Be Healthy in Pregnancy: Exploring factors that impact pregnant women's nutrition and exercise behaviours

"I have not been doing it because of my fear of something happening." Exploring perspectives on healthy dietary behaviors and physical activity in Mexican pregnant women and health care professionals: A qualitative study

OBJECTIVES

Mexico exhibits one of the highest prevalence rates of overweight and obesity globally, accompanied by a surge in non-communicable diseases, which in turn leads to elevated mortality rates. Existing efforts to address rising obesity rates have shown limited effectiveness. Maternal weight, diet, and physical activity (PA) during pregnancy affect the mother's and offspring's health. Despite the importance of establishing and engaging in healthy behaviors during pregnancy, little is known about which factors impact these behaviors among pregnant women in Mexico. This study explored perspectives on factors impacting healthy dietary behaviors and PA in pregnancy from pregnant women and health care professionals in Mexico.

METHODS

We conducted semistructured interviews with 11 pregnant women and 12 health care professionals working in prenatal care. Data were analyzed using qualitative content analysis in a stepwise inductive approach.

RESULTS

Classifying factors at the 1) individual level, 2) relational level, and 3) health care system level, three overall themes emerged. At the individual level, challenges with lack of time and competing priorities as well as knowledge of healthy dietary behaviors and PA were identified. At the relational level, influencing factors encompassed financial, social, and emotional support along with descriptive norms. At the health care system level, guidelines for PA during pregnancy and the quality of care were noted.

CONCLUSIONS

This study identified factors impacting healthy dietary behaviors and PA in pregnancy in Mexico. Important considerations for future interventions include addressing sociocultural norms around healthy dietary behaviors and PA in pregnancy and involving pregnant women's families, closest social networks, and health care professionals working at the prenatal care unit.

Current status and influencing factors of protective motivation for body mass management during pregnancy

OBJECTIVE

Excessive weight gain, obesity, or insufficient weight gain during pregnancy can adversely affect both the mother and her offspring. This study aims to investigate the relationship between pregnant women's self-perception and beliefs and their body weight management during pregnancy.

METHODS

A cross-sectional survey involving 350 pregnant women in Changsha City was conducted from July to September 2023. Instruments included a sociodemographic data sheet, protective motivation questionnaire for pregnancy body quality management, and scales measuring body image, anxiety, self-efficacy, and social support. Univariate analysis and multiple linear regression were employed to identify factors influencing protective motivation for body quality management during pregnancy.

RESULTS

The average score of the protective motivation questionnaire was 124 (SD = 13.07), suggesting a need for enhanced weight management. Key factors influencing protective motivation included household income, cooperation with healthcare workers, sources of pregnancy information, midnight snacking habits, prepregnancy exercise, body image, and self-efficacy (P < 0.05).

CONCLUSION

The study highlights significant factors influencing pregnant women's motivation for body quality management. These include economic status, healthcare collaboration, information accessibility, lifestyle habits, and psychological factors. The findings underscore the need for healthcare professionals to integrate these factors into pregnancy care programs to improve body quality management.

[Review of nutrition and hydration in relation to physical exercise during pregnancy]

Introduction

Studies on nutritional recommendations for pregnant women who exercise are scarce. The objective of this article is not to focus on the diet of pregnant women as a whole, but to review those aspects of it that may be related to physical exercise. To this end, the nutritional and hydration recommendations contained in the main clinical practice guides on physical exercise during pregnancy are collected, including the first Spanish guides. Likewise, the energy requirements required by pregnant women who perform physical exercise during pregnancy for adequate gestational weight gain are addressed, aspects related to macronutrients in the aforementioned population group, and two specific topics, such as nutritional needs in the adolescent who practices physical exercise during pregnancy and eating disorders in pregnant athletes It is concluded by stating that pregnant women who exercise regularly should eat a varied and balanced diet, such as the Mediterranean diet, avoid long periods of fasting to avoid the appearance of hypoglycemia and maintain adequate fluid intake before, during and after physical exercise. Pregnant adolescents who engage in physical exercise require nutritional supervision to achieve adequate gestational weight gain. The pregnant athlete with an eating disorder has a higher risk of complications during pregnancy and childbirth, gynecological, fetal and neonatal, and, therefore, requires close monitoring by specialists in maternal-fetal medicine.

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.

Assisted reproductive technology and physical activity among Chinese pregnant women at high risk for gestational diabetes mellitus in early pregnancy: A cross-sectional study

Currently, the number of pregnant women at high risk for gestational diabetes mellitus (GDM) and using assisted reproductive technology (ART) is increasing. The present study aims to explore the relationship between ART and physical activity in Chinese pregnant women at high risk for GDM in early pregnancy. A cross-sectional study was conducted in a regional teaching hospital in Guangzhou, China, between July 2022 and March 2023. Three hundred fifty-five pregnant women at high risk for GDM in early pregnancy completed the Chinese version of the Pregnant Physical Activity Questionnaire (PPAQ), the Pregnancy Physical Activity Knowledge Scale, the Pregnancy Physical Activity Self-Efficacy Scale, the Pregnancy Physical Activity Social Support Scale, and a sociodemographic and obstetric characteristics data sheet. Compared to women who conceived naturally, women who used ART were more likely to be 35 years or older, unemployed, primigravidae, and to have intentionally planned their pregnancies. Women who used ART had significantly lower levels of physical activity and self-efficacy compared to their counterparts who conceived naturally. Over half (55.6%) of women who used ART reported being physically inactive, and those with lower self-efficacy, as well as the unemployed, were significantly more likely to be inactive. Physical inactivity is a critical clinical issue among women who use ART, especially in the context of GDM risk. Future research should develop and test physical activity programs, including enhancing physical activity self-efficacy for women who use ART. Patient or public contribution: In this study, survey questionnaires were completed by participants among Chinese pregnant women at high risk for GDM in early pregnancy.

Theory-based interventions aimed at promoting physical activity in pregnant women: A systematic review and meta-analysis of randomized controlled trials

OBJECTIVES

The objectives were to assess (i) the quality of theory implementation, (ii) the application of behavior change techniques, and (iii) the effectiveness of theory-based interventions in promoting physical activity in pregnant women and improving maternal and neonatal outcomes.

METHODS

A systematic search was conducted across 8 databases (Cumulative Index to Nursing and Allied Health Literature, the Cochrane Library, EMBASE, MEDLINE, APA PsycINFO, PubMed, SPORTDiscus, and Web of Science) to identify randomized controlled trials published from database inception to 8 July 2023. The Cochrane risk-of-bias 2.0 tool was used to evaluate the quality of the included studies. The theory coding scheme was used to measure the quality of theory implementation, and behavior change techniques were coded according to behavior change taxonomy (version 1). The meta-analysis was performed using RevMan 5.3. The Grading of Recommendations, Assessment, Development, and Evaluation Approach was used to assess the certainty of evidence.

RESULTS

Eleven studies met the study criteria. Nine studies were based on one theory, while two studies were based on a combination of two theories. The quality of theory implementation was generally moderate. A total of 24 unique behavior change techniques were extracted. The most commonly used types of behavior change techniques were 'instruction on how to perform the behavior' (n = 9), 'goal setting' (behavior) (n = 8), 'action planning' (n = 7), and 'information about health consequences' (n = 7). Theory-based interventions significantly improved moderate-to-vigorous physical activity (standardized mean difference (SMD) = 0.17, 95 % confidence interval (CI) [0.04, 0.30], P = 0.01; moderate certainty of evidence), reduced the average gestational weight gain per week (mean difference (MD) = -0.06, 95 % CI [-0.11, -0.01], P = 0.02; moderate certainty of evidence), and decreased the incidence of gestational diabetes mellitus (risk ratio (RR) = 0.64, 95 % CI [0.46, 0.89], P = 0.008; high certainty of evidence). However, the effects of theory-based interventions on total physical activity, total gestational weight gain and the incidence of gestational hypertension and preterm delivery were unclear (P > 0.05).

CONCLUSIONS

(i) Most of the studies exhibited a moderate level of theory implementation quality. (ii) The use of theories varies, but common behavior change techniques were found across studies. (iii) Theory-based interventions can improve physical activity and maternal and neonatal outcomes and appear to be safe. Appropriate health behavior theories and behavior change techniques should be fully utilized in future interventions.

TWEETABLE ABSTRACT

Theory-based interventions can improve physical activity and maternal and neonatal outcomes and appear to be safe. Appropriate health behavior theories and behavior change techniques should be fully utilized in the development of future interventions.

