Abstract

Healthy dietary behaviors are among the key components of preventing noncommunicable diseases and promoting public health. However, evidence from a cross-sectional study showed that individuals’ readiness to change behavior is not uniform and is influenced by personal and contextual characteristics. Accordingly, designing identical and generalized interventions for all individuals cannot address differences in readiness for change. This policy brief emphasizes the need to adopt stage-based, targeted, and tailored interventions appropriate to each individual’s condition. The findings indicate that variables such as age, sex, education, employment status, marital status, tobacco use, sleep duration, and anthropometric indicators including BMI and waist circumference are associated with stages of change in dietary behaviors, and this can serve as a basis for identifying groups in need of intervention. In such a context, the health system should adopt personalized interventions and incorporate readiness to change assessment into primary care. Implementing this approach requires staff training; simultaneous intervention on high-risk behaviors such as diet, sleep, and tobacco use; systematic recording of assessment results in health records; and a focus on high-risk groups, including individuals with higher BMI, smokers, and those with insufficient sleep. Overall, this policy brief suggests that health policymakers should prioritize stage-based educational interventions and the use of screening data to create conditions for improving healthy dietary behaviors among middle-aged adults. © 2026, Isfahan University of Medical Sciences(IUMS).
