BackgroundCharacterizing and assessing the prevalence, awareness, and treatment patterns of patients with isolated diastolic hypertension (IDH) can generate new knowledge and highlight opportunities to improve their care.Methods and ResultsWe used data from the China PEACE (Patient‐centered Evaluative Assessment of Cardiac Events) Million Persons Project, which screened 2 351 035 participants aged 35 to 75 years between 2014 and 2018. IDH was defined as systolic and diastolic blood pressure of <140 and ≥90 mm Hg; awareness as self‐reported diagnosis of hypertension; and treatment as current use of antihypertensive medications. Of the 2 310 184 participants included (mean age 55.7 years; 59.5% women); 73 279 (3.2%) had IDH, of whom 63 112 (86.1%) were untreated, and only 6512 (10.3%) of the untreated were aware of having hypertension. When compared with normotensives, participants who were <60 years, men, at least college educated, had body mass index of >28 kg/m2, consumed alcohol, had diabetes mellitus, and prior cardiovascular events were more likely to have IDH (all P<0.01). Among those with IDH, higher likelihood of awareness was associated with increased age, women, college education, body mass index of >28 kg/m2, higher income, diabetes mellitus, prior cardiovascular events, and Central or Eastern region (all P<0.05). Most treated participants with IDH reported taking only 1 class of antihypertensive medication.Conclusions IDH affects a substantial number of people in China, however, few are aware of having hypertension and most treated participants are poorly managed, which suggests the need to improve the diagnosis and treatment of people with IDH.

The origin, quantities distribution and different market positioning of steamed dishes stores in Wuhan were analyzed based on the big data of Meituan application. By April 2020, there were a total of 230 steamed dishes restaurants in Wuhan, mainly distributed in Hongshan district (63), Jianghan district (47) and Wuchang district (35). Now the largest steamed dishes restaurant chains was "Zhen Kungfu" originated from Cantonese cuisine while "Liuyang steamed dishes” and "Zhen Liuji" restaurants were in the second place which came from "Home of steamed dishes in China". All of them were rapidly expanding in the form of Chinese fast-food chains in recent years and located either near the business district or the airport/station. On the contrary, "Mianyang three streamed dishes" restaurants with regional characteristics was few and scattered. It had not yet formed a scale with its unclear product positioning. A survey of consumers' preference showed that about 22% of consumers chose steamed dishes when eating out. With the increase of age, more and more people would opt for steamed dishes. Half of consumers over 40 chose steamed dishes. On the other hand, there were double peaked at 20 Yuan and 45 Yuan per person in consumers’ psychological prices. These results would provide reference for the development of "Mianyang three streamed dishes" and Wuhan catering economy.
