Abstract: We sought to study the association between some common birth defects and parental occupations. The live births and congenital malformation born between January 1994 and December 1998 were obtained from the Singapore National Registry of Births and Deaths (the National Birth Defect Registry). The prevalence of overall birth defects among Singapore live births during the study period is 13.9 per 1000 live births. The most frequent single coding defects were "bulbus cordis anomalies and anomalies of cardiac septal closure (BCA)," "congenital anomalies of urinary system (CUS)," "cleft palate and cleft lip (CPL)," and "certain congenital musculoskeletal deformities (CMD)." Using the "Legislators, Senior Officers & Managers" as reference and adjusting for possible confounders, there were significant associations for: (1) paternal "clerical workers" (adjusted RR 2.25) with the BCA; (2) maternal "professionals" with CUS (adjusted risk ratio [RR] 3.58); (3) paternal "production craftsmen and related workers" with both the BCA (adjusted RR 2.04), and the CMD (adjusted RR 2.83); (4) paternal "plant and machine operators and assemblers" with the BCA (adjusted RR 2.49), and the CUS (adjusted RR 5.19), and the CMD (adjusted RR 3.01). Paternal rather than maternal exposure might be more important in the causation of some common birth defects in Singapore.
