"Asam lemak omega-3 merupakan komponen penting pada pembentukan sel saraf, retina dan membran sel. Penelitian terakhir menunjukkan bahwa asam lemak omega-3 berkaitan dengan pertumbuhan janin. Ibu hamil dengan asupan asam lemak omega-3 yang tidak tercukupi memiliki risiko lebih tinggi untuk melahirkan bayi berat lahir rendah (BBLR). Di Indonesia, angka BBLR masih tergolong tinggi. Oleh karena itu, kecukupan asam lemak omega-3 sangat penting untuk diperhatikan pada ibu hamil sejak awal kandungan. Penelitian ini bertujuan untuk mengetahui kecukupan asam lemak omega-3 ibu hamil di Indonesia. Desain penelitian yang digunakan adalah studi potong lintang. Subjek penelitian merupakan ibu hamil sehat dengan usia gestasi hingga 20 minggu. Kecukupan dinilai melalui pendataan asupan asam lemak omega-3, omega-6 beserta rasionya dan pemeriksaan kadar asam lemak omega-3 membran eritrosit. Data penelitian kemudian dianalisis dengan uji korelasi Spearman. Hasil penelitian menunjukkan bahwa asupan asam lemak omega-3 total subjek penelitian masih kurang akibat rendahnya rerata asupan ALA subjek, meskipun rerata asupan EPA dan DHAnya telah terpenuhi. Asupan asam lemak omega-6 total subjek telah terpenuhi, begitu pula dengan asupan LAnya, tetapi asupan AA subjek masih belum terpenuhi. Rasio asupan asam lemak omega-6/omega-3 sebagian besar subjek masih kurang baik. Dari uji korelasi ditemukan adanya korelasi positif bermakna antara asupan EPA dengan kadar DHA (r=0,34) dan kadar EPA+DHA (r=0,38), asupan DHA dengan kadar DHA (r=0,31), asupan EPA+DHA dengan kadar DHA (r=0,34) dan kadar EPA+DHA (r=0,35). Rasio asupan asam lemak omega-6/omega-3 ditemukan memiliki korelasi negatif bermakna dengan kadar EPA (r= ?0,34). Berdasarkan hasil penelitian tersebut dapat disimpulkan bahwa asam lemak omega-3 ibu hamil belum tercukupi sehingga diperlukan edukasi dan screening kecukupan asupan asam lemak omega-3 bagi ibu hamil sejak awal kandungan.

Omega-3 fatty acids are important components of neural, retinal and cell membranes. Latest findings show that omega-3 fatty acids play a role in fetal growth. Pregnant women with low intakes of omega-3 fatty acids were found to have higher risk of low birth weight (LBW). In Indonesia, LBW prevalence is still high. Thus omega-3 fatty acids sufficiency is of great importance starting early in pregnancy. The aim of this study is to determine omega-3 fatty acids status of pregnant women in Indonesia. The design of the study is cross-sectional. Subjects are healthy pregnant women with gestational age up to 20 weeks pregnancy. Omega-3 fatty acids status obtained from interview on intakes of omega-3 fatty acids and level of omega-3 fatty acids in erythrocyte membrane. The data?s then analyzed using Spearman correlation test. The study results show that total omega-3 fatty acids intakes are insufficient, due to low ALA intake, even though EPA and DHA intakes are sufficient. Intakes of total omega-6 fatty acids and LA are sufficient but AA intake is very low. The ratio of omega-6/omega-3 fatty acids intake is found to be higher than expected. Spearman correlation test shows significant positive correlations between intake of EPA and DHA level (r=0.34), intake of EPA and EPA+DHA level (r=0.38), intake of DHA and its level (r=0.31), intake of EPA+DHA and DHA level (r=0.35), intake of EPA+DHA and its level (r=0.34). Ratio of omega-6/omega-3 fatty acids intake is found to be significantly correlated with EPA level (r=?0.34). In conclusion, omega-3 fatty acids intake of pregnant women in Indonesia is still insufficient. Therefore, education to increase omega-3 fatty acids intake during pregnancy and screening of omega-3 fatty acids intake need to be perform early in pregnancy."

