Comparative Analysis of Dietary Habits and Nutritional Profiles: Sidi Ali Ben Aoun vs. Grand Tunis

Abstract

INTRODUCTION: Tunisia is affected by the nutritional and dietary transition. AIM: To compare dietary habits and nutritional profiles between a rural agricultural area Sidi Ali Ben Aoun and an urban area Grand Tunis. METHODS: This is a comparative cross-sectional study conducted on a sample of 220 participants, including 110 from Ben Aoun and 110 from Grand Tunis. Data were collected based on a pre-established questionnaire about dietary lifestyle and habits survey. Validated scores were used: Alimentary Diversity of Households (SDAM), the Food Consumption Assessment score (SCAM), MEDI-LITE and IPAQ. RESULTS: The mean age was 37.2±15.3 years for the urban population versus 38.7±13.8 years for the rural population (p=0.43). In the rural population, males were 54.5% vs 48.2%; p=0.34. The occurrence of non-communicable diseases was lower in Ben Aoun (p<0.001). The adopted diet in the region of Ben Aoun aligned with the principles of the Mediterranean diet (MEDI-LITE score was 13.2±1.76 versus 7.35±2.65 in Grand Tunis, p<0.001). Both studied regions had a similar level of food security as assessed by the SDAM (p=0.006). However, household dietary diversity was more present in the rural region: the average SCAM was 11.4±0.79 in the rural group compared to 10±1.31 in the urban group (p<0.001). CONCLUSION: The rural region (Sidi Ali Ben Aoun) was characterized by a healthier and more diverse diet compared to the urban region (Grand Tunis).
