This is the 3rd assignment for public health, each assignment piggy backs off of the previous. I recently posted this assignment and got a bad grade from a previous tutor. Please do not do assignment if you do not understand the requirements. Attached will be any pertinent information(First two assignments) and/or rubric. **PLEASE look at the attachment named PBH203 Paper 3 to see the previous submission that was done completely incorrectly and to see what you should not do.
*Using the literature you have found and some additional if needed, present and comment about each of the letter topics described below. I am not looking for definitions of those concepts, I am looking for a correct interpretation in the context of your literature. For example, “sex was an effect modifier in the association between domestic violence and poor health. Women’s health declined when living in a household with domestic violence while men’s health stayed the same.” In that way, I know you learned how to use the concept of domestic violence.
Questions are always welcome.
