Factors influencing physical inactivity status among chinese pregnant women: a cross-sectional study

Health-promoting lifestyles and influencing factors among pregnant women with urinary incontinence: a multicentre cross-sectional study

OBJECTIVE

Lifestyle modification is an important part of non-surgical treatment for urinary incontinence (UI) and is strongly recommended. This study aims to explore the status and influencing factors of health-promoting lifestyle among pregnant women with UI.

DESIGN

A multicentre cross-sectional study.

SETTING

This study was conducted in obstetric clinics of three tertiary-level A hospitals in Zhejiang Province, mainland China.

PARTICIPANTS

A total of 519 pregnant women with UI were enrolled in this study from May 2023 to August 2023.

OUTCOME MEASURES

Lifestyle Profile Scale for Gravidas with Urinary Incontinence (LPG-UI) was used to assess health-promoting lifestyle status. Multivariate stepwise linear regression analysis was performed to identify significant influence factors.

RESULTS

Most participants reported mild-to-moderate UI, with over 60% experiencing UI starting from the first and second trimesters. The mean score of LPG-UI was 86.74 (SD=12.75) out of a score of 120. The results of multivariate stepwise linear regression analysis showed that those who had better environmental satisfaction (β=0.22, p<0.001), self-efficacy (β=0.168, p<0.001), social support (β=0.153, p<0.001) and knowledge of UI (β=0.104, p<0.01) have higher levels of health-promoting lifestyles, while those who had worse depression (β=-0.214, p<0.001), fewer exercise before pregnancy (β=-0.135, p<0.001) and physical work (β=-0.076, p<0.05) have lower levels of health-promoting lifestyles. A total of 38.5% variation in the regression equation could be explained.

CONCLUSIONS

The health-promoting lifestyle of pregnant women with UI needs to be further promoted. Governments and the social sector need to do more to improve the accessibility of environments such as sports and healthcare. Meanwhile, increasing the individual health responsibility of pregnant women with UI and promoting help-seeking behaviours are also top priorities. More social and emotional support should be added to improve self-efficacy and positive moods to enhance health promotion lifestyles.

Assessment of Knowledge and Attitude of Antenatal Mothers Regarding Physical Activity During Pregnancy: A Cross-Sectional Analytical Study at a Tertiary Care Hospital in Puducherry, India

INTRODUCTION

A woman's body experiences numerous physiological and psychological changes throughout pregnancy in order to accommodate the expanding requirements of the growing fetus. These changes can lead to various pregnancy-related health issues like gestational diabetes, and pre-eclampsia. Women who regularly engage in physical activity during pregnancy have a reduced risk of developing those health problems. Pregnant women should have adequate knowledge and a good attitude towards physical activity during pregnancy, which is an essential precursor for practising exercise. Therefore, this study aimed to assess the knowledge and attitude of antenatal mothers regarding physical activity during pregnancy at a tertiary care hospital in Puducherry.

METHOD

A cross-sectional analytical study design was performed to collect data from 380 antenatal mothers. A convenient sampling technique was used to select the study participants. A structured, validated, self-administered questionnaire was used to collect data from pregnant women attending the antenatal outpatient department of Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER). Data were coded and analysed by IBM SPSS Statistics for Windows, Version 19.0 (Released 2010; IBM Corp., Armonk, New York, United States).

RESULTS

This study revealed that almost half of the antenatal mothers (n=195, 51.3%) had adequate knowledge whereas 185 (48.7%) had inadequate knowledge regarding physical activity during pregnancy. Regarding their attitude, most of the antenatal mothers (n=303, 79.7%) had a favourable attitude and 77 (20.3%) had an unfavourable attitude towards physical activity during pregnancy. It was found that there is a significant association between education, employment, pre-pregnancy physical activity status, co-morbidities, and BMI of the antenatal mothers and their level of knowledge (p < 0.05). Also, educational status, employment status, level of activity in day-to-day life, pre-pregnancy physical activity status, co-morbidities, and number of antenatal visits attended by the antenatal mothers were significantly associated with their level of attitude (p < 0.05).

CONCLUSION

The level of knowledge regarding physical activity during pregnancy was adequate among antenatal mothers and their attitude seems to be favorable. This does not mean that they are exercising effectively. Therefore, health professionals should put forth their effort to bring about behavioural change among pregnant women towards exercise by conducting counselling sessions, and antenatal exercise classes during their antenatal care visits in order to empower pregnant women to lead a healthy pregnancy.

Physical activity levels and influencing factors among pregnant women in China: A systematic review and meta-analysis

BACKGROUND

Physical activity during pregnancy has been recommended as an effective measure to prevent various pregnancy complications. However, global physical activity participation during pregnancy is not optimal, and the factors influencing physical activity participation during pregnancy need to be further investigated. In China, where there are no localized guidelines for physical activity during pregnancy, the prevalence of meeting recommended physical activity levels among Chinese pregnant women is still unclear.

