Unexpected Infant Death

AbstractThe effect of altitude on the risk of sudden infant death syndrome (SIDS) has been reported previously, but with conflicting findings. We aimed to examine whether the risk of sudden unexpected infant death (SUID) varies with altitude in the United States. Data from the Centers for Disease Control and Prevention (CDC)’s Cohort Linked Birth/Infant Death Data Set for births between 2005 and 2010 were examined. County of birth was used to estimate altitude. Logistic regression and Generalized Additive Model (GAM) were used, adjusting for year, mother’s race, Hispanic origin, marital status, age, education and smoking, father’s age and race, number of prenatal visits, plurality, live birth order, and infant’s sex, birthweight and gestation. There were 25,305,778 live births over the 6-year study period. The total number of deaths from SUID in this period were 23,673 (rate = 0.94/1000 live births). In the logistic regression model there was a small, but statistically significant, increased risk of SUID associated with birth at > 8000 feet compared with < 6000 feet (aOR = 1.93; 95% CI 1.00–3.71). The GAM showed a similar increased risk over 8000 feet, but this was not statistically significant. Only 9245 (0.037%) of mothers gave birth at > 8000 feet during the study period and 10 deaths (0.042%) were attributed to SUID. The number of SUID deaths at this altitude in the United States is very small (10 deaths in 6 years).

Power Needs

To the Editor.— There have been several attempts to define the person-power needs for neonatologists in the United States.1-3 The reports by Merenstein et al2 and the AAP Committee on Fetus and Newborn1 maintain that there is presently an adequate number of neonatologists, whereas in a 1981 editorial, Robertson3 predicted increasing shortages of neonatologists. Why the difference between the conclusions? My answer to this question is that the reports by Merenstein et al and the AAP used calculated ratios of neonatologists to live births or lengths of stay, whereas the Robertson editorial expressed concern about the critical care needs of the physiologically unstable neonate.

To the Editor.— It was encouraging to see the results of the recent study from France on the prevention of preterm births published in Pediatrics.1 Pediatricians have long supported preventive measures to improve infant and child health. But, pediatricians, in general, and neonatologists, in particular, have been slow to assume an advocacy position for an obvious, important preventive effort, namely, reducing the incidence of low birth weight. During the last 20 years, the United States has experienced a dramatic improvement in neonatal mortality, from rates of neonatal death of 18 per 1,000 live births in 1965 to 6.8 per 1,000 live births today.2,3

Abstract Mortality from Hodgkin’s disease in the United States during the period 1921 through 1951 was analyzed with respect to race, sex and age incidence and distribution. The findings were compared with those reported for leukemia. The recorded death rate from Hodgkin’s disease rose from 6.9 in 1921 to 17.0 per million in 1951. During this period, the death rate from leukemia rose from 14 to 61 per million. The death rate among males is higher than among females for both diseases; the male predominance is more marked in Hodgkin’s disease than in leukemia. The rate is higher among whites than non-whites for both diseases; the white predominance is more marked in leukemia than in Hodgkin’s disease. There is no peak in rate during childhood for Hodgkin’s disease as there is for leukemia, and the increase in rate with age is much less steep for Hodgkin’s disease than for leukemia. The mean age at death of adults dying from Hodgkin’s disease and from leukemia increased by 3.5 and 8.0 years, respectively, between 1925 and 1950. The male-female sex ratio for Hodgkin’s disease decreased slightly, and increased slightly for leukemia between 1925 and 1950.
