aches (F(590) = 11.42; p < 0.001), and they also had more school absences for stomach aches (F(625) = 5.33; p < 0.05), but solicitous behavior did not significantly impact non-GI symptom reporting, clinic visits, or school absences. Differences between cases and controls remained significant after adjusting for potential moderators.CONCLUSIONS:(i) Frequent GI complaints in children whose mothers have irritable bowel are not explained by the mothers biased perceptions; (ii) children of mothers with irritable bowel have more non-GI as well as GI symptoms, disability days, and clinical visits; (iii) and parent IBS status and solicitous responses to illness have independent effects on the childs symptom complaints.

Abstract OBJECTIVES: The aims of this study were: 1) to determine the total costs of care and costs related to lower GI–related problems for patients who received a diagnosis of irritable bowel syndrome (IBS), and 2) to compare them to age- and sex-matched population controls and patients treated for inflammatory bowel disease (IBD) or gastroesophageal reflux disease (GERD). METHODS: Use and cost data were obtained through the computerized information systems of a large staff-model health maintenance organization on three groups of patients diagnosed in 1994 or 1995 with IBS, IBD, or GERD; and an age- and sex-matched control group of patients without any of these listed diagnoses. The IBS patient group was compared to the three comparison groups on components of total and IBS-related costs. RESULTS: Total costs of care for IBS patients were 49% higher than population controls during the year starting with the visit at which IBS patients were identified. In the index year, every component of total costs except inpatient care was significantly higher for IBS patients than for population controls. The costs of care for lower GI problems were significantly higher for patients with IBS than for population controls across a range of services. However, only 33% of the difference in total costs of care between IBS patients and population controls was due to lower GI–related services in the index year. In the subsequent years, lower GI–related services accounted for 18% and 20% of the total cost difference between IBS patients and population controls. The total costs of care as well as the components of costs of care were generally higher for IBD patients than for IBS patients, but were comparable for GERD and IBS patients. CONCLUSIONS: Patients with IBS show sustained increases in health care costs relative to population controls for both lower GI services and care unrelated to lower GI problems. However, the majority of the excess in health care costs resulted from medical care not directly related to lower GI problems.

The relationship between daily life stress and gastrointestinal symptoms in women with irritable bowel syndrome.

Rona L. Levy; Kevin C. Cain; Monica Jarrett

Objective: The aim was to determine whether lower visceral pain thresholds in irritable bowel syndrome (IBS) primarily reflect physiological or psychological factors. Methods: Firstly, 121 IBS patients and 28 controls underwent balloon distensions in the descending colon using the ascending methods of limits (AML) to assess pain and urge thresholds. Secondly, sensory decision theory analysis was used to separate physiological from psychological components of perception: neurosensory sensitivity (p(A)) was measured by the ability to discriminate between 30 mm Hg vs 34 mm Hg distensions; psychological influences were measured by the report criterion—that is, the overall tendency to report pain, indexed by the median intensity rating for all distensions, independent of intensity. Psychological symptoms were assessed using the Brief Symptom Inventory (BSI). Results: IBS patients had lower AML pain thresholds (median: 28 mm Hg vs 40 mm Hg; p<0.001), but similar neurosensory sensitivity (median p(A): 0.5 vs 0.5; p = 0.69; 42.6% vs 42.9% were able to discriminate between the stimuli better than chance) and a greater tendency to report pain (median report criterion: 4.0 (“mild” pain) vs 5.2 (“weak” pain); p = 0.003). AML pain thresholds were not correlated with neurosensory sensitivity (r = −0.13; p = 0.14), but were strongly correlated with report criterion (r = 0.67; p<0.0001). Report criterion was inversely correlated with BSI somatisation (r = −0.26; p = 0.001) and BSI global score (r = −0.18; p = 0.035). Similar results were seen for the non-painful sensation of urgency. Conclusion: Increased colonic sensitivity in IBS is strongly influenced by a psychological tendency to report pain and urge rather than increased neurosensory sensitivity.

OBJECTIVES:The Rome III classification system treats functional constipation (FC) and irritable bowel syndrome with constipation (IBS-C) as distinct disorders, but this distinction appears artificial, and the same drugs are used to treat both. This studys hypothesis is that FC and IBS-C defined by Rome III are not distinct entities.METHODS:In all, 1,100 adults with a primary care visit for constipation and 1,700 age- and gender-matched controls from a health maintenance organization completed surveys 12 months apart; 66.2% returned the first questionnaire. Rome III criteria identified 231 with FC and 201 with IBS-C. The second survey was completed by 195 of the FC and 141 of the IBS-C cohorts. Both surveys assessed the severity of constipation and IBS, quality of life (QOL), and psychological distress.RESULTS:(i) Overlap: if the Rome III requirement that patients meeting criteria for IBS cannot be diagnosed with FC is suspended, 89.5% of IBS-C cases meet criteria for FC and 43.8% of FC patients fulfill criteria for IBS-C. (ii) No qualitative differences between FC and IBS-C: 44.8% of FC patients report abdominal pain, and paradoxically IBS-C patients have more constipation symptoms than FC. (iii) Switching between diagnoses: by 12 months, 1/3 of FC transition to IBS-C and 1/3 of IBS-C change to FC.CONCLUSIONS:Patients identified by Rome III criteria for FC and IBS-C are not distinct groups. Revisions to the Rome III criteria, possibly including incorporation of physiological tests of transit and pelvic floor function, are needed.

Social support and compliance: A selective review and critique of treatment integrity and outcome measurement.

Rona L. Levy

Research on irritable bowel syndrome (IBS), a functional disorder of the gastrointestinal (GI) system, has linked GI symptoms to stress. This study examined the relationship between daily stress and GI symptoms across women and within woman in IBS patients (n = 26), IBS nonpatients (IBS-NP; n = 23), and controls (n = 26), controlling for menstrual cycle phase. Women (ages 20–45) completed daily health diaries for two cycles in which they monitored daily GI symptoms and stress levels. The Life Event Survey (LES) was used as a retrospective measure of self-reported stress. The across-women analyses showed higher mean GI symptoms and stress in the IBS and IBS-NP groups relative to controls but no group differences in LES scores. The within-woman analyses found a significant and positive relationship between daily stress and daily symptoms in both the IBS-NP and the IBS groups. Controlling for menstrual cycle had no substantial impact on the results.
