An observational study of nutrition and physical activity behaviours, knowledge, and advice in pregnancy

Providers' Practices and Associated Factors in Educating Pregnant Women on the Prevention of Maternal Anemia During Antenatal Care Visits in Ujiji Municipality, Kigoma Region, Tanzania

BACKGROUND

Anemia in pregnancy is among the preventable severe public health problems, responsible for around 14.5% of maternal mortality in Tanzania. Antenatal visits are among the pillars that aid in reducing the burden of anemia in pregnancy. However, there are discrepancies in adherence and performance across different domains of Antenatal care (ANC) by healthcare workers. Therefore, this study examined providers' practices and associated factors in educating pregnant women on preventing maternal anemia during antenatal care visits in Kigoma and Ujiji Municipal Council in the Kigoma region.

METHODS

This was a cross-sectional design involving a total of 430 client exit interviews across 18 facilities. The association between the provision of maternal anemia education and other factors such as health facility level, age group, sex, economic activities, and ANC visitation was analyzed using multivariate logistic regression. p-values less than 0.05 were considered significant throughout the study.

RESULTS

The study revealed that most participants (70.4%) reported receiving anemia information during ANC visits. The most common topics were insecticide-treated nets (ITNs) (76%) and types of food to prevent anemia (74%), while 20.8% and 24.8% reported receiving information about worm infestation and deworming, respectively. Only 34.4% (95%CI: 26.5-43.3%) of pregnant women were informed of at least five topics.

CONCLUSIONS

The study reveals limited education provision on anemia among pregnant women. There is a discrepancy in topic coverage among facilities and individuals.

Effective dietary interventions during pregnancy: a systematic review and meta-analysis of behavior change techniques to promote healthy eating

Improving dietary intake during pregnancy can mitigate adverse consequences for women and their children. The effective techniques and features for supporting and sustaining dietary change during pregnancy and postpartum are minimally reported. The primary aims of this systematic review and meta-analysis were to summarise the effectiveness of dietary interventions for pregnant woman, identify which behaviour change techniques (BCTs) and intervention features were most frequently used and determine which were most effective at improving dietary intake. Six databases were searched to identify randomised control trials (RCTs) reporting on dietary intake in pregnant women over the age of sixteen, with an active intervention group compared to a control group receiving usual care or less intensive interventions. The Cochrane Risk of Bias Tool 1 was used to assess study validity. BCTs were coded by two authors using Michie et al.'s BCT taxonomy V1. A random effect model assessed intervention effects on indices of dietary quality and food groups (fruit, vegetables, grains and cereals, meat, and dairy) in relation to the use of BCTs and intervention features. Thirty- seven RCTs met the inclusion criteria. High heterogeneity was observed across intervention characteristics and measures of fidelity. Only half of the available BCTs were used, with eleven used once. The BCT category Reward and threat was successful in improving dietary quality and vegetable intake, whilst 'Action planning' (1.4) from the category Goals and planning significantly improved dietary quality. Interventions delivered by a nutrition professional and those that included group sessions improved dietary quality more than those delivered by other health professionals, research staff, or application-delivered interventions and delivered via other modalities. Future dietary interventions during pregnancy should incorporate and report on BCTs used in the intervention. Successful design elements for improving antenatal dietary intake may include multimodal interventions delivered by nutrition professionals and the use of Rewards and Goal setting.

Dietary Habits of Pregnant Women in Spain: The Role of Nutrition Education in Midwife Consultations

Background & Objectives: Correct nutrition during pregnancy is key to guaranteeing success at this stage of a woman's life, and nutritional education is the fundamental tool for achieving this. Studies carried out in different countries indicate that pregnant women do not comply with dietary and nutritional recommendations. Given the lack of evidence available in Spain and the importance of this knowledge to be able to assess the need for nutritional intervention in this group, the aim of this study focused on the current status of the issue in Spain: the quality of the diet of Spanish pregnant women and its conditioning factors. Methods: Two representative regions of the country were selected, one located in the north of Spain (Burgos) and the other in the south (Granada), and a descriptive, cross-sectional observational study (sample size: 771) was carried out using a questionnaire administered at the University Hospital of Burgos and the Hospital Clínico San Cecilio in Granada, which had previously been subjected to a process of evaluation by expert judgement. Results: Pregnant women presented an adequate diet quality (8.0 ± 2.0), according to the questionnaire used, despite their poor knowledge of food and nutrition (4.9 ± 1.6 out of 10). However, deficiencies were detected in the consumption of very interesting food groups from a nutritional point of view, such as legumes, nuts and fish (just 29.4%, 37.6% and 24.8% of the pregnant women met the recommendations, respectively) and insufficient physical exercise. The eating habits of pregnant women depend on their age, their country of origin, their level of education, their pre-pregnancy BMI, the knowledge acquired during pregnancy and the degree to which they put into practice the advice received from their midwife. Most pregnant women do not change their habits during pregnancy, although there are positive trends in this respect. Conclusion: The quality of the diet of the Spanish pregnant women surveyed, and their level of physical activity, could be improved by enhancing the nutritional education they receive during this stage of life. The role of the dietician in this respect, as part of multidisciplinary teams, should be the basis for future research.

Effectiveness of educational intervention in improving physical activity and nutritional performance among pregnant women: a pre-post quasi-experimental study using health belief model

Background

Physical activity and proper nutrition during pregnancy are crucial for maternal and fetal health. However, many pregnant women fail to meet recommended guidelines. This study aimed to assess the effectiveness of an educational intervention based on the Health Belief Model (HBM) in improving these behaviors.

Methods

A pre-post with control quasi-experimental study was conducted among 200 pregnant women (100 experimental and 100 control) in Shiraz, Iran. The intervention group attended eight weekly 50-minute educational sessions based on the HBM. Physical activity and nutritional performance were assessed using validated questionnaires at baseline and three months post-intervention. Data were analyzed using paired and independent t-tests, with effect sizes and 95% confidence intervals reported.

Results

The intervention significantly improved physical activity (mean score: 29.25 ± 4.42 vs. 12.28 ± 4.36, p < 0.001) and nutritional performance across all food groups (p < 0.001) in the experimental group compared to the control group. Key constructs of the HBM, including perceived sensitivity, severity, benefits, self-efficacy, and cues to action, showed significant increases with notable effect sizes and 95% confidence intervals, while perceived barriers significantly decreased (p < 0.001).

Conclusions

The educational intervention based on the HBM effectively improved physical activity and nutritional performance among pregnant women. Integrating such programs into routine prenatal care is recommended, with emphasis on personalized counseling, regular follow-ups, and spousal involvement to sustain behavioral changes and promote maternal and fetal health.

Nutrition education in the midwife consultation room. A cross sectional survey in Spain

BACKGROUND

Diet during pregnancy is a key factor in the success of pregnancy. However, several studies have found pregnant women have low adherence to dietary recommendations. The midwife is a key health professional to provide nutrition education for pregnant women. Thus, it is important to know in detail her role in this respect.

AIM

To explore how Spanish midwives undertake nutrition education in order to assess the need for specific interventions aimed at improving the health of pregnant women.

METHODS

A cross-sectional descriptive observational study was undertaken using an online questionnaire (466 responses).

FINDINGS

Spanish midwives recognise the importance of nutrition in pregnancy and that advising pregnant women in this regard is part of their role. In fact, all community midwives discuss nutrition to pregnant women, although they recognise that they do not feel particularly comfortable in dealing with certain topics, which could be related to a lack of mastery of the subjects. Midwives (56.5 %) rated the nutrition training their received as poor.

CONCLUSION

In order to guarantee the quality in the nutrition education provided by Spanish midwives to promote the health of pregnant women, our results demonstrate the importance of strengthening both the nutrition content of midwives' training programmes and the ongoing support they receive throughout their professional life.

Dietary Habits and Nutritional Knowledge of Pregnant Women: The Importance of Nutrition Education

A good diet during pregnancy is associated with improvements to maternal and fetal health. Nevertheless, excessive weight gain during pregnancy has been reported in several studies. The aim of this review is to determine the dietary habits of pregnant women (measured according to their degree of adherence to the Mediterranean diet, a reference in dietary quality), their knowledge of food and nutrition, and their perceptions of the nutritional education received during their pregnancy, in order to detect intervention needs within that group. The bibliographic search was conducted on three databases (Medline, PubMed central, and Web of Science), using the keywords "pregnancy", "Mediterranean diet", "nutrition knowledge", "nutritional education", and some synonyms. The final selection included 68 original articles. The available evidence indicated that, although pregnant women were aware of the importance of nutrition during pregnancy, their habits showed some room for improvement in terms of diet and physical exercise. Lack of adequate advice was the main barrier to the practice of healthy habits that pregnant women encountered; they considered that the information they received during pregnancy follow-up visits was inadequate. However, the success of interventions within different countries is a source of hope for well-structured nutrition education throughout pregnancy. The lack of nutrition-related knowledge among pregnant women could be originally related to poorly planned nutrition education from healthcare providers. Research focused on the consultations with these healthcare providers could be of help when proposing strategies to improve the content, the depth, and the duration of nutrition education sessions. It should, in any case, be noted that the available evidence in this field is limited to certain geographical origins. Therefore, research that uncovers evidence in different countries will be useful for learning about the factors that condition the habits of pregnant women and, in that way, guide strategies for the improvement of the health of expectant mothers during that stage in their lives.

