The goal of this study was to determine whether dietary fat/fiber intake was associated with fecal incontinence (FI) severity.
Planned supplemental analysis of a randomized clinical trial evaluating the impact of 12-week treatment with percutaneous tibial nerve stimulation versus sham in reducing FI severity in women. All subjects completed a food screener questionnaire at baseline. FI severity was measured using the seven-item validated St. Mark's (Vaizey) FI severity scale. Participants also completed a 7-day bowel diary capturing the number of FI-free days, FI events, and bowel movements per week. Spearman's correlations were calculated between dietary, St. Mark's score, and bowel diary measures.
One hundred and eighty-six women were included in this analysis. Mean calories from fats were 32% (interquartile range [IQR] 30-35%). Mean dietary fiber intake was 13.9 ± 4.3 g. The percentage of calories from fats was at the higher end of recommended values, whereas fiber intake was lower than recommended for adult women (recommended values: calories from fat 20-35% and 22-28 g of fiber/day). There was no correlation between St. Mark's score and fat intake (r = 0.11, p = 0.14) or dietary fiber intake (r = -0.01, p = 0.90). There was a weak negative correlation between the number of FI-free days and total fat intake (r = -0.20, p = 0.008). Other correlations between dietary fat/fiber intake and bowel diary measures were negligible or nonsignificant.
Overall, in women with moderate to severe FI, there was no association between FI severity and dietary fat/fiber intake. Weak associations between FI frequency and fat intake may suggest a role for dietary assessment in the evaluation of women with FI.
本研究旨在确定饮食中的脂肪/纤维摄入量是否与粪便失禁（FI）的严重程度有关。
对一项评估为期 12 周经皮胫神经刺激治疗与假刺激治疗对女性 FI 严重程度影响的随机临床试验进行计划补充分析。所有受试者在基线时完成了食物筛选问卷。FI 严重程度使用经过验证的 St. Mark's（Vaizey）FI 严重程度量表的七项进行测量。参与者还完成了为期 7 天的排便日记，记录 FI 无失禁天数、FI 事件和每周排便次数。计算了饮食、St. Mark's 评分和排便日记测量值之间的 Spearman 相关系数。
本分析纳入了 186 名女性。脂肪提供的卡路里平均占 32%（四分位间距 [IQR] 30-35%）。膳食纤维摄入量平均为 13.9±4.3g。脂肪提供的卡路里百分比处于推荐值的较高端，而纤维摄入量低于成年女性的推荐值（推荐值：脂肪提供的卡路里 20-35%，膳食纤维 22-28g/天）。St. Mark's 评分与脂肪摄入量（r=0.11，p=0.14）或膳食纤维摄入量（r=-0.01，p=0.90）之间无相关性。FI 无失禁天数与总脂肪摄入量之间存在较弱的负相关（r=-0.20，p=0.008）。膳食纤维摄入量与排便日记测量值之间的其他相关性可忽略不计或无统计学意义。
总体而言，在中重度 FI 的女性中，FI 严重程度与饮食中的脂肪/纤维摄入量之间没有关联。FI 频率与脂肪摄入量之间的弱相关性可能表明饮食评估在 FI 女性的评估中具有作用。
