TABLE 2.

Association of DNA methylation (DNAm) change with asthma acquisition from pre- to post-adolescence at 13 cytosine-phosphate-guanine (CpG) sites that are sex-specific. Significant interactions between DNAm and sex on asthma acquisition from 10 to 18 y identified in the Isle of Wight birth cohort (IOWBC)a were further tested in the Avon Longitudinal Study of Parents and Children 11(ALSPAC) cohortb. Males are in the reference group

a

For the analyses in IoW, logistic regression models were adjusted for birth weight, sex, maternal and paternal disease status of asthma, socio-economic status (SES), change of atopic status, BMI, height from 10 to 18 y.

b

Analyses of ALSPAC used similar covariates: maternal disease status of asthma, sex, birth weight, SES, atopy status at 7 y, and changes of height, and BMI from 7 to 15/17 y.

c

Est., Estimated main effect; Int., interaction coefficient of the CpGs with the sex of a child. Interaction effects consistent between the two cohorts are with bold fonts; CI, confidence interval.

d

PRaw, raw P-value; PFDR, adjusted P-value for multiple testing by controlling a false discovery rate (FDR) of .05. All the P-values are for interaction effects.

e

Chr., Chromosome.

f

Genes closest to the CpG site annotated using the UCSC genome browser.
