Physical activity before and during pregnancy: A cohort study

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

BACKGROUND

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

AIM

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

METHODS

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

FINDINGS

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

CONCLUSION

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

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.

Influence of gestational weight gain on the nutritional status of offspring at birth and at 5 years of age

OBJECTIVE

To determine the influence of pre-pregnancy maternal BMI and increases in maternal weight during pregnancy on perinatal and child outcomes at birth and at 5 years.

RESEARCH DESIGN/SETTING

A prospective cohort study was conducted between November 2016 and December 2021. The participants were a total of 115 women-child dyads, selected from among pregnant women receiving routine prenatal care in different health centres belonging to 2 health districts. Follow-ups were conducted with the women during pregnancy and with their children during the 10 days after birth and at 5 years.

FINDINGS

The total weight gain during pregnancy is influenced by an inadequate pre-pregnancy BMI (0.03; 95 % CI, 0.004 - 0.25; P=.001) and a greater increase in maternal BMI during the first and second term of pregnancy. A greater increase in BMI during pregnancy was associated with higher breastfeeding rates both in the short term (1.21; 95 % CI, 1.01-1.44; P = 0.04) and the long term (12 months: 1.30; 95 % CI, 1.02 - 1.67; P = 0.04; 24 months: 1.30; 95 % CI, 1.02 - 1.69; P = 0.04). No links were found between gains in maternal weight and the weight of the newborn, nor between maternal weight and/or pre-pregnancy BMI with the nutritional status of the child.

KEY CONCLUSIONS

After studying these results, it was concluded that promoting and implementing health and education policies focused on enhancing maternal nutritional status is essential to improve the nutritional status of children.

IMPLICATIONS FOR PRACTICE

Healthy gestational weight gain (GWG) is an important issue to be addressed by the midwife in primary care, both in the preconception period and throughout pregnancy. As a result, it is important that the midwife is trained and has the appropriate resources and tools to work with pregnant women individually and collectively. In addition to paying attention to overweight and obese pregnant women, the midwife should also pay attention to women with a normal BMI, as they seem to have greater difficulty in maintaining a healthy weight gain. Another line of intervention to be addressed is breastfeeding (BF), where the midwife should be the main point of reference from the beginning of this process, taking into account the relationship between BMI and BF.

Physical activity during pregnancy and its relationship with gestational weight gain

Objective: to describe the physical activity patterns of a cohort comprised by pregnant women from our environment and to explore its association with weight gain in each of the trimesters of pregnancy. Methods: a descriptive and longitudinal study conducted with a sample of 151 women. The International Physical Activity Questionnaire was used to assess physical activity during pregnancy based on volume, intensity and setting where it is performed. Different multiple linear regression models were performed to analyze the association between physical activity and gestational weight gain Results: physical activity decreased during pregnancy, both in terms of time and intensity. Pre-gestational Body Mass Index was the main factor associated with lower weight gain throughout pregnancy. The influence of physical activity on gestational weight gain was limited to the third trimester of pregnancy, where an inverse association was observed between both variables. Conclusion: the results of this study show an important reduction in physical activity during pregnancy and suggest that it exerts a limited influence on gestational weight gain

Atividade física durante a gestação e sua relação com o ganho de peso gestacional

Objetivo: descrever os padrões de atividade física de uma coorte de gestantes em nosso meio e explorar sua associação com o ganho de peso em cada um dos trimestres de gestação. Método: estudo descritivo longitudinal com uma amostra de 151 mulheres. O Questionário Internacional de Atividade Física foi utilizado para avaliar a atividade física durante a gestação de acordo com o volume, intensidade e escopo do desempenho. Diferentes modelos de regressão linear múltipla foram utilizados para analisar a associação entre atividade física e ganho de peso gestacional. Resultados: a atividade física diminuiu durante a gestação, tanto em tempo quanto em intensidade. O índice de massa corporal pré-gestacional foi o principal fator associado ao menor ganho de peso ao longo da gestação. A influência da atividade física no ganho de peso gestacional limitou-se ao terceiro trimestre de gestação, no qual foi observada associação inversa entre ambas as variáveis. Conclusão: os resultados deste estudo mostram uma diminuição significativa da atividade física no momento da gravidez e sugerem uma influência limitada desta no ganho de peso gestacional.

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.

Longitudinal Analysis of Patterns and Correlates of Physical Activity and Sedentary Behavior in Women From Preconception to Postpartum: The Singapore Preconception Study of Long-Term Maternal and Child Outcomes Cohort

OBJECTIVE

Longitudinal changes in physical activity (PA) and sedentary behavior patterns from preconception to postpartum are not fully characterized. We examined changes and baseline sociodemographic/clinical correlates of PA and sedentary behavior in women from preconception to postpartum.

