Precipitants of constipation during early childhood.
BACKGROUND: Childhood constipation is a common problem, accounting for 3% of visits to pediatric clinics and 30% of visits to pediatric gastroenterologists. Estimates of the prevalence of childhood constipation vary from 0.3% to 28% with younger children being affected most often. We were unable to find any studies that specifically examine the causes of constipation in young children. Our objective of the study was to determine precipitants to constipation during early childhood. METHODS: Findings from 125 families visiting their primary care physician for the first time with a child aged between 2 and 7 years with the complaint of constipation were compared with findings from 95 children between 2 and 7 years without any history of constipation. Parents answered questions concerning family history, toilet training, and bowel habits. Parents of constipated children were asked to describe events that occurred during the 3 months before the onset of constipation and whether these events contributed to the child's constipation. RESULTS: The age and sex of children who did and did not suffer from constipation were comparable (P > .3). When compared with control children, constipated children were no more likely to have a parent (30% vs 40%, P = .14) or sibling (17% vs 14%, P = .54) with a history of constipation. Constipated children did not begin toilet training earlier than did control children (28 +/- 7 vs 27 +/- 6 months, P = .30). When compared with parents of control children, parents of constipated children reported more difficulties with toilet training (P < .001). Parents of constipated children indicated their children had more difficult and more painful defecation experiences than did parents of control children (P < .001), and constipated children were more likely to express worry about future painful defecation than were control children (P < .001). Parents of constipated children described a number of events that occurred before the onset of constipation; however, they did not consider many of the events important contributors to the constipation. Painful defecation was the event most often reported as causing the constipation. CONCLUSION: Painful defecation is the primary precipitant of constipation during early childhood. Parents should be counseled to be attentive to such experiences and taught to intervene quickly to lessen the risk that their child will develop persistent constipation or fecal soiling.

[Case-control study of risk factors associated with constipation. The FREI Study].
BACKGROUND: Children represent one of the patient groups most affected by constipation. Our objective was to identify and describe the risk factors associated with childhood constipation. PATIENTS AND METHODS: The study had a case-control, retrospective, open and multicenter design. Clinical data on possible risk factors were collected through an ad-hoc questionnaire. Two groups were studied: children with and without constipation. RESULTS: Nine hundred twenty-one children were recruited; of these, 898 (97.6%) were included in the statistical analysis. There were 408 (45.4%) children in the constipated group and 490 (54.5%) in the non-constipated group. Most of the children with constipation (53.6%) had a maternal history of constipation compared with 21.4% of children without constipation (p < 0.05). More than half (53.2%) of the constipated children reported a lack of regularity in their toilet habits while 64.9 % of the children without constipation went to the toilet regularly. Toilet training started slightly earlier (at 3 years) in children without constipation (93.2%) than in those with the disorder (83.8%) (p < 0.05). At school, 57.4% of the children with constipation never used the toilet compared with 26.8% of those without constipation (p < 0.05). A total of 73.4% of children with constipation drank less than four glasses of water per day compared with 47.1% of those without constipation (p < 0.05). Consumption of vegetables and legumes in the diet was significantly lower in children with constipation than in those without (p < 0.05). The risk factors linked to childhood constipation found in this study were a familial history of constipation, irregular toilet habits, low dietary fiber contents and no fruit intake. The main preventive factors against constipation were water and vegetable consumption and training on the use of the toilet at school. CONCLUSIONS: Daily toilet training and dietary changes are needed to prevent constipation among children and to achieve regular defecation. This preventive intervention should be reinforced at school.