Experiences accessing nutritious foods and perceptions of nutritional support needs among pregnant and post-partum mothers with low income in the United States

Access to nutritious foods, a social determinant of health, contributes to disparities in maternal and infant health outcomes such as mental health, breastfeeding intensity and cardiometabolic risk. This study explored perceived nutrition access and intake among pregnant or post-partum women eligible for Medicaid. Qualitative, semistructured interviews were conducted with 18 women who were either currently pregnant (n = 4) or up to 12 months post-partum (n = 14) in 2021-2022. Mothers spoke English (n = 11) or Spanish (n = 7) and lived in the Texas Panhandle. Interviews were audio-recorded, transcribed, translated (Spanish to English) and verified. Two or more researchers coded each interview until consensus was reached using thematic analysis with ATLAS.ti software. The study revealed five drivers for nutrition access. (1) Social factors influenced nutrition; those with less support expressed limited ability to eat healthfully. (2) The Women, Infants and Children program was perceived as a helpful resource for some, while others faced challenges obtaining it. (3) Stress was bidirectionally related to unhealthy food choices, with food sometimes used as a coping mechanism. (4) Mothers prioritized their babies and others and had limited ability and time to prepare healthy meals. (5) Most participants felt they received inadequate nutrition guidance from their healthcare providers. Participants provided positive responses to a proposed nutritious home-delivered meal intervention. Low-income women may experience nutritional challenges specific to this life stage. Interventions that reduce stress and burden of household tasks (e.g. cooking) and improve education and access to nutritious foods may improve mothers' ability to consume nutritious foods.

A Fresh Fruit and Vegetable Prescription Program for Prenatal Patients in Flint, Michigan: Baseline Food Security and Dietary Intake

Although adequate nutritional status during pregnancy is necessary to support optimal fetal development, many low-income women have poor access to fresh, high-nutrient foods. To address these challenges, a pediatric fruit and vegetable (FV) prescription program was expanded to include pregnant women, providing one prescription for fresh FVs worth 15 US dollars during each prenatal office visit for redemption at farmers'/mobile markets. This analysis describes baseline sociodemographic characteristics, food security, and dietary intake among 253 pregnant women in Flint, Michigan in 2022-23. Dietary recall data were collected and analyzed using the Automated Self-Administered 24-h Tool developed by the US National Cancer Institute, with nutrition output reported in relation to adherence to US Dietary Guidelines. Most participants (mean ± SD age 26.51 ± 4.90 years) identified as African American (53%) and were receiving publicly funded health insurance (66%). Most (75%) reported no food insecurity, yet the majority failed to meet dietary recommendations for whole grains (99.3%), vegetables (93.1%), dairy (93.1%), and fruits (69.4%). Moreover, most did not meet micronutrient recommendations through food sources, including vitamin D (100%), iron (98.6%), folic acid (98.6%), vitamin A (82.6%), calcium (68.8%), and vitamin C (62.5%). Results raise deep concerns regarding diet and nutrition among pregnant women in this US city.

Could commercial meal kits be part of the solution to food insecurity during pregnancy? An Australian exploratory study

AIM

To explore the nutritional content of meal kits from two main Australian companies over a 6-week period against healthy eating guidelines for pregnancy.

METHOD

Across the 6-week period, weekly meal kits from both Provider 1 and Provider 2 were purchased, 36 individual meals were assessed. All data were analysed for the development of a macronutrient and micronutrient profile of meals. Extracted data were macronutrient, vitamin, and mineral composition, which were compared against the healthy eating guidelines for pregnant women in Australia and New Zealand.

RESULTS

Meal kits include higher levels of sodium, and lower levels of dietary fibre, calcium, magnesium, zinc, iron, thiamin, riboflavin, grains, and dairy when compared against the guidelines for healthy eating for pregnant women in Australia and New Zealand.

CONCLUSIONS AND IMPLICATIONS

Meal kits may increase meals prepared and consumed in the home, and thanks to the clear instructions and pre-portioned ingredients, may reduce stress related to food preparation. They have the potential to provide nutritionally adequate meals to pregnant women as a way to mitigate food insecurity or hunger during pregnancy and may provide some nutritional benefits and have the potential to remove some of the challenges with maintaining an adequate diet when pregnant.

Predictors of physical inactivity among pregnant women

It is recommended that pregnant women be physically active to promote maternal and child health. This study aimed to explore the prevalence of physical inactivity and its modifiable predictors in the three trimesters in Chinese pregnant women. Four hundred forty-four pregnant women completed the Pregnant Physical Activity Questionnaire in the first, second, and third trimesters. The prevalence of physical inactivity reached its highest (66.2%) in the first trimester and lowest (19.4%) in the second trimester. Pregnant women with inadequate physical activity knowledge and low self-efficacy were at higher risk for physical inactivity. Monitoring physical inactivity could be incorporated into antenatal care and start from the first trimester. Prenatal care professionals should take action to increase pregnant women's physical activity self-efficacy and knowledge to enhance their physical activity.

Determinants of Physical Activity Among Black Women During Pregnancy

OBJECTIVE

To describe associations among background determinants of physical activity, modifiable theoretical determinants of physical activity, and measures of physical activity during the second and third trimesters of pregnancy among Black women.

DESIGN

Longitudinal cohort.

SETTING

Medical center obstetric clinic.

PARTICIPANTS

Pregnant Black women (n = 40 in second trimester, n = 38 in third trimester) METHODS: We measured background determinants (demographic and pregnancy characteristics, discrimination, and neighborhood walkability) during the second trimester. We measured modifiable theoretical determinants (self-efficacy and social support) and physical activity using self-report and device measures during the second and third trimesters. We used paired t tests to determine differences in the modifiable theoretical determinants from the second trimester to third trimester and used Pearson correlations among background and modifiable determinants and physical activity measures during the second trimester.

RESULTS

Participants' physical activity levels were low during the second and third trimesters (32% and 22% met recommendation, respectively). We found no changes in self-efficacy or social support between trimesters and found no associations between these modifiable determinants and actual physical activity. We found a positive correlation between previous pregnancies and physical activity measured by devices, r(36) = .33, p = .048. Pregnancy-specific stress, r(38) = -.40, p = .013, was negatively correlated, and age, r(38) = .38, p = .017, was positively correlated with self-reported physical activity.

CONCLUSIONS

Low levels of physical activity during pregnancy coupled with the absence of an association with modifiable factors affecting pregnancy physical activity indicate a need to further examine the social, cultural, and environmental determinants of physical activity.

The knowledge, attitudes, and behaviours of pregnant women regarding seafood consumption during the antenatal period: a qualitative study

BACKGROUND

Maternal nutrition impacts fetal growth and development. The Food Standards Australia New Zealand (FSANZ) guidelines recommend pregnant women consume 2-3 servings (224-336 g) of fish/seafood per week to support intake of long chain omega 3 fatty acids, given adequate consumption supports numerous health benefits including reduced risk of preterm and early preterm birth. Evidence indicates that pregnant women purposely lower their fish/seafood intake, largely due to fears of methylmercury exposure. The aim of this study was to explore pregnant women's knowledge, attitudes, and behaviours regarding their fish/seafood consumption during the antenatal period.

METHODS

Semi-structured interviews were conducted between October 2018 and December 2020 among a purposive sample of 12 pregnant women from the Australian Capital Territory (ACT). The interviews were recorded, transcribed verbatim, and analysed using an interpretative phenomenological approach. Themes were developed on the women's lived experience related to fish/seafood knowledge, attitudes, and consumption behaviour.

RESULTS

The most prominent finding was widespread non-adherence to fish/seafood consumption guidelines. This was largely owing to a lack of proactive health promotion related to the health benefits of fish/seafood throughout pregnancy, including the health promoting roles of long chain omega 3 fatty acids for fetal growth and development. Three themes were identified: nutrition knowledge; sources of health promotion; and barriers and enablers to fish/seafood consumption.

CONCLUSIONS

To support adequate maternal consumption of fish/seafood throughout pregnancy, emphasis should be placed on the benefits of consuming this food group regularly. Additionally, pregnant women should receive education about the health promoting role of long chain omega 3 fatty acids. Dietitians are well placed to provide this information.

Mango Consumption Was Associated with Higher Nutrient Intake and Diet Quality in Women of Childbearing Age and Older Adults

Nutritional equity has been recognized as a priority in nutrition research, as reiterated by the new life-stage approach utilized by the Dietary Guidelines for Americans. Two of the life stages focused on are pregnant and lactating females as well as older adults, due to their unique nutritional needs and unique chronic health conditions. Both groups have low intakes of several nutrients, including those of public health concern, and suboptimal diet quality, underlining the importance to improve their dietary intakes. Incorporating fruit into their diets could help alleviate these gaps. Thus, the objective of the current study is to expand upon our current knowledge of the benefits of fruit within these two subgroups that DGA guidelines focus on and determine nutrient and food group intake as well as diet quality in women of childbearing age (WCA; as a proxy for pregnant and/or lactating females, n = 16,774) and older adult (n = 18,784) mango consumers compared with non-consumers, using NHANES 1988-1994 and 1999-2018. Both WCA and older adult mango consumers had greater than 20% higher intakes of fiber and vitamin C and WCA consumers had upwards of 10% higher folate, magnesium, and potassium intakes compared with non-consumers. Both groups of consumers had lower intake of saturated fat and older adults had lower intakes of protein and vitamin B12. Diet quality was 16 and 13% higher in WCA and older adult consumers compared with non-consumers, respectively. Additionally, mango consumers had lower beef, poultry, fish, and solid fat intakes and WCA consumers had higher whole grain intakes compared with non-consumers. This study suggests incorporating mango into the diet could increase select nutrient intake as well as diet quality in specific life stages of adult Americans.

