To describe the association of socio-economic, demographic and lifestyle characteristics with three eating patterns identified among low-income adults living in the Rio de Janeiro metropolitan area, Brazil.
Data were obtained in a population-based cross-sectional study. The analysed patterns were: (i) 'Mixed', in which diverse foods had similar factor loadings; (ii) 'Western', which included items with high energy density; and (iii) 'Traditional', which relied in rice and beans, traditional staple foods in Brazil. Hierarchical logistic analysis was performed to estimate the association between the independent variables and each one of the dietary patterns. The variables that presented statistical significance <0·20 in the univariate analysis (χ2 test) were included in the multivariate models.
Duque de Caxias, a low-income area in the Rio de Janeiro metropolitan region, Brazil.
Adults (n 1009) aged 20 to 65 years (339 men and 670 women).
The 'Mixed' pattern was positively associated with smoking (OR = 1·58, 95 % CI 1·00, 2·48 for current smoking v. those who never smoked). The 'Western' pattern was positively associated with family income (OR = 3·00, 95 % CI 1·81, 4·97 for those with monthly per capita family income ≥1·0 v. <0·5 times the official Brazilian minimum wage) and inversely associated with family food insecurity (OR = 0·55, 95 % CI 0·36, 0·84). The 'Traditional' pattern was associated with family food insecurity (OR = 1·79, 95 % CI 1·27, 2·51).
The results support previous findings relating improvement in economic conditions to reduced adherence to the traditional Brazilian food consumption pattern based on the combination of rice and beans.
描述巴西里约热内卢大都市区低收入成年人中三种饮食模式与社会经济、人口统计学和生活方式特征的关联。
本研究为基于人群的横断面研究。分析的模式为：（i）“混合”，其中各种食物具有相似的因子负荷；（ii）“西方”，包括高能量密度的项目；（iii）“传统”，依赖于大米和豆类，巴西的传统主食。进行分层逻辑回归分析以估计独立变量与每种饮食模式之间的关联。在单变量分析（卡方检验）中具有统计学意义（<0·20）的变量被纳入多变量模型。
巴西里约热内卢大都市区的贫困地区 Duque de Caxias。
年龄在 20 至 65 岁之间的成年人（n 1009）（339 名男性和 670 名女性）。
“混合”模式与吸烟呈正相关（当前吸烟者与从不吸烟者相比，OR = 1·58，95 % CI 1·00，2·48）。“西方”模式与家庭收入呈正相关（与每月人均家庭收入≥1·0 倍官方巴西最低工资相比，<0·5 倍的家庭，OR = 3·00，95 % CI 1·81，4·97），与家庭食物不安全呈负相关（OR = 0·55，95 % CI 0·36，0·84）。“传统”模式与家庭食物不安全有关（OR = 1·79，95 % CI 1·27，2·51）。
这些结果支持了先前的发现，即经济条件的改善与减少对以大米和豆类为基础的传统巴西食物消费模式的坚持有关。