Revalidation of description of constipation in terms of recall bias and visual scale analog questionnaire.
BACKGROUND AND AIM: The present study was designed to identify a cut-off value to define subjective and relatively objective criteria of constipation using the visual scale analog questionnaire (VSAQ) in healthy subjects. In addition, the importance of recall bias when evaluating constipation was investigated by repeating the questionnaire and ensuring the subjects maintained diaries. METHODS: Seven hundred and sixty healthy hospital personnel were questioned by means of a standard questionnaire. Subjects were initially asked if they were constipated (self-reported) and their daily defecation frequencies. Severity of the parameters of constipation, the consistency of defecation in the form of hard stools, straining and incomplete evacuation were also investigated using a VSAQ (0-10). Subjects were asked to complete a standard form about their daily bowel habits in the subsequent 7 days (diary). At the end of this series, the questionnaire forms completed at the beginning were readministered. Using the criteria of functional constipation, the prevalence of self-reported, symptom-based (>/=2 criteria) and diary-based (>/=2 criteria in the diary) were defined. RESULTS: Of the subjects, 48.5% (369/760) completed diaries regarding their bowel habits and completed the questionnaire for the second time (198 female, 171 male; mean age 31.6 +/- 7.1 years). According to only interrogation, 29.8% of subjects reported that they were constipated; however, this number increased to 39.6% when symptom-based constipation (>/=2 criteria) was considered. Significant agreement was observed between the results of self-reported constipation in form I and II, and symptom-based and diary-based constipation (concordance = 77.7-98.6%, k = 0.47-0.97). Furthermore, 98.1% of the subjects who reported that they were not constipated scored 3 on the VSAQ; conversely, 91.8% who accepted being constipated scored >3 for the same question. A total of 76.1% subjects who had symptom-based constipation scored 3 on the VSAQ, 97.3% of those who had <2 criteria scored 3. When asked 'Are you constipated?' 1.2% of subjects with none of the criteria for diary-based constipation, and 10.7% of subjects who had one criteria scored >3 on the VSAQ. Also, 91.8% of those with three criteria and 100% of those with four criteria had a score >3 on the VSAQ for the same question. CONCLUSIONS: The prevalence of constipation in the questionnaire form based on self-reported, symptom-based and diary-based criteria were highly compatible with the result obtained on readministration. Recall bias was negligibly low. Also, the present results suggest that the diagnosis of constipation is more accurate when >2 criteria are present. In addition, the VSAQ seems to be sensitive enough to differentiate subjects with constipation from those without, when a score of 3 has been chosen as the cut-off value for discrimination. However, this sensitivity was less in the group who stated they were constipated.

Diagnosis of constipation in family practice.
BACKGROUND: Patients who complain of constipation to their family doctor may not be truly constipated. Variability in stool frequency and consistency, and perception of symptoms may lead to inaccurate patient reporting or diagnosis of constipation. OBJECTIVES: To determine whether patients visiting their family doctor with a complaint of, or diagnosed with, constipation fulfilled the Rome II criteria for functional constipation and had stool characteristics of constipation. METHODS: A random sample of Canadian family physicians were recruited to enroll a series of adults who complained of, or had received a diagnosis of, constipation during an office visit. Patients were advised of the survey. Those providing written consent were contacted by an independent research firm and forwarded a survey questionnaire that included the Rome II gastrointestinal questionnaire, questions regarding their medical history and questions regarding their demographics. Patients also completed a four-week daily diary recording their bowel habits using the Bristol Stool Form Scale, medication use and satisfaction with treatment. Questionnaire and diary responses were retrieved by telephone. RESULTS: One hundred eighty-four family physicians enrolled 311 patients, of whom 220 completed the questionnaire. Females comprised 79.5% of the sample and had a mean age of 54.2 years (males 61.6 years; P<0.05). According to the Rome II criteria, 37.3% had functional constipation and 46.8% had irritable bowel syndrome (IBS). Whole gut transit times estimated using the Bristol Stool Scale were similar among those with self-reported constipation, those with Rome II functional constipation and those with Rome II IBS (79.3 h, 85.8 h and 77.4 h, respectively). Almost half of the patients with IBS or functional constipation were taking a pain medication, while nearly one-fifth took antidepressants. Of the medications or remedies taken to treat constipation, patients rated 49.8% of the doses as satisfactory. CONCLUSIONS: A large proportion of Canadian primary care patients whose presenting complaint or diagnosis was constipation satisfied the Rome II criteria for IBS, with a smaller number defined as functionally constipated. IBS patients tended to be younger than those with functional constipation, and whole gut transit times did not differentiate IBS from functional constipation. Careful questioning of patients who complain of constipation may reveal constipating medication, diarrhea symptoms or IBS.

