Nutrition education can contribute to maintaining health and optimal learning capacities during childhood. One important aspect to achieve goals and have successful nutrition education in schoolchildren is the quality of nutrition educators. This study aims to assess the effectiveness of online nutrition educator training to improve knowledge, attitudes, and self-efficacy in giving nutrition education and overcoming barriers in nutrition education due to the Covid-19 pandemic. This was a quasi-experimental study with one group pretest-posttest design, including seventy-three nutrition educators. Nutrition educators derived from nutrition students/alumni and was recruited online by interviews. Intervention was done in terms of one-time online education by the experienced lecturers. Knowledge regarding reducing salt, sugar and fat consumption was retrieved from 20 multiple choice questions. Self-efficacy was assessed using a self-developed questionnaire. From this study, intervention for nutrition educators significantly increased educators’ knowledge by 3 points from 82 to 85 (p<0.01) and improved self-efficacy was significant for 1-time and 3-times per week. Nutrition educators perceived that the best duration to do nutrition education related to reduction of sugar, salt and fat among schoolchildren was 3 times/week, for 30 minutes per meeting. Higher self-efficacy was found in giving offline than online nutrition education. Crowded places, bad weather, a conducive environment, and educators’ bad health become barriers to nutrition educators in providing nutrition education. Nutrition educators are having more self-efficacy in giving nutrition education using power-points (p <0.001) rather than through video or games in online based-nutrition education for schoolchildren. This study succeeded in providing significant results on the effectiveness of one-day training in improving the nutrition educators’ knowledge, attitude, and self-efficacy.

Terdapat 30 pertanyaan terkait pengetahuan, sikap dan tindakan pencegahan anemia yang diberikan kepada responden yang terpilih secara acak. Analisis deskriptif dilakukan untuk melihat sebaran remaja berdasarkan variabel yang diukur. Analisis bivariat dengan uji Spearman dilakukan untuk mengetahui hubungan antara pengetahuan serta sikap dengan tindakan.Hasil: Pengetahuan tentang anemia masih rendah, dimana 65,3% responden berpengetahuan cukup dan 34,7% berpengetahuan baik. Mayoritas responden memiliki sikap positif (97,3%) terhadap anemia dan pencegahannya, namun 2,7% masih memiliki sikap negatif. Sebagian besar responden juga belum melaksanakan tindakan pencegahan anemia dengan baik (86,7%), di mana hanya 13,3% yang memiliki tindakan baik. Pengetahuan tidak berkorelasi dengan tindakan (p>0,05) sementara sikap berkorelasi dengan tindakan (p<0,05).Kesimpulan: Remaja putri dalam konteks penelitian ini masih mempunyai pengetahuan dan tindakan yang kurang baik terhadap anemia serta pencegahannya, meskipun sikap mereka cenderung dominan positif. Upaya edukasi dan pendekatan promotif lainnya perlu ditingkatkan untuk mendorong terjadinya perubahan perilaku di kalangan remaja putri.