Dietary intake of omega-3 fatty acids (FAs) is important during pregnancy and influence birth outcome. Limited published study in Indonesia related to dietary omega-3 FAs intake among pregnant women and its association with infant birth size. A cross-sectional study was designed among registered antenatal care and >32 weeks of gestational age pregnant women in all sub-district public health centers in East Jakarta.

Structured interview, semi-quantitative food frequency questionnaire (SQFFQ), shorrboard, and HemoCue were used to assess maternal factors, usual intake of omega-3 FAs, measure anthropometric and hemoglobin level data respectively. Mid-upper arm circumference (MUAC) SECA tape, pediatric weighing scale and medical record were used to assess infant head circumference, birth weight and length, respectively.

Multivariate analysis was used to find adjusted association between omega-3 FAs intake and birth size. Pregnant women with fat intake below 54.27 mg/d would have 2.1 (95% CI: 1.16-4.03) times higher risk to have sub normal head circumference while pregnant women with alpa-linolenic acid (ALA) intake below 0.82 gram/d would have 95 (95%CI: 9.3-180) gram lower birth weight in adjusted data. None of omega-3 fatty acids was associated with birth length. Fat and ALA had association with head circumference and birth weight, respectively."

Bifidobacterium colonization in neonates is crucial because it has a large effect on their health and immunity in the future, thus factors that influenced the maternal gut Bifidobacterium became important to known because maternal gut Bifidobacterium is the most important factor to determined the initial colonization. Dietary intervention studies have shown that high fat diet can dramatically changed the nurmbers of gut Bifidobacterium.

The aim of this study was to examine the correlation between total dietary fat intake and the ratio of essential fatty acids with the numbers of maternal gut Bifidobacterium on third trimester of pregnancy. Fifty two pregnant women (33?37 weeks) from 10 district primary health care in East Jakarta were enrolled in this cross sectional study. Dietary fat intake and the ratio of essential fatty acids was assesed with 2-day repeated 24 hours food recall and SQFFQ, respectively. Maternal gut Bifidobacterium was analysed by quantitative real-time PCR.

This present study have shown that total dietary fat intake have a weak positive correlation with maternal gut Bifidobacterium in third trimester of pregnancy. Hormonal and immunological changes in pregnancy is the possible explanation to this phenomenon. This study have not been able to prove a correlation between omega-6 to omega-3 fatty acid ratio with maternal gut Bifidobacterium."

Background: Education in the form of counseling is an indespensable part of pediatric obesity management. Omega-3 polyunsaturated fatty acids (PUFA) are beneficial essential nutrients in obesity management, given their effects on lipid homeostasis, specifically by increasing lipid catabolism, decreasing adipogenesis, and modulating appetite. Until now, there is no nutritional recommendation focusing on omega-3 PUFA for overweight and obese children. Linear programming is one method to generate specific nutritional recommendation that also considering the food affordability, availability, and food consumption pattern.

Objective: To investigate the differences of plasma omega-3 PUFA changes between group that received omega-3 PUFA optimized using linear programming dietary counseling and control group with standard counseling.

Method: This study is an open clinical trial with parallel design, 39 children aged 12-24 months with BMI Z score > +1 based on WHO growth curve were randomly assigned by block randomization with stratification into enhanced counseling with omega-3 optimization using linear programming or general counseling group. Both counseling were conducted once weekly for 10 weeks. At baseline and endline, the following parameters were measured: fat intake, omega-3 intake, ratio of omega-6/omega-3 intake, eating behaviour, plasma concentration of omega-3, and plasma omega-6/omega-3 ratio.

Results: After the intervention, α-linolenic acid intake was significantly increased compared to control group (278,011  435,56 vs. -44,498  407,785, p=0,035). There were no significant differences in changes of plasma omega-3 FA between the intervention and control group.

Conclusion: Omega-3 FA optimized dietary counseling using linear programming was partially successful in improving thee variation of omega-3 FA food sources, however there were no significant changes in plasma omega-3 FA."

