"Prevalensi obesitas cenderung meningkat di berbagai belahan dunia sehingga dapat meningkatkan risiko kardiometabolik pada berbagai penyakit. Salah satu tata laksana obesitas yang paling efektif adalah modifikasi gaya hidup, yaitu pengaturan diet. Penelitian ini merupakan studi pendahuluan dengan desain uji klinis acak tersamar ganda, paralel, dua kelompok, bertujuan mengetahui pengaruh suplementasi serat larut dan diet rendah kalori seimbang (DRKS) selama 4 minggu berturut-turut terhadap berat badan (BB), kadar kolesterol highdensity lipoprotein (HDL) dan trigliserida (TG) serum pada subyek obes I usia 30-50 tahun. Berdasarkan kriteria inklusi, didapatkan 31 subyek yang dibagi menjadi dua kelompok, 15 orang kelompok perlakuan (KP) mendapat DRKS 1200 kkal/hari dan psyllium husk (PH) 8,4 g/hari, dan 16 orang kelompok kontrol (KK) mendapat DRKS 1200 kkal/hari dan plasebo. Sebanyak 28 subyek menyelesaikan penelitian ini. Suplementasi PH ditoleransi dengan baik dan tidak ada efek samping yang serius. Jumlah asupan energi total subyek KP 1130,9 ± 221,9 kkal/hari lebih tinggi signifikan (p = 0,02) daripada KK 1024,3 ± 269,9 kkal/hari. Asupan serat subyek rendah; KP 17,2 ± 2,8 dan KK 8,6 (5,2−15,2) g/hari, walaupun dengan suplementasi PH. Penurunan BB dan peningkatan kadar kolesterol HDL serum sedikit lebih banyak tidak signifikan pada KP (-1,8 ± 0,8 kg dan 0,0 ± 4,3 mg/dL) dibandingkan KK (-1,6 ± 0,9 kg dan -0,4 ± 5,9 mg/dL). Penurunan kadar TG serum KP -1,5 (-416−77) mg/dL lebih rendah tidak signifikan dibandingkan dengan KK -10,0 ± 31,3 mg/dL. Pada penelitian ini belum dapat dibuktikan suplementasi PH 8,4 g/hari dan DRKS 1200 kkal/hari dibandingkan DRKS 1200 kkal/hari saja selama 4 minggu berturut-turut lebih baik dalam menurunkan BB dan mempengaruhi kadar kolesterol HDL dan TG serum pada subyek obes I.

The prevalence of obesity has been increasing globally, thus it likewise made an escalation the risk of cardio metabolic diseases. One method to encounter obesity is lifestyle modification such as the diet. This research was a preliminary study with double blinded randomized clinical trial, parallel, two groups, aims to understand the effects of soluble fiber suplementation and low calorie balanced diet (LCBD) on weight, high-density lipoprotein (HDL) cholesterol and triglycerides serum for obese I subjects age 30-50 years, for four weeks successively. Base on inclusion criteria, 31 subjects are divided into two groups, 15 subjects for treatment (T) receive 1200 kcal/day of LCBD and 8,4 g/day of psyllium husk (PH) and 16 subjects for control (C) receive 1200 kcal/day of LCBD and placebo. 28 subjects accomplish this research. PH suplement were being tolerate decently, and no serious side effect developed. Total energy intake from all T subjects were 1130,9 ± 221,9 kcal, significantly higher (p = 0,02) than C subjects 1024,3 ± 269,9 kcal/day. Subjects intake of fibers were low, even adding PH supplementation; 17,2 ± 2,8 for T subjects and 8,6 (5,2-15,2) g/day for C subjects. Weight loss and HDL cholesterol serum level enhancement were insignificantly higher on T subjects (-1,8 ± 0,8 kg and 0,0 ± 4,3 mg/dL) compared to C subjects (-1,6 ± 0,9 kg and -0,4 ± 5,9 mg/dL). TG serum level derivation on T subjects are -1,5 (-416−77) mg/dL insignificantly lower than C subjects -10,0 ± 31,3 mg/dL. This research has still yet able to prove that suplementation of PG 8,4 g/day and LCBD 1200 kcal/day in compare to only 1200 kcal/day of LCBD and placebo in 4 weeks consecutively are better in weight loss and affect the level of HDL cholesterol and TG serum on obese I subjects."

