This study focused on the possible role of psychosocial factors on intrauterine fetal growth. Pregnant women (n = 236) completed questionnaires on daily stressors and psychosomatic symptoms three times during pregnancy; in the 11-12th week, the 23-24th week and the 35-36th week. In addition, information was obtained on the quality of the marital relationship, social support, social class, physical work load, weight of the biological parents and life-style variables (including smoking, alcohol and coffee consumption). Birth weight corrected for gestational age, sex and parity was utilized as an index of intrauterine fetal growth. This dependent measure did not appear to be affected by exposure to daily stressors or disturbed maternal well-being on any of the measuring points. Smoking appeared to be the best predictor of fetal growth, together with maternal weight and the family's socioeconomic status. These variables accounted for 10.6% of the variance. It is postulated that the absence of a relationship between stressors and fetal development may be due to the buffering effects of adequate emotional support provided by the partners and the further social network.
本研究聚焦于心理社会因素对子宫内胎儿生长可能产生的作用。236名孕妇在孕期三个阶段（第11 - 12周、第23 - 24周和第35 - 36周）完成了关于日常压力源和身心症状的问卷调查。此外，还获取了婚姻关系质量、社会支持、社会阶层、体力工作负荷、亲生父母体重以及生活方式变量（包括吸烟、饮酒和咖啡摄入量）等信息。校正了胎龄、性别和胎次后的出生体重被用作子宫内胎儿生长的指标。在任何测量点，该因变量似乎都未受到日常压力源暴露或母亲幸福感紊乱的影响。吸烟似乎是胎儿生长的最佳预测因素，同时还有母亲体重和家庭社会经济地位。这些变量解释了10.6%的方差。据推测，压力源与胎儿发育之间不存在关联可能是由于伴侣及更广泛社交网络提供的充分情感支持起到了缓冲作用。
