    Summary

    Tuberculosis incidence in US children (0-14 years) unexpectedly stabilized from 1976-1981, halting a prior decline. This trend was influenced by Hispanic and Indochinese refugee children.

    Area of Science:

    • Pediatric Infectious Diseases
    • Public Health Surveillance
    • Epidemiology

    Background:

    • Tuberculosis (TB) incidence in US children (0-14 years) had shown a consistent annual decline of approximately 9% from 1962 to 1975.
    • This downward trend unexpectedly ceased between 1976 and 1981.

    Purpose of the Study:

    • To analyze the tuberculosis case rate trends in children aged 0-14 years in the United States from 1976 to 1981.
    • To identify demographic factors contributing to the observed stability in TB incidence.

    Main Methods:

    • Analysis of national tuberculosis surveillance data for children aged 0-14 years.
    • Examination of trends by sex, race, and specific ethnic groups.

    Main Results:

    • The overall incidence of tuberculosis among children aged 0-14 years in the US failed to decline between 1976 and 1981.
    • This stability was observed across both sexes and racial groups.
    • Data from 1980-1981 indicated that Hispanic children may have been a key factor in the stability among white children.
    • Tuberculosis cases among Indochinese refugee children appeared to account for the stability in the case rate among children of other races.

    Conclusions:

    • The stabilization of tuberculosis incidence in US children during 1976-1981 marked a significant deviation from previous trends.
    • Specific pediatric populations, including Hispanic and Indochinese refugee children, played a crucial role in this epidemiological shift.
