Development of birth weight in Austria from 1970-1995.
We analysed the development of birth weight of all Austrian live births in the period 1970-1995. The relationship between birth weight and the variables maternal age, length and sex of the newborn and year of birth is described by means of a linear regression model. Over the 26 years an increase of up to 60 g was observed in the mean birth weight. This positive trend may partly be due to the extensive use of the maternity care program ("mother-and-child Passport") introduced in 1974. Maternity payment was made to the mother it she underwent at least five examinations within the antenatal care program. This payment was reduced from 15,000 AS in 1996 to 2000 AS as from January 1st 1997, a measure which may lead to a reduction in the use of this maternity care program, with consequent negative implications for the morbidity of both mother and child and for the positive trend of birth weight development over the past decades.
