Analizaron datos de 116.564 mujeres participantes en el Nurses' Health Study, que comenzó en 1976, cuando tenían entre 30 y 55 años de edad.
En estos 24 años de seguimiento, fallecieron 10.282 mujeres, 2.370 por causa cardiovascular, 5.223 por cáncer y 2.689 por otras causas.
Explican que, al contrario que otros estudios, en este se ha observado que un alto nivel de actividad física no elimina el riesgo de muerte prematura asociada a la obesidad; y por otro lado señala que la delgadez no elimina el mayor riesgo de muerte asociado al sedentarismo.
Los resultados indican que las mujeres obesas y sedentarias presentan un riesgo 2,5 veces mayor de muerte prematura que las activas y delgadas.
