This study aimed to identify dietary patterns and assess their association with abdominal fat. A cross-sectional study was conducted in the Central West Region of Brazil with a probabilistic sample of 208 adults of both sexes. Data on food intake was obtained using a food frequency questionnaire and factor analysis (principal components) was conducted to identify dietary patterns. Waist circumference (WC) and waist-to-hip ratio (WHR) were used to assess abdominal fat. The association between dietary patterns and body fat distribution was examined using multiple linear regression analysis adjusted for confounders. Three dietary patterns were identified: Western, regional traditional, and prudent. A positive association was found between the Western pattern and WC (p = 0.04) and WHR (p = 0.001) and between the regional traditional pattern and WHR (p = 0.05) among women. A slight association was also found between the latter pattern and WC (p = 0.07) also among women. An association was found between the Western and regional traditional dietary patterns and a larger concentration of abdominal fat among women.
本研究旨在确定饮食模式，并评估其与腹部脂肪的相关性。这是一项在巴西中西部地区进行的横断面研究，采用概率抽样方法，选取了 208 名男女成年人作为研究对象。通过食物频率问卷获取了关于食物摄入的数据，并采用因子分析（主成分分析）来确定饮食模式。使用腰围（WC）和腰臀比（WHR）来评估腹部脂肪。通过多线性回归分析调整混杂因素后，研究了饮食模式与体脂分布之间的关联。确定了三种饮食模式：西方模式、区域传统模式和谨慎模式。研究发现，在女性中，西方模式与 WC（p=0.04）和 WHR（p=0.001）呈正相关，区域传统模式与 WHR（p=0.05）呈正相关。此外，还发现后者与 WC （p=0.07）也呈轻微正相关。研究发现，在女性中，西方和区域传统的饮食模式与腹部脂肪的堆积有关。
