ABSTRACT
Objective: Nutrivigilance is a new concept in India. Several adverse drug reactions (ADRs) arising due to the use of Nutraceuticals are undermined and under-reported by prescribers. Spontaneous reporting of ADRs forms the backbone of Nutrivigilance. This paper will examine the knowledge, attitude, and practice of nutrivigilance among medical students and postgraduate doctors and discuss the need, challenges, and opportunities for improving nutrivigilance in the future.
Methods: A Cross-sectional study was conducted between Phase-2 MBBS (UGs) and Postgraduates (PGs) of GMC, Ananthapuramu. The study tool was a validated questionnaire having 30 questions to evaluate KAP of Nutrivigilance. Data was collected in Google forms and was analyzed using SPSS 21 and P value<0.05 was taken as statistically significant.
Results: The results revealed poor knowledge on Nutrivigilance (UGs-16% and PGs-14%). The Attitude towards Nutrivigilance was equally positive (92%, 94%) in the two groups. Practice on Nutrivigilance was 54% and 52%, respectively. There was no significant difference in KAP on Nutrivigilance between the UGs and PGs.
Conclusion: UGs and PGs lack adequate knowledge and skill of reporting ADR, but both have a positive attitude towards Nutrivigilance programme. To increase awareness on the topic, Nutrivigilance and adverse reaction reporting of nutraceuticals must be added to the academic curriculum of undergraduate and postgraduates, thus improving the reporting and monitoring of ADRs by Nutraceuticals thus improving the health of the community.

Nutrivigilance is defined as “the science and activities relating to the detection, assessment, understanding and prevention of adverse effects related to the use of a food, dietary supplement, or medical food” as per Schmitz, et al. [1]. The term “Nutraceutical” is coined from “Nutrition,” which is a health-giving, beneficial dietary constituent and “pharmaceutical”, which means medicinal remedy, in 1989 by Dr. Stephen De Felice [2]. Nutraceuticals include dietary supplements, nutrients, herbal supplements, animal-based supplements, and functional foods [3].
Most population in India are malnourished. Instead of consuming fruits and vegetables, most people tend to use nutraceuticals to avert these deficiencies and diseases. Increasing health awareness, drift in population disease demographics where younger people furthermore affected, lifestyle alterations, escalated purchasers' opulence and elevated life expectancy are responsible for increasing market for nutraceuticals in India [4]. In India, multivitamins, multi-minerals, proteins, health drinks, herbs are the common dietary supplements sold in the form of tablets, liquids, powders, capsules, soft gels to improve one’s well-being. Most of the common supplements are available without a prescription. An article published by ASSOCHAM under the title “Indian Nutraceuticals Market Study on the Current Scenario and Future trends” has shown an increased surge in usage of nutraceuticals over the past decade [5].
Lack of correct medical information or scientific support for these online-purchased products represents a major public health risk. Most of the nutraceuticals have excess quantities of nutrients than the recommended dietary allowance [4]. Though evidence suggests that few nutraceuticals enhance health in diverse ways, few adverse effects have been reported too [6]. The main problems of dietary supplements intake are represented by several adverse events (e. g.: hepatic, cardiac, renal, metabolic disorders, neurotoxicity, teratogenicity etc.)
The conception of Nutrivigilance is new in India, unlike that of Pharmacovigilance for reporting adverse events due to medicines. Tools and guidelines for signal discovery need to be developed. The Pharmacovigilance Programme of India (PvPI) receives a veritably limited number of ADRs related to the use of nutraceuticals, health, and food supplements. Currently, the Food Safety and Standards Authority of India (FSSAI) regulates the standards for health supplements and nutraceuticals. The FSSAI defined regulatory guidelines for the approval of nutraceuticals in India. Several adverse drug reactions (ADRs) arising due to the use of Nutraceuticals are undermined and under-reported by prescribers [7].
Still, there has not been much integration of nutrivigilance into standard clinical practice. There are insufficient number of studies done to assess the knowledge of nutrivigilance and usage of nutraceuticals in India. Considering that medical students are more equipped with the clinical knowledge of adverse events due to various drugs, the implications of nutrivigilance for therapeutic success are not well understood by many medical students. This study was taken up with the purpose of evaluating the Knowledge, Attitude, and Practices of Nutrivigilance among Phase-2 MBBS students and Postgraduates and remedial measures to be taken, if needed, to improve it, in order to avoid morbidity and mortality due to adverse drug reactions produced by nutraceuticals which are being consumed by more number of people nowadays.

