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

Facilitators and barriers of initiation and maintenance of physical activity among people with coronary heart disease: a qualitative study

PURPOSE

We aimed to describe the facilitators and barriers of physical activity for patients with coronary heart disease.

METHODS

A qualitative descriptive study using semi-structured interviews was conducted with 15 participants with coronary heart disease. The interview guide was developed based on a multi-theory model. Interviews were audio-recorded, transcribed verbatim, and analyzed using a thematic analysis.

RESULTS

Two main themes were identified: facilitators of initiation and maintenance of physical activity (behavioral motivation, perceived benefits, behavioral confidence, supportive physical environment, positive emotional experience, self-regulation, supportive social environment, illness perception, and excellent self-control), barriers of initiation and maintenance of physical activity (perceived barriers, restricted physical environment, psychological distress, insufficient social support, and poor self-control).

CONCLUSIONS

This study presents an in-depth theory-based exploration of facilitators and barriers to initiating and maintaining physical activity among people with coronary heart disease. Relevant factors should be taken into account to increase their effectiveness when designing the target interventions to encourage a physically active lifestyle in this population.

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.

Developing a Theory-Based Instrument for Pre-Exposure Prophylaxis (PrEP) Uptake in People of Color Using a Qualitative Approach

There is a large disparity in Pre-exposure Prophylaxis (PrEP) utilization among communities of color compared to White Americans. There is also a lack of theory-based survey instruments to measure the underlying reasons for the disparity among communities of color. The purpose of this study was to create an instrument based on a qualitative approach involving community interviews. Semi-structured interviews guided by the Multi-theory Model (MTM) of health behavior change were performed in a sample of 12 members from communities of color. The analysis entailed a directed content analysis along the themes of MTM constructs to develop a survey instrument. The barriers to PrEP that emerged included the cost of PrEP, lack of protection from other sexually transmitted diseases, reduced trust between partners, and the stigma associated with PrEP. The perceived disadvantages included the potential cost of PrEP, partner mistrust when taking PrEP, discussion of sexual behaviors with a provider, and unclear process of acquiring the PrEP prescription. The results guided the development of a survey tool to further investigate aspects of cost, partner relations, stigma, reassurance of safety, and other factors. The tool can be used for future studies as part of guided interventions to increase PrEP uptake.

Utilization of the multi-theory model (MTM) of health behavior change to explain health behaviors: A systematic review

Background

The utilization of a theoretical framework is vital in health promotion research, particularly when endeavoring to modify health behaviors. This systematic review aimed at evaluating and synthesizing evidence through studies conducted using the fourth-generation multi-theory model (MTM) of health behavior change for its effectiveness.

Methods

A comprehensive article search was performed across MEDLINE, CINAHL, and Academic Search Premier. The search focused on studies utilizing MTM from 2016 to December 2023, following the PRISMA guidelines for systemic reviews.

Results

An initial pool of 7583 articles was narrowed down through screening of titles, abstracts, and full texts. A total of 69 articles met the inclusion criteria. These studies, encompassing a global range of diverse target groups and health behaviors, were categorized as qualitative, cross-sectional, or experimental. The six qualitative studies revealed MTM themes for diverse health behaviors. The fifty-six cross-sectional studies showed MTM constructs effectively predicting behavior change, albeit with varying statistical significance. The seven experiments demonstrated MTM's role in initiating and sustaining change. For the initiation model, operationalized by 49 studies, the mean adjusted R2 was 38.4% (SD=16.4%). For the sustenance model, operationalized by 45 studies, the mean adjusted R2 was 38.9% (SD=15.5%).

Conclusion

This systematic review corroborates the MTM as a potent framework for understanding, predicting, and facilitating health behavior changes. Its universal applicability and effectiveness underscore the model's potential as a foundational tool in designing future health promotion strategies and interventions aimed at positive and enduring behavior modifications.

Theory-based antecedents of breastfeeding among pregnant women in the United States

Background

Breastfeeding provides several positive health benefits for the newborn child, yet breastfeeding rates remain low in the United States (US). Theory-based approaches have the potential to improve breastfeeding promotion interventions. Hence, the study examined the correlates of intention to breastfeed among US pregnant women based on the multi-theory model (MTM) of health behavior change.

Methods

Using a cross-sectional design, a 36-item online survey was administered to a nationally representative sample of 315 pregnant women in the US. The instrument was psychometrically validated for face, content, and construct validity by a panel of six experts over two rounds. Further, construct validation was done by confirmatory factor analysis (CFA). Hierarchical regression modeling was employed to explain the intention to start breastfeeding and sustain exclusive breastfeeding for up to six months and with complementary foods for up to 24 months.

Results

Internal consistency using Cronbach's alpha was found to be acceptable. It was found that behavioral confidence and changes in the physical environment positively affected the initiation of breastfeeding (P<0.01; adjusted R2=0.478). All three constructs of MTM namely practice for change, emotional transformation, and changes in the social environment were significant predictors for the sustenance of breastfeeding at six months (P<0.01; adjusted R2=0.591) and at 24 months (P<0.01; adjusted R2=0.347).

Conclusion

Based on the findings of this study it is essential for educators and healthcare providers to design MTM-based interventions to promote breastfeeding among pregnant women in the US.

