Data presented as odds ratio (95% confidence interval) of asthma. All models adjusted for age, race, sex (for all), annual household income, serum cotinine, and serum C-reactive protein.

z score for children only (body mass index, waist circumference, percent body fat).

^{^†}

P < 0.01.

^{^‡}

P < 0.05. Bold typeface used to highlight P < 0.05.

^{^§}

Compared with normal weight.

^{^||}

Compared with noncentral obese.

^{^¶}

z score for children and adults, calculated separately for each age group (waist-to-height ratio, trunk-to-total fat mass ratio, legs-to-total fat mass ratio, trunk-to-legs fat mass ratio).
