Infant Age Moderates Associations Between Infant Temperament And Maternal Technology Use During Infant Feeding And Care, Maya I. Davis, Camille M. Delfosse, Alison K. Ventura

Kinesiology and Public Health

Previous research illustrated that infants’ temperamental traits shape parents’ behaviors, but parents’ behaviors can also elicit or intensify infants’ behaviors in ways that shape temperament. One understudied aspect of parenting that may exhibit bidirectional influences with temperament is parent technology use (e.g., use of mobile devices) within family contexts. To date, few studies have examined whether maternal technology use is associated with infant temperament and whether age-related differences in these associations exist. The present study was a secondary analysis of pooled data from three infant feeding studies. Mothers (n = 374) of young infants (age 16.2 ± 6.2 weeks) …

Faculty Publications

Although physical activity and sedentary behavior are moderately heritable, little is known about the mechanisms that influence these traits. Combining data for up to 703,901 individuals from 51 studies in a multi-ancestry meta-analysis of genome-wide association studies yields 99 loci that associate with self-reported moderate-to-vigorous intensity physical activity during leisure time (MVPA), leisure screen time (LST) and/or sedentary behavior at work. Loci associated with LST are enriched for genes whose expression in skeletal muscle is altered by resistance training. A missense variant in ACTN3 makes the alpha-actinin-3 filaments more flexible, resulting in lower maximal force in isolated type IIA muscle …
