How to improve health literacy to reduce short- and long-term consequences of maternal obesity?

Healthy Lifestyle in the First 1000 Days and Overweight and Obesity Throughout Childhood

OBJECTIVES

Investigate associations of different family healthy lifestyle scores (HLS) during the first 1000 days with childhood overweight and obesity (OWOB).

METHODS

Cohort-specific analyses were conducted on participants (n = 25 006) from 4 European birth cohorts (The study on the pre- and early postnatal determinants of child health and development [EDEN], Elfe, France; Generation R, the Netherlands; and Lifeways, Ireland). Three composite HLSs were calculated: a maternal pregnancy HLS based on prepregnancy body mass index (BMI) and diet quality, physical activity, smoking status, and alcohol consumption during pregnancy; a parental pregnancy HLS additionally considering paternal BMI and smoking status; and an infancy HLS based on breastfeeding duration, age of solid food introduction, and exposure to passive smoking. Associations with child BMI (primary outcome) and waist-to-height ratio (WHtR, available in 2 cohorts) in early (5-5.5 years), middle (7-8 years), and late childhood (9-12 years) were assessed using linear (BMI and WHtR z-scores) and robust Poisson (International Obesity Task Force [IOTF] categories) regression analyses adjusted for sociodemographic confounders.

RESULTS

Only a small proportion of families had favorable lifestyle factors during pregnancy and early infancy, with 3.4% to 10.0%, 1.9% to 3.7%, and 12.2% to 23.6% scoring maximum for maternal, parental, and infancy HLS, respectively. Associations between higher HLSs and a lower risk of OWOB when measured by BMI z-scores or IOTF categories were found for maternal HLS and early (3/4 cohorts with available data), middle (1/2), and late childhood (2/4); parental HLS and early (3/4), middle (2/2), and late childhood (4/4). Associations between infancy HLS and childhood OWOB were less consistent and did not remain significant after additional adjustment for parental HLS. Associations with WHtR were solely significant in EDEN at 5.5 years.

CONCLUSIONS

Greater maternal and parental adherence to healthy lifestyle behaviors during pregnancy was associated with a lower risk of offspring OWOB throughout childhood, illustrating the importance of promoting healthy lifestyle behaviors at the family level during pregnancy.

Impact of maternal body mass index and gestational weight gain on maternal and neonatal outcomes in twin pregnancies

INTRODUCTION

To date, there have only been provisional recommendations about the appropriate gestational weight gain in twin pregnancies. This study aimed to contribute evidence to this gap of knowledge.

MATERIAL AND METHODS

Using a cohort of 10 603 twin pregnancies delivered between 2000 and 2015 in the state of Hessen, Germany, the individual and combined impact of maternal body mass index and gestational weight gain on maternal and neonatal outcomes was analyzed using uni- and multivariable logistic regression models. The analysis used newly defined population-based quartiles of gestational weight gain in women carrying twin pregnancies (Q1: <419.4 g/week [low weight gain], Q2-Q3: 419.4-692.3 g/week [optimal weight gain], Q4: >692.3 g/week [high weight gain]) and the World Health Organization body mass index classification.

RESULTS

Pre-pregnancy body mass index ≥25 kg/m² was associated with significantly increased rates of cesarean deliveries (aOR1.2, 95% CI: 1.01-1.41) and pregnancy-induced hypertensive disorders (aOR 1.53, 95% CI: 1.11-2.1) but not with any adverse neonatal outcome. Perinatal mortality (aOR 2.23, 95% CI: 1.38-3.6), preterm birth (aOR 1.88, 95% CI: 1.58-2.25), APGAR'5 < 7 (aOR 1.61, 95% CI: 1.19-2.17) and admissions to the neonatal intensive care unit (aOR 1.6, CI: 1.38-1.85) were increased among women with low gestational weight gain. Rates of cesarean deliveries were high in both women with low (aOR 1.25, 95% CI: 1.05-1.48) and high gestational weight gain (aOR 1.17, 95% CI: 1.01-1.35). A high gestational weight gain was also associated with higher rates of hypertensive disorders in pregnancy (aOR 2.32, 95% CI: 1.79-3.02) and postpartum hemorrhage (aOR 1.72, 95%CI: 1.12-2.63). The risk of preterm birth, low Apgar scores and NICU admissions showed a converse linear relation with pre-pregnancy body mass index in women with low gestational weight gain.

CONCLUSIONS

In twin pregnancies, nonoptimal weekly maternal weight gain seems to be strongly associated with maternal and neonatal adverse outcomes. Since gestational weight gain is a modifiable risk factor, health care providers have the opportunity to counsel pregnant women with twins and target their care accordingly. Additional research to confirm the validity and generalizability of our findings in different populations is warranted.

