Associations between age, cohort, and urbanization with SBP and DBP in China: a population-based study across 18 years.

ABSTRACT: Little is known about whether large-scale environmental changes, such as those seen with urbanization, are differentially associated with SBP versus DBP, and whether those changes vary by birth cohort.We used data from the China Health and Nutrition Survey, a population-based cohort study of Chinese adults (n?=?18?754 aged 18-70 years), seen a maximum of seven times from 1991 to 2009. We used hierarchical multivariable linear models to simultaneously estimate SBP and DBP as correlated outcomes over time, accounting for their physiologic, time-varying correlation. Main exposure variables were urbanicity, age, and birth cohort. Over 18 years of modernization, median SBP and DBP increased by 10 and 7?mmHg, respectively.Our hierarchical model results suggest greater temporal increases in SBP and particularly DBP at lower versus higher urbanicity. At the same chronological age, for a 10-year difference in birth cohort (i.e. born in 1980s versus 1970s), the adjusted mean DBP was approximately 3?mmHg higher for the later birth cohort (P?

Project description:The coordinated development of land urbanization and population urbanization is crucial for the advancement of new urbanization. The study applied the entropy weight method and coupling coordination degree model, taking Shaanxi-a province in China characterized by a moderate pace of economic development and volume, along with distinct geographic and demographic features within its region-as the subject. It assessed the coordination conditions of these two types of urbanization from both macro and micro scales during the years 2010-2022. Utilizing the Analytic Network Process (ANP), the study ranked and analyzed the causes of issues stemming from uneven development, thus connecting a crucial link from theoretical analysis to decision-making implementation. The results showed that: (1) The province's land urbanization index was between 0.075 and 0.203, whereas the population urbanization index ranged from 0.221 to 0.408, with the development of the former significantly lagging behind the latter. (2) The coupling degree between land and population urbanization ranged from 0.835 to 0.854, with a coordination degree between 0.148 and 0.306. This indicated that a close connection had been formed between the two, yet a benign coupling relationship had not been established, displaying a spatial distribution characterized by "high in the middle, low in the north and south". (3) The limitation on further urban expansion was identified as the primary issue to be addressed (with a weight of 0.324), followed by insufficient infrastructure (with a weight of 0.261). The extent of ecological environmental damage was comparatively lower (with a weight of 0.225), and the degree of social injustice was the lowest (with a weight of 0.191). Therefore, to alleviate the problems associated with the imbalanced development between land urbanization and population urbanization, measures such as optimizing land spatial layout, enhancing urban ecological service functions, and strengthening the central cities' radiating effect should be implemented.
