Beskrivende tekst

The child BMI variable was calculated from children's height and weight variables (if in US converted to metric) using the following equation: BMI=(mass (kg))/(height (m)^2). The calculated BMI and percentile growth charts from the CDC were used to categorize children as Normal (<85th percentile), overweight (>=85th and <95th percentile) and obese (>=95th percentile). Each child's age (used mid-year e.g., 30.5 months for a 2 year old) and gender were used to determine which percentile cut-offs to compare. The universe for this variable includes all children age 0 to 17.
