To evaluate the prevalence and associated factors of childhood constipation in Taiwan.
Healthy children between 7 and 12 years of age were interviewed to determine the prevalence of constipation and associated demographic and dietary factors. A nationwide sample of 2,375 children was selected with complex multistaged sampling throughout Taiwan.
In total, 2,375 individuals (1,282 boys and 1,093 girls, mean age=9.3±2.2 years) were interviewed, with a response rate of 95.1%. The prevalence of constipation was 32.2%, and girls were more likely to have constipation than boys (36.1% vs. 29.2%, p=0.0012) in this study. The prevalence of constipation was inversely related to age (24.4% for children aged 11 and 12, 34.0% for children aged 9 and 10, and 39.6% for children aged 7 and 8, p<0.001). Constipated children were more likely to report irregular bowl movements (37.2% vs. 29.3%, p=0.003), and constipated children had a significantly lower body mass index (17.5kg/m(2)vs. 18.3kg/m(2), p<0.001). The dietary intake for children with constipation was associated with lower intake of vegetables (4.2 servings/week vs. 5.8 servings/week, p<0.05), fruits (5.6 servings/week vs. 7.0 servings/week, p<0.05), soybean products (2.2 servings/week vs. 2.9 serving/week, p<0.05), and eggs (3.9 servings/week vs. 4.6 servings/week, p<0.05).
Constipation is common in Taiwanese school-aged children, especially in girls. Less frequent consumption of vegetables, fruits, soybean products, and eggs is associated with childhood constipation. Establishing a regular bowel habit is encouraged to decrease the risk of constipation, and allowing the children a relaxed and sufficient time to defecate after school is essential.
评估台湾地区儿童便秘的患病率及其相关因素。
对 7 至 12 岁健康儿童进行访谈，以确定便秘的患病率以及相关的人口统计学和饮食因素。通过在台湾全省采用复杂的多阶段抽样，抽取了 2375 名儿童进行全国性抽样调查。
共对 2375 名儿童（1282 名男孩和 1093 名女孩，平均年龄=9.3±2.2 岁）进行了访谈，应答率为 95.1%。本研究中，便秘的患病率为 32.2%，女孩便秘的发生率高于男孩（36.1%比 29.2%，p=0.0012）。便秘的患病率与年龄呈负相关（7-8 岁儿童为 39.6%，9-10 岁儿童为 34.0%，11-12 岁儿童为 24.4%，p<0.001）。便秘儿童更有可能报告排便不规则（37.2%比 29.3%，p=0.003），且其体质指数明显较低（17.5kg/m2比 18.3kg/m2，p<0.001）。便秘儿童的饮食摄入与蔬菜（4.2 份/周比 5.8 份/周，p<0.05）、水果（5.6 份/周比 7.0 份/周，p<0.05）、大豆制品（2.2 份/周比 2.9 份/周，p<0.05）和鸡蛋（3.9 份/周比 4.6 份/周，p<0.05）的摄入量较低有关。
台湾地区学龄儿童便秘较为常见，尤其是女孩。蔬菜、水果、大豆制品和鸡蛋摄入较少与儿童便秘有关。鼓励养成规律的排便习惯，以降低便秘的风险，此外，让孩子放学后有放松和充足的时间排便也很重要。
