A Cluster-Randomized, Community-Based, Tribally Delivered Oral Health Promotion Trial in Navajo Head Start Children.

ABSTRACT: The authors tested the effectiveness of a community-based, tribally delivered oral health promotion (OHP) intervention (INT) at reducing caries increment in Navajo children attending Head Start. In a 3-y cluster-randomized trial, we developed an OHP INT with Navajo input that was delivered by trained Navajo lay health workers to children attending 52 Navajo Head Start classrooms (26 INT, 26 usual care [UC]). The INT was designed as a highly personalized set of oral health-focused interactions (5 for children and 4 for parents), along with 4 fluoride varnish applications delivered in Head Start during academic years of 2011 to 2012 and 2012 to 2013. The authors evaluated INT impact on decayed, missing, and filled tooth surfaces (dmfs) increment compared with UC. Other outcomes included caries prevalence and caregiver oral health-related knowledge and behaviors. Modified intention-to-treat and per-protocol analyses were conducted. The authors enrolled 1,016 caregiver-child dyads. Baseline mean dmfs/caries prevalence equaled 19.9/86.5% for the INT group and 22.8/90.1% for the UC group, respectively. INT adherence was 53% (i.e., ?3 child OHP events, ?1 caregiver OHP events, and ?3 fluoride varnish). After 3 y, dmfs increased in both groups (+12.9 INT vs. +10.8 UC; P = 0.216), as did caries prevalence (86.5% to 96.6% INT vs. 90.1% to 98.2% UC; P = 0.808) in a modified intention-to-treat analysis of 897 caregiver-child dyads receiving 1 y of INT. Caregiver oral health knowledge scores improved in both groups (75.1% to 81.2% INT vs. 73.6% to 79.5% UC; P = 0.369). Caregiver oral health behavior scores improved more rapidly in the INT group versus the UC group (P = 0.006). The dmfs increment was smaller among adherent INT children (+8.9) than among UC children (+10.8; P = 0.028) in a per-protocol analysis. In conclusion, the severity of dental disease in Navajo Head Start children is extreme and difficult to improve. The authors argue that successful approaches to prevention may require even more highly personalized approaches shaped by cultural perspectives and attentive to the social determinants of oral health (ClinicalTrials.gov NCT01116739).

Project description:Purpose: To determine the effectiveness of a train-the-trainer program for Community Oral Health Workers (COHWs) with the goal of reducing Early Childhood Caries (ECC). Methods: Thirteen Latina caregivers from a local Early Head Start program participated in an 8 h bilingual oral health training program that provided information and hands-on experiences pertaining to prenatal and children's oral health. Once trained, the 13 COHWs conducted a series of bilingual interactive oral health promotion workshops at local community sites. Pre/post-tests were conducted after each workshop with a total of 157 caregivers of young children. Bivariate analyses were used to assess changes in knowledge, attitudes, and practices of the COHWs and caregivers regarding children's oral health. Results: Significant positive changes (p < 0.05) in COHWs' knowledge were observed for age a child can brush his/her teeth alone and what a pregnant woman with morning sickness can do to protect her teeth. Positive trends were observed for knowing that tap water with fluoride prevents cavities and that poor oral health of parents affects their children's dental health. While community caregivers in the workshops reported a high consumption of sweet snacks and beverages, there was a significant positive increase (p < 0.05) in knowledge and attitudes regarding oral health care. Significant increases in knowledge were obtained regarding: when a child can brush his/her teeth well alone, the age when fluoridated toothpaste can be used, ways tooth decay can be prevented, when a child's first dental visit should be, and what a pregnant woman with morning sickness can do to protect her teeth. Significant positive improvements were found regarding caregiver's favorable attitude that fluoridated water can help prevent cavities, disagreeing that tap water is dangerous, and agreeing that a parent's dental health affects their children's dental health. Conclusions: The study showed a targeted and culturally competent oral health program can significantly improve knowledge, attitudes, and self-reported practices of COHWs and the caregivers they trained. Although longitudinal studies are needed to determine if a COHW model can help reduce ECC in underserved communities, preliminary results support the utilization of this model as a viable option that should be expanded.