Effects of a Comprehensive Dietary Intervention Program, Promoting Nutrition Literacy, Eating Behavior, Dietary Quality, and Gestational Weight Gain in Chinese Urban Women with Normal Body Mass Index during Pregnancy

In urban Chinese women with normal body weight during pregnancy, we implemented a comprehensive dietary intervention program aimed at enhancing nutrition literacy, dietary quality, and gestational weight gain. The methods included both online and offline health education on prenatal nutrition, weekly weight monitoring, family back education practices, and real-time dietary guidance. The intervention was delivered to randomly assigned control and intervention group participants from gestational week 12 to week 24. The intervention group (n = 44; 100% complete data) showed significant differences (mean (SD)) compared to the control group (n = 42; 95.5% complete data) in nutrition literacy (53.39 ± 6.60 vs. 43.55 ± 9.58, p < 0.001), restrained eating (31.61 ± 7.28 vs. 28.79 ± 7.96, p < 0.001), Diet Quality Distance (29.11 ± 8.52 vs. 40.71 ± 7.39, p < 0.001), and weight gain within the first 12 weeks of intervention (4.97 ± 1.33 vs. 5.98 ± 2.78, p = 0.029). However, there was no significant difference in the incidence of gestational diabetes (2 (4.5%) vs. 4 (9.5%), p = 0.629). Participants in the intervention group reported an overall satisfaction score of 4.70 ± 0.46 for the intervention strategy. These results emphasize the positive role of comprehensive dietary intervention in promoting a healthy diet during pregnancy.

Lipid-focused dietary education intervention in pregnant women: study protocol for an open-label, parallel, randomised, intervention study addressing adverse pregnancy outcomes in China

INTRODUCTION

The incidence of infants who are large-for-gestational-age (LGA) is on the rise in China, and its detrimental effects on health have received increasing attention. Diet-based interventions have the potential to reduce adverse birth outcomes, particularly in decreasing the occurrence of LGA infants. We aim to evaluate the effect of lipid-focused diet education based on the theories of behaviour change in pregnant women on maternal and offspring outcomes through a randomised controlled trial.

METHODS AND ANALYSIS

We have designed an open-label, parallel, multicentre randomised controlled trial in collaboration with three hospitals in Beijing, China.Pregnant women will be recruited before reaching 12 weeks of gestation and will be randomised in a 1:1:1 ratio into three arms: (1) online education arm, (2) pregnancy nutrition checklist and 'one-page flyer' arm and (3) routine antenatal education. The primary outcome LGA will be recorded at birth. Demographic information, physical activity, sleep and medical history will be collected through questionnaires and case cards prior to enrolment. Questionnaires will also be used to collect dietary behaviours and psychosocial factors of pregnant women at enrolment, at 24-28 weeks and 34-36 weeks of gestation. Additionally, information on breastfeeding and complementary food supplementation for infants and young children will be obtained through questionnaires. Physical development indicators of children and taste tests will be assessed 3 years after delivery.

ETHICS AND DISSEMINATION

The study has received ethical approval from the Capital Medical University Ethics Committee and other collaborating study centres. Informed consent will be introduced to pregnant women, and their consent will be obtained. The findings will be reported in relevant national and international academic conferences and peer-reviewed publications.

Increased consumption of ultra-processed foods during pregnancy is associated with sociodemographic, behavioral, and obstetric factors: A cohort study

A diet based on ultra-processed food (UPF) does not meet nutritional needs, especially during pregnancy. The aim of this study is to assess the change in UPF consumption from preconception to pregnancy and associated factors. Our hypothesis is that women tend to adopt a healthier eating pattern during pregnancy, decreasing the intake of UPF and increasing the intake of unprocessed/minimally processed foods. A prospective cohort study with 326 participants was carried out from 2016 to 2019 in 2 health units in Rio de Janeiro, Brazil. Pregestational food consumption assessed using the food frequency questionnaire in the prenatal interview in women up to 20 gestational weeks and gestational consumption in the interview 2 months after delivery. Food items classified according to the NOVA system. For the mean variation from preconception to gestational UPF consumption, we used the generalized estimating equations model with linear distribution. Control of confounding variables was based on the literature on factors associated with UPF consumption, using a 3-level hierarchical model. The proportion of UPF energy consumption was 28.9% in preconception and 33% during pregnancy. Older and more educated women had a lower mean variation in the consumption of UPF during the pregnancy. A higher average consumption of UPF observed among women physically inactive before pregnancy, who smoked during pregnancy, were multiparous, and with had a low pregestational weight. These results reflect similar behavior to that of the general population, aggravated by a significant increase during pregnancy. However, older and more educated women and those with healthy behaviors showed lower UPF intake in 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.

Evidence-Based Eating Patterns and Behavior Changes to Limit Excessive Gestational Weight Gain: A Scoping Review

BACKGROUND

International prenatal care guidelines set a standard for clinicians to discuss gestational weight gain with their patients along with the complications associated with prepregnancy obesity and excessive gestational weight gain. Clinicians often lack evidence-based eating, nutrition, and activity strategies to share with patients.

METHODS

This systematic review aimed to find eating patterns and behaviors that could be used safely during pregnancy to limit excessive gestational weight gain. PubMed, MEDLINE, and Web of Science were searched for research or systematic reviews performed in the United States or Canada and published in English from 2013 to 2023. Keyword search terms included weight, manage, behavior, strategy, strategies, gestational weight gain, and nutrition. Excluded research used pediatric or adolescent populations, restrictive diets, such as no carbohydrate or no fat diets, fasting, bariatric surgery, weight loss medications, private industry or profit-earning programs using food brands, or specific diet programs.

RESULTS

A total of 844 abstracts were retrieved, with 103 full-text studies reviewed. Behaviors had to be useful for maintaining a healthy gestational weight gain and had to be safe for use during pregnancy. Behaviors useful during pregnancy included meal planning, home meal preparation, portion control, using diets such as the Mediterranean diet, the low-glycemic index diet, and the Dietary Approaches to Stop Hypertension diet (DASH), regular physical activity, sleeping 6-7 h a night, mindful eating, intuitive eating, and regular seif-weighing.

CONCLUSION

The evidence-based strategies outlined in this review are safe for use during pregnancy and can assist patients in avoiding excessive gestational weight gain while maintaining the nutrition needed for healthy fetal growth.

Counselling on physical activity in Danish antenatal care: A qualitative study of experiences from both the pregnant woman's and the care provider's perspective

OBJECTIVES

Physical activity during pregnancy is beneficial to maternal and fetal health, but most pregnant women do not achieve the recommended level of physical activity. To investigate how antenatal care can promote physical activity during pregnancy, this study explores experiences of physical activity counselling from the perspectives of pregnant women and antenatal care providers.

METHODS

In a qualitative design with an inductive approach individual semi-structured interviews with 19 pregnant women and seven antenatal care providers were performed and analyzed using thematic analysis.

RESULTS

The themes "Experiencing inadequate counselling", "Benefiting from individualized guidance", and "Voicing a need for enhanced support" cover the perspectives from the participating pregnant women. They often experienced insufficient physical activity counselling that left them insecure about proper physical activity during pregnancy. The pregnant women desired individualized and concrete advice and early and continuous support. From antenatal care providers the themes "Providers' perceived barriers in counselling", "Balancing the act of counselling", and "Acknowledging potential for enhanced counselling" were identified. They perceived barriers towards counselling including time restraints, lack of interest, and doubts about certain physical activity during pregnancy but expressed trying to adjust the counselling to meet the woman's individual situation. They acknowledged that continuous support during pregnancy and updated knowledge and increased focus among providers might improve physical activity counselling.

CONCLUSIONS

Pregnant women received scarce counselling on physical activity in antenatal care, while care providers described several barriers towards counselling on physical activity. Both pregnant women and antenatal care providers recognized opportunities for enhanced physical activity counselling.