[Intake of dietary fiber and other nutrients by children with and without functional chronic constipation].
The aim of this study was to evaluate the dietary fiber intake and the dietary habits of children with and without functional chronic constipation. We enrolled 58 children with functional chronic constipation and 58 controls without constipation matched for sex and age. Food and fiber intake were evaluated by 24 hour dietary recall and a complete clinical history was performed. The age of onset of constipation occurred during the first year of life in 55.4% of the patients while the median age of evaluation was 78 months. Soiling was found in 41.7% of patients. The median period of exclusive breast feeding was shorter (P = 0.002) in the constipation group (one month) than in the control group (three month). The proportion of constipation was similar for mothers of children of both groups as well as for siblings in both groups. The fathers of children with constipation presented higher frequency of constipation (12.3%) than the fathers of children in control group (1.8%), but the difference did not reach statistical significance (P = 0.06). The amount of food measured by 24 hour recall was similar in both groups. The calorie intake of constipated children (1526 +/- 585 calories/day) was lower (P = 0.07) than in the control group (1712 +/- 513 calories/day) but the difference did not reach statistical significance. The intake of protein, fat and iron was lower in the constipation group than in the control group. The volume of cow's milk intake was similar in both groups. The median of total dietary fiber intake in the constipation group (13.5 g/day) was statistically (P = 0.009) lower than in the control group (16.8 g/day). The daily intake of insoluble dietary fiber was also statistically lower (P = 0.001) in the constipation group (6.3 g) than in the control group (9.4 g). The intake of soluble dietary fiber was similar in both groups. The intake of dietary fiber per 1,000 calories of diet was 10.3 g in the constipation group and 10.4 in the control group (P = 0.41). There was a considerable intersection of individual values in fiber intake of the constipation and control groups, suggesting that low fiber intake acts in association with others factors on the genesis of constipation in children. However, the low intake of insoluble fiber, suggests that it plays an important role on the pathogenesis of chronic constipation in children.

Constipation in the elderly.
OBJECTIVE: To explore the distinction between true clinical constipation and the subjective complaint of constipation in elderly people and to review the pathophysiology, symptoms, diagnosis, causes, and treatment. DATA SOURCES: A computer-assisted and manual search of the English language literature using MEDLINE 1966-1991, Index Medicus 1988-1992, reference lists of selected articles, and relevant textbooks. STUDY SELECTION: Studies that provide information on lower bowel function and laxative and enema use in the elderly subjects were reviewed. Article selection was not limited by study design. DATA EXTRACTION: Relevant data were abstracted from the results of physiological, cohort and case-control studies, and clinical trials. The text discusses the methodological strengths and flaws of these studies and excludes management approaches formulated from uncontrolled clinical observation. RESULTS OF DATA SYNTHESIS: Constipation of the elderly is not well defined in the current literature. Self-reported constipation and laxative use increase with age, while a similar escalation in true clinical constipation is not shown. Physiological changes in the lower bowel predisposing toward constipation do not occur with normal aging. Patient selection criteria for studies examining the pathophysiology of constipation differ in their definition of constipation and their inclusion of coexisting chronic illness. Nevertheless, there is consistent evidence for prolonged transit through the sigmoid colon and rectum, especially in frail elderly patients, and reduced rectal tone with impaired sensation, particularly in patients with rectal impaction. Few studies rigorously examine "risk factors" and non-pharmacological interventions in constipation. The results of most laxative trials require cautious interpretation because of inclusion of patients without diagnostically proven constipation, use of combined laxative preparations, and unreliable outcome measures. Certain laxative agents however appear more appropriate for use in elderly people. CONCLUSION: Although the subjective complaint of constipation and habitual laxative use increase with age, the epidemiological data suggest that true clinical constipation does not. Physiological changes predisposing toward constipation are not an inevitable consequence of aging, but appear to be specific to the condition. The available data do not confirm many suspected "risk factors" nor the benefits of commonly used non-pharmacological and pharmacological treatments, but they do provide enough information to formulate a practical approach to constipation in elderly persons.

