Intestinal transit rhythm and associated factors during the COVID-19 pandemic: A pilot study.

ABSTRACT

BACKGROUND & AIMS: Social distancing may lead to changes in lifestyle, such as the reduction in physical exercise practice, dietary changes, weight alterations, as well as intestinal rhythm. Our study aimed to investigate the intestinal transit rhythm of adults during social distancing due to the COVID-19 pandemic, in association with sociodemographic variables, physical activity, nutritional status, frequency of food intake, and water intake. METHODS: Our cross-sectional study comprised an online questionnaire that was shared by the internet concerning demographic information (sex and age); physical activity; anthropometric data (reported weight and height); dietary habits information (food frequency of simple high-carbohydrates foods, whole food, and processed foods; water intake; intestinal transit rhythm). The survey was conducted from April and July 2020. Statistical analysis was performed using Pearson's chi-square test (χ2) or Fisher's exact test, considering p < 0.05. RESULTS: During social distancing, 72.5% of the respondents presented an adequate intestinal transit rhythm, and 27.5% had inadequate intestinal transit rhythm (19.0% slow and 8.5% rapid intestinal transit rhythm). Intestinal transit rhythm differs between sex, with women presenting significantly higher odds for altered bowel rhythm, compared to men (OR (95% CI) = 2.324 (1.027-5.257); p = 0.043). Also, results showed that individuals who frequently ingest simple high carb foods have high prevalence of slow intestinal transit rhythm (63%, p = 0.032). CONCLUSION: In this study, we found a higher prevalence of adequate intestinal transit during social distancing due to the COVID-19 pandemic. Women had significantly higher odds for altered bowel rhythm, compared to men. Frequent consumption of simple carbohydrates was associated with a higher prevalence of slow intestinal transit rhythm.
