Quantitative estimates of dietary intake with special emphasis on snacking pattern and nutritional status of free living adults in urban slums of Delhi: impact of nutrition transition

Table 4 Median intake with adequacy of nutrients (expressed as per consumption unit^a) and percentage distribution of Nutrient Adequacy Ratio in study households (N = 261)

Nutrient	Recommended Dietary Allowances^b (2010)	Median Intake	Adequacy (% RDA^c)	Nutrient Adequacy ratio (% of Households)
				Inadequate		Fairly adequate		Adequate
				(<0.66)		(0.66- <1.00)		(≥1.00)

^aConsumption Units (CU): One consumption unit is defined as the calorie consumption of an average adult man, weighing 60 kg, doing sedentary type of work. The other coefficients are worked out on the basis of calorie requirement proportionately. Indian Council of Medical Research (ICMR) developed these coefficients for different age groups, sex and physical activity
^bIndian Council of Medical Research: A report of the expert group of Indian Council of Medical Research; Nutrient Requirements and Recommended Dietary Allowances for Indians, 2010
^c RDA: Recommended Dietary Allowances
^dPercentage calculations after correction were obtained from a normal distribution with mean and variance derived from the overall means and estimated between- household variability, from repeated measures random intercepts model
^eFor protein, vitamin C and thiamine, probabilities were based on calculations with transformed data and details are provided in Additional file 4: Table S4
^fValues in bold show the inadequacy (<0.66 Nutrient Adequacy Ratio) in more than 50 % of the households
