All authors read and approved the final manuscript.Digestive symptoms are reported to result from a wide range of dietary components. Dietary 4 pattern analysis is a useful method of considering the entire diet, rather than individual foods or 5 nutrients, providing an opportunity to take interactions into account. The objective was to 6 investigate the relationship between diet, digestive symptoms and health-related quality of life 7 (HRQoL) in women reporting minor digestive symptoms, using a dietary pattern approach. 8 9 Research methods 10Analysis was performed on dietary and digestive symptoms data collected in France. Females 11 (n=308, aged 18-60yrs) reporting a bowel movement frequency within the normal range (3-21 12 stools/week) but with minor digestive symptoms in the previous month were investigated. 13Dietary data was collected using three 24-hr recalls. K-means was used to divide the dietary data 14 into clusters. The frequency of digestive symptoms (abdominal discomfort or pain, bloating, 15 flatulence, borborygmi) and bowel movements were evaluated over a two week period. HRQoL 16 was also assessed. Our results demonstrate that even within a relatively homogeneous sample of French women, 27 distinct dietary patterns can be identified but without significant differences in digestive 28 symptoms (except for flatulence), and HRQoL. 29

A systematic review of the association between dietary patterns and health-related quality of life

“…), "Nordic", or "French" diets and HRQOL. In summary among thirteen included studies, ten studies found significant relations between dietary patterns (dietary patterns derived with factor or cluster analysis or MDP) and HRQOL while three studies did not observe any significant relations between dietary patterns and HRQOL [21][22][23]. Because of the great heterogeneity between the methodological approaches, study designs and report of results, the data synthesis and meta-analysis was not possible.…”

“…The studies were performed 10 years apart and both the studies used different methods to measure dietary pattern and HRQOL, and found consistent findings. In a cross sectional study by Holmes et al [22]; it was noted that no significant differences in HRQOL were found between dietary patterns. They used cluster analysis to derive dietary patterns and FBA questionnaire for assessment of HRQOL.…”

“…In the current systematic review, the studies reporting the relationship between dietary patterns and HRQOL were reviewed. Most of the included studies showed the relationship between dietary patterns and HRQOL with only three exceptions showing no association in subjects with minor digestive problems and type1 diabetes [21][22][23]. Of the studies evaluating the dietary patterns reported higher adherence to healthy dietary patterns are associated with better scores of HRQOL in one or more dimensions [17,27,28,46,47].…”

“…Few studies have examined the relationship between dietary patterns and HRQOL and their results are inconsistent and the majority of the studies in literature have been limited by cross-sectional study design. For example, studies by Mozzillo et al [ 21 ], Holmes et al [ 22 ] and Perez-Tasigchana et al (UAM-cohort) [ 23 ] have not found any significant relationship between dietary patterns and HRQOL. However, some studies have reported the association of namely "Western" or "Unhealthy" dietary patterns with physical and mental chronic disease [ 24 – 26 ] and poor HRQOL [ 17 , 27 , 28 ].…”

Western Dietary Pattern Is Associated with Irritable Bowel Syndrome in the French NutriNet Cohort

“…The authors also identified a western profile, which showed no association with IBS in neither women nor men. A study performed recently in France among 380 women showed that the dietary clusters “unhealthy” and “convenience” were associated with a higher frequency of flatulence [ 45 ]. Despite some differences, the “fast-food” profile identified by Khayyatzadeh and colleagues, and the “unhealthy” cluster of Holmes and colleagues have common features with our “western” DP, especially regarding the higher amount of fats and carbohydrates intake.…”
