Poverty is often cited as contributing to poor health. Now, in an unusual approach, researchers have calculated how many people poverty kills and presented their findings, along with an argument that social factors can cause death the same way that behavior like smoking cigarettes does.
In an article published online for the June 16 issue of The American Journal of Public Health, scientists calculated the number of deaths attributable to each of six social factors, including low income.
To estimate the number of deaths caused by each factor, the scientists reviewed 47 earlier studies on the subject, combining the data in a meta-analysis. The studies were generally based on large national surveys like the National Health and Nutrition Examination Survey, a continuing study by the Centers for Disease Control and Prevention.

One more reason why studies with positive health results for moderate drinkers vs. abstainers are not correct.

As with underage drinking, social factors can help predict excessive drinking among older adults, according to new research from Rudolf H. Moos of the Department of Veterans Affairs Health Care System in Palo Alto, Calif.
Moos and colleagues studied 719 men and women ages 55 to 65 over a 20-year period and found that those with more money, a more active social life, and friends who approved of drinking were more likely to engage in risky or excessive drinking. (Source: Join Together, 2/2/10)

Among older drinkers, social factors can both predict and sustain alcohol misuse.
Social factors have consistently been implicated as a cause of vulnerability to alcohol use and abuse. The reverse is also true, in that individuals who engage in excessive drinking may alter their social context. New research on drinking among older adults has found that older adults who have more money, engage in more social activities, and whose friends approve more of drinking are more likely to engage in excessive or high-risk drinking.
