Tujuan : Mengetahui hubungan kadar magnesium serum dan asupan magnesium dengan hipertensi, serta hubungan magnesium serum, asupan magnesium dan tekanan darah dengan faktor-faktor yang mempengaruhinya, pada orang dewasa > 35 tahun. Tempat: Kecamatan Mampang Prapatan, Jakarta Selatan Bahan dan cara : Studi cross sectional dilakukan pada 105 subyek pria dan wanita > 35 tahun yang dipilah secara simple random sampling dari sampel MONICA Jakarta 2000. Data yang dikumpulkan meliputi: data umum subyek, asupan makanan, antropometri, tekanan darah, pemeriksaan laboratorium (kadar magnesium serum, kreatinin serum dan gula darah puasa). Data dianalisis dengan uji statistik Chi-square, Fisher's exact, Kolmogorov-Smirnov, Anova dan t- tes. Hasil : Hipertensi didapatkan pada 40 % subyek dan makin banyak pada kelompok umur yang lebih tua. Sebanyak 38,8% subyek pria dan 55,4% subyek wanita mempunyai asupan magnesium kurang, Hipomagnesemia lebih sering terjadi pada subyek hipertensi daripada subyek tidak hipertensi. Dari hasil analisis bivariat, didapatkan hubungan bermakna antara :1) perilaku gizi dengan pola makan, 2) umur dan pola makan dengan asupan magnesium, 3) umur dengan tekanan sistolik, 4) asupan protein dengan tekanan darah sistolik, 5) asupan magnesium dengan tekanan darah diastolik dan hipertensi. Rata-rata kadar Mg serum lebih rendah pada subyek hipertensi, namun tidak terdapat hubungan bermakna antara kadar Mg serum dengan hipertensi. Simpulan : Defisit asupan magnesium didapatkan pada semua subyek dan terutama berhubungan dengan pola makan yang kurang baik. Kurangnya asupan magnesium makanan dan rendahnya magnesium serum dapat menjadi salah satu faktor penunjang hipertensi.
The Relationship Between Serum And Dietary Magnesium With Hypertension And The Influential Factors In Adults In Mampang Prapatan District, JakartaObjective: to determine the relationship between serum and dietary magnesium with hypertension, and the relationship between serum magnesium, dietary magnesium and blood pressure with the influential factors in age > 35 year. Location: Mampang Prapatan District, South Jakarta. Materials and method: A cross-sectional study had been carried out among 105 subjects selected by simple random sampling method. The collected information consist of socioeconomic status, smoking and physical activities, dietary intake, anthropometric, blood pressure and laboratory examinations for serum magnesium, creatinine serum and fasting blood glucose. Statistical analysis was performed by Chi Square, Fisher's exact, Kolmogorov-Smirnov, Anova and t -test. Results: Hypertension was found in 40 % subjects and more prevalent in older groups. Low level of magnesium intake was found in 38,8 % men and 55,4% women. Hypomagnesaemia was more prevalent in hypertensive subjects than in non-hypertensive. Bivariat analysis found significant relationships between :1) nutritional behavior with food pattern, 2) age and food pattern with dietary magnesium intake,3) age with systolic blood pressure, 4) dietary protein intake with systolic blood pressure, 4) dietary magnesium intake with diastolic blood pressure and hypertension. The average serum magnesium level was lower in hypertensive subjects, but no significant relationship between serum Mg levels with hypertension. Conclusions: Dietary magnesium deficit was found in all of subjects, especially associated with the poor food pattern. The reduced level in magnesium diets and the low level of magnesium serum could be a responsible factor in the development of hypertension. |
