摘要:
目的 了解上海市普陀区居民食物摄入频率现状和膳食结构模式,为今后开展营养教育和营养改善工作提供科学依据。 方法 选用2007年上海市普陀区居民营养与健康状况的调查资料,运用食物摄入频率法调查1277名15岁及以上居民,对每位调查对象过去1年的各类食物摄入频率和摄入量进行询问并记录。采用评分方法评价该区居民的膳食质量,采用多元线性回归分析方法筛选食物摄入频率的相关影响因素。 结果 普陀区居民谷类、蔬菜类、水果类、鱼虾类摄入频率较高,得分均在3分以上,畜禽肉类、蛋类、豆类和奶类次之。但蔬菜、水果以及奶类的摄入量与国家推荐标准相比仍有较大差距,居民的膳食结构仍不太合理。影响居民食物摄入频率的主要影响因素是经济状况(P=0.00)、文化程度(P<0.05)、性别(P=0.00)和职业(P<0.05)。 结论 目前普陀区居民的膳食状况以蔬菜、水果和奶类的摄入不足为主要问题,应加强营养知识的宣传教育,引导合理膳食。 Abstract:Objective To investigate the dietary pattern of residents in Putuo district, Shanghai and provide basic information for nutrition improvement.
