By Dr. Priyom Bose, Ph.D.May 8 2023Reviewed by Benedette Cuffari, M.Sc. Despite extensive research on the subject, preterm birth remains inadequately understood and a significant public health problem in the United States.
Background Environmental exposures and GP diet are two factors that may act both independently and as modifiers of adverse birth outcomes. In relation to environmental exposures, ambient pollutants stemming from fossil fuel combustion are particularly relevant. Various GP dietary patterns have been investigated in relation to PTB, both before conception and during pregnancy. This literature suggests that certain diets, such as those high in red meat and white bread intake, entail a higher risk of PTB, while others, such as the Mediterranean diet, are associated with decreased risk of PTB.
The percentages of energy intake from saturated and total fats and total energy intake were dichotomized at the 75th percentile. Log binomial regressions were used to estimate risk ratios for PTB by pollutant interquartile ranges. The dietary characteristics of GPs who experienced PTB and those who did not were reasonably balanced with respect to the daily energetic percent of total and saturated fats. Daily caloric intake was slightly different between term and preterm birth, with a difference between means being about 195 kcals. This imbalance was observed even after dichotomizing at the 75th percentile.
PM2.5 might be inversely associated with PTB when considered with total and saturated fats in the second trimester. Imprecise ICRs reflected a departure from additivity with some pollutant-diet combinations.
