Los autores, dirigidos por el Dr. David Nelson, del Instituto Nacional del Cáncer, muestran, por ejemplo, que se ha mejorado notablemente en ciertas medidas de salud, entre ellas el uso de cinturones de seguridad o las vacunaciones en personas de edad avanzada. En el otro lado de la balanza citan el incremento de la incidencia del tabaquismo en 14 de los 47 estados investigados y de la obesidad en todo el país.
El estudio ha consistido en entrevistar por teléfono mensualmente a ciudadanos adultos de 49 estados. En total, los encuestados han sido más de 182.000.
Entre los aspectos positivos, además de los citados, comentan el incremento de la proporción de mujeres mayores de 40 años que se han sometido a mamografías.
En cuanto a los negativos, además del tabaquismo y la obesidad, mencionan que es necesario promover más el cribado del cáncer colorrectal y del colesterol, que han aumentado solamente en 13 de los estados investigados.