Access to nutrition advice and knowledge, attitudes and practices of pregnant women in Ireland: A cross-sectional study

BACKGROUND

Healthy nutritional status, appropriate gestational weight gain and a balanced diet are important predictors of perinatal health outcomes. However, gaps exist in the translation of nutrition recommendations into dietary practices of women before and during pregnancy. The present study explored the relationship between access to nutrition advice, nutrition knowledge, attitudes and practices among pregnant women.

METHODS

Pregnant women aged > 18 years in Ireland were eligible to complete a self-administered survey consisting of four subsections (demographics, nutrition knowledge, attitudes and practices) delivered online through Qualtrics.

RESULTS

In this convenience sample (n = 334, median [interquartile range] gestation, 25.0 [16.0, 34.0] weeks), 85% had at least an honours bachelor degree and 88.9% planned their pregnancy. Two out of five women received nutrition advice during their pregnancy, mostly from a midwife. Based on the percentage of correct answers (of 15 questions), women with previous nutrition education (e.g., school home economics) had better median [interquartile range] nutrition knowledge than those with none (80.0% [66.7, 86.7%] vs. 73.3% [60.0, 80.0%], p < 0.001). Those who received nutrition advice during pregnancy did not score higher than those who did not (73.3% [66.7, 80.0%] vs. 73.3% [66.7, 80.0%], p = 0.6). Over three-quarters of participants considered nutritional supplement use to be very or extremely important. Although 73.6% and 92.4% took supplements prior to and during pregnancy, only 25.7% reported compliance with periconceptional folic acid supplementation guidelines. Half of respondents considered healthy eating during pregnancy as very or extremely important.

CONCLUSIONS

Access to nutrition advice during pregnancy was inadequate with poor nutrition knowledge, attitudes and practices observed. Accessible, evidence-based nutrition education for women prior to and during pregnancy is required.

Physical activity and associated factors in Australian women during pregnancy: A cross-sectional study

ISSUE ADDRESSED

Whilst the benefits of regular physical activity during pregnancy are well known, the few studies conducted in Australian pregnant women suggest that most do not meet recommended exercise guidelines. The aim of this study was to determine the levels of physical activity, sedentary behaviours, and associated factors in Australian pregnant women.

METHODS

A random sample of pregnant women (N = 780) of (mean [SD]) 31 (5) years of age completed a questionnaire describing weekly physical activity and sedentary behaviours. A number of potential risk factors, including socio-demographic characteristics and ethnicity, were investigated using logistic regression.

RESULTS

Approximately one-third (34%) of women were classified as "active"; however, only 7% of women performed the recommended amount of physical activity according to Australian guidelines. Women reported (mean [95% CI]) sitting for 8 (7.8-8.2) hours and lying down during the day for 0.5 (0.5-0.6) hour while pregnant. Being university educated (OR [95% CI]) (2.87 [1.6-4.9]), in paid employment (2.12 [1.14-3.94]) and having a lower body mass index (0.91 [0.87-0.95]) were factors associated with being active.

CONCLUSION

Australian women performed low levels of physical activity during pregnancy and spend long periods of time in sedentary behaviours. SO WHAT?: There is a strong need for a concerted health promotion strategy to endorse increased physical activity, along with a reduction in sedentary behaviours, during pregnancy to support better maternal outcomes in Australia.

Navigating Pregnancy: Information Sources and Lifestyle Behavior Choices-A Narrative Review

Background: Accessible health information during pregnancy is important to positively affect maternal and fetal health. However, the quality and accuracy of health information can greatly vary across numerous sources. This narrative review is aimed at summarizing the literature on pregnant individuals' information sources and how these sources influence their habits toward GWG, PA, and nutrition. Such data will highlight preferences and needs, reveal challenges, and identify opportunities for improvement. Methods: We searched PubMed for studies published in the last decade. Out of 299 studies initially identified, 20 (16 quantitative and four qualitative) met the eligibility criteria (investigating information sources and their influence on health habits toward GWG, PA, nutrition, pregnant participants, adequate data reporting, and being available in full text). Results: Primary sources of health information varied. The Internet (26%-97%) and healthcare providers (HCPs) (14%-74%) predominated, followed by family/friends (12%71%), books/magazines (49%-65%), and guidelines/brochures (25%-53%). Despite the widespread use of the Internet, HCPs were considered the most reliable source. The use of the Internet to retrieve health information was reported to be 2-4 h a week, and < 50% discussed the online information with their HCP. The Internet was also used as a supplementary resource on topics raised by HCPs. Regarding the influence on health habits, the Internet, HCPs, media, and family positively influenced GWG and promoted adherence to recommended guidelines (OR = 0.55-15.5). Only one study showed a positive association between Internet use and PA level. The Internet, media, HCPs, and information brochures were associated with better adherence to nutritional recommendations. Conclusions: Pregnant individuals relied on the Internet and HCP, with a preference for the Internet despite trust in midwives. Several sources of health information were positively associated with adherence to GWG and nutrition recommendations. Improving the quality of online information should be a priority for policymakers and health authorities.

Health System and Individual Barriers to Supporting Healthy Gestational Weight Gain and Nutrition: A Qualitative Study of the Experiences of Midwives and Obstetricians in Publicly Funded Antenatal Care in Tasmania, Australia

Individual and health system barriers can impede clinicians from supporting weight-related behaviour change for pregnant women, particularly in publicly funded antenatal care accessed by women from diverse socioeconomic backgrounds. The aim was to understand clinicians' experiences of supporting healthy gestational weight gain for pregnant women in a publicly funded antenatal setting. The work was undertaken to guide the implementation of systems changes, resource development, and workforce capacity building related to nutrition, physical activity, and gestational weight gain in the service. The qualitative descriptive study used purposive sampling and semi-structured interviews conducted between October 2019 and February 2020. Nine midwives and five obstetricians from a publicly funded hospital antenatal service in Tasmania, Australia participated. Interview transcripts were analysed using inductive thematic analysis. The three dominant themes were prioritising immediate needs, continuity of care support weight-related conversations, and limited service capacity for weight- and nutrition-related support. The subthemes were different practices for women according to weight and the need for appropriately tailored resources. Improving access to continuity of care and clinician training, and providing resources that appropriately consider women's socioeconomic circumstances and health literacy would enhance the ability and opportunities for clinicians to better support all women.

Antenatal care addressing gestational weight gain (GWG): a cross sectional study of pregnant women's reported receipt and acceptability of recommended GWG care and associated characteristics

BACKGROUND

The Australian Clinical Practice Guidelines for Pregnancy Care recommend that during the first and subsequent antenatal visits all pregnant women are weighed; advised of recommended gestational weight gain (GWG), dietary intake and physical activity; and offered referrals for additional support if needed. The extent to which these recommendations are implemented and women's acceptability of recommended care is unknown. This study examines women's reported receipt and acceptability of guideline care for GWG, and characteristics associated with receipt of such care and its acceptability.

METHODS

From September 2018 to February 2019 a telephone survey was undertaken with women who had recently had a baby and received antenatal care from five public maternity services within a health district in Australia. Women self-reported their demographic characteristics, and receipt and acceptability of recommended GWG care. Receipt and acceptability of such care, and their association with the characteristics of women and the maternity service they attended, were examined using descriptive statistics and multivariable logistic regression analyses.

RESULTS

Of 514 women, 13.1% (95%CI:10.3-16.5) reported that they received an assessment of weight at both their first and a subsequent antenatal visit, and less than one third (30.0%; 95%CI:26.0-33.9) received advice on their recommended GWG range, dietary intake and physical activity. Just 6.6% (95%CI:4.8-9.1) of women reported receiving all assessment and advice components of recommended antenatal care, and 9.9% (95%CI:7.6-12.8) of women reported being referred for extra support. Women who were younger (OR = 1.13;95%CI:1.05-1.21), identifying as Aboriginal and Torres Strait Islander (OR = 24.54;95%CI:4.98-120.94), had a higher pre-pregnancy BMI (OR = 1.13;95%CI:1.05-1.21), were experiencing their first pregnancy (OR = 3.36;95%CI:1.27-8.86), and lived in a least disadvantaged area (compared to mid-disadvantaged area (OR = 18.5;95%CI:2.6-130.5) and most disadvantaged area (OR = 13.1;95%CI:2.09-82.4)) were more likely to receive recommended assessment and advice. Most Aboriginal (92%) and non-Aboriginal (93%) women agreed that recommended GWG care is acceptable.

CONCLUSION

Most women perceive antenatal care for GWG as recommended by the Clinical Practice Guidelines as acceptable, but did not receive it. When provided, such care is not delivered consistently to all women regardless of their characteristics or those of the maternity service they attend. There is a need for service-wide practice change to increase routine GWG care in pregnancy for all women.

A prospective observational evaluation of an online health care professional training program to promote healthy pregnancy weight gain

ISSUE ADDRESSED

A lack of programs to develop clinician knowledge and confidence to address weight gain within pregnancy is a barrier to the provision of evidence-based care.

AIM

To examine the reach and effectiveness of the Healthy Pregnancy Healthy Baby online health professional training program.

METHODS

A prospective observational evaluation applied the reach and effectiveness elements of the RE-AIM framework. Health professionals from a range of disciplines and locations were invited to complete questionnaires before and after program completion assessing objective knowledge and perceived confidence around aspects of supporting healthy pregnancy weight gain, and process measures.

RESULTS

There were 7577 views across all pages over a year period, accessed by participants across 22 Queensland locations. Pre- and post- training questionnaires were completed 217 and 135 times, respectively. The proportion of participants with scores over 85% and of 100% for objective knowledge was higher post training (P ≤ .001). Perceived confidence improved across all areas for 88%-96% of those who completed the post- training questionnaire. All respondents would recommend the training to others.

