Multilevel Factors Associated With Participation in Group Well-Child Care

OBJECTIVE: To identify factors associated with participation in group well-child care (GWCC), wherein families share preventive health care visits.METHODS: We extracted electronic health record data of mother-infant dyads with infants born 2013-18 at Yale New Haven Hospital and followed at the primary care center. Using chi-square analysis and multivariate logistic regression, we examined the extent to which 1) maternal/infant characteristics and recruitment timing were associated with GWCC initiation and continued engagement and 2) initiation was associated with primary care visits.RESULTS: Of 2046 eligible mother-infant dyads, 11.6% initiated GWCC. The odds of initiation were higher among mothers with Spanish versus English primary language (odds ratio: 2.36 [95% confidence interval: 1.52-3.66]), with 1 child versus >= 3 children (1.58 [1.13-2.22]), and of non-Hispanic Black versus non-Hispanic White infants (2.72 [1.39-5.32]). Initiation was lower among infants born in 2016 (0.53 [0.32-0.88]) and 2018 (0.29 [0.17-0.52]) versus 2013. Among GWCC initiators with follow-up data (n = 217), continued engagement (n = 132, 60.8%) was positively associated with maternal age of 20-29 years (2.85 [1.10-7.34]) and > 30 years (3.46 [1.15-10.43]) compared with < 20 years, and mothers with 1 child versus >= 3 (2.28 [1.04-4.98]). GWCC initiators, versus non-initiators, had 5.06 times higher adjusted odds of attending > 9 primary care appointments in the first 18 months (95% confidence interval: 3.74-6.85).CONCLUSIONS: As evidence builds on health and social benefits of GWCC, recruitment efforts may gain from con- sidering multi-level socio-economic, demographic, and cultural factors associated with GWCC participation. Higher partici- pation among systemically marginalized groups may present unique opportunities for family-based health promotion to mitigate health inequities.
