Among hypertensive subjects, the lack of physiological blood pressure drop as part of diurnal blood pressure variations is termed as non-dipper blood pressure. Herein, we investigated the relationship between hypertension character and body composition indices. This study included a total of 104 patients (54 M, mean age: 47.6 +/- 12.1 years). Patients' heights, weights, and waist and hip circumferences were measured, and body composition indices were calculated. All patients' office blood pressure measurements and 24-hour ambulatory blood pressure readings were recorded. A blood pressure drop of at least 10% compared with daytime blood pressure readings is called dipper blood pressure, while a drop of less than 10% is termed as non-dipper blood pressure. Based on ambulatory blood pressure readings, the patients were grouped into Group 1 (dipper pattern; 51 pts, 34 M, mean age 45.6 +/- 12.3) and Group 2 (non-dipper pattern, 53 pts; 20 M, mean age 49.6 +/- 11.6). The proportion of females and smokers were significantly lower in Group 1 than Group 2. BRI, BAI, waist-to-height ratio, and waist circumference were significantly higher in Group 2 than Group 1. There were significant positive correlations between body roundness index (BRI), body adiposity index (BAI), waist-to-weight ratio, and WC and nocturnal mean systolic and diastolic blood pressure readings. Percent systolic nocturnal drop was significantly correlated with waist-to-height ratio, BAI, and BRI. Similarly, percent diastolic nocturnal drop and waist-to-height ratio, BAI, and BRI were correlated. In conclusion, the relatively new body composition indices, namely BRI and BAI, are more closely related to nocturnal blood pressure readings among non-dipper subjects.
