Abstract


For the purpose of studying the infant nutrition a study was conducted by the Author on 1,034 women, who have experienced live-birth before April, 1972, residing in Kumho Dong, Sungdong-gu, Seoul City during the period from October to December of 1972. The results and findings obtained from the study are summarized as follows:
1) General characteristics of the women:
The largest age group among those interviewed was 30∼34 (31%), and the average age of the sample was 33 years, 57% of the women interviewed had a primary school education or less, while 43% had attended middle school or beyond. In terms of standard of living, the great majority was lower class, accounting for 72% of the sample.
The average age at marriage was 22 years, the average age at first childbirth was 23.8 years, and the average duration or marriage was 11 years. The average number of pregnancies was 4.0 and the average number of births per woman was 2.9. Fetal wastage amounted to 27.5% and the rate of induced abortion was 0.9 per woman.
The average number of children was 2.9, the number of surviving sons averaged 1.5 and the average number of additional children desired was 0.3.
2) Period of observation:
Those whose last pregnacy terminated at least 13 months prior to the interview accounted for 94% of the sample. The average amount of time elapsed since the end of the last pregnancy was 37 months.
Ninety-six percent gave birth to their last child at least 13 months prior to the interview. The average period since was 49 months.
3) Duration of lactation:About 6 percent of the sample did not breast feed their children at all. Of these, the greatest proportion (64%) gave "insufficient breast milk" as their reason. Nineteen percent of the sample were currently nursing children at the time of the survey, while 75% had completed lactation. The lactation period for the greatest number (35.1%) fell in the range of 13∼18 months, and averaged 18 months.
4) Staple food during infancy:
During the first six months after birth, the major source of nutrition was breast milk in 88.2% of the cases, artificial milk in 11.3% of the cases, and other foods for the remaining 1%. For the period from the 7th to the 12th month, the major food was breast milk for 81% of the sample, artificial milk for 9.1% and other foods for 10.3%. The number relying on breast milk through early and late infancy is thus quite high.
5) Ideal duration of lactation:
About 4 percent of the sample felt that the ideal lactation period was six months or less, 8.1% felt that 7∼9 months was ideal, 43.0% felt that 10∼12 months was ideal while 45.0% felt that 13 months or more was necessary. The average ideal lactation period was 12.3 months.
6) Actual lactation period and ideal lactation period:
The actual lactation period varied with ideas regarding ideal lactation period. Of those who felt that the ideal lactation period was 0∼3 mouths, 21% weaned their children within 6 months, while only 1.5% of those who felt that the ideal lactation period was 10∼12 months weaned their children within the same period. Of the latter, 26% continued lactation for 25 months or more.
The average lactation period was 18 months, 5.7 months, longer than the ideal lactation period of 12.3 months.
7) Cow´s milk:Twenty two percent of the women interviewed fed, their children with both breast milk and cow´s milk, 17.5% starting the use of cow´s milk within the first six months and the remaining 4.3% starting thereafter.
8) Supplementary foods:
Fourty six percent of the sample (450 persons) used supplementary foods and 54% did not. Of the 46% who used supplementary foods, 15.1% started within the first 6 months and the remaining 31.1% did so thereafter. The average time at which use of supplementary foods began was 7.0 months.
