Introduction
Nutrition education interventions reduce morbidity and mortality, costs of care and play an important role in maintaining health and quality of life.The survey was conducted to assess Italian nutrition professionals' involvement in nutrition education programs.
Evidences show that nutrition interventions reduce morbidity and mortality, costs of medical care and play an important role in maintaining health and quality of life [1].A healthful diet promotes optimal health, growth and cognitive development in children and adolescents, contributes to the prevention of chronic diseases in adults and prevents or delays the spiral towards illness and disability in elderly [2,3].Therefore primary prevention of chronic diseases can be accomplished by addressing a handful of modifiable behaviours, promoting health throughout the life cycle [4].

Keywords: Nutrition education; Nutrition prevention; Nutrition professionals
A questionnaire was developed and mailed to 1504 members of the two main Nutrition Italian Societies and subjects registered in our University Nutrition Courses archives.Data from 1053 respondents were analysed.Three quarters of the respondents are females; 50% of the whole sample lives and works in Northern Italy, while 26% and 24% are employed in Central and Southern Italy respectively; 43% are Medical Doctors with a post graduate degree in Human Nutrition and Dietetics, 33% are Nutritionists with a Biology degree and 24% are Dietitians.At present 56% of the whole sample is self-employed in private ambulatory care centres, 32% and 12% serve on nutrition support teams either in hospitals or in public nutrition services.Ninety per cent spends time on nutrition education programs mainly addressed to the children and adolescents (38%), to the adults (33%), to the elderly (16%) and to the pregnant women (11%) and 2% to all the groups over reported.The whole sample equally served in public sanitary services (34%), scholastic institutions (28%) or private structures (38%).Most of the professionals are involved in nutrition education programs, nevertheless analysing our results we may assume that most professionals are not really involved in nutrition education programs but only in nutritional counselling.
Recent studies have shown that sustainable changes may be achieved by nutrition education interventions focused on specific target groups through life span [2].Dietary recommendations for a healthful diet across Europe recommend consumption of at least five portions of fruit and vegetables a day, reduced intakes of saturated fat and salt, and increased consumption of complex carbohydrates and fibre [2,5].However, dietary consumption surveys show that most Europeans do not meet these guidelines [6,7].The alarming and increasing prevalence of overweight and obesity indicates that health promotion through dietary habits and lifestyle modifications remains a key point [6,8].There is a need to develop and implement effective programs and policies that will result in adopting healthier diets in all ages, identifying the risk behaviours in order to target and tailor specific nutrition interventions, which should be part of nutritional surveillance projects and should also be carried out in hospitals as well as in ambulatory care clinics [9].Nutritional professionals should take care of these interventions since most health professionals, in particular physicians, recognize that they lack the education and training in medical nutrition needed to counsel their patients and to ensure continuity of nutrition care [1,[10][11][12][13][14]. Indeed in a previous review published in 2010 [15] aimed at describing the state of health nutrition practice in Italy, exploring the nature, role, and utility of training for nutrition professionals, emerged the need for increasing nutrition education interventions, which should therefore involve active participation and collaboration of nutrition professionals at different levels according to their University degree: Physician Nutrition Specialists (PNS), Nutritionists with a Biology degree (NB) and Dietitians (D).
The aim of the present study was to investigate the Italian nutrition professionals' involvement in promoting health using nutrition education programs both in primary and secondary prevention in the different main areas of interest, in target population, by means of a cross sectional survey.Indeed nutrition education interventions may be delivered both to health groups with risk factors and/or familiarity predisposition to chronic degenerative pathologies aiming at preventing the disease, as well as to groups who had already developed chronic degenerative disorders aiming at controlling and counteracting the evolution of the disease.
The final version consisted of two sections.Section A included 8 items related to demographic data and actual professional employment.Section B included 18 items aimed at obtaining information on nutrition programs delivered by the professionals, target population, kind of nutrition intervention, methodology and results indicators used by the same professionals after their nutrition interventions.
A questionnaire was developed specifically for this study by a team of university nutrition professionals.Four dietitians working at Pavia's University were then asked to revise the instrument and to review the questions for clarity and relevance.Their suggestions were used to develop the questionnaire final version.The questionnaire was previously piloted on a sample of 52 nutrition professionals in order to further verify its comprehension, easiness and quickness to fill in, and revised accordingly, but validity and reliability were not formally tested.

Materials and Methods
The questionnaire was developed and e-mailed to 1504 nutrition professionals recruited from the members of two scientific nutrition societies (ADI, Italian Dietology Association and ANSISA, Italian Association of Specialists in Dietetics and Nutrition) and from the University archives among former students registered in University courses of Dietetics and Human Nutrition, in Post Doc course of Human Nutrition and Master courses.Data from all the respondents were treated anonymously.All participants had been informed of the study goals, and each participant provided written informed consent.The study was conducted in accordance with the World Medical Associations Helsinki Declaration for Human Studies and approved by the Ethics Committee of University of Pavia.
Responses form the completed questionnaires were considered and all statistical analyses were performed using SPSS statistical software package for Windows Version 18.0 (SPSS Inc., Chicago, IL, USA, 2010).Descriptive statistics as frequency distribution were calculated.Subjects' age was expressed as mean ± standard deviation.Pearson's correlation coefficient was used to investigate the relationship between professionals' age and time involvement in nutrition intervention programs.The statistical significance level was set to p<0.05.