CONCLUSIONS

Clinicians from a range of disciplines, experience and locations accessed and valued the training, and knowledge of, and confidence in delivering care to support healthy pregnancy weight gain improved after completion. SO WHAT?: This effective program to build the capacity of clinicians to support healthy pregnancy weight gain offers a model for online, flexible training highly valued by clinicians. Its adoption and promotion could standardise the support provided to women to encourage healthy weight gain during pregnancy.

Women Who Give Birth Preterm Do Not Meet Dietary Guidelines During Pregnancy

PURPOSE

To evaluate maternal dietary intake during pregnancy compared with the 2015-2020 and 2020-2025 Dietary Guidelines for Americans (DGA).

STUDY DESIGN AND METHODS

A retrospective observational study design was used. The cohort included women who gave birth to preterm infants between 25 1/7 weeks and 33 6/7 weeks of gestation. Within 2 weeks of birth, participants were asked to recall their diet in the last month of pregnancy using the Dietary Screener Questionnaire. Participants' dietary intakes were compared to current 2020-2025 DGA that include specific recommendations for pregnant women and prior 2015-2020 DGA that were in place during the study period but were not pregnancy-specific.

RESULTS

Forty-five women participated in the study. None met the 2015-2020 or 2020-2025 DGA recommended intake of all seven dietary components. When compared to both DGAs, 2.2% of participants met the recommended dairy intake, 26.7% met the calcium intake, 15.6% were below the threshold for added sugar, and none met the vegetable or whole grain intake. When compared to the 2015-2020 DGA, 28.9% met the fruit intake and 2.2% met the fiber intake. However, when compared to the 2020-2025 DGA, only 2.2% met the fruit intake and none met the fiber intake.

CLINICAL IMPLICATION

Women who gave birth preterm did not adhere to the 2015-2020 or 2020-2025 DGA recommendations in the last month of pregnancy. Nurses are uniquely positioned to provide pregnant women with nutritional screening and counseling as part of routine prenatal care.

Nutrition knowledge among pregnant women in Lebanon: A cross-sectional study

BACKGROUND

Women's knowledge of the nutritional guidelines during pregnancy can affect the health and nutritional status of both mother and child. Having good nutritional information related to maternal dietary intake and healthy lifestyles is therefore of great importance. However, there is limited published research that demonstrates pregnant women's knowledge of the nutritional guidelines during pregnancy in Lebanon.

OBJECTIVE

To assess the knowledge on food sources and energy recommendations as well as food safety practices and diet-health relationship among women during pregnancy in Lebanon.

DESIGN

A cross-sectional study.

METHODS

The study was conducted at prenatal care clinics in Lebanon, and all pregnant women present, regardless of nationality, were invited to complete the self-administered nutrition knowledge questionnaire. The study assessed five different nutrition knowledge domains (food sources of nutrients, dietary behaviors, food safety knowledge, micronutrients for fetal development, and energy requirements and weight gain) and the demographic characteristics of pregnant women who completed a multidimensional online survey based on validated and existing measures.

RESULTS

Four-hundred and ten responses were obtained. Approximately half of respondents (47%) held a university degree, for 42% of women this was their first pregnancy, and 71% had a planned pregnancy. Among the different nutrition knowledge domains, the highest levels of knowledge were for the behaviors that can minimize the effect of nausea/vomiting, heartburn, and constipation during pregnancy (63.9%) and the lowest levels of knowledge was for the importance of iodine and omega-3 fatty acids in pregnancy (28.4%). Most of females knew about food safety practices during pregnancy (72.9%) but less than half were knowledgeable about listeriosis contamination (45.9%), and the types of fish that are the safest to select during pregnancy (47.8%).

CONCLUSION

Despite the fact that pregnant women had an adequate level of knowledge in different nutrition-related areas, there was inadequate level of awareness related to critical nutrients and behaviors that can have adverse effects on mother and/or baby. Therefore, there is a need to focus on specific maternal nutrition aspects such as iron-rich foods, listeriosis food contamination, and nutrients that aid in fetal brain and retina development.

Maternal diet quality and associations with plasma lipid profiles and pregnancy-related cardiometabolic health

PURPOSE

To assess the relationship of early pregnancy maternal diet quality (DQ) with maternal plasma lipids and indicators of cardiometabolic health, including blood pressure (BP), gestational diabetes mellitus (GDM) and gestational weight gain (GWG).

METHODS

Women (n = 215) aged 18-40 years with singleton pregnancies were recruited at 10-20 weeks gestation. Diet quality was assessed by the Dietary Guideline Index, calculated at early ([mean ± SD]) (15 ± 3 weeks) and late (35 ± 2 weeks) pregnancy. Lipidomic analysis was performed, and 698 species across 37 lipid classes were measured from plasma blood samples collected at early (15 ± 3 weeks) and mid (27 ± 3 weeks)-pregnancy. Clinical measures (BP, GDM diagnosis, weight) and blood samples were collected across pregnancy. Multiple linear and logistic regression models assessed associations of early pregnancy DQ with plasma lipids at early and mid-pregnancy, BP at three antenatal visits, GDM diagnosis and total GWG.

RESULTS

Maternal DQ scores ([mean ± SD]) decreased significantly from early (70.7 ± 11.4) to late pregnancy (66.5 ± 12.6) (p < 0.0005). At a false discovery rate of 0.2, early pregnancy DQ was significantly associated with 13 plasma lipids at mid-pregnancy, including negative associations with six triglycerides (TGs); TG(54:0)[NL-18:0] (neutral loss), TG(50:1)[NL-14:0], TG(48:0)[NL-18:0], TG(52:1)[NL-18:0], TG(54:1)[NL-18:1], TG(50:0)[NL-18:0]. No statistically significant associations were found between early pregnancy DQ and BP, GDM or GWG.

CONCLUSION

Maternal diet did not adhere to Australian Dietary Guidelines. Diet quality was inversely associated with multiple plasma TGs. This study provides novel insights into the relationship between DQ, lipid biomarkers and cardiometabolic health during pregnancy.

Different experiences of weight management and physical activity during pregnancy - a qualitative study of women and healthcare professionals in Australia

OBJECTIVE

Pregnancy is often described as a pivotal life stage for women, where regular contact with health professionals may play an important role in lifestyle awareness. This study explored the knowledge, practices, and beliefs of health professionals and pregnant women regarding physical activity and weight management during the antenatal period.

METHODS

A qualitative study was undertaken in southeastern Australia using individual interviews. Recruitment sought women of gestation >12 weeks, experiencing an uncomplicated pregnancy (n = 6), and antenatal health professionals including midwives (n = 4) and an obstetrician (n = 1). Data were analysed using Interpretive Phenomenological Analysis.

RESULTS

Three major themes emerged: (1) women rely on multiple sources of pregnancy-related healthy lifestyle information; (2) discussions around healthy lifestyle behaviours are low priority and often inconsistent; and (3) lifestyle-related topics perceived as sensitive make some conversations and actions difficult.

CONCLUSIONS

Pregnant women expressed gaps in lifestyle-related knowledge and education being provided by health professionals. In turn, health professionals expressed difficulty discussing sensitive topics such as weight with pregnant women and had limited knowledge of pregnancy-specific physical activity guidelines. The themes generated by this study may form the foundation for further research to inform clinical policy and practice regarding advice in antenatal care.

Examining Enhanced Implementation of Routine Antenatal Care Practices to Support Healthy Pregnancy Weight Gain

INTRODUCTION

Current antenatal guidelines advocate for regular weighing of women during their pregnancy, with supportive conversations to assist healthy gestational weight gain (GWG). To facilitate overcoming weight monitoring barriers, a pregnancy weight gain chart (PWGC), coupled with brief intervention advice, was implemented in 2016 to guide provider and woman-led routine weight monitoring. This study aimed to examine the extent to which the use of PWGCs and routine advice provision were normalized into routine antenatal care following enhanced implementation strategies and whether this led to a change in GWG.

METHODS

This pre-post study included data from 2010 (preimplementation), 2016, and 2019 (postimplementation). A retrospective audit of health records and PWGCs was undertaken to assess adherence to chart use and evaluate GWG outcomes. A survey was sent to women in 2010 and repeated in 2019 to understand the advice women received from health care professionals.

RESULTS

Compared with the preimplementation cohort (2010), more women achieved a healthy GWG in 2019 (42% vs 31%, P = .04). In 2019, having 3 or more weights recorded was associated with a reduction in excess GWG (P = .028). More women reported receiving helpful advice about healthy GWG in 2019 compared with 2010, although minimal changes to advice received about nutrition and physical activity were observed.

DISCUSSION

Enhanced implementation strategies and ongoing efforts to optimize supportive antenatal care practices are required to effect positive change in GWG. Further evaluation of the perspectives of pregnant women and counseling practices of health professionals is needed.

