Disparities in Peaks, Plateaus, and Declines in Prevalence of High BMI Among Adolescents.
Summary of "Disparities in Peaks, Plateaus, and Declines in Prevalence of High BMI Among Adolescents."
Objectives: The objective of this study was to investigate trends in prevalence of high BMI from 2001 to 2008 and examine racial/ethnic disparities. Methods: Records for a total of 8 283 718 fifth-, seventh-, and ninth-grade students who underwent California's school-based BMI screening between 2001 and 2008 were included. Logistic regression identified trends in prevalence of high BMI (>/=85th, >/=95th, >/=97th, and >/=99th percentiles). Results: For 3 of 4 BMI cut points, prevalence continued to increase for black and American Indian girls through 2008, Hispanic girls plateaued after 2005, non-Hispanic white girls declined to 2001 prevalence levels after peaking in 2005, and Asian girls showed no increases. Non-Hispanic white boys peaked in 2005, then declined to 2001 prevalence levels for all BMI cut points; Hispanic and Asian boys declined after 2005 (for 3 lowest BMI cut points only) but remained above 2001 levels; and American Indian boys peaked later (2007) and declined only for BMI >/=95th. No girls and few boys showed a decline after peaking in prevalence of BMI >/=99th percentile. In 2008, disparities in prevalence were greatest for BMI >/=99th percentile, with prevalence of 4.9% for American Indian girls and 4.6% for black girls versus 1.3% for non-Hispanic white girls. Conclusions: On the basis of statewide California data, prevalence of high BMI is declining for some groups but has not declined for American Indian and black girls. These trends portend greater disparities over time, particularly in severe obesity. Interventions and policies that are tailored to the highest risk groups should be pursued.

Medical and Biotech [MESH] Definitions
The constant presence of diseases or infectious agents within a given geographic area or population group. It may also refer to the usual prevalence of a given disease with such area or group. It includes holoendemic and hyperendemic diseases. A holoendemic disease is one for which a high prevalent level of infection begins early in life and affects most of the child population, leading to a state of equilibrium such that the adult population shows evidence of the disease much less commonly than do children (malaria in many communities is a holoendemic disease). A hyperendemic disease is one that is constantly present at a high incidence and/or prevalence rate and affects all groups equally. (Last, A Dictionary of Epidemiology, 3d ed, p53, 78, 80)
A rheumatic syndrome of possibly allergic origin, usually affecting children and adolescents, and characterized by high fever, exanthema, arthralgia, leukocytosis, and increased sedimentation rate.
Differences in access to or availability of facilities and services
Health Status Disparities
Variation in rates of disease occurrence and disabilities between socioeconomic and /or geographically defined population groups.
Precursor B-cell Lymphoblastic Leukemia-lymphoma
A leukemia/lymphoma found predominately in children and adolescents and characterized by a high number of lymphoblasts and solid tumor lesions. Frequent sites involve LYMPH NODES, skin, and bones. It most commonly presents as leukemia.
