Physical activity in pregnant women with Class III obesity: A qualitative exploration of attitudes and behaviours

Factors Influencing Weight Management in Pregnant Women with Overweight or Obesity: A Meta-Synthesis of Qualitative Studies

BACKGROUND

Overweight and obesity have multiple negative consequences for the health of both the mother and the child. Interventions to prevent excessive weight gain during pregnancy have had varying success, and the proportion of pregnant women who exceed national guidelines for weight gain continues to increase.

OBJECTIVE

To investigate the influence of factors on weight management among pregnant women with overweight or obesity.

METHODS

This meta-synthesis of qualitative studies involved searching databases PubMed, Embase, Cochrane, Scopus, and Web of Science. The databases were searched on October 4, 2022, and the search was updated on April 21, 2023. The screening of titles, abstracts, and full texts was conducted utilizing Covidence software. The quality assessment of the articles was performed using the Critical Appraisal Skills Programme checklist. The Enhancing Transparency in Reporting the Synthesis of Qualitative Research statement was used to enhance transparency in reporting. A meta-aggregation approach was used to guide the data extraction and synthesis.

RESULTS

A total of 46 studies with appropriate Critical Appraisal Skills Programme scores were included for qualitative synthesis. Findings were extracted and integrated into 4 themes: psychological factors (personally driven negative emotions and society-driven negative emotions), social factors (societal attitudes and beliefs and social support resources), factors related to education and counseling (information provision and communication), and factors associated with effective care (provided care components and the method of providing effective care).

CONCLUSIONS

To improve weight management during pregnancy, health care providers should provide tailored and individualized recommendations that take into consideration the factors influencing these women.

"Help me fight my constant battle": A focus group study of overweight and obese women's mHealth app experiences to manage gestational weight gain

OBJECTIVES

To understand and describe overweight and obese pregnant women's mHealth app experiences in managing gestational weight gain (GWG) for optimal weight goals.

DESIGN

A focus group study.

SETTING

We identified and invited pregnant women from a prenatal outpatient clinic in a metropolitan city in Northern Taiwan.

PARTICIPANTS

The participants were women whose pre-pregnancy BMI≥25 Kg/m² at antenatal booking, and have experience using smartphone apps for pregnancy e-information. A total of 13 overweight and obese women were agreed to participate, their gestation weeks from 11 to 38 weeks.

METHODS

Three focus group of six sessions were conducted from July to October of 2019. Thematic analysis was employed to inductively analyze the qualitative data.

FINDINGS

Overweight and obese pregnant women...s major concern was to safely deliver a healthy baby. Main themes identified included: planning to know more and wanting to do right, feeling like a failure and having low self-expectations, struggling with life and desiring peace of mind, yearning to be supported and hoping to be seen, adjusting for the future and embracing new technology to engage in GWG management.

KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

The core theme was presented as high BMI pregnant women...s shared need to be well-equipped to fight their constant weight battle, reflecting these women...s mixed feelings and barriers toward GWG control and body image during pregnancy. Experiences with a GWG addressing mHealth APP seemed to be positive and further facilitated healthy eating and physical activities, participants... self-efficacy may be increased along with satisfactory APP adherence to prevent excessive GWG for women with obesity.

Facilitators and barriers influencing weight management behaviours during pregnancy: a meta-synthesis of qualitative research

BACKGROUND

Obesity and overweight are considered risk factors for a range of adverse outcomes, including stillbirth. This study aims to identify factors reported by women influencing weight management behaviours during pregnancy.

METHODS

A systematic search was conducted in five databases from inception to 2019 and updated in 2021. Qualitative studies involving pregnant or post-partum women, from high-income countries, examining women's experiences of weight management during pregnancy were included. Meta-ethnography was used to facilitate the meta-synthesis of 17 studies.

RESULTS

Three themes were identified during the analysis: (1) Awareness and beliefs about weight gain and weight management, which included level of awareness and knowledge about dietary and exercise recommendations, risk perception and decision balance, perceived control over health and weight gain and personal insecurities. (2) Antenatal healthcare, women's experiences of their interactions with healthcare professionals during the antenatal period and the quality of the education received had an effect on women's behaviour. Further, our findings highlight the need for clear and direct information, and improved interactions with healthcare professionals, to better support women's weight management behaviours. (3) Social and environmental influence, the social judgement and stigmatization associated with overweight and obesity also acted as a negative influence in womens' engagement in weight management behaviours.