Objective: to determine the metabolic state of obese females after treatment with balanced low-calorie diet for 14 days by measuring resting energy expenditure (REE) and serum T3 level as indicators.

Location : Sumber Waras hospital , West Jakarta

Methods : The study was carried out on 37 obese females who have been recruited based on inclusion and exclusion criteria. This study is a quasi experimental study with a pre and posttest treatment design. Every subject received a balanced low-calorie diet (LCD) of 1000 kcal/day for 14 days. Antropometric measwrements, REE and serum T3 levels were examined at the beginning, at day 7 and at the end of study. REE were measured and calculated by indirect calorimetry (measured-REE) and using Harris-Benedict equation (calculated-REE) respectively.

Result : Balanced LCD given for 14 days significantly (p <0.05) decreased body weight (BW) , fat mass, fat free mass, measured-REE and calculated-REE from 71.22±8.63 kg to 69.15±8.37 kg (decreased 2,9%), from 35.32.58% to 33.94±2.58% (1,38%), from 45.96±4.89 kg to 45.54±4.82 kg (0,92%), from 1815.0822.37 kcal to 1718.97±269.50 kcal (5,29%), and from 1428,.7±84.02 kcal to 1408.25±81.52 kcal (1,39%) respectively. There was a significant decrease (p = 0.001) in serum T3 leveI at day 7 from 0.9005±0.1530 ng/mL to 0.836210.1611 nglmL (decrease 7,1%). At the end of the study, serum T3 levels increased not significantly compared to day 7. At day 7, there was a significant positive correlation (r = 0.349; p = 0.034) between the change in measured-REE and the change in serum T3 levels. At day 15, a significant positive correlation (r = 0.401; p = 0.014) was found between the change in measured-REE and the change in fat free mass. The changed of serum T3 levels at day 7 had significant positive correlation (r = 0,385; p = 0,019) with the changed of BW in the first week. The changed of serum T3 levels at day 7 had significant positive correlation (r = 0,345; p = 0,036) with the changed of fat free mass in the first week. After reduction of BW by 2.9%, there was a decrease of measured-REE and calculated-REE, 5.29% and 1.39%, respectively. The measured-REE was 27% higher than calculated-REE.

Conclusion : Weight-reduced obese subjects with balanced LCD were in hypometabolic state indicated by a reduction in measured and calculated-REE, and serum T3 levels."

