Gender theory is the study of what is understood as masculine and/or feminine and/or queer behavior in any given context, community, society, or field of study (including, but not limited to, literature, history, sociology, education, applied linguistics, religion, health sciences, philosophy, cultural studies). The term sex refers to categories of the biologically observable human body, female and male or intersex (i.e., nature), while the term gender refers to the categories of social expectations, roles, and behaviors, feminine and masculine.

      Global health and public health are indistinguishable. Both view health in terms of physical, mental, and social wellbeing, rather than merely the absence of disease. Both emphasise population-level policies, as well as individual approaches to health promotion.

The scope of a public health specialist is limited to a particular community. Global health goes beyond those limits, and even transcends political boundaries. —So you are a specialist in public health on an international level.

The 10 global health issues:

·         Physical Activity and Nutrition. ...

·         Overweight and Obesity. ...

·         Tobacco. ...

·         Substance Abuse. ...

·         HIV/AIDS. ...

·         Mental Health. ...

·         Injury and Violence. ...

·         Environmental Quality etc.

Global health emphasizes prevention at the population level and is vital to helping maintain global security. Global health is important because it aims to improve worldwide health, access to health care services and the quality of health care for all.