Results
One thousand and fifty three professionals responded to the questionnaire (70%).Three quarters of the respondents are females; mean age of the total sample was 45 ± 12 years (range 22-75 years; C.I. 95% 44.28-45.72).
Forty three per cent of them are Physician Nutrition Specialists (PNS), mainly Medical Doctors (MD) with a post graduate degree in Human Nutrition and Dietetics, 33% are Nutritionists with a Biology degree and 24% are Dietitians.
Fifty per cent of the whole sample lives and works in the northern part of Italy, while 26% and 24% are employed in the central and southern part of Italy respectively.
Sample demographic characteristics as far as age, gender, residency, university degree status, employment setting and years of involvement in nutrition practice are reported in Table 1 This study was conducted to assess Italian nutritionists' involvement in nutrition education programs since lifestyle modifications in dietary habits are reached through long term target specific education interventions both in primary and secondary prevention.
The percentage of the respondents to this survey is high (70%) and therefore useful to draw a picture of the nutrition education involvement of the different professionals.

Discussion
Three quarters of the respondents are females in line with the increasing prevalence of female students in sanitary graduate courses, observed for the last decades in Italy.The age range is wide including just graduates as well as close to retirement professionals.Most of them are Medical Doctors (MD) since the two Associations include mostly MD among their associate members.More than 50% of the sample involved in nutrition education programs is self-employed in private ambulatory care centres suggesting that most professionals have greater opportunities in organizing and managing educational programs on individual as well as group basis.In acute care settings, best nutrition practices have been shown to improve patient outcomes and reduce health care costs [16].Nevertheless a previous study [15], describing the state of health nutrition practice in Italy, suggested that the public health nutrition workforce and infrastructures lack the necessary capacity to respond to national population needs regarding food and nutrition at many levels.Besides it outlined the need for improved nutrition education interventions promoting health and dietary changes.
As would be expected most professionals deal with counselling and nutrition education programs for all age target groups at different levels, both in primary and secondary prevention.Besides the negative correlation between years of involvement in nutrition practice and participation in nutrition intervention programs suggests that the youngest professionals are most likely to devote themselves to education intervention programs.As supposed, primary prevention interventions are more prevalent given that there is a lack of professionals who could devote to these programs in secondary nutritional education approaches in public and private hospitals.
Metabolic disorders and cardiovascular diseases are the main areas of interventions, reflecting the high prevalence rate of these conditions in industrialized countries [17,18].Analysing the intervention methods, frequency of interventions, materials used and the lack of long term results indicators, we may assume that mostly professionals are not really involved in nutrition education programs but only in nutritional counselling.
Back in 1997 the FAO Expert Consultation regarding Nutrition education for the public [19] underlined that nutrition education is based on the sound application of knowledge derived from the food and nutrition sciences about the relationships between diet and health [20].
The use of educators with training in nutrition, comprehending both food and Nutritional science, allows efficient use of human resources, competent to provide appropriate educational messages.Nutrition education is effective only when the path grows through knowledge to the know-how, reaching awareness.
Overall, the professionals reported no significant intervention outcomes, and this limit has already been outlined by other authors [3,[21][22][23][24].Our results showed that very few interventions have reached a behavioural change (9%) that should be, indeed, the final aim of any education program.Among those who reported positive outcomes increased nutrition knowledge seems the more frequently achieved (27%).Since providing nutrition education to motivated persons is generally more successful [27], additional efforts should be done on each person's perception of his/her chance of developing a condition, and of how serious the condition and its consequences would be, as motivating factors for behaviour changes [3].Good nutrition and appropriate lifestyle habits must start early in life to achieve a healthy condition through life span.

Conclusions
This study presents few limits that must be acknowledged.More detailed questions could have been included in the questionnaire to provide further information on performance indicators, with a consequent disadvantage in time spent for its compilation.Besides we have not been able to reach all the nutrition professionals in Italy.Despite this limit the study shows some strength.Indeed this is the first study in Italy investigating nutritional education interventions undertaken by nutrition professionals.
Nutrition professionals should be trained on designing specific interventions, aimed at changing effectively nutrition behaviour at long term.The ultimate goal of nutrition education programs is to transfer acquired knowledge to groups so individuals can make conscious choices about their diet and lifestyle to achieve and maintain good health.
The results of this study outlined the need to focus on research methodology training for Nutritionists and Dietitians in health care aimed at achieving sustainable changes and studying the consequences of these changes at long term.
Raising awareness of the role of nutrition in chronic degenerative diseases prevention and management could contribute to target well-constructed intervention programs, develop and evaluate the impact of these programs as already pointed out by other authors.Only applying a strict methodology we may verify the long lasting changes of nutrition education programs on dietary behaviour, biochemical variables and health through life span.
