【目的】了解6岁以下儿童的排便状况。【方法】将2009年12月-2010年3月重庆医科大学儿童医院儿保科体检的6岁以下和部分幼儿园儿童作为调查对象。采用婴幼儿(0～2岁)及年长儿(2.1～6岁)两种问卷调查儿童的大便情况。【结果】90%以上1岁儿童排便次数(1次或2次/日)与性状接近成人。近2/5的婴儿排大便已定时(77/207,占37.2%),其中90.9%(70/77)6月龄前大便时间已较固定。503例6岁以下儿童中发生便秘者57例(11.3%),近3/5(59.6%)发生便秘的儿童中排便次数为1次/日。【结论】儿童排便状况与年龄有关。大便次数不是诊断便秘的主要依据。
【Purpose】 To understand the defecation status of children under 6 years old. 【Methods】 The subjects under 6 years of age and some kindergarten children underwent physical examination in Children’s Hospital of Chongqing Medical University from December 2009 to March 2010 were investigated. Children’s stools were investigated using two questionnaires: infants (0-2 years old) and older children (2.1-6 years old). 【Results】 The defecation frequency (1 or 2 times / day) in 90% of children aged 1 year was close to that of adult. Nearly two-fifths of infants had bowel movements stamped (77/207, 37.2%), of which 90.9% (70/77) had poorer stools before 6 months of age. 57 cases (11.3%) of 503 cases of constipation occurred in children under 6 years of age, and nearly 3/5 (59.6%) cases of constipation in children with defecation frequency of 1 / day. 【Conclusion】 Childhood defecation is related to age. Stool frequency is not the main basis for the diagnosis of constipation.
