目的探讨母亲职业因素与低出生体质量儿发生率的关系。②方法对青岛市市区１９９４年１～１２月出生的５７７４例新生儿及其母亲的情况，进行单因素和多因素的Ｌｏｇｉｓｔｉｃ回归分析。③结果母亲职业因素与低出生体质量儿的发生率有关，教师职业有较高的低出生体质量儿发生率，相对于干部职业，其调整相对危险度（ＲＲｓ）为３．６５（９５％ＣＩ＝１．９１，６．９７），其次为服务员职业，ＲＲｓ为１．９９（９５％ＣＩ＝１．２２，３．２３），第３为其他职业，ＲＲｓ为１．６３（９５％ＣＩ＝１．１９，２．２４）。④结论母亲职业与低出生体质量儿的发生率有关。 Objective To explore the relationship between maternal occupational factors and the incidence of low birth weight children. Methods The 5774 newborns and their mothers born from January to December 1994 in downtown of Qingdao were analyzed by single factor and multiple logistic regression analysis. Results The occupational factors of mothers were related to the incidence of low birth weight children. Teachers’ occupations had a higher incidence of low birth weight children. The adjusted relative risk (RRs) was 3.65 (95% CI = 1.91,6.97), followed by attendant occupations, with RRs of 1.99 (95% CI = 1.22, 3.23), and for other occupations, RRs of 1.63 (95% CI = 1.19, 2.24). ④ Conclusion Maternal occupation and the incidence of low birth weight children.
