Latar Belakang: Indeks massa tubuh (IMT) merupakan salah satu cara menentukan
ukuran tubuh ideal atau proporsional seseorang termasuk pada anak. Indeks massa
tubuh secara bermakna berkorelasi dengan jaringan lemak sub kutan maupun lemak
total dalam tubuh. Indeks massa tubuh seorang anak akan meningkat jika energi atau
kalori yang dikonsumsi sehari-hari berlebihan dan tidak diimbangi dengan aktivitas
fisik yang cukup. Dari beberapa penelitian yang ada menunjukkan bahwa
peningkatan indeks massa tubuh pada anak berkaitan erat dengan peningkatan
tekanan darah pada anak dan remaja yang bersangkutan.
Tujuan: Penelitian ini bertujuan untuk mengetahui apakah terdapat hubungan antara
indeks massa tubuh dengan tekanan darah anak usia sekolah dasar.
Metode:Penelitian ini bersifat analitik-observasional/non-eksperimental dengan
rancangan penelitian cross-sectional. Penelitian dilakukan pada anak-anak kelas 4
dan 5 SD Negeri Brengosan, Ngaglik-Sleman. Untuk mengetahui indeks massa
tubuh digunakan pengukuran antropometri sesuai usia dan jenis kelamin anak,
sedangkan tekanan darah diukur dengan tensimeter Riester. Analisis univariat berupa
tabel distribusi dan analisis bivariat menggunakan uji chi-square.
Hasil: Dari 50 subyek, seluruh subyek termasuk kriteria inklusi dan tidak ada yang
termasuk kriteria eksklusi sehingga semua subyek diikutsertakan dalam analisis.
Hasil analisis statistik menunjukkan nilai 95% Confidence Interval (95% CI) 1.61369.267 dengan Prevalence Ratio (PR) sebesar 10.571 dan nilai p-value (p<0.05)
sebesar 0.017, sehingga dapat disimpulkan bahwa terdapat hubungan antara indeks
massa tubuh dengan tekanan darah pada anak sekolah dasar.
Kesimpulan: Indeks massa tubuh mempengaruhi secara signifikan terhadap tekanan
darah anak usia Sekolah Dasar Brengosan kelas 4 dan 5
Kata kunci: Indeks massa tubuh, tekanan darah, anak usia sekolah dasar

ABSTRACT
Background: Body mass index (BMI) is one of the ways to measures propotional
body size in children. Body mass index correlates with the fat tissue and total body
fat. The body mass index in a child will increase if the energy or callories are over
consumed daily and there is no balance with the daily activities. Some research have
shown that the increase of body mass index in children correlates with the increase of
their blood pressure.
Objective: This study was aimed to determine whether there is a correlation between
body mass index and the blood pressure of the 4th and 5th grade Brengosan
elementary school students.
Methods: This is a cross-sectional, analytic observational/nonexperimental study.
The study was conducted to the 4th and 5th grade Brengosan Yogyakarta State
elementary school students.Their weights and heights were measured and their blood
pressures were also measured. The distribution tables were used in univariate analysis
while chi-square test was used in bivariate analysis.
Results: 50 subjects were included in the analysis and none of the students were in
the exclusion criterias. Statistical analysis showed the value of 95 % Confidence
Interval (95 % CI) was 1.613-69.267, the p-value (p < 0.05) was 0.017 and
Prevalence Ratio (PR) was 10.571, which means there was a correlation between
body mass index and the blood pressure of 4th and 5th grade Brengosan elementary
school students.
Conclusion: Body mass index correlates with the blood pressure of 4th and 5th grade
Brengosan elementary school students
Keywords: Body mass index, blood pressure, 4th and 5th grade elementary school
students
