Unhealthy eating habits are an important cause of Non-communicable Diseases (NCDs). One of the most effective methods to prevent these diseases is the use of health education interventions. The aim of this study was to evaluate the effect of educational intervention performed by Women Health Volunteers (WHV) on knowledge, attitude, and modification of dietary habits among women in Kerman.


This research was a quasi-experimental study performed on 400 women in Kerman. Participants were selected using multistage cluster sampling. Data were collected immediately before and 6 weeks after the intervention by a questionnaire, including demographic information and questions related to knowledge, attitude, and dietary habits. Data were analyzed using Pearson and Spearman correlation, paired t-test, and Wilcoxon-test in SPSS 24.


The average age of women was 41.91±12.87 years. Before the intervention, a positive and significant correlation was observed between knowledge and dietary habit (r=0.249) (p<0.001), knowledge and attitude (r=0.249) (p<0.001), and attitude and dietary habits (r=0.264) (P<0.0001). After the intervention, the mean scores of knowledge (p<0.001), attitude (p=0.017) and dietary habits (p<0.001) significantly increased.


Education provided by WHV was effective in promoting knowledge, and attitude, and in modifying the dietary habits of women. Therefore, the use of local human resources can help improve public health.

Keywords: Education, Volunteers, Knowledge, Attitude, Dietary habits, Non-communicable diseases.

"Open access will revolutionize 21st century knowledge work and accelerate the diffusion of ideas and evidence that support just in time learning and the evolution of thinking in a number of disciplines."

Daniel Pesut
(Indiana University School of Nursing, USA)

"It is important that students and researchers from all over the world can have easy access to relevant, high-standard and timely scientific information. This is exactly what Open Access Journals provide and this is the reason why I support this endeavor."

Jacques Descotes
(Centre Antipoison-Centre de Pharmacovigilance, France)

"Publishing research articles is the key for future scientific progress. Open Access publishing is therefore of utmost importance for wider dissemination of information, and will help serving the best interest of the scientific community."

Patrice Talaga
(UCB S.A., Belgium)

"Open access journals are a novel concept in the medical literature. They offer accessible information to a wide variety of individuals, including physicians, medical students, clinical investigators, and the general public. They are an outstanding source of medical and scientific information."

Jeffrey M. Weinberg
(St. Luke's-Roosevelt Hospital Center, USA)

"Open access journals are extremely useful for graduate students, investigators and all other interested persons to read important scientific articles and subscribe scientific journals. Indeed, the research articles span a wide range of area and of high quality. This is specially a must for researchers belonging to institutions with limited library facility and funding to subscribe scientific journals."

Debomoy K. Lahiri
(Indiana University School of Medicine, USA)

"Open access journals represent a major break-through in publishing. They provide easy access to the latest research on a wide variety of issues. Relevant and timely articles are made available in a fraction of the time taken by more conventional publishers. Articles are of uniformly high quality and written by the world's leading authorities."

Robert Looney
(Naval Postgraduate School, USA)

"Open access journals have transformed the way scientific data is published and disseminated: particularly, whilst ensuring a high quality standard and transparency in the editorial process, they have increased the access to the scientific literature by those researchers that have limited library support or that are working on small budgets."

Richard Reithinger
(Westat, USA)

"Not only do open access journals greatly improve the access to high quality information for scientists in the developing world, it also provides extra exposure for our papers."

J. Ferwerda
(University of Oxford, UK)

"Open Access 'Chemistry' Journals allow the dissemination of knowledge at your finger tips without paying for the scientific content."

Sean L. Kitson
(Almac Sciences, Northern Ireland)

"In principle, all scientific journals should have open access, as should be science itself. Open access journals are very helpful for students, researchers and the general public including people from institutions which do not have library or cannot afford to subscribe scientific journals. The articles are high standard and cover a wide area."

Hubert Wolterbeek
(Delft University of Technology, The Netherlands)