Nutritional Education in the Midwife's Consultation Room

Evidence of the importance of maternal nutrition during pregnancy is growing, and midwives are the healthcare professionals in charge of monitoring pregnancy. In the present review, the aim is therefore to look at the relevant contributions on midwifery and the role of midwifery in the provision of nutritional education. Searches were conducted on three databases-Medline, PubMed Central, and Web of Science-using two key search terms ("nutrition" and "midwives") and their synonyms, for an extensive set of results. The final selection consisted of 27 original papers, most of which concerned the nutritional knowledge of midwives, their training, and their views, attitudes, and practices within the field of nutrition. According to the findings, although the midwives considered nutritional education to be part of their role and they agreed on the importance of nutrition during pregnancy, their knowledge of this topic was poor, perhaps due to inadequate nutritional education during their midwifery training. Academic programs on midwifery must therefore be reviewed, so as to increase the workload of nutrition-related subjects, in order to reinforce the corresponding knowledge bases of future midwives. In addition, based on the success of the nutritional interventions discussed in the present review, these sorts of initiatives could be of utmost importance to improve the knowledge of practicing midwives. In any case, it must be highlighted that the available evidence discussed in this review was drawn from only a few countries around the world. Further studies involving midwives of varied origins are therefore needed. Such research would be of immense assistance in the design of the corresponding nutritional interventions in the field, so as to improve the health of pregnant women.

Is Health Education among the Decisive Factors for the Diet Quality of Pregnant Women in Poland?

Health education (HE), an educational process that leads to increased nutritional awareness and improved health, is one of the factors influencing diet quality (DQ) during pregnancy. The aim was to evaluate the DQ of pregnant women and its determinants considering their HE. The study included 122 pregnant women aged 20-40 years. DQ was assessed using the Kom-PAN^® questionnaire and the Pro-Healthy Diet Index (pHDI). Data collected included dietary habits, socio-demographic data, education level, place of residence, and maternal lifestyle-related characteristics, namely, pre-pregnancy weight, trimester of pregnancy, and pre-pregnancy and pregnancy physical activity (PA). Weekly energy expenditure was determined using the Polish version of the PPAQ questionnaire. HE at school more than tripled the odds of a higher DQ. Women in their second trimester were 54% more likely to have a higher DQ than women in their third trimester of pregnancy. Undertaking pre-pregnancy PA increased the odds of a higher DQ 2.5 times. Comparative analyses performed in a group of women with HE (HEG, n = 33) and without HE (nHEG, n = 89) showed better DQ in the former, but this was still unsatisfactory in health-promoting properties. The results obtained showed that the HE and trimester of pregnancy and pre-pregnancy Pa influenced DQ in pregnant women.

Nutritional Health Knowledge and Literacy among Pregnant Women in the Czech Republic: Analytical Cross-Sectional Study

Adequate nutrition and the nutritional status of pregnant women are critical for the health of both the mother and the developing foetus. Research has shown a significant impact of nutrition on the child's health and the future risk of developing chronic noncommunicable diseases (NCDs), such as obesity, diabetes, hypertension, and cardiovascular disease. There is currently no data on the level of nutritional knowledge of Czech pregnant women. This survey aimed to evaluate their level of nutritional knowledge and literacy. An analytical cross-sectional study was conducted in two healthcare facilities in Prague and Pilsen between April and June 2022. An anonymous self-administered paper-form questionnaire for assessing the level of nutritional knowledge (40 items) and the Likert scale for assessing nutrition literacy (5 items) were used. A total number of 401 women completed the questionnaire. An individual's nutritional knowledge score was calculated and compared with demographic and anamnestic characteristics using statistical methods. The results showed that only 5% of women achieved an overall nutritional score of 80% or more. University education (p < 0.001), living in the capital city (p < 0.001), experiencing first pregnancy (p = 0.041), having normal weight and being overweight (p = 0.024), and having NCDs (p = 0.044) were statistically significantly associated with a higher nutritional knowledge score. The lowest knowledge scores were found in the areas of optimal energy intake, optimal weight gain, and the role of micronutrients in diet during pregnancy. In conclusion, the study shows limited nutrition knowledge of Czech pregnant women in some areas of nutrition. Increasing nutritional knowledge and nutrition literacy in Czech pregnant women is crucial for supporting their optimal course of pregnancy and the future health of their offspring.

Strengthening maternal nutrition counselling during routine health services: a gap analysis to guide country programmes

OBJECTIVE

The WHO recommends counselling on healthy eating, weight gain, and physical activity during antenatal care (ANC) and postnatal care (PNC), yet advice and information are often not tailored to women's nutritional needs and contexts. The purpose of the gap analysis was to identify key elements related to the provision of maternal nutrition counselling during routine health contacts and provide programme considerations to strengthen quality service delivery.

DESIGN

A search of PubMed, Cochrane Library, CINAHL Plus and Scopus databases was conducted to retrieve studies from January 2010 to December 2021. Using inclusion criteria, quantitative, qualitative and mixed methods studies were included in the final gap analysis.

SETTING

Low-, middle- and high-income country contexts.

PARTICIPANTS

Following application of gap analysis criteria, thirty-seven articles from sixteen countries were included in the analysis.

RESULTS

Gaps in delivery of maternal nutrition counselling include provider capacity building, frequency, content and delivery platforms. Globally, counselling on appropriate weight gain during pregnancy is often not delivered with the desired content nor quality, while targeted counselling to overweight and obese women was provided in several high-income country contexts. Delivery of maternal nutrition counselling through multiple delivery platforms demonstrated improvements in maternal diet and/or weight gain during pregnancy.

CONCLUSIONS

Strengthening the integration of maternal nutrition counselling into pre- and in-service curricula, routine health provider training, supportive supervision and provider mentoring is needed. Future efforts may consider generating global and regional weight gain guidelines and incorporating maternal nutrition counselling indicators as part of quality-of-care ANC/PNC standards and routine health systems.

Development and Validation of a Protocol for Pregnant Women Based on the Brazilian Dietary Guidelines

OBJECTIVE

 To develop and validate a protocol for the use of the Dietary Guidelines for the Brazilian Population (DGBP) in the individual dietary advice for pregnant women assisted in primary healthcare (PHC).

METHODS

 Methodological study that involved the elaboration of a protocol in six steps: definition of the format, definition of the instrument to evaluate food consumption, systematization of evidence on food and nutrition needs of pregnant women, extraction of DGBP recommendations, development of messages of dietary guidelines and content, and face validity. The analyses of the validation steps were carried out by calculating the Content Validity Index (CVI) and thematic content analysis.

RESULTS

 As products of the steps, the protocol structure was defined and the dietary advice for pregnant women were elaborated, considering physiological changes, food consumption, nutritional and health needs, and socioeconomic conditions of this population. The protocol was well evaluated by experts and health professionals in terms of clarity, relevance (CVI > 0.8), and applicability. In addition, the participants made some suggestions to improve the clarity of the messages and to expand the applicability of the instrument with Brazilian pregnant women.

CONCLUSION

 The instrument developed fills a gap in clinical protocols on dietary advice for pregnant women focused on promoting a healthy diet, contributing to a healthy pregnancy. In addition, it demonstrates potential to contribute to the qualification of PHC professionals and to the implementation of the DGBP recommendations.

Exploring the diets of mothers and their partners during pregnancy: Findings from the Queensland Family Cohort pilot study

AIM

Modifiable behaviours during the first 1000 days of life influence developmental trajectories of adult chronic diseases. Despite this, sub-optimal dietary intakes during pregnancy and excessive gestational weight gain are common. Very little is known about partners' dietary patterns and the influence on women's pregnancy dietary patterns. We aimed to examine dietary intake during pregnancy among women and their partners, and gestational weight gain patterns in the Queensland Family Cohort pilot study.

METHODS

The Queensland Family Cohort is a prospective, observational study piloted at a Brisbane (Australia) tertiary maternity hospital from 2018 to 2021. Participant characteristics, weight gain, dietary and nutrient intake were assessed.

RESULTS

Data were available for 194 pregnant women and their partners. Poor alignment with Australian Guide to Healthy Eating recommendations was observed. Highest alignment was for fruit (40% women) and meat/alternatives (38% partners) and lowest for breads/cereals (<1% women) and milk/alternatives (13% partners). Fewer women (4.4%-60.3%) than their partners (5.4%-92.3%) met guidelines for all micronutrient intakes from food alone, particularly folic acid, iodine, and iron. Women were more likely to meet daily recommendations for fruit, vegetables, dairy, bread/cereals, and meat/alternatives when their partners also met recommendations. Women with a higher pre-pregnancy body mass index were more likely to gain above recommended weight gain ranges.

CONCLUSIONS

In this contemporary cohort of pregnant women and their partners, sub-optimal dietary patterns and deficits in some nutrients were common. There is an urgent need for evidence-informed public health policy and programs to improve diet quality during pregnancy due to intergenerational effects.

Maternal health literacy and health numeracy conceptualizations in public health: A scoping review

Despite unprecedented advancement in educational opportunities and access to information, maternal health literacy (MHL) and health numeracy (HN) skills remain low in North America. By enhancing MHL, the educated civic public-those who have the capacity, skills, and knowledge to apply prose and numerical health information-engages more proactively in public health practice. The purpose of this scoping review was to map the existing empirical evidence on MHL to work toward a better understanding of the practical implications for public health. We explored MHL and HN through the following research question: "How are maternal health literacy and health numeracy conceptualised in public health planning, implementation, and evaluation?" First, we employed a five-stage methodological framework for scoping reviews and used PRISMA-P to systematically identify eligible articles. Then, we used thematic analysis and an inductive approach guided by the research aims to identify themes related to how MHL and HN are conceptualised in empirical studies and developed an evidence table. Finally, two different reviewers coded articles using an inductive approach into six themes. We identified 1733 articles through a systematic search of five databases. After screening all the articles, 52 articles were included for thematic analysis. The final themes were: (i) sociocultural demographics; (ii) self-efficacy; (iii) communication; (iv) information seeking and operationalisation; (v) health status; and (vi) reasoning. The research evidence demonstrated limitations concerning the impact of sociocultural background on a mother's recognition of health problems and the extent of which patient-centred care is culturally and linguistically appropriate. The research evidence revealed an opportunity to address the sociocultural linguistic experience of mothers within public health practice. Our research team supports moving away from the biomedical model of evidence-based medicine and adopting evidence-based practice ensures healthcare providers develop a holistic understanding of the maternal health needs of socioculturally diverse mothers.

