The most widely used contraceptive method in Indonesia is hormonal contraception with injection types. Depo Medroxy Progesterone Acetate (DMPA) is a type of injection contraception that is widely used, ordinary people know it as a 3-month birth control injection. The 3-month injection contraception has advantages and disadvantages. One side effect of progesterone hormone content in the cardiovascular system can lead to the increased of bloodpressure. This study aims to determine the relationship between the duration of 3-month injection contraception usage and the incidence of hypertension in mothers of Dukuh Village, Bayat District, Klaten Regency. This study uses a descriptive correlational design with a cross sectional approach. Probability sampling was used as a sampling technique with a simple random sampling method with a total sample of 52 respondents. The statistical test used was kendall tau. The research results obtained p value 0.00 ( p value <0.05), so it can be concluded that there is a relationship between the duration of 3-month injection contraception usage and the incidence of hypertension in mothers of Dukuh Village, Bayat District, Klaten Regency.

Background: Adolescent obesity is a complex condition involving medical, psychology and cultural issue. Changing dietary practices and an increasingly sedentary lifestyle predispose to obesity related nutritional behavior. Obese adolescents have impact on psychological problem, including stress, social discrimination, reduced self-esteem, self-dissatisfaction and resulting in lower quality of life.Objectives: This study describes nutritional behavior and psychosocial factors in overweight and obese adolescent. Methods: A qualitative study was conducted in the Public Senior High School (SMA 2) on July to August 2015, in Semarang City. In-depth-interview and Focus Group Discussion (FGD) were carried out with 20 of obese adolescent aged 15 to 17 years, 2 parents, 2 teacher and 2 friends. Thematic analysis is used to identify themes in a data.Results: The majority participants considered the timing of obese are when they reach puberty. The pattern of food habits of obese adolescents become unhealthy. Obese adolescents also feel the bullying or ridicule from friends, so that they psychologically disturbing. Environmental factors play a role in the incidence of obese adolescents, namely lack of control by parents. The parents say that obese adolescents are still in a reasonable level because the adolescent has not shown any serious health problems, but a sense of fear still owned by the parents of obese adolescents.Conclusion: The findings show obesity in adolescent has not been considered as health problem. Unhealthy diet, bullying, poor motivation and lack of peer supports are contributing factors in obese adolescent.

The study aimed to evaluate the role of neck circumference for predicting insulin resistance in adolescent compared with waist circumference and waist hip ratio. A cross sectional study was conducted by measuring anthropometric parameters (neck circumference, waist circumference, hip circumference) and biochemical parameter (fasting plasma glucose, fasting insulin, and HOMA-IR) involving 80 late adolescents. Statistical analysis used in this study were Pearson and Spearman correlation, multivariate linear regression. Neck circumference positively correlated with fasting insulin and HOMA-IR in both gender, while neck circumference only positively correlated with fasting plasma glucose in men. In addition, multivariate linier regression showed that a higher regression coefficient of waist circumference associated with a higher risk of insulin resistance (fasting insulin (β=0.11; p<0.05), HOMA-IR (β=0.05; p<0.05)) compared to neck circumference and waist hip ratio. Neck circumference, waist circumference, and waist hip ratio is an anthropometry indicators that could be used to predict insulin resistance. However, waist circumference is better than neck circumference and waist-hip ratio for predicting insulin resistance in adolescent.

In the hydrocarbon material, there is a lot of conceptual, factual, and procedural knowledge that must be managed by students. One component of learning success is determined by the quality of teaching materials provided to students. Therefore, teaching materials are used to comply with the requirement of students in understanding hydrocarbon materials in the form of a hydrocarbon e-module based on guided discovery learning that has been valid and practical so that it can improve student learning outcomes. The purpose of this study was to determine the effectivity of the e-module used on student learning outcomes at SMAN 13 Padang. This research is quasi-experimental research (Quast Experiment Research) using a nonequivalent control group design. The population is class XI MIPA SMAN 13 Padang in the academic year 2022/2023. The sample selection was done by random sampling technique, by choosing class XI MIPA 2 as the experimental class and class XI MIPA 4 as the control class. The instrument used in this study was a multiple-choice test consisting of 25 questions and 5 valid, reliable, and discriminatory answer choices, and a difficulty index with good criteria. The effectivity level of the e-module was analyzed from the n-gain test value. The results obtained n-gain in the experimental class 0.6 while in the control class 0.55 with a medium category. So that the hydrocarbon e-module based on guided discovery learning is effectively used to improve student learning outcomes.

Background: Obesity is one of the risk factors for insulin resistance. Insulin resistance plays an important role in the pathogenesis of cardiovascular disease. Wrist circumference has the potential for predicting obesity and insulin resistance.Objectives:. To evaluate the sensitivity and specificity of wrist circumference against obesity and insulin resistance in late adolescents.Methods: The design of this study is a crossectional study with a sample of 85 students at Diponegoro University Semarang. Data collected consisted of anthropometric measurements (body weight, height, wrist circumference, neck circumference, waist circumference and pelvic girth) and blood vein sampling (fasting blood glucose and fasting insulin). Statistical analyses used in this study were Pearson or R Spearman correlation test.Results: Wrist circumference was positively correlated with all biochemical parameters and anthropometric measurements except the waist hip ratio. Wrist circumference correlates positively and significantly with fasting insulin and HOMA-IR in male adolescents. The results of the ROC curve analysis showed that the AUC value of wrist circumference in male adolescents had better performance in predicting obesity (88% (95% CI, 76% - 100%)) than insulin resistance (81% (95% CI, 51% -100%)).Conclusion: Wrist circumference is one of the anthropometric measurements that can be used for predicting obesity and insulin resistance in late adolescents.