METHODS

The Singapore Preconception Study of Long-Term Maternal and Child Outcomes cohort recruited 1032 women planning pregnancy. Participants completed questionnaires at preconception, 34 to 36 weeks gestation, and 12 months postpartum. Repeated-measures linear regression models were used to analyze changes in walking, moderate to vigorous PA (MVPA), screen time, and total sedentary time, and to identify sociodemographic/clinical correlates associated with these changes.

RESULTS

Of the 373 women who delivered singleton live births, 281 provided questionnaires for all time points. Walking time increased from preconception to late pregnancy but decreased postpartum (adjusted means [95% CI]: 454 [333-575], 542 [433-651], and 434 [320-547] min/wk, respectively). Vigorous-intensity PA and MVPA decreased from preconception to late pregnancy but increased postpartum (vigorous-intensity PA: 44 [11-76], 1 [-3-5], and 11 [4-19] min/wk, MVPA: 273 [174-372], 165 [95-234], and 226 [126-325] min/wk, respectively). Screen time and total sedentary time remained consistent from preconception to pregnancy but decreased postpartum (screen: 238 [199-277], 244 [211-277], and 162 [136-189] min/d, total: 552 [506-598], 555 [514-596], and 454 [410-498] min/d, respectively). Individual characteristics of ethnicity, body mass index, employment, parity, and self-rated general health significantly influenced women's activity patterns.

CONCLUSION

During late pregnancy, walking time increased, while MVPA declined significantly, and partially returned to preconception levels postpartum. Sedentary time remained stable during pregnancy but decreased postpartum. The identified set of sociodemographic/clinical correlates underscores need for targeted strategies.

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.

ÜÇÜNCÜ TRİMESTERDA AYAKKABI UYGUNLUĞU, DÜŞME KORKUSU VE FİZİKSEL AKTİVİTE ARASINDAKİ İLİŞKİ

Purpose: Pregnancy is a time of intense physiologic and physical changes, especially in third trimester. The aim of this study was to investigate the relationship between the footwear suitability, fear of falling and physical activity in third trimester of pregnancy. Methods: One hundred twenty-three pregnant women aged between 18-40 years and a gestational age of 28 weeks and above were included the study. The Footwear Assessment Score was used to assess the suitability of the footwear. The fear of falling of the participants was measured using the Falls Efficacy Scale-International, and the physical activity level was measured using the International Physical Activity Questionnaire - short form. Results: A low negative correlation (r = -0.215; p < 0.05) was found between physical activity and fear of falling, and a low positive correlation (r = 0.256; p < 0.01) was found between footwear suitability and physical activity in pregnant women. There was no statistically significant relationship (r = -0.120; p = 0.185) between footwear suitability and fear of falling. Conclusion: According to the findings of the current study, it can be concluded that a more appropriate choice of shoes as the level of physical activity increases among pregnant women, and physical activity may reduce the fear of falling during pregnancy. Future studies are needed to investigate footwear suitability during pregnancy in more detail.

Caffeine Intake throughout Pregnancy, and Factors Associated with Non-Compliance with Recommendations: A Cohort Study

Maternal caffeine consumption is associated with adverse gestational outcomes. The aim of this study was to assess the intake of caffeine and factors associated with the non-adherence to caffeine intake recommendations in a cohort of 463 women before (T0) and in each trimester of gestation (T1, T2, and T3), by using validated questionnaires. Caffeine intake (median (mg/day), IQR) was 100.0 (181.1) at T0, 9.42 (66.2) at T1, 12.5 (65.6) at T2, and 14.0 (61.1) at T3 (p < 0.001). Non-compliance prevalence (intake > 200 mg/day) was 6.2% at T1, 4.2% at T2, and 2.7% at T3. Not being an active smoker at T1 (OR = 0.17; 95% CI 0.05−0.59) and T2 (OR = 0.22; 95% CI 0.09−0.52), adherence to the Mediterranean Diet at T1 (OR = 0.50; 95% CI 0.28−0.88) and T2 (OR = 0.39; 95% CI 0.15−1.02), and moderate physical activity at T1 (OR = 0.50; 95% CI 0.28−0.88) were inversely associated with caffeine consumption. Although caffeine intake may be considered low, intake prevalence increases throughout pregnancy. Although the main source of caffeine during pregnancy is coffee, attention must be also paid to the increasingly intake of chocolate, of which the effect during pregnancy is controversial. Smoking, non-adherence to a good quality diet, and light physical activity are associated with a higher caffeine intake and a lower compliance with caffeine intake recommendations. Perinatal dietary and lifestyle educational policies are needed.

