Introduction: High periods of sedentary behavior characterize most police duties. In addition, the profession is highly stressful and exposes policemen to higher adverse health outcome risks, such as obesity and hypertension. Purpose: This study aimed to analyze the imapct of higher body mass index (BMI) on ambulatory BP and heart rate variability (HRV) and, to examine the correlation between obesity indicators, lipid profile, ambulatory BP and HRV in police officers. Methods: Operational police officers (n= 38) were categorized into BMI: lower (< 26.47 kg·m-2) and higher (> 26.47 kg·m-2)). Clinical and ambulatory (24h, awake and asleep) BP, and HRV indices were assessed. Results: Officers with higher BMI group exhibited higher clinical systolic (SBP) and diastolic BP (DBP) compared to those with lower BMI. Similarly, the higher BMI showed higher (p < 0.05) values of 24h (71 ±7 vs 66 ± 6 mmHg), awake (73 ± 7 vs 68 ± 6) and asleep (64 ± 9 vs 58 ± 8) DBP compared to the lower BMI group, without impairment ambulatory HRV indices. Moreover, this group also attained less distance in 12-min running test (2,305.26 ± 236.22 vs 2,486.47 ± 222.72; p = 0.02) and VO2max (40.25 ± 5.28 vs 44.36 ± 4.97 mL·kg-1·min-1; p = 0.02). Abdominal circumference correlated significantly with ambulatory BP (r = 0.35 to 0.49). Triglycerides (Rho/r = - 0.31 to - 0.33) and total cholesterol (Rho/r = - 0.37 to - 0.42) correlated significantly with ambulatory SDNN. Besides, triglycerides correlated significantly to awake and asleep (r/Rho = 0.34 and 0.38) DBP. Conclusion: Police officers with higher BMI showed higher ambulatory DBP, without evidence of cardiac autonomic modulation impairment. Obesity indicators correlated with ambulatory BP, while the lipid profile correlated with ambulatory DBP and HRV. [ABSTRACT FROM AUTHOR] |