CONCLUSION

Interventions developed to promote and maintain weight management behaviours during pregnancy should consider all levels of influence over women's behaviours, including women's level of awareness and beliefs, experiences in antenatal care, education provision and social influence.

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.

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.

Fear-related barriers to physical activity among adults with overweight and obesity: A narrative synthesis scoping review

Physical activity is a health behavior contributing to successful weight management. Adults with overweight and obesity find it challenging to meet recommended activity guidelines because of a range of barriers, some of which are not yet fully understood. A barrier receiving limited consideration, compared with other literature within this field, is that of fear. The purpose of this scoping review was to establish the extent of literature on fear-related barriers to physical activity in adults with overweight or obesity and to identify gaps in this literature. The review followed the scoping review framework outlined by Arksey and O'Malley and adhered to the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews guidelines. The findings of the identified papers were charted thematically using a framework of fears and age group. In total, 34 studies were included that identified nine different fears related to barriers to activity in this population. However, only a small number of studies (n = 5) had explicitly intended to explore fear-related barriers. There were notable knowledge gaps including activity-related fear of pain and movement in adults under 45 years of age. There is a strong rationale to further explore these fears because they may restrict health promoting behavior.

Physical activity motives, barriers, and preferences in people with obesity: A systematic review

Background

Although the benefits of physical activity (PA) are well known, physical inactivity is highly prevalent among people with obesity. The objective of this systematic review was to i) appraise knowledge on PA motives, barriers, and preferences in individuals with obesity, and ii) quantify the most frequently reported PA motives, barriers and preferences in this population.

Methods

Six databases (Pubmed, CINAHL, Psyarticle, SportDiscus, Web of science and Proquest) were searched by independent reviewers to identify relevant quantitative or qualitative articles reporting PA motives, barriers or preferences in adults with body mass index ≥ 30 kg/m² (last searched in June 2020). Risk of bias for each study was assessed by two independent reviewers with the Mixed Methods Appraisal Tool (MMAT).

Results

From 5,899 papers identified, a total of 27 studies, 14 quantitative, 10 qualitative and 3 mixed studies were included. About 30% of studies have a MMAT score below 50% (k = 8). The three most reported PA motives in people with obesity were weight management, energy/physical fitness, and social support. The three most common PA barriers were lack of self-discipline/motivation, pain or physical discomfort, and lack of time. Based on the only 4 studies available, walking seems to be the preferred mode of PA in people with obesity.

Conclusions

Weight management, lack of motivation and pain are key PA motives and barriers in people with obesity, and should be addressed in future interventions to facilitate PA initiation and maintenance. Further research is needed to investigate the PA preferences of people with obesity.

Impact of physical activity on course and outcome of pregnancy from pre- to postnatal

A healthy lifestyle that includes physical activity has numerous positive effects on the mother and child during and after pregnancy. In this context physical activity plays a central role due to its influence on body composition. While visceral fatty tissue has a pro-inflammatory effect via so-called adipokines, myokines seem to have a more anti-inflammatory effect and thus prevent numerous diseases such as gestational hypertension or gestational diabetes. However, many women show a decreased level of physical activity during pregnancy when compared to pre-gestation levels. The reasons underlying this change are manifold and include concern about the effects of physical exertion on the unborn child. Gynaecologists and midwives are also often uncertain about what specific advice to give regarding physical activity. The present review describes, besides the underlying mechanisms, current physical activity recommendations and corresponding evidence with a focus on weight development in terms of obesity, gestational diabetes and foetal outcome.

Physical activity and exercise during pregnancy in Africa: a review of the literature

BACKGROUND

Pregnancy is an important phase in a woman's life, with health status at this stage affecting both the woman and her child's life. Global evidence suggests that many women engage in low levels of physical activity (PA) and exercise during pregnancy despite its beneficial effects. This is particularly the case in Africa.

METHODS

This article reviews the literature on levels of PA and exercise among pregnant women in Africa, highlighting the level of PA or exercise participation during pregnancy in Africa, including types of PA, factors affecting PA, beliefs about and benefits of prenatal activity, advice or counselling on PA during pregnancy in Africa, and PA interventions proposed to promote the uptake of prenatal PA. Electronic search databases used were Google Scholar, Science Direct, Scopus, EMBASE, ERIC, Medline, Web of Science, EBSCOhost, PubMed, BIOMED Central, and African Journal Online. The basic search terms were: 'Physical activity', 'Exercise', 'Pregnancy', 'Pregnant women' and 'Africa'. A total of 40 references were found. On the basis of an analysis of titles, abstracts and the language of publication (other than English), 11 articles were rejected, and 29 articles were fully read, although two had to be rejected due to a lack of access to the full version. Finally, 27 references were included in the review.

