• Nutrition and health are two important and closely related determinants of human development and productivity.
  • Prevalence of India is passing through a developmental, demographic, nutritional and epidemiological transition with traditional habits being replaced by unhealthy dietary practices leading to diet related chronic diseases such as diabetes, hypertension, coronary artery disease and cancer.
  • The focus of nutrition and health care must be directed towards disease prevention and health promotion. For disease prevention, public health issues, life styles e.g. dietary practices and patterns and personal habits are known to play pivotal role in the maintenance of body weight.
  • The international journal of diabetes in developing countries says that there is alarming rise in prevalence of diabetes which has gone beyond epidemic form to pandemic form.
  • Globally diabetes affects 246 million people which are about 6 per cent of the total adult population.

Prospect rational

  • Dietary guidelines should not be only nutrient centered but should take into account the traditional and cultural background, together with socio-economic, and environmental issues to help consumers to make healthy and informed choices.

Development of a Nutritional informatics platform

The study proposed will provide the information that will be necessary for determining appropriate nutritional status, surveillance and programs. Further the study will contribute to the development of a database that is required to gather the nutritional status of the population and their dietary practices, which will give adequate information to suggest suitable modifications (as recommended by the National Institute of Nutrition).


An internet or telephone based Personalized Human Centered Dietary Decision Support System for diabetic populations will be designed and developed and can be accessed remotely through computers or cell phones (depending on the technology platform) available to the users. The system has the following components

  • Electronically monitoring of diet record.
  • Ability to upload image of the food consumed
  • Personalized dietary feedback
  • Alerts/reminders

Broad Objective:Design and Evaluation of a Personalized Human Centered Dietary Decision Support System among diabetics.

Specific Objective:(1) Examine and compare the factors that influence the intake of healthy diet among diabetics living in urban versus rural settings of Himachal Pradesh (2) Identify the necessary components of the Personalized Human Centered Dietary Decision Support System that can gather, analyze and provide individualized dietary feedback. (3) Compare the effectiveness of the Personalized Human Centered Dietary Decision Support System to other paper based methods of diet record for documenting nutrient intake among diabetics.

Study Area

Existing Gaps

  • The lack of success with adoption and adherence to dietary recommendations for disease prevention indicates a need for additional research about eating behavior and motivation.
  • There is a need to have a multimedia communication package aimed at various diverse stakeholders.
  • Nutrition education is an important component; it is the weakest link in all the Nutritional Intervention Program.
  • The functionaries do not have proper audiovisual aids to communicate uniform messages to the communities (ICMR, 2006).
  • A communication strategy needs to be designed and implemented for disseminating nutrition information.
