Using the Theory of Planned Behavior to predict pregnant women's intention to engage in regular exercise

Physical activity during pregnancy: key beliefs to support intervention

Background

Physical activity (PA) provides maternal and fetal health benefits, but only 27.5% of Canadian pregnant women meet PA recommendations. Theory-based interventions like the theory of planned behavior (TPB) are useful in explaining what drives behavior. The first objective of this study was to validate the TPB model to predict prenatal moderate-to-vigorous physical activity (MVPA), including testing of the novel interaction between intention and perceived behavioral control (PBC). The second objective was to identify which specific beliefs predict intention toward prenatal MVPA to support intervention.

Method

We used a prospective correlational design. Healthy pregnant women completed two electronic questionnaires: at baseline, to assess TPB constructs, and one month later, to assess MVPA practice. Structural equation modeling was conducted with Latent Moderated Structural Equations. The interaction was interpreted with the pick-a-point method and the Johnson-Neyman graphical method.

Results

The sample consists of 193 women (M age = 31.2±3.6). Results indicate that prenatal MVPA at one month was marginally predicted by intention (β = 0.149; p < 0.10) and PBC (β = 0.322; p < 0.05, MVPA R 2 = 20%), but when their interaction was added to the model, MVPA R 2 increased to 44%. Specifically, the relationship between intention and MVPA is stronger when PBC is high (0.5 standard deviation over the mean). In the full model including the interaction, attitude (β = 0.59; p < 0.001), subjective norm (β = 0.20; p < 0.01) and PBC (β = 0.26; p < 0.05) all made a significant contribution to predicting MVPA intention (R 2  = 88%). Finally, the following beliefs displayed significant indirect paths toward the intention of being physically active: behavioral beliefs: unlikely to be more tired and likely feel better mentally; normative beliefs: approval from friends and from mother/father; and control beliefs: being tired and missing social support.

Conclusion

Interventions aiming to promote regular MVPA during pregnancy should prioritized the six significant beliefs identified to significantly predict intention toward prenatal MVPA.

Fertility education: recommendations for developing and implementing tools to improve fertility literacy†

Many recent societal trends have led to the need for fertility education, including the age at which individuals become parents, the development of new reproductive technologies, and family diversity. Fertility awareness has emerged as a concept very recently and is increasingly gaining recognition. However, fertility education is often neglected as there is no consensus on the appropriate content, target populations, or on who should provide it. This article attempts to provide an overview of the use of interventions to improve fertility education. We emphasize the importance of delivering evidence-based information on fertility and reproductive health through various methods while providing guidelines for their standardization and systematization. Recommendations are provided to aid the development and implementation of fertility education tools, including: the establishment of a comprehensive understanding of the target populations; the incorporation of theories of behavioural change; the inclusion of the users' perspectives and the use of participatory research; and the use of specific guidelines for increasing engagement. By following these recommendations, it is expected that fertility education resources can contribute to improving fertility literacy, empowering individuals and couples to make informed reproductive decisions, and ultimately reducing the incidence of infertility and need for fertility treatment.

Exercise Intention and its Associated Factors Among Persons Post-Stroke: A Cross-Sectional Study

Purpose

To investigate the level of exercise intention and its associated factors among persons post-stroke using the Theory of Planned Behavior.

Patients and Methods

In this cross-sectional study, a total of 333 participants admitted to the neurology units of a tertiary care hospital in China with a confirmed diagnosis of stroke were recruited. A self-administered instrument based on the Theory of Planned Behavior was used to determine the exercise intention and its associated factors among persons post-stroke.

Results

The results revealed that only 128 participants had exercise intention after discharge with a prevalence of 38.4%. Multivariable linear regression analysis revealed that monthly income, living situation, subjective norms, attitude, and perceived behavioral control were significant predictors of exercise intention of persons post-stroke. Perceived behavioral control and living situation were the most relevant factors of exercise intention.

Conclusion

The level of exercise intention among persons post-stroke was found to be low. Perceived behavioral control and living situation were particularly important and contributed to exercise intention. Healthcare professionals' adequate guidance on exercise should be provided, with a focus on educating both patients and their family members, especially spouses, to promote exercise intention in persons post-stroke.