Level of Physical Activity in Pregnant Populations from Different Geographic Regions: A Systematic Review

The aim of this study was to examine the level of physical activity during pregnancy in different populations worldwide. An intensive search was carried out from February until May 2021. The inclusion criteria were original studies of healthy pregnant women, and the main study variable was the assessment of physical activity. A total of 110 out of 1451 studies were assessed for inclusion, using the Newcastle–Ottawa Scale for quality, and for the risk of bias. The 44 analyzed articles were divided into 5 tables according to the characteristics of the intervention and the validated instrument used to measure physical activity (PA). A total of 59.09% of the studies indicated that participants had a low level of physical activity during pregnancy. In addition, the median quality score of the studies was 7.12, and 77.27% of the studies were cataloged as having a high-quality score. Although international guidelines recommend that women without a contraindication engage in prenatal physical activity, the results of the present study show that the level of PA is too low for women to achieve scientifically proven maternal-fetal benefits. Failure to achieve the recommended levels of weekly physical activity could pose significant risks to maternal well-being.

A self-efficacy-enhancing physical activity intervention in women with high-risk factors for gestational diabetes mellitus: study protocol for a randomized clinical trial

BACKGROUND

Gestational diabetes mellitus (GDM) is one of the most common medical disorders in pregnancy. Evidence has demonstrated that moderate-intensity physical activity may reduce the risk of gestational diabetes. However, women at risk of GDM spend most of their time performing sedentary behaviors. Although researchers identified self-efficacy as a mediator to overcome physical activity barriers, exercise intervention during pregnancy based on self-efficacy theory has not been discussed so far. Furthermore, there is conflicting evidence regarding the effects of a physical exercise intervention on the incidence of GDM and other maternal or neonatal outcomes in women at higher risk for GDM.

METHODS/DESIGN

A single-center, parallel, randomized controlled trial will be conducted in a maternal-child health care center. A total of 244 pregnant women at high risk for GDM will be randomized into a study group receiving a self-efficacy-enhancing physical activity intervention or a control group receiving the usual care. The intervention will consist of four group sessions and everyday reminders by WeChat (Tencent, Shenzhen, China). The program will begin at approximately 13-14+6 gestational weeks and end at 36+6 gestational weeks. The primary outcomes will include the incidence of GDM, blood sugar values, and physical activity. The secondary outcomes will include physical activity self-efficacy, gestational weight gain, maternal outcomes, and neonatal outcomes.

DISCUSSION

The findings of this research will contribute toward understanding the effects of a self-efficacy theory-oriented physical activity program on the incidence of GDM, blood sugar values, physical activity level, gestational weight gain, physical activity self-efficacy, maternal outcomes, and neonatal outcomes.

Longitudinal Nutritional Intakes in Italian Pregnant Women in Comparison with National Nutritional Guidelines

BACKGROUND

Nutritional quality during pregnancy is crucial for mother and child health and their short/long-term outcomes. The aim of this study is to evaluate the adherence to nutritional recommendations in Italy during the three pregnancy trimesters in Normal Weight (NW) and Over Weight (OW) women.

METHODS

Data from a multicenter randomized controlled trial included 176 women (NW = 133; OW = 43) with healthy singleton pregnancies enrolled within 13 + 6 weeks of gestation. Dietary intake was assessed every trimester by a Food Frequency Questionnaire.

RESULTS

OW and NW had similar gestational weight gain. However, as Institute of Medicine (IOM) recommend lower gestational weight gain (GWG) for OW, they exceeded the suggested range. In both groups, caloric intake during the three trimesters never met recommendations. Protein intake in first and second trimester was higher than recommendations, as was sugars percentage. Dietary fiber intake was lower in OW. Polyunsaturated fatty acids, calcium, iron and folic acid requirements were never satisfied, while sodium intake exceeded recommendations.

CONCLUSIONS

NW and OW women in Italy do not adhere to nutritional recommendations during pregnancy, with lower caloric intake, protein and sugars excess and inadequacies in micronutrients intake. Pregnant women in Italy should be provided with an adequate counseling and educational intervention as well as supplementation when indicated.

Clinical Practice Guidelines That Address Physical Activity and Exercise During Pregnancy: A Systematic Review

INTRODUCTION

Physical activity is recommended for healthy pregnant women. Clinical practice guidelines vary with regard to initial time, duration, or type of physical activity that is recommended, which is confusing for health care professionals and pregnant women alike. This study aimed to appraise clinical guidelines relevant to physical activity for pregnant women and summarize consensus and discrepant recommendations.

METHODS

The websites of organizations that develop guidelines including those of obstetricians, gynecologists, midwives, and medical sports associations were searched in addition to 9 literature databases for the period from January 2010 through November 2020. Guidelines were included if they were published in a journal or on a website in English or Chinese; were labeled as a recommendation guideline, position paper, practice parameter, or consensus statement; and addressed physical activity for pregnant women. Two authors independently extracted recommendations. Four reviewers independently assessed guideline quality using the AGREE II instrument.

