In 2018 the first-year physiology class had a total of 229 students, whereas the 2019 physiology class had a total of 221 students. The transit time exercise took place in the first-year physiology laboratory as part of a first-year physiology laboratory exercise for 20 first-year cohorts. Therefore, the principal aim of this study was to demonstrate and record transit time in healthy first-year university students with whole-kernel sweetcorn. Cellulose is a dietary component that is thought to escape digestion in the human body, unlike in ruminants, because of the lack of cellulases in the human colon ( 7). Whole-kernel sweetcorn is composed mainly of cellulose in the outer shell (the yellowish hull) of the kernel. We planned a simple exercise using whole-kernel sweetcorn to measure student transit time.

Although this method was peculiar, it was a more convenient way for clinicians and researchers to determine gastrointestinal transit time, with the main concern being how to persuade participants to examine their own stool. The relationship between stool shape and gastrointestinal transit time was also validated by Lewis and Heaton ( 5), who showed that slow transit time resulted in constipation (i.e., characterized by hard, lumpy stool shapes). The importance of stool shape and consistency was demonstrated in a study ( 6) that showed a tendency for persons with slower transit times to have hard, lumpy stool shapes, whereas persons with faster transit times had looser, watery stool shapes.

Another proxy used to determine transit time is the Bristol stool chart, which describes the different types of stool shapes ( 5). The measurement of transit time is also dependent on the frequency of bowel movements as well as the structure of the ingested material ( 4). Transit time is measured by different techniques, including the ingestion of a substance that can be tracked as it travels along the gastrointestinal tract or is seen upon elimination from the body ( 3). There is, however, a lack of data regarding normal transit time, especially in southern Africa, with only a few studies ( 1, 2) conducted over four decades ago. Although this concept may seem trivial, it is a crucial concept for medical students and clinicians to understand so as to avoid misdiagnosis of atypical bowel movements. The common stated normal transit time is 24вЂ“48вЂ‰h, which is often misinterpreted as being the period between bowel movements.

However, the current literature publishes variable ranges of transit time. Clinicians reassure patients that a general range of five to seven times a week is normal. In clinical practice, patients often ask whether their own bowel movements are considered normal. Anxiety did impact the bowel activity of the participants. There were no differences between male and female student bowel activity. A wider range of transit time was reported in a group of young, healthy students compared with previous studies in the literature. Students who reported being worried and irritable during the exercise had more bowel movements before they saw corn in their stool and had slower transit times, respectively.

Likewise, there was no difference in the duration of the corn in the bowel between male and female students. There was no difference in gastrointestinal transit time between male and female students. The study analyzed responses of 175 students, who reported a median transit time of 29 (1вЂ“99) h. The secondary outcome was an association between emotional irritability and/or anxiety and gastrointestinal transit time. The primary outcome was the measurement of gastrointestinal transit time from the amount of time taken for ingested whole-kernel sweetcorn to be eliminated, which was calculated as the time period between ingestion of corn and the time of corn first seen in the stool and the time corn was last seen in the stool. All first-year health science students undertaking the Physiology course were invited to take part in the laboratory exercise.

The objective of this study was to determine gastrointestinal transit time in first-year health science students with a laboratory practical exercise conducted in two cohorts (classes of 20) of first-year health sciences students at the Health Science Campus in Windhoek, Namibia.