Nutrivigilance programme should be considered as a part of the health-care system. The objective of nutrivigilance is to incorporate monitoring schemes to discern or identify the adverse effects caused by nutraceuticals for consumer safety. For nutrivigilance to succeed, and especially focused on post-market analysis, there must be a fully committed national surveillance system for nutraceuticals and consumers must have awareness of the spontaneous reporting system. The regulatory authorities, health providers and patients should observe the adverse effects of the nutraceuticals and they need to proactively report the adverse effects related to their consumption.
Despite the debate about benefits, nutraceuticals consumption is constantly growing, especially for students [8]. The evaluation of intake risks can be achieved employing some models used for drugs but adapted to dietary supplements, which include WHO scale, FDA algorithm, the Naranjo scale, Kramer scale or Liverpool scale [4]. Ide et al., have adapted the FDA algorithm to estimate a causality relationship between adverse events and dietary supplements usage [9}. Palet et al., proposed that the adverse events’ reporting system must be strongly encouraged all over the world [10]. Researchers confirmed that primary motivation for consuming such nutraceuticals include maintaining good health, increasing energy, muscle strength and enhancing physical performance [6]. It was reported that higher education levels were associated with higher dietary supplements usage [11].
In a study done by Eric A. Klein et al., it has been found that, there is a risk of development of prostate cancer in males on long-term consumption of vitamin E [12]. Similarly, in another study done by Shreena S Patel et al., Green tea extract caused hepatotoxicity in a 16-year-old male [13]. In a study done in Saudi by Mashael Abdullah Alowais et al., many of health sciences students do not have accurate information about dietary supplements [14]. In a study done by S Afina et al., students had low objective knowledge of functional foods, but had a positive attitude towards it [15]. Another study done by Singh S et al., to assess the KAP on nutraceuticals among nursing students and medical students showed that medical students have increased knowledge and positive attitude towards nutraceuticals usage [16].
This study presents some aspects that encourage the development of nutrivigilance as a main activity in the dietary supplements field. Spontaneous reporting forms the key of Nutrivigilance programme. The current study suggests that both undergraduate medical students (16%) and postgraduate students (14%) lack sufficient knowledge and have a positive attitude (92%, 94%) towards the role of nutraceuticals in human health and the Nutrivigilance programme. This result does not correlate with previous studies done on KAP of dietary supplements and nutraceuticals in the general population. But, there are no studies to assess the KAP of Nutrivigilance in India.
This study showed that there is no statistically significant difference between the two groups’ knowledge, attitudes, or practices; nonetheless, the groups’ perceptions of nutrivigilance attitudes are more favorable than their awareness and application.
This study concludes that phase-2 undergraduates and PGs lack adequate knowledge and skill of reporting ADR from Nutraceuticals, but both have a positive attitude towards Nutrivigilance programme. There is a wide variationin between the knowledge and attitude aspect of both the groups.
Awareness among the healthcare fraternity is to be created to minimize the use of nutraceuticals and to be used whenever essential. The need, scope, and importance of Nutrivigilance is to improve the process of adverse events reporting in the country due to the recent surge in the growth of nutraceuticals. More strict vigilant measures need to be implemented to raise concerns regarding nutraceuticals. Reducing the over-the-counter availability of nutraceuticals will reduce the excess unwanted intake by student communities who hope for the miracle of improving their health and physical fitness by alternate means. More number of community outreach programmes, Continuing Medical Education (CME) on Nutrivigilance can be conducted among UG and PG students during their study period. More of orientation programmes, foundation courses to medical, nursing and practicing doctors can be given to enrich their knowledge and increase the practice. It is important to strengthen the health science curriculum concerning this topic and access to scientific and unbiased information with the aim of producing better-informed future health professionals.
It is recommended to carry on more studies across India to correlate with the findings and to assess the knowledge aspect among students of various geographical zones within the country.
