Serum micronutrient status, sleep quality and neurobehavioural function among early adolescents.

ABSTRACT:

Objective

To examine associations between serum micronutrients and neurobehavioural function and the mediating role of sleep quality in early adolescents.

Design

In this cross-sectional study, peripheral blood samples were analysed for Fe and Zn levels. The Pittsburgh Sleep Quality Index and Penn Computerized Neurocognitive Battery were used to assess sleep quality and neurobehavioural function, respectively. The logistic/linear regressions and generalised structural equation modelling were performed to estimate the associations.

Setting

Jintan, China.

Participants

In total, 226 adolescents (106 females) from the Jintan Child Cohort study.

Results

Adolescents with low Fe (<75 μg/dl) (OR = 1·29, P = 0·04) and low Zn (<70 μg/dl) (OR = 1·58, P < 0·001) were
