Childhood obesity and weight loss predict the persistence and remission of childhood sleep-disordered breathing
| Persistent vs. no SDB | Remitted vs. no SDB | Remitted vs. persistent SDB | |

| Baseline weight | 2.09 (1.51–2.89)< .001* | 1.66 (1.07–2.58).023* | 0.80 (0.51–1.25).324 |

Data are odds ratios (95% confidence interval) and P values from a multivariable, multinomial logistic regression model adjusted for sex, race and age (forced entry) with stepwise (backward elimination) of childhood height, weight, BMI%, hips, waist and neck as well as change in height, change in weight, change in BMI%, change in hips, change in waist and change in neck. Odds ratios for each predicting variable represent an increase in one standard deviation (e.g. change in 13 kg from baseline to follow-up). No SDB (n = 248) served as the common reference group, while persistent SDB (n = 95) served as the reference group for remitted SDB (n = 45).
Data are odds ratios (95% confidence interval) and P values from multivariable, multinomial logistic regression models for baseline BMI% groups and change in BMI% adjusted for sex, race and age (all forced entry). Odds ratios for change in BMI% represent an increase in one standard deviation (e.g. increase in 13 kg from baseline to follow-up). Odds ratios for change in BMI% represent an increase in one standard deviation (i.e. increase in 23 percentiles of BMI from baseline to follow-up). No SDB (n = 248) served as the common reference group, while persistent SDB (n = 95) served as the reference group for remitted SDB (n = 45). BMI% = body mass index percentile for age and sex. Childhood overweight = BMI percentile between 85 and 94. Childhood obesity = BMI percentile ≥95.
Statistically significant at P ≤ .05.
