Methods. Data from the National Health Interyiew SuNey 1994 of US childrenaged 0 to 18 yea6 (n=33911)were used. SES was measured as parenta l educa't ion. Chi ld heal th measures inc luded overal l heal th. l imi tat ions. and chronic andacute ch ldhood condi t ions.
Aesu/ts. For overall health, activity and schoo limitations, and chronic circu a-torycondi t ions, the ike l lhood ofpooroutcom€s in€reased as parenta leducat iondecreased. These relationships wefe stronger among White and Blackchildren, andweaker or nonexis lent arnong Nispanic and Asian chi ldren.
