“…It is clear that a large proportion of the women currently giving birth know about the value of breast-feeding and intend to nurse their babies. The present study indicates that intentions regarding duration are modest, especially in view of recommendations to breast-feed for 6 months and longer (Barness, 1981;Fomon et ah, 1979) and the fact that it is health-promoting for the infant (Ahn & MacLean, 1980) and that it is possible for the mother (Hartmann et al, 1981).…”

SummaryTo determine patterns of infant feeding and influencing factors, 131 women, interested in breast-feeding and giving birth in one hospital in British Columbia, Canada, were followed for 6 months post-partum. Data were collected from hospital records and each participant completed mail-in questionnaires when their babies were 1, 3 and 6 months old. At 6 months 3·9% were exclusively breast-feeding, 26·5% were feeding their infants breast-milk and semi-solids and 26·5% were combining breast-feeding with formula and/or semi-solids. Over 50% discontinued breast-feeding before their stated intentions. Most women had chosen to breast-feed because of benefits to the baby, and most gave up breastfeeding because of perceived insufficient milk.

“…A small‐scale, prospective study undertaken in a semi nomadic pastoral population in northern Tanzania showed that mothers often stated an intention to introduce adult staple foods and terminate breastfeeding at the end of the long rains (22). A study in Western Australia showed that seasonal conditions could have a significant effect in the level of milk production but the reasons were not fully understood (23). Because of the geographical location, Xinjiang has four very different seasons.…”

“…On the one hand, raising twins to maturity requires more maternal investment (e.g. the production of around twice as much milk during the first 9 months of lactation 44 ), which may extend the duration of lactational amenorrhoea and delay the next reproduction. On the other hand, the higher mortality of twin offspring 1 , 5 , 7 , 16 – 18 , 45 may lead to shorter interbirth intervals.…”

Mothers with higher twinning propensity had lower fertility in pre-industrial Europe

et al. 2022

Historically, mothers producing twins gave birth, on average, more often than non-twinners. This observation has been interpreted as twinners having higher intrinsic fertility – a tendency to conceive easily irrespective of age and other factors – which has shaped both hypotheses about why twinning persists and varies across populations, and the design of medical studies on female fertility. Here we show in >20k pre-industrial European mothers that this interpretation results from an ecological fallacy: twinners had more births not due to higher intrinsic fertility, but because mothers that gave birth more accumulated more opportunities to produce twins. Controlling for variation in the exposure to the risk of twinning reveals that mothers with higher twinning propensity – a physiological predisposition to producing twins – had fewer births, and when twin mortality was high, fewer offspring reaching adulthood. Twinning rates may thus be driven by variation in its mortality costs, rather than variation in intrinsic fertility.
