The global challenge of weight-related issues in kidney disease

A new nationwide study from Japan spanning a 14 year study period has revealed an increasing trend of overweight and obesity in patients with the incident end-stage kidney disease (ESKD). Although, underweight individuals remain prevalent in this patient population, the study highlights that excessive weight and obesity in patients with the incident ESKD is a shared global challenge. Consequently, the study suggests the need for public health strategies to address the global obesity epidemic as well as underweight individuals in incident ESKD populations.

"The global prevalence of overweight and obesity has been rising steadily, this trend is apparent in the United States and Italy among patients with incident ESKD," said Dr. Wakasugi, the corresponding author of the study. Japan is an exception to these trends; although the general male population demonstrates a similar increase, the prevalence of overweight and obesity have declined in young and elderly female populations.

This raises a question as to whether the prevalence of overweight/obesity in the incident ESKD population also follows a similar pattern (i.e. an increasing trend in men but not in women), as in the case of the United States and Italy where the trend observed in the incident ESKD population mirrors that in the general population.
