Lav fødselsvaegt er associeret med ikke-insulinkraevende diabetes mellitus hos diskordante monozygote og dizygote tvillingepar

Previous studies have demonstrated an association between low weight at birth and risk of later development of non-insulin dependent diabetes mellitus (NIDDM). It is unknown whether this association may be due to an impact of intrauterine malnutrition per se, or whether it may be due to a coincidence between the putative "NIDDM susceptibility genotype" and a genetically determined low weight at birth. We traced original midwife birthweight record determinations in a group of monozygotic (n = 14 pairs) and dizygotic (n = 14 pairs) twins who phenotypically appeared discordant for NIDDM at a mean age of 67 and 64 years respectively. Birthweights were lower in the NIDDM twins compared with both their identical and non-identical non-diabetic co-twins respectively (p