Culturally Tailored Strategies for Prenatal Physical Activity for South Asian Women: A Scoping Review

Low levels of physical activity (PA) are reported in South Asian pregnant women. This scoping review summarizes culturally tailored strategies in prenatal PA studies for South Asian women and identifies barriers and facilitators. A search strategy was developed with the keywords "Physical Activity" AND Pregnant AND "South Asian" and was carried out on Medline, SportDiscus, EMBASE, Web of Science and Proquest Theses and Dissertations. Primary research studies were included. Forty-six studies were included of which 40 were from South Asian countries. No interventions were identified outside of South Asian countries. Offering material in different languages was the most common tailoring strategy. Reported barriers were possible social norms favouring inactivity, lack of awareness on safe exercises, and physical symptoms (e.g., fatigue). Facilitators included social support and relief from physical symptoms. Future PA interventions for South Asian pregnant women should account for population-specific barriers and facilitators to increase PA initiation and maintenance.

"The best of a bad situation?" A mixed methods survey exploring patients' perspectives on physiotherapy-led online group exercise programmes

INTRODUCTION

The COVID-19 pandemic saw the migration of many physiotherapy-led group exercise programmes towards online platforms. This online survey aimed to ascertain the patients' views of online group exercise programmes (OGEP), including their satisfaction with various aspects of these programmes, the advantages and disadvantages and usefulness beyond the pandemic.

METHODS

A mixed-methods design was utilised with a cross-sectional national online survey of patients who had previously attended a physiotherapy-led OGEP in Ireland. The survey collected both qualitative and quantitative data. Descriptive statistics were used to summarise the ordinal and continuous data and conventional content analysis was used to analyse the free-text responses.

RESULTS

In total, 94 patients completed the surveys. Fifty percent of patients questioned would prefer in-person classes. Despite only a quarter of patient respondents preferring online classes going forward, satisfaction with the OGEPs was high with nearly 95% of respondents somewhat or extremely satisfied. Decreased travel and convenience were cited as the main benefits of OGEPs. Decreased social interaction and decreased direct observation by the physiotherapist were the main disadvantages cited.

CONCLUSION

Patients expressed high satisfaction rates overall with online classes, but would value more opportunities for social interaction. Although 50% of respondents would choose in-person classes in the future, offering both online and in-person classes beyond the pandemic may help to suit the needs of all patients and improve attendance and adherence.

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.

A socio-ecological model of factors influencing physical activity in pregnant women: a systematic review

Physical activity (PA) is safe for most pregnant women, improving both maternal fitness and birth outcomes. Despite evidence of benefits, most pregnant women eliminate or reduce PA during pregnancy. This systematic review aimed to analyze the factors affecting maternal PA during pregnancy with reference to a socio-ecological model. A systematic search of relevant published studies between 2001 and 2022 was conducted through PubMed, Scopus, Web of Science, Academic Search Ultimate, Medline, and SPORTDiscus with full text via the EBSCO platform. A total of 32 studies that met the inclusion criteria were reviewed. The findings revealed that various study designs can lead to different outcomes in terms of what is identified as a PA facilitator or barrier. The factors that positively influenced PA in pregnant women were: higher levels of education, knowledge, and skills, as well as access to mass media. Conversely, lower levels of education, lack of knowledge and skills, low income, pregnancy discomforts, limited time, safety concerns, and societal perceptions of PA in pregnancy acted as barriers. Additionally, family, colleagues/friends, and partners could either support or hinder PA. Factors affecting overall maternal PA were somewhat different from those affecting the moderate-to-vigorous intensity of PA. Pregnant women receive little organizational and policy support. There is an urgent need to provide accessible information and resource systems for pregnant women. Since most pregnant women are motivated to engage in PA and susceptible to family advice, interventions should not be limited only to pregnant women, but should involve a family member, especially partners. There is a need to take global, systemic actions to promote an active lifestyle in pregnancy. Addressing safety concerns related to PA during pregnancy should be a significant part of these promotional activities.

The role of the partner in the support of a pregnant woman's healthy diet: an explorative qualitative study

BACKGROUND

Active partner involvement during pregnancy is an effective strategy to enhance both maternal and newborn health outcomes. The presence of a supportive partner equips women with a heightened sense of empowerment to deal with the challenges of pregnancy, including maintaining a healthy diet during pregnancy, which is important for the health of both the mother and child. However, little information exists regarding the partner's role in encouraging a pregnant woman's healthy dietary choices. This study aimed to explore the perspectives of pregnant women and their partners concerning the partner's role in promoting a healthy dietary intake during pregnancy.

METHODS

Sixteen semi-structured couple interviews were conducted in the Netherlands, involving expecting couples. Based on Berkman's social networks and support theory, we categorized various forms of support as emotional, instrumental, appraisal, and informational. The interviews were accurately recorded, transcribed verbatim, and analysed using an inductive approach.

RESULTS

In general, pregnant women reported being positive regarding the support they received from their partners. Partners primarily offered instrumental support to pregnant women, such as cooking, grocery shopping, and helping them avoid unsafe foods. Partners provided informational support, mainly about foods considered unsafe during pregnancy. Emotional support was relatively less common. The primary motives for giving support were pregnancy-related symptoms, the importance of the health of the mother and baby, and solidarity with the pregnant woman. Support from the partner was more willingly accepted by pregnant women if the support was perceived as being helpful, showing involvement, and positive. Conversely, partner support was not accepted if it was perceived as judgmental or unwanted.

CONCLUSIONS

The majority of pregnant women were satisfied with the support received from their partners, although there are opportunities for a partner to provide more support to improve the dietary intake of pregnant women. To optimise this support, partners are advised to tailor their support to the needs and expectations of pregnant women. Personalizing dietary support can be achieved by couples communicating their dietary wishes and expectations regarding support.

Predictors of physical activity among Chinese pregnant women during the first trimester: A cross-sectional study

Physical activity during pregnancy has numerous health benefits for the woman and the foetus. The current study investigated physical activity engagement and its predictors among pregnant Chinese women during the first trimester. A total of 687 pregnant women completed the Pregnancy Physical Activity Questionnaire. Bivariate and multivariate logistic regression were used to analyse the data. The current physical activity guidelines were not met by 64.3% of respondents. Women with higher levels of physical activity self-efficacy (aOR = 0.96; 95% CI: 0.92-0.99) and social support (aOR = 0.95; 95% CI: 0.94-0.97) had lower odds of not meeting the current physical activity guidelines. Women who were aged < 35 years (aOR = 1.85; 95% CI: 1.02-3.34), had lower education (aOR = 1.63; 95% CI: 1.04-2.55), were primiparous (aOR = 11.03; 95% CI: 6.98-17.44), were unsure of their delivery mode (aOR = 2.32; 95% CI: 1.95-5.64), and those who had higher levels of pregnancy-associated discomfort (aOR = 1.10; 95% CI: 1.03-1.19) had higher odds of not meeting the current physical activity guidelines. The current study suggests that healthcare professionals should assess physical activity engagement during routine antenatal care and increase efforts to strengthen pregnant women's self-efficacy and social support to promote physical activity engagement during the first trimester.

Maternal Physical Activity Patterns in the 2015 Pelotas Birth Cohort: From Preconception to Postpartum

BACKGROUND

Motherhood has been associated with reduced leisure-time physical activity (LTPA) levels. We aim to assess maternal LTPA patterns from preconception to 4 years postpartum.

METHODS

The study was developed with mothers from the Pelotas 2015 Birth Cohort, Southern Brazil (n = 4273). LTPA data were self-reported for preconception, antenatal, and 3, 12, 24, and 48 months postpartum. Information on LTPA referring to preconception (3 mo before pregnancy) and each gestational trimester was retrospectively collected in perinatal. The prevalence of active mothers was calculated according to recommendations (≥150 min/wk). We described changes in LTPA between follow-ups and estimated the probability of mothers being active according to previous LTPA. We used group-based trajectory analysis to identify patterns of LTPA throughout the follow-ups.

RESULTS

The prevalence of active mothers during leisure time decreased in pregnancy and postpartum compared with preconception. At 12 months postpartum, LTPA levels rose again, but at 48 months, the rates of active mothers still had not returned to preconception levels. Prior LTPA engagement was an important determinant of the maintenance of LTPA. Trajectory analysis identified 4 patterns of maternal LTPA, and ∼80% of mothers were allocated to the "always inactive" group. Higher education and income, working outside the home, multiple births, and participating in the PAMELA study intervention were associated with a higher probability of mothers not being included in this predominantly inactive group.

CONCLUSIONS

Motherhood is associated with declining rates of women meeting physical activity recommendations during pregnancy and early postpartum.

Reliability and validity of the Turkish version of the pregnancy exercise self-efficacy scale

OBJECTIVE

The aim of this study was to adapt the Pregnancy Exercise Self-Efficacy Scale (P-ESES) into Turkish, investigate its reliability and validity in Turkish pregnant women, and obtain a validated tool in order to assess the exercise self-efficacy during pregnancy.