Mini review: possible role of the multi-theory model of health behavior change in designing substance use prevention and treatment interventions

Many behavior change theories have evolved over time. Originally, the first conceptions prioritized interventions based on information, such as raising awareness and transferring knowledge. Second-generation theories prioritize the development of skills and the promotion of awareness. The emergence of evidence-based techniques in the 1990s gave rise to third-generation theories such as the Theory of Planned Behavior and Social Cognitive Theory. Presently, fourth-generation trends amalgamate various components from multiple theories to implement accurate treatments, employing technology and emphasizing targeted behavior change. This paper aims to do a concise evaluation of the multi-theory model (MTM) of health behavior change interventions in the context of planning substance use prevention and treatment. The current area of intervention programs aimed at preventing and treating substance use may benefit from MTM, an innovative fourth-generation behavior change model. Tobacco, alcohol, and other drugs have all been the subjects of experimental, cross-sectional, and qualitative research. We have presented that additional research is required to compare MTM with knowledge-based therapies or interventions grounded in other theories. A gold standard would be the randomized controlled trials and behavioral change interventions particularly useful for this purpose. In addition, research evaluating the interventions' efficacy must be carefully planned and executed.

Examining the Gambling Behavior of University Students: A Cross-Sectional Survey Applying the Multi-Theory Model (MTM) of Health Behavior Change in a Single Institution

Gambling among college students can start as a pastime activity. However, this pastime can lead to problem gambling and pathological gambling. This cross-sectional study aimed to identify and explain the initiation and sustenance of quitting gambling among university students who had participated in gambling during the past month and those who had not using a novel fourth-generation multi-theory model (MTM) of health behavior change. Data were collected from a sample of 1474 university students at a large southwestern university in the U.S. between January 2023 and February 2023, utilizing a validated 39-item survey. The statistical analyses employed in this study encompassed descriptive statistics, independent samples t-tests, and hierarchical regression modeling. Among students who had engaged in gambling in the past month, the constructs of participatory dialogue (β = 0.052; p < 0.05), behavioral confidence (β = 0.073; p < 0.0001), changes in the physical environment (β = 0.040; p = 0.0137), and demographic variables accounted for 27.7% of the variance in the likelihood of initiating the behavior change. Furthermore, the constructs of emotional transformation (β = 0.104; p = 0.0003) and practice for change (β = 0.060; p = 0.0368), and demographic variables accounted for 22.6% of the variance in the likelihood of sustaining quitting gambling behavior. The Multi-Theory Model (MTM) can be employed to design interventions aimed at reducing problem gambling among college students.

Exploring the Influencing Factors of COVID-19 Vaccination Willingness among Young Adults in China

Vaccine uptake is considered as one of the most effective methods of defending against COVID-19 (coronavirus disease 2019). However, many young adults are hesitant regarding COVID-19 vaccines, and they actually play an important role in virus transmission. Based on a multi-theory model, this study aims to explore the influencing factors related to COVID-19 vaccine willingness among young adults in China. Using semi-structured interviews, this study explored the factors that would motivate young adults with vaccine hesitancy to get the COVID-19 vaccine. Thematic analysis was used to analyze the interview data with topic modeling as a complementarity method. After comparing the differences and similarities of results generated by thematic analysis and topic modeling, this study ultimately identified ten key factors related to COVID-19 vaccination intention, including the effectiveness and safety of vaccines, application range of vaccine, etc. This study combined thematic analysis with machine learning and provided a comprehensive and nuanced picture of facilitating factors for COVID-19 vaccine uptake among Chinese young adults. Results may be taken as potential themes for authorities and public health workers in vaccination campaigns.

Factors associated with meeting the WHO physical activity recommendations in pregnant Colombian women

In the absence of medical contraindications, physical activity (PA) can offer health maternal and fetal health outcomes during pregnancy. However, most pregnant women may not consider PA to be feasible, suitable and safe. Hence, it is essential to determine the prevalence of pregnant women who meet the PA recommendations and the possible factors associated with that meeting, since it might be important from the perspective of pregnant women's health. The aim of the present study was to establish the prevalence of meeting the World Health Organization PA recommendations for Colombian pregnant women, as well as possible factors that may be associated with meeting that recommendations. A cross-sectional study including representative data from the National Nutritional Situation Survey (2015) in Colombia was performed. Data were collected in 2015-2016. From an initial sample of 1140 Colombian pregnant women, 702 participants with complete data were included in the final analysis. PA was assessed by self-reported information through the long version of the International Physical Activity Questionnaire. Several potential factors were analysed according to four levels of the socioecological model: the individual, interpersonal, organizational and community levels. The prevalence of Colombian pregnant women who met with the PA recommendations was 7.5%. Indigenous and Mestizo pregnant women showed lower probabilities of meeting the PA recommendations [Indigenous: OR 0.05, 95% CI (0.01-0.18); Mestizo: OR 0.12, 95% CI (0.06-0.22)] than Afro-Colombian participants. Additionally, participants who lived near green and safe spaces for PA were more likely to meet the PA recommendations [OR 2.30, 95% CI (1.06-4.79)] than those who did not live near green areas. In conclusion, a low percentage of Colombian pregnant women met the new PA recommendations. The associations found according to race/ethnicity and living near green and safe areas underline the presence of fundamental disparities associated with meeting PA recommendations.
