Adherence to Canada's Food Guide Recommendations during Pregnancy:Nutritional Epidemiology and Public Health

Background: In Canada, pregnant women are typically referred to Canada's Food Guide (CFG), a set of national dietary recommendations designed to promote adequate nutrient intake. Pregnant women are also advised to gain weight within the Institute of Medicine guidelines, which differ by prepregnancy body mass index (BMI). However, CFG recommendations do not account for prepregnancy BMI and provide no guidance on "less healthy" (LH) foods. Objective: The aim of this study was to score women's diets according to adherence to CFG recommendations and consumption of LH foods and to examine differences between these diet scores by prepregnancy BMI. Methods: Participants enrolled in the APrON (Alberta Pregnancy Outcomes and Nutrition) prospective cohort study completed a 24-h recall in their second trimester (n = 1630). A score was created on the basis of each daily dietary CFG recommendation met, ranging from 0 to 9. The distribution of consumption (grams per day) of 8 LH food groups was given a score of 0 (none) or 1, 2, or 3 (representing the lowest, middle, or highest tertiles, respectively) and summed giving a total LH score of 0-24. Results: There were few differences in CFG recommendations met by prepregnancy BMI status, although fewer women who were overweight or obese prepregnancy met the specific recommendation to consume 7-8 servings of fruit or vegetables/d than did those who were under- or normal weight (47% and 41% compared with 50% and 54%, respectively). Although differences were small, women who were obese prepregnancy had lower CFG scores (β = -0.28; 95% CI:-0.53, -0.02) and higher LH scores (β = 0.45; 95% CI: 0.04, 0.86) than did those who were normal weight. Conclusion: The study results suggest that more attention may need to be paid to individualized counseling on dietary recommendations that take account of prepregnancy BMI

Point of Care (POC) Influenza Immunization for Pregnant Women, Calgary Zone, Alberta Health Services

Introduction Vaccinating pregnant patients for neonatal protection needs to be integrated into prenatal care as new vaccines emerge. Uptake of influenza vaccine, universally recommended in pregnancy, is low. Immunization was offered and administered to pregnant women at point of care (POC) during two flu seasons at an urban tertiary care center. Objectives and Approach Primary objective is to determine if POC impacts immunization rate during flu season among a cohort of pregnant women by location and gestational age. Secondary objectives are to examine the pattern of influenza-like illnesses (ILI) among vaccinated and unvaccinated women, and to describe pilot outcomes of POC. Four consecutive influenza seasons (2014/2015, 2015/2016, 2016/2017, 2017/2018) will be examined using seven databases: a) Clinibase, b) National Ambulatory Care Reporting System; C) Discharge Abstract Database; d) Physician Claims; e) Alberta Perinatal Health Program; f) Calgary Zone Public Health; and g) Pharmaceutical Information Network. Outcomes will be examined descriptively using frequencies and proportions. Results Based on the preliminary analysis, approximately 10, 000 visits among 2,500 women occurred during each flu season at the four obstetric care locations: two outpatient clinics and two inpatient units. The proportion of pregnant women who received the flu vaccine ranged from 15-21% during the first three flu seasons. Majority of the women received the vaccine at the flu campaigns (range 48-67%), followed by pharmacy (20-32%). For the 2017-2018 season, year to date uptake rates in outpatient clinics are significantly higher. Final results on additional outcomes will be available by September 2018. Conclusion/Implications In completing this study, we hope to better understand the patterns of immunization uptake in pregnancy by place of immunization and gestational age, i.e. identifying optimal “window of opportunity”. Results will inform the infrastructure needed to collect data on vaccines administered during pregnancy and linkage to maternal and infant outcomes

Age-period-cohort effects in pre-existing and pregnancy-associated diseases amongst primiparous women

Abstract Background The average age at first birth is steadily increasing in developed countries; however, demographic shifts in maternal age at childbearing have not occurred in isolation. While temporal increases in adverse pregnancy outcomes are typically attributed to increases in maternal age, little is known about how maternal health status has changed across maternal age, period of delivery, and birth cohort. Methods Natality files were used to identify primiparous women delivering liveborn, singleton infants in the USA in 1989, 1994, 1999, 2004, 2009, and 2014 (n = 6,857,185). Age-period-cohort models using the intrinsic estimator adjusted for temporal trends in smoking and gestational weight gain were used to quantify temporal changes in the rates of pre-existing (chronic hypertension, pre-existing diabetes) and pregnancy-associated (pregnancy-associated hypertension, gestational diabetes, eclampsia) diseases. Log-linear models were used to model the impact of temporal changes on preterm birth, small, and large for gestational age (SGA/LGA) births. Results Significant period effects resulted in temporal increases in the rate of chronic hypertension, pregnancy-associated hypertension, and gestational diabetes, and a significant decrease in the rate of eclampsia. These observed period effects were associated with a 10.6% increase in the rate of SGA and a 7.1% decrease in LGA. Had the rate of pre-existing and pregnancy-associated diseases remained static over this time period, the rate of preterm birth would have increased by 5.9%, but instead only increased by 4.4%. Conclusions Independent of changes in the incidence of pre-existing and pregnancy-associated diseases as women age, the obstetric population is becoming less healthy over time. This is important, as these changes have a direct negative impact on short-term obstetric outcomes and women’s long-term health

Understanding the self-management experiences and support needs during pregnancy among women with pre-existing diabetes: a qualitative descriptive study

