153 Early Positive Parent-Child Interactions and Enriched Home Environment are Associated with Better Infant Sleep

Introduction Infant sleep is influenced by biopsychosocial interactions. However, the influence of an interactive home environment is underexplored. The aim was to examine whether early positive parent-child interactions and an enriched home environment were associated with better infant sleep later. Methods Pregnant, obese, and low-income Latina women were recruited for a RCT delivering a 12-month intervention for infants to prevent overweight (n=129). At 1, 6, and 12 months, mothers reported breastfeeding duration, completed the Brief Infant Sleep Questionnaire-Revised (BISQ-R, range: 0-100), and underwent the Home Observation for Measurement of the Environment (HOME, range: 0-45) Inventory including subscales of Responsivity, Acceptance, Organization, Learning Materials, Involvement, and Variety. Pearson correlations between HOME and BISQ-R at each visit were conducted. Significant associations (α Results The mean 1-, 6- and 12-month BISQ-R were 84(SD=6.1), 76.4(SD=8.3), and 78.5(SD=8.0), respectively. The 1-month HOME total score (M=21.8[SD=4.4]) significantly correlated with the 6- and 12-month BISQ-R. The regression of 1-month HOME with 6-month BISQ-R indicated greater BISQ-R scores were associated with shorter breastfeeding (β=-0.3, p=0.001), greater HOME total scores (β=0.2, p=0.037), and 1-month BISQ-R scores(β=0.2, p=0.038), which explained 13.1% of the variance (F[3,106]=6.5, p Conclusion Better infant sleep was associated with an early interactive home environment, especially parent’s responsiveness and people/events providing organized variety.