Perception of the Body Image in Women after Childbirth and the Specific Determinants of Their Eating Behavior: Cross-Sectional Study (Silesia, Poland)

Background: Episodes of loss of control over eating during pregnancy affect up to 36% of women during this period. Many women experience natural concerns about weight gain and body-shape changes during pregnancy and the postpartum period, and food cravings and fluctuations in eating patterns during these periods are physiological phenomena. However, pregnancy and the postpartum period may be an additional determinant of eating disorders. Women who perceive their own bodies as significantly deviating from the presented ideal are more likely to experience anxiety/anxiety related to it and also tend to exhibit abnormal eating behaviors. The perception of one’s body figure also plays an important role in maintaining psychological balance Aim: The aim of this study was to assess the perception of body image by postpartum women. The essence of the study was to see if there were psychomarkers associated with lack of control over eating, food restriction, and emotionally motivated eating in the study population. Material and methods: The study was conducted during the fall and winter of 2021. A total of 288 women participated in the study. The age of the subjects ranged from 21 to 45 years. Results: It was found that 198 women (68.8%) were dissatisfied with their current body weight and figure. Respondents with higher post-pregnancy body mass index showed dissatisfaction with their body shape (49.8%; H = 13.042; p = 0.001). Both body satisfaction and BMI level were significant components of the occurrence of pathological phenomena associated with the TFEQ-13 subscales (p < 0.05). Conclusions: Excessive focus on food restriction as well as lack of control over eating had some association with negative self-perception of body image, mainly in the form of body weight dissatisfaction. Eating behaviors showed an association with BMI level and weight satisfaction after pregnancy.

A theory driven, pragmatic trial implementing changes to routine antenatal care that supports recommended pregnancy weight gain

Background

Prevention of weight gain outside recommendations is a challenge for health services, with several barriers to best practice care identified. The aim of this pragmatic implementation study with a historical control was to examine the impact of implementing a service wide education program, and antenatal care pregnancy weight gain chart combined with brief advice on women’s knowledge of recommended gestational weight gain (GWG), the advice received and actual GWG.

Methods

The PRECEDE PROCEED Model of Health Program planning guided intervention and evaluation targets and an implementation science approach facilitated service changes. Pregnant women < 22 weeks’ gestation attending the antenatal clinic at a metropolitan birthing hospital in Australia were recruited pre (2010, n = 715) and post (2016, n = 478) implementation of service changes. Weight measurements and questionnaires were completed at recruitment and 36 weeks’ gestation. Questionnaires assessed advice received from health professionals related to healthy eating, physical activity, GWG, and at recruitment only, pre-pregnancy weight and knowledge of GWG recommendations.

Results

Women who correctly reported their recommended GWG increased from 34% (pre) to 53% (post) (p < 0.001). Between pre and post implementation, the advice women received from midwives on recommended GWG was significantly improved at both recruitment- and 36-weeks’ gestation. For normal weight women there was a reduction in GWG (14.2 ± 5.3 vs 13.3 ± 4.7 kg, p = 0.04) and clinically important reduction in excess GWG between pre and post implementation (31% vs 24%, p = 0.035) which remained significant after adjustment (AOR 0.53 [95%CI 0.29–0.96]) (p = 0.005).

Conclusions

Service wide changes to routine antenatal care that address identified barriers to supporting recommended GWG are likely to improve the care and advice women receive and prevent excess GWG for normal weight women.

Effective factors on nutrition behaviors of pregnant women based on the beliefs, attitudes, subjective norms, and enabling factors model: A cross-sectional study

BACKGROUND

One of the useful models in health education is the Beliefs, Attitudes, Subjective Norms, and Enabling Factors (BASNEF) model. The model is used to study behavior and to plan for change it and to determine the factors that influence people's decision-making. The aim of this study was to investigate the factors affecting the nutritional behavior of pregnant women based on BASNEF model.

MATERIALS AND METHODS

This cross-sectional study was performed on 360 pregnant women referring to health centers of Tabriz-Iran by two-stage cluster sampling method from April to December 2016. Data were collected using sociodemographic, nutrition subdomain of Health Promoting Lifestyle-II (HPLP-II), and researcher-made questionnaire based on constructs of BASNEF model. Data were analyzed using the SPSS software version 21 and Pearson correlation test and General Linear Model (GLM).

RESULTS

Mean ± standard deviation (SD) of nutrition subdomain of HPLP-II was 24.65 ± 4.75 within the range 9-36. Mean ± SD of BASNEF model constructs (score range) was also obtained as 45.30 ± 10.80 (0-100), 17.98 ± 2.40 (8-24), 9.30 ± 2.82 (0-20) and 2.47 ± 1.74 (0-6) for belief, attitude, subjective norms, and enabling factors, respectively. Based on the GLM, there was significant relationships between nutritional behavior and BASNEF model constructs (belief [P < 0.001], attitude [P = 0.043], enabling factors [P < 0.001], and subjective norms [P = 0.038]) as well as the variables of job, husband's education, and job and sufficiency of income for expenses.

CONCLUSION

The results of the present study showed the impact of BASNEF model constructs and some sociodemographic variables on nutrition behaviors in pregnant women. Therefore, in order to improve nutrition behaviors of pregnant women, designing and implementation of interventions based on the BASNEF model are recommended.

Relationship between Eating Habits, Physical Activity and Tobacco and Alcohol Use in Pregnant Women: Sociodemographic Inequalities

Pregnant women must maintain or acquire healthy habits during pregnancy to protect both their own health and their child's. Such habits include an adequate eating pattern along with good adherence to the intake of certain supplements, practice of moderate physical activity and avoiding the consumption of toxic products such as tobacco and alcohol. The objective of this study is to assess the interrelation between such habits and their association with sociodemographic variables. To such end, a cross-sectional study was conducted with a representative sample of pregnant women who attended the scheduled morphology echography consultation at the 20th gestational week in their reference public hospital in the city of Seville (Spain). Results: Younger pregnant women and with lower educational levels are the ones that present the worst eating habits and the highest smoking rate. Pregnant women with lower educational levels are the least active. Non-smoking pregnant women present better eating habits than those who smoke. Pregnant women with lower educational levels are those who accumulate more unhealthy habits during pregnancy. This should be taken into account when planning the health care provided to pregnant women and in public health intersectoral policies.

Understanding Determinants of Pregnant Women's Knowledge of Lifestyle-Related Risk Factors: A Cross-Sectional Study

Research indicates that a woman’s lifestyle during pregnancy influences her child’s health and development. Therefore, women need to possess sufficient knowledge regarding the elements of a healthy lifestyle during pregnancy. To date, there has been little research on the assessment of lifestyle knowledge of pregnant women in the perinatal healthcare setting. This study describes the development and application of a knowledge-based questionnaire for pregnancy to be used in a lifestyle intervention trial conducted in Germany. Within the trial, pregnant women receive counselling on lifestyle topics. These topics are based on the German initiative ‘Healthy Start—Young Family Network’ (GiL), which provides evidence-based recommendations regarding diet and lifestyle before and during pregnancy. These serve as a basis for health professionals who provide counselling on healthy lifestyle choices during the antenatal period. The questionnaire consists of eight items, each of which can be answered using ‘Yes’, ‘No’ or ‘Don’t know’. The pregnant women who completed the questionnaire at baseline around the twelfth week of gestation were recruited within the host trial from gynaecological practices in Germany. Demographic variables and the respondents’ answers to the questionnaire were analysed using descriptive statistics and regression analyses. Descriptive statistics show that more than 85% of participants answered the majority of questions (n = 5) correctly. Questions on whether tap water is safe and the normal range for gestational weight gain (GWG) were answered correctly by about 62% and 74% of the women, respectively, and the question on whether it is beneficial to obtain information on breastfeeding at an early stage was answered correctly by about 29%. The results of the regression analyses indicate that age, gestational week, education and income are positive predictors for answering the questionnaire correctly. Nullipara and migration background are predictors for answering the questions incorrectly. This study indicates that there are gaps in women’s knowledge regarding lifestyle during pregnancy. Particular focus on certain topics, such as breastfeeding and normal GWG ranges, is still required during counselling. Our analysis shows that migration background is a predictor of insufficient knowledge and incorrect answers to the questions. Women with such backgrounds require special attention during antenatal counselling in order to cater to their needs and the gaps in their knowledge.

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.

New Zealand women's experiences of managing gestational diabetes through diet: a qualitative study

Background

For women with gestational diabetes mellitus (GDM) poor dietary choices can have deleterious consequences for both themselves and their baby. Diet is a well-recognised primary strategy for the management of GDM. Women who develop GDM may receive dietary recommendations from a range of sources that may be inconsistent and are often faced with needing to make several dietary adaptations in a short period of time to achieve glycaemic control. The aim of this study was to explore how women diagnosed with GDM perceive dietary recommendations and how this information influences their dietary decisions during pregnancy and beyond.

Methods

Women diagnosed with GDM before 30 weeks’ gestation were purposively recruited from two GDM clinics in Auckland, New Zealand. Data were generated using semi-structured interviews and thematic analysed to identify themes describing women’s perceptions and experiences of dietary recommendations for the management of GDM.