RESULTS

Few studies exist on PA during pregnancy in Africa. The limited data available suggests that, compared to the Western world, pregnant women in Africa do not adhere to the recommendations for PA during pregnancy. Levels of participation in PA during pregnancy are low and decline as the pregnancy progresses. The majority of the studies used direct, objective measures to assess PA during pregnancy. Personal and environmental factors such as lack of time, lack of knowledge, inadequate information from healthcare providers, feelings of tiredness and an absence of social support constituted the main barriers to PA during pregnancy. The types of PA participation among pregnant women varied across studies and geographical settings.

CONCLUSIONS

While published data is limited, it seems clear that the participation of pregnant women in PA during pregnancy in Africa is low and declines with advancing pregnancy. There is a need for more studies to examine the dynamics of PA during pregnancy in Africa to guide contextual interventions to improve and promote maternal health on the continent.

Being with others during physical activity: experiences of well-being among adults with severe obesity

BACKGROUND

The experience of physical activity is influenced by social relations and gendered roles. Group-based lifestyle interventions are considered effective in promoting physical activity, yet the experiences of being active with others are unknown among individuals with severe obesity.

PURPOSE

To explore how individuals with severe obesity experience being with others during physical activity.

METHODS

A qualitative hermeneutic phenomenological study of repeated single-gender focus group interviews was conducted with adults living with severe obesity during group-based lifestyle intervention.

RESULTS

Three themes were developed: 1) 'Enjoying safety, kinship and belonging among peers'; 2) 'Feeling like a failure is shameful: A sense of aversion'; and 3) 'Striving to feel at home in physical activity: Needing distance from others.' The themes were drawn into an overall meaning 'Achieving wellbeing may always be a challenge: not feeling at home in the group or in body.'

CONCLUSION

Intersubjective and spatial dimensions of experiences are central and influence how individuals with severe obesity can feel wellbeing and 'at home' in physical activity. Physiotherapists should be aware of the individuals' vulnerability regarding feelings of failure, aversion, and shame as well as awareness of gendered norms and roles.

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

OBJECTIVE

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

INTENDED USERS

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

TARGET POPULATION

Women with obesity who are pregnant or planning pregnancies.

EVIDENCE

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

VALIDATION METHODS

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

BENEFITS, HARMS, AND COSTS

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

GUIDELINE UPDATE

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

SPONSORS

This guideline was developed with resources funded by the SOGC.

"Sit Yourself Down": Women's Experiences of Negotiating Physical Activity During Pregnancy

Approaches to understanding why physical activity (PA) tends to decline during pregnancy are generally based on individualized behavioral models, examining "barriers" or "enablers." In contrast, we used a social practice approach to explore the ways in which women negotiate PA during pregnancy within the contexts and routines of their everyday lives. Semistructured interviews were conducted with 18 pregnant women who had been classed as being at risk of gestational diabetes. We found that leisure-time physical activities were valued as pleasurable and therapeutic, but women's roles as employees and carers for others often constrained their opportunities for leisure-time PA. Women encountered others' expectations that they should sit down and slow down. This surveillance was often resisted, as women relied on "listening to the body" as a way to negotiate PA. These findings have important implications for public health strategies or interventions designed to promote PA during pregnancy.

Obesity in Pregnancy - Patient-Reported Outcomes in Qualitative Research: A Systematic Review

The purpose of this study was to determine the clinical and non-clinical outcomes that pregnant women with obesity value as pertaining to their health and that of their babies. In this systematic review of the qualitative literature, a search of four databases was conducted for studies using qualitative methods in pregnant women with obesity. From the included studies, the review synthesized relevant themes representing the voiced concerns and perceived benefits of and barriers to the uptake of interventions, to yield patient-reported outcomes (PROs). PROs were categorized into domains according to the published taxonomy of outcomes in medical research. Of the 89 identified studies, 27 were included, none of which were primarily intended to elicit PROs. A total of 256 PROs and 7 distinct themes were identified. Only 13% of PROs represented physiological or clinical outcomes, whereas 21% represented the core area of emotional functioning or well-being, and 15% represented the area of delivery of care. The most frequently voiced concern was inadequate health care provider support (60%), and women considered intervention-specific challenges to be the greatest barriers to the uptake of interventions (34%). This study synthesized the qualitative evidence of concerns that pregnant women with obesity have regarding their pregnancy and postpartum care, as well as specific barriers they perceive to the uptake of interventions. In addition, this study revealed that clinical outcomes, which are most often reported in clinical trials, comprise only a minority of outcomes considered important by these women. A core outcome set that adequately incorporates PROs is required to inform the conduct of future trials in pregnant women with obesity.

