chapter 1 Flashcards
thinking about individual and population health
Level of analysis
individual level ,population level
ecological fallacy
relevant health factors
age ,sex genetic inheritance
collective variable,
properties measure which describe an entire group ,system or population(explains why income distribution not an individual analysis)
Aggregated individual measure
combines individuals data point ex; average income in a city ,summerizes individual -level data to make inference about a population or context.
proximate factors
two factors that are close to each other ‘variables that are near in time or proximity to the event ;are keys they re the prime exterminates of a cause.
Host charactherisic 1 ;Age
-not a powerful precise predictor because of substantial variation why 1.there is variation in all ages when it comes to health 2. our older population are becoming healthier 3.health depends on the type of life you lived 4.health at different ages differs based on different nations
host characteristic 2; sex
-sex definiton ; the biological and physiological aspects of males and females.
-very weak
-biological sex is a spectrum
-All people are have blend of female and male hormones
‘sex itslef is not a biological mechanism
gender
-the social expectation placed on a person and the roles the persons adopt
-many health related difference between men and women are more gender than sex related
Host characteristic 3 ;Genetics
-
DNA
-discover by Watson and Crick 1950
-Four based pairs
-codon who codes for a protein
genomic is not likely the answer to health is because there so many variation and contradicting studies
-still very few unambitious genetic disease
genetic testing issues
-
-
-
gene-environment
where a particular genetic variants has an effects only when exposed to an environmental factors or if and enviromental exposure has an effect only when it interact with specific genetic variant