"Uji klinis acak tersamar ganda paralel ini merupakan penelitian pendahuluan, bertujuan mengetahui pengaruh suplementasi serat larut dan diet rendah kalori seimbang (DRKS) selama 4 minggu terhadap kadar kolesterol low-density lipoprotein (LDL) serum pada obes I usia 30−50 tahun. Sejumlah 31 subyek dipilih dengan kriteria tertentu dan dibagi menjadi dua kelompok dengan randomisasi blok, 15 orang kelompok perlakuan (KP) dan 16 orang kelompok kontrol (KK). Subyek KP mendapat serat larut psyllium husk (PH) 8,4 g/hari dan DRKS 1200 kkal/hari, sedangkan subyek KK mendapat plasebo dan DRKS 1200 kkal/hari. Data terdiri atas usia, indeks massa tubuh (IMT), asupan zat gizi, serta kadar kolesterol LDL serum. Pemeriksaan kolesterol LDL dilakukan pada awal dan akhir penelitian. Analisis data menggunakan uji t tidak berpasangan dan Mann-Whitney, batas kemaknaan 5%. Karakteristik data dasar dan sebaran subyek kedua kelompok sebanding. Analisis lengkap dilakukan pada 28 subyek (KP dan KK masing-masing 14 subyek). Suplementasi ditoleransi baik dan tidak ditemukan efek samping serius. Median usia subyek KP dan KK berturut-turut 35,0 (30−45) tahun dan 34,50 (30−48) tahun serta rerata IMT 28,0 ± 1,1 kg/m2 dan 27,2 ± 1,4 kg/m2. Rerata kadar kolesterol LDL serum awal KP 137,0 ± 37,0 mg/dL dan KK 134,4 ± 29,1 mg/dL. Defisit energi KP lebih rendah tidak signifikan (p = 0,62) dibandingkan KK, berturut-turut -282,0 ± 482,6 kkal/hari dan -331,8 ± 578,3 kkal/hari. Persentase asupan energi terhadap anjuran KP (94,2 ± 18,5%) lebih tinggi signifikan (p = 0,02) daripada KK (85,4 ± 22,9%). Asupan karbohidrat (KH) total KP (613,1 ± 134,5 kkal/hari) lebih tinggi signifikan (p = 0,02) dibandingkan KK (545,4 ± 161,1 kkal/hari). Asupan protein, lemak total, dan kolesterol KP dan KK sesuai rekomendasi NCEP-ATP III. Pada kedua kelompok, asupan asam lemak jenuh cenderung tinggi, tetapi asupan asam lemak tak jenuh tunggal dan jamak rendah. Asupan serat subyek KP 17,2 ± 2,8 g/hari dan KK 8,6 (5,2−15,2) g/hari. Dengan suplementasi PH tidak tercapai rekomendasi asupan serat. Persentase asupan KH sederhana terhadap energi total KP 11,5±5,4% lebih tinggi signifikan (p = 0,00) dibandingkan KK 6,0 (1,2524,2)%. Penurunan kadar kolesterol LDL serum KP -2,1 ± 16,2 mg/dL lebih sedikit tidak signifikan (p = 0,15) dibandingkan pada KK -10,9 ± 15,3 mg/dL. Penelitian ini belum dapat membuktikan suplementasi PH 8,4 g/hari dan DRKS 1200 kkal/hari selama 4 minggu lebih baik dalam menurunkan kadar kolesterol LDL serum dibandingkan plasebo pada subyek obes I.

This parallel double blind randomized clinical trial is a preliminary study that aims to investigate the effect of soluble fiber supplementation 8.4 g/day and lowcalorie balanced diet (LCBD) for 4 weeks on serum low-density lipoprotein (LDL) cholesterol level in obese I, aged 30−50 years old. A total of 31 subjects were selected using certain criteria and randomly allocated to one of two groups using block randomization; 15 subjects for treatment (T) group and 16 subjects for control (C) group, respectively. The T group received psyllium husk (PH) 8.4 g/day and LCBD 1200 kcal/day, and the C group received placebo and LCBD 1200 kcal/day. Data include age, body mass index (BMI), intake of energy, macronutrient, and fiber, as well as serum LDL cholesterol level. Serum LDL cholesterol level was examined before and after treatment. Statistical analyses include independent t-test and Mann-Whitney with significance level of 5%. Subjects characteristics of the two groups at baseline was not statistically different. Twenty eight subjects (14 subjects in each group) completed the intervention. Supplementation was well tolerated and there were no serious adverse events. The mean age in T and C group was 35.0 (30.0−45.0) and 34.5 (30.0−48.0) years, respectively, and BMI was 28.0 ± 1.1 and 27.2 ± 1.4 kg/m2, respectively. The pretreatment serum LDL cholesterol level in T and C group was 137.0 ± 37.0 and 134.4 ± 29.1 mg/dL, respectively. Energy deficit in T group was insignificantly lower (p = 0.62) than in C group; -282.0 ± 482.6 and -331.8 ± 578.3 kcal/day, respectively. Percentage of energy intake to recommendation in T group (94.2 ± 18.5%) was significantly higher (p = 0.02) than that in C group (85.4 ± 22.9%). Total carbohydrate (CHO) intake in T group (613.1 ± 134.5 kcal/day) was significantly higher (p = 0.02) than in C group (545.4 ± 161.1 kcal/day). Total protein, fat, and cholesterol intake were similar to the NCEP-ATP III recommendation in both groups. Intake of SAFA was higher than recommended, meanwhile PUFA and MUFA intake were lower than those recommended in both groups. Dietary fiber intake in T and C group was 17.2 ± 2.8 and 8.6 (5.2−15.2) g/day, respectively. During the intervention, PH supplementation did not meet the recommendation. Percentage of simple CHO to total energy in T group 11.5±5.4% was significantly higher (p = 0.00) than in C group 6.0 (1.2524.2)%. PH supplementation decreased serum LDL cholesterol level (-2.1 ± 16.2 mg/dL) lower than placebo (-10.9 ± 15.3 mg/dL), but not significant different (p = 0.15). This study shows that PH supplementation 8.4 g/day in combination with LCBD 1200 kcal/day for 4 weeks in obese I aged 30−50 years old is not proven to decrease the serum LDL cholesterol level."

