The 3,339 first admissions with alcoholic diagnoses to the Ohio state public mental hospital systen during the 3 1/2-year period July 1958-Dec. 1961 constituted a rate of 17.5/100,000 of the metropolitan population aged 25-64 and 24.4 of the nonmetropolitan population. The rate was higher among (a) males (metropolitan, 28.2; nonmetropolitan 43.7) than females (7.2 and 5.4); (b) male nonwhites (metropolitan, 61.6) than whites (24.2) (c) the single males (60.8) than the married (30.2), with the separated and divorced having still greater rates; (d) those with at most an elemental school education (metropolitan males, 40.0; nonmetropolitan, 53.9) thar those with 4 years of high school (21.2 and 28.6) or 1 or more years of college (10.1 and 14.7); (e) male laborers (metropolitan, 102.1; non-metropolitan, 175.3) than the other occupational groups, the nonmetropolitan rate being higher than the metropolitan in every occupational category except service workers whose admission rate (54.7 and 47.1) was second only to laborers. An important finding at variance with a like analysis of admissions a decade earlier was that white male residents in metropolitan areas now had lower rates (24.2) than their nonmetropolitan counterparts (43.2). The phenomenon of higher non-metropolitan rates can perhaps be explained by the increase in state hospital facilities and the absence of other psychiatric hospital resources. Of the 16 nonmetropolitan counties with the highest admission rates, 5 contained a state mental hospital and others were adjacen counties. None of the 16 with the lowest admission rates contained a state mental hospital. The admission rate was higher among native-born white males (metropolitan, 24.2; nonmetropolitan, 42.3) than among the foreign-born (7.9 and 19.0) and the natives born in other states (40.0) than those born in Ohio (27.0). Of the nonwhites, 69%, and of the whites, 49% were under age 45; the peak ages of admis sions of the whites were 45[long dash]49, of the nonwhites, 40-44. Of the 3,339 admissions, 83% were male and 17% female, the same as the sex distribution in the 1950 study. Contrary to widespread belief, there was no indication of a disproportionate increase in alcoholism among females; when all ages are considered, the male:female ratios ranged from 1.5:1 to nearly 18:1.
