This research is experiment research with random design toward subject. The population in this research is all of student at class of VIII SMPN 3 Lengayang of year 2013/2014. Technique of sampling is done by random sampling, furthermore it is chosen VIII.3 class as experiment class and VIII.4 class as control class. Instrument of this research is quiz and final test that is formed valid and reliable test in 0,83. Based the data analysis is knew that both of classes is normal distribution and homogeny in real taraf . Hyphotesis test result is got p-value  which is more little than , so hyphotesis is accept.

Data were analyzed by calculating the relative riskResults: 66,7% had a protein energy malnutrition, 51,9% had less weight gain during pregnancy, and 59,3% are anemic. The mean intake of energy, protein, folic acid, iron, zinc, vitamin A and C are in not enough categories. The relative risk test showed that less weight gain during pregnancy (RR= 3,71;95% CI 1,34-10,25, low energy intake (RR =6.03; 95% CI 5,68-898,64), low protein (RR= 13,00;95% CI 1,97-85,45), low folic acid (RR = 13,00;95% CI 1,97-85,45), low iron (RR= 4,00;95% CI 1,71-9,34) at risk of having low birth weight.
