The epidemiology of XXXX in south-western Ohio--1970-1979.

@entity1 @entity3570 @entity600
Multiple epidemiological variables of 131 @entity1 with @entity3570 born during 1970 and 1979 in a seven-county urban/rural region of south-western Ohio were analyzed retrospectively via personal interviews, hospital and clinic records, and birth and stillbirth certificates. The estimated incidence of @entity3570 was 0.69/1000. It did not vary over the 10 years, seasonally, or in the urban vs. rural areas. The incidence for whites was three times that for non-whites. Reporting of @entity3570 on the birth certificate was found for 52 per cent. Fetal loss in the @entity1 's mothers was similar to that for controls. However, there was a high number of therapeutic abortions just prior to the conception of the @entity1 with @entity3570 . Oral contraceptives were used in the early months of the affected pregnancy more frequently than in controls. Recurrence risk was 3.2 per cent. Almost 12 per cent of the @entity1 with @entity3570 had other major @entity600 . Even when the deceased probands were discounted, the @entity600 rate was higher than in the general population. Siblings of affected @entity1 had a less impressive but still increased rate of @entity600 .
