This study examined the relation between bowel-related symptoms and self-report of constipation in 10,875 subjects aged 60 years and over, who participated in the 1989 National Health Interview Survey. Subjects reporting constipation "always" or "mostly" over the past 12 months (n = 594) were compared with those who reported never having the symptom (n = 4,192). Straining (adjusted odds ratio 66.7; 95% confidence interval 31.5, 142.4) and hard bowel movements (25.6; 16.7, 38.7) were most strongly associated with self-report of constipation. These findings suggest that treatment for constipation in the older population should be directed as much or more at facilitating comfortable rectal evacuation, as increasing bowel movement frequency.
本研究调查了10875名60岁及以上参与1989年全国健康访谈调查的受试者中，肠道相关症状与便秘自我报告之间的关系。将在过去12个月中“总是”或“大部分时间”报告便秘的受试者（n = 594）与报告从未有过该症状的受试者（n = 4192）进行比较。用力排便（调整后的优势比为66.7；95%置信区间为31.5，142.4）和排便困难（25.6；16.7，38.7）与便秘自我报告的关联最为强烈。这些发现表明，老年人群便秘的治疗应更多地或至少同样多地致力于促进直肠舒适排空，而非仅仅增加排便频率。
