Abstract
Taking Xigu District of Lanzhou City as an example, this paper systematically analyzes the spatio-temporal distribution characteristics of patients with chronic non-communicable diseases (NCD) and compares the differences between heating period and non-heating period. Furthermore, the impact paths of natural environmental factors and built-up environmental factors on NCD are probed with the help of the geographic detector. The results are as follows: In time, the incidence of NCD in Xigu district fluctuated from 2012 to 2019. In space, there was an overall declining trend in high incidence rate from the central area to the surrounding areas, among which Xigucheng street was the high-risk area. The incidence of NCD in heating period was higher than that of in non-heating period, and the number of H-H cluster areas was witnessed an obviously increasing growth in Sijiqing Street. There are significant differences in the explanatory power of different factors (if any) for NCD. The explanatory power of each index in Xigu District is as follows: Facility > SO2 > NO2 > PM2.5 > food > Beverage Service > Green Facilities > Traffic Regulations > medical facilities. The interaction between plant facilities and SO2 has the strongest effect on NCD. Except for the negative correlation between greening and medical facilities and the incidence of NCD, all the influencing factors were positively correlated with NCD.
Highlights
Accepted: 10 November 2021“Chronic disease” is short for noninfectious chronic disease (NCD) which refers to sort of complex non-communicable disease caused by genetic and environmental factors as well as by lifestyle [1]
With people putting more focus on health issue, many fields ramp up investments on related research and what factors are running behind chronic diseases has become a hot topic for scholars
[0, 1]; As h = 1, 2..., L is the stratification of variable Y or the factor X; In the formula, Nh and N refer to the number of h and that of units in the whole area, respectively; σh2 and σ2 refer to the variance of h and that of Y in the whole area, respectively; SSW and SST are the sums of the intra-stratal variance and the total variance of the whole area separately
Summary
“Chronic disease” is short for noninfectious chronic disease (NCD) which refers to sort of complex non-communicable disease caused by genetic and environmental factors as well as by lifestyle [1]. In heavy industrial areas, compared to the social environment, the natural environment and built environment play a important role in the health of urban residents, and they can induce diseases such as high blood pressure, heart trouble, and chronic obstructive pneumonia [28,29]. The selected heavy industry area can discuss the different research results of the special area and enrich the special case of the existing research, research into the built environment and natural environmental factors of chronic diseases can provide references for the prevention and control of NCD and the improvement of the health status of local residents
