四川省30~79岁人群辣食摄入特征及与肥胖的关系

目的分析四川省彭州市成年人辣食摄入特征以及辣食与肥胖的关系,为慢性病预防控制和卫生决策提供科学依据。方法数据来源于中国慢性病前瞻性研究(China Kadoorie Biobank,CKB)项目四川省彭州市基线调查数据。于2004—2008年在四川省彭州市15个乡镇共完成55687名30~79岁常住居民的基线调查。调查内容包括问卷调查、体格测量和血样样本检测等内容,描述人群中辣食摄入、肥胖患病情况等。采用SAS 9.4和Excel 2013进行t检验、χ²检验和趋势χ²检验,采用非条件logistic回归分析辣食因素与肥胖的关系。结果彭州市人群辣食摄入率为77.66%,随年龄的增加呈递减趋势(P<0.05)。开始摄入辣食年龄为9.2岁,摄入时间以30~49年最多(64.36%)。同时摄入2种及以上辣食人群占97.51%。辣食摄入组肥胖患病率(8.56%)高于辣食非摄入组(7.25%),患病率随着辣食摄入频率增加呈上升趋势(P<0.05)。与不摄入辣食相比,女性和全人群辣食摄入与患肥胖高风险相关(OR值分别为1.24和1.19),均有统计学意义(P<0.05);而男性辣食摄入与患肥胖无关,无统计学意义(P>0.05)。女性和全人群每天或几乎每天摄入辣食(OR值分别为1.29和1.23),吃辣强度为中、高(女性OR值分别为1.11和1.38,全人群OR值分别为1.10和1.26),同时摄入辣食种类为5种(女性和全人群OR值分别为1.56和1.28)与患肥胖高风险相关,随着辣食摄入时间增加,OR值上升,50~59年组OR值最大(女性和全人群OR值分别为1.48和1.32),均有统计学意义(P<0.05)。结论四川省彭州市居民辣食摄入率较高,开始摄入辣食年龄小,摄入时间长,且以混合食用多种辣食为主。在总人群和女性中,辣食摄入频率、吃辣强度、摄入辣食种类与肥胖风险增加有关,在男性中未发现此种关联。