OBJECTIVES

This study aimed to comprehensively review the prevalence of meeting recommended physical activity levels among pregnant women in China and to further explore the factors influencing physical activity participation during pregnancy.

DESIGN

This was a systematic review and meta-analysis.

METHODS

A systematic review was conducted in both English and Chinese databases from inception until August 1, 2023. Two reviewers independently screened literature, assessed study eligibility and extracted data. The Agency for Healthcare Research and Quality was used to evaluate methodological quality of included studies. The pooled prevalence was calculated using a random-effects model. Subgroup analyses were conducted to explore sources of heterogeneity.

RESULTS

A total of 12 cross-sectional studies, including 11,323 Chinese pregnant women with a mean age ranging from 27.0 to 33.0 years, met the inclusion criteria. The prevalence of meeting recommended physical activity levels among pregnant women in China was 21.0 % (95 % confidence interval (CI):12.5 %-29.5 %). A higher prevalence of meeting recommended physical activity levels was observed among pregnant women who were in their second trimester, who were living in the southern region, who were assessed by validated questionnaires, and who used 150 min physical activity per week as a criterion for meeting recommendation.

CONCLUSIONS

The findings suggested a low prevalence of meeting recommended physical activity levels among Chinese pregnant women, which was affected by a variety of factors. It is recommended that further research be conducted in the future to explore physical activity intervention strategies for women of childbearing age before and during pregnancy based on the factors affecting physical activity to improve physical activity compliance, maternal and child health and population quality.

Nausea and vomiting in pregnancy (NVP) in Chinese pregnant women: a cross-sectional study

BACKGROUND

This study addresses the scarcity of research on nausea and vomiting in pregnancy (NVP) in China. It aims to explore the current NVP status in the country using validated questionnaires, analyze associated factors, and provide a useful reference for future research. The study also compares results from different assessment tools.

METHODS

Online questionnaires were utilized to gather data from 535 pregnant women across 24 provinces. Demographic, pregnancy, and NVP-related information were collected. NVP severity was assessed using Pregnancy-Unique Quantification of Emesis and Nausea (PUQE) and the Rhodes Index of Nausea, Vomiting, and Retching (RINVR) scales. Ordinal logistic regression identified factors linked to NVP severity. Differences between PUQE and RINVR assessments were compared.

RESULTS

NVP prevalence exceeded 90%, with 96.1% assessed by PUQE and 90.8% by RINVR. Incidence decreased from nausea to retching and vomiting. Severe NVP correlated with reduced gestational weight gain, younger age, fewer gestational weeks, and living in North (all P values < 0.05). There was moderate consistency between PUQE and RINVR assessments. The NVP prevalence assessed by the PUQE is higher than that assessed by the RINVR in the same population. However, the proportion of NVP levels above moderate assessed by RINVR is greater than that assessed by PUQE.

CONCLUSIONS

NVP is highly prevalent among Chinese pregnant women, with nausea being predominant. RINVR assessments may be better able to identify severe NVP, thereby improving the low treatment rates for severe NVP.

Critical windows of greenness exposure during preconception and gestational periods in association with birthweight outcomes

Few studies have examined the association between greenness exposure and birth outcomes. This study aims to identify critical exposure time windows during preconception and pregnancy for the association between greenness exposure and birth weight. A cohort of 13 890 pregnant women and newborns in Shanghai, China from 2016-2019 were included in the study. We assessed greenness exposure using Normalized Difference Vegetation Index (NDVI) during the preconception and gestational periods, and evaluated the association with term birthweight, birthweight z-score, small-for-gestational age, and large-for-gestational age using linear and logistic regressions adjusting for key maternal and newborn covariates. Ambient temperature, relative humidity, ambient levels of fine particles (PM2.5) and nitrogen dioxide (NO2) assessed during the same period were adjusted for as sensitivity analyses. Furthermore, we explored the potential different effects by urbanicity and park accessibility through stratified analysis. We found that higher greenness exposure at the second trimester of pregnancy and averaged exposure during the entire pregnancy were associated with higher birthweight and birthweight Z-score. Specifically, a 0.1 unit increase in second trimester averaged NDVI value was associated with an increase in birthweight of 10.2 g (95% CI: 1.8-18.5 g) and in birthweight Z-score of 0.024 (0.003-0.045). A 0.1 unit increase in an averaged NDVI during the entire pregnancy was associated with 10.1 g (95% CI: 1.0-19.2 g) increase in birthweight and 0.025 (0.001-0.048) increase in birthweight Z-score. Moreover, the associations were larger in effect size among urban residents than suburban residents and among residents without park accessibility within 500 m compared to those with park accessibility within 500 m. Our findings suggest that increased greenness exposure, particularly during the second trimester, may be beneficial to birth weight in a metropolitan area.