Perceptions of risk and influences of choice in pregnant women with obesity. An evidence synthesis of qualitative research

Background

Between 7–35% of the maternity population are obese in high income countries and 1–40% in lower or middle-income countries. Women with obesity are traditionally limited by the choices available to them during pregnancy and birth because of the higher risk of complications. This evidence synthesis set out to summarise how women with obesity’s perceptions of pregnancy and birth risk influence the care choices that they make.

Methods

A search of medical and health databases for qualitative studies written in the English language, published Jan 1993—April 2019 and reporting on pregnant women with obesity’s perception of risk and influence of pregnancy and birth choices. Data was extracted by two reviewers onto a questions framework and then analysed using a thematic synthesis technique. Confidence in the qualitative findings was assessed using GRADE-CERQual.

Results

23 full texts were included. The common themes on perception of risk were: ‘Self-blame arising from others’ stereotyped beliefs ‘, ‘Normalisation’, ‘Lack of preparation’, ‘Fearful acceptance and inevitability’ and ‘Baby prioritised over mother’. For influence of choices, the themes were: ‘External influences from personal stresses’, ‘Restrictive guidelines’, ‘Relationship with healthcare professional’ and ‘Perception of Risk’.

Conclusions

Evidence on what influences women with obesity’s pregnancy choices is limited. Further research is needed on the best methods to discuss the risks of pregnancy and birth for women with obesity in a sensitive and acceptable manner and to identify the key influences when women with obesity make choices antenatally and for birth planning.

An antenatal wish list: A qualitative systematic review and thematic synthesis of UK dietary advice for weight management and food borne illness

OBJECTIVES

To understand UK women's experiences of antenatal dietary advice for risk of food borne illness and weight gain.

DESIGN

A systematic review and thematic synthesis of peer-reviewed qualitative studies. PubMed, MEDLINE, CINAHL and PMC databases were searched for articles published from January 2008 to June 2018. The search strategy combined terms for pregnancy with terms for body composition, weight change, food safety, nutrition, diet and qualitative terminology. Studies were eligible for inclusion if (1) they explored experiences of implementing advice received during pregnancy for nutrition, physical activity and/or weight gain, and (2) participants were women who had experienced maternity care in the UK. Study quality was appraised using the Critical Appraisal Skills Programme (CASP) qualitative research appraisal tool.

FINDINGS

Of 25,688 articles identified by the search strategy, 20 studies were identified that met the inclusion criteria. Five major themes were recognised: control, barriers to diet and exercise, motivators, relationship with weight, and information, with a further 12 subthemes. The majority of studies reported on weight gain (n = 10).

KEY CONCLUSIONS

Evidence shows that UK antenatal dietary advice is currently inconsistent, vague and overwhelming despite pregnancy being an excellent time for lifestyle change. Women are primarily driven by the health of their baby and desire support to facilitate positive changes.

IMPLICATIONS FOR PRACTICE

Findings outline a wishlist which highlights a desire for tailored information on preventing weight gain, dietary requirements, safe physical activity and a deprioritisation of food safety guidelines. This provision should be delivered by HCP. e.g. midwives, in a sensitive and supportive way to bridge the gap between women's needs and the current antenatal provision.

