Abstract

OBJECTIVE

To explore whether the association of community urbanization levels with overweight incidence changes over time and varies by region.

METHODS

The data is from the China Health and Nutrition Survey(1991-2015). The survey applied a multistage, random cluster design to draw samples. A total of 8684 adults aged 20-64 years were confined in nine provinces(autonomous regions). Based on an urbanicity score, communities were divided into two groups: low-and high-urbanization-level groups. The nine provinces(autonomous regions) were divided into four regions, including the Coast, Central, Northeast and West. Multilevel Logistic regression models was applied to examine whether the association between urbanization levels and overweight incidence changed over time and varied by region.

RESULTS

38.08% of respondents became overweight during the follow-up surveys. The interactions between the high urbanization level with the Coast(OR=0.45, 95%CI 0.34-0.60), the Central(OR=0.67, 95%CI 0.52-0.86), and the Northeast(OR=0.70, 95%CI 0.52-0.94) were statistically significant. The interaction between the high urbanization level and period was also statistically significant(OR=0.97, 95%CI 0.96-0.99). In 1991, the Coast(OR=0.99, 95%CI 0.77-1.26), the high urbanization level was positively associated with overweight incidence in the Central(OR=1.45, 95%CI 1.15-1.83), Northeast(OR=1.53, 95%CI 1.16-2.02) and West(OR=2.18, 95%CI 1.68-2.83), with statistical significance. In 2015, the high urbanization level was significantly negatively associated with overweight incidence in the Coast(OR=0.53, 95%CI 0.41-0.68) and Central(OR=0.77, 95%CI 0.62-0.97), while the association in the Northeast(OR=0.82, 95%CI 0.63-1.05) and West(OR=1.17, 95%CI 0.91-1.49) was statistically insignificant.

CONCLUSION

There were spatiotemporal variations in the association between urbanization levels and overweight incidence among adults in the nine provinces(autonomous regions).

摘要

目的

探讨社区城市化水平与超重发生率之间的关联是否随时间变化以及是否因地区而异。

方法

数据来自中国健康与营养调查（1991 - 2015年）。该调查采用多阶段随机整群抽样设计抽取样本。共有8684名20 - 64岁的成年人纳入九个省（自治区）。根据城市化得分，社区被分为两组：低城市化水平组和高城市化水平组。九个省（自治区）被分为四个地区，包括沿海、中部、东北和西部。应用多水平Logistic回归模型来检验城市化水平与超重发生率之间的关联是否随时间变化以及是否因地区而异。

结果

在随访调查期间，38.08%的受访者超重。高城市化水平与沿海地区（比值比[OR]=0.45，95%置信区间[CI] 0.34 - 0.60）、中部地区（OR = 0.67，95%CI 0.52 - 0.86）和东北地区（OR = 0.70，95%CI 0.52 - 0.94）之间的交互作用具有统计学意义。高城市化水平与时期之间的交互作用也具有统计学意义（OR = 0.97，95%CI 0.96 - 0.99）。1991年，在沿海地区（OR = 0.99，95%CI 0.77 - 1.26），高城市化水平与超重发生率呈正相关，在中部地区（OR = 1.45，95%CI 1.15 - 1.83）、东北地区（OR = 1.53，95%CI 1.16 - 2.02）和西部地区（OR = 2.18，95%CI 1.68 - 2.83）也呈正相关，具有统计学意义。2015年，高城市化水平与沿海地区（OR = 0.53，95%CI 0.41 - 0.68）和中部地区（OR = 0.77，95%CI 0.62 - 0.97）的超重发生率呈显著负相关，而在东北地区（OR = 0.82，95%CI 0.63 - 1.05）和西部地区（OR = 1.17，95%CI 0.91 - 1.49）的关联无统计学意义。
