The burden of constipation on quality of life: results of a multinational survey.

BACKGROUND: The impact of constipation on quality of life (QoL) may vary in different cultural or national settings. AIM: We studied QoL in a multinational survey to compare different social and demographic groups with and without constipation (defined according to Rome III criteria) and to detect country-specific differences among the groups studied. METHODS: Health-related QoL (HRQoL) was assessed with the Short Form 36 (SF-36) questionnaire in 2870 subjects in France, Germany, Italy, UK, South Korea, Brazil and USA. Results Respondents were mainly middle-aged, married or living together and part- or full-time employed. General health status, measured by the SF-36 questionnaire, was significantly worse in the constipated vs. non-constipated populations. RESULTS: were comparable in all countries. QoL scores correlated negatively with age. Constipated women reported more impaired HRQoL than constipated men. Brazilians were most affected by constipation as to their social functioning (35.8 constipated vs. 51.3 non-constipated) and general health perception (29.4 constipated vs. 54.4 non-constipated). CONCLUSIONS: There are significant differences in HRQoL between constipated and non-constipated individuals and a significant, negative correlation between the number of symptoms and complaints and SF-36 scores. The study detected a correlation of constipation with QoL and the influence of social and demographic factors on HRQoL in constipated people.

Prevalence and management of abdominal cramping and pain: a multinational survey.

BACKGROUND: Though functional gastrointestinal complaints are recognised as being common throughout the world, there have been few comparative studies of prevalence. AIM: To compare the prevalence and management of abdominal cramping/pain in nine countries. METHODS: In a two-stage community survey, approximately 1000 subjects were interviewed in each of nine countries to establish the demographics of individuals with abdominal cramping/pain (stage 1) followed by market research-driven interviews with >or=200 sufferers per country (stage 2). RESULTS: 9042 subjects were interviewed in stage 1. Mexico (46%) and Brazil (43%) had the highest prevalence of abdominal cramping/pain; Japan the lowest (10%). Abdominal cramping/pain was more common in women (12-55%) than in men (7-38%). About 1717 subjects participated in stage 2; 65% were women and the average age at symptom onset was 29 years. The frequency of episodes differed between countries, being highest in the US (61% suffered at least once in a week). Sufferers in the US and Latin America reported a higher usage of medications (around 90%) than those in Europe (around 72%). In most countries over-the-counter drugs were principally used. Antispasmodic drugs were most popular in Latin America and Italy, antacids in Germany and the UK. Drug therapy decreased the duration of episodes (by up to 81% in Brazil). CONCLUSIONS: The community prevalence, severity, healthcare seeking and medication usage related to abdominal cramping/pain are high overall, but vary considerably between countries.

Drug treatment of chronic-intermittent abdominal cramping and pain: a multi-national survey on usage and attitudes.

BACKGROUND: Data on drug treatment of abdominal cramping and pain are sparse. AIM: To compare treatment of abdominal cramping and pain across countries worldwide. METHODS: A multi-national survey was conducted in the USA, Mexico, Brazil, Argentina, Germany, Belgium, Italy and the UK. In each country, approximately 210 people were interviewed on various aspects of drug treatment of their complaints. RESULTS: In total, 1717 participants were interviewed. Respondents from the Americas used more medication (approximately 90%) than those from Europe (approximately 70%). Over-the-counter remedies were much more used than prescription drugs (except for Mexico). Medication was mainly taken on demand to relieve a pain episode. In the Latin American countries, antispasmodics were most popular (up to 73%), in Germany antacids, and in the UK antacids and analgesics. Regarding expectations of treatment, 'fast onset of action' ranked the highest, followed by 'highly effective' and 'well tolerated'. CONCLUSIONS: A majority of people afflicted by abdominal cramping and pain use medication and take them on demand. Consequently, rapid onset of action is mentioned as most important. Antispasmodics are the class most frequently used with considerable variation from country to country.

A multinational survey of prevalence and patterns of laxative use among adults with self-defined constipation.

BACKGROUND: While numerous studies report prevalence of constipation, use of laxatives is poorly understood. AIM: To conduct a survey in seven countries evaluating prevalence of constipation and laxative use in its treatment. METHODS: Thirteen thousand eight hundred seventy-nine adults [approximately 2000 each from US, UK, Germany (GE), France (FR), Italy (IT), Brazil (BR) and South Korea (SK)] completed questionnaires assessing occurrence, frequency, duration and laxative use for treating constipation. RESULTS: Overall, 12.3% of adults had constipation [range: 5% (GE) to 18% (US)] in the prior year. A greater percent of women from all countries and elderly from all except SK and BR reported constipation; odds ratios for constipation among women and elderly were 2.43 (95% CI: 2.18-2.71) and 1.5 (95% CI: 1.25-1.73) vs. men and young subjects. Among those with constipation, 16% (SK) to 40% (US) used laxatives. Laxative use was generally associated with increasing age, symptom frequency and lower income and education. A similar percentage of men and women with constipation reported using laxatives; a greater percentage of women used laxatives for a longer time. CONCLUSIONS: Prevalence of self-defined constipation and laxative use varies among countries. Prevalence is generally related to gender and age, whereas laxative use is related to age, but not to gender.