Activity behaviors in lean and morbidly obese pregnant women

Interventions to increase physical activity in pregnancy are challenging for morbidly obese women. Targeting sedentary behaviors may be a suitable alternative to increase energy expenditure. We aimed to determine total energy expenditure, and energy expended in sedentary activities in morbidly obese and lean pregnant women. We administered the Pregnancy Physical Activity Questionnaire (nonobjective) and the Actical accelerometer (objective) to morbidly obese (BMI ≥ 40 kg/m²) and lean (BMI ≤ 25 Kg/m²) pregnant women recruited in early (<24 weeks), and late (≥24 weeks) gestation. Data are mean (SD). Morbidly obese pregnant women reported expending significantly more energy per day in early (n = 140 vs 109; 3198.4 (1847.1) vs 1972.3 (10284.8) Kcal/d, P < .0001) and late (n = 104 vs 64; 3078.2 (1356.5) vs 1947.5 (652.0) Kcal/d, P < .0001) pregnancy, and expended significantly more energy in sedentary activities, in early (816.1 (423.5) vs 540.1 (244.9) Kcal/d, P < .0001) and late (881.6 (455.4) vs 581.1 (248.5) Kcal/d, P < .0001) pregnancy, than lean pregnant women. No differences were observed in the proportion of energy expended sedentary between lean and morbidly obese pregnant women. The greater total energy expenditure in morbidly obese pregnant women was corroborated by Actical accelerometer in early (n = 14 per group, obese 1167.7 (313.6) Kcal; lean 781.1 (210.1) Kcal, P < .05), and in late (n = 14 per group, obese 1223.6 (351.5) Kcal; lean 893.7 (175.9) Kcal, P < .05) pregnancy. In conclusion, non-objective and objective measures showed morbidly obese pregnant women expended more energy per day than lean pregnant. Further studies are needed to determine whether sedentary behaviors are a suitable target for intervention in morbidly obese pregnancy.

Attitudes, barriers and enablers to physical activity in pregnant women: a systematic review

QUESTION

What are the attitudes, barriers and enablers to physical activity perceived by pregnant women?

DESIGN

In a systematic literature review, eight electronic databases were searched: AMED, CINAHL, Embase, Joanna Briggs Institute, Medline, PsycInfo, SPORTDiscus (from database inception until June 2016) and PubMed (from 2011 until June 2016). Quantitative data expressed as proportions were meta-analysed. Data collected using Likert scales were synthesised descriptively. Qualitative data were analysed thematically using an inductive approach and content analysis. Findings were categorised as intrapersonal, interpersonal or environmental, based on a social-ecological framework.

PARTICIPANTS

Pregnant women.

INTERVENTION

Not applicable.

OUTCOME MEASURES

Attitudes and perceived barriers and enablers to physical activity during pregnancy.

RESULTS

Forty-nine articles reporting data from 47 studies (7655 participants) were included. Data were collected using questionnaires, interviews and focus groups. Meta-analyses of proportions showed that pregnant women had positive attitudes towards physical activity, identifying it as important (0.80, 95% CI 0.52 to 0.98), beneficial (0.71, 95% CI 0.58 to 0.83) and safe (0.86, 95% CI 0.79 to 0.92). This was supported by themes emerging in 15 qualitative studies that reported on attitudes (important, 12 studies; beneficial, 10 studies). Barriers to physical activity were predominantly intrapersonal such as fatigue, lack of time and pregnancy discomforts. Frequent enablers included maternal and foetal health benefits (intrapersonal), social support (interpersonal) and pregnancy-specific programs. Few environmental factors were identified. Little information was available about attitudes, barriers and enablers of physical activity for pregnant women with gestational diabetes mellitus who are at risk from inactivity.

CONCLUSION

Intrapersonal themes were the most frequently reported barriers and enablers to physical activity during pregnancy. Social support also played an enabling role. Person-centred strategies using behaviour change techniques should be used to address intrapersonal and social factors to translate pregnant women's positive attitudes into increased physical activity participation.

Incorporating the 'Theory of Planned Behavior' into personalized healthcare behavior change research: a call to action

The 'Theory of Planned Behavior' (TPB) has been tested and validated in the scientific literature across multiple disciplines and is arguably the most widely accepted theory among behavior change academics. Despite this widespread acceptability, the TPB has yet to be incorporated into personalized healthcare behavior change research. Several prominent personalized healthcare researchers suggest that personalizing healthcare recommendations have a positive impact on changes in lifestyle habits. However, research in this area has demonstrated conflicting findings. We provide a scientific and theoretical basis to support a proposed expansion of the TPB to include personalization, and call to action-personalized healthcare behavior change researchers to test this expansion. Specific recommendations for study design are included.

Running Exercise in Obese Pregnancies Prevents IL-6 Trans-signaling in Male Offspring

PURPOSE

Maternal obesity is known to predispose the offspring to impaired glucose metabolism and obesity associated with low-grade inflammation and hypothalamic dysfunction. Because preventive approaches in this context are missing to date, we aimed to identify molecular mechanisms in the offspring that are affected by maternal exercise during pregnancy.