Increased prevalence of obesity in children with functional constipation evaluated in an academic medical center.
OBJECTIVE: The rapidly increasing prevalence of obesity in children is the most important problem facing pediatricians today. A recent study suggested an association of obesity and constipation in children but lacked a control group for comparison. The objectives of this study were to evaluate the prevalence of obesity in a large cohort of children with functional constipation and to compare it with a control group representative of the general population. METHODS: Retrospective chart review was performed on 719 children, between the ages of 4 and <18 years, with chronic functional constipation seen in the general pediatric and pediatric gastroenterology clinics between July 2002 and June 2004. Data collected included age, gender, BMI, and signs and symptoms of constipation including fecal incontinence. Obesity was classified as a BMI of >95th percentile and severe obesity as a BMI of > or =5 kg/m2 above the 95th percentile for age and gender. The control group consisted of all 930 children (4 to <18 years of age) presenting to the pediatric clinic for a well-child visit between January and June 2004. The chi2 and t tests were used for analysis. RESULTS: Overall prevalence of obesity was significantly higher in constipated children (22.4%) compared with control children (11.7%), and this higher prevalence was also seen for severe obesity. The prevalence rates of obesity were significantly higher in constipated males (25%) than in constipated females (19%) and were significantly higher compared with the control males (13.5%) and control females (9.8%). Constipated boys in all 3 age groups had significantly higher rates of obesity than the control boys; the constipated girls had significantly higher obesity rates for the age groups between 8 and <18 years. Fecal incontinence (encopresis) was present in 334 of 719 (46%) constipated children. The prevalence of obesity was similar in constipated children with and without fecal incontinence. CONCLUSIONS: There is a significantly higher prevalence of obesity in children with constipation compared with age- and gender-matched controls. This higher prevalence is present in both boys (4 to <18 years of age) and girls (8 to <18 years of age) with constipation and is not related to the presence of fecal incontinence among constipated children. The higher prevalence of obesity may be a result of dietary factors, activity level, or hormonal influences and needs additional evaluation.

[Dermatoglyphics of children with chronic constipation].
BACKGROUND: The dermatoglyphics can be used to study the participation of genetic factors in many diseases. There is controversy concerning the association between the dermatoglyphic pattern of digital arches and constipation. AIM: To compare the dermatoglyphic patterns among children with and without chronic constipation in relation to the dermatoglyphic patterns and characteristics of stools of their mothers. METHODS: Three groups of children aged from 2 to 12 years and their mothers were studied: 35 patients with severe chronic constipation, 45 children with mild chronic constipation and 51 children without constipation. The fingerprints were taken and evaluated by a datiloscopy technicist and classified in arch, radial loop, ulnar loop, whorl and others. RESULTS: Digital arches were found in 25.7% of severe constipated patients, 28.9% of mild constipated children and in 23.5% of controls. There was not a statistical significant association. Constipation was found in 51,9% (68/131) of the mothers. Arches were found in 35.3% of the mother with constipation and in 42.9% of mothers without constipation. There was a slight association between constipation in children and in theirs mothers (Kappa coefficient = +0.16). CONCLUSION: The dermatoglyphics were not useful to identify the influence of genetic in constipation. There was not association between the dermatoglyphic pattern of digital arch and constipation both in children and in their mothers. Only a slight concordance was found between constipation in children and in their mothers.

