Few studies appear to have investigated the prevalence of constipation for all three trimesters of the gestative period, or indeed after birth. Using a prospective 4- to 7-day weighed food diary, International Physical Activity Questionnaire and 7-day bowel habit diary, dietary factors, physical activity levels and bowel habit parameters were assessed and examined concurrently at weeks 13, 25, 35 of pregnancy and 6 weeks post-partum. Ninety-four primiparous pregnant women were initially recruited, and 72, 59, 62 and 55 completed the first, second, third trimester and post-partum study stages, respectively. Key dietary factors and physical activity levels were compared between the constipated and non-constipated groups from each of the three trimesters and after parturition. Compared with non-constipated mothers-to-be, constipated participants consumed statistically significantly less water in the first trimester (P = 0.04), more food in the second trimester (P = 0.04), and less iron (P = 0.02) and food (P = 0.04) in the third trimester and after birth, respectively. No statistically significant differences were identified between light, moderate and vigorous physical activity levels when groups were compared. This study demonstrates that dietary factors may play a role in terms of preventing, or alleviating, bowel habit perturbations both throughout and after pregnancy. Further research is required to investigate the interrelationship between physical activity and constipation during and after pregnancy.
似乎很少有研究调查整个妊娠期三个阶段以及产后便秘的患病率。通过使用一份为期4至7天的称重食物日记、国际体力活动问卷和为期7天的排便习惯日记，在妊娠第13周、25周、35周以及产后6周对饮食因素、体力活动水平和排便习惯参数进行了评估并同时进行了检查。最初招募了94名初产妇，分别有72名、59名、62名和55名完成了妊娠第一阶段、第二阶段、第三阶段和产后阶段的研究。比较了三个孕期和产后便秘组与非便秘组之间的关键饮食因素和体力活动水平。与非便秘的准妈妈相比，便秘参与者在孕早期摄入的水分显著减少（P = 0.04），在孕中期摄入的食物更多（P = 0.04），在孕晚期和产后分别摄入的铁（P = 0.02）和食物（P = 0.04）更少。比较不同组时，轻度、中度和剧烈体力活动水平之间未发现统计学上的显著差异。这项研究表明，饮食因素在预防或缓解孕期及产后排便习惯紊乱方面可能发挥作用。需要进一步研究来调查孕期和产后体力活动与便秘之间的相互关系。
