Judul: Risk Facktor Stunting In Children Aged 18-24 Month
Abstrak: Stunting is a condition that describes stunted growth as a result of long-term malnutrition. Based on the World Bank (2018), as many as 22.2% of children under five in the world experience stunting. Basic Health Research 2018 data shows the prevalence of stunting in Indonesia is 30.8%. The results of the Indonesian Nutritional Status Study how the prevalence of stunting in West Java is 24.5%. Bogor is one of the areas in West Java where stunting or stunting is still found with a prevalence of 16.9%. Research related to stunting risk factors has been widely carried out in several regions in Indonesia, but research related to stunting risk factors using Child Growth Cohort Study data has never been carried out. Therefore, the general objective of this study is to analyze the risk factors for stunting in children aged 18-24 months. The specific objectives are 1) To examine linear growth disorders (stunting) in children aged 18-24 months; 2) To analyze non-consumption risk factors, including: sociodemographic, economic and health characteristics with stunting children aged 18-24 month; 3) To analyze dietary diversity with stunting children aged 18-24 months; 4) Analyzing the factors that influence stunting children aged 18-24 months. The design of this research is nested case-control, using secondary data from “Cohort Study of Child Development in 2012-2017” which was carried out by the Agency for Research and Development of Public Health Careers, Agency for Health Research and Development, Ministry of Health, Republic of Indonesia. The data analyzed in this study were sociodemographic, economic and health characteristics in the form of gender, birth weight, birth length, mother's education, mother's knowledge, family income, history of breastfeeding, mother's height, eating patterns, health care patterns, history of breastfeeding. infectious diseases in the form of diarrhea and acute respiratory infections (ARI), as well as the diversity of food consumption. Data on sex, birth weight, birth length, maternal education and maternal height were taken at one measurement point at baseline. Exclusive breastfeeding data was taken at one measurement point when the child was 6 months. Data on history of infectious diseases (diarrhea and ARI) were seen for a period of 17 months. Nutritional status was measured at the age range of 18-24 months. Data on maternal parenting patterns (eating and health care) were taken at one measurement point at 17 months. The consumption data in this study were observed at four measurement points, namely 6,9,12 and 18 months of age. However, in this study, the researchers simplified the measurement of consumption data into two measurement points, namely measurement one in the form of the average consumption of children aged 6 and 9 months, and measurement two the average consumption of children aged 12 and 18 months. The basis for consideration is grouping into two measurement points because based on the results of the analysis, it was found that there was no difference in the consumption of children aged 6 and 9 months, as well as children aged 12 and 18 months. Consumption diversity was measured using the Minimum Dietary Diversity (MDD) instrument with 8 food groups. Data were analyzed using

Judul: Risk Factors of Stunting Among School-aged Children
Abstrak: Based on the results of Indonesian Basic Health Research in 2010, the national prevalence of stunting among school aged children (6-12 years old) was 35.6%. Stunting is a major public-health problem in low and middle-income countries because of its association with increased risk of mortality during childhood. Stunting also leads to significant physical and functional deficits among survivors (The Lancet 2008). Stunting affects the development of cognitive processes during school-aged period (Kar et al. 2008). Several studies have shown that during school-aged period, children was less experienced catchup growth or remain stable even experienced stunting (Friedman et al. 2005). Health Research and Development Agency of the Indonesian Ministry of Health has conducted a Basic Health Research at national scale in 2010 that could potentially be analyzed to determine the risk factors for stunting in school-aged children. Therefore, the objective of this study was to analyze risk factors of stunting among school-aged children. Specifically, objective of this study as follows: (1) identify the characteristics of the children and families of stunted and normal children, (2) identify health and environmental sanitation in stunted and normal children, (3) identifying the incidence of infectious diseases (malaria) in stunted and normal children, (4) analyzing the quantity and quality of food consumption in stunted and normal children and (5) analyze factors that influence the incidence of stunting in the children. This study used secondary data from Basic Health Research by Health Research and Development Agency of the Indonesian Ministry of Health in 2010 with a cross-sectional study design. The data analyzed in this study were from eight Provinces which selected according category of prevalence of stunting (WHO 1997), were very high (≥ 40%) in East Nusa Tenggara and North Sumatra, high (30-39%) in West Nusa Tenggara and West Java, moderate (20-29%) in Bangka Belitung, Jakarta and Yogyakarta, and low (<20%) in Bali. Processing and data analysis was conducted in June-October 2013. Subjects of this research are boys and girls aged 6-12 years from eight provinces. Number of subjects contained in the electronic files was 11335 children. After a cleaning process, the number of children analyzed was 8710. Analysis data used Microsoft Excel 2007 and SPSS for Windows version 17.0. The t test and oneway ANOVA was used to determine mean difference of variable with data continues and mean HAZ. Chisquare test was used to determine relationship between independent variable with stunting. Multivariate analyzes were performed using logistic regression with Backward Wald method with statistical significance criteria of p<0.05, and the value of the confidence interval (CI) of 95%. Prevalence of stunting in eight provinces was 28.11 % and 11.38% were categorized as severe stunting. Stunted children were higher in older children (10- 12 years), male, mother with short stature (<145 cm), parents with low education levels (≤ primary school), father who smoking, mother with a low BMI and father 6 with normal BMI, children with ≥ 8 family member, low household expenditure (quintiles 1 and 2), and living in rural areas. There were significant relationship between children with older age (10-12 years), male children, low maternal height (<145
