Technical Note: Increase the proportion of babies with a healthy birth weight

Increase the proportion of babies with a healthy birth weight

DESCRIPTION:

This indicator measures the proportion of new born babies with a weight appropriate for their gestational age.

SOURCE:

The data used for the indicator are obtained from the Scottish Morbidity Record 02 (SMR02) submitted by maternity hospitals to ISD.

The data gathered are published by ISD on their website:

Births in Scottish Hospitals

A wide range of information is collected on the SMR02 including the babies' sex, gestational age and weight.  There is no legal requirement to submit these data to ISD. However, the level of submission falls only slightly short of the known total number of births occurring each year.

The data used in this indicator are produced by comparing the birthweights and gestations of births in Scottish hospitals with a set of standard tables based on UK-WHO Child Growth Standards (http://www.rcpch.ac.uk/child-health/research-projects/uk-who-growth-charts).  This is a change to previously published data on appropriate birthweight for gestational age which used standard tables derived from Scottish reference data.

DEFINITIONS:

A baby is considered to be of healthy birthweight (a weight appropriate for its gestational age) when it lies between the 5th and 95th centile for weight at its gestational age.  Babies whose birthweight is above the 95th centile are considered ‘large for gestational age’, while those below the 5th centile are considered ‘small for gestational age’.

Gestational age is a way of expressing the age or development of a baby. It is typically based on an antenatal ultrasound scan, however, it may also be estimated from the number of weeks since the mother's last normal menstrual period.

CRITERIA FOR RECENT CHANGE ARROW:

Any difference within +/- 0.5 percentage points of last year's figure suggests that the position is more likely to be maintaining than showing any change. A decrease of 0.5 percentage points or more suggests the position is improving; whereas an increase of 0.5 percentage points or more suggests the position is worsening.
