Long-term trends in childhood diabetes mortality: 1968-1998.

OBJECTIVE In the context of recent improvements in type 1 diabetes therapy, to describe longitudinal trends in mortality attributable to childhood diabetes and to investigate socioeconomic and health services correlates of mortality. RESEARCH DESIGN AND METHODS We extracted mortality data for 1968-1998 from National Center for Health Statistics files and covariates from the Bureau of Health Professions Area Resource File. Analytical techniques included linear and Poisson regression and standard descriptive statistics. RESULTS Childhood (defined as 0-19 years of age) age-adjusted mortality from diabetes declined from 9.5 (1968) to 3.0 (1984) deaths per 10 million but remained relatively constant subsequently. All-cause childhood mortality, however, continued to decline. Older children experienced higher mortality rates, as did those living in counties with higher levels of unemployment. CONCLUSIONS Despite recent improvements in therapy, diabetes-related mortality among children has not declined for 14 years. This finding may be partially attributable to sociodemographic factors influencing access to care, but the remaining mortality may defy available treatment methods. Reducing childhood diabetes mortality rates below the current apparent plateau may require new prevention and/or treatment strategies.