Results

Eighteen women from a diverse range of sociodemographic backgrounds participated in the study. Three interconnected themes described women’s perceptions of dietary recommendations and experiences in managing their GDM through diet: managing GDM is a balancing act; using the numbers as evidence, and the GDM timeframe. The primary objective of dietary advice was perceived to be to control blood glucose levels and this was central to each theme. Women faced a number of challenges in adhering to dietary recommendations. Their relationships with healthcare professionals played a significant role in their perception of advice and motivation to adhere to recommendations. Many women perceived the need to follow dietary recommendations to be temporary, with few planning to continue dietary adaptations long-term.

Conclusions

The value of empathetic, individually tailored advice was highlighted in this study. A greater emphasis on establishing healthy dietary habits not just during pregnancy but for the long-term health of both mother and baby is needed.

Monitoring Physical Activity Intensity During Pregnancy

For apparently healthy pregnant women, regular physical activity is recommended. The American College of Obstetricians and Gynecologists (ACOG) created recommendations for physical activity and exercise during pregnancy in 1985. At that time, pregnant women were advised to not exceed a heart rate of 140 beats per minute with physical activity. The heart rate recommendation was subsequently removed with the recommendations published in 1994, 2002, and 2015. In 2020, the ACOG updated its recommendations on physical activity for pregnant and postpartum women. The recommendation included exercising at a "fairly light to somewhat hard" perceived intensity and at less than 60-80% of age-predicted maximum heart rate, usually not exceeding a heart rate of 140 beats per minute. Women often seek advice from healthcare providers on physical activity during pregnancy, yet providers report concern about giving appropriate physical activity guidance. This paper summarizes the key scientific literature on monitoring absolute and relative exercise intensity in relation to the current ACOG recommendations, providing background on intensity-related concepts used in the recommendation. This paper also provides practical guidance to assist healthcare providers in relaying this information to pregnant women.

Eating Behaviors and Dietary Patterns of Women during Pregnancy: Optimizing the Universal 'Teachable Moment'

Understanding women's perceptions of eating behaviors and dietary patterns can inform the 'teachable moment' model of pregnancy. Our objectives were to describe eating behaviors and dietary patterns in pregnancy. This was a cross-sectional, national electronic survey. Women were ≥18 years of age, living in the United States, currently pregnant or less than two years postpartum, and had internet access. Age, education, race, and marriage were included as covariates in ordinal and binary logistic regressions (significance p < 0.05). Women (n = 587 eligible) made positive or negative changes to their diets, while others maintained pre-existing eating behaviors. The majority of women did not try (84.9 to 95.1% across diets) and were unwilling to try (66.6 to 81%) specific dietary patterns during pregnancy. Concerns included not eating a balanced diet (60.1 to 65.9%), difficulty in implementation without family (63.2 to 64.8%), and expense (58.7 to 60.1%). Helpful strategies included being provided all meals and snacks (88.1 to 90.6%) and periodic consultations with a dietitian or nutritionist (85 to 86.7%). Responses differed across subgroups of parity, body mass index, and trimester, notably in women with obesity who reported healthier changes to their diet (p < 0.05). Our study underscores the importance of tailoring care early to individual needs, characteristics, and circumstances.

Low Resting Energy Expenditure Is Associated with High Gestational Weight Gain Only When Resting Energy Expenditure Fluctuates

Resting energy expenditure (REE) may be useful for individualizing energy intake (EI) and physical activity (PA) goals, and in turn, regulating gestational weight gain (GWG). Limited research, however, has examined the association between REE and GWG. This study examined (1) change in REE from 14 to 28 gestation, (2) time-varying associations between REE and GWG, and (3) EI and PA patterns during the weeks when REE and GWG were significantly associated. Pregnant women with overweight/obesity (N = 27) participating in the Healthy Mom Zone study completed weekly point estimates of EI (back-calculation), PA (wrist-worn activity monitor), REE (mobile metabolism device), and weight (Wi-Fi scale) from 14 to 28 weeks gestation. Analyses included descriptives and time-varying effect modeling. REE fluctuated, increasing on average from 14 to 28 weeks gestation, but decreased at gestational weeks 17, 20, 21, 23, 26, and 28. Most women increased in REE; however there was large between-person variability in the amount of change. Associations between REE and GWG were small but time-varying; low REE was associated with high GWG between gestational weeks 25 to 28 when there was observably larger fluctuation in REE. Moreover, over half of the women were categorized as having excessive EI and most as low active during this time. EI needs may be overestimated and PA needs may be underestimated when REE is fluctuating, which may increase the risk for high second trimester GWG. Researchers should consider the role of REE to inform EI and PA goals to regulate GWG.

Pregnant women's perceptions of physical activity: Adaptation of the pregnancy physical activity questionnaire in Dubai, a multicultural society

Background: There are major health benefits of physical activity (PA) during pregnancy, yet there is scant data about a woman’s knowledge and understanding of these benefits globally.

Design and Methods: We aimed to evaluate the knowledge, attitude, and practice of pregnant women in the United Arab Emirates concerning exercise. We wanted to investigate why some women exercise while others do not exercise during pregnancy. We used a cross-sectional study using a paper-based questionnaire involving pregnant women at antenatal clinics in the Dubai health Authority. The Modified form of Pregnancy Physical Activity Questionnaire (PPAQ) was adapted in both Arabic and English and used in this study.

Results: Women aging 25-35 that had a higher educational level, were employed, having 1 or 2 previous pregnancies, and having better knowledge on the benefits of Physical Activity (PA) during pregnancy had better exercise profiles.

Conclusions: Our results demonstrate that the majority of the women that participated in our study were shown to have low PA during pregnancy. Better education and communication of the benefits of PA during pregnancy are needed to improve exercise among pregnant women in the UAE population. We found that improved education of women specific to PA with involvement of a healthcare provider were associated with an increase in PA during pregnancy.

Relative Importance of Determinants of Changes in Eating Behavior during the Transition to Parenthood: Priorities for Future Research and Interventions

Background: Healthy eating behavior throughout pregnancy and postpartum is important. This study aimed to investigate the perceived sex-specific importance of determinants of changes in eating behavior during pregnancy and postpartum. Methods: Fifty-four determinants were rated by first-time parents (n = 179) on their impact. Experts (n = 31) rated the determinants in terms of their modifiability, relationship strength, and population-level effect from which a “priority for research”-score was calculated. Results: During pregnancy, the three highest rated determinants by women were “health concerns”, “physiological changes”, and “fatigue”. Men perceived “health concerns”, “health consciousness”, and “influence of the pregnant partner” as important. Postpartum, the three highest rated determinants by women were “adaptation to rhythm of baby”, “baby becomes priority”, and “practical constraints because of the baby”. Men perceived “adaptation to rhythm of baby”, “fatigue”. and “(lack of) anticipation” as important. According to the experts, “professional influence”, “food knowledge”, and “home food availability” received high priority scores for both sexes and during both periods. Conclusions: Priority for research and interventions should go towards tailored family-based approaches focusing on food education in a broad sense taking into account aspects such as health consciousness, self-efficacy skills, and the social and home food environment while being supported by healthcare professionals.

Midwives' Experiences with and Perspectives on Online (Nutritional) Counselling and mHealth Applications for Pregnant Women; an Explorative Qualitative Study

Prenatal nutrition is a key predictor of early-life development. However, despite mass campaigns to stimulate healthy nutrition during pregnancy, the diet of Dutch pregnant women is often suboptimal. Innovative technologies offer an opportunity to develop tailored tools, which resulted in the release of various apps on healthy nutrition during pregnancy. As midwives act as primary contact for Dutch pregnant women, the goal was to explore the experiences and perspectives of midwives on (1) nutritional counselling during pregnancy, and (2) nutritional mHealth apps to support midwifery care. Analyses of eleven in-depth interviews indicated that nutritional counselling involved the referral to websites, a brochure, and an app developed by the Dutch Nutrition Centre. Midwives were aware of the existence of other nutritional mHealth apps but felt uncertain about their trustworthiness. Nevertheless, midwives were open towards the implementation of new tools providing that these are trustworthy, accessible, user-friendly, personalised, scientifically sound, and contain easy-digestible information. Midwives stressed the need for guidelines for professionals on the implementation of new tools. Involving midwives early-on in the development of future nutritional mHealth apps may facilitate better alignment with the needs and preferences of end-users and professionals, and thus increase the likelihood of successful implementation in midwifery practice.

Effectiveness of an intervention focusing on diet and walking during pregnancy in the primary health care service

Interventions during prenatal care can mitigate negative outcomes of a sedentary lifestyle and unhealthy diet during pregnancy. We aimed to evaluate the effectiveness of an intervention that promoted healthy diet and leisure-time walking during antenatal care in a pragmatic, controlled, non-randomized intervention study. Physicians and nurses from all health care units of the Family Health Strategy model of health assistance participated in educational training to promote leisure-time walking and healthy diet during antenatal care visits. Pregnant women who received health care from these professionals constituted the intervention group (n = 181). The control group (n = 172) included pregnant women who received routine antenatal care, in health care units of the traditional model of health assistance. Data were collected in each trimester of pregnancy. Diet was investigated using a food frequency questionnaire adapted from Risk and Protective Factors Surveillance System for Chronic Non-Comunicable Diseases Through Telephone Interview (Vigitel). Leisure-time walking in a typical week was assessed using questions from the Physical Activity in Pregnancy Questionnaire. There were positive effects on leisure-time walking during the second trimester and the third trimester of pregnancy and on the women who achieved 150 minutes per week of walking during the third trimester. The intervention reduced the risk of pregnant women consuming soft drinks and/or commercially prepared cookies in the third trimester. This lifestyle intervention was partially effective, tripling the proportion of pregnant women who achieved the recommended walking time and reducing by half the proportion of women who had a high weekly consumption of soft drinks and industrially processed cookies.

