Preconceptional diet quality is associated with Birth Outcomes among low socioeconomic status minority women in a high-income country
European Journal of Nutrition, 2020Co-Authors: Kathleen Abu-saad, Vered Kaufman-shriqui, Laurence S. Freedman, Ilana Belmaker, Drora FraserAbstract:Purpose Studies of the association between maternal nutrition and Birth Outcomes have investigated differing nutrients, maternal socioeconomic conditions, and timing within the reproductive cycle; and have produced inconsistent results. We evaluated the association of preconceptional maternal dietary intake with Birth Outcomes among low socioeconomic status ethnic minority women in a high-income country. Methods In this prospective cohort study, habitual preconceptional dietary intake was assessed among pregnant Bedouin Arab women in Israel ( n = 384), using a short culturally specific, targeted food frequency questionnaire. Multiple nutrients (protein, lysine, calcium, iron, zinc, folate, omega-3 fatty acids) were evaluated simultaneously via a diet quality score derived from principal component analysis. Multivariable logistic regression was used to test associations between the diet quality score and a composite adverse Birth Outcomes variable, including preterm Birth, low Birth weight and small for gestational age. Results Sixty-nine women (18%) had adverse Birth Outcomes. Women with low preconceptional diet quality scores had low intakes of nutrient-rich plant foods, bioavailable micronutrients, and complete proteins. In multivariable analysis, a woman at the 10th percentile of the diet quality score had a 2.97 higher odds (95% CI 1.28–6.86) of an adverse Birth outcome than a woman at the 90th percentile. Conclusion Low diet quality during the preconceptional period was associated with adverse Birth Outcomes among low socioeconomic status minority women in a high-income country. The results have implications for the development of appropriate intervention strategies to prevent adverse Birth Outcomes, and the promotion of adequate nutrition throughout the child-bearing years.

maternal nutrition and Birth Outcomes
Epidemiologic Reviews, 2010Co-Authors: Kathleen Abusaad, Drora FraserAbstract:In this review, the authors summarize current knowledge on material nutritional requirements during pregnancy, with a focus on the nutrients that have been most comonly investigated in association with Birth Outcomes. Data sourcing and extractiion included searches of the primary resources establishing maternal nutrient requirements during pregnancy (e.g., Dietary Reference Intakes), and searches of Medline for "maternal nutrition"/ (specific nutrient of interest) and "Birth/pregnancy Outcomes," focusing mainly on the less extensively reviewed evidence from observational studies of maternal dietary intake and Birth Outcomes. The authors used a conceptual framework which took both primary and secondary factors (e.g., baseline maternal nutritional variables) into account when interpreting study findings. The authors conclude that maternal nutrition is a modifiable risk factor of public health importance that can be integrated into efforts to prevent adverse Birth Outcomes, particularly among economically developing/low-income populations.

psychosocial stress during pregnancy is related to adverse Birth Outcomes results from a large multi ethnic community based Birth cohort
European Journal of Public Health, 2013Co-Authors: Eva M Loomans, Aimee E Van Dijk, Tanja G M Vrijkotte, Manon Van Eijsden, Karien Stronks, Bea Van Den Bergh, Reinoud J B J GemkeAbstract:Background: Prevalence rates of psychosocial stress during pregnancy are substantial. Evidence for associations between psychosocial stress and Birth Outcomes is inconsistent. This study aims to identify and characterize different clusters of pregnant women, each with a distinct pattern of psychosocial stress, and investigate whether Birth Outcomes differ between these clusters. Methods: Latent class analysis was performed on data of 7740 pregnant women (Amsterdam Born Children and their Development study). Included constructs were depressive symptoms, state anxiety, job strain, pregnancy-related anxiety and parenting stress. Results: Five clusters of women with distinct patterns of psychosocial stress were objectively identified. Babies born from women in the cluster characterized as ‘high depression and high anxiety, moderate job strain’ (12%) had a lower Birth weight, and those in the ‘high depression and high anxiety, not employed’ cluster (15%) had an increased risk of pre-term Birth. Conclusions: Babies from pregnant women reporting both high levels of anxiety and depressive symptoms are at highest risk for adverse Birth Outcomes.

pregnancy specific stress prenatal health behaviors and Birth Outcomes
Health Psychology, 2008Co-Authors: Marci Lobel, Dolores Cannella, Jennifer E Graham, Carla J Devincent, Jayne Schneider, Bruce A MeyerAbstract:Objective: Stress in pregnancy predicts earlier Birth and lower Birth weight. The authors investigated whether pregnancy-specific stress contributes uniquely to Birth Outcomes compared with general stress, and whether prenatal health behaviors explain this association. Design: Three structured prenatal interviews (N 279) assessing state anxiety, perceived stress, life events, pregnancy-specific stress, and health behaviors. Main Outcome Measures: Gestational age at delivery, Birth weight, preterm delivery (37 weeks), and low Birth weight (2,500 g). Results: A latent pregnancy-specific stress factor predicted Birth Outcomes better than latent factors representing state anxiety, perceived stress, or life event stress, and than a latent factor constructed from all stress measures. Controlling for obstetric risk, pregnancy-specific stress was associated with smoking, caffeine consumption, and unhealthy eating, and inversely associated with healthy eating, vitamin use, exercise, and gestational age at delivery. Cigarette smoking predicted lower Birth weight. Clinically-defined Birth Outcomes were predicted by cigarette smoking and pregnancy-specific stress. Conclusion: Pregnancy-specific stress contributed directly to preterm delivery and indirectly to low Birth weight through its association with smoking. Pregnancyspecific stress may be a more powerful contributor to Birth Outcomes than general stress.

Conceptualizations, measurement, and effects of prenatal maternal stress on Birth Outcomes
Journal of Behavioral Medicine, 1994Co-Authors: Marci LobelAbstract:This article analyzes the conceptual and methodological approaches which have been used to investigate effects of prenatal maternal stress on Birth Outcomes and highlights the major findings of this research. By viewing the most widely used operational definitions of prenatal stress in a broader theoretical framework, it can be seen that most studies have failed to conceptualize stress reliably. This, in addition to common methodological and design flaws which are described in the article, has produced equivocal findings about the role of stress in adverse Birth Outcomes such as preterm delivery and low Birth weight. Recent studies using more powerful, multidimensional approaches to stress definition and measurement provide more definitive evidence and suggest some precise effects. Implications and strategies for future research are presented.

Vitamin D and Pregnancy: Skeletal Effects, Nonskeletal Effects, and Birth Outcomes
Calcified Tissue International, 2013Co-Authors: Bruce W. Hollis, Carol L. WagnerAbstract:The function and requirement of vitamin D during pregnancy for both mother and fetus have remained a mystery. This fact was highlighted by The Cochrane Review in 2000, which reported a lack of randomized controlled trials (RCTs) with respect to vitamin D requirements during pregnancy. Unfortunately, during the past decade only a single RCT has been performed with respect to vitamin D requirements during pregnancy. In this review we will discuss vitamin D metabolism during pregnancy as well as the consequences of vitamin D deficiency on skeletal, nonskeletal, and Birth Outcomes using Birth observational data and data from our recent RCT. New RCT data strongly support previous observational studies in that improving nutritional vitamin D status will improve Birth Outcomes. The new RCT data indicate that 4,000 IU/day vitamin D_3 during pregnancy will “normalize” vitamin D metabolism and improve Birth Outcomes including primary cesarean section and comorbidities of pregnancy with no risk of side effects.
