“…Estimating GA by using the last normal menstrual period of the mother may be subject to considerable error, especially because of recall bias, bleeding after conception interpreted as normal menstruation, irregular menstrual cycles, or late ovulation (75,76). Contrary to GA, birth weight measurement is usually better reported in medical records (77).…”

Seafood consumption during pregnancy carries both benefits (high n-3 FA intake) and risks (exposure to environmental contaminants) for the developing fetus. We determined the impacts of marine n-3 FA and environmental contaminants on gestational age (GA) of Nunavik women and the anthropometric characteristics of their newborns. FA and contaminant (polychlorinated biphenyls and mercury) concentrations were measured in cord plasma of Nunavik newborns (n = 454) and compared with those of a group of newborns (n = 29) from southern Québec. Data were collected from hospital records and birth certificates. In Nunavik newborns, arachidonic acid (AA) was two times lower (P < 0.0001), whereas DHA concentration, the sigman-3 / sigman-6 ratio, and the percentage of n-3 highly unsaturated FA (HUFA) (of the total HUFA) were three times higher (P < 0.0001) compared with southern Québec newborns. After controlling for confounders, GA and birth weight were higher by 5.4 d [95% confidence interval (CI): 0.7-10.1] and 77 g (95% CI: -64 to 217) in the third tertile of percentage of n-3 HUFA (of the total HUFA) as compared with the first tertile. There was no evidence that contaminants had negative effects on GA or birth weight. In this seafood-eating population, an increase in the proportion of n-3 HUFA (of the total HUFA), measured in umbilical cord plasma phospholipids, was associated with a significantly longer GA.

“…T reloar, Behn and Cowan [2] have presented factual evidence that gestational interval is increased in some cases well beyond the true period of gestation by preceding abortions, often not recognized, as well as by preceding births, no menstruation having intervened. Shorten ing of the gestational interval occurs, again in unknown proportions o f cases, through occurrence o f post-pregnancy cyclic bleedings in rhythm with prior menstruations.…”

“…The term "gestational age" is unsatisfactory in that it is used by some for the interval since the last menstrual period (Treloar et al, 1967), by others for age since fertilization or an event closely related thereto (Jirasek, 1971), and by still others for the interval since implantation (Hjortsjo, 1960).…”
