Background: Anemia is a globally public health problem, including in Indonesia (22.2%) and it has negative health impacts. Adolescent girls have high risk of anemia. Previous studies reported that adolescent girls at islamic boarding school had low food intake and poor knowledge about nutrition in preventing anemia. Objectives: To assess the prevalence of anemia and to analyze association between knowledge, nutritional status, and dietary habits and anemia in adolescent girls. Materials and Methods: A cross-sectional study was conducted in November 2020 among adolescent girls at islamic boarding school in Semarang. A total of 162 respondents were selected by cluster sampling. Anemia was determined by measuring the hemoglobin level in the blood by Cyanmethemoglobin method. Knowledge and dietary habits were collected through questionnaires. Nutritional status was assessed by measuring weight and height, then classified by body mass index for age using WHO Anthro. Bivariate and multivariate logistic analysis were used to test hypothesis and it was significant if p<0.05. Results: The prevalence of anemia was found to be 17.3%. In the bivariate analysis, overweight was more likely to have anemia (p=0.044). There was no association between father’s education, mother’s education, knowledge, frequency of staple food, breakfast habits, consumption of animal side dishes, consumption of vegetable side dishes, consumption of sweet tea and anemia. Mulitvariate model showed that overweight (OR=3.658; 95%CI=1.224-10.932; p=0.020) and good knowledge (OR=3.652; 95%CI=1.221-10.922; p=0.020) were significant associated with the anemia.Conclusion: Nutritional status and knowledge were significantly associated with anemia among adolescent girls.

Background: Obesity is one of global epidemic health problems and its prevalence is higher among women. Obesity can cause low grade chronic inflammation mechanism in adipose tissue, which is characterized by the increase of proinflammatory cytokines and adipokines. Neutrophil lymphocyte ratio (NLR) is a simple inflammatory marker which can be reliable in evaluating the inflammatory status occurring in obese women. Waist to height ratio (WHtR) and waist to hip ratio (WHR) are anthropometric measurements, have been reported to be associated with obesity and risk of metabolic syndrome.Objective: This study aimed to determine the correlation of WHtR and WHR with NLR in population of obese women.Materials and Methods: This was a cross sectional study enrolling 80 obese women with Body mass index (BMI) > 27 aged 30 - 50 years in National Diponegoro Hospital Semarang, Indonesia. WHtR was determined by dividing waist circumference by height and WHR was determined by dividing waist circumference by hip circumference. NLR was examined manually from automatic hematology analyzer by dividing absolute neutrophil count (ANC) and absolute lymphocyte count (ALC). Spearman correlation test was performed, p<0.05 was considered as statistically significant.Results: There was significant weak positive correlation between WHtR and NLR in obese women (p = 0,046; r = 0,224). There was no significant correlation between WHR and NLR in obese women (p = 0,961; r = 0,006).Conclusion: The present study showed that WHtR is one of better anthropometric measurement because it is associate with NLR as a simple marker of inflammation in obese women.

Background: Asthma is a chronic respiratory disease most often found in children and has the highest prevalence in developing countries. House dust mites are the second most common trigger of asthma whose habitat is influenced by the criteria for a healthy.Objective: Understanding the correlation between sleep density and asthma status in pediatric patients and criteria for a healthy house.Methods: This study was an analytical observational method with a cross sectional study design that took place from June to October 2020. It involved 25 respondents of children with asthma patients aged 3-11 years. There is a confounding variable, namely the criterion score for a healthy house. Dust samples were collected in the bedroom of the respondent diagnosed with bronchial asthma. The identification process using the floating method was carried out at the Parasitology Laboratory, Faculty of Medicine, Diponegoro University, Semarang Indonesia. Respondent data were analyzed using statistical software programs. Non-parametric test with lambda correlation test.Results: The mean of house dust mite’s density in the respondent's house was 3.68 ± 2.32. House dust mite’s density was associated with the criteria for a healthy house (p <0.05), but house dust mite density was not related to the asthma status of pediatric patients (p> 0.05).Conclusion: There is no correlation between pediatric asthma status and house dust mite density.
