“…Dietary Pattern Analysis: The Semi-Quantitative Food Frequency Questionnaire (SQFFQ) [ 26 ] was used to collect information on the frequency and consumption of various food by university students over the past six months. Through the pre-survey, we aimed to understand the most common food varieties eaten by university students; some of the same types of food varieties were clustered, and the 22 kinds of foods obtained formed the food list of the SQFFQ.…”

Functional constipation (FC) is prevalent worldwide and is an increasingly prominent problem among university students. However, there is a paucity of research on FC in university students. This study aimed to assess the prevalence of FC among Chinese university students by the Rome III criteria and investigate its associated factors. This cross-sectional study was conducted by online questionnaires among 929 university students at a Chinese university. Food consumption was assessed with the Semi-Quantitative Food Frequency Questionnaire (SQFFQ) and dietary patterns were analyzed using factor analysis. A binary logistic regression model was applied to clarify FC-associated factors. The prevalence of FC among university students was 5.1%. Interestingly, among university students, the prevalence of FC with “complex” dietary pattern was significantly higher than those with “vegetable, fruit, egg and milk-based” and “livestock and aquatic product-based” dietary pattern (9.9% vs. 3.1% vs. 2.8%, p < 0.001). The prevalence of FC was significantly higher among university students with moderate to severe sleep disorders than those with the other sleep status (χ2 = 18.100, p < 0.001). Furthermore, after adjusting the covariates, “complex” dietary pattern (OR = 4.023, p < 0.001), moderate to severe sleep disorders (OR = 3.003, p = 0.006), overeating (OR = 2.502, p = 0.032), long mealtime (>30 min) (OR = 6.001, p = 0.007), and poor defecation habits (OR = 3.069, p = 0.042) were positively associated with FC among university students. Based on the above-associated factors for FC, improving dietary patterns and sleep status and developing good bowel and dietary habits are essential to prevent and alleviate university students’ FC.

“…The types of dietary habits were distinguished based on the consumption of food items in the last year. Quantitative and qualitative data on dietary intake were assessed using a semi-quantitative food frequency questionnaire (SQFFQ) as previously described in our works [17]. The energy and nutrient intake of each participant was calculated based on the Chinese food composition tables [18].…”

Diet has a significant impact on fecal microbiota, which in turn plays an important role in human health. To evaluate the impact of dietary habits on fecal microbiota, we investigated the fecal microbial composition in vegetarians and omnivores using 16S rRNA gene sequencing, and estimated the correlation between fecal microbiota, body mass and diet. The dietary data showed that vegetarians consumed more plant-based foods rich in dietary fiber, omnivores consumed more animal-based foods rich in fat and overweight and obese people consumed more high-energy foods. Compared to omnivores, vegetarians had greater richness and diversity in their fecal microbiota. The Firmicutes/Bacteroidetes ratio was lower and the Prevotella/Bacteroides ratio was higher in vegetarians. The meat intake correlated positively with the proportion of Bacteroides and negatively with the proportion of Prevotella. The composition and diversity in fecal microbiota in the normal weight group, overweight group and obesity group were similar to that of vegetarians and omnivores, respectively. This paper revealed the distinctive characteristics of fecal microbiota in vegetarians and omnivores. The omnivorous diet contained more fat, which reduced the fecal microbial diversity, and was more likely to lead to being overweight or obese.
