Effects of the Sleep SAAF responsive parenting intervention on rapid infant weight gain: A randomized clinical trial of African American families.

Responsive parenting (RP) interventions reduce rapid infant weight gain but their effect for underserved populations is largely unknown. The Sleep SAAF (Strong African American Families) study is a two-arm randomized clinical trial for primiparous African American mother-infant dyads that compares an RP intervention to a child safety control over the first 16 weeks postpartum. Here we report on intervention effects on rapid infant weight gain and study implementation. Families were recruited from a mother/baby nursery shortly after delivery. Community Research Associates (CRAs) conducted intervention home visits at 3 and 8 weeks postpartum, and data collection home visits at 1, 8, and 16 weeks postpartum. To examine rapid infant weight gain, conditional weight gain (CWG) from 3 to 16 weeks, the primary outcome, and upward crossing of 2 major weight-for-age percentile lines were calculated. Among the 212 mother-infant dyads randomized, 194 completed the trial (92% retention). Randomized mothers averaged 22.7 years, 10% were married, and 49% participated in the Supplemental Nutrition Assistance Program (SNAP). Adjusting for covariates, mean CWG was lower among RP infants (0.04, 95% CI [-0.33, 0.40]) than among control infants (0.28, 95% CI [-0.08, 0.64]), reflecting non-significantly slower weight gain (p = 0.15, effect size d = 0.24). RP infants were nearly half as likely to experience upward crossing of 2 major weight-for-age percentile lines (14.1%) compared to control infants (24.2%), p = 0.09, odds ratio = 0.52 (95% CI [0.24, 1.12]). Implementation data revealed that participating families were engaged in the intervention visits and intervention facilitators demonstrated high fidelity to intervention materials. Findings show that RP interventions can be successfully implemented among African American families while suggesting the need for modifications to yield stronger effects on infant weight outcomes.

The Protecting Strong African American Families Program: a Randomized Controlled Trial with Rural African American Couples.

This study presents results from a randomized controlled trial of the Protecting Strong African American Families (ProSAAF) program, a family-centered intervention designed to promote strong couple, coparenting, and parent-child relationships in two-parent African American families. A total of 346 African American couples with an early adolescent child participated; all families lived in rural, low-income communities in the southern USA. Intent-to-treat growth curve analyses involving three waves and spanning 17 months indicated that ProSAAF participants, compared with control participants, reported greater improvements in relationship communication, confidence, satisfaction, partner support, coparenting, and parenting. More than 80% of the couples attended all six of the in-home, facilitator-led sessions; costs to implement the program averaged $1739 per family. The findings inform the ongoing debate surrounding prevention programs for low-income and ethnic minority couples.

The strong African American families-teen trial: rationale, design, engagement processes, and family-specific effects.

This study addresses two limitations in the literature on family-centered intervention programs for adolescents: ruling out nonspecific factors that may explain program effects and engaging parents into prevention programs. The Rural African American Families Health project is a randomized, attention-controlled trial evaluating the efficacy of the Strong African American Families-Teen (SAAF-T) program, a family-centered risk-reduction intervention for rural African American adolescents. Rural African American families (n = 502) with a 10th-grade student were assigned randomly to receive SAAF-T or a similarly structured, family-centered program that focused on health and nutrition. Families participated in audio computer-assisted self-interviews at baseline and 6-month follow-up. Program implementation procedures yielded a design with equivalent doses, five sessions of family-centered intervention programming for families in each condition. Of eligible families screened for participation, 76% attended four or five sessions of the program. Consistent with our primary hypotheses, SAAF-T youth, compared to attention-control youth, demonstrated higher levels of protective family management skills, a finding that cannot be attributed to nonspecific factors such as aggregating families in a structured, interactive setting.
