Cardiorespiratory fitness and body mass index of 9–11-year-old English children: a serial cross-sectional study from 1998 to 2004

Abstract

Objective:

To examine the changes over time in cardiorespiratory fitness and body mass index (BMI) of children.

Design:

Serial cross-sectional, population-based study.

Setting:

Primary schools in Liverpool, UK.

Participants:

A total of 15 621 children (50% boys), representing 74% of eligible 9–11-year olds in the annual school cohorts between 1998/9 and 2003/4, who took part in a 20m multi-stage shuttle run test (20mMST).

Main outcome measures:

Weight, height, BMI (kg/m2) and obesity using the International Obesity Taskforce definition.

Results:

Median (95% confidence interval) 20mMST score (number of runs) fell in boys from 48.9 (47.9–49.9) in 1998/9 to 38.1 (36.8–39.4) in 2003/4, and in girls from 35.8 (35.0–36.6) to 28.1 (27.2–29.1) over the same period. Fitness scores fell across all strata of BMI (P<0.001). Moreover, BMI increased over the same 6-year period even among children in fittest third of 20mMST.

Conclusion:

In a series of uniform cross-sectional assessments of school-aged children, BMI increased whereas cardiorespiratory fitness levels decreased within a 6-year period. Even among lean children, fitness scores decreased. Public health measures to reduce obesity, such as increasing physical activity, may help raise fitness levels among all children – not just the overweight or obese.
