In the Wosera area of Papua New Guinea, the nutritional status of 899 women of child-bearing age (measured by weight, body mass index, and skinfolds thickness) showed a strong negative correlation with parity, independent of age. This maternal depletion occurred despite a mean birth interval of three years. Average maternal weight gain during pregnancy was about 5 kg, thus the estimated weight gain from fat deposition, blood and extracellular volume expansion was only 650 g. Evidence of increasing fertility in recent years highlights the need for effective family planning to limit the impact on women of child-bearing age.
在巴布亚新几内亚的沃塞拉地区，899名育龄妇女的营养状况（通过体重、体重指数和皮褶厚度衡量）与胎次呈显著负相关，与年龄无关。尽管平均生育间隔为三年，但仍出现了母体营养消耗的情况。孕期母体平均体重增加约5千克，因此，从脂肪沉积、血液和细胞外液量增加所估计的体重增加仅为650克。近年来生育力上升的证据凸显了有效计划生育的必要性，以限制对育龄妇女的影响。
