Exploring cultural, social, and biological factors influencing obesity onset in two racial-ethnic groups in Quibdó, Colombia

Abstract

Obesity rates in Colombia are increasing, with variations among racial and ethnic groups. Studies on adult obesity often address socio-economic status, gender, and education but neglect racial-ethnic influences, notably in areas like Quibdó. Therefore, based on the theory of triadic influence, we conducted a qualitative study to identify biobehavioural, social, and cultural phenomena that, from the perspectives of the participants, influence the onset of obesity in Afro-Colombian and indigenous in Quibdó in 2022. The stratification variables were race, ethnicity (Afro-Colombian and Indigenous), and educational level (secondary or higher). Based on a literature review of qualitative studies that commonly explored food culture, nutritional status, and physical activity in analysing obesity within racial and ethnic populations, we incorporated these categories into our research methodology through semi-structured interviews. A framework analysis was used as a qualitative methodology to organise and analyse the collected data. We conducted 21 semi-structured interviews, 13 with the Afro-Colombian population and eight with indigenous inhabitants. The results indicate that cultural beliefs, forced displacement/migration, and alterations in public order have resulted in changes in food security, food culture, and physical activity practices, affecting the onset of obesity. Notably, distinctions in cultural beliefs regarding food culture and health as factors influencing obesity were observed between Afro-Colombians and the Indigenous populations; however, educational differences within the same racial ethnic group were not predominant. Findings indicate obesity is influenced by cultural, social, and biobehavioural factors, especially in regions with racial-ethnic communities facing complex conditions, necessitating targeted racial-ethnic public health policies.