"Leptin yang diketemukan oleh Zhang dan Friedman pada tahun 1994, dihasilkan oleh adiposit dan berhubungan dengan obesitas. Pada hewan coba, selain mempengaruhi homeostasis berat badan, leptin juga mempengaruhi metabolisme lipid pada jaringan perifer, seperti lipolisis dan lipogenesis. Peningkatan lipolisis dan penurunan lipogenesis menyebabkan peningkatan asam lemak bebas, yang kemudian diikuti oleh peningkatan konsentrasi trigliserida. Pada saat konsentrasi trigliserida tinggi, terjadi pembentukan small dense LDL, yang merupakan komponen dari dislipidemia aterogenik, terutama pada individu obes. Penelitian ini berusaha memperlihatkan perbedaan antara konsentrasi leptin dan profil lipid pada obes dan non-obes, dan terdapatnya hubungan antara leptin dan small dense LDL pada obesitas.Subyek: Berhasil dikumpulkan 297 laki-laki subyek penelitian, yang terdiri dari 205 subyek dengan obesitas sentral dan 92 subyek non-obes, yang presentase terbesar berusia antara 30-59 tahun. Variabel yang diamati pada penelitan ini antara lain, Indeks Massa Tubuh (IMT), lingkar perut, konsentrasi leptin, trigliserida, asam lemak bebas, kolesterol LDL, ApoB, ratio kolesterol LDL dan ApoB, kolesterol HDL, glukosa puasa dan insulin.Metodologi: Penelitian ini menggunakan disain potong lintang, Hubungan antara leptin dengan variabel-variabel seperti IMT, lingkar perut, leptin, trigliserida asam lemak bebas, kolesterol LDL, ApoB, kolesterol HDL dan insulin dianalisis dengan unpaired Nest, dibandingkan antara kelompok obes sentral dan non-obes. Sedangkan hubungan antara leptin dan small dense LDL dianalisis dengan menggunakan regresi logistik.Pemeriksaan laboratorium dari tiap variabel dilakukan dengan metode antara lain, konsentrasi trigliserida dan asam lemak bebas diukur dengan metode kolorimetri enzimatik, kolesterol LDL dan kolesterol HDL diukur dengan metode homogenisasi. Konsentrasi insulin diukur dengan metode ELISA, kadar leptin diukur dengan metode immunoassay.Hasil dan Pembahasan: Terdapat perbedaan karateristik antara kelompok obes dan non-obes, antara lain plasma leptin lebih tinggi pada kelompok obes sentral dibandingkan dengan kelompok normal; 9,71 (1,92) ng/mL vs. 2,63 (2,09) ng/mL, (P<0,001); rerata trigliserida 159,1 (6,97) mg/dL vs. 119,4 (4,8) mg/dL; (P<0,001), asam lemak bebas 0,42 (0,01) mmol/L vs. 0,36 (0,02) mmol/L; (p=0,001), apoB 108,05 (21,1) mg/dL vs. 101,4 (20,4) mg/dL(p=0,012) juga lebih tinggi pada kelompok obes dibandingkan non-obes, kolesterol HDL lebih rendah pada kelompok obes yaitu 40,6 (1,2) mg/dL vs. 46,2 (1,2) mg/dL; (P<0,001). Sedangkan rerata kolesterol LDL tidak berbeda bermakna antara kelompok obes dan non-obes 138,9 (32,2) mg/dL vs. 137,8 (31,9) mg/dL; (P=0,792). Pada subyek dengan Inleptin < 7,5 pg/mL (1,8 ng/mL) peningkatan kemungkinan didapatkannya small dense LDL sebesar 5,92 kali dibandingkan