江苏省成年人体质肥胖变化10年纵向研究

摘要

背景：人群肥胖变化的纵向研究是探索病因的重要方法，可以为预防和控制肥胖提供科学依据。目的：通过年龄期间队列分析，阐明年龄、观察时期和出生队列对江苏省成年人肥胖率的影响。　　方法：以江苏省20-69岁的成年人为调查对象，采用分层整群抽样的方法，收集2000-2010年的肥胖数据，采用SAS软件分析资料。　　结果与结论：1946-1950年出生队列到1976-1980年出生队列的肥胖率在2000-2010年间逐渐上升(P <0.05)。而1931-1935年出生队列到1941-1945年出生队列等3个人群的肥胖率并没有明显增加(P>0.05)。25岁以上各年龄组随着年龄的增加，发生肥胖的危险性逐渐增大。25岁以上各组的OR值与20-25岁基准组相比差异均有显著性意义(P <0.05)。与1995-1999年相比，各观察时期的作用并不明显(P >0.05)。与1976-1980年出生队列相比，1951-1955年及其之后出生的各队列发生肥胖的危险性差别不明显(P>0.05)；但是从1946-1950年出生队列到1931-1935年出生队列发生肥胖的危险性则逐渐增强(P <0.05)，其中1936-1940年出生队列肥胖病的危险性最高(OR=2.93)。结果可见随着年龄的增加，发生肥胖的危险性逐渐增大；2000年以来的时代变迁对肥胖的影响并不明显；不同年代出生的人发生肥胖的危险性是有差异的；农村将是今后控制肥胖的重点地区，而控制肥胖过快增长的重点人群在45岁之前。%BACKGROUND:Longitudinal study of changes in obesity is an important method to explore the etiology, which can provide scientific basis for preventing and control ing obesity. OBJECTIVE:To investigate the effect of age, observation period and birth cohort on the obesity prevalence of adults in Jiangsu province through the age-period-cohort analysis. METHODS:20-69-year-old adults in Jiangsu province were col ected as the research objects. The stratified cluster sampling method was used to col ect the obese data in 2000-2010, and analyzed with SAS software. RESULTS AND CONCLUSION:Obesity prevalence of 1946-1950 birth cohort to 1976-1980 birth cohort was gradual y increased (P<0.05) from 2000 to 2010. Obesity prevalence from 1931-1935 birth cohort to 1941-1945 birth cohort was not significantly increased (P>0.05). With the increasing age in each age group of over 25 years old, the risk of obesity was increased gradual y. There were significant differences in the odds ratios between the baseline groups of 20-25 years old and the age groups of over 25 years (P<0.05). Compared with the 1995-1999 birth cohort, the other periods had a slight influence on the obesity prevalence (P>0.05). Compared with 1976-1980 birth cohort, there were no significant differences in the risks of obesity of the birth cohorts after 1951-1955 (P>0.05). But the risk of obesity from 1946-1950 birth cohort to 1931-1935 birth cohort was gradual y significant since the 2000;obesity risks of those born in the different times were different;rural area wil be the key area than 45 years old.