Life style risks of Parkinson's disease: association between decreased water intake and constipation.
Gastrointestinal dysfunction, especially constipation, is one of the major problems in the daily life of patients with Parkinson's disease (PD). About 60 to 80% of PD patients suffer from constipation. Several studies have proven that constipation appears about 10 to 20 years prior to motor symptoms. More recently, Abbott et al. have found from a large scale prospective study that lower frequency bowel movements predict the future risk of PD. Furthermore, Braak et al. have found that Lewy neuritis and Lewy bodies, the hallmarks of PD pathology, appear in the dorsal nucleus of vagus in the earliest stage of the disease and then extend upward through the brain stem to reach the substantia nigra in the third stage. They also hypothesize that some yet undefined toxins break through the mucosal barrier of the intestine and are incorporated into the axon terminal of the vagus nerve and transported in a retrograde manner to the vagus nucleus. In this study, we assessed bowel movements and nutritional status in Japanese patients with PD. We found that intake of water was significantly decreased in PD patients from early life and associated with their constipation. Ninety four patients with PD (M 50, F 44) were enrolled. Nutritional status was assessed using the Self-administered Diet History Questionnaire (DHQ). Total water intake was calculated from the consumption of coffee, green tea, and tea. We also questioned the behavior of water drinking from the early stage of life. The questionnaire for bowel movements concerned the frequency of defecation, age of onset of constipation, and age of onset of motor dysfunction. Less than one bowel movement in 3 days was defined as constipation. The nutritional status of PD patients did not differ significantly from those of controls though several studies have shown excess intake of animal fats or reduced consumption of coffee are risks in PD. In contrast, water intake was significantly lower in PD patients than controls (604.0+/-377.2 ml/d vs 909.5+/-531.6 ml/d; P<0.0001). Interestingly, PD patients tended not to feel thirsty and thus they had no desire to drink water throughout their life. Seventy four patients out of 94 (78.7 %) complained of constipation. Mean bowel frequency was once per 3.3+/-1.1 days and 71.1% of patients were defined as having constipation. Women suffered from constipation more frequently than men (82.4% vs 61.9 %). In 33 patients out of 74 (44.6 %), onset of constipation preceded motor disturbance by an average time of 18.1+/-18.8 years. Furthermore, the amount of water intake correlated inversely with the severity of constipation and the depletion of water intake preceded constipation in most cases. The present results support previous findings that constipation precedes the onset of motor dysfunction in PD. To our knowledge, this is the first report to point out latent water depletion in PD patients. It is not certain at present whether coffee or caffeine themselves are the protective factor for PD or alternatively the amount of water in coffee drinking is more essential. Prospective studies on a large scale are necessary to elucidate the real meaning of water depletion in PD.

Prolonged stationary colonic motility recording in seven patients with severe constipation secondary to antidepressants.
The aim of this study was to determine whether the colonic motor profile of seven patients with constipation secondary to antidepressants differed from the motility of seven patients with idiopathic constipation and seven healthy volunteers. All constipated patients had very severe constipation. Colonic manometric recordings were performed for 24 h. The number of high amplitude propagating contractions (HAPC) was lower in the two groups of constipated patients than in controls. No HAPC were observed in 5/7 patients with constipation secondary to antidepressants and in 1/7 patients with idiopathic constipation. The overall area under the curve (AUC) in the left colon was lower in the two constipated patient groups than in controls. AUC increased after a 1000-kcal standard meal given at noon in controls but not in the two groups of constipated patients. In conclusion, in patients with constipation secondary to antidepressants, the overall AUC was as poor as in patients with idiopathic constipation, and no colonic response to eating was observed. Moreover, the number of HAPC was more markedly decreased in patients with constipation secondary to antidepressants than in patients with idiopathic constipation.

Validated questionnaire on diagnosis and symptom severity for functional constipation in the Chinese population.
BACKGROUND: Functional constipation is a common problem in clinical practice. No validated questionnaire is available in Chinese. AIM: To develop a validated questionnaire for diagnosis and symptom assessment in functional constipation for the Chinese population. METHODS: One hundred and eleven patients with constipation and 110 healthy controls were presented with a 24-item constipation questionnaire in the Chinese language. Quality of life in constipation patients was assessed by Short Form-36. Polyethylene glycol was prescribed, for 4 weeks, to 20 patients with newly diagnosed constipation. The questionnaire was administered before and 4 weeks after treatment. Concept, content, construct, discriminant validity and reliability of the questionnaire were assessed. RESULTS: Six items were selected by logistic regression to account for most of the differences between controls and constipated patients with a good reproducibility and internal consistency. A cut-off score of > or =5 was determined to discriminate between controls and constipated patients with a sensitivity of 91% and a specificity of 91%. The constipation questionnaire correlated negatively with seven domains of the Short Form-36 and discriminated between constipated patients who reported symptomatic improvement during polyethylene glycol treatment. CONCLUSIONS: The Chinese constipation questionnaire could be used in epidemiological studies to assess the frequency and severity of constipation in patient populations and in interventional studies of constipation.

