We hypothesized that dietary total fiber intake may be less than recommendations and that the intake of total, soluble, and insoluble fiber may be associated with demographic, lifestyle, and socioeconomic factors. Data were drawn from the Health Survey of São Paulo, a cross-sectional population-based study. Adolescents, adults, and elderly persons living in São Paulo city were included. Demographic, lifestyle, and anthropometric data were collected from households. Dietary intake was measured using two 24-hour dietary recalls. All analyses were conducted based on the sample design of the study. The proportion of individuals who met the adequate intake (AI) for total fiber intake was examined, and foods that contributed to the intake of fiber and fractions were evaluated. The relationship of total, soluble, and insoluble fiber intake with demographic, socioeconomic, and lifestyle characteristics was determined using multiple linear regression models. A low proportion of individuals met the AI for dietary fiber. The foods that most contributed to total fiber intake were beans, French bread, and rice. Total fiber intake was negatively associated with former and current smokers and positively associated with family income per capita and age. Soluble fiber intake was negatively associated with current smokers and positively associated with female sex, age, and family income per capita. Insoluble fiber intake was negatively associated with former or current smokers and positively associated with age. In summary, residents in the city of São Paulo had a low fiber intake, and demographic, socioeconomic, and lifestyle factors were associated with dietary fiber and intake of its fractions.
我们假设膳食总纤维摄入量可能低于推荐量，并且总纤维、可溶性纤维和不溶性纤维的摄入量可能与人口统计学、生活方式和社会经济因素有关。数据来自圣保罗健康调查，这是一项基于人群的横断面研究。纳入了居住在圣保罗市的青少年、成年人和老年人。从家庭中收集人口统计学、生活方式和人体测量数据。使用两次24小时膳食回顾来测量膳食摄入量。所有分析均基于该研究的样本设计进行。检查了达到总纤维摄入量适宜摄入量（AI）的个体比例，并评估了对纤维及其组分摄入量有贡献的食物。使用多元线性回归模型确定总纤维、可溶性纤维和不溶性纤维摄入量与人口统计学、社会经济和生活方式特征之间的关系。达到膳食纤维AI的个体比例较低。对总纤维摄入量贡献最大的食物是豆类、法式面包和大米。总纤维摄入量与既往吸烟者和当前吸烟者呈负相关，与人均家庭收入和年龄呈正相关。可溶性纤维摄入量与当前吸烟者呈负相关，与女性、年龄和人均家庭收入呈正相关。不溶性纤维摄入量与既往或当前吸烟者呈负相关，与年龄呈正相关。总之，圣保罗市居民的纤维摄入量较低，人口统计学、社会经济和生活方式因素与膳食纤维及其组分的摄入量有关。