Predicting Physical Activity in Chinese Pregnant Women Using Multi-Theory Model: A Cross-Sectional Study

BACKGROUND

Physical activity (PA) brings many benefits to pregnant women and fetuses; however, the majority of pregnant women do not participate actively in PA during pregnancy.

OBJECTIVES

This study aimed to: (1) assess the utility of Multi-Theory Model (MTM) to explain the intentions of PA behavior in Chinese pregnant women; (2) analyze the predictors in initiating and maintaining PA behavior based on MTM.

METHODS

A cross-sectional study including pregnant women was conducted from March to June 2022 at a university hospital in Hangzhou, Zhejiang Province, China. Participants completed measures that included a self-developed demographic questionnaire and a 29-item MTM questionnaire. Descriptive statistics and stepwise multiple regression were used to analyze the data. The reliability was assessed by Cronbach's alpha and test-retest stability. The construct validity was evaluated by using exploratory factor (EFA) analysis and confirmatory factor analysis (CFA).

RESULTS

A total of 450 pregnant women participated in this study. The score of the magnitude of intention to initiate and maintain PA behavior during pregnancy was 2.30 (1.08) and 2.24 (1.09). The overall Cronbach's alpha value was 0.857. A four-factor structure for initiation model and a three-factor structure for maintenance model were determined. Results of the CFA confirmed construct validity of subscales (initiation model: χ² = 206.123, df = 140, p < 0.001, χ²/df = 1.472, RMSEA = 0.046, SRMR = 0.0432, GFI = 0.913, CFI = 0.982; maintenance model: χ² = 49.742, df = 29, p < 0.001, χ²/df = 1.715, RMSEA = 0.057, SRMR = 0.0432, GFI = 0.958, CFI 0.985). The result of regression indicated that participatory dialogue (β = 0.030; p = 0.002), behavioral confidence (β = 0.128; p < 0.001), changes in physical environment (β = 0.041; p = 0.005), trimester (β = -0.192; p = 0.001), and Gestational Diabetes Mellitus (GDM) (β = 0.408; p < 0.001) explained 52.1% variance in initiating PA behavior. Emotional transformation (β = 0.197; p < 0.001), practice for change (β = 0.083; p = 0.001), changes in social environment (β = 0.063; p < 0.001), pre-pregnancy exercise habit (β = -0.251; p = 0.001), and GDM (β = 0.298; p = 0.003) were significantly associated with pregnant women's intentions to maintain PA behavior and explained 49.1% variance.

CONCLUSIONS

The constructs of MTM were effective in explaining the intention to initiate and maintain PA behavior among Chinese pregnant women.

Physical exercise and its associated factors among Ethiopian pregnant women: a cross-sectional study based on the theory of planned behavior

INTRODUCTION

Women in Ethiopia prefer sedentary behavior and are physically inactive during pregnancy; this increases the risks of pregnancy-related complications. Therefore, this study aimed to assess physical exercise and its associated factors among pregnant women attending Antenatal Care at Debermarkose Referral Hospital, Northwest Ethiopia: using the theory of planned behavior.

METHODS

An institution-based cross-sectional study was conducted from 23rd February to 10th June, 2020. A systematic random sampling technique was used to select 333 study participants. Data were collected with face-to-face interviews using a pretested structured questionnaire. Epi-info and STATA version 14.0 were used for data entry and analysis respectively. Multivariable linear regression analysis was done to identify the association between dependent and independent factors, and p < 0.05 was used as a cutoff to determine statistical significance at multivariable logistics regressions.

RESULT

A total of 333 pregnant women were participated in this study with response rate of 98%. The proportion of variance (R2) in intention accounted for the factors was 0.79. The magnitude of intention to do physical exercise during the current pregnancy was 3.8 ± 2. primary level of education (β = 0.43; 95% CI 0.25, 0.61), 2nd trimester gestational age (β = 0.19; 95% CI 0.04, 0.33), 3rd trimester gestational age (β = 0.17; 95% CI 0.02, 0.32), Attitude (β = 0.34; 95% CI 0.19, 0.49), subjective norm (β = 0.12; 95% CI 0.01, 0.23) and perceived behavioral control (β = 0.45; 95% CI 0.33, 0.57) were significantly associated with pregnant womens' intention to do physical exercise during pregnancy period.

