Birthweight is known to be affected by several factors. In the present study a relationship model of psychological and economic determinants of birthweight was designed and tested.
This prospective study involved 400 pregnant women in four districts of Tehran, Iran. The subjects were selected through a multistage sampling method. Seven questionnaires (socioeconomic status; Holmes and Rahe Stress Scale; Perceived Stress Scale; 21-item Depression, Anxiety, and Stress Scale [DASS-21]; perceived social support; pregnancy-related anxiety scale; and domestic violence questionnaire) were used to assess participant psychosocial and economic conditions. In order to collect post-partum information about the mother and the infant, the women were followed up until delivery. Data were analyzed using SPSS-16 and Lisrel-8.8.
Based on the obtained path diagram, the greatest adverse effects on birthweight were exerted directly by DASS-21 score (B = -0.14) and indirectly by stressful life events (B = -0.037). Among variables that affected birthweight in both paths, socioeconomic status and perceived stress had the strongest overall effects on birthweight (B = 0.203 and -0.1024, respectively).
According to the path analysis model, psychosocial and economic factors can directly/indirectly affect birthweight.
已知出生体重受多种因素影响。在本研究中，设计并测试了一个关于出生体重的心理和经济决定因素的关系模型。
这项前瞻性研究涉及伊朗德黑兰四个区的400名孕妇。通过多阶段抽样方法选取研究对象。使用七份问卷（社会经济地位；霍姆斯和拉赫压力量表；感知压力量表；21项抑郁、焦虑和压力量表 [DASS - 21]；感知社会支持；与妊娠相关的焦虑量表；以及家庭暴力问卷）来评估参与者的心理社会和经济状况。为了收集产后关于母亲和婴儿的信息，对这些女性进行随访直至分娩。使用SPSS - 16和Lisrel - 8.8对数据进行分析。
根据所得路径图，对出生体重产生最大不利影响的直接因素是DASS - 21得分（B = -0.14），间接因素是应激性生活事件（B = -0.037）。在两条路径中影响出生体重的变量中，社会经济地位和感知压力对出生体重的总体影响最强（分别为B = 0.203和 -0.1024）。
根据路径分析模型，心理社会和经济因素可直接/间接影响出生体重。
