Low birth weight and end-stage renal disease: demographic analysis by region in Japan

Abstract

The present study, relating regional distribution between LBW and ESRD dynamics in a nationwide population of Japan, revealed that the marked regional differences in the incidence of ESRD within Japan could be explained by a similar regional distribution in the incidence of LBW.

Hemodialysis Patients Born With a Low Birth Weight Should Have a Different Time Course of Kidney Diseases Than Those Born With a Normal Birth Weight

“…However, the mean age of dialysis patients with a LBW may be younger as a consequence of an earlier start of dialysis in comparison to those with a NBW as shown in this study. Although two of three of our hypotheses might be supported by this study, one hypothesis that the duration from the onset of kidney disease to HD induction is shorter in HD patients with a LBW history than those with a NBW history was denied However, we do not think that only this data can explode previous results that showed the effect of LBW on the progression of CKD . A Pearson's correlation analysis of all analyzable participants also showed no correlations with the birth weight (Table ).…”

“…Previous studies revealed that a low birth weight may be a risk factor of kidney disease or end‐stage kidney disease . The current study tried to assess whether the birth weight affected the time course of kidney diseases by a multicenter questionnaire survey.…”

“…In addition, the risk of end‐stage kidney disease increases in individuals born with low birth weight . In Japan, we and others recently reported the association between low birth weight and the risk of end‐stage kidney disease by the ecological study .…”

Effect of birth weight on adulthood renal function: A bias‐adjusted meta‐analytic approach

“…On the other hand, there were five studies that had assessed renal function at aged 50 years and above, and the rest were at middle age (30–50 years). Four studies did not mention age clearly . Two studies included twins .…”

“…A study from Singapore also reported higher odds (2.09) of CKD among sixth grade school children with LBW . A study from Japan has also demonstrated a positive correlation between the annual incidence of LBW and of ESRD . Such correlations could not be estimated for other Asian countries, perhaps due to poor national birth registration systems as well as unavailability of life course health status registers .…”