CONCLUSION AND RECOMMENDATIONS

This study provided that the theory of planned behavior could be successfully applied to identify the factors related to the intention to do physical exercise during pregnancy The program designers who work on pregnancy better consider providing Information education and communication to change the attitude, work on influencing significant individuals and barriers and enabling factors.

The theory of planned behavior and strength training in college-aged women

ObjectivesUsing Theory of Planned Behavior, the objective of this study was to determine how attitudes, subjective norms and perceived behavior control related to intent to strength training by college-aged women. Participants: Participants were college-aged females (N = 162) from a mid-sized private university in the Midwestern United States who were divided into three groups: non-exercisers, cardiovascular-only exercisers, and strength or strength and cardiovascular exercisers. Methods: Participants completed a questionnaire assessing attitudes, subjective norms and perceived behavior control in relation to strength training behavior. MANOVA was utilized to examine the differences between groups. Results: The MANOVA was significant at p < .01. Post hoc analysis indicated strength training participation was significantly higher for non-exercisers and cardiovascular-only exercisers for the attitude and perceived behavior control constructs (p<.05) but not for subjective norm. Conclusions: Perceived behavior control and direct attitude factors may be strong contributors to college-aged women's participation in strength training.

Development of an exercise attitude scale in Turkish for pregnant women: validity and reliability

This study, conducted between October 2018 and May 2019, aimed to develop an Exercise Attitude Scale in Turkish (EAS-Turkish) for pregnant women and to determine its validity and reliability. The scale was prepared in Turkish to comprehensively measure pregnant women's exercise attitudes. Then, it administered in 253 pregnant women, who were native speakers of Turkish and older than 18 years, in the Obstetrics Polyclinic at Ataturk Training and Research Hospital, Ankara, Turkey. Validity with exploratory and confirmatory factor analysis and reliability with test-retest and internal consistency methods were tested. The 37-item scale was found to be 2-dimensional (knowledge and benefit; barrier). All indexes of the goodness of fit (χ2/df = 2.0, Comparative Fit Index = 0.90, Goodness-of-fit Index = 0.85, Root Mean Square Error of Approximation = 0.06) indicated that the fit between the model and the sample data was acceptable. The item-total score correlations varied between r = 0.22 and 0.60. The Cronbach alpha coefficients were found as 0.90 for the whole scale, 0.91 for the knowledge and benefit sub-dimension, and 0.87 for the barrier sub-dimension. In the test-retest analysis conducted with 41 pregnant women, the reliability coefficients were detected as 0.93 for the whole scale and 0.84 for each sub-dimension. The EAS-Turkish for pregnant women was found to be a valid and reliable tool.

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

BACKGROUND

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

AIM

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

DESIGN

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

METHODS

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

RESULTS

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

LINKING EVIDENCE TO ACTION

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

Application of Implementation Science to OB/GYN Quality Improvement Efforts

Although there is no shortage of guidelines and toolkits outlining clinical practices that are evidence-based and have been shown to improve outcomes, many hospitals, and L&D units struggle to figure out exactly how to implement strategies that have been shown to work. This paper will describe suggestions to help obstetrics and gynecology units successfully implement evidence-based strategies to improve quality and safety based on the theoretical framing structures of implementation science, including theories such as the Health Beliefs Model, the Theory of Planned Behavior, Ecological Perspectives, COM-B, CFIR, and tools such as Driver Diagrams.

Effectiveness of individual face-to-face exercise counselling in changing exercise behaviours to relieve symptom distress in pregnant women

AIM

The present study aimed to evaluate the effectiveness of individualized exercise counselling in changing exercise behaviour and relieving pregnancy-related distress symptoms in pregnant women.

METHODS

A quasi-experimental design and convenience sampling technique were used. Participants were recruited from the prenatal outpatient departments of medical centre hospitals in Taipei, Taiwan. The experimental group (n = 52) received face-to-face exercise counselling followed by 8 weeks of exercise sessions in their homes. The control group (n = 49) received no exercise counselling. Pregnancy-related distress symptoms were assessed before and after 8 weeks in both groups.

