Abstract
Background: Time trends in nutrient intakes have been reported from household food
consumption using food table values. However, accurate estimates of trends over the past decade in
nutrient intakes using computerised nutrient analysis of Indian diets are lacking.
Objectives: To examine changes in nutrient intakes of Indian adults by re-analysis of dietary food
intakes between 1998 and 2015 with computerized diet analysis software, CDiet.
Methods: Diets of men and women (20-60 years) from Western India in 1998-2000 (n=559), in
2007-2009 (n=638), and in 2013-2015 (n=1073) were assessed mostly using semi-quantitative
food frequency questionnaire by interview method. Daily nutrient intakes were calculated with laboratory-
based food composition database using computerised diet analysis software (CDiet). Physical
activity was assessed through a structured questionnaire and classified as; sedentary, light, and
moderate activity level (PAL). Trends in mean nutrient intakes were evaluated using generalised
linear regression model.
Results: Over the past 17 years, trend estimates of energy intakes adjusted for age and PAL
showed a decline of 11 to 19.7% for men, whereas an insignificant increase of 1 to 3% in women.
Higher reduction (23 to 45%) was seen in intakes of iron, riboflavin, thiamine, and folate than in
other micronutrients. Men with sedentary activity increased by 16.8%, whereas women having
light/moderate activity increased by 7.2%.
Conclusions: A decreasing trend in nutrient intakes over the last 17 years and an increase in sedentary
behavior suggested the need for change in lifestyle and increased consumption of nutrient--
dense foods by Indian adults.
