This study aimed to compare robust regression research by using M estimation and  S estimation on the factors that affect IR DHF.

This study utitlized observational research with a non-reactive research design using secondary data. The independent variable consisted of population density, healthy behavior, healthy living environment house, and precipitation in East Java in 2017. The dependent variable was incident rate of DHF in 2017. The population included 38 regencies in East Java, while the sample was 35 regencies/cities selected using simple random sampling.

The trend of the neonatal mortality rate in Indonesia has decreased from 15 (2017) to 13 deaths per 1,000 live births (2018), but this does not meet the Sustainable Development Goals (SDGs) target. Evidence-based health interventions are based on determinants that most influences neonatal mortality. The purpose of this study was to determine the most influential determinants of neonatal mortality in Indonesia. This research is an analytic observational study that uses the 2017 Indonesian Demographic and Health Survey (IDHS) data, with a cross-sectional design. This study’s population was the last baby of married women of childbearing age (15-49 years) and was recorded in the 2017 IDHS with a sample of 15,102 babies. The outcome variable in this study was neonatal mortality. The analysis was conducted in stages, namely univariate analysis, bivariate analysis using the chi-square statistical test (X2), and multivariate analysis using logistic regression. The results showed that 85.71% of deaths occurred in the early neonatal period. The most influential determinants of neonatal mortality were male sex (adj OR = 2.91: 95% CI 1.78-4.76), low birth weight (adj OR = 12.08: 95% CI 7.38-18.86) and parity status ≥ 4 (adj OR = 2.11: 95% CI 1.22-3.61). Public health interventions aimed at reducing neonatal mortality should be linked to newborn and maternal characteristics that significantly influence Indonesia's neonatal mortality. Therefore, health services must consider adequate postpartum neonatal care that is fully integrated with medical care. Moreover, further prevention of potential factors that cause low birth weight before conception should be implemented and further control of births would optimize the family planning program. Keywords: gender, low birth weight, parity status, determinant, neonatal mortality, Indonesia","PeriodicalId":33636,"journal":{"name":"The Indonesian Journal of Public Health","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49221722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A large number of women in the workforce and the unavailability of breastfeeding facilities are among the factors influencing the low coverage of exclusive breastfeeding in Indonesia. In addition, maternal knowledge is also a contributing factor for exclusive breastfeeding practices This study aims to analyze the relationship between the availability of lactation facilities and maternal knowledge with exclusive breastfeeding.

Nowadays, one of the consequences of the rapid development of the manufacturing industry in Indonesia is related to work productivity. Each person's work productivity is not the same, one of them depends on the availability of nutrients in the body. Lack of nutritional consumption for someone from standard needs will affect health conditions, activities, and work productivity. Nutritional substances in workers also affect fitness in addition to other factors such as age, health status, nutritional status, nutritional status, gender, and psychological conditions. Based on the description above, it is necessary to study the relationship between nutritional status and physical fitness of workers in manufacturing companies in Indonesia. The study was cross sectional on 120 workers from 6 manufacturing companies in Indonesia which was conducted using cluster sampling. Assessment of individual characteristics was conducted by direct interview. Assessment of nutritional intake uses the Food Frequency Questionnaire (FFQ) and the results were categorized as appropriate and inappropriate based on the 2019 nutritional adequacy figure for the Indonesian population. The fitness assessment (physical capacity) used a six-minute walking test by an occupational specialist and was converted to Meters and categorized with a cut off of 4.5 Mets to be sufficient or insufficient. About one third of manufacturing workers were centrally obese. Characteristics The dietary intake according to the recommendation were only about 10%, namely the appropriate carbohydrate intake 11.7% (Frequency 8.46 times (533.22 gr)), suitable fat 12.5% (Frequency 2.75 times (57.14 gr)), and suitable protein 10% (Frequency 6.55 times (101.77 gr)). The physical capacity of manufacturing workers in Indonesia was categorized as sufficient as much as 75.8% of their workload.
