Hubungan Antara Indeks Massa Tubuh

Kejadian obesitas di kota besar saat ini semakin meningkat. Hubungan antara Indeks Massa Tubuh (IMT) dan penyakit kardiovaskular telah diketahui pada orang dewasa, tetapi pada remaja belum banyak diketahui. Penelitian ini bertujuan untuk menilai hubungan IMT dan peningkatan tekanan darah pada remaja obes di kota Bandung. Penelitian cross-sectional ini dilakukan pada bulan Juni-Agustus 2006. Subjek penelitian adalah anak sekolah menengah di kota Bandung berusia 15-18 tahun dengan indeks massa tubuh (IMT) > persentil ke-95 dan mengalami peningkatan tekanan darah > persentil ke-90 berdasarkan usia dan jenis kelamin. Derajat obesitas dinilai dengan mengukur indeks massa tubuh (IMT). Tekanan darah diukur dengan menggunakan spygmomanometer air raksa sesuai dengan cara baku National High Blood Pressure Education Program Working Gorup on High Blood Pressure in Children and Adolescents tahun 2004. Hubungan antara IMT dan peningkatan tekanan darah dianalisis dengan korelasi Pearson. Hasil pemeriksaan terhadap 3.170 remaja didapatkan 34 perempuan dan 43 laki-laki obes yang mengalami peningkatan tekanan darah. IMT pada remaja obes laki-laki berhu-bungan secara bermakna dengan tekanan darah sistol (r=0,628;p=0,000) maupun diastol (r=0,563;p=0,000). Sedangkan pada remaja obes perempuan IMT tidak mempunyai hubungan dengan tekanan darah sistol (r=0,087;p=0,624) maupun diastol (r=0,044;p=0,803). IMT berhubungan dengan peningkatan tekanan darah sistol dan diastol pada anak remaja obes laki-laki, tapi tidak ditemukan hubungan pada remaja perempuan.

The incidence of obesity in big cities has been increasing significantly. The correlation between obesity and risk of cardiovascular disease and hypertension in adults had been already known but studies in adolescent still lack. This study was performed to determine the association between degrees of obesity and increasing blood pressure in obese adolescents in Bandung. This study was performed to determine the association between degrees of obesity and increasing blood pressure in adolescents in Bandung. This cross-sectional study was conducted in June to August 2006. The subjects were students aged 15-18 years at high schools in Bandung with body mass index (BMI) was measured using CDC chart 2000 (>p95) and increasing blood pressure (>p90) depends on age and gender according to National High Blood Pressure Education Program Working Group on High Blood Pressure in Children and Adolescents 2004. Weight (kg) and length (m)2 measurement were used to measure degrees of obesity, followed by examination of blood pressure. Correlation between degrees of obesity and blood pressure was analyzed using Pearson correlation statistical test. Screening on 3,170 adolescents found obese 34 adolescent girls and 43 boys had increasing blood pressure. Correlation between BMI and systole blood pressure in boys was showed by r=0.628;p=0.000 and diastole was showed by r=0.563;p=0.000. Correlation between BMI and systole blood pressure in girls was showed by r=0.087;p=0.624 and diastole was showed by r=0.044;p=0.803. BMI was correlated with increasing blood pressure in adolescents boys in Bandung.
