Las mujeres de 18 años obesas o con sobrepeso se enfrentan a un riesgo incrementado de ser sometidas en el futuro a sustitución de cadera, según muestran investigadores de Harvard en el "American Journal of Medicine".
Basándose en datos del Nurses' Health Study, que incluye a 121.000 participantes, estiman que la obesidad en la adolescencia supone multiplicar por 2,5 las probabilidades de desarrollar artrosis severa de cadera en el futuro, suficiente como para necesitar una prótesis. En el caso de que la obesidad sea mórbida índice de masa corporal superior a 35-, el riesgo se multiplica por 7.
Del total de enfermeras participantes en este gran estudio, que se inició en 1976, 568 fueron sometidas a sustitución de cadera en los años noventa debido a la artrosis.
De sus resultados concluyen que el índice de masa corporal que presenta la mujer a la edad de 18 años constituye un importante predictor del riesgo.
