The first step of all healthcare actions aimed at promoting an appropriate quality of life for infants affected by Down syndrome (DS) is to ensure their survival. This investigation was aimed at estimating the infant mortality rate of infants affected with DS in urban populations of South America. Thirty-three hospitals included in the Latin American Collaborative Study of Congenital Malformations (ECLAMC) distributed in 23 cities of 5 South American countries followed 360 liveborn DS cases born during the 1988-1992 period. Families were recontacted after the infant should have reached the age of one year. The collected data included information about health status; i.e., frequency and dates of diagnosed illnesses and hospital admissions, and, in case of death, information on date, place and cause of death, and illness immediately before death. Information about the interviews included place, date, and name of the interviewer. A closed questionnaire was employed by the interviewers, mostly physicians, nurses, and social workers. Life table analysis up to the age of one year was performed by the actuarial survival method. The overall mean survival at age one year was 0.736 (SE=0.023). Thirty-three (9.2%) of the 360 cases died neonatally, and 62 (17.2%) within the remaining 2-to-12-month interval. The probability of survival at one year of age did not differ between public (209 cases; mean 0.718; SE=0.031) and private (151 cases; mean: 0.762; SE=0.035) (chi2:0.87; df:1; P >0.05) health systems. The 150 DS cases with a congenital heart defect (CHD) had a significantly lower P robability of survival at the age of one year (mean: 0.660; SE: 0.039) than did the 210 cases without CHD (mean: 0.790; SE: 0.028) (chi2:6.67; df:1; P <0.01). The death rate in the first year of life for DS cases without a detected cardiac defect (21%) is significantly higher than that reported in developed countries; namely, 16% from Italy, 11% from Canada, 10% from England, and 7% from Denmark. |
