This study aimed to sociologically investigate the interaction between lifestyle, income, and religiosity among individuals over 14 years old in Kohgiluyeh and Boyer-Ahmad Province. The theoretical framework was developed by integrating Max Weber’s perspectives (the role of religious values in economic behaviors), Émile Durkheim’s (religion and social cohesion), and Pierre Bourdieu’s (habitus and cultural capital). The research adopted a quantitative, descriptive-correlational, and cross-sectional design. Data were collected from 385 individuals out of a population of 470,617 using multistage cluster sampling and standardized questionnaires on lifestyle (LSQ), religiosity (Glock & Stark), and income. Analyses conducted with SPSS software revealed a significant positive correlation between religiosity and lifestyle (r=0.58, p<0.01), particularly in the spiritual self-actualization dimension (r=0.67, p<0.01). Income had a direct effect on lifestyle (β=0.184, p<0.001) but showed no significant relationship with religiosity (β=0.083, p>0.05). Hierarchical regression analysis indicated that income, as a moderating variable, strengthens the effect of religiosity on lifestyle in lower-income groups (β=-0.214, p<0.01). Path analysis confirmed religiosity as the strongest predictor of lifestyle (β=0.512, p<0.001). The findings underscore the need for policies to reduce income disparities and promote healthy lifestyles through religious values, providing a foundation for future research.
