Vergleich des Wasserhaushaltes und der Elektrolytbilanz bei Kaffee- und Nicht-Kaffeetrinker/innen

Ziel der Arbeit: Mit dieser Arbeit soll mit einigen Mythen um eines unserer beliebtesten Getränke aufgeräumt werden. Ist ein Unterschied im Wasserhaushalt zwischen Kaffeetrinker/innen und Nicht-Kaffeetrinker/innen gegeben? Gibt es in diesen beiden Gruppen einen Unterschied in der Elektrolytausscheidung? Methoden: 11 Kaffeetrinker/innen und 10 Nicht-Kaffeetrinker/innen erklärten sich dazu bereit an der Studie teilzunehmen. Mittels Wiegeprotokoll wurde die Wasser- und Elektrolytaufnahme protokolliert. Durch Sammeln des 24h Urins und anschließenden Laboruntersuchungen auf Volumen, Natrium-, Chlorid-, Kalium- und Calcium-Ausscheidung wurden die nötigen Daten erhoben. Ebenso wurde der Coffeingehalt eines haushaltsüblichen Filterkaffees bestimmt, um Ergebnisse anderer Studien besser vergleichen zu können. Resultate: Es gab keine signifikanten Unterschiede in der Wasseraufnahme beziehungsweise Wasserausscheidung zwischen Kaffeetrinker/innen und Nicht-Kaffeetrinker/innen. Ebenso zeigte die Verteilung der Flüssigkeiten im Körper keine Unterschiede. Die Elektrolytausscheidung war nicht signifikant abweichend bei den beiden Gruppen. Conclusio: Kaffee kann bei regelmäßigem Konsum weder als Flüssigkeitsräuber angesehen werden, noch entzieht er dem Körper Elektrolyte.The aim of the study was to clear up with some myths around one of our most popular drinks. Is there a difference concerning the water household and electrolyte excretion between coffee consumers and non-coffee consumers? Methods: 11 coffee drinkers and 10 non-coffee drinkers took part in the study. The water and electrolyte ingestion were recorded with the aid of weight logs. The necessary data were raised by collecting the 24h urine, which was tested for volume, sodium elimination, chloride elimination, potassium elimination and calcium elimination. Additionally the content of caffeine from a customary filter coffee was measured in order to be able to compare results of other studies. Results: There were no significant differences in the water ingestion or water elimination between coffee consumers and non-coffee consumers. No differences were shown regarding to the distribution of the liquids in the body. The electrolyte elimination was not significant different within both groups. Conclusion: In general, there is no increased elimination at a regular level of regularly consumption of coffee. Coffee does not cause dehydration and does not take away electrolytes

Factors Associated with (Exclusive) Breastfeeding Duration—Results of the SUKIE-Study

The WHO European Region has the lowest exclusive breastfeeding (EBF) rates at 6 months in the world. In Austria, 55.5% of infants are EBF at the age of one week, although breastfeeding initiation is 97.5%. The study was conducted in 2019/2020 and considered 1214 mothers of legal age, who received four online questionnaires during their child’s first year of life. The influence of different variables on total/exclusive breastfeeding duration were analysed by using a Cox model (Extension of the Cox Proportional Hazards Model) with time-dependent covariates. Multivariate analyses showed a significant influence of maternal BMI, lifestyle factors, such as smoking, and breastfeeding support on total breastfeeding duration. Remarkable differences in the median duration of any breastfeeding were found for breastfeeding support, where mothers breastfed twice as long. Support came primarily from hospital staff, the midwife and the partner. A higher monthly household net income, delivery in a baby-friendly certified hospital (BFH) and breastfeeding support were associated with a longer EBF duration. Obese mothers started feeding infant formula earlier and had a higher risk of early weaning. The results offer valuable insights into the importance of breastfeeding-friendly structures such as BFHs, a focus on breastfeeding aftercare and support of the mother to promote and protect breastfeeding
