The Effects of Green Beans and Soybean Juice on Haemoglobin (Hb) among Female Adolescents Aged 12-14 Years .

Introduction: Green beans (Vigna radiata) and soybeans are food sources that contain complete nutrition and micro-nutrients needed by adolescents. A female adolescent with menstruation may experience low haemoglobin. Thus, the purpose of this study was to analyse the effect of green bean and soybean juice on haemoglobin (Hb) among female adolescents aged 12-14 years. Methods: It was a quasi-experimental study design. A total of 60 female adolescents were recruited using the purposive sampling technique and divided into two groups. Each group was given green beans and soybeans juice. The length of interventions in each group was fourteen days. Then, we observed the Hb level before and after the intervention. Independent t-test and paired t-test were used for data analysis. Result: We found an increase in Hb level after giving green beans juice (11.82 gr/dL) and soybeans juice (11.95%). Data analysis showed a significant difference in each group before and after intervention (<0.001). Conclusion: Giving green beans and soybeans juice can be a complementary therapy besides drug therapy to increase Hb levels among female adolescents. Sources of intervention that are cheap and easily available can be a solution to increase Hb levels among female adolescents. [ABSTRACT FROM AUTHOR]
