 Background: The incessant promotion of fast food make a perception that fast food is a trend among teenager.  Fast food consumption habits that have high calorie but low nutrients will causes nutritional problems in adolescents. Objectives: The purpose of this study aimed to determine effect of nutritional education based on theory of planned behavior to change knowledge, attitude, subjective norms, perceived behavioral control, intention, and limited fast food consumption among female students in Sidoarjo. Methods: This study was interventional quasi-experimental research. 32 female students (each 16 female students for interventional group and 16 female students for control group), were selected by simple random sampling. The education was provided based on theory of planned behavior in four sessions. The researcher-made questionnaire based on theory of planned behavior used for data collection.The questionnaire was completed by the students twice, before and three weeks after the implementation of nutritional education. Data were analyze using descriptive statistics, Mann-Whitney, and Wilcoxon Signed Ranks. Result: The results of this study show nutrition education based on theory of planned behavior influence knowledge (p<0.001), attitude (p<0.001), subjective norms (p=0.002), perceived behavioral control (p<0.001),intention (p<0.001), but doesn’t influence limited fast food consumption (p=0.570). Conclusion: Nutritional education based on the theory of planned behavior influence knowledge, attitude, subjective norms, perceived behavioral control, and intention, but not effect to limited fast food consumption. So, nutrition education designed based on TPB effective to be implementation of health promotion.ABSTRAK Latarbelakang: Gencarnya promosi fast food  menimbulkan persepsi bahwa makanan cepat saji merupakan tren dikalangan remaja. Kebiasaan konsumsi makanan cepat saji yang mempunyai tinggi kalori namun rendah zat gizi menimbulkan masalah gizi lebih dan defisiensi zat gizi mikro pada remaja.Tujuan: Tujuan penelitian ini dilakukan untuk mengetahui pengaruh pendidikan gizi berbasis Theory of Planned Behavior terhadap perubahan pengetahuan, sikap, norma subyektif, perceived behavioral control, intensi, dan konsumsi membatasi fast food pada siswi di SMA Negeri 2 Sidoarjo.  Metode: Penelitian ini dilaksanakan dengan metode quasy experimental pada 32 siswi (16 siswi kelompok kontrol dan 16 siswi kelompok perlakuan) dipilih menggunakan simple random sampling. Pendidikan gizi berbasis TPB dilakukan selama 4 sesi yiatu sesi sikap, norma subyektif, PBC, dan intensi. Kuesioner penelitian yang digunakan untuk meneliti berbasis TPB. Penilaian dilakukan dua kali, yaitu sebelum dan 3 minggu setelah edukasi. Data dianalisis secara deskriptif, uji Mann Whitney dan Wilcoxon Signed Ranks.Hasil: Berdasarkan hasil penelitian bahwa pendidikan gizi berbasis theory of planned behavior mempengaruhi pengetahuan (p<0,001), sikap (p<0,001), norma subyektif (p<0,002),  perceived behavioral control (p<0,001), dan intensi (p<0,001) tetapi tidak mempengaruhi perilaku siswi untuk membatasi fast food (p=0,570).Kesimpulan: Pendidikan gizi berbasis TPB dapat mempengaruhi sikap, norma subyektif, PBC, dan intensi tetapi tidak merubah perilaku membatasi fast food. Dengan demikian maka diperlukan pendidikan gizi yang berkelanjutan agar dapat merubah suatu perilaku pembatasan fast food.

Introduction: Genetically Modified (GM) food is a point of debate in the world. There have been few relevant studies in Iran, so this study aimed to predict the consumption of genetically modified oil by the staff of health centers based on the planned behavior theory. Methods: In this cross-sectional study, 105 staff members of health care centers of Yazd in Iran completed a researcher-made questionnaire in 2012. The questionnaire validity and reliability were verified. The resulting data were analyzed via Pearson correlation coefficient and linear regression model. The data were analyzed using SPSS software and at the number below 0.05 regarded as significant. Results: Attitudes and subjective norms had the strongest positive, significant correlations with consuming genetically modified oil (r=0.619, r=0.526, p<0.01) respectively. Predictors of consuming intent for genetically modified oil showed that 43.2% of the variance of intention was determined by the attitude, subjective norms, and perceived behavioral control. Conclusion: Since the attitude was identified as the strongest predictor of consuming intention of genetically modified (GM) oil, studying the factors influencing the attitude toward GM food in different social levels of Iran is recommend. The results provide important evidence for supporting the use of this theory in predictions of food-related consumption behaviors, especially in the area of new food products.

To address the problem of malnutrition in poor rural areas of China, this study aims to examine the effects of social-psychological factors in food consumption of rural residents in poor counties of Southwest China. In addition, it investigates the role of perceived need and habit within the theory of planned behavior (TPB) in predicting food consumption. A survey with random sampling was conducted on rural residents (n = 424), and the theoretical frameworks of both the standard and extended TPB were applied for comparison purposes. Structural equation modeling was applied to test the relationships among constructs. Consumption of five food items was studied, respectively: meat, eggs, dairy, fish, and fruits. Results showed that incorporation of perceived need and habit substantially increased the explanatory power of the TPB, but these factors only had significant direct effects on intention rather than behavior. Perceived need and habit are stronger predictors of intention than any other TPB construct for consumption of all food items except for meat. We found indirect effects of the constructs in the extended TPB model on consumption to be different across food items. Practical implications to improve consumption of different food items were proposed accordingly.
