Data on how the complex cognitive processes, personal, and social factors influence health promoting behaviors of women are very limited and the results have been inconsistent. Here, we examine how prior behaviors, behavior-specific cognition (perceived benefits/barriers, self efficacy, and activity-related affect), situational and interpersonal factors (social support, modeling, and norms) associated with the level of dietary behaviors in Iranian women. A cross sectional survey of 356 women aged 18–60 years from health care centers in Iran was undertaken from October 2015 to September 2016. Multiple analytical models and Pender’s health promotion model (HPM) were implemented to examine the effectiveness of HPM and its potential constructs on PA behaviors. The instruments used were designed using Pender’s HPM as a basis. The path model fitted data and accounted for 51% of the variance in dietary behaviors; and prior behavior, perceived self-efficacy, interpersonal influences, and commitment to plan were significantly associated with dietary behavior. We found that constructs from the HPM are empirically improved dietary behavior among the women population. This result provides a suitable source for designing strategies of a nutrition education intervention for improving the frequency and nutrient intake of breakfast consumption among female students.
Background This study examined how socio-demographic characteristics constructs derived from the health promotion model (HPM) influence the level of physical activity (PA) women in Bojnourd, North East of Iran. Method This cross-sectional study has been carried out through multi-stage sampling design on 356 women aged 18–60 years living in Iran. Data was collected through reliable and valid questionnaire survey women who were selected from their homes. Results Most of participants (53.40%) had a low level of physical activity behaviors with minimal physical activity (PA) scores. Using regression analysis showed that 23.22% of the total variance in PA behaviors was predicted by socio-demographic variables, whilst 40.81% of the variance in PA behaviors was predicted by constructs from the HPM. The results from Path modeling indicated that prior behavior, interpersonal influences, perceived self-efficacy, perceived barriers and commitment to PA, were significant predictors for PA behaviors with 86.93% of total effects on PA, whereas, activity-related affect and situational influences had no significant effect on the PA behaviors. Conclusions We found that constructs derived from the HPM are determinants of PA among Iranian women and may be important in developing educational intervention programs to facilitate a physically active lifestyle in this population.
Objective: The relative contribution of health promotion models to improve health-related behaviors in intervention programs are still limited. Here, we tested whether Pender’s health promotion model (HPM) operationalized in the educational intervention was effective to modify nutrition and physical activity (PA) behaviors among Iranian women. Design: A randomized controlled field trial evaluating the efficacy of an educational intervention based on Pender’s HPM to improve PA and nutrition behaviors from August 2016 to October 2016. R version 3.0.2 and SPSS version 16 were used to conduct multiple statistical analyses. Setting: Ten public healthcare centers in Bojnourd, Iran were randomly divided into intervention and control groups. The experimental group received the full intervention program, which included nine 4-hours training sessions and consulting support via phone contact and social media group. The control group did not receive any intervention. Participants: Women aged 4–6 years (n 202) were randomized to intervention (n 102) and control conditions (n100), and completed baseline and 3-months follow-up. Results: In the experimental group, the intervention program had a significant effect (p < 0.05) on all construct of Pender’s HPM and behavior outcome, and the estimate (95% CI) for prior behaviors, self-efficacy, interpersonal influences, feeling, perceived benefits and barriers, commitment, and behaviors outcomes in the intervention group were 0.72 (0.31-0.98), 0.54 (0.27-0.71), 0.74(0.27-0.91), 0.52(0.19-0.75), 0.62 (0.22-0.91), 0.63(0.30-0.86), and 0.56 (0.37-0.85), respectively. Conclusions: Educational intervention based on Pender’s HMP was feasible and highly acceptable to modify PA and nutrition behaviors in the women population.