dengan subyek dengan lnleptin > 9,87 pg/mL (19,34 ng/mL).Penentuan indeks massa tubuh sebagai kriteria obesitas; penelitian ini memperkuat pendapat untuk menggunakan kriteria Asia Pasifik (1MT > 25 kg/m2) sebagai klasifikasi indeks massa tubuh (IMT) untuk populasi orang Indonesia.Hubungan lingkar perut dengan small dense LDL, leptin, IMT, dan HOMA-IR; Lingkar perut mempunyai korelasi yang baik dan bermakna secara statistik dengan konsentrasi leptin (r=0,72 dan P<0,05) dan HOMA-IR (r~0,53 dan P<0,05). Lingkar perut pada subyek dengan dan tanpa small dense LDL berbeda bermakna (P=0,016).Nilai normal konsentrasi leptin bagi IMT normal adalah 2,04 ng/mL dengan kisaran: 0,45 - 9,26 ng/mL. dan rerata konsentrasi leptin pada subyek obes sentral adalah 9,71 ng/mL dan subyek non-obes : 2,63 ng/mL.Resistensi dan defisiensi leptin pada obesitas; pada obesitas sentral dapat terjadi resistensi leptin atau defisiensi leptin dan mungkin ambang terjadinya resistensi leptin pada subyek penelitian ini lebih rendah (< 20 ng/mL) dibandingkan etnik Kaukasia.Peran enzim lipase hepatik (HL) pada pembentukan small dense LDL; hubungan peningkatan konsentrasi leptin dengan didapatkannya small dense LDL dapat dihubungkan dengan efek enzim lipase hepatik. Bila pengaruh leptin terhadap didapatkannya small dense LDL terjadi dengan bantuan enzim lipase hepatik (HL) sebagai katalisator dapat dibuktikan, maka akan memperkuat bukti adanya hubungan antara leptin dengan didapatkannya small dense LDL.Hipotesis baru penelitian ini adalah, leptin mempunyai efek inhibisi terhadap enzim lipase hepatik di hati, atau analog dengan efek inhibisi insulin terhadap enzim HSL pada adiposit.Hasil penelitian dibandingkan dengan penelitian lipid sebelumnya; hasil penelitian ini dapat membuktikan perbedaan leptin dan profil lipid, yaitu konsentrasi asam lemak bebas, trigliserida dan kolesterol HDL pada kelompok subyek obesitas sentral dan subyek non-obes. Beberapa penelitian sebelumnya memberikan hasil yang berbeda.Simpulan: Penelitian ini adalah penelitian pertama yang membandingkan konsentrasi leptin dan hubungannya dengan small dense LDL pada kelompok obes dan non-obes pada populasi di Indonesia maupun di dunia. Hasil penelitian ini memperlihatkan bahwa konsentrasi leptin lebih tinggi secara bermakna pada kelompok obes sentral dibandingkan dengan kelompok non-obes, serta berhubungan secara bermakna dengan konsentrasi trigliserida, asam lemak bebas, apoB dan kolesterol HOL. Lebih jauh lagi, penelitian ini juga memperlihatkan hubungan antara leptin dan didapatkannya small dense LDL, di mana makin rendah leptin akan makin meningkatkan kemungkinan terdapatnya small dense LDL, Pada laki-laki dengan obesitas sentral, leptin berhubungan dengan prediksi didapatkannya small dense LDL. Leptin secara independen mempunyai efek protektif terhadap didapatkannya small dense LDL.

