Improving Hemoglobin Level with Increasing Copper, Cobalamin, and Iron Intake of Pregnant Women

/in /by

Over the past five years, there has been a dramatic increase in anemia problems among pregnant women in Indonesia. Almost half (48.9%) of pregnant women in Indonesia have anemia. Further research is needed to explore the role of additional nutritional deficiencies that cause anemia in Indonesia, apart from iron deficiency. The aim of this research was to determine the characteristics and nutrient intakes affecting pregnant women’s hemoglobin levels. A cross-sectional study was carried out from May to October 2019 on 60 pregnant women at Public Health Center Kebon Jeruk, Jakarta. The independent variables were pregnant women’s characteristics, intake of energy, protein, folate, vitamin B6, B12 (cobalamin), C, E, iron, copper, and calcium. The dependent variable was hemoglobin level. Multiple regression using dummy variables was used for multivariate analysis. The average age is 28.3+5.5 years old, with no mothers being of risky age. The average hemoglobin (Hb) level is 11.5+1.4 g/dL. The majority of women are in their third trimester (42%). The variables that significantly affect hemoglobin levels are the intake of iron, vitamin B12, and copper. Increasing the intake of iron, vitamin B12, and copper effectively improves hemoglobin levels among pregnant women. It is recommended to provide iron tablets in multi-nutrient form, and further research is needed for its effectiveness.

Features of Geological Structure and Mineragenic Specialization of Sheikhdzheyli-Zengiboba of the Sultan-Uvais Ridge Area

/in /by

The productive mineralization of the Sheikhdzheili-Zengiboba area is associated with metamorphogenic transformations of the rocks of the Urusai, Karauzyak, Kuyanchik, Sheikhdzheili suites, metamorphosed under conditions of green schist facies. The mineralized zones of the site are confined to narrow faults in the tectonic zones of the northeast and northwest directions. The main form of manifestation of gold-bearing mineralization is small steeply dipping veins, lenses, nests, non-extended systems of conformal and secant quartz veinlets containing dissemination of pyrite, arsenopyrite, chalcopyrite and pyrrhotite, which are represented by gold-arsenopyrite-pyrite, gold-arsenopyrite-chalcopyrite-pyrite natural type of ores.
