The relationship between obesity and mental health was investigated, u
sing data obtained from 1,660 persons selected as representative of 11
0,000 inhabitants of a residential area of New York City, In addition
to confirming the previously noted relationship between obesity and ag
e, preliminary analysis revealed a striking relationship between obesi
ty and socioeconomic status of origin, The prevalence of obesity was 7
times higher among women reared in the lowest social class category a
s compared with those reared in the highest category, Scores made by t
he obese respondents on 9 mental health indices were compared with sco
res made by individuals of average weight, The obese respondents made
more pathological scores on 8 of the 9 measures and on 3 of these the
difference was statistically significant (''immaturity,'' ''rigidity,'
' and ''suspiciousness'').