Background: Leptin which is discovered by Zhang and Friedman (1994) is secreted by adipocytes and associated with obesity. In animals it has been shown that beside its effect on weight homeostasis, leptin also exerts peripheral effects that include lipid metabolism, i.e. lipogenesis and lipolysis. The results of studies on humans are conflicting. The increased lipolysis and decreased lipogenesis resulted in an increase synthesis of fatty acids which is followed by triglycerides. At a certain level of triglycerides, small dense LDL formation occur, an established component of atherogenic lipoprotein phenotype (ALP). Leptin has been implicated in this process especially in central obese individuals. The aim of the study is to show that leptin and lipid levels are higher in central obese as compared to non-obese individuals and to investigate the relationship between leptin levels and small dense LDL in central obese individuals.

Subjects: A total of 297 male subjects comprising 205 central obese and 92 nonobese age 30-59 years were enrolled in the study. Variables under study includes body mass index (BMI), serum leptin, triglyceride, free fatty acids, LDL-cholesterol, apoB, LDL-cholesterollapoB ratio, HDL-cholesterol and insulin levels.

Methods: This is a cross sectional study. The correlation between leptin and some variables, such as body mass index (BMI), triglycerides, free fatty acids, LDL-cholesterol, apoB, LDL-cholesterollapoB ratio, HDL-cholesterol and insulin levels was analyzed by unpaired t-test. Correlation between leptin and small dense LDL was analyzed by logistic regression. Plasma tryglycerides and free fatty acids were measured by enzymatic colorimetry method; apoB by immunoturbidimetry, LDL-cholesterol and HDL-cholesterol by homogenous method, insulin level by enzym-linked immunosorbent assay (BLISA), Plasma leptin was measured by immunoassay.

Results & Discussion: The characteristics between obese and nonobese subjects were different, such as mean plasma leptin levels were significantly higher in central obese than in nonobese individuals 9.71 (1.92) ng/mL vs. 2.63 (2.09) ng/mL, (P<0.001); mean triglycerides 159.1 (6.97) mg/dL vs. 119.4 (4.8) mg/dL; (P<0.001), free fatty acids 0.42 (0.01) mmol/L vs. 0.36 (0.02) mmol/L; (P=0.001), apoB 108.05 (21.1) mg/dL vs. 101.4 (20.4) mg/dL (P=0.012) were also higher in central obese than in nonobese individuals, and HDL-cholesterol is lower 40.6 (1.2) mg/dL vs. 46.2 (1.2) mg/dL; (P<0.001). LDL-cholesterol 138.9 (32.2) mg/dL vs. 137.8 (31.9) mg/dL (P=0.792). Among subjects with lnleptin < 7.5 pg/mL (L8 ng/mL) the risk of having small dense LDL increases by 5.92 times compared to subjects with lnleptin 9.87 pg/mL (19.34 ng/mL).

In regard to body mass index and the classification of obesity, the present study is in favor with the Asia Pacific classification and criteria for obesity, i.e. BMI > 25 kg/rn2 to be used for Indonesian population.

Relationship between waist circumferences, small dense LDL, leptin, BMI, dan HOMA-IR. There is a statistically significant strong relationship between waist circumference and leptin (r=0.72; P<0.05) and HOMA-IR P<0.05). Furthermore, mean of waist circumference differ significantly between subjects with and without small dense LDL (P=0.016).