Health literacy and related behaviour among pregnant women with obesity: a qualitative interpretive description study

Background

Obesity in pregnant women is increasing worldwide, affecting the health of both mother and baby. Obesity may be associated with inadequate health literacy, a central competence when navigating antenatal health information and services. This study explores women’s health literacy by examining their knowledge, motivation and skills to access, understand and evaluate health information and the related behaviour among a sample of pregnant women with a prepregnant body mass index (BMI) > 25 kg/m².

Methods

An inductive, qualitative study using an interpretive description methodology. Data was collected through ten semi-structured interviews with pregnant women with a prepregnancy BMI > 25 kg/m² attending antenatal care at the midwifery clinic at Aarhus University Hospital in the Central Denmark Region.

Results

Pregnant women with obesity understand general health information provided by health professionals, but translating this knowledge into specific healthy behaviours presents a challenge. Although difficulties navigating booking systems and available digital services contribute to this problem, apps can help facilitate navigation. However, successful navigation may depend on adequate e-health literacy. Conflicting information from health professionals, social media and families also present a challenge for pregnant women, requiring a broad skillset for critical evaluation and resolution.

Conclusions

Adequate health literacy is necessary for pregnant women receiving antenatal care to (i) translate general health information into personalised healthy behaviour, (ii) access and navigate complex and digitalised systems, and (iii) critically evaluate conflicting information. Person-centred differentiation in the organisation of antenatal care may benefit vulnerable pregnant women with inadequate health literacy.

Association Between Maternal Body Mass and Physical Activity Counseling During Pregnancy

Aims: The antenatal period provides an important opportunity for giving advice on healthy lifestyle choices. However, the prevalence of maternal obesity is increasing, and women report that they do not receive counseling. We investigated the information given to pregnant women on gestational weight gain, physical activity, and nutrition during pregnancy in relation with their initial weight status, current gestational weight gain and diagnoses of either pre-pregnancy overweight/obesity or excessive gestational weight gain. Methods: Cross-sectional survey using a questionnaire. Pregnant participants (n = 141) were recruited from a midwife center. They completed a structured questionnaire on the information they received during their pregnancy and we assessed its relationship with their weight. Results: We found that many pregnant women did not receive advice about physical activity, gestational weight gain and nutrition (37.5, 53.2, and 66.2%, respectively). Women with weight problems (pre-pregnancy overweight/obesity and excessive gestational weight gain) were less targeted for counseling, although more than 80% of the women viewed receiving information on these topics as positive. Also, being informed of a weight problem was associated with a greater chance of receiving information about physical activity, gestational weight gain and nutrition (all p < 0.05). However, verbalization of the weight problems was low (14.0% of women with pre-pregnancy overweight were informed of their status). Conclusion: Health professionals should dispense more information, especially on PA and particularly for women with weight problems. Verbalization of the weight problem seems associated with more frequent transmission of information.

Changes in Maternal Body Mass Index, Weight Gain and Outcome of Singleton Pregnancies from 2000 to 2015: A Population-based Retrospective Cohort Study in Hesse/Germany

Introduction Maternal obesity and excessive gestational weight gain (GWG) affect the outcomes of women and their offspring. Our aim was to evaluate population-based data from Germany.

Material and Methods Data from 583 633/791 514 mother-child pairs obtained from the perinatal database in Hesse for the period from 2000 to 2015 were used after excluding incomplete or non-plausible datasets. Early-stage pregnancy maternal body mass index (BMI) and GWG were evaluated. Significant outcome changes were calculated using linear or logistic regression models.

Results The mean maternal age increased from 29.9 to 31.28 years; GWG increased from 445.1 to 457.2 g/week (p < 0.01). Similarly, rates for both overweight and obesity rose from 31.5 to 37.5% (p < 0.001). Cesarean section rates rose from 22.8 to 33.2% (p < 0.001) and rates of postpartum hemorrhage increased from 0.6 to 1% (p < 0.001). There was no significant change in the rates for stillbirth or perinatal mortality (p = 0.92 and p = 0.53 respectively), but there was an increase in the rates of admissions to neonatal intensive care units from 7.8 to 9.5% (p < 0.0001). The percentage of newborns with an Apgar score of < 7 at 5 minutes increased from 1 to 1.1% (p < 0.01) and the rate of neonates with an umbilical artery pH of < 7.1 rose from 1.7 to 2.4% (p < 0.01).

Conclusions In just 15 years, pre-pregnancy BMI and GWG rates of women with singleton pregnancies have increased, and this increase has been accompanied by a significant rise in the rate of cesarean sections and a significant worsening of short-term maternal and neonatal outcomes. It is time to discuss the risks and the short-term and more worrying long-term consequences for mothers and their offspring and the future impact on our healthcare system.
