Chapter 12 Flashcards
who lives longer women or men?
women
what was the life expectancy for men and women in the 1900 and in 2016 in the US? (shows sex differences in longevity of life)
1900: men= 46.3, women= 48.3
2016: men=76.1, women= 81.1
(30 year increase)
generally, which groups live longer, marginalized groups or dominant groups? what is the exception to this pattern?
dominant (white, heterosexual people)
(latinos/latinas are the only exception to this pattern)
what is the latino paradox?
tendency for latinx americans of the US to have health outcomes as good as, if not better than, those of non- latinx white people in the US despite tending to have a lower average income and less education. but health advantages decrease when latinx people become acculturated to the US lifestyle
why do transgender individuals have a shorter life expectancy than cisgender?
stressors (discrimination)
health risks (violence, lack of adequate health care, reliance on drugs)
what were common causes of death in 1900?
infectious diseases (pneumonia, tuberculosis)
what was the common cause of death in 2010? why?
diseases of old age (heart disease, cancer, alzheimers)
because vaccines, antibiotics, refrigeration (slows bacteria growth) have all been created
what is the morbidity mortality paradox?
a phenomenon in which women tend to have higher rates of sickness (morbidity) than men, while men tend to experience death (mortality) earlier than women
in 2015 what did men suffer from in comparison to women?
life threatening conditions more often than women but women suffer with chronic conditions (arthritis, autoimmune diseases…)
what supports the argument that men are healthier?
men report having better health than women (though they dont live as long)
women spend more on health related services over their life due to chronic conditions (migraines, fibro)
what supports the argument that women are healthier?
mens death rates are higher
though more women report not being as healthy than men, this could be because men are told to suppress any signs of weakness
boys are more likely to die than girls
boys and men get more infections
what 2 broad biological factors shape health and contribute to sex differences in health and longevity?
genetic factors (two X chromosomes, telomeres)
hormonal influences (testosterone and estrogen)
how does having two X chromosomes provide a health advantage to girls and women?
sex chromosomes (XX or XY) can sometimes carry genetic mutations (muscular dystrophy or hemophilia) which are passed down through the X chromosome, the disease producing gene on the X chromosome can get over rided by the other X chromosome to prevent expression of the gene
thus men are more vulnerable to X- linked diseases
what is hemophilia?
sex- linked, genetic blood clotting disorder which can cause excessive bleeding
what are telomeres?
disposable DNA sequences at the ends of chromosome strands that protect the remaining genes on the chromosomes during cell division (like the caps on the ends of shoelaces that prevent fraying)
what is different between male and female telomeres?
at birth mens and womens telomeres are the same, but mens shorten faster which means that male cells age faster
how do hormones influence sex differences in longevity?
high doses of testosterone decrease “good” cholesterol and increase “bad” cholesterol (increasing heart disease)
testosterone suppresses the bodys immune system
estrogen provides health benefits (increases cardiac output
estrogen increases the expression of longevity associated genes but can also increase certain forms of cancer
what is evolutionary theorists reasoning behind the fact that women outlive men?
mens bodies evolved to prioritize procreation over immunity
men tend to “live hard, die young” this is due to testosterone. men compete aggressively for mates in order to have reproductive success (“live hard”) however, high testosterone also correlates with immune suppression and an increased vulnerability to infection (“die young”)
women contribute more to infant nourishment, fighting disease and repairing damaged cells
what kinds of things do individuals DO that influence their health in positive and negative ways?
accidents and risky sex
smoking, alcohol use, and diet
physical activity and exercise
what does risky behavior consist of? who is more influenced by risky behavior, women or men?
electrical repairs, climbing on roofs, white water rafting, motorcycle racing, bungee jumping, reckless driving,
men
why are men more prone to traffic accidents than women?
not wearing seatbelts, speeding and driving under the influence
why is sexual activity considered risky behavior?
unprotected sex, sex with a stranger, sex while under the influence are risky because they can increase the chances of sexually transmitted diseases, pregnancy and violence
do women or men contribute more to sexually risky behavior?
no sex difference generally
as teenagers who is more likely to engage in sexually risky behavior, men or women? during post college years?
teenager:men
post college: women
who is more prone to HIV?
in the US: men
worldwide: women account for half of cases
when does HIV occur in men normally? women?
men and transwomen: occurs during same sex sexual activity
women: occurs during heterosexual activity
what percentage of transwomen are HIV positive in the US?
25%
what are risk networks?
extended networks of individuals with whom people have sexual contact or engage in other risky practices (e.g. intravenous drug use) that can transmit disease
what do risk networks help explain?
why black and latinx people account for 70% of new HIV diagnoses though they are only 29% of the population
according to risk networks why do black and latinx people account for the majority of new HIV diagnoses?
likelihood of HIV infection increases as a function of both individual risks (e.g. having unprotected sex) and the proportion of infected sexual partners in a persons risk network, so even if black and latinx people do not take more individual risks than white people they may still exhibit higher rates of HIV infection than white people if they have relatively high concentrations of HIV infected sexual partners in their risk networks
what are highly active antiretroviral therapies?
very expensive drug treatments that reduce the risk of dying from HIV related causes
who smokes more cigarettes, men or women?
men, but the sex difference continues to decline