"Asam lemak omega-3 merupakan asam lemak essensial bagi tubuh manusia. Mikroalga merupakan salah satu sumber asam lemak omega-3 yang sangat prospektif untuk dikembangkan, karena kualitas yang lebih tinggi dibanding sumber asam lemak omega-3 lainnya. Pemanfaatan langsung asam lemak omega-3 dari mikroalga memerlukan biaya produksi lebih tinggi. Sehingga penelitian terkini banyak diarahkan pada studi genetika terhadap enzim yang berperan penting dalam biosintesis asam lemak omega-3, salah satunya adalah enzim omega-3 desaturase. Penelitian ini akan difokuskan pada isolasi dan kloning gen yang mengkode enzim omega-3 desaturase dari mikroalga Nannochloropsis sp. Gradient Polymerase Chain Reaction ( PCR ) berhasil mengamplifikasi gen omega-3 desaturase dengan panjang 489bp. Gen disisipkan pada plasmid T-vector pMD20 dan dikloning pada sel kompeten bakteri Escherichia coli DH5α. Konfirmasi produk kloning melalui colony PCR dan dari hasil konfirmasi berat molekul yang dianalisa menggunakan metode agarose electrophoresis menunjukkan terdapat 6 koloni yang positif mengandung gen omega-3 desaturase. Konfirmasi dengan DNA sequencing masih perlu dilakukan di masa yang akan datang.

Omega-3 fatty acids are essential fatty acids for the human body. Microalgae is one source of omega-3 fatty acids which is highly prospective for development, because it has higher quality than the other sources of omega-3 fatty acids. Direct utilization of omega-3 fatty acids from microalgae requires higher production cost. Therefore, many of the recently studies focus on genetic study for the enzymes which play important role in biosynthesis of omega-3 fatty acids, one of them is omega-3 desaturase enzyme. This research will be focused on the isolation and cloning of gene encoding omega-3 desaturase enzyme from microalgae Nannochloropsis sp. Gradient Polymerase Chain Reaction (PCR) successfully amplified 489bp of omega-3 desaturase gene. The gene was inserted into T-Vector pMD20 plasmid and cloned to Escherichia coli DH5α competent cell. Confirmation cloning product using colony PCR and from molecular weight analyzing by agarose electrophoresis method showed that there are 6 colonies positively content omega-3 desaturase gene.

Osteoarthritis OA is a chronic disease characterized by joint pain, and is a major cause of disability in the patient. One of several factors in the pathogenesis of OA is the generation of oxidative stress, inducing chondrocytes apoptosis due to lipid peroxidation, characterized by the increasing of malondialdehyde MDA level. Omega 3 fatty acids have role in inhibiting the oxidative stress, meanwhile omega 6 hold contradicting role. Both fatty acids are essential in human body, and their levels are determined by the intake from the food sources. The omega 6 omega 3 ratio should be optimal in order to reduce the oxidative stress. This study aims to investigate the association between the ratio of omega 6 omega 3 fatty acids intake to MDA plasma level in patients with knee OA. This was a cross sectional study, conducted at orthopedic clinic at Bhayangkara RS. Sukanto Hospital and Cipto Mangunkusumo Hospital Jakarta, in patients with II IV grade Kellgren Lawrence of knee OA, aged between 40 60 years. The 1 month history of omega 3 and omega 6 intake was obtained by using semi quantitative food frequency questionnaire. The omega 6 omega 3 ratio was calculated by dividing the average daily intake of total omega 6 fatty acids by the average daily intake of total omega 3 fatty acids. The MDA plasma level was measured by spectrophotometry method. Of 57 subjects participated, the mean age was 50 years, 87,7 were female, and mostly 89,5 were obese. The percentage of both fatty acids intake was below the Recommended Dietary Allowance RDA , the median for omega 3 and omega 6 intake were 0,864 0,351 2,200 g day and 6,830 3,066 19,110 g day. Thus the ratio of omega 6 omega 3 intake was 8,8 1, and the mean MDA plasma level was 0,773 0,199 nmol mL. The age, BMI, and physical activity score variables were then controlled through multiple linear regression test. The results found were the increase of 1 unit of omega 6 omega 3 intake ratio would increase MDA level of 0,023 nmol mL 0,023, 95 CI 0,004 ndash 0,042, p 0,017 . A high ratio of omega 6 omega 3 intake is associated with elevated plasma MDA level in knee OA patients. Therefore, a subsequent education is necessary in achieving optimal ratio thus prevent the progressivity of knee OA."
