Aim: Limited cardiovascular disease (CVD) risk data are availablefor firefighters worldwide. This comparative study was aimedat investigating the biochemical and nutritional indices offirefighters in Iran.

Materials and methods: Individuals’ anthropometric measurements, including weight,height, and waist and hip circumferences, were measured andthe percent of body fat (BF%) was also obtained. Blood samplingwas done in order to determine lipid profile, including totalcholesterol (TC), triglycerides (TG), low-density lipoproteincholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C),lipoprotein a (Lp(a)) and fasting blood sugar (FBS) concentrations.Systolic and diastolic blood pressures (SBP and DBP) were alsomeasured.

Results: The mean ages of firefighters and administrative staff were 42.45 ± 6.75 and 44.64 ± 5.83 y, respectively. The prevalence of overweight and obesity was 45% and 24% in firefighters and 54% and 23% in administrative staff, respectively. High waist-to-hip and waist-to-stature ratios were detected in 26.4% and 81.3% of firefighters versus 33.3% and 89.7% of the control group, respectively. No significant differences were observed between the mean of TC, TG, HDL-C, LDL-C and FBS concentrations. The mean of Lp(a) was significantly higher among firefighters (P<0.05). About half of the subjects in bothgroups had TC >5.17, TG >1.69, HDL-C <1.03 nmol/L andLp(a) >25 mg/dL. There were no significant differences betweenthe SBP and DBP of subjects. There was no significant differencein smoking habits between the two groups.

Conclusions: Considering the high prevalence of overweight and obesity, highTC, TG and Lp(a) and low HDL-C concentrations among all firefighters,it seems necessary to provide fitness-promotion and nutritionaleducation programs for the prevention of obesity-related chronicdiseases such as CVD.
