Objective
Equivocal findings have been reported between maternal depression and
children’s growth possibly given limited attention to its disproportionate
impact by child sex. We assessed the relationship between the timing of maternal
depression and children’s growth in a population-based prospective birth cohort
with particular attention to sex differences.
Methods
The Upstate KIDS Study comprised 4,394 children followed through 3 years of age
from 2008 to 2010. Maternal depression was measured antenatally by linkage with hospital
discharge records before delivery, and postnatally, by depressive symptoms reported from
questionnaires. Child’s growth was measured by sex-and-age-specific weight,
height, weight-for-height, and body mass index. Adjusted linear mixed effects models
were used to estimate growth outcomes for the full sample and separately by plurality
and sex.
Results
Antenatal depression was associated with lower weight-for-age (−0.24
z-score units; 95%CI: −0.43, −0.05) and height-for-age
(−0.26; −0.51, −0.02) among singleton boys. Postnatal depressive
symptoms were associated with higher weight-for-height (0.21; 0.01, 0.42) among
singleton girls.
Conclusions
Our findings suggest that antenatal depression was associated with lower weight
and smaller height only for boys, while postnatal depressive symptom was associated with
higher weight-for- height only for girls. Timing of depression and the mechanisms of
sex-specific responses require further examination.
