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.
在高血压患者中，作为日间血压变化的一部分，缺乏生理性血压下降被称为非杓型血压。在此，我们研究了高血压特征与身体成分指数之间的关系。本研究共纳入 104 例患者（54 例男性，平均年龄：47.6±12.1 岁）。测量患者的身高、体重、腰围和臀围，并计算身体成分指数。记录所有患者的诊室血压测量值和 24 小时动态血压读数。与日间血压读数相比，血压下降至少 10%称为杓型血压，而下降小于 10%则称为非杓型血压。根据动态血压读数，将患者分为第 1 组（杓型模式；51 例，34 例男性，平均年龄 45.6±12.3）和第 2 组（非杓型模式，53 例；20 例男性，平均年龄 49.6±11.6）。第 1 组中女性和吸烟者的比例明显低于第 2 组。第 2 组的 BRI、BAI、腰高比和腰围均明显高于第 1 组。身体圆润指数（BRI）、身体脂肪指数（BAI）、腰重比和 WC 与夜间平均收缩压和舒张压读数呈显著正相关。收缩压夜间下降百分比与腰高比、BAI 和 BRI 显著相关。同样，舒张压夜间下降百分比与腰高比、BAI 和 BRI 相关。总之，相对较新的身体成分指数，即 BRI 和 BAI，与非杓型患者的夜间血压读数关系更密切。
