Body mass index, waist circumference and chronic disease risk factors in Australian adolescents

Journal Article


Abstract


  • Objective: To determine the association between measures

    of adiposity (body mass index and waist circumference)

    and risk factors for heart disease, type 2 diabetes,

    fatty liver disease, and the clustering of risk factors

    in middle adolescence.

    Design: Cross-sectional study.

    Setting: Secondary schools in Sydney.

    Participants: Grade 10 students (N=496; 58.4% boys;

    mean [SD] age, 15.4 [0.4] years).

    Main Exposures: Height, weight, waist circumference,

    blood pressure, and fasting blood samples.

    Outcome Measures: Participants were categorized as

    overweight or obese using the International Obesity Task

    Force cut points and the UK waist circumference cut

    points. Blood was analyzed for high- and low-density lipoprotein

    cholesterol, triglycerides, insulin, glucose, alanine

    aminotransferase, -glutamyltransferase, and highsensitivity

    C-reactive protein levels, and the results were

    categorized as normal or abnormal according to published

    guidelines where possible. Associations between

    overweight and obesity and risk factors were explored

    using logistic regression. Clustering of risk factors within

    individuals was also explored.

    Results: Insulin (P.001), alanine aminotransferase

    (P.001), -glutamyltransferase (P = .005), highdensity

    lipoprotein cholesterol (P.001), highsensitivity

    C-reactive protein (P.001), and blood pressure

    (P.001) were significantly associated with

    overweight and obesity in adolescent boys. In adolescent

    girls, insulin, high-density lipoprotein cholesterol

    (P.001), and high-sensitivity C-reactive protein

    (P.001) were significantly associated with overweight

    and obesity. Obese adolescent boys and girls were significantly

    more likely to have 2 or more risk factors (boys:

    73.5% vs 7.6%; girls: 44.4% vs 5.4%; P.001 for both)

    than nonoverweight adolescents.

    Conclusions: Overweight and obese adolescents, especially

    boys, are at substantial risk for chronic conditions.

    Waist circumference is not a better predictor of

    metabolic risk factors than is body mass index.
