초록

목 적 : 비만은 고혈압의 위험 인자로서 소아 청소년기의 비만이 성인기의 비만으로 발전하기 때문에 결국 소아 청소년기의 비만으로 심혈관계 등 여러 문제가 유발된다고 볼 수 있다. 따라서 소아 청소년기 비만증에서 정확한 혈압의 측정은 매우 중요하겠다. 본 연구에서는 소아 청소년 비만 환자들을 대상으로 수시 혈압 측정으로 선별 검사한 후 이들의 24시간 혈압을 측정함으로 ABPM의 유용성과 의미에 대해 고찰해보고자 하였다. 방 법 : 2006년 2월 1일부터 2007년 12월 1일까지 한동대학교 선린병원의 소아 청소년과를 방문하여 ABPM을 시행한 모든 환자들을 대상으로 하였다. 자료의 분석은 수축기, 이완기 혈압측정을 수면 혈압과 이를 제외한 각성 혈압으로 나누어 분석하였고 야간 혈압 강하(night dip)를 평가하였다. 환자는 정상군(1군)과 체질량계수만 95 백분위수가 넘는 비만군(2군) 그리고 비만이면서 외래혈압이 120/80 mmHg이상인 비만 위험혈압군(3군)으로 구분하였다. 결 과 : ABPM을 시행한 환자는 모두 49명이었고 비만군이 18명이었고 비만 위험혈압군이 12명이었다. 정상군은 19명이었다. 각 군의 수축기 평균혈압을 비교하였을 때 모든 군에서 통계학적으로 의미 있는 차이를 나타내었고(1군, $105.1{\pm}4.7$; 2군, $111.0{\pm}7.1$; 3군, $117.8{\pm}6.6mmHg$), 이완기 평균 혈압의 경우 1군과 3군에서만 통계학적으로 의미 있는 차이를 나타내었다($69.1{\pm}5.3$, $77.9{\pm}6.3mmHg$). 각성 혈압을 비교한 결과도 1군과 3군간에만 통계적으로 유의한 차이가 있었다. 수면혈압인 경우 수축기 혈압은 3군이 1, 2군에 비해 통계적으로 유의하게 높았으나, 이완기 혈압은 다른 경우와 마찬가지로 1군과 3군간에만 유의한 차이가 있었다. 본 연구에서 각 군간에 야간 혈압 강하를 조사해보니 통계적으로 의미 있는 차이를 보이지 않았다. 결 론 : 본 연구에서 ABPM을 시행한 결과 비만 위험혈압군에서 통계적으로 유의하게 혈압이 높았다. 소아 청소년에서, 특히 향후 심혈관 질환 및 여러 질환의 위험인자로 알려진 비만아에서 ABPM의 적극적인 활용이 필요로 하겠다.

Purpose : Obesity in children and adolescence is highly correlated with adult obesity, which can provoke hypertension. Therefore, it is important to evaluate the blood pressure of obese children regularly. In this study, the results of ambulatory blood pressure monitoring (ABPM) in obese children and adolescents were evaluated. Methods : ABPM was conducted for selected patients who visited Handong University Sunlin Hospital from Feb. 1, 2006 to Dec. 1, 2007. The patients were classified into 3 groups: group 1 was normal, group 2 had normal casual blood pressure and a body mass index over the 95th percentile, and group 3 had high casual blood pressure over 120/80 mm Hg and a body mass index over the 95th percentile. Systolic and diastolic 24-hour blood pressure was measured, including both day and night. Results : There were 49 patients in the study. The results showed a significant difference for average systolic blood pressure between the three groups ($105.1{\pm}4.7$, $111.0{\pm}7.1$, $117.8{\pm}6.6mmHg$, P<0.001), but for average diastolic blood pressure only between groups 1 and 3 ($69.1{\pm}5.3$, $77.9{\pm}6.3mmHg$, P=0.001). In the daytime, only groups 1 and 3 showed a statistically significant difference for systolic and diastolic blood pressure. During the night the systolic pressure of group 3 was significantly higher than the other groups, but the diastolic pressure of group 3 was only higher than that group 1. No statistical difference was found in night dips among the groups. Conclusion : Ambulatory blood pressure monitoring in children and adolescents showed statistically higher blood pressure in obese patients with high casual blood pressure.
