To examine coronary heart disease (CHD) risk factors, particularly blood lipids and smoking, in adolescent boys in the Sydney Metropolitan area, and to investigate possible differences between boys from English-speaking (ESB) and non-English-speaking backgrounds (NESBs).
Male volunteers aged 15-18 years were recruited from the senior years of four secondary schools in different geographical areas of Sydney.
Body mass index (BMI), waist-hip ratio (WHR), blood lipids, and percent body fat were measured.
Behavioral variables were estimated by questionnaire.
A total of 110 boys were recruited ; 74% were from an ESB.
Mean WHR (0.836 ± 0.045), waist circumference (80.6 ± 9.4 cm), and percent body fat (21.0 ± 6.3) were similar across age groups.
Atherogenicity of the lipid profile, as measured by the ratio of total cholesterol to high-density lipoprotein cholesterol (TC : HDL-C), was lower in boys aged 15 years than in any other age group (p<. 05).
TC : HDL-C was strongly associated with BMI (r=57 ; p<. 0001) and WHR (r=35 ; p<. 01).
Smokers had higher BMI, were less active and had lower HDL-C (p<. 001) and higher TC : HDL-C (p<. 0001) than non-smokers.
Smoking, even of short duration, and quite moderate consumption of cigarettes (6/day) were associated with a deterioration of the lipid profile.
Boys from NESBs had a higher degree of risk in all of the factors examined. (...)
