In contrast to the US and Europe, prevalence and laxative use for self-defined constipation among adults was previously reported to be unassociated with age among adults in South Korea and Brazil.
To determine whether observations in South Korea and Brazil are reflective of other Asian and South American countries.
A total of 8100 adults from Argentina, Colombia, Indonesia and China completed a questionnaire identical to that previously used in South Korea and Brazil.
Prevalence of constipation was similar to that reported for Brazil and South Korea and was 2.17-fold (95% CI: 1.71-2.64) higher amongst women than amongst men. Prevalence increased with age amongst all adults in Argentina and China and only among men in Colombia and Brazil. With the exception of Indonesia, the majority of those with constipation had symptoms at least once weekly, and for < or =3 years. Less than one-third of adults reported using laxatives to treat constipation. Laxative use was not associated with gender and increased with age in Argentina and Colombia.
No clear geographical or cultural tendencies were observed in the prevalence of constipation and laxative use among the South American and Asian countries studied in this survey.
与美国和欧洲不同，此前有报道称，在韩国和巴西，成年人中自我定义的便秘的患病率和泻药使用与年龄无关。
确定韩国和巴西的观察结果是否反映了其他亚洲和南美洲国家的情况。
来自阿根廷、哥伦比亚、印度尼西亚和中国的共 8100 名成年人完成了一份与之前在韩国和巴西使用的问卷完全相同的问卷。
便秘的患病率与巴西和韩国的报告相似，女性比男性高 2.17 倍（95%CI：1.71-2.64）。在阿根廷和中国的所有成年人中，患病率随年龄增长而增加，而在哥伦比亚和巴西，仅在男性中增加。除印度尼西亚外，大多数便秘患者每周至少有一次症状，持续时间<或=3 年。不到三分之一的成年人报告使用泻药治疗便秘。在阿根廷和哥伦比亚，泻药的使用与性别无关，且随年龄增长而增加。
在本调查中研究的南美洲和亚洲国家中，没有观察到便秘和泻药使用的明显地理或文化倾向。
