Study Objective
To assess HCPs’ knowledge, attitudes, practices, and loyalty (behavioural intention) regarding nutrition and supplementation, and to identify gaps and barriers to effective implementation in clinical care.
Short Abstract
Background: Poor diet is a major global health risk, yet nutrition education for healthcare professionals (HCPs) remains limited, leading to variable confidence and competence in providing nutrition and dietary supplement advice.
Objective: To assess HCPs’ knowledge, attitudes, practices, and loyalty (behavioural intention) regarding nutrition and supplementation, and to identify gaps and barriers to effective implementation in clinical care.
Methods: A 67-item electronic KAPL survey was distributed to HCPs via professional networks and social media. Eligible respondents included physicians, nutritionists, dietitians, allied health practitioners, mental health professionals, and researchers with clinical experience. Outcomes across professional groups were analysed with t-tests and ANOVA (p<0.05).
Results: 52 HCPs completed the survey (Nutritionists/Dietitians = 40.4%; Physicians = 19.2%; Other = 40.4%). Mean knowledge scores were highest among Nutritionists/Dietitians (70.7%, SD = 15.2) and lowest among Other (47.8%, SD = 21.3). Attitudes toward nutrition were positive (M = 4.19/5, SD = 0.43), but practice scores varied, with Nutritionists/Dietitians (M = 4.20, SD = 0.70) higher than Physicians (M = 3.66, SD = 0.57) or Other professionals (M = 3.59, SD = 0.65). Key knowledge gaps were in biochemical thresholds for micronutrient deficiencies. Barriers included conflicting guidelines, time constraints, and affordability concerns.
Conclusion: While HCPs recognise the importance of nutrition and supplementation, significant knowledge gaps—particularly on diagnostic thresholds—limit effective practice. Tailored, concise, evidence-based resources may help bridge these gaps and support consistent, confident nutrition counselling.
