Waves 1-4 were carried out by Office for National Statistics Social Survey Division. Wave 5 was carried out by Office for National Statistics and Institute of Child Health.

Abstract:

The survey aimed to:
establish the feeding practices in families for infants from birth to 15 months of age;
identify the reasons why babies are fed as they are, and determine what influences mothers to make their choices about infant feeding;
identify the sources and quality of information and support provided to mothers;
examine the growth of babies and relate this to feeding practices.
Wave 5 data, made available in this second edition, were collected during the fifth stage of the survey. This fifth wave followed up the Asian children in the study when they were about 2 years old to:
evaluate the effect of diet on the development of anaemia in young Asian children;
explore the relationship between previous feeding history, current daylight exposure and vitamin D status;
assess the impact of infection (indicated by acute phase protein values) on indicators of iron status.

The UK Data Archive also holds a series of five-yearly Infant Feeding Surveys, 1985-, conducted using a wider sample across the United Kingdom, under GN 33251.

Main Topics:

Waves 1-4:
Topics covered by the data include:
Breastfeeding - incidence, prevalence and duration.
Choice of feeding method.
Bottle feeding - prevalence, type of non-human milk given, hygiene practices, help with cost of milk.
Ante-natal care and advice.
Feeding problems and sources of advice during first 15 months.
Solid food - age of introduction, type of food eaten and frequency, feeding problems.
Drinks - types of drinks other than milk, frequency of consumption of different types of drink.
Vitamin supplements given.
Body measurements - weight, supine length, head circumference, mid upper-arm circumference.
Wave 5:
The file for wave 5 contains:
Data from interviews with mothers covering: information on the child's milk drinking habits; consumption of other food and drink which could influence iron status and vitamin D; consumption of vitamin supplements; exposure to sunlight; recent infection.
Results of analysis of a blood sample taken from the child at the time of the interview.
It is possible to carry forward other variables from waves 1-4 of the survey by matching serial number.

Coverage:

Time Period Covered: October 1994 - January 1996
Dates of Fieldwork: The data were collected in five stages:
Wave 1 : October 1994 - January 1995 (babies on average 9 weeks old).
Wave 2 : January 1995 - March 1995 (babies on average 5 months old).
Wave 3 : May 1995 - July 1995 (babies on average 9 months old).

Country: England
Spatial Units: No spatial units
Observation Units: Individuals
Kind of Data: Numeric data; Individual (micro) level

Universe Sampled:

Location of Units of Observation: National
Population: The babies studied were those born between August 15th and November 11th 1994, to mothers living in the 41 selected local authority areas who had defined themselves as being of Bangladeshi, Indian or Pakistani origin. A sample of babies born to white mothers living in the same areas was also included for waves 1-4.

Methodology:

Time Dimensions: Cross-sectional (one-time) study
Sampling Procedures: Multi-stage stratified random sample
Sampling procedures are discussed in detail in the survey report.
Number of Units: Weighting factor (ETHWT2) was used to take account of the sub-sampling of Pakistani babies for part of the sampling period.
(A) 2000 (target) 2382 (obtained) at stage 4 (November 1995 - January 1996).
(B) 2373 (obtained) Weighted sample size at stage 4
(C) 1750 (target) 1057 (obtained) Wave 5
Method of Data Collection: Face-to-face interview; Clinical measurements; Physical measurements; Mothers were interviewed face-to-face on five occasions. A blood sample was taken from the baby at wave 5, and standard anthropometric measurements of babies were taken at each interview.
