BACKGROUND
Understanding the association between psychological affective disturbances and anthropometric parameters, including body mass index (BMI), is important. These issues may have potential preventive effects on weight reduction in relation to different aspects of women's lifestyles and psychopathological states. The present study aimed to predict BMI based on psychological factors including; depression, anxiety, dietary restraint, and nutritional habits, in a sample of women with sedentary jobs in several Iranian governmental organizations.
METHODS
Two hundred consecutive women aged over 25 years, working on sedentary or low standing works such as banker, teachers, and employee in the social security organizations in Isfahan, Iran, were entered the study. To assess the severity of depression and anxiety symptoms, the Beck Depression Inventory II and the State-Trait Anxiety Inventory were used, respectively. To assess nutritional habits, a self-administered questionnaire was designed, and to evaluate dietary restraint status, the Ruderman questionnaire was used. To find the co-relationship between BMI and each of the psychological components, Pearson's correlation coefficient test was applied.
RESULTS
To assess the relationship between BMI and each of the psychological components, a multivariate regression model was used. Only two components of nutritional habits (b = -0.19, < 0.001) and dietary restraint (b = 0.51, < 0.001) could effectively predict BMI in Iranian women; while depression and anxiety components had low predictive values for predicting BMI. In total, these four variables could predict 34% of the variance of the dependent indicator (BMI).
CONCLUSION
Nutritional habits and dietary restraint have high value for predicting BMI status in women aged more than 25 years working in sedentary jobs, while BMI status could not be predicted by assessing depression or anxiety severity.
背景
了解心理情感障碍与人体测量参数（包括体重指数（BMI））之间的关联非常重要。这些问题可能会对与女性生活方式和精神病理状态不同方面相关的体重减轻产生潜在的预防作用。本研究旨在基于包括抑郁、焦虑、饮食限制和营养习惯等心理因素，对伊朗几个政府组织中从事久坐工作的女性样本的BMI进行预测。
方法
连续纳入200名年龄超过25岁、从事久坐或低站立工作（如银行职员、教师以及伊朗伊斯法罕社会保障组织的员工）的女性参与研究。分别使用贝克抑郁量表第二版和状态-特质焦虑量表评估抑郁和焦虑症状的严重程度。设计了一份自填式问卷来评估营养习惯，并使用鲁德曼问卷评估饮食限制状况。为了找出BMI与每个心理成分之间的相互关系，应用了皮尔逊相关系数检验。
结果
为了评估BMI与每个心理成分之间的关系，使用了多元回归模型。在伊朗女性中仅营养习惯（b = -0.19，<0.001）和饮食限制（b = 0.51，<0.001）这两个成分能够有效预测BMI；而抑郁和焦虑成分对BMI的预测价值较低。总体而言，这四个变量能够预测34%的因变量（BMI）方差。
结论
营养习惯和饮食限制对于预测25岁以上从事久坐工作的女性的BMI状况具有很高价值，而通过评估抑郁或焦虑严重程度无法预测BMI状况。
