while ($row = mysql_fetch_array($result))

list($checked)=mysql_fetch_row(mysql_query("select user_id from User_Category where
user_id='$current_user' and category_id='".$row["category_id"]."'"));
$checked=$checked?" checked":"";

}
Hope this helps. You'll probably have to change a few letters here and there, but it
should work in the end.
If the costs of connecting to the MySQL server are big then you could grab the
categories for the current user prior to the loop, store them into an array and then
echo "checked" if in_array().