METHODS

Diet-induced obese mouse dams were divided into a sedentary obese (high-fat diet [HFD]) group and an obese intervention (HFD-running intervention [RUN]) group, which performed voluntary wheel running throughout gestation. Male offspring were compared with the offspring of a sedentary lean control group at postnatal day 21.

RESULTS

HFD and HFD-RUN offspring showed increased body weight and white adipose tissue mass. Glucose tolerance testing showed mild impairment only in HFD offspring. Serum interleukin-6 (IL-6) levels, hypothalamic and white adipose tissue IL-6 gene expressions, and phosphorylation of signal transducer and activator of transcription 3 in HFD offspring were significantly increased, whereas HFD-RUN was protected against these changes. The altered hypothalamic global gene expression in HFD offspring showed partial normalization in HFD-RUN offspring, especially with respect to IL-6 action.

CONCLUSION

Maternal exercise in obese pregnancies effectively reduces IL-6 trans-signaling and might be the underlying mechanism for the amelioration of glucose metabolism at postnatal day 21 independent of body composition.

What helps or hinders midwives to implement physical activity guidelines for obese pregnant women? A questionnaire survey using the Theoretical Domains Framework

OBJECTIVE

to investigate barriers and facilitators to physical activity (PA) guideline implementation for midwives when advising obese pregnant women.

DESIGN

a cross-sectional, self-completion, anonymous questionnaire was designed using the Theoretical Domains Framework. this framework was developed to evaluate the implementation of guidelines by health care professionals. A total of 40 questions were included. These were informed by previous research on pregnant women's and midwives views, knowledge and attitudes to PA, and supported by national evidence based guidelines. Demographic information and free text comments were also collected.

SETTING

three diverse NHS Trusts in the North East of England.

PARTICIPANTS

all midwives employed by two hospital Trusts and the community midwives from the third Trust (n=375) were invited to participate.

MEASUREMENTS

mean domain scores were calculated. Factor and regression analysis were performed to describe which theoretical domains may be influencing practice. Free text comments were analysed thematically.

FINDINGS

192 (53%) questionnaires were returned. Mean domain scores were highest for social professional role and knowledge, and lowest for skills, beliefs about capabilities and behaviour regulation. Regression analysis indicated that skills and memory/attention/decision domains had a statistically significant influence on midwives discussing PA with obese pregnant women and advising them accordingly. Midwives comments indicated that they felt it was part of their role to discuss PA with all pregnant women but felt they lacked the skills and resources to do so effectively.

KEY CONCLUSIONS

midwives seem to have the necessary knowledge about the need/importance of PA advice for obese women and believe it is part of their role, but perceive they lack necessary skills and resources, and do not plan or prioritise the discussion regarding PA with obese pregnant woman.

IMPLICATIONS FOR PRACTICE

designing interventions that improve skills, promote routine enquiry regarding PA and provide resources (eg. information, referral pathways) may help improve midwives' PA advice.

Perceived barriers to leisure-time physical activity during pregnancy: A literature review of quantitative and qualitative evidence

OBJECTIVES

Identify perceived barriers to leisure-time physical activity during pregnancy to inform future interventions aimed at improving physical activity levels in pregnancy.

DESIGN

PubMed/Medline and Web of Science databases were systematically searched using a reference period between 1986 and January/2016.

METHODS

A comprehensive search strategy was developed combining the following keywords: (barriers OR constraints OR perceptions OR attitudes) AND (physical activity OR exercise OR motor activity) AND (pregnancy OR pregnant women OR antenatal OR prenatal). Thematic synthesis was conducted to analyze the data. A socioecological model was used to categorize the reported barriers.

RESULTS

Twelve quantitative studies and 14 qualitative studies were included. Barriers belonging to the intrapersonal level of the socioecological model were the most reported in the studies and were categorized in five themes as follows: (1) Pregnancy-related symptoms and limitations; (2) Time constraints; (3) Perceptions of already being active, (4) Lack of motivation and (5) Mother-child safety concerns. At the interpersonal level, barriers were coded into two descriptive themes: (1) Lack of advice and information and (2) Lack of social support. Two other themes were used to summarize Environmental, Organizational and Policy barriers: (1) Adverse weather and (2) Lack of resources.

CONCLUSIONS

A range of relevant barriers to leisure-time physical-activity engagement during pregnancy were identified in this literature review. Pregnancy-related symptoms and limitations barriers were the most reported in studies, regardless of study design. Mother-child safety concerns, lack of advice/information and lack of social support were also important emphasized pregnancy-related barriers to be targeted in future interventions.
