To identify dietary patterns of a representative sample of Iranian adults using factor analysis.
This study was conducted in 2000-2001 as the baseline survey of Isfahan Healthy Heart Program (IHHP). We studied 12,514 participants aged ≥19 years who were randomly selected in three counties of Central Iran. A validated 48-item food frequency questionnaire was completed and factor analysis was used to identify dietary patterns.
Four major dietary patterns were identified, namely "Western", "animal fat", "traditional" and "Mediterranean". In both men and women, we found a significant positive relationship between age and Mediterranean diet, and a negative relationship between age and the other three dietary patterns (P < 0.001). The Western and traditional dietary patterns showed a significant negative relationship with education in both genders (P < 0.01). The Western dietary pattern correlated positively with being single, widowed, or a divorced man (P < 0.001).
We identified four major dietary patterns. As dietary pattern analysis is useful to identify dietary behaviors in relation to health risks, the results can be practical.
使用因子分析来确定伊朗成年人的饮食模式。
本研究于 2000-2001 年进行，作为伊斯法罕健康心脏计划（IHHP）的基线调查。我们研究了来自伊朗中部三个县的 12514 名年龄≥19 岁的随机选择的参与者。完成了一份经过验证的 48 项食物频率问卷，并使用因子分析来确定饮食模式。
在男性和女性中，我们发现地中海饮食与年龄呈显著正相关，而其他三种饮食模式与年龄呈显著负相关（P<0.001）。在两性中，西方和传统饮食模式与教育程度呈显著负相关（P<0.01）。西方饮食模式与单身、丧偶或离婚男性呈正相关（P<0.001）。
我们确定了四种主要的饮食模式。由于饮食模式分析有助于识别与健康风险相关的饮食行为，因此结果具有实际意义。