METHODS

A total of 138 pregnant women participated in the present study. For the translation of the P-ESES into Turkish (P-ESES-T), a six-phase process was followed. The psychometric properties of the P-ESES-T were analyzed in respect of internal consistency, test-retest reliability, and criterion validity. To assess the validity of the P-ESES-T, the associations between the P-SES-T and the Pregnancy Physical Activity Questionnaire (PPAQ), the Sensewear Pro3 Armband (n = 31), and the Exercise Barries/Benefits Scale (EBBS) were analyzed.

RESULTS

Test-retest reliability for the P-ESES-T total score was found to be very strong (ICCs: 0.986, p < 0.001). Cronbach's α coefficient was 0.899. There were strong correlations between the total scores of the P-ESES-T and PPAQ, and EBBS (r = 0.780, r = 0.874; p < 0.001). However, no significant correlations were found between the total number of steps and energy expenditure obtained from the physical activity monitor and the P-ESES-T (p > 0.05).

CONCLUSION

The P-ESES-T is a reliable and valid tool that can be used to evaluate exercise self-efficacy, which is an important factor that affects exercise participation during pregnancy.

Assessing Health Care Providers' Knowledge and Practices of Nutrition during Pregnancy in Lebanon: A Cross-Sectional Study

Background and objectives: Health care professionals (HCPs) are well-positioned to discuss healthy behaviors during pregnancy, but the published research of prenatal healthcare providers' knowledge about the significance of nutrition during pregnancy in Lebanon is scarce. The purpose of this study was to explore the knowledge, attitudes, and practices of Lebanese prenatal healthcare providers towards nutrition during pregnancy. Materials and Methods: A cross-sectional study using an online questionnaire was conducted. Health care providers were contacted by phone and email to participate in the online survey. A list of all clinics providing antenatal health services was obtained from the Order of Physicians and the Order of Midwives. A multistage random sample was selected. In the first stage, it was stratified per region (Beirut center or suburbs, and the southern region). In the second phase, it was stratified per clinic type (private, primary healthcare center, or hospital). Gynecologists and midwives who are members of the Order of Physicians and the Order of Midwives (n = 1333), were included. Results: Two-hundred and six responses (55% males) were obtained. Approximately 44% of the HCP were aged 50 and older, and 68.4% had more than 10 years of work experience. HCPs from Beirut represented 41.3% of the respondents. Eighty-eight percent of the HCPs were physicians, and 11% were midwives. The majority of the participants considered nutrition during pregnancy to be very important. Furthermore, half of these participants considered their position in delivering nutrition information as very significant. Most of the respondents reported that they provide nutrition advice to pregnant women, and they also received nutrition education during their profession. However, they perceived their nutrition knowledge as inadequate. Conclusion: Health care providers' attitude towards the importance of maternal nutrition and their confidence in talking about nutrition-related topics with pregnant women were positive despite the lack of knowledge in several areas related to nutrition during pregnancy. Therefore, there is a need for continuing nutrition education for health care providers and the implementation of nutrition education programs to achieve better health outcomes.

Actividad física en el embarazo y puerperio: prevalencia y recomendaciones de los profesionales sanitarios

OBJECTIVE

To assess changes in physical activity (PA) during pregnancy and after giving birth and to explore this according to age and educational level. To analyze whether the health professionals gave recommendations on PA.

DESIGN

Observational study. SITE: Information is derived from the Galician Risk Behavior Information System.

PARTICIPANTS

The target population was Galician women (aged 18-49 years) who delivered between september-2015 and august-2016.

MAIN MEASUREMENTS

The prevalence of walking, physical exercise and PA recommendations were estimated for three moments (pre-pregnancy, pregnancy and after delivery).

RESULTS

Walking during pregnancy increased by 34,0% and the performance of physical exercise decreased by 21,0%. After delivery, walking decreased by 37,0% and physical exercise decreased by 32,0% compared to pregnancy. Women of younger age and lower educational level were those who performed less PA. 72,6% and 22,1% of women declared that a healthcare professional recommended PA during pregnancy and after delivery, respectively.

CONCLUSION

The PA performed by women during pregnancy is mainly walking, and there is a concern about the abandonment of PA practice after delivery. Healthcare professionals recommend PA mainly during pregnancy, but little is recommended after delivery. It may be desirable for the improvement of this prevalence to reinforce health action.

A Qualitative Exploration of Exercise During Pregnancy

OBJECTIVE

To explore the experience of women engaging in physical activity during pregnancy.

DESIGN

This was the qualitative arm of the Starting Pregnancy With Robustness for Optimal Upward Trajectories (SPROUT) pilot project. Thematic analysis was used to realize patterns of meaning and significance from data on participants' experiences in engaging in physical activity during pregnancy.

SETTING

One-on-one structured interviews via video conferencing.

PARTICIPANTS

Eighteen women in the first trimester of their pregnancy were recruited from local obstetric practices and randomized into one of three exercise groups. All three groups of women were followed for their entire pregnancy and for 6 months postpartum.

METHODS

Interviews were recorded and analyzed using thematic analysis.

RESULTS

Six major themes important for clinical practice resulted from the analysis: Physical Activity During Pregnancy Is Desirous for Health Benefits, Activity Monitors Provide Motivation, Human Connection HelpsSupportPhysical Activity, More Guidance Is Needed on How to Be Physically Active During Pregnancy, A Supervised Physical Activity Program Is Preferred if Available and Flexible, and Participants Would Choose to Be Physically Active in Subsequent Pregnancies.

CONCLUSION

Human interaction, education on physical activity guidelines, and exercise advice increased motivation, accountability, and confidence in the women. Using a tracking device such as an activity watch provided real-world feedback in addition to fostering motivation.

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.

An mHealth Intervention to Reduce Gestational Obesity (mami-educ): Protocol for a Randomized Controlled Trial

BACKGROUND

The World Federation of Obesity warns that the main health problem of the next decade will be childhood obesity. It is known that factors such as gestational obesity produce profound effects on fetal programming and are strong predictors of overweight and obesity in children. Therefore, establishing healthy eating behaviors during pregnancy is the key to the primary prevention of the intergenerational transmission of obesity. Mobile health (mHealth) programs are potentially more effective than face-to-face interventions, especially during a public health emergency such as the COVID-19 outbreak.

OBJECTIVE

This study aims to evaluate the effectiveness of an mHealth intervention to reduce excessive weight gain in pregnant women who attend family health care centers.

METHODS

The design of the intervention corresponds to a classic randomized clinical trial. The participants are pregnant women in the first trimester of pregnancy who live in urban and semiurban areas. Before starting the intervention, a survey will be applied to identify the barriers and facilitators perceived by pregnant women to adopt healthy eating behaviors. The dietary intake will be estimated in the same way. The intervention will last for 12 weeks and consists of sending messages through a multimedia messaging service with food education, addressing the 3 domains of learning (cognitive, affective, and psychomotor). Descriptive statistics will be used to analyze the demographic, socioeconomic, and obstetric characteristics of the respondents. The analysis strategy follows the intention-to-treat principle. Logistic regression analysis will be used to compare the intervention with routine care on maternal pregnancy outcome and perinatal outcome.

RESULTS

The recruitment of study participants began in May 2022 and will end in May 2023. Results include the effectiveness of the intervention in reducing the incidence of excessive gestational weight gain. We also will examine the maternal-fetal outcome as well as the barriers and facilitators that influence the weight gain of pregnant women.

CONCLUSIONS

Data from this effectiveness trial will determine whether mami-educ successfully reduces rates of excessive weight gain during pregnancy. If successful, the findings of this study will generate knowledge to design and implement personalized prevention strategies for gestational obesity that can be included in routine primary care.

Determinants of weight gain and body changes during pregnancy: A qualitative study of French-Canadian pregnant people

OBJECTIVE

More than half of pregnant Canadian people exceed current gestational weight gain recommendations, which has been associated with adverse outcomes for both parent and child. Although the physiological causes of excessive gestational weight gain have been well investigated, few studies have evaluated the context of gestational weight gain and body changes through the perspective of pregnant people. Therefore, we aim to explore factors influencing body changes and weight gain during pregnancy as experienced by pregnant individuals.

METHODS

A total of three focus groups and six individual interviews were conducted with pregnant people (n=21) recruited in the 2^nd or 3^rd trimester. A semi-structured interview guide was developed according to a pre-existing conceptual model by Hill et al., 2013. Focus groups and interviews were recorded, transcribed, and thematically analysed using NVivo software.

