Abstract

BACKGROUND:

Community cohort studies and meta-analyses of randomized trials have shown a relation between low or lowered cholesterol and death by violence (homicide, suicide, accident); in primates, cholesterol reduction has been linked to increased behavioral acts of aggression (Kaplan J, Manuck S. The effects of fat and cholesterol on aggressive behaviour in monkeys. Psychosom. Med 1990;52:226-7; Kaplan J, Shively C, Fontenot D, Morgan T, Howell S, Manuck S et al. Demonstration of an association among dietary cholesterol, central serotonergic activity, and social behaviour in monkeys. Psychosom. Med 1994;56:479-84.). In this study we test for the first time whether cholesterol level is related to commission of violent crimes against others in a large community cohort.

METHODS:

We merged one-time cholesterol measurements on 79,777 subjects enrolled in a health screening project in Varmland, Sweden with subsequent police records for arrests for violent crimes in men and women aged 24-70 at enrollment; and with information on covariates. We performed a nested case control comparison of cholesterol in violent criminals - defined as those with two or more crimes of violence against others - to cholesterol in nonoffenders matched on age, enrollment year, sex, education and alcohol, using variable-ratio matching, with a nonparametric sign test.

RESULTS:

One hundred individuals met criteria for criminal violence. Low cholesterol (below the median) was strongly associated with criminal violence in unadjusted analysis (Men: risk ratio 1.94, P=0.002; all subjects risk ratio 2.32, P<0.001). Age emerged as a strong confounder. Adjusting for covariates using a matching procedure, violent criminals had significantly lower cholesterol than others identical in age, sex, alcohol indices and education, using a nonparametric sign test (P=0.012 all subjects; P=0.035 men).

CONCLUSIONS:

Adjusting for other factors, low cholesterol is associated with increased subsequent criminal violence.

An email sent to Kristin Jacobson, Assistant Professor, University of Chicago Medical School Dear Prof. Jacobson, I was just leafing through my University of Chicago Magazine this evening when I came across the article summarizing your new grant. I have to say I was amazed. Though the author tiptoed around the area under investigation, you are entering some very choppy waters. The attempt to identify the genetic and biological contributions to anti social behavior and cognition is normally considered taboo, since it inevitably ventures into racial variables. Though I am familiar with some work reported in press releases and abstracts of journals, as you can see from my weblog, most researchers, considering the downside, tend to avoid such studies, even with the best of intentions. I can't help be reminded of the unfortunate lesson of Chicago's Dr. Bruce Lahn, with whom you undoubtedly have discussed your research interests. As was noted several years ago in the Wall Stre...

Brain imaging study suggests risk-taking behaviors can be contagious

BY CALIFORNIA INSTITUTE OF TECHNOLOGY ON APRIL 14, 2016  COGNITION Why do we sometimes decide to take risks and other times choose to play it safe? In a new study, Caltech researchers explored the neural mechanisms of one possible explanation: a contagion effect. The work is described in the March 21 online early edition of the Proceedings of the National Academy of Sciences . In the study led by John O’Doherty, professor of psychology and director of the Caltech Brain Imaging Center, 24 volunteers repeatedly participated in three types of trials: a “Self” trial, in which the participants were asked to choose between taking a guaranteed $10 or making a risky gamble with a potentially higher payoff; an “Observe” trial, in which the participants observed the risk-taking behavior of a peer (in the trial, this meant a computer algorithm trained to behave like a peer), allowing the participants to learn how often the peer takes a risk; and a “Predict” trial, in which the ...

Temperamental differences by race

Excerpted from: Solving The African IQ Conundrum : "Winning Personality" Masks Low Scores By J. Philippe Rushton VDare August 12, 2004 https://www.stormfront.org/forum/t148855/ Over a century ago, Sir Francis Galton initiated research into individual and race differences in intelligence and temperament. He was the first to propose the study of human twins and of selective breeding in animals to disentangle the effects of heredity and environment. And it was Galton—who spent several years exploring in what is now Namibia as a young man—who first contrasted the talkative impulsivity of Africans with the taciturn reserve of American Indians, and the placidity of the Chinese. Galton further noted that these temperament differences persisted irrespective of climate (from the frozen north through the torrid equator), and religion, language, or political system (whether self-ruled or governed by the Spanish, Portuguese, English or French). Anticipating later studies of tr...
