Many medical experts are saying that when people get richer (and taller) they are getting sicker and by that suffering from more chonic diseases than people with lower socioeconomic status. When you look at ethnically homogeneous nations and then compare them to each other this is quite obvious. Poor people are generally suffering from infections and rich people - cancer and hearh disease. Also, controling for socioeconomic status, taller people are still more prone to cancer.
Mind citing the study you are referencing?
https://hqlo.biomedcentral.com/articles/10.1186/1477-7525-12-58 This one seems to state the opposite of what you are saying,
"Among adults with a chronic disease, most ‘moderate or severe problems’ are reported more often in the low (compared with the high) educational group."
"Low SES groups seem to be faced with a double burden: first, increased levels of health impairments and, second, lower levels of valuated HRQL(health-related quality of life) once health is impaired."
Relating to ethnically homogeneous groups, do you mean hypertension in China ?
https://www.sciencedirect.com/science/article/pii/S1043951X11000848 "Correlations between SES and various measures of hypertension are examined. ► We find no significant wealth and education gradients in hypertension prevalence."
"Wealth plays some roles in improving the treatment and control of hypertension."
Instead it seems being affluent improves your health conditions, which might seem dubious to you. Btw why are you regurgitating the fact that tall people are prone to cancer, your schadenfreude against tall people is apparent from your posts.
https://www.reddit.com/r/askscience/comments/4hxc06/do_taller_people_die_younger/?utm_medium=organic&utm_source=google_rich_qa&utm_campaign=google_rich_qa"There probably is an association between being tall and earlier death. One recent paper found a relative risk of 1.006 per cm of height, which is a very small though statistically significant effect.
Note, though, that other studies have found the reverse, and hypothesized that being tall is an indicator of having better nutrition and better health during childhood, which in turn should lead to longer lifespan. This paper argues that studies that did find that had various statistical issues, particularly that they didn't track the same group of people over very long periods but used different age cohorts instead. They argue that you need to track thousands of people, preferably a fairly homogenous group (in this case, men of Japanese ancestry) for many decades to pick up on the statistical signature.
In particular, the effect doesn't kick in until people are already quite old:
We compared survival curves between participants who were 165 cm or taller in height, those who were 158 cm or shorter, and those whose height was between 158 cm and 165 cm. We found no significant difference between the groups for survival prior to the age of 80 years. Survival curves in the follow-up for these three groups of people differed significantly between age 80 and 95 years ...
(My emphasis)
Consistent with the taller-people-had-healthier childhoods hypothesis, they found that even though taller men tended to die younger, they also tended to be healthier in old age - less risk of dementia, stronger grip strength, etc.
The mortality effect was driven mainly by cancer, and one hypothesis is that because taller people have more growth factors they may be more prone to cancer. Another is that it's linked, at the genetic level, to the calorie reduction model of longevity.
The mortality effect is so small, and there are so many complicating effects, that it's not something any one person will be able to notice individually -- that is, your observation that old people seem to be smaller is almost certainly due to confirmation bias and confounding effects (for example, on average people are getting taller, so older people were smaller on average)."
Seems isn't that big of a deal after all, only when you factor in the population and statistics. Besides I would rather live 50 years being happy and tall (Height and satisfaction) rather than with diminutive stature and bittersweet transient contentment.
