目的：了解年轻人的饮食模式及其与社会经济、人口和生活方式特征的关系。设计：基于人群的横断面队列研究分析。通过频率问卷评估食物摄入量，并使用主成分分析确定饮食模式。环境：巴西南部。对象：参加1982年Pelotas出生队列研究的4202名23岁的男性和女性。结果：确定了五种饮食模式：常见的巴西食品、加工食品、蔬菜/水果、乳制品/甜点和块茎/面食。那些自己或母亲受教育程度较低、社会地位较低或一生都很穷的研究对象对巴西常见饮食模式的依从性很高。相比之下，那些社会地位中高、从不贫穷的人更有可能遵循加工食品的模式。男性和吸烟者对加工食品和常见的巴西饮食模式有很高的依从性。女性和从事体育活动的人更有可能遵循蔬菜/水果模式。女性也表现出对乳制品/甜点模式的高度坚持。结论：我们对巴西年轻人的研究确定了明显受社会经济和生活方式特征影响的独特饮食模式，这在一个社会和经济不平等现象明显的国家具有重要的政策意义。
Objective: To identify dietary patterns among young adults and the relationships with socio-economic, demographic and lifestyle characteristics.Design: Population-based, cross-sectional analysis of a cohort study. Food intake was assessed by a frequency questionnaire, and dietary patterns were identified using principal components analysis.Setting: Southern Brazil.Subjects: A total of 4202 men and women aged 23 years, who participated in the 1982 Pelotas Birth Cohort Study.Results: Five dietary patterns were identified: common Brazilian, processed food, vegetable/fruit, dairy/dessert and tubers/pasta. Subjects who had low own or maternal educational levels, low social position or who were always poor throughout life had high adherence to the common Brazilian dietary pattern. In contrast, the processed food pattern was more likely to be followed by those belonging to middle and high social position and who were never poor. Men and smokers showed high adherence to the processed food and common Brazilian dietary patterns. Vegetable/fruit pattern was more likely to be followed by women and subjects engaged in physical activity. Women also showed high adherence to the dairy/dessert pattern.Conclusions: Our study among young Brazilian adults has identified distinct dietary patterns that are clearly influenced by socio-economic and lifestyle characteristics, which have important policy implications in a country with marked social and economic inequalities.