RESULTS

The after-counselling scores of total (t = 2.46, P < 0.05) and physical (t = 3.18, P < 0.01) distress symptoms were significantly lower than the before-counselling scores in the experimental group. The total, physical and psychological distress scores significantly differed between groups and before and after counselling. The adjusted R² values for total, physical and psychological distress symptoms ranged from 0.59 to 0.70. Participants' exercise habits increased from prepregnancy (19.2%) to after counselling (71.2%).

CONCLUSION

Exercise counselling may effectively increase exercise habits and reduce pregnancy-related distress symptoms among pregnant women. Women with higher pretest symptom distress scores also had higher posttest symptom distress scores. Based on our outcomes, health care providers should routinely provide exercise counselling to pregnant women.

The intention to undertake physical activity in pregnant women using the theory of planned behaviour

AIM

To identify the intention of Chinese pregnant women to undertake physical activity (PA) using the theory of planned behaviour.

DESIGN

A cross-sectional survey.

METHODS

From April - October 2017, a cross-sectional questionnaire was completed by 746 pregnant women from the Health Birth Cohort in Wuhan, China. The theory of planned behaviour variables as well as sociodemographic characteristics was recorded, and the Pregnancy PA Questionnaire was together used to assess their PA during pregnancy.

RESULTS

Only 11.3% of the women met the international guideline. The intention to undertake PA was found it to be positive in 63.9% of pregnant women. Structural equation modelling analysis revealed that behavioural attitudes, subjective norms, and perceived behavioural control (PBC) influenced PA by directly influencing the behaviour intention. Both behavioural attitude and subjective norms influenced PA by indirectly affecting the behaviour. Overall, the model described 60% variance of the behavioural intention to undertake PA during pregnancy.

CONCLUSION

PBC was confirmed to be a prominent factor in determining behavioural intention to undertake PA during pregnancy. Pregnant women should be helped and appropriately guided by health providers to overcome barriers to PA.

EFFECT

This study investigates the effect of perceived behavioural control (PBC) on the intention to undertake physical activity (PA). The findings suggest that nurses' and midwives' attention should be focused on how to promote the improvement of perceived behavioural control ability of pregnant women to improve pregnant women's PA intention. The attitude of pregnant women on taking up PA and their ability to control behaviours can be improved with support from family or healthcare providers.

Constructing and applying an exercise counseling model for pregnant women: A preliminary study

Pregnant women tend to exercise less than women who have not yet been pregnant. In the present study, which involves two studies, we aimed to construct an effective, individualized exercise counseling model for pregnant women. In study 1, a three-round session that involved 10 multidisciplinary health care experts reached a consensus via the Delphi method. In the preliminary study, two healthy pregnant women were recruited from the prenatal outpatient departments of hospitals in Taipei, Taiwan. Both of them were 32 years old and primipara. The results of study 1, the established five stages of the individualized exercise counseling model for pregnant women were as follows: assessment, defining barriers that interfere with achieving the target, planning, implementation and monitoring, and evaluation. In the preliminary study, we applied this counseling model of study 1 to 2 healthy pregnant women. The 5-stage counseling model can encourage pregnant women to begin to exercise or to continue exercising. We believe that this exercise counseling model can potentially be used by nurses. It can help them to encourage pregnant women to regularly exercise, and to promote exercise as part of a healthy lifestyle.

Physical Activity, Functional Ability, and Obesity in Older Adults: A Gender Difference

Disability, institutionalization, and loss of independence may be directly caused or exacerbated by physical inactivity and obesity. The purpose of the current cross-sectional survey was to explore the impact of gender and obesity on functional ability tasks, physical activity, and psychosocial factors in older adults. Participants comprised 964 University retirees (55% female, mean age = 75.3 years, SD = 6.7 years) with a mean body mass index (BMI) of 26.1 kg/m² (SD = 4.7 kg/m²). Results revealed significant gender and BMI interaction effects. Women were less active than men and obese women were most functionally impaired, particularly in activities that target lower extremity function, regardless of weight status. These findings suggest that physical activity interventions for older adults should focus on exercises that improve functional ability and are tailored to meet individual needs while considering weight and gender. Type, intensity, frequency, and duration of exercises should be individualized to limit injuries and improve functional ability and physical activity adherence.
