摘要
目的 了解南京市30岁以上人群的膳食状况以及膳食模式与肥胖之间的关系,为政府制定干预措施提供科学依据.方法 采用多阶段随机整群抽样法,于2007年6-9月对南京市2个城区7个社区3 376名30岁以上常住居民进行调查.利用膳食平衡指数(diet balance index,DBI)构建膳食模式.结果 DBI总分(DBI_TS)平均值为-2.84±10.10,其中负端分(DBI_LBS)平均值为15.35±7.14,正端分(DBI_HBS)平均值为12.51±5.05,膳食质量距(DBI_DQD)平均值为27.86±7.15.9种DBI模式中D型模式所占比例最高(54.8％),且在性别、年龄、社会经济状况(SES)等方面差异均有统计学意义(P＜0.01).经多因素线性回归分析,体质指数(BMI)、腰围(WC)值平均每增加1个单位,DBI_DQD分别增加0.035、0.093.经单因素非条件logistic回归分析,与正常组相比,腹部并全身性肥胖组中非理想模式比例较高,OR=1.58(95％ CI=1.11～2.27,P＜0.05)；经多因素非条件logistic回归分析,差异亦有统计学意义(OR=1.57,95％ CI=1.09～2.25,P＜0.05).结论 肥胖与膳食模式之间存在相关,理想膳食模式对控制人群的肥胖有指导意义.
Abstract
Objective To identify and describe the major dietary patterns in the population older than 30 years in Nanjing City and their association with obesity. Methods With multi-stage cluster random sampling method, total 3 376 local residents aged 30 and over in 7 communities from 2 urban districts participated in the survey. Diet balance index (DBI) identified nine dietary patterns. Results The mean DBI_TS, DBI_LBS, DBI_HBS and DBI_DQD was -2.84±10.10, 15.35±7.14, 12.51±5.05 and 27.86± 7.15, respectively. D pattern was the highest proportion (54.8%) among all nine patterns. The nine patterns showed significant differences among gender, age groups and SES. By multiple linear regression, on average, 1 unit increase in BMI and WC was associated with 0.035 and 0.093 increase in DBI_DQD, respectively. By logistic regression, compared with the normal group, being neither general obesity (defined by BMI) nor abdominal obesity (defined by WC), group with both general obesity and abdominal obesity had the highest risk (OR=1.58, 95% CI= 1.11～2.27, P<0.05). After adjusted for possible confounding factors, there was also associated with significantly increased risk (OR=1.57, 95% CI=1.09～2.25, P<0.05). Conclusion The identified correlation between obesity and dietary pattern has an important guiding significance in controlling obesity.
