ABSTRAK Penelitian dengan rancangan uji klinis paralel acak tersamar ganda ini bertujuanmengetahui perubahan kadar apo B pada penyandang obes I setelah suplementasiserat psyllium husk (PH) 8,4 g/hari dan diet rendah kalori seimbang (DRKS) 1200kkal/hari selama 4 minggu. Berdasarkan kriteria penelitian, didapat 31 orangsubyek yang dibagi menjadi dua kelompok, 15 orang kelompok perlakuan (KP)dan 16 orang kelompok kontrol (KK). Subyek KP mendapat PH 8.4 g/hari danDRKS, sedangkan KK mendapat plasebo dan DRKS. Data yang diperolehmeliputi sebaran dan karakteristik subyek, asupan energi, makronutrien, serat, danair, serta kadar apo B awal dan akhir penelitian. Analisis data menggunakan uji ttak berpasangan dan Mann-Whitney, batas kemaknaan 5%. Sejumlah 28 subyekdapat mengikuti penelitian hingga selesai (KP dan KK masing-masing 14). Tidakdilaporkan efek samping berbahaya selama perlakuan. Sebagian besar subyekperempuan, median usia subyek KP dan KK berturut-turut 35,0 (30−45) tahun dan34,50 (30−48) tahun, IMT 28,0 ± 1,1 kg/m2 dan 27,2 ± 1,4 kg/m2. Jumlah asupanenergi total subyek KP 1130,9 ± 221,9 kkal/hari lebih tinggi signifikan (p = 0,02)daripada KK 1024,3 ± 269,9 kkal/hari. Karbohidrat sederhana pada KP (35,6(8,3−69,9)) g/hari lebih tinggi signifikan dibandingkan KK (13,8 (3,4−55,5))g/hari. Asupan serat subyek belum mencukupi anjuran (20–35 g/hari), yaitu KP17,2 ± 2,8 g/hari dan KK 8,6 (5,2−15,2) g/hari walaupun dengan suplementasiPH. Asupan protein, lemak total, dan kolesterol dalam rentang yang dianjurkan,tetapi tidak pada asupan asam lemak tak jenuh tunggal dan jamak. Penurunankadar apo B pada KK (-6,1 ± 8,9 mg/dL) lebih besar tidak signifikan (p = 0,13)dibandingkan pada KP (-1,3 ± 7,3 mg/dL). Dari penelitian ini disimpulkansuplementasi PH 8,4 g/hari dan DRKS 1200 kkal/hari selama 4 minggu tidaklebih baik dalam menurunkan kadar apo B dibandingkan plasebo dan DRKS 1200kkal/hari penyandang obes I. ABSTRACT This double blind randomized clinical trial aims to investigate the change of apoB level in obese I after given supplementation psyllium husk (PH) 8.4 g/day andlow-calorie balanced diet (LCBD) for 4-weeks. By study criteria, 31 subjects wererandomly allocated to one of two groups; 15 subjects for treatment (T) group and16 subjects for plasebo (P) group. The T subjects received psyllium husk (PH) 8.4g/day and LCBD 1200 kcal/day and the P subjects received placebo and LCBD1200 kcal/day. Data collected in this study consist of subject distribution andcharacteristic, intake of energy, macronutrient, fiber, water and apo B level thatassessed before and after treatment. Level of statistical analyses significance was5%, independent t-test and Mann-Whitney. A total 28 subjects (14 subjects ineach group) had completed the intervention. There were no serious adverse eventswere reported along the intervention. Mean of age in T and P groups respectivelywas 35.0 (30.0−45.0) years and 34.5 (30.0−48.0) years, and BMI was 28.0 ± 1.1kg/m2 and 27.2 ± 1.4 kg/m2. The energy intake in T group 1130.9 ± 221.9 kcal/daywas significantly higher (p = 0.02) than P group 1024.3 ± 269.9 kcal/day. Simplecarbohydrate intake in T group (35.6 (8.3−69.9) g/day) was significantly higher (p<0.000) than in P group (13.8 (3.4−55.5) g/day). Intake of dietary fiber in T groupwas 17.2 ± 2.8 g/day had significantly higher than P group 8.6 (5.2−15.2) g/day,even adding PH supplementation cannot meet the recommendation of fiber intake(20-35 g/day). Intake protein and fat in both groups was meet recommendation,differ for intake of mono and polyunsaturated fatty acids. Decreasing of apo Blevel in P group was -6.1 ± 8.9 mg/dL that statistically insignificant difference (p= 0.13) with T group -1.3 ± 7.3 mg/dL. As a conclusion in this study shows, thatPH supplementation 8.4 g/day and LCBD 1200 kcal/day in obese I for 4 weekswasn’t proven to decrease the apo B level. |
