Exploring health advice by dental professionals in USA: A secondary data analysis of NHANES (2015-2018)

Objectives: To examine socioeconomic and ethnic variations in the provision of health advice by dental professionals.Methods: Data were from the National Health and Examination Survey (NHANES) (2015-2018). Socioeconomic position (Poverty-income ratio and education) and ethnicity were the main exposures. The outcome variable of interest was whether participants received health advice regarding the "benefits of quitting cigarettes," "benefits of monitoring blood sugar levels," and "importance of oral cancer screening". Logistic regression analysis was used to examine the relationship between socioeconomic factors/ethnicity, and health advice after adjusting for covariates.Results: The analysis included a total of 5524 people aged eighteen and above who had complete data. Black and Hispanic individuals had higher odds of receiving advice on smoking (OR = 1.49, 95% CI: 1.04-2.12 and OR = 1.48, 95% CI: 1.05-2.07, respectively) and glucose monitoring (OR = 3.00, 95% CI: 2.03-4.43 and OR = 3.14, 95% CI: 2.04-4.82, respectively), but no significant difference for cancer screening advice.Higher poverty-income ratios (PIR) were associated with lower odds of receiving smoking advice (OR = 0.91, 95% CI: 0.84-0.98), but no significant associations were observed for glucose monitoring or cancer screening advice. The study's findings reveal a social gradient in the provision of cancer advice, with individuals having higher education levels, particularly university education (OR = 1.69, 95% CI: 1.24-2.31), showing significantly higher odds of receiving cancer screening adviceConclusion: The study highlights significant variations in health advice provision in dental settings, with education level, ethnicity, and smoking status playing prominent roles, emphasizing the need for targeted interventions to promote equity and cultural competence in delivering health advice in dental settings.Practice implication: The results emphasize the importance of strong policies and ongoing education for dental professionals to ensure optimal treatment and prevention.
