Background : Premenstrual syndrome generally known as the interruption the existing hormonal changing during menstrual cycle that will disturb the emotional and physical comfortable. It works on women during the reproductive age. The syndromes are denoted by the amount of signs and symptoms that occurred during fase luteal at the menstruation cycle. Psycho-emotional problems are more than common premenstrual complaint, although physical anxiety more often occurred during menstruation period. Factors of micronutrient intake (calcium, magnesium) greatly affect mood and behavior during premenstrual syndrome.Objective : The study was to identify relationship between nutritional status, micronutrient intake (calcium, magnesium), and premenstrual syndrome among female adolescence.Method : The study was observational or non-experimental which used cross sectional design. The populations were female adolescence of Sejahtera Senior High School at Surabaya. Samples were taken using total sampling technique because the subject had been determined to those aged 16–18 years. As many as 97 people fulfilled inclusion criteria. Data processing and analysis used univariable, bivariable, and multivariable techniques. Statistical test used logistic regression. Result : The result of the study showed that there was no significant relationship between good nutritional status and occurence of premenstrual syndrome (p = 0.086; OR = 2.278; 95% CI = 0.980-5.295), between calcium intake and premenstrual syndrome (p = 0.032; OR = 2.910; 95% CI = 1.176-7.200), between magnesium intake and premenstrual syndrome (p = 0.012; OR = 3.319; 95% CI = 1.369-8.043). There was significant relationship between calcium and magnesium intake and premenstrual syndrome. Conclusion : The result of multivariable analysis showed that nutritional status, intake of calcium and magnesium had significant relationship with premenstrual syndrome.

Background:  Adolescents pay such close attention to their physical shape and frequently construct their own body image. Low knowledge of nutrients will have an impact on attitudes and behavior related to nutritional status in adolescents. Nutrition education can also help youth gain adolescents' knowledge. Peers are believed to be very influential as educators, so, peer nutritional education in adolescents will be felt positively and have a very significant impact on nutritional status. Aims: This study aims to determine the effect of nutrition education conducted by peers, nutrition, and a combination on the nutritional status of adolescents. Methods and Material: This research used is a quasi-experimental design using a pretest-posttest control group design.The sample consisted of 120 students with an age range of 15–18 years, selected by random sampling. Nutrition education is provided by means of lectures and discussions by peers, nutritionists, or a combination of the two for 1 meeting a week. Statistical analysis used: This study will use the paired t test. Results: The findings revealed that nutrition education delivered by peers had a p value of 0.033 and nutrition education delivered by nutritionists had a p value of 0.003, but there was no significant effect on adolescent nutritional status when nutrition education was delivered in combination with a p value of 0.317. Nutrition education provided by peers is very useful for improving the nutritional status of adolescents. Conclusions: Nutritional education provided by peers is proven to be able to have a positive impact on adolescents because peers are the axis of youth association, so that what is shared and learned by peers will be more easily accepted.

Consumption of folic acid intake, B12 and the pattern of menstruation are factors causing the occurrence of anemia, vitamin B12 and folic deficiency often occurs in young women. Deficiency of one or several nutrients such as iron, vitamin B12, folic acid, and vitamin C, which is necessary for the formation of nutrients can cause nutritional anemia. The purpose of study was to know the intake of folic acid intake, Vitamin B12 and menstruation pattern with the incidence of Anemia in young women in Surabaya Junior High School. Research method was cross sectional approach. The study population of all female students who have menstruated in Surabaya Junior High School was taken by simple random sampling. The research instrument was questionnaire by 24-hour Food Recall and FFQ complement data that could not be obtained through 24-hour memory, menstrual pattern questionnaires and hemoglobin results by measuring hemoglobin (HB) by cyanmethemoglobin method. Data analysis was using logistic regression test. The result was 19.007 (p = 0.000; OR = 31.000-; 95 percent CI = 4.002- 240.150), this means there was a significant association between vitamin B12 intake and the incidence of anemia (p < 0.05), and the menstruation pattern was 10.340 (p = 0.001; OR = 4.846-; 95 percent CI = 1.897- 12.379), this means there was a significant relationship between the pattern of menstruation and the incidence of anemia (p < 0.05). Vitamin B12 intake and menstruation pattern significantly influenced the incidence of anemia (P =