FINDINGS

Results were categorized into four main themes, based on the conceptual model: (1) parental psychological, social and cognitive factors, (2) outcomes, (3) parental behaviors and (4) health behavior change constructs. Participants identified structural, social, professional, and especially partner support (1), health-related strategies (2), body image (1) and knowledge of gestational weight gain recommendations (3) as influent components of their body changes experience.

CONCLUSIONS

In this study, the themes addressed affect both pregnant individuals and their relatives. Enhanced knowledge of gestational weight gain recommendations in this population, support from relatives and quality of follow-up offered by health professionals must therefore be considered as possible avenues of intervention.

Empirical validation of the information-motivation-behavioral skills model of gestational weight management behavior: a framework for intervention

BACKGROUND

Unhealthy gestational weight gain is a modifiable risk factor for adverse maternal and child health. Appropriate and effective intervention strategies that focus on behavioral change or maintenance are critical in weight management during pregnancy. Our aim was to uncover the influencing factors and psychosocial mechanisms of gestational weight control behavior, and to construct a behavioral model suitable for intervention based on Information-Motivation-Behavioral skills (IMB) model.

METHODS

A sample of 559 pregnant women from a municipal maternal and child healthcare facility in Jiangsu Province, China was enrolled in this cross-sectional empirical study. Partial least square structural equation modelling was used to verify the hypothesized model, and post hoc analyses was used to test the effect of parity and pre-pregnancy BMI on the model.

RESULTS

The IMB model elements can predict gestational weight management (GWM) behavior well, with information being the most influential factor. As predicted, information affects GWM directly (β = 0.325, p < 0.05) and indirectly (β = 0.054, p < 0.05) through behavioral skills. Likewise, motivation has direct (β = 0.461, p < 0.05) effects on GWM, and has indirect (β = 0.071, p < 0.05) effects through behavioral skills. Behavioral skills have a direct impact (β = 0.154, p < 0.05). The model had a goodness of fit (GOF = 0.421) and was robust when tested in subgroups of different parity or pre-pregnancy BMI.

CONCLUSION

Findings from this study supported the predictions of the IMB model for GWM behavior, and identified its modifiable determinants. The tested behavior model for GWM can serve as a new validated intervention strategy in weight management among pregnant women.

Quality assessment of pre- and postnatal nutrition and exercise mobile applications in the United States and China

Background

Mobile applications (apps) are becoming increasingly prevalent as tools for improving maternal health behaviors. However, the recently updated content and quality of these apps remain unknown. This research investigated the fundamental characteristics, functional modules, and overall quality of maternal apps available in the United States and China to reveal critical nutrition and physical activity gaps.

Methods

A systematic search was performed in Android and iOS app stores (China and the United States). Apps were eligible if they targeted pregnant or postpartum women, focused on nutrition or physical activity, and had interfaces in English or Chinese. The basic characteristics, functional modules, and overall quality of the apps were evaluated, and differences between apps available in China or the United States were determined using analysis of variance and chi-square tests. Pearson correlations were utilized to investigate links between objective quality and user rating.

Results

A total of 65 maternity-related nutrition and physical activity apps (34 from China and 31 from the United States) were eligible. Among them, 68% (21/31) of US apps and 56% (19/34) of Chinese apps did not provide supporting evidence for their content. A greater number of Chinese apps provided app-based general education modules, namely food nutrition knowledge (n = 0, 0% in the United States vs. n = 30, 88.2% in China). Meanwhile, a greater number of US apps provided exercise modules, namely pregnancy yoga (n = 21, 67.7% in the United States vs. n = 2, 5.9% in China). The overall app quality rating in the United States was lower than it was in China (mean: 3.5, SD: 0.6 in China vs. mean: 3.4, SD: 0.7 in the United States). There was no relationship between the overall app quality rating and the user rating in either country (rho = 0.11 in China and rho = -0.13 in the United States).

Conclusion

The characteristics and functional modules of in-store apps for maternal nutrition and physical activity differed between the United States and China. Both countries' apps, especially Chinese apps, lacked evidence-based information, and there was no correlation between app quality and user rating. The results therefore suggest that user ratings cannot be used as an objective indicator of app quality and that it is necessary to improve the empirical basis and credibility of apps in both countries.

Using FIGO Nutrition Checklist counselling in pregnancy: A review to support healthcare professionals

The period before and during pregnancy is increasingly recognized as an important stage for addressing malnutrition. This can help to reduce the risk of noncommunicable diseases in mothers and passage of risk to their infants. The FIGO Nutrition Checklist is a tool designed to address these issues. The checklist contains questions on specific dietary requirements, body mass index, diet quality, and micronutrients. Through answering these questions, awareness is generated, potential risks are identified, and information is collected that can inform health-promoting conversations between women and their healthcare professionals. The tool can be used across a range of health settings, regions, and life stages. The aim of this review is to summarize nutritional recommendations related to the FIGO Nutrition Checklist to support healthcare providers using it in practice. Included is a selection of global dietary recommendations for each of the components of the checklist and practical insights from countries that have used it. Implementation of the FIGO Nutrition Checklist will help identify potential nutritional deficiencies in women so that they can be addressed by healthcare providers. This has potential longstanding benefits for mothers and their children, across generations.

Identifying barriers, facilitators, and interventions to support healthy eating in pregnant women with or at risk for hypertensive disorders of pregnancy

Background

Heart-healthy diets are important in the prevention and treatment of hypertension (HTN), including among pregnant women. Yet, the barriers, facilitators, and beliefs/preferences regarding healthy eating are not well described in this population.

Objective

To identify barriers and facilitators to healthy diet, examine the prevalence of food insecurity, and determine interest in specific healthy diet interventions.

Methods

Pregnant women, aged 18-50 years (N = 38), diagnosed with HTN, hypertensive disorders in pregnancy (HDP), or risk factors for HDP, were recruited from a large academic medical center in central Massachusetts between June 2020 and June 2022. Participants completed an electronic survey using a 5-point Likert scale (strongly disagree to strongly agree).

Results

The mean age of participants was 31.6 years (SD 5.5) and 35.1% identified as Hispanic. Finances and time were major barriers to a healthy diet, reported by 42.1% and 28.9% of participants, respectively. Participants reported that their partners and families were supportive of healthy eating and preparing meals at home, though 30.0% of those with children considered their children's diet a barrier to preparing healthy meals. Additionally, 40.5% of the sample were considered food insecure. Everyone agreed that healthy diet was important for maternal and fetal health, and the most popular interventions were healthy ingredient grocery deliveries (89.4%) and meal deliveries (84.2%).

Conclusion

Time and cost emerged as major challenges to healthy eating in these pregnant women. Such barriers, facilitators, and preferences can aid in intervention development and policy-level changes to mitigate obstacles to healthy eating in this vulnerable patient population.

Diet quality during pregnancy and its association with social factors: 3D Cohort Study (Design, Develop, Discover)

Good diet quality during pregnancy provides adequate nutrition to support both the mothers and the fetus. The objective of this study is to describe the distribution of diet quality during pregnancy and to study the association between social factors and diet quality during pregnancy in a Canadian population. This study was based on 1535 pregnant women who provided dietary information in the 3D Cohort Study in Quebec, Canada. A 3‐day food record was used to collect dietary intake in the second trimester of pregnancy. A Canadian adaption of the Healthy Eating Index (HEI‐C) 2010 was used to quantify diet quality. Univariate and multiple linear regression models were used to calculate unadjusted and adjusted effect estimates and confidence intervals for the association between social factors and HEI‐C. The mean HEI‐C 2010 score in this study was 62.9 (SD: 11.2). Only 4.5% and 8.3% of the pregnant women consumed the recommended amounts of whole grains and ‘greens and beans’, respectively. Diet quality was lower in some subgroups of pregnant women. After multivariable adjustment, lower diet quality was observed in participants who were less educated, younger, overweight or obese before pregnancy, or parous. There was an interaction between ethnicity and immigration status on diet quality in pregnancy. These findings could be useful for health practitioners and policymakers in developing strategies to improve the diet quality of pregnant women.

The diet of the women in Canada still needs improvement, especially regarding whole grains and ‘greens and beans’, where the majority of the women did not meet the recommendations.

Pregnant women who were less educated, younger, overweight or obese before pregnancy, or parous should be targeted for improving diet quality in Canada.

There was an interaction between ethnicity and immigration status on diet quality during pregnancy.

Systematic Review of Interventions Addressing Food Insecurity in Pregnant Women and New Mothers

PURPOSE OF THE REVIEW

Food insecurity can have a negative health impact for women during pregnancy and the postpartum period; however, there are a range of barriers to meeting nutritional guidelines during pregnancy. Food insecurity is associated with an increased risk of pregnancy complications and mental and physical health outcomes. This review aims to provide insight into programmes and interventions which have targeted food insecurity in pregnant and early postpartum women. The central research question for this review is as follows: What programmes and interventions have sought to address food insecurity among pregnant and postpartum women? A systematic search of five electronic databases including Medline, CINAHL, Global Health, Embase, and Cochrane was undertaken on August 2021. Key thematic areas searched were food insecurity, pregnancy, nutritional outcomes, and interventions or programmes. Only studies that were published since 2000 in English were considered.

