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

Abstract

Abstract 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<0.05) were entered into stepwise multivariable linear regressions adjusting for infant sex, mother’s education, breastfeeding, and 1-month BISQ-R to determine which HOME subscales were associated with 6- and 12-month total BISQ-R if the total HOME was significant. 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<0.001). The regression of 1-month HOME subscales with 6-month BISQ-R indicated greater BISQ-R scores were associated with shorter breastfeeding (β=-0.31, p=0.001), greater Responsivity scores (β=0.21, p=0.022), and 1-month BISQ-R scores (β=0.2, p=0.027), which explained 13.9% of the variance (F[3,106]=6.86, p<0.001). The regression of 1-month HOME with 12-month BISQ-R indicated greater BISQ-R scores were associated with shorter breastfeeding (β=-0.24, p=0.013) and greater HOME total scores (β=0.24, p=0.016), which explained 7.9% of the variance (F[2,100]=5.4, p=0.006). The regression of 1-month HOME subscales with 12-month BISQ-R indicated greater BISQ-R scores were associated with greater Variety scores (β=0.29, p=0.003), shorter breastfeeding (β=-0.24, p=0.011), and 1-month BISQ-R scores(β=0.18, p=0.049), which explained 13.5% of the variance (F[3,99]=6.29, p=0.001). Conclusion Better infant sleep was associated with an early interactive home environment, especially parent’s responsiveness and people/events providing organized variety. Support (if any):