Project description:BackgroundIndividual child-level risk factors for Early Childhood Caries (ECC) have been studied, but broader family- and community-level influences on child oral hygiene behaviors are less well understood. This study explored multiple levels of influence on oral hygiene behaviors for young children in Early Head Start (EHS) to inform a future behavioral intervention targeting children from low-income families.MethodsTwenty-four semi-structured interviews were conducted with mothers of children under 4 years old, enrolled in the home visitor (HV) component of one EHS program in Los Angeles, CA, who participated in the BEhavioral EConomics for Oral health iNnovation pilot study (BEECON) in 2016-7. Audio-recordings of interviews were translated if needed, and transcribed in English, and coding and analysis was facilitated by Dedoose qualitative software. This investigation used general thematic analysis guided by the Fisher-Owens child oral health conceptual framework to identify influences on oral hygiene behaviors for the young children.ResultsMany mothers reported brushing their children's teeth twice/day, and concern that most children frequently resisted brushing. They identified children being sick or tired/asleep after outings as times when brushing was skipped. Several child-, family-, and community-level themes were identified as influences on child oral hygiene behaviors. At the child-level, the child's developmental stage and desire for independence was perceived as a negative influence. Family-level influences included the mother's own oral hygiene behaviors, other family role models, the mother's knowledge and attitudes about child oral health, and mothers' coping skills and strategies for overcoming challenges with brushing her child's teeth. Overall, mothers in the EHS-HV program were highly knowledgeable about ECC risk factors, including the roles of bacteria and sugar consumption, which motivated regular hygiene behavior. At the community-level, mothers discussed opportunities to connect with other EHS-HV families during parent meetings and playgroups that HV coordinated. A few mothers noted that EHS-HV playgroups included brushing children's teeth after snacking, which can be a potential positive influence on children's hygiene practices.ConclusionChild-, family- and community-level factors are important to consider to inform the development of tailored oral health preventive care programs for families in EHS-HV programs.

Project description:ObjectivesThe primary objective of this cluster randomised controlled trial was to compare the effectiveness of the three experimental continence promotion interventions against a control intervention on urinary symptom improvement in older women with untreated incontinence recruited from community organisations. A second objective was to determine whether changes in incontinence-related knowledge and new uptake of risk-modifying behaviours explain these improvements.Setting71 community organisations across the UK.Participants259 women aged 60 years and older with untreated incontinence entered the trial; 88% completed the 3-month follow-up.InterventionsThe three active interventions consisted of a single 60 min group workshop on (1) continence education (20 clusters, 64 women); (2) evidence-based self-management (17 clusters, 70 women); or (3) combined continence education and self-management (17 clusters, 61 women). The control intervention was a single 60 min educational group workshop on memory loss, polypharmacy and osteoporosis (17 clusters, 64 women).Primary and secondary outcome measuresThe primary outcome was self-reported improvement in incontinence 3 months postintervention at the level of the individual. The secondary outcome was change in the International Consultation on Incontinence Questionnaire (ICIQ) from baseline to 3-month follow-up. Changes in incontinence-related knowledge and behaviours were also assessed.ResultsThe highest rate of urinary symptom improvement occurred in the combined intervention group (66% vs 11% of the control group, prevalence difference 55%, 95% CI 43% to 67%, intracluster correlation 0). 30% versus 6% of participants reported significant improvement respectively (prevalence difference 23%, 95% CI 10% to 36%, intracluster correlation 0). The number-needed-to-treat was 2 to achieve any improvement in incontinence symptoms, and 5 to attain significant improvement. Compared to controls, participants in the combined intervention reported an adjusted mean 2.05 point (95% CI 0.87 to 3.24) greater improvement on the ICIQ from baseline to 3-month follow-up. Changes in knowledge and self-reported risk-reduction behaviours paralleled rates of improvement in all intervention arms.ConclusionsContinence education combined with evidence-based self-management improves symptoms of incontinence among untreated older women. Community organisations represent an untapped vector for delivering effective continence promotion interventions.Trial registrationClinicalTrials.gov ID number NCT01239836.
