Daily step counts and selected coronary heart disease risk factors in adolescent girls

Summary Data on objectively determined physical activity (PA) behaviour of Australian adolescent girls is lacking along with known associations between PA behaviour and future risk of coronary heart disease (CHD). The purpose of this study was to measure four consecutive days of pedometer steps and...

Zusammenfassung:	Summary Data on objectively determined physical activity (PA) behaviour of Australian adolescent girls is lacking along with known associations between PA behaviour and future risk of coronary heart disease (CHD). The purpose of this study was to measure four consecutive days of pedometer steps and the prevalence of selected CHD risk factors in a cross-sectional sample of 415 Australian adolescent girls (age 16 ± 0.8 year; mean ± S.D.). Coronary heart disease risk factors assessed were low levels of daily PA (95th percentile), overweight (>85th percentile) and/or obese (>95th percentile), presence of family history of heart disease, low cardio-respiratory fitness (poor estimated VO2 max), and being a smoker. Overall, 41.2% of the sample had ≥2 factors. The mean number of steps per day was 9617 ± 3108 (mean ± S.D.). There was a significant relationship between daily ambulatory activity of
