14.1 Health psyhology and its applications Flashcards
most deaths are now related to ..
peoples behaviour
smoking is a learned social behaviour
- ppl are more likely to smoke if members of their family also smoke
- or if they belong to a culture or social group in which smoking is very common
- media depictions of smoking are not helping
study on smoking
- a study of adolescents revealed a positive correlation between whether they had tried smoking and their exposure to movies with favourable depictions of smoking
- in another study, even adolescents who hadn’t smoked before were more likely to report smoking as an aspect of their own Identity if they responded positively to a cigarette-smoking movie character
- from 1990 to 2007, there was an association between rates of smoking in movies and rates of smoking among adolescents
health psychologists have been working against these media influences
in the 1990’s, warning labels didn’t seem to have an effect; they were too easy to ignore
-more recently, text warnings with graphic images seem to work better. (40% of smokers identify the warnings on cigarette packages as one of their motives for quitting)
health psychology, eating, and exercise
our culture seems to value overeating and it doesn’t exactly support regular physical activity
Body mass index (BMI)
BMI=weight in KG/(Height in meters)^2
healthy BMI=18.5-24.9
underweight BMI=30.0
about 25% of Canadians fall into the obese range of BMI
increase in obesity is associated with a number of health risks
Twin, adoption, and family studies reveal that the heritability of of body size is between ___ and ____
.5 and .9
set point
our biological processes work to keep our weight at some genetically-determined level
what is the most critical factor that determines body weight
a persons tendency to engage in physical activity

hours spent watching television is correlated with obesity
for adults, tv watching seems worse than time spent in front of computer screens, perhaps because it is more difficult to snack when typing or texting
-for children, the amount of time spent in front of tv or computer screens is associated with higher obesity rates
eating habits that support obesity may be handed down from one generation to the next

and don’t believe anyone who tries to sell you a weight loss program that lets you eat whatever you want
- maintaining a healthy body weight is difficult, so be wary of products that promise a quick and easy solution to such a difficult challenge
- staying fit requires time, discipline, hard work, and careful planning
- ppl eventually crave the work out and healthy food like they used to crave junk food and sitting around
