Intelligente
Kinder werden später oft Vegetarier
Mehr
als 8.000 Briten beteiligten sich an einer Studie bei der ein
Forscherteam um Catharine R Gale von der Universität Southampton
versuchte herauszufinden ob sich der Intelligenzquotient eines
zehnjährigen Kindes darauf auswirkt, dass sich dieses Individuum
im Alter von 30 Jahren als Vegetarier bezeichnet.
366 Teilnehmer (4.5%) gaben bei der Befragung an Vegetarier zu
sein. Von diesen räumten aber 123 (33.6%) ein, dass sie gelegentlich
Fisch oder Geflügelfleisch essen.
Der
in der Kindheit dokumentierte Intelligenzquotient blieb bei den
Analysen der entscheidende Faktor für die tatsächliche Entscheidung
Vegetarier zu werden - auch nachdem aus den Statistiken
Faktoren wie Sozialstatus, Bildungsniveau und Geschlecht herausgerechnet
wurden. Offenbar setzt der Entschluss mit dem Fleischverzehr aufzuhören
eine höhere Intelligenz voraus.

Objective To examine the relation between IQ in childhood
and vegetarianism in adulthood.
Design Prospective cohort study in which IQ was assessed
by tests of mental ability at age 10 years and vegetarianism by
self-report at age 30 years.
Setting Great Britain.
Participants 8.170 men and women aged 30 years participating
in the 1970 British cohort study, a national birth cohort.
Main outcome measures Self-reported vegetarianism and type
of diet followed.
Results 366 (4.5%) participants said they were vegetarian,
although 123 (33.6%) admitted eating fish or chicken. Vegetarians
were more likely to be female, to be of higher social class (both
in childhood and currently), and to have attained higher academic
or vocational qualifications, although these socioeconomic advantages
were not reflected in their income. Higher IQ at age 10 years
was associated with an increased likelihood of being vegetarian
at age 30 (odds ratio for one standard deviation increase in childhood
IQ score 1.38, 95% confidence interval 1.24 to 1.53).
IQ
remained a statistically significant predictor of being vegetarian
as an adult after adjustment for social class (both in childhood
and currently), academic or vocational qualifications, and sex
(1.20, 1.06 to 1.36).
Exclusion
of those who said they were vegetarian but ate fish or chicken
had little effect on the strength of this association.
Conclusion Higher scores for IQ in childhood are associated
with an increased likelihood of being a vegetarian as an adult.
