New groundbreaking medical research published in JAMA

The Journal of the American Medical Association (JAMA), the leading US medical publication, published a new research paper.
While the study was conducted on the Australian population, the results could be widely applied to the US population as well.
Below, I will quote the most important parts of the research.
Regular Flatulence Patterns Among Community-Dwelling Individuals in Australia [jamanetwork.com]
To summarize, the data shows a suspiciously low number of farts (at least in my experience) with an average of only 5 farts per day, with females reported less farts than males, with the lowest farting reported between 10 AM and 1 PM, and surprisingly, the older population farting far less than ages 26-45.

Methods Data were recorded into a purpose-designed mobile phone application (Chart Your Fart) by participants who logged their flatus passages in real time, consistent with experience sampling methods.3 Participants were recruited using nonprobability sampling methods and invited to take part through a large national communication campaign targeting various audiences and media. Results The sample mean was 5.0 fls/d (SD, 3.8 fls/d), with a median of 3.8 fls/d (IQR, 2.5-6.2 fls/d); 5085 (79.3%) recorded between 2 and 7 fls/d. Males recorded higher activity than females. The youngest age group reported fewer daily releases compared with all other age groups. Across-day variation showed a gradual increase with a peak between 6 and 10 pm (Figure). This overlapped with general population total energy and fiber intake,5 with a notable dip in flatulence recordings in the middle of the day. Discussion Our data are, to our knowledge, the first to describe real-time flatulence habits in a large, general population. In terms of range, observed data suggest good consistency with other methods, including retrospective frequency reports in a large US sample of individuals experiencing gas or bloating (n = 16 537),6 a small laboratory study that collected a median of 8 emissions throughout 24 hours,7 and even Benjamin Franklin's personal account of "discharging wind from bowels" 7 times a day.8 One small sample (n = 25) using a physical diary recorded higher mean rates over 1 week (10 fls/d).9 Differences across age groups were also consistent with a previous report. |