Physical activity trajectory during pregnancy and associations with maternal fatigue using a growth mixture modeling approach

The purpose of this study was to investigate the associations of physical activity trajectories with maternal fatigue. Pregnant women provided objectively assessed physical activity data by Pregnancy Physical Activity Questionnaire four times. Fatigue scale-14 was used to assess fatigue during pregnancy. Growth mixture modelling characterized physical activity trajectories across pregnancy. The generalized estimating equations was used to analyze the relationship between different physical activity profiles and fatigue in pregnant women. A total of 626 pregnant women were included in analysis in a teaching hospital in Nantong city. Fatigue (total, mental and physical) was not different between two groups based on total energy expenditure of PA (constantly high vs. constantly low). The pregnant women in "constantly high household PA" group had the higher fatigue compared to "constantly low household PA" (P < 0.05) and "constantly medium household PA" (P < 0.05). The pregnant women in "constantly high sport PA" group had lower fatigue compared to "constantly low sport PA" (P < 0.05). Household PA and sport PA were still an independent influencing factor for fatigue after controlling for confounding variables. Specifically, we observed that higher household PA and lower sport PA were associated with higher fatigue during pregnancy.

Attitudes and Barriers to Physical Activity and Exercise Self-Efficacy Among Chinese Pregnant Women: A Cross-Sectional Study

Background

Most pregnant women do not reach the recommendation for physical activity (PA). As a subcategory of PA, exercise is also essential. Evidence on pregnant women's attitudes and barriers to PA and exercise self-efficacy in China is scarce.

Aim

To explore the levels and influencing factors of attitudes and barriers to PA and exercise self-efficacy among pregnant women.

Methods

A cross-sectional study of 311 pregnant women was conducted from August to December 2022. Individual characteristics, pregnant women's attitudes toward exercise, barriers to prenatal PA and exercise, and exercise self-efficacy were measured using the self-designed demographic questionnaire, pregnant women's attitudes toward exercise questionnaire, barriers to prenatal PA and exercise questionnaire, and the pregnancy exercise self-efficacy scale, respectively.

Results

More than 90% of pregnant women believed exercise benefits themselves and their babies, and 40.8% of pregnant women did not know how to exercise. Women encounter different types of barriers to PA and exercise. Intrapersonal barriers included the proportion of feelings of tiredness (56.6%), low energy (54.7%), lack of interest or motivation (49.2%), feelings of illness and morning sickness (46.6%), and large body weight (43.7%). Interpersonal barriers included pregnant women being advised to avoid PA and exercise (49.2%), lack of clear advice about the intensity and dose of exercise (41.8%), no one to exercise with (38.9%), and lack of advice from healthcare professionals (38.6%). Weather conditions were the most significant environmental barriers (41.2%). The total score of pregnancy exercise self-efficacy was (38.50±7.33). Education level, parity, and attitudes toward exercise independently predict pregnant women's attitudes toward exercise, barriers to prenatal PA and exercise, and exercise self-efficacy, respectively.

Conclusion

Pregnant women have a favorable attitude toward exercise and relatively good exercise self-efficacy but lack knowledge of exercise. They face numerous barriers. Medical professionals should encourage pregnant women with lower levels of education to exercise and assist multipara in overcoming obstacles.

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.

Development and feasibility of a theory-guided and evidence-based physical activity intervention in pregnant women with high risk for gestational diabetes mellitus: a pilot clinical trial

BACKGROUND

Physical activity has been utilized as an effective strategy to prevent gestational diabetes mellitus (GDM). However, most pregnant women with high risk for GDM did not achieve the recommended physical activity level. Furthermore, relevant physical activity protocols have varied without theory-guided and evidence-based tailored to pregnant women with high risk for GDM. This study aimed to develop and pilot test a theory-guided and evidence-based physical activity intervention protocol for pregnant women with high risk for GDM.

METHODS

The study design was guided by the Medical Research Council Framework for Developing and Evaluating Complex Intervention (the MRC framework). The preliminary protocol for physical activity intervention was developed based on self-efficacy theory, research evidence identified from systematic reviews and clinic trials, stakeholder engagement, context, and economic considerations. The preliminary intervention protocol was validated through a content validity study by an expert panel of 10 experts. A single-blinded randomized controlled trial (RCT) was designed to test the feasibility and acceptability of the intervention.

RESULTS

The validity of the preliminary intervention protocol was excellent as consensus was achieved. The final 13 sessions of self-efficacy enhancing physical activity intervention protocol were developed, including knowledge education, exercise clinic visits and video, and group discussions with face-to-face and online blended sessions. In the feasibility study, 34 pregnant women with high risk for GDM were randomized for the intervention (n = 17) or the control group (n = 17). The recruitment and retention rates were 82.9% and 58.9%, respectively. Women in the intervention group had a lower incidence of GDM (26.7% vs. 36.5%) than the control group (P >0.05). All participants were satisfied with the intervention and agreed that the intervention was helpful.

CONCLUSIONS

The developed self-efficacy-enhancing physical activity intervention is a feasible and acceptable intervention for enhancing physical activity among pregnant women with high risk for GDM and is ready to be tested in a more extensive RCT study.

TRIAL REGISTRATION

The study was registered on 4 February 2022 (ChiCTR2200056355) by the Chinese Clini Trial Registry (CHiCTR).
