Dairy Product Consumption among Adults and Determining the Population-Attributable Risk of Common Non-Communicable Diseases: A Population-Based Cross-Sectional Study

Background: Over the past decade, Iranian households have experienced a decline in dairy product consumption. This study aimed to evaluate the population-attributable risk of prevalent non-communicable diseases related to dairy product consumption. Methods: This cross-sectional analytical study involved 628 adults over 18 years old in Hamadan City in 2021. Clusters were selected based on comprehensive urban health centers. The standardized Iranian version of the food frequency questionnaire was used. Participants were categorized into 3 levels of dairy product consumption: 1 serving per day, 1–2 servings per day, and ≥3 servings per day. Results: The mean age of the 628 participants was 38.05 (SD: 12.5), with 42.36% being male. Cheese (54.5%), yogurt (39.7%), and milk (30.4%) were consumed most frequently. The prevalence of insufficient dairy product consumption was 48.6%, higher than that reported in previous studies. Insufficient dairy product consumption was associated with hypertension (9.3%), cardiovascular disease (5.6%), and osteoporosis (5.1%). Conclusion: Individuals with lower education levels, female gender, lowest quartile of socioeconomic status, and those diagnosed with cardiovascular disease were more likely to have insufficient dairy product consumption. Insufficient dairy product consumption was associated with hypertension, cardiovascular disease, and osteoporosis.
