Prepregnancy Dietary Patterns Are Associated with Blood Lipid Level Changes During Pregnancy: A Prospective Cohort Study in Rio de Janeiro, Brazil - 14/12/17
Abstract |
Background |
Physiologic adaptations lead to an increase in blood lipid levels during pregnancy, yet little is known about the influence of prepregnancy dietary patterns.
Aim |
To identify whether prepregnancy dietary patterns that explain the consumption of fiber, energy, and saturated fat are associated with blood lipid levels throughout pregnancy.
Design |
Prospective cohort study, with data collection at gestational weeks 5 to 13, 20 to 26, and 30 to 36. A food frequency questionnaire was administered at baseline (gestational week 5 to 13).
Participants/setting |
Women with singleton pregnancy (N=299) aged 20 to 40 years, without infectious/chronic disease (except obesity) were enrolled in the study. One hundred ninety-nine women were included in the final analysis. The study took place at a prenatal service of a public health care center in Rio de Janeiro, Brazil, during the period from 2009 to 2012.
Main outcome measures |
Total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol, and triglyceride levels, measured at all trimesters.
Statistical analyses performed |
Dietary patterns were derived by reduced rank regression. Fiber density, dietary energy density, and percent energy from saturated fat were response variables. Crude and adjusted longitudinal linear mixed-effects regression models were performed to account for confounders and mediators. Interaction terms between dietary pattern and gestational week were tested.
Results |
Fast Food and Candies; Vegetables and Dairy; and Beans, Bread, and Fat patterns were derived. Our Fast Food and Candies pattern was positively associated with triglyceride level (β=4.961, 95% CI 0.945 to 8.977; P=0.015). In the HDL-C rate of change prediction, significant interactions were observed between both the Fast Food and Candies and Vegetables and Dairy patterns and gestational week (β=–.053, 95% CI –0.101 to –0.004; P=0.035 and β=.055, 95% CI –0.002 to 0.112; P=0.060, respectively). The Beans, Bread, and Fat pattern was not associated with blood lipid levels.
Conclusions |
Prepregnancy dietary patterns were associated with gestational blood lipid levels; that is, higher scores for the Fast Food and Candies pattern were associated with higher triglyceride and slower HDL-C rates of change during pregnancy, whereas higher scores for the Vegetables and Dairy dietary patterns were associated with faster HDL-C rates of change over gestational weeks.
