	Absolute Disparity			Relative Disparity
Healthy People 2010 LHI (Age Range)	Absolute Disparity 2003^a	Absolute Disparity 2007^a	Change in Absolute Disparity 2007–2003^b	Relative Disparity 2003^c	Relative Disparity 2007^c	Change in Relative Disparity 2007–2003^d
Vigorous physical activity ≥ 3 d/wk for 20 min (14−17 y)	−9.8	−7.1	−2.7	−14.4	−10.0	−4.4
Obese; BMI at or above the gender- and age-specific 95th percentile (10−17 y)	4.3	4.1	−0.2	31.3	26.7	−4.6
Usually/always unhappy, sad, or depressed during the past mo (6−17 y)	4.1	3.5	−0.6	350.2	346.3	−3.8

Personal doctor or nurse (0−17 y)	8.0	3.2	-4.9*	9.8	3.4	-6.4*

Note. BMI = body mass index; ED = emergency department; LHI = leading health indicators.

^{^a}

Percentage point difference between children with and without special health care needs.

^{^b}

Change in percentage point difference between children with and without special health care needs between 2003 and 2007. Negative values indicate a reduction in absolute disparity; positive values indicate an increase in absolute disparity.

^{^c}

Percent difference between children with and without special health care needs.

^{^d}

Change in percent difference between children with and without special health care needs between 2003 and 2007 (measured in percentage points). Negative values indicate a reduction in relative disparity; positive values indicate an increase in relative disparity.

*P < .05; Z-statistic > 1.96.
