To identify somatic complaints dimensions, classify studied population and study the association of demographic and lifestyle factors with somatic complaints dimensions.
In a cross-sectional study conducted on 4763 Iranian adults, somatic complaints were assessed using a comprehensive 30-item questionnaire. Self-administered standard questionnaires were used to assess demographic and lifestyle factors. Factor mixture modeling (FMM) was used to identify somatic complaints dimensions and classify studied population.
The mean age of participants was 36.58 ± 0.13 years, 55.8% were females, 81.2% were married, and 57.2% had college education. About 9.4% of individuals were obese, and 34.8% of participants had regular physical activity. Four domains of somatic complaints were extracted, including "psychological," "gastrointestinal," "neuro-skeletal," and "pharyngeal-respiratory." Females, obese and inactive participants, and those in low educations had significantly greater scores in terms of four domains than the others ( < 0.05). A two-class, four-factor structure fitted to the somatic complaints based on FMM. Two classes were labeled "high psychological complaints" (519 individuals (11%) and "low psychological complaints" (4243 individuals (89%). There were no significant differences between two classes in terms of demographic and lifestyle factors, except in educational level.
This study suggested that somatic complaints had a dimensional-categorical structure within studied population so that it could be useful for dealing with diagnostic and therapeutic approaches. The results did not show any association between somatic complaints dimensions and demographic, lifestyle factors, except in educational level.
确定躯体主诉维度，对研究人群进行分类，并研究人口统计学和生活方式因素与躯体主诉维度之间的关联。
在一项对4763名伊朗成年人进行的横断面研究中，使用一份包含30个项目的综合问卷评估躯体主诉。采用自行填写的标准问卷评估人口统计学和生活方式因素。使用因子混合模型（FMM）确定躯体主诉维度并对研究人群进行分类。
参与者的平均年龄为36.58±0.13岁，55.8%为女性，81.2%已婚，57.2%拥有大学学历。约9.4%的个体肥胖，34.8%的参与者有规律的体育活动。提取了躯体主诉的四个领域，包括“心理”、“胃肠道”、“神经骨骼”和“咽喉-呼吸”。女性、肥胖且不活动的参与者以及低学历者在这四个领域的得分显著高于其他人（<0.05）。基于FMM，一种两类四因素结构适合躯体主诉。两类分别标记为“高心理主诉”（519人（11%））和“低心理主诉”（4243人（89%））。除教育水平外，两类在人口统计学和生活方式因素方面没有显著差异。
本研究表明，在研究人群中躯体主诉具有维度-分类结构，因此对处理诊断和治疗方法可能有用。结果显示，除教育水平外，躯体主诉维度与人口统计学、生活方式因素之间没有任何关联。