Definitions, epidemiology, and impact of chronic constipation.
Constipation, however it is defined, is a common problem in the community. The exact prevalence of constipation depends on the definition used; prevalence estimates range from 2% to 28%. The prevalence of constipation has been stable because the onset and disappearance rates over time are similar, but accurate data on the incidence of constipation are lacking. Approximately one third of those individuals with constipation seek health care; this is an expensive fraction due to investigational and medication costs. The evidence that life-style factors are causally linked to constipation is weak, although nonsteroidal anti-inflammatory drug use and the use of other constipation-inducing medications are important risk factors. Constipation is not of clinical importance until it causes physical risks or impairs quality of life. There is accumulating evidence that self-reported constipation and functional constipation as defined by the Rome Criteria lead to significant impairment of quality of life, with the implication that this is a serious condition in the majority of people afflicted. Constipation may have other serious consequences; an increased risk of colon cancer has been reported but could be explained by confounding. Although hemorrhoids have been attributed to constipation, this association has been questioned. The costs of testing in patients presenting with constipation has been conservatively estimated to be 6.9 billion dollars annually in the United States; treatment costs add substantially to the health care burden.

Development of constipation in nursing home residents.
PURPOSE: Constipation is a common complaint among geriatric patients and may result in significant morbidity, especially among nursing home residents. The prevalence of constipation increases with advancing age and may be a result of the aging process, but the exact cause is unknown. The aim of this study was to describe the prevalence of constipation and to determine risk factors for the development of constipation in a large population of nursing home residents. METHODS: The Minimum Data Set is an assessment instrument used in nearly all Medicare-certified and Medicaid-certified nursing facilities. Nursing home residents who were at least 65 years of age and who had assessments at baseline and at three months were included in the study (N = 21,012). Baseline risk factors were included in a multivariate logistic regression to determine their association with the development of constipation. To allow causal implications, nursing home residents with constipation at baseline were excluded. The variables examined included medications, mobility, comorbid illness, and nutrition. RESULTS: The mean age (+/- standard deviation) of nursing home residents was 83 +/- 8 years, and the population was 70 percent female and 83 percent white. At baseline, the prevalence of constipation was 12.5 percent (N = 2,627). By the three-month assessment, 7 percent (N = 1,291) of nursing home residents had developed constipation. The factors associated independently with the development of constipation were, in order of magnitude, race, decreased fluid intake, pneumonia, Parkinson's disease, and the presence of allergies. Congestive heart failure and the use of a feeding tube were two factors identified as having a protective effect. CONCLUSION: The variables associated with the development of constipation may be used to identify geriatric nursing home residents at risk and to prevent constipation and its potential complications. Further study is needed to demonstrate a causal relationship between the risk factors and the development of constipation.

Constipation management in palliative care: a survey of practices in the United kingdom.
Fifty percent of patients admitted to hospices cite constipation as a concern. This study evaluates how constipation was managed in 11 hospices. Patients and nurses completed questionnaires at two time points: baseline and 7-10 days later. Outcomes were evaluated using a Constipation Visual Analogue Scale and a satisfaction with management of constipation questionnaire. A total of 475 patients participated; 413 completed both assessments. Forty-six percent of patients reported no constipation and 15% of patients reported severe constipation. For 75% of patients, no change in the perception of constipation was observed over the study period. Patients expressed satisfaction with their constipation management. The severity of constipation was overestimated by nurses in many patients. The findings indicate that constipation was being prevented or reasonably well managed. However, severe constipation continues to be a problem. Assessment of patients' bowel function needs to be more rigorous and those identified as severely constipated need daily monitoring.
