Background: This study explored the relationship between socio-economic characteristics at the individual and neighbourhood levels, and wellbeing and lifestyle behaviours of young Iranian women.Methods: Cluster convenience sampling was used to select 391 Iranian women participated in this cross-sectional survey in Shiraz, Iran in 2013. A scale adapted from the British General Household Social Capital questionnaire was used to assess neighbourhood socio-economic characteristics. The satisfaction with life scale, WHO quality of life scale, and the International Health and Behaviours Survey were used to measure wellbeing outcomes and lifestyle behaviours.Results: Findings showed participants were dissatisfied with their neighbourhood socio-economic conditions (M: 36.3±9.8, score range: 11-60) as well as the availability of leisure facilities (M: 1.8, score range: 1-5) in their local areas. Correlations and regression analysis revealed that better neighbourhood socio-economic characteristics were positively associated with better wellbeing outcomes as well as healthier lifestyle behaviours.Conclusion: These findings suggest the need for transitioning economies to be cognisant of the importance of social policy and strategies for enhancing neighbourhood socioeconomic status in order to enhance wellbeing outcomes for sub-populations, including young women.
