RESUMEN
BACKGROUND: Dietitians are healthcare professionals with potential roles and impacts in primary care (PC) settings when applying knowledge and expertise to educate healthcare clients at all levels and treat chronic diseases. This study seeks to compare and evaluate the nutrition care services and practices in obesity management in primary care centres for two periods (2016 and 2019) in Jeddah city, Saudi Arabia. METHODS: Surveys with service self-reporting evaluation used responses from 18 and 27 centres in 2016 and 2019. Services evaluation used no reference to a standard, but 18 of the surveyed PC centres in 2019 were previously visited in 2016 to assess the provided nutrition care services for adult obesity in PC centres. The re-visit survey investigated improvements in services achieved in 2019 concerning services for adults with obesity. A chi-square test was used to compare the surveys' results in the two periods, which resulted in a significant difference in the provided nutrition care services for adult obesity between 2016 and 2019. RESULTS: Dietitians' employment has significantly changed (P < .0001) in 2019 compared to 2016. Dietitians were significantly noticed as the primary source of nutrition information after their integration into the services (P < .0001) in 2019. Services provided for adult obesity increased significantly (P value < .0001) in the second phase. However, there was no significant difference in serving adult groups between the two periods (P = .056). CONCLUSIONS: Integrating dietitians into the PC services significantly enhanced their role in supporting PC services for conditions relating to adult obesity, which allowed them to be the most important source of the delivered nutrition information to patients. The employment rate of PC dietitians accredited by the governing body is significantly increasing; the Saudi Commission for Health Specialties will need to monitor it to ensure that dietitians have the qualifications and skills to provide professional medical nutrition therapy to patients. Further research to evaluate the quality of PC dietetic practice and improvements in patient outcomes is required to strengthen the importance of integrating registered dietitians into the services.
