Birth Weight and Future Life-span in Finnish Triplets | Chapter 02 | Innovations in Medicine and Medical Research Vol. 1
Aims:
Interest in the distribution of birth weight arises because of the association
between birth weight and the future health of the child. A common statistical
result is that the birth weight distribution differs slightly from the Gaussian
distribution.
Methods:
A standard attempt has been done to split the distribution into two components,
a predominant Gaussian distribution and an unspecified “residual” distribution.
Results:
We considered birth weight data among triplets born in Finland in 1905-1959 and
compare the birth weight among stillborn and live-born triplets. The stillbirth
rates are 119.1 per 1000 births for males, 124.6 for females and 121.8 for all.
The sex differences are not significant. The still birth rate for the period
1905-1930 was 119.5 and for the period 1931-1959, 124.2. We identified a strong
association between birth weight of the triplets and their survival. The weight
distribution for male triplets is described well by the Gaussian curve, while
for females a slight deviation from the Gaussian distribution is discernible.
