Abstract

Abstract: Objectives: The objective of this study was to assess the effect of a nutrition education intervention (NEI) on increasing dietary calcium intake among Vietnamese women aged 30–65 years in rural Hanoi, Vietnam. Methods: This study used pretest/posttest experimental and delayed nutrition intervention approach. The NEI was based on the Health Belief Model and comprised two educational and demonstrations sessions, followed by educational handouts once a week for 4 weeks. Women aged 30–65 years in six communities in a rural district in Hanoi were recruited and randomly assigned into two groups: intervention group (IG, n = 128), which received the NEI first, and a control group (DG, n = 118), that received a delayed intervention. Dietary calcium intake, knowledge, health beliefs, and self-efficacy were collected at baseline/pre-intervention and post-intervention. Linear mixed model with repeated measures and multiple regression were used to assess the effectiveness of the nutrition intervention. Results: The results showed that participants in the IG had a significant higher increase in knowledge score at post intervention, compared to the DG (4.02 points larger, P < 0.05). Perceived susceptibility and barriers significantly decreased from baseline to post intervention in the IG ( P ≤ 0.001). From baseline to post intervention, self-efficacy significantly increased among participants in the IG ( P < 0.05) whereas the DG significantly decreased their self-efficacy ( P < 0.05). While calcium intake at baseline was not significantly different between the IG and DG, at post intervention the IG reported a significant higher increase in calcium intake than the DG ( P < 0.05). Regression analysis showed that knowledge and self-efficacy significantly predicted dietary calcium intake ( P ≤ 0.001). Conclusions: Findings of this study demonstrate the importance of nutrition education in increasing dietary calcium intake and knowledge among Vietnamese women. The findings also suggested that knowledge and self-efficacy played an important role in improving dietary calcium intake.
