Digestive symptoms are reported to result from a wide range of dietary components. Dietary pattern analysis is a useful method when considering the entire diet, rather than individual foods or nutrients, providing an opportunity to take interactions into account. The aim of the present study was to investigate, using a dietary pattern approach, the relationship between diet, digestive symptoms, and health-related quality of life (HRQoL) in women reporting minor digestive symptoms.
Analysis was performed on dietary and digestive symptoms data collected in France. Women (N = 308, ages 18-60 y) reporting a bowel movement frequency within the normal range (3-21 stools/wk) but with minor digestive symptoms in the previous month were studied. Dietary data was collected using three 24-h recalls. K-means was used to divide the dietary data into clusters. The frequency of digestive symptoms (abdominal discomfort or pain, bloating, flatulence, borborygmi) and bowel movements were evaluated over a 2-wk period. HRQoL was also assessed.
Four dietary clusters were identified and characterized as unhealthy, balance, healthy, and convenience. No differences were found in the frequency of digestive symptoms according to dietary cluster, except for flatulence (P = 0.030), which was more prevalent in the unhealthy and convenience clusters. No significant differences were observed in HRQoL according to dietary clusters.
Results from the present study demonstrated that even within a relatively homogeneous sample of French women, distinct dietary patterns can be identified but without significant differences in digestive symptoms (except for flatulence) or HRQoL.
据报道，消化症状由多种饮食成分引起。饮食模式分析是一种在考虑整体饮食而非单一食物或营养素时有用的方法，它提供了考虑相互作用的机会。本研究的目的是采用饮食模式方法，调查有轻微消化症状的女性的饮食、消化症状与健康相关生活质量（HRQoL）之间的关系。
对在法国收集的饮食和消化症状数据进行分析。研究对象为报告排便频率在正常范围（每周3 - 21次）但前一个月有轻微消化症状的女性（N = 308，年龄18 - 60岁）。使用三次24小时饮食回顾收集饮食数据。采用K均值法将饮食数据分为不同类别。在两周时间内评估消化症状（腹部不适或疼痛、腹胀、肠胃胀气、肠鸣音）和排便的频率。同时也评估了健康相关生活质量。
确定了四个饮食类别，分别为不健康、均衡、健康和便利型。除肠胃胀气外（P = 0.030），不同饮食类别在消化症状频率上未发现差异，肠胃胀气在不健康和便利型类别中更为普遍。不同饮食类别在健康相关生活质量方面未观察到显著差异。
本研究结果表明，即使在相对同质的法国女性样本中，也能识别出不同的饮食模式，但在消化症状（除肠胃胀气外）或健康相关生活质量方面没有显著差异。
