Impact of a healthy lifestyle intervention program during pregnancy on women and newborn: STUDY PROTOCOL for a quasi-experimental study

Effect of Evidence-Based Materials and Access to Local Resources on Physical Activity Levels, Beliefs, and Motivation During Pregnancy in a Rural Setting

BACKGROUND

The purpose of this study was to determine the impact of evidence-based educational materials and access to local resources on physical activity (PA) levels, beliefs, and motivation (including self-efficacy) regarding PA during pregnancy in a rural setting.

METHODS

Information on PA levels (step counts, Pregnancy Physical Activity Questionnaire) and beliefs and motivation regarding PA (main surveys: Exercise Beliefs Questionnaire, Protection Motivation Theory and Health Action Process Approach) were collected between 8 and 16 weeks gestation. Women from a rural community were randomly assigned to the PA group (PAG, n = 38) or control group (n = 32). The PAG participants received an evidence-based educational brochure and access (at no charge to them) to local fitness facilities. At approximately 34 to 37 weeks gestation, baseline assessments were repeated.

RESULTS

Sedentary time was significantly different between groups over time, with control participants increasing sedentary time and PAG participants decreasing sedentary time (P = .04). Sixteen women (42%) in the PAG utilized the resources provided (prenatal yoga being utilized most). Postintervention, there was a significant group × time interaction for Perceived Self-Efficacy scores; scores in the PAG remained consistent with baseline values, whereas scores in the control group decreased (P = .03).

CONCLUSIONS

The intervention reduced sedentary time and maintained self-efficacy scores during pregnancy.

Predictors of Health-Promoting Lifestyle in Pregnant Women Based on Pender's Health Promotion Model

Background and Objectives

Pregnancy causes changes in women’s lifestyle; therefore, their health-promoting behaviors should be improved in order to avoid problems during this critical period, which requires knowledge of the factors affecting these behaviors. This study was conducted to determine the predictors of health-promoting lifestyles in pregnant women based on Pender’s health promotion model constructs.

Methods

This descriptive study was carried out on 300 pregnant women in their second and third trimesters of pregnancy and sought to determine the correlation between lifestyle and the constructs of Pender’s health promotion model. Data were collected using a demographic questionnaire, the Health Promoting Lifestyle Profile II (HPLP-II) and a questionnaire based on Pender’s model constructs. Data were analyzed using descriptive and analytical statistics.

Findings

A health-promoting lifestyle had a significant positive correlation with the constructs of social support and perceived benefits and a significant negative correlation with the construct of perceived barriers (P<0.05). A health-promoting lifestyle also had a significant relationship with the constructs of perceived barriers, social support and perceived benefits in pregnant women (P<0.05) based on the results of the regression analysis. The regression coefficients showed that all the three variables can significantly explain the variance in health promoting lifestyles in pregnant women (P<0.05).

Conclusion

According to the results of the present study and based on the constructs of Pender’s health promotion model, social support, perceived benefits and perceived barriers were the most important predictors of health-promoting lifestyles in pregnant women. These predictor constructs are recommended to be further considered in designing and implementing training packages and interventions for promoting pregnant women’s lifestyle.
