An introduction and examples of how to use the Chi square test. The test is used when analyzing assocation between two categorical variables and when comparing proportions. The idea behind the test is to compare the observed frequencies with the expected frequencies, if the two variables are unrelated.

What determines our health? Why does life expectancy differ so much from country to country, or even from one group to another in the same country? Well, there is no easy answer to these questions. There are many factors that play a part in determining the well-being of the population, or even of an individual. In global health, we call these factors determinants of health. Determinants of health interact with each other, and influence our health status is in numerous ways, in turn influencing our well-being, morbidity, mortality, and life expectancy. As you already know, the first and most important health determinant is income. Income of an individual or a household, but also income of the country a person lives in. Other important health determinants are education, access to water, diet, environment and many more. In this presentation we will look closer at how health determinants determine an individual’s health, and how different health determinants interact with each other.

No matter what your area of interest is, you need to know how to evaluate your subject, how to measure it. Global health is measured using something we call health indicators. To understand how a population in a country, or in a region, or even a part of a city is doing, you need to know its health indicators. How long do people live in this country? How many children die before they reach their fifth birthday in this city? What is the weight of children and adults in the northern part of the country? How many women die in childbirth in the country? Once you have looked at these numbers and compared them with other populations, you can make sense of the health situation of a population. In this lecture you will some basic health indicators, and also how the data is collected.

This presentation provides an introduction to diarrheal diseases caused by bacteria, viruses, parasites and other disease causing agents or pathogens. Furthermore, we’ll look at the range of syndromes associated with diarrhea and uncover two significant pathogens: rotavirus and vibrio cholera. Finally, we’ll delve into methods for managing diarrheal diseases and the significance of sanitation in preventing diarrheal diseases.

You must know the basic facts about the world population in order to grasp global health. You
need to know where people live in this world, how the world population is changing based on
the number of babies born per woman, on average, in the world as a whole and in the
different regions. And finally, you must learn how, why, and when the fast population growth in the world will
come to an end during this century. Please look at this video with five video clips where this is explained. And if something is surprising to you, please look twice.

Open Code is a tool for coding and categorizing qualitative data. Open Code 4.0 is a tool to help you index and sort big materials, so it can be searched and re-arranged for further analysis. Open Code was developed to follow the first steps of Grounded Theory but it is now possible to use it for all qualitative methods and it is prepared for Grounded Theory and Qualitative Content analysis. It is useful for sorting and classifying any kind of qualitative information. The software is developed to run on Windows. To run it on a Mac, you have to run a virtual machine or other systems to run pc-software on a mac computer.

This is an introduction to the fascinated multidisciplinary world of water, sanitation, and hygiene (WASH). An area relevant due to the 1,5 million people annually dying of WASH-related disease, but also highly relevant during any emergency, whether it is a cholera outbreak in the slums of Dhaka Bangladesh, drought and water shortage in Kenya or hygiene-related virus outbreaks anywhere on the globe. The course ties theories of engineering, anthropology, public health, epidemiology, microbiology, disaster management, etc. with practical exercises to provide the student with the multifaceted background knowledge needed to be able to respond in an emergency actively. The course Water and sanitation in Emergencies started as a response to the Tsunami in 2004 and is now an independent elective course under the world-renowned Master of Disaster Management program, http://www.mdma.ku.dk, at University of Copenhagen.