Overview of a new eHealth intervention to promote healthy eating and exercise in pregnancy: Initial user responses and acceptability

PURPOSE

The purpose of this project was to develop and evaluate an eHealth intervention to promote healthy lifestyle for pregnant women. The setting was a low socio-economic and multi-ethnic area in Melbourne, Australia.

METHODS

This paper briefly describes the development of the eHealth intervention, which was aimed at a low level of literacy, and the evaluation of the intervention by pregnant women. A basic descriptive survey was undertaken to evaluate user friendliness, usefulness and acceptability of the intervention.

RESULTS

The intervention was developed by a team of experts and forty pregnant women participated in the evaluation. Results indicated that participants found the intervention informative, useful and easy to navigate. They also identified some minor areas for improvement which will be addressed prior to proceeding to a formal controlled evaluation.

CONCLUSION

Results from this evaluation are encouraging and suggest that women found the intervention convenient, trustworthy and engaging. Most enjoyed navigating the website information. As such, it is likely to prove a useful support for delivering dietary and exercise information to pregnant women in the local low socio-economic area. Further formal evaluation will test the efficacy of the website in improving diet and exercise outcomes during pregnancy.

Pregnant Women Have Poor Carbohydrate Knowledge and Do Not Receive Adequate Nutrition Education

OBJECTIVES

In order to manage blood glucose levels in pregnancy, women need to know what and how much to eat, particularly for foods containing carbohydrate. The aim was to assess pregnant women's carbohydrate and standard serve size knowledge and examine whether health professionals provided nutrition education.

METHODS

Between July 2017 and April 2018 Australian pregnant women were recruited to complete an online survey, including a modified PedCarbQuiz carbohydrate knowledge questionnaire and an online buffet, where they selected images equivalent to one Australian Guide to Healthy Eating (AGHE) standard serve size.

RESULTS

186 pregnant women (mean age 30.9 years, SD = 4.7 years) 12-22 weeks gestation completed the survey. Participants achieved a median score of 27/36 for identification of carbohydrate-containing foods and a median score of 1/12 (range 0-11) for identification of grams of carbohydrate in specific portions. Participants achieved a median score of 14/22 (range 4-19) for identification of one AGHE standard serve of 11 carbohydrate-containing foods. Less than half (n = 92, 49.5%) received nutrition education from health professionals.

CONCLUSIONS FOR PRACTICE

Pregnant women had sub-optimal carbohydrate knowledge. This could contribute to impaired blood glucose concentrations and risk of adverse health outcomes in pregnancy. Opportunities for pregnant women to access nutrition advice from health professionals should be explored.

Implementation of the Living Well During Pregnancy Telecoaching Program for Women at High Risk of Excessive Gestational Weight Gain: Protocol for an Effectiveness-Implementation Hybrid Study

Background

Despite comprehensive guidelines for healthy gestational weight gain (GWG) and evidence for the efficacy of dietary counseling coupled with weight monitoring on reducing excessive GWG, reporting on the effectiveness of interventions translated into routine antenatal care is limited.

Objective

This study aims to implement and evaluate the Living Well during Pregnancy (LWdP) program in a large Australian antenatal care setting. Specifically, the LWdP program will be incorporated into usual care and delivered to a population of pregnant women at risk of excessive GWG through a dietitian-delivered telephone coaching service.

Methods

Metrics from the RE-AIM (Reach, Effectiveness, Adoption, Implementation, and Maintenance) framework will guide the evaluation in this hybrid effectiveness-implementation study. All women aged ≥16 years without pre-exiting diabetes with a prepregnancy BMI >25 kg/m² and gaining weight above recommendations at <20 weeks’ gestation who are referred for dietetic care during the 12-month study period will be eligible for participation. The setting is a metropolitan hospital at which approximately 6% of the national births in Australia take place each year. Eligible participants will receive up to 10 telecoaching calls during their pregnancy. Primary outcomes will be service level indicators of reach, adoption, and implementation that will be compared with a retrospective control group, and secondary effectiveness outcomes will be participant-reported anthropometric and behavioral outcomes; all outcomes will be assessed pre- and postprogram completion. Additional secondary outcomes relate to the costs associated with program implementation and pregnancy outcomes gathered through routine clinical service data.

Results

Data collection of all variables was completed in December 2020, with results expected to be published by the end of 2021.

Conclusions

This study will evaluate the implementation of an evidence-based intervention into routine health service delivery and will provide the practice-based evidence needed to inform decisions about its incorporation into routine antenatal care.

Prenatal Counseling throughout Pregnancy: Effects on Physical Activity Level, Perceived Barriers, and Perinatal Health Outcomes: A Quasi-Experimental Study

Physical activity during pregnancy has many health benefits. However, the physical activity level is insufficient throughout pregnancy and women report perceived barriers to physical activity. This study assessed the impact of a counseling intervention offered in addition to routine pregnancy care on physical activity patterns, perceived barriers, and perinatal health outcomes. A quasi-experimental trial was conducted in the Maternity Unit of a hospital in Guadeloupe (a French department). Ninety-six pregnant women were allocated to a control or intervention group. Regular physical activity counseling was dispensed to the women in the intervention group by trained healthcare providers. The physical activity level and the perceived barriers were assessed in each trimester. Outcomes for the perinatal health of the mother and child were measured throughout pregnancy and after delivery. The perceived barriers, such as a lack of information about the health benefits and risks over the two trimesters (all p < 0.05) and insecurity related to practice throughout pregnancy (all p < 0.05), were different in favor of the intervention group. There were no significant between-group differences for the major indices of physical activity, whether measured or reported. The intervention women reported significantly more sedentary activity compared with the control group in the third trimester, 64.7 (36.4–78.7) vs. 22.7 (9.4–49.8) MET-hours/week, respectively (p < 0.001). The perinatal health outcomes for the mother and child showed no significant differences. The intervention was unable to limit the decline in physical activity or improve health outcomes. However, it was associated with an improvement in the perception of barriers. Future research should focus on interventions that have a sufficient quantitative impact on perceived barriers in order to limit physical activity decline.

The Evidence Base in Exercise Knowledge of Pregnant Women: A Latent Class Analysis

BACKGROUND

Exercise has many benefits for women with uncomplicated pregnancies. However, poor exercise knowledge may contribute to problems or barriers that reduce a woman's level of exercise after becoming pregnant.

AIM

This study was performed to identify pregnancy exercise knowledge among pregnant women using latent class analysis and to examine the relationship between pregnancy exercise knowledge patterns and sociodemographic characteristics.

DESIGN

A descriptive, cross-sectional approach was used in this study.

METHODS

Participants were recruited from the prenatal outpatient departments of two hospitals and a certified prenatal center in Taipei, Taiwan. A total of 618 participants completed a pregnancy exercise knowledge test. The data were analyzed using WINMIRA and SPSS 20.0 software.

RESULTS

Two latent classes were identified based on exercise knowledge among pregnant women. The Accurate Knowledge group (n = 543, 87.9%), which had a higher latent trait for exercise knowledge (M = 1.31, SD = 0.94), was larger than the Limited Knowledge group (n = 75, 12.1%), which had a lower latent trait (M = -0.22, SD = 1.14). The principles of exercise for pregnant women, particularly the appropriate intensity and duration, may be difficult items for women in the Limited Knowledge group to understand. Women with Limited Knowledge had significantly lower education levels and greater rates of unemployment, multiparity, and miscarriage than women in the Accurate Knowledge group.

LINKING EVIDENCE TO ACTION

A two-class system for interpreting exercise knowledge among pregnant women is statistically supported. We believe that this study has evidence-based potential to help healthcare providers improve pregnant women's exercise knowledge as part of routine prenatal care to promote exercise.

Targeting the perinatal diet to modulate the gut microbiota increases dietary variety and prebiotic and probiotic food intakes: results from a randomised controlled trial

OBJECTIVE

To evaluate the hypothesis that a perinatal educational dietary intervention focused on 'eating for the gut microbiota' improves diet quality of pregnant women pre- and postnatally.

DESIGN

The Healthy Parents, Healthy Kids study is a prospectively registered randomised controlled trial designed to evaluate the efficacy of a dietary intervention in altering the maternal and infant gut microbiota and improving perinatal diet quality. Eligible pregnant women were randomised to receive dietary advice from their healthcare provider or to additionally receive a three session dietary intervention. Dietary data were collected at gestation weeks 26, 31, 36 and postnatal week 4. Outcome measures were diet quality, dietary variety, prebiotic and probiotic food intakes, energy, fibre, saturated fat and discretionary food intakes. Between-group differential changes from baseline before and after birth in these dietary measures were assessed using generalised estimating equations.

SETTING

Melbourne, Australia.

PARTICIPANTS

Healthy pregnant women from gestation week 26.

RESULTS

Forty-five women were randomised (twenty-two control, twenty-three intervention). Compared with the control group, the intervention group improved diet quality prior to birth (5·66 (95 % CI 1·65, 9·67), Cohen's d: 0·82 (se 0·33)). The intervention improved dietary variety (1·05 (95 % CI 0·17, 1·94), d: 0·66 (se 0·32)) and increased intakes of prebiotic (0·8 (95 % CI 0·27, 1·33), d: 0·91 (se 0·33)) and probiotic foods (1·05 (95 % CI 0·57, 1·53), d: 1·3(se 0·35)) over the whole study period compared with the control group.

