The extent of breast feeding in Dunedin 1974-83

This study examined breast feeding practices in Dunedin, and aimed to identify determinants of breast feeding in this population. Infants' records were used for a 10 year period (1974-83) from the Royal New Zealand Plunket Society. An upward trend in breast feeding prevalence was observed. Breast feeding was more common in mothers of high socioeconomic status (p less than 0.001), in those who were living with a spouse (p less than 0.001) and when mothers attended parental classes (p less than 0.025). First time mothers tended to breast feed for a shorter time (p less than 0.05). Early introduction of other foods shortened the duration of breast feeding (p less than 0.001). The increase in breast feeding which has occurred in many parts of the western world was also found in Dunedin.