Abstract Background With the increasing prevalence of pre-existing type 1 and type 2 diabetes in pregnancy and their associated perinatal risks, there is a need to focus on interventions to achieve optimal maternal glycemia to improve pregnancy outcomes. One strategy focuses on improving diabetes self-management education and support for expectant mothers with diabetes. This study’s objective is to describe the experience of managing diabetes during pregnancy and identify the diabetes self-management education and support needs during pregnancy among women with type 1 and type 2 diabetes. Methods Using a qualitative descriptive study design, we conducted semi-structured interviews with 12 women with pre-existing type 1 or 2 diabetes in pregnancy (type 1 diabetes, n = 6; type 2 diabetes, n = 6). We employed conventional content analyses to derive codes and categories directly from the data. Results Four themes were identified that related to the experiences of managing pre-existing diabetes in pregnancy; four others were related to the self-management support needs in this population. Women with diabetes described their experiences of pregnancy as terrifying, isolating, mentally exhausting and accompanied by a loss of control. Self-management support needs reported included healthcare that is individualized, inclusive of mental health support and support from peers and the healthcare team. Conclusions Women with diabetes in pregnancy experience feelings of fear, isolation and a loss of control, which may be improved through personalized management protocols that avoid “painting everybody with the same brush” as well as peer support. Further examination of these simple interventions may yield important impacts on women’s experience and sense of connection

Examining Diabetes Distress in Pre-existing Diabetes in Pregnancy: Protocol for an Explanatory Sequential Mixed Methods Study

Diabetes distress has been shown to be highly prevalent in adults living with type 1 and type 2 diabetes with important implications for glycemic control, self-care, and self-management behaviors. Despite considerable focus on self-management and glycemic targets during pregnancy, current literature lacks information on diabetes distress in pregnancy, particularly in women with type 2 diabetes. This article outlines an explanatory sequential mixed methods research protocol to examine diabetes distress during pregnancy in women with pre-existing diabetes. The aims of the study were to: (1) establish the prevalence and correlates of diabetes distress in women attending a diabetes and pregnancy clinic; (2) use this quantitative data to inform development of an interview guide and plan for sampling for telephone interviews; and (3) explore and describe the experiences of diabetes distress during pregnancy. The quantitative strand was a cross-sectional survey of 76 women using self-reported questionnaires to collect demographic and clinical data, and validated tools to assess health variables, including the outcome of interest of diabetes distress using the Problem Area in Diabetes scale. The qualitative strand applied interpretive description methodology to explore the quantitative results using semi-structured qualitative interviews with 18 women to obtain patient perspectives of diabetes distress and experiences of managing diabetes in pregnancy. The explanatory sequential mixed methods research will provide an opportunity to add contextual qualitative experiences from women with pre-existing diabetes during pregnancy to provide a comprehensive picture of diabetes distress. The results will inform further research priorities that protect and promote mental health, psychosocial well-being, and self-management practices for this population

Management of Pregnancy-Associated Thrombotic Thrombocytopenia Purpura

Abstract Thrombotic thrombocytopenia purpura (TTP) is an infrequent but serious disease. Pregnancy is a known risk factor for presentation or relapse of TTP. Difficulties in differentiating TTP from preeclampsia/HELLP (hemolysis, elevated liver enzymes and low platelets) syndrome, and current treatment recommendations are discussed in this case report. A woman with previously treated and stable TTP had a relapse at 36 weeks' gestation. Careful surveillance led to an early diagnosis. Severe disease in the peripartum period was treated successfully with cryosupernatant plasma-based plasmapheresis and platelet transfusion, with good maternal and neonatal outcomes. Cryosupernatant plasma is a viable alternative to fresh frozen plasma for plasmapheresis for TTP and may offer some therapeutic and logistical advantages. Platelet transfusion can be undertaken safely if needed to prevent or treat significant hemorrhage

Development and Preliminary Validation of a Comprehensive Questionnaire to Assess Women’s Knowledge and Perception of the Current Weight Gain Guidelines during Pregnancy

The aim of this study was to develop and validate an electronic questionnaire, the Electronic Maternal Health Survey (EMat Health Survey), related to women’s knowledge and perceptions of the current gestational weight gain guidelines (GWG), as well as pregnancy-related health behaviours. Constructs addressed within the questionnaire include self-efficacy, locus of control, perceived barriers, and facilitators of physical activity and diet, outcome expectations, social environment and health practices. Content validity was examined using an expert panel (n = 7) and pilot testing items in a small sample (n = 5) of pregnant women and recent mothers (target population). Test re-test reliability was assessed among a sample (n = 71) of the target population. Reliability scores were calculated for all constructs (r and intra-class correlation coefficients (ICC)), those with a score of >0.5 were considered acceptable. The content validity of the questionnaire reflects the degree to which all relevant components of excessive GWG risk in women are included. Strong test-retest reliability was found in the current study, indicating that responses to the questionnaire were reliable in this population. The EMat Health Survey adds to the growing body of literature on maternal health and gestational weight gain by providing the first comprehensive questionnaire that can be self-administered and remotely accessed. The questionnaire can be completed in 15–25 min and collects useful data on various social determinants of health and GWG as well as associated health behaviours. This online tool may assist researchers by providing them with a platform to collect useful information in developing and tailoring interventions to better support women in achieving recommended weight gain targets in pregnancy

Risks of Dysglycemia Over the First 4 Years After a Hypertensive Disorder of Pregnancy

Women with the hypertensive disorders of pregnancy (HDP) (preeclampsia [PE] and gestational hypertension [GHTN]) have increased risks of future diabetes. Postpartum glycemic testing offers early identification and treatment of dysglycemia, but evidence-based recommendations for this high-risk population are lacking. The objective of this study was to describe the risks of developing dysglycemia in women with normotensive and hypertensive pregnancies over the first 4 years postpartum
