Introduction: The rising read in the prevalence of, non-communicable diseases makes assessment of its risk factors essential. Considering the importance of interventions targeting lifestyle modification for prevention of these diseases, the current study aimed to evaluate perceptions and experiences of Tehranian women regarding healthy nutrition. Materials and Methods: This is a qualitative study, conducted using the grounded theory approach. In total 8 semi-structured focus group discussions were conducted at the Tehran Lipid and Glucose Study (TLGS) unit, between 2008 and 2009. Participants were 102 women, aged 25-65 years, selected and recruited from the TLGS cohort. All interviews and focus group discussions were audio recorded and transcribed verbatim. Qualitative content analysis of the data was conducted manually according to the Strauss and Corbin analysis method and differences in in coding were resolved via discussions by at least three researchers. The conformability and credibility of the data were established. Results: Using content analysis, “inefficient education”,” lack of access”, and “individual tastes and preferences” were identified as the barriers to healthy nutrition. Conclusion: Study results demonstrated the three main personal and environmental barriers for healthy nutrition as perceived by women. Understanding these barriers might facilitate the designing of effective preventive strategies, and implementation appropriate of interventions among Tehranians.