CONCLUSION

A dietary intervention focused on 'eating for the gut microbiota' can improve aspects of perinatal diet quality during and after pregnancy.

Guideline No. 391-Pregnancy and Maternal Obesity Part 1: Pre-conception and Prenatal Care

OBJECTIVE

This guideline will review key aspects in the pregnancy care of women with obesity. Part I will focus on pre-conception and pregnancy care. Part II will focus on team planning for delivery and Postpartum Care.

INTENDED USERS

All health care providers (obstetricians, family doctors, midwives, nurses, anaesthesiologists) who provide pregnancy-related care to women with obesity.

TARGET POPULATION

Women with obesity who are pregnant or planning pregnancies.

EVIDENCE

Literature was retrieved through searches of Statistics Canada, Medline, and The Cochrane Library on the impact of obesity in pregnancy on antepartum and intrapartum care, maternal morbidity and mortality, obstetrical anaesthesia, and perinatal morbidity and mortality. Results were restricted to systematic reviews, randomized controlled trials/controlled clinical trials, and observational studies. There were no date or language restrictions. Searches were updated on a regular basis and incorporated in the guideline to September 2018. Grey (unpublished) literature was identified through searching the websites of health technology assessment and related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies.

VALIDATION METHODS

The content and recommendations were drafted and agreed upon by the authors. Then the Maternal-Fetal Medicine Committee peer reviewed the content and submitted comments for consideration, and the Board of the Society of Obstetricians and Gynaecologists of Canada (SOGC) approved the final draft for publication. Areas of disagreement were discussed during meetings, at which time consensus was reached. The level of evidence and quality of the recommendation made were described using the Evaluation of Evidence criteria of the Canadian Task Force on Preventive Health Care.

BENEFITS, HARMS, AND COSTS

Implementation of the recommendations in these guidelines may increase obstetrical provider recognition of the issues affected pregnant individuals with obesity, including clinical prevention strategies, communication between the health care team, the patient and family as well as equipment and human resource planning. It is hoped that regional, provincial and federal agencies will assist in the education and support of coordinated care for pregnant individuals with obesity.

GUIDELINE UPDATE

SOGC guidelines will be automatically reviewed 5 years after publication. However, authors can propose another review date if they feel that 5 years is too short/long based on their expert knowledge of the subject matter.

SPONSORS

This guideline was developed with resources funded by the SOGC.

MAMMA MIA! Norwegian Midwives' Practices and Views About Gestational Weight Gain, Physical Activity, and Nutrition

Objectives

Most studies regarding prevalence of prenatal lifestyle counseling are based on patient report of provider advice. The aim of the present study was to describe midwives' practice and views in promoting three distinct, but importantly related lifestyle factors: gestational weight gain (GWG), regular physical activity (PA), and nutrition.

Design

A cross-sectional study.

Setting

Healthcare clinics in Oslo and Akershus County, Norway.

Participants

Clinics that expressed interest to participate provided an email list of the midwives. Of 107 midwives invited to participate, 65 completed the 15-min electronic survey (SurveyXact), giving a response rate of 60.7%.

Outcome Measures

We developed a new questionnaire based on questions and results from similar studies, as no validated questionnaires existed when we initiated this project in 2014. The final electronic questionnaire included a mix of close-ended questions, semi-close-ended questions, and 11-point Likert scales and covered demographics, personal health behaviors, counseling practice, views, and self-perceived role in lifestyle counseling.

Results

Mean workload in prenatal care was 78%, and mean years practicing was 8.9 (±7.5). Across all three health topics, most (74-95%) reported to give advice on the first meeting, with a mean frequency of 2.2 (±1.4), 2.7 (±1.8), and 2.7 (±2.0) for GWG, PA, and nutrition counseling, respectively. Approximately 40% did not report advice on GWG or give advice discordant with the Institute of Medicine (IOM) recommendations (2009) for at least one prepregnancy body mass index (BMI) category. GWG was rated as more unpleasant to talk about than PA (3.0 ± 2.8 vs. 1.1 ± 2.5, p < 0.001) and nutrition (3.0 ± 2.8 vs. 1.2 ± 2.5, p = 0.002). Also, regarding the importance of giving lifestyle advice, PA (9.6 ± 0.9 vs. 8.3 ± 2.2, p < 0.001) and nutrition (9.9 ± 0.4 vs. 8.3 ± 2.2, p < 0.001) were rated as more important than advice about GWG. Postpartum, nearly 40% gave advice about PA, whereas only two (3.1%) reported to discuss weight/weight retention (p < 0.001).

Conclusion

While most midwives gave advice on GWG, PA, and nutrition at the first meeting and rated lifestyle counseling as an important topic, the advice on GWG was often discordant with IOM recommendations, and the topic was viewed as more unpleasant to talk about than PA and nutrition.

The Relationship Between Pregnancy Intentions and Diet or Physical Activity Behaviors in the Preconception and Antenatal Periods: A Systematic Review and Meta-Analysis

INTRODUCTION

Healthy preconception and antenatal diet and physical activity behaviors may optimize maternal and offspring outcomes. These behaviors are thought to be linked to pregnancy intentions. The aim of this study was to conduct a systematic review and meta-analysis to determine the association between women's pregnancy intentions and diet or physical activity behaviors in the preconception and antenatal periods.

METHODS

MEDLINE Complete, PsycINFO, CINAHL Complete, Global Health, Embase, and INFORMIT: Health Subset were searched in September 2018 for studies that evaluated relationships between pregnancy intentions and dietary and physical activity behaviors. Risk of bias was assessed, and random effects meta-analyses were conducted for dietary (food groups; energy and macronutrients; diet quality; and caffeine, iodine, and folate intake) and physical activity outcomes.

RESULTS

Of 2623 screened records, 19 eligible studies were identified. The overall risk of bias was moderate to high. Twelve studies measured diet and physical activity behaviors during preconception, 5 during pregnancy, and 2 across both periods. Eleven studies measured pregnancy intention retrospectively, and 8 prospectively measured pregnancy intention. The number of studies available for meta-analyses of individual dietary and physical activity outcomes ranged from 2 to 5. Pregnancy intentions were not associated with preconception fruit, vegetable, or caffeine intake or physical activity. Antenatally, women with intended pregnancies were more likely to report healthier diets, lower caffeine intake, and higher physical activity. Insufficient studies were available to conduct subgroup comparisons for prospective or retrospective assessment.

DISCUSSION

Pregnancy intentions were not associated with preconception diet or physical activity behaviors. In contrast, antenatally, women with intended pregnancies demonstrated better diet and physical activity behaviors. Given the small number of studies available for meta-analyses, further research is needed to consolidate our findings. Meanwhile, health professionals can assess women's pregnancy intentions during preconception and pregnancy and encourage a healthy lifestyle.

Content Validation through Expert Judgement of an Instrument on the Nutritional Knowledge, Beliefs, and Habits of Pregnant Women

The aim of this study was to conduct content validation through expert judgement of an instrument which explores the nutritional knowledge, beliefs, and habits during pregnancy. This is a psychometric study in which 14 experts participated in the evaluation of each of the questionnaire items, which were divided into two blocks according to the characteristics of sufficiency, clarity, coherence, and relevance. Fleiss’ κ statistic was used to measure strength of agreement. A pre-test with 102 participants was conducted to measure the degree of understandability of the instrument. The strength of agreement obtained for each of the dimensions was almost perfect. For each pair of experts, strength of agreement ranged between substantial and almost perfect. Sufficiency was the characteristic of the questionnaire that obtained the highest values in the two blocks, and was also the most statistically significant (p < 0.001). Coherence was the most statistically significant characteristic in the first block (p = 0.030). Clarity was the most statistically significant characteristic in the second block (p = 0.037). The wording of five of the twenty original items was corrected. The new version of the instrument attained a high degree of understandability. The results suggest that the instrument is valid and may therefore be applied.

Body mass index of women in Bangladesh: comparing Multiple Linear Regression and Quantile Regression

This study explored the association between socio-demographic factors and the body mass index (BMI) of women of reproductive age (15–49 years) in Bangladesh. Data from the 2014 Bangladesh Demographic and Health Survey (BDHS-14) were analysed using Multiple Linear Regression (MLR) and Quantile Regression (QR) analyses. The study sample comprised 15,636 non-pregnant women aged 15–49. The mean BMI of the women was 22.35±4.12 kg/m2. Over half (56.75%) had a BMI in the normal range (18<BMI<25 kg/m2), and 18.50%, 20.00% and 4.75% were underweight (BMI≤18 kg/m2), overweight (25≤BMI<30 kg/m2) and obese (BMI≥30 kg/m2), respectively. The results of the MLR found that age, wealth index, urban/rural place of residence, geographical division, womenʼs educational status, husbandʼs educational status, womenʼs working status and total number of children ever born were significantly (p<0.001) associated with respondents’ mean BMI. The QR results showed different associations between socio-demographic factors and mean BMI, as well as a different conditional distribution of mean BMI. Overall, the results indicated that women with uneducated husbands, with little or no education and from less-affluent households from rural areas tended to be more underweight compared with women in other groups. The inter-relationship between the study womenʼs mean BMI and associated socio-demographic factors was assessed using QR analysis to identify the most vulnerable cohorts of women in Bangladesh.