Normal leptin levels for subjects with normal BMI is 2.04 ng/mL (range 0.45-9.26 ng/mL); and mean leptin levels for obese and nonobese were 9.71 and 2.63 ng/mL, respectively.

In regard to leptin resistance and leptin deficiency in obese subjects. Both leptin resistance and leptin dificiency is found in obese subjects, and the result indicate that leptin resistance in this population developed at lower leptin level (<20 ng/mL) as compared to Caucasian.

The possible role of hepatic lipase in small dense LDL formation. The relationship of increased leptin levels and the presence of small dense LDL could possibly be due to hepatic lipase (HL) effect. If the effect of leptin on small dense LDL formation is by way of HL as catalysator can be proven, this finding will then support the evidence of relationship between leptin and small dense LDL.

The hypothesis generated from the present study is that leptin inhibits the effect of HL in the liver in analogy with the inhibitory effect of insulin on HSL in the adipocyte.

Results arising from the present study support the view that leptin levels and lipid profile, i.e. free fatty acids, triglycerides, dan HDL cholesterol in obese differ from nonobese subjects, whereas other studies give different results.

Conclusion: This is the first study that compare leptin levels and determine the relationship between leptin and small dense LDL in central obese and nonobese male Indonesian subjects. The results showed that leptin levels are significantly higher in central obese as compared to nonobese individuals, and is correlated with triglycerides, free fatty acids, apoB and HDL-cholesterol in central obese individuals. Furthermore, this study also showed a relationship between leptin levels and small dense LDL in central obese individuals, in which lower leptin levels carries a higher probability of having more small dense LDL. Leptin has an independent protective effect for the occurrence of small dense LDL."

Background: Obesity is now a global epidemic problem. Increased prevalence of obesity is associated with increased sedentary behaviour and low physical activity. Research on differences in physical activity pattern in obese and nonobese adolescents have varying results. Research on this is very rare in Indonesia. Purpose: Knowing the physical activity patterns of adolescents aged 10-15 years old and know the difference between the mean energy output, physical activity intensity and duration of physical activity of moderate-vigorous intensity, and screen time obese and non-obese adolescents and determine the suitability of adolescents physical activity with recommendation. Method: Cross sectional study conducted on 6th and 7th grade students aged 10- 15 years old in 216 Junior High Schools. The study consisted of 2 phases. The first stage to see the physical activity patterns of adolescents aged 10-15 years, while the second stage to see the difference in mean energy output, intensity of physical activity, duration of physical activity of moderate-vigorous intensity, and screen time obese and non-obese adolescents. Physical activity was assessed using Bouchard diary for 2 days school and 1 day off. Results: School working, watching TV, walking, swimming, and football is a physical activity that is often done by adolescents. There was no difference in energy output between obese and non-obese adolescents (median 4752.9 (2950 to 8065.8) vs. 4435.4 (2753.4 to 8134.7) kcal / day, p 0.160). The intensity of physical activity of obese adolescents is lower than non-obese adolescents (median 1.5 (0.8 to 1.8) vs 2 (1.6 to 2.8) METs, p <0.001). Duration of physical activity of moderate-vigorous intensity obese adolescents shorter than non-obese adolescents (19.3 ± 6.9 vs 26.4 ± 3.4 minutes, p 0.000). Screen time obese adolescents longer than non-obese adolescents (median 2.8 (1 to 6.6) vs 1.8 (0.3 to 6.1) hours, p 0.000). There were no adolescents who meet recommendation based on the intensity and duration of physical activity criteria, 15.5% obese adolescent and 79.8% non-obese adolescents meet recommendations based on screen time (p, 0.001). Conclusion: Physical activity varies among adolescents age 10-15 years old. There are no difference in mean energy output but there are differences in intensity of physical activity, duration of physical activity of moderate-vigorous intensity, and screen time between obese and non-obese adolecents. Most of adolescents physical activity are not appropriate with recommendation."
