Differences in Microplastic Content in Commercial Salt and Salt at the Semiringkai Coastal Local Center in Kupang City and Kupang Regency.

Background: Plastic waste that ends up in the ocean can undergo a degradation process into small plastic particles measuring 5 mm called microplastics. The presence of microplastics in the sea can contaminate marine products such as sea salt. Microplastics in the salt consumed by humans can cause adverse health effects. This study aims to determine the difference in the content of microplastics in commercial salt and local salt from the semiringkai coast in Kupang City and Kupang Regency. Material and Methods: This research is an observational analytical study with a comparative analysis design. The method used is laboratory observation using a microscope. This study used 10 salt samples which were divided into 2 groups, namely the commercial salt group and the local salt group, each consisting of 5 salt samples. Samples were taken using non-probability sampling method with purposive sampling technique. Data were analyzed univariately and bivariately using the independent T-comparison test. Results: The results of the analysis test in this study were P = 0.065 (P > 0.05). Conclusion: There is a content of microplastic in commercial salt and local center salt of the semiringkai coast in Kupang City and Kupang Regency with an average that is not significantly different.

The contribution of nutrition and quality of sleep and happiness in under-five-year-old children.

Introduction: This study aimed to evaluate the relation between happiness perception of children and quality of sleep, appetite, dietary intake and nutritional status. Materials and Methods: A cross-sectional study evaluating happiness, quality of sleep, appetite, dietary intake and nutritional status in 296 Indonesian children less than five-years of age. Results: There was no significant difference on perceived happiness between urban and rural areas (P = 0.087). The proportion of children that are perceived as happy by mothers (55.1%) is significantly higher (p < 0.001) as perceived as happy by fathers (50.7%). A significant lower dietary energy intake with a higher percentage of dietary protein to total energy intake was observed among those children that are perceived as happy. However, after adjusted to body weight, there was no significant difference in the amount of protein intake between those perceived as happy and unhappy. Amongst the nutritional status indicators, this study found a significantly higher Height-for-Age Z score among the children that perceived as happy. Conclusion: Height-for-age Z score and dietary protein intake in children aged 2-5 years are associated with quality of sleep and appetite, and may therefore affect children's happiness. Not only parental care but also appropriate nutrient intakes influence the child's happiness.

Seasonal variation in the nutritional status of children aged 6 to 60 months in a resettlement village in West Timor.

Childhood malnutrition remains a public health issue in Indonesia with a national prevalence of wasting of 13% and stunting of 36%. In rural areas nutritional status depends on local agriculture and may fluctuate in relation to harvest time. The aim of this study was to characterise seasonal variations in nutritional status in two resettlement villages in the Oesao district, Nusa Tenggara Timur. A cross sectional study was conducted in a convenience sample of children after the wet season (March). Children aged 6 to 60 months were assessed for nutritional status using anthropometric and biochemical measures. A subset of these children was re-assessed for anthropometry after the dry season (November). Weight-for-height z scores improved significantly from mean±SD of -1.7± 0.9 in March to -1.3±0.9 in November (p<0.001). There was no significant change in height between seasons. Prevalence of wasting, (weight-for-height z score <-2), was 42% in March and 19% in November (p<0.001). However, stunting rates increased significantly from 42% in March to 45% in November (p<0.001). Thirty six per cent of children were anaemic (Hb level <11 mg/100 mL), 68% were vitamin A deficient (plasma vitamin A level <0.8 µmol/L) and 50% were zinc deficient (plasma zinc <9.94 µmol/L). All children except one were positive for intestinal parasites. These data indicate seasonal changes in anthropometry with inconsistent effects depending on the anthropometric index measured. Wasting and stunting were higher than the national average, alongside high rates of anaemia, zinc and vitamin A deficiencies.
