- W79951030 abstract "The characteristics of a defined population of 16 villages with 3,500 people in the Sepik District of Papua, New Guinea from January 1973 to December 1969 are provided as part of a large longitudinal survey planned to cover a full generation in order to determine the effect on health of contact from a Western civilization with a previousl y isolated Melanesian society. Study results are organized into 2 parts-the first part dealing with live births, stillbirths, fertility, maternal age and age-parity analysis, and the second part presenting findings on social factors such as birth interval, illegitimate births, adoption, widowhood, polygeny and divorce. Study results included the following information: 1) The birth rate was 35 per 1,000. A decrease of 50% in the infant mortality rate during the period of study apparently caused a decline in the birth rate; 2) Fertility was relatively low and substantially less than the biological potential. Late marriage, consequent late age for first children (23), and maintenance of a rigid birth interval (a mean of 3.3 years) accounted for low fertility; 3) A birth interval of less than 1.5 years is met with severe disapproval unless it follows the early death of the previous child; 4) Children are highly valued; illegitimate children are readily abosorbed into the extended family and children are freely adopted from one family to another. The true divorce rate (excluding unconsummated arranged marriages) was extremely low." @default.