RESULTS

Thirteen guidelines met the inclusion criteria. The guidelines developed by the World Health Organization and the National Institute for Health and Clinical Excellence were deemed to have the highest methodological quality. The recommendations were consistent with regard to recommended exercise duration, frequency, intensity, and type of physical activity. The main discrepant recommendations included best tools for conducting pre-exercise screening and assessing intensity of exertion. Guidelines also differ on optimal heart rate during exercise, when in pregnancy to initiate an exercise regimen, and duration or frequency of strengthening exercises.

DISCUSSION

Of the 13 guidelines, 2 were found to have good methodological quality. The recommendations that were consistent across the differing guidelines can support health care providers in counseling women about physical activity during pregnancy. The recommendations that are discrepant among these guidelines may contribute to confusion and a reluctance to recommend exercise during pregnancy. Research is needed to clarify discrepant recommendations.

Why do so many pregnant women give up exercise? An Italian cross-sectional study

Objective:

Current exercise guidelines recommend women to exercise throughout pregnancy, and the benefits are well documented. Still, there is an increasing decline of exercise levels during pregnancy and a high percentage of them are sedentary. It is well established that individual attitudes and perception of barriers may influence the ability to engage in sufficient amount of exercise. This has, however, not been examined in an Italian pregnant population. Hence, the aims of the present study were to increase knowledge of facilitators and barriers to regular exercise in Italian pregnant women and to report their social support in regard to maternal exercise.

Methods:

Healthy, pregnant women (n = 513) were allocated from Fatebenefratelli San Giovanni Calibita, a public hospital in Rome, and four antenatal clinics in Rome and Modena. The participants completed a validated self-administrated questionnaire, the Physical Activity Pregnancy Questionnaire, in gestational week 36. In line with current American College of Obstetricians and Gynecologists guidelines (2020), participants were categorized as “regular exercisers” (⩾150 min/week) and “not regular exercisers” (< 150 min/week).

Results:

Only 4.6% of the women engaged in regular physical activity/exercise in the third trimester. “Insufficient time” (54%) were the only barrier negatively associated with exercise. The facilitators “relaxation/recreation” (18%), “prevention of health complaints” (15%), “enjoyment” (10%), and “prevention of gestational weight gain” (4%) were associated with achieving the recommendations of exercise. This study found no association between achieving the recommendations and childhood exercise/having social modeling, or exercising network/milieu (p = 0.294 and p = 0.123). Nevertheless, exercising together with others was a significant predictor for regular maternal exercise (p < 0.001). Most women did not receive any advice on exercise during pregnancy from their doctor or midwife (60.0 %). Yet, those who received such advice were significantly more likely to exercise regularly compared to those who did not (75.0% vs 38.2%; p < 0.001).

Conclusion:

Italian pregnant women mainly reported internal facilitators for their willingness to participate in regular maternal exercise, while barriers were primarily related to inconveniences (such as insufficient time and difficulty combining with work/studies). The study addresses the positive association between achieving the recommended amount of exercise and social support in terms of exercising with others and getting advice from health professions. Because women respect their doctor and have regular prenatal checkups, this health care setting can play a pivotal role in the initiation and maintenance of exercise behavior during pregnancy.

Influence of the degree of adherence to the mediterranean diet and its components on cardiometabolic risk during pregnancy. The GESTAFIT project

BACKGROUND AND AIMS

Studies regarding dietary patterns and cardiometabolic risk markers during pregnancy are scarce. The aim of the present study was to analyse whether different degrees of adherence to the Mediterranean diet (MD) and the MD components were associated with cardiometabolic markers and a clustered cardiometabolic risk during pregnancy.

METHODS AND RESULTS

This study comprised 119 pregnant women from the GEStation and FITness (GESTAFIT) project. Dietary habits were assessed with a food frequency questionnaire at the 16th and 34th gestational weeks (g.w.). The Mediterranean Diet Score was employed to assess MD adherence. The following cardiometabolic markers were assessed: pre-pregnancy body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting glucose, triglycerides and high-density lipoprotein cholesterol (HDL-C). A greater MD adherence was associated with a better cardiometabolic status in cross-sectional (16th g.w. and 34th g.w.) and prospective analyses (MD adherence at the 16th g.w. and cardiometabolic markers at the 34th g.w.; SBP, DBP and HDL-C; all, p < 0.05). Participants with the highest MD adherence (Tertile 3) had a lower clustered cardiometabolic risk than those with the lowest MD adherence (Tertile 1) at the 16th and 34th g.w. (both, p < 0.05). A higher intake of fruits, vegetables and fish and a lower intake of refined cereals and red meat and subproducts were associated with a lower cardiometabolic risk during pregnancy (all, p < 0.05).

CONCLUSION

A higher MD adherence, a greater intake of fruits, vegetables and fish and a lower intake of refined cereals and red meat and subproducts showed a cardioprotective effect throughout gestation.
