Community health worker intervention to improve tooth brushing in young children: Results from a cluster randomized controlled trial.

OBJECTIVES: Coordinated Oral health Promotion (CO-OP) Chicago is a cluster randomized controlled trial testing the efficacy of a community health worker (CHW) intervention to improve tooth brushing in low-income children. METHODS: Four hundred twenty children under 3 years old (mean 21.5 months) were recruited from 20 sites in or near Chicago, IL. Children were identified mainly as Black race (41.9%) or Hispanic ethnicity (53.8%) and most (85.2%) had Medicaid. Intervention families were offered four CHW home visits over 1 year. Brushing frequency was self-reported. Plaque score was determined from images collected in homes using disclosing solution. Analyses used GEE logistic models with variable selection at p < .05. RESULTS: At enrolment, 45.0% of families reported twice a day or more child brushing frequency, and child plaque scores were poor (mean of 1.9, SD: 0.6). Data were obtained from 87.1% of children at 6 months and 86.2% at 12 months. In the CHW intervention arm (10 sites, N = 211), 23.7% received 4 visits, 12.8% 3 visits, 21.3% 2 visits, 23.2% 1 visit and 19% no visits from CHWs. No intervention effect was seen for brushing frequency or plaque score. Child brushing frequency improvement over time was associated with a range of child and caregiver factors. The only factor associated with a change in plaque score over time was parent involvement in brushing. CONCLUSIONS: Oral-health-specific CHW services were not associated with improved brushing behaviours in these young children. However, caregiver involvement with brushing supported more quality brushing. More robust interventions are needed to support families during this critical developmental period.

Association between neighborhood disadvantage and children's oral health outcomes in urban families in the Chicago area.

Purpose: The prevalence of childhood caries in urban Chicago, compared with national and state data, indicates that neighborhood context influences oral health. Our objective was to delineate the influence of a child's neighborhood on oral health outcomes that are predictive of caries (toothbrushing frequency and plaque levels). Methods: Our study population represents urban, Medicaid-enrolled families in the metropolitan Chicago area. Data were obtained from a cohort of participants (child-parent dyads) who participated in the Coordinated Oral Health Promotion (CO-OP) trial at 12 months of study participation (N = 362). Oral health outcomes included toothbrushing frequency and plaque levels. Participants' neighborhood resource levels were measured by the Area Deprivation Index (ADI). Linear and logistic regression models were used to measure the influence of ADI on plaque scores and toothbrushing frequency, respectively. Results: Data from 362 child-parent dyads were analyzed. The mean child age was 33.6 months (SD 6.8). The majority of children were reported to brush at least twice daily (n = 228, 63%), but the mean plaque score was 1.9 (SD 0.7), classified as "poor." In covariate-adjusted analyses, ADI was not associated with brushing frequency (0.94, 95% CI 0.84-1.06). ADI was associated with plaque scores (0.05, 95% CI 0.01-0.09, p value = 0.007). Conclusions: Findings support the hypothesis that neighborhood-level factors influence children's plaque levels. Because excessive plaque places a child at high risk for cavities, we recommend the inclusion of neighborhood context in interventions and policies to reduce children's oral health disparities. Existing programs and clinics that serve disadvantaged communities are well-positioned to support caregivers of young children in maintaining recommended oral health behaviors.

Oral community health worker-led interventions in households with average levels of psychosocial factors.

Introduction: Household-level psychosocial stress levels have been linked to child tooth brushing behaviors. Community health worker (CHW) interventions that target psychosocial factors in high-risk communities have been associated with changes in health behaviors. Aim: Observe changes in psychosocial factors over time and an association between psychosocial factors and CHW intervention dose amongst urban Chicago families. Patients and methods: Participants (N = 420 families) were recruited from 10 community clinics and 10 Women, Infants, or Children (WIC) centers in Cook County, Illinois to participate in a clinical trial. Research staff collected participant-reported psychosocial factors (family functioning and caregiver reports of depression, anxiety, support, and social functioning) and characteristics of CHW-led oral health intervention visits (number, content, child engagement) at 0, 6, and 12 months. CHWs recorded field observations after home visits on household environment, social circumstances, stressors, and supports. Results: Participants across the cohort reported levels of psychosocial factors consistent with average levels for the general population for nearly all measures. Psychosocial factors did not vary over time. Social functioning was the only measure reported at low levels [32.0 (6.9); 32.1 (6.7); 32.7 (6.9); mean = 50 (standard deviation)] at 0, 6, and 12 months. We did not observe a meaningful difference in social functioning scores over time by exposure to CHW-led intervention visits (control arm, 0, 1, 2, 3, and 4 visits). Field observations made by CHWs described a range of psychosocial stress related to poverty, language barriers, and immigration status. Conclusion: The unexpectedly average and unchanging psychosocial factors over time, in the context of field observations of stress related to poverty, lack of support, immigration status, and language barriers, suggests that our study did not adequately capture the social determinants of health related to oral health behaviors or that measurement biases precluded accurate assessment. Future studies will assess psychosocial factors using a variety of instruments in an attempt to better measure psychosocial factors including social support, depression, anxiety, functioning, trauma and resilience within our urban population. We will also look at neighborhood-level factors of community distress and resilience to better apply the social ecologic model to child oral health behaviors.
