Typical pregnancy is now 39 weeks – Omega-3 and Vitamin D might restore it to full 40 weeks

In recent decades many things have happened

  • Vitamin D levels have decreased 35 reasons
  • Omega-3 levels have decreased
  • Omega-6 levels (which block Omega-3) have increased

Typical Pregnancy Now 39 Weeks, Not 40

  • WebMD – March of Dimes 2006
    “The most common length of a pregnancy in the U.S. is a week shorter than it was just over a decade ago, dropping from 40 weeks to 39 weeks, according to a new analysis from the March of Dimes”
    Possible reasons postulated includes better fetal monitoring, obesity, and maternal age
    No mention of increased Omega-6 which blocks Omega-3

Omega-3 restores pregnancy of pregnancy – perhaps even add before gestation – Sept 2016

A balance of omega-3 and omega-6 polyunsaturated fatty acids is important in pregnancy

Highlights

  • N-3 PUFA improves maternal and neonatal health, and increases gestation length.
  • N-3 PUFA inhibits pro-inflammatory cytokines that are vital at early and late gestation.
  • Cytokine profile in the uterus during pregnancy may affect pregnancy establishment and outcomes.
  • Effects of n-3 PUFA on different stages of pregnancy needs to be established.

Emerging evidence suggests that omega (n)-3 PUFA and their metabolites improve maternal and neonatal health outcomes by modifying gestation length, and reducing the recurrence of pre-term delivery. N-3 PUFA has been associated with prolonged gestation and increased birth dimensions such as birth weight and head circumference. However, mothers giving birth to larger babies are at an increased risk of having dysfunctional labour, genital tract laceration, and delivery via caesarean section. Likewise, high infant weight at birth has been linked to several metabolic and cardiovascular disorders in the offspring. Prolonged gestation also leads to reduced placental function which has been implicated in fetal distress, and perinatal death. Till date, the mechanism through which high n-3 PUFA intake during pregnancy increases gestation length and birth weight is vaguely understood. Early and later stages of pregnancy is characterised by increased production of pro-inflammatory cytokines which are required for pregnancy establishment and labour regulation respectively. Conversely, mid-stage of pregnancy requires anti-inflammatory cytokines necessary for uterine quiescence, pregnancy maintenance and optimal fetal growth. Apparently, changes in the profiles of local cytokines in the uterus during different stages of pregnancy have a profound effect on pregnancy progression. This review focuses on the intake of n-3 and n-6 PUFA during pregnancy and the impact it has on gestation length and infant weight at birth, with a particular emphasis on the expression of inflammatory cytokines required for timely pregnancy establishment (embryo reception and implantation) and labour induction. It is concluded that an appropriate dose of n-3 and n-6 PUFA needs to be established during different stages of pregnancy.

Women supplemented with high n-3 PUFA had their gestation
length extended by 6 days [34] and 8.3 days longer in high risk pregnancies [35]

Of keen interest in the intervention studies is the observation
that n-3 PUFA treatment were generally administered after the
pregnancy had been established (Table 2). Data from observational
studies, where mothers consumed high amount of n-3 PUFA prior to conception,
revealed a significantly higher infant weight at birth.
Corrected average birth weight among Faroese woman was
3610 ± 603 g, and the frequency of having new born infants heavier
than 4.5 kg was 3 (three) times higher than Denmark where n-3
PUFA consumption was very low [73]. It can therefore be argued
that n-3 PUFA supplementation at the early stage of pregnancy may
have a significant influence on gestation length and other pregnancy outcomes;
perhaps by regulating pregnancy establishment activities, leading to gestation
length prolongation and consequently high infant weight at birth.
