Chapter X. Congenital Anomalies 215 CONGENITAL ANOMALIES OF OTHER SYSTEMS Anomalies of the respiratory system were found in 71 deceased infants in 15 l)rojects combined (Table 103). In 14 of these (lentils the anomalies were unrelated to the process of death. In tile California project, in 23 out of tie 26 infant deaths due to these conditions they acted as underlying or assoeiated causes, Illost of the deatis (20) being due to Ipulmonary hypoplasia Icategory 748.6). All eight anomalies of the resp)iratory system in the Sherbrooke Iprojeet acted as associated causes, and four of them were contrii)utorv to allsence of diaphragnl (756.8k as unlierlying ealus,. Another was associated with aneneeplhalus as underlying cause and also with absence of diaphragm as associated cause. In one death plilllonary hypoi)lasia was associated witil cystic fibrosis T273.0 1. Another of these anolmalies was associated witil renal agenesis an(l tile last of the eight was associated with (oaretation of aorta 1747.11 as underlying cause. Clubfoot (754) was found in 178 deceased infants and was unrelated to the process of death in 175. In the remaining three infants, a complication of trealtment triggered the chain of events leading to death. Tile highest rates for this anomnaly were found in San .huan Province and in tile Chilean project, where there were 72.8 and 62.0 leceased infants with clubfoot per 100,000 live birth,, respectively. Among the 370 infant (leatils in which ol0r anomalies of the museuloskeletal system such (755, conditions 756) were involved found, as in underlying only 109 were or associated causes. In 52 of these 109 (lentils they were underlying causes; 50 belonged to category 756 and the other two were assigned to (atgoy 755. The other 57 deesed infnts had 44 omlieos belonging to category 756 as assoeinted causes and only 13 assigned to category 755, also as associated ealses. Therefore. it seems oxidIlt that conditions in entegory 7,56 are more sorioue from tle standpoint of mortality than those in categories 754 and 755. MORTALITY BY AGE OF MOTHER Tile influence of maternal age on anomalies in the products of gestation is usually an important factor. In this presentation tile death rates by maternal age have been shown for Down's disease and for anolialies of tile nervous and tile circulatory systems. Augmented rates were noted with increased Imaternal age ill )own's disease, whicih ilrobably raised the rates for anomalies of the circulatory system owing to tile frequent association of these two conditions (10.3 per cent of the deceased infants with cirdulatory anomalies had Down's disease as well). In Table 125 the distribution of deceased infants with congenital anonlalies is given by age of mother at tile infant's birth. Of tile total, 32.8 per cent were born to mothers aged 30 years and over (excluding those with age unknown). This nereentae is
