Apple tote up period - trailing to the iOS Health app and launcheda clinical cogitation into char ’s healthback in 2019 . Now , the Apple Women ’s Health Study team has some preliminary data point that affirms that , yes , there is an unbelievable variety of period symptoms suffered by menstruating mass worldwide .
The determination were from the first 10,000 participant who enrolled in the report using the iPhone Research app and cater demographic data . Of that identification number , 6,141 participant recorded period symptom and the most commonly tracked were abdominal cramp ( 83 % ) , bloating ( 63 % ) , and tiredness ( 61 % ) . Or , basically , things anyone who ’s ever had a full point could order Doctor if they just involve . About half the participant also report acne , headaches , mood swings , appetite changes , lowly back pain sensation , and titty heart . Some rarer symptoms include diarrhea , sopor changes , impairment , sickness , blistering flashes , and ovulation pain .

One takeaway was that regardless of race , ethnicity , age , and geographic location , symptom absolute frequency was nearly universal . The participants report cramps , bloating , and tiredness as their most frequent symptom , and in similar number . So , you bonk , hard grounds that these symptom can affect any menstruating person .
These findings probably seem ludicrously obvious to anyone who is ever on a regular basis inspect by Aunt Flo . However , they also illustrate how current aesculapian research is woefully poor when it comes to women ’s health .
“ One of the most important things to remark is despite some of the advances in cycle - trailing dick that are useable , the inquiry in catamenial hertz and menstrual health remains limited , ” said Dr. Shruthi Mahalingaiah , a primary investigator on the survey and an adjunct professor at Harvard T.H. Chan School of Public Health . “ Historically , the menstrual cycle has been under - research , and women have been under - make up in very important , declamatory sketch . ”

For example , if you look for “ menstruation ” inPubMedbetween 2001 and 2018 , you only get some 8,400 studies on the subject . Conversely , a hunt during that same meter period for cardiovascular disease turns up 1.3 million consequence . If you want to get into sex - specific conditions , prostate cancer set about 121,000 results and cavernous dysfunction gets about 16,000 resultant . The problem get worse when you regard that most investigator , historically speak , have been men and excluded adult female from clinical inquiry . In the U.S. , Congress did n’t require women to be include in clinical trialsuntil 1993 . The result is a huge lack of foundational datum and poorer medical care for women . Take polycystic ovary syndrome , which impactsan calculate 5 million womenin the U.S. , piddle it one of the most common hormonal disorders among women of childbearing years — andless than halfare name correctly and 34 % with PCOS say it contract more thantwo year and three or more doctorsto receive a diagnosis . The numbers are even big for endometriosis , a painful condition that affects about 10 % of women andoften takes a decadeto be diagnosed . Not help matters is the general branding of talking about menstrual cycle per second , vagina , or uteruses at all .
This is a problem that wearables Lord are also shamefaced of . fittingness tracker have been around since 2011 , but it took Fitbit a whole seven years before it added cycle trailing . Garmin and Apple shortly followed , with the former also launchingpregnancy trackinglast November . However , Apple andAva , a birthrate tracker , are the only two that have thus far wage in clinical enquiry specifically around women ’s health .
So while the preliminary answer for the Apple Women ’s Health Study are n’t exactly head - blowing , it ’s a well matter this study even be . The voltage for clothing , which can capture long - terminal figure datum in a non - trespassing mode , to discover new selective information or run to more inquiry in fair sex ’s health is pretty dang gamey . When you view that any fair sex or menstruating person with an Apple Watch or iPhone could potentially participate in the work , you ’re look at a massive , diverse dataset that may start to help fix the egregious lack of foundational information in women ’s health .

“ What research worker and physician in the scientific residential area want and need to bang is more about the menstrual cycle , its sexual relation to prospicient - term health , as well as more about what environmental agent might affect cycle length and characteristic , ” Mahalingaiah say . “ With this study , we are creating a larger foundational data set on this topic , which can eventually lead to further discovery and innovation in womanhood ’s health inquiry and care . ”
