This research, led by Academician Ning Guang and completed by the team of Ruijin Hospital affiliated to Shanghai Jiaotong University, is the first large-scale use of passive data on the Internet in China to explore the relationship between people's living habits and diseases.
Compared with the past cohort studies using questionnaires and self-reports, the data on the Internet are more objective and accurately reflect the health differences caused by different cooking and taste preferences in different regions of China. There are more hypertension, diabetes and high body mass index (BMI) in areas that love high-temperature cooking, and the risk of diabetes is lower in areas that love spicy food.
More than 200 million people! Where did such a large amount of data come from?
In this study, the data of Baidu search engine and take-away platform for 20 16 years were used, and the total number of participants was 2 1234 1708 (more than 213.34 million). Most of the users included are adults under the age of 45, and the total data is younger, but the data of 65 years old exceeds 400,000, and the researchers corrected the age in the analysis.
"Baidu" doesn't sound very reliable?
It must be explained here that this study finally compared the disease conclusions calculated from this network data with the national epidemiological survey data from 20 10 to 20 13, and the results showed no significant difference.
Generally speaking, these data samples provided by Baidu are consistent with the medical observation results.
(There is no significant difference between the incidence of diabetes and hypertension predicted by Internet data and the data of body mass index and epidemiological survey. )
This study not only analyzes the different cooking styles and tastes in different regions of the country, but also analyzes the relationship between these tendencies and latitude, temperature and economic development.
These areas love unhealthy cooking! Did you confess at home?
The analysis shows that the areas that like to eat fried barbecue are concentrated in the high latitudes around Beijing and northeast China, as shown in the following two pictures. The darker the color, the more target food is consumed in this area.
The area of barbecue is concentrated in the high latitude areas around Beijing and northeast China.
On the issue of barbecue, Hainan Province is a special case in the south, and its love for barbecue is no less than that in the northeast, but its love for fried food is not outstanding. In addition, although Guangdong is not as delicious as Beijing, it also shows the love of frying and barbecue.
In terms of temperature, fried food is more attractive to residents in colder places in winter. From an economic point of view, researchers have observed that the popularity of barbecue is directly proportional to the improvement of economic level.
Disease prediction and actual observation data analysis show that the preference for frying and barbecue will lead to high body mass index, high incidence of hypertension and diabetes. This triple whammy only occurs in fried and grilled foods.