RECENT FINDINGS

Eleven studies were included in this review. Studies employed a range of methods and outcomes measures. They were conducted in mostly low- and middle-income countries, and in general, focused on nutritional supplementation, with some studies also incorporating nutrition education or counselling. The findings of this review suggest that while there are a range of possible interventions that seek to address food insecurity and hunger among pregnant and postpartum women, the limited number of robust evaluations or long-term interventions mean that evidence for any one intervention type is limited. Furthermore, the programmes and interventions that do exist are generally embedded within a single context or structure, and as such, may not be able to be widely implemented.

Optimizing Maternal Nutrition: The Importance of a Tailored Approach

Improving nutritional status during pregnancy is a global interest. Frequently, women either fail to meet or exceed nutrient recommendations. Current strategies to improve maternal nutrition focus on a "one-size-fits-all" approach and fail to consider individual factors that affect the mother's overall nutritional status. The objectives of this review were to determine the importance of key nutrients for optimal maternal and fetal health, to explore to what extent current recommendations consider individual factors, and to explore novel strategies to close the gap between current guidelines and real-world challenges through more personalized approaches. This review intercalated different nutritional guidelines and recent scientific publications and research initiatives related to maternal nutrition. Based on that, an overview of current recommendations, challenges related to present approaches, and perspectives for future directions are described. Current guidelines are not optimally supporting adequate nutrient intake and health of expectant mothers and their offspring. Existing recommendations are not consistent and do not sufficiently take into account how interindividual variation leads to differences in nutrient status. Personalized nutrition offers women the opportunity to improve their health by using strategies that are tailored to their unique nutritional needs. Such strategies can include personalized supplementation, holistic lifestyle interventions, digital and application-based technologies, and dietary assessment through blood biomarker and genetic analysis. However, these approaches warrant further investigation and optimization. More personalized approaches have the potential to optimize mothers' and their offspring's health outcomes more appropriately to their nutritional needs before, during, and after pregnancy. Moving away from a generalized "one-size-fits-all" approach can be achieved through a variety of means. Future aims should be to provide supporting evidence to create customized subpopulation-based or individualized recommendations, improve nutrition education, and develop novel approaches to improve adherence to dietary and lifestyle interventions.

The lived experiences of women exploring a healthy lifestyle, gestational weight gain and physical activity throughout pregnancy

BACKGROUND

Weight gain is inevitable during pregnancy. However, high prepregnancy body mass index and excessive gestational weight gain are associated with poor pregnancy outcomes. Understanding the experiences, social influences and decisions women make to maintain a healthy lifestyle during pregnancy are essential to consider how to improve services and interventions to help women engage in a healthy diet and physical activity (PA) behaviours.

OBJECTIVE

The study investigated women's opinions and lived experiences of engaging in a healthy diet, promoting optimal gestational weight gain and PA during and after pregnancy.

DESIGN AND METHODS

Twenty-two pregnant women contributed to qualitative data collection for this Grounded Theory (GT) study. Nineteen women completed semi-structured interviews and three patient and public involvement (PPI) representatives sought to validate the analysis and GT framework.

RESULTS

Two substantive categories were constructed: (1) Evolving from 'I' to 'we', as informed by two subcategories and (2) the power of information and guidance, as informed by three subcategories. These categories informed the core category, 'A navigational journey and evolution of the pregnant self'. The navigational journey involves constantly searching for knowledge and information to support and balance the interests of personal beliefs, the health of their unborn baby, their social circle and the wider world. A woman's psychological capability (e.g., their knowledge of a healthy lifestyle and confidence to implement such knowledge) is continuously tested.

CONCLUSIONS

Pregnancy may create a 'teachable moment' but there is a need for appropriate guidance from professionals to assist with lifestyle choices during pregnancy. The findings showed a significant influence of online resources, and lack of guidance on behaviour during pregnancy and may highlight areas of focus for future research and intervention.

PUBLIC CONTRIBUTION

Three pregnant women were recruited to act as PPI representatives to assist with the validation of the analytical findings and aid the final theoretical saturation of the GT framework. Commentary from these PPI representatives was used to validate the analysis and support the interpretation of the data. In addition, these PPI representatives were also invited to provide commentary on the draft manuscript and those involved in this later process have been included as coauthors.

Physical activity during pregnancy: a systematic review for the assessment of current evidence with future recommendations

BACKGROUND

Physical activity is essential to maternal and infant health. Healthcare professionals should inform pregnant women about benefits of physical activity to prevent possible health issues. Those recommendations should elaborate on relevant contemporary evidence. The aim of this study was to review evidence-based recommendations for physical activity during pregnancy.

METHODS

A systematic search, analysis and synthesis of conducted randomised controlled trials (RCTs) was conducted from October 2021 to June 2022 in following databases: PubMed, CINAHL, ScienceDirect and Web of Science. Literature was searched using inclusion and exclusion criteria and following PRISMA recommendations.

RESULTS

Benefits for pregnant-women health and well-being were reported while performing aerobic exercise, lumbar stabilization and stretching exercise, water exercise, nerve and tendon-slip exercise, resistance training and strength training. For all exercise modalities it is recommended to perform moderate intensity activities during the whole time of pregnancy.

CONCLUSIONS

This systematic literature review supplements current knowledge on physical activity of pregnant women. Exercise interventions are listed and suggested in an integrative model with physical-fitness components to contextualize and promote physical activity among pregnant women.

Pregnant and Postpartum Women's Perceptions of Barriers to and Enablers of Physical Activity During Pregnancy: A Qualitative Systematic Review

INTRODUCTION

Physical activity throughout pregnancy has been shown to have health benefits for the pregnant person, including reductions in the risk of preeclampsia and gestational weight gain and improvements in blood pressure regulation. Despite the benefits, many pregnant women do not meet the guidelines for physical activity throughout pregnancy. Therefore, it is important to determine what influences women's activity levels during pregnancy. This systematic review of the qualitative literature aimed to determine pregnant and postpartum women's perceptions of barriers to and enablers of physical activity, specifically during pregnancy.

METHODS

MEDLINE, PsycINFO, CINAHL, and Embase were searched systematically to identify qualitative studies investigating pregnant or postpartum women's perceptions of barriers to and enablers of physical activity during pregnancy. Included studies were limited to populations of pregnant or postpartum women, the majority of whom were aged 18 to 40 years, and studies published from 1985 onward. Data quality was assessed using the Critical Appraisal Skills Programme Qualitative Studies Checklist. Data were extracted using NVivo software and subsequently mapped on the COM-B framework.

RESULTS

Twenty-five qualitative studies were included in this systematic review. Sixteen themes were identified that mapped onto 6 components of the COM-B framework. Commonly reported barriers to physical activity during pregnancy included pregnancy symptoms, lack of knowledge of what constitutes safe activity, and the opinions of women's social circles. Commonly reported enablers of physical activity during pregnancy were social support and the experienced benefits, including physiologic, psychological, and social benefits.

DISCUSSION

The results of this systematic review have clinical implications for perinatal care providers, as the overall benefits of physical activity during pregnancy have been well documented in previous studies. The authors recommend clinicians aim to explore pregnant women's perspectives on physical activity during pregnancy in order to be able to address their perceived barriers to and enablers of physical activity during pregnancy.

Preventive Counseling in Routine Prenatal Care-A Qualitative Study of Pregnant Women's Perspectives on a Lifestyle Intervention, Contrasted with the Experiences of Healthcare Providers

Maternal lifestyle during pregnancy and excessive gestational weight gain can influence maternal and infant short and long-term health. As part of the GeMuKi intervention, gynecologists and midwives provide lifestyle counseling to pregnant women during routine check-up visits. This study aims to understand the needs and experiences of participating pregnant women and to what extent their perspectives correspond to the experiences of healthcare providers. Semi-structured interviews were conducted with 12 pregnant women and 13 multi-professional healthcare providers, and were analyzed using qualitative content analysis. All interviewees rated routine check-up visits as a good setting in which to focus on lifestyle topics. Women in their first pregnancies had a great need to talk about lifestyle topics. None of the participants were aware of the link between gestational weight gain and maternal and infant health. The healthcare providers interviewed attributed varying relevance regarding the issue of weight gain and, accordingly, provided inconsistent counseling. The pregnant women expressed dissatisfaction regarding the multi-professional collaboration. The results demonstrate a need for strategies to improve multi-professional collaboration. In addition, health care providers should be trained to use sensitive techniques to inform pregnant women about the link between gestational weight gain and maternal and infant health.

Impact of Diet Quality during Pregnancy on Gestational Weight Gain and Selected Adipokines-Results of a German Cross-Sectional Study

While nutrition during pregnancy is critical for the health of both mother and child, little is known about the diet quality of women during pregnancy, its correlation with gestational weight gain (GWG)/body composition, and chosen maternal adipokines. Therefore, we evaluated the Healthy Eating Index (HEI) of 110 pregnant women and analyzed its correlation with GWG/body composition, physical activity, leptin, resistin, adiponectin, and interleukin 6 (IL-6), respectively. Diet quality was medium in 63% of women, characterized by a high intake of animal-based products. HEI was negatively influenced by pre-pregnancy obesity (β = −0.335, p = 0.004), and positively influenced by higher age (>35 yrs., β = 0.365, p ≤ 0.001), upper arm circumference (β = 0.222, p = 0.052), and total activity during the third trimester (β = 0.258, p = 0.008). GWG was associated with pre-pregnancy obesity (β = −0.512, p ≤ 0.001), thigh circumference (β = 0.342, p = 0.007), upper arm fat area (β = 0.208, p = 0.092), and maternal age group (>35 yrs. β = −0.166, p = 0.082), but not with HEI. Leptin and IL-6 displayed associations with variables representative of body composition, such as pre-pregnancy BMI, thigh circumference, upper arm fat area, and upper arm circumference, but were not influenced by HEI. Neither were adiponectin and resistin. IL-6 was also associated with total activity. In conclusion, GWG, leptin, and IL-6 were influenced by nutritional status (body composition/pre-pregnancy BMI), not by maternal diet. Physical activity level also had an impact on IL-6. Thus, efforts should be intensified to improve diet quality and participation in sports before and during pregnancy, particularly in overweight or obese women.

Uncovering Barriers to Prenatal Physical Activity and Exercise Among South African Pregnant Women: A Cross-Sectional, Mixed-Method Analysis

Background

The barriers to prenatal physical activity and exercise have been widely reported in the literature, highlighting context-specific challenges. However, generally, research on prenatal physical activity and exercise among pregnant women in South Africa is rare; and particularly concerning the barriers to their prenatal physical activity practice. This study assessed the barriers to physical activity participation among pregnant women in the Eastern Cape, South Africa.

Methods

This was a sequential explanatory mixed method, predominantly quantitative study involving 1,082 pregnant women. A structured self-administered questionnaire on perceived barriers to physical participation was applied to collect quantitative data; while a subset of 15 pregnant women participated in individual in-depth semi-structured interviews to augment quantitative data. Quantitative and qualitative data were analyzed using descriptive statistics and thematic analysis, respectively.

Results

The results of the quantitative analysis presented major barriers: lack of advice on prenatal physical activity and inadequate or conflicting information about prenatal physical activity; tiredness; work commitments; discomfort; lack of time; low energy; non-accessibility to physical activity; lack of financial resources, and safety concerns for the mother and the baby. Qualitatively, the barriers identified relate to four main themes: individual, lack of information, lack of resources, and environmental barriers.

Conclusion

The major barriers cited by the women were tiredness, lack of time, discomfort, and low energy. They also include lack of support, advice and information about prenatal physical activity. The multiple constraining factors responsible for low or non-prenatal physical activity of pregnant women in this setting highlight the need to tailor interventions to address their individual uniquely perceived barriers.

Evaluating Evidence-Based Content, Features of Exercise Instruction, and Expert Involvement in Physical Activity Apps for Pregnant Women: Systematic Search and Content Analysis

BACKGROUND

Guidelines for physical activity and exercise during pregnancy recommend that all women without contraindications engage in regular physical activity to improve both their own health and the health of their baby. Many women are uncertain how to safely engage in physical activity and exercise during this life stage and are increasingly using mobile apps to access health-related information. However, the extent to which apps that provide physical activity and exercise advice align with current evidence-based pregnancy recommendations is unclear.

OBJECTIVE

This study aims to conduct a systematic search and content analysis of apps that promote physical activity and exercise in pregnancy to examine the alignment of the content with current evidence-based recommendations; delivery, format, and features of physical activity and exercise instruction; and credentials of the app developers.

METHODS

Systematic searches were conducted in the Australian App Store and Google Play Store in October 2020. Apps were identified using combinations of search terms relevant to pregnancy and exercise or physical activity and screened for inclusion (with a primary focus on physical activity and exercise during pregnancy, free to download or did not require immediate paid subscription, and an average user rating of ≥4 out of 5). Apps were then independently reviewed using an author-designed extraction tool.

RESULTS

Overall, 27 apps were included in this review (Google Play Store: 16/27, 59%, and App Store: 11/27, 41%). Two-thirds of the apps provided some information relating to the frequency, intensity, time, and type principles of exercise; only 11% (3/27) provided this information in line with current evidence-based guidelines. Approximately one-third of the apps provided information about contraindications to exercise during pregnancy and referenced the supporting evidence. None of the apps actively engaged in screening for potential contraindications. Only 15% (4/27) of the apps collected information about the user's current exercise behaviors, 11% (3/27) allowed users to personalize features relating to their exercise preferences, and a little more than one-third provided information about developer credentials.

CONCLUSIONS

Few exercise apps designed for pregnancy aligned with current evidence-based physical activity guidelines. None of the apps screened users for contraindications to physical activity and exercise during pregnancy, and most lacked appropriate personalization features to account for an individual's characteristics. Few involved qualified experts during the development of the app. There is a need to improve the quality of apps that promote exercise in pregnancy to ensure that women are appropriately supported to engage in exercise and the potential risk of injury, complications, and adverse pregnancy outcomes for both mother and child is minimized. This could be done by providing expert guidance that aligns with current recommendations, introducing screening measures and features that enable personalization and tailoring to individual users, or by developing a recognized system for regulating apps.

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.

Barriers to weight management in pregnant mothers with obesity: a qualitative study on mothers with low socioeconomic background

BACKGROUND

Maternal obesity is a public health issue that could affect both women's and children's health. This qualitative study aimed to identify barriers to weight management of pregnant women with obesity and low socioeconomic backgrounds.

METHODS

The current qualitative study has been conducted using a grounded theory approach by analyzing data collected from in-depth interviews with clients of Tehran's public health care centers for prenatal care. The criteria for selecting participants were excessive weight gain during the first two trimesters of pregnancy, low socioeconomic status, and willingness to share their experiences. A semi-structured guide consisting of open-ended questions was asked in a private room. Open, axial, and selective coding were applied to the data.

FINDINGS

Four main themes emerged from data, each of which has some subcategories: 1) personal factors (unpleasant emotions and feelings, personal tastes/hobbies, workload and responsibilities, and history of diseases), 2) pregnancy status (unintended and high-risk pregnancy), 3) interpersonal relationships and support (lack of a spouse's support and unhealthy role modeling of relatives), 4) socio-cultural factors/influences (social norms and values, lack of access to health services, and unreliable information channels).

CONCLUSIONS

This study provides an overview of the barriers to the weight management of pregnant women from low socioeconomic backgrounds. The results could help develop appropriate health strategies for low socioeconomic women with obesity. Also, health care providers for this group of women could use these findings as a guide to consider their conditions and background.

Development and Validation of Prenatal Physical Activity Intervention Strategy for Women in Buffalo City Municipality, South Africa

Women rarely participate in physical activity during pregnancy, despite scientific evidence emphasising its importance. This study sought to develop an intervention strategy to promote prenatal physical activity in Buffalo City Municipality, Eastern Cape Province, South Africa. A multi-stage approach was utilised. The Strength, Weakness, Opportunity and Threat (SWOT) approach was applied to the interfaced empirical findings on prenatal physical activity in the setting. Subsequently, the Build, Overcome, Explore and Minimise model was then used to develop strategies based on the SWOT findings. A checklist was administered to key stakeholders to validate the developed strategies. Key strategies to promote prenatal physical activity include the application of the Mom-Connect (a technological device already in use in South Africa to promote maternal health-related information for pregnant women) in collaboration with cellphone and network companies; the South African government to integrate prenatal physical activity and exercise training in the medical and health curricula to empower the healthcare providers with relevant knowledge and skills to support pregnant women in prenatal physical activity counselling; provision of increased workforce and the infrastructure necessary in antenatal sessions and antenatal physical exercise classes and counselling; the government, in partnership with various stakeholders, to provide periodical prenatal physical activity campaigns based in local, community town halls and clinics to address the lack of awareness, misrepresentations and concerns regarding the safety and benefits of physical activity during pregnancy. The effective implementation of this developed prenatal physical activity by policymakers and health professionals may help in the promotion of physical activity practices in the context of women in the setting.
