School-Based Caries Prevention, Tooth Decay, and the Community Environment

Ruff, R R; Niederman, R
The school and community context can contribute to inequity in child oral health. Whether the school and community affect the effectiveness of school-based caries prevention is unknown. The association between the school and community environment and dental caries, as well as their moderating effects with school-based caries prevention, was assessed using multilevel mixed-effects regression. Data were derived from a 6-y prospective cohort study of children participating in a school-based caries prevention program. For the school and community, living in a dental-shortage area and the proportion of children receiving free or reduced lunch were significantly related to an increased risk of dental caries at baseline. Caries prevention was associated with a significant per-visit decrease in the risk of untreated caries, but the rate of total caries experience increased over time. Caries prevention was more effective in children who had prior dental care at baseline and in schools with a higher proportion of low socioeconomic status students. There was significant variation across schools in the baseline prevalence of dental caries and the effect of prevention over time, although effects were modest. The school and community environment have a direct impact on oral health and moderate the association between school-based caries prevention and dental caries.Knowledge Transfer Statement:School-based caries prevention can be an effective means to reduce oral health inequity by embedding dental care within schools. However, the socioeconomic makeup of schools and characteristics of the surrounding community can affect the impact of school-based care.

Surgical Care for School-Aged Youth With Cleft: Results From a Multicenter, Prospective Observational Study

Ruff, Ryan Richard; Crerand, Canice E; Sischo, Lacey; Peshansky, Alexandre; Sarwer, David B; Kirschner, Richard E; Broder, Hillary L
OBJECTIVE:To explore factors related to completion of surgery recommendations among children with cleft lip and palate (CLP) or cleft palate only (CPO). DESIGN/METHODS:Multicenter prospective longitudinal cohort study (2009-2015). SETTING/METHODS:Six cleft centers in the United States. PATIENTS/PARTICIPANTS/METHODS:A diverse sample of 1186 youth aged 7.5 to 18.5 years with CLP or CPO and a caregiver. RESULTS:Data were collected from child-caregiver dyads at baseline and up to 3 follow-up visits. Of the 765 surgeries recommended during the study period, 83 were postponed and 597 were completed; this represents a completion rate of 78%. There were multiple reasons identified by patients for why the remaining 85 recommended surgeries were not completed. Children with nonprivate insurance were more likely to postpone recommended surgeries. Hispanic/Latino and Asian children had fewer surgeries compared to whites/Caucasians. Greater severity in rated speech differences was associated with more surgeries. Among participants who had completed all recommended surgeries, providers rated over 86% as having normal or mildly different facial appearance and 83% as having a normal or mild speech intelligibility rating. Similarly, caregivers rated 80% of facial appearance and 78% of speech positively. Approximately 25% of children had an additional surgical recommendation at the end of the study. CONCLUSIONS:The majority of surgical recommendations were completed with positive outcomes in facial appearance and speech intelligibility by provider and caregiver ratings. Several factors contributed to surgical recommendations not being completed and the results underscore the importance of examining socioeconomic and demographic disparities in surgical care.

Neighborhood Stigma and Sleep: Findings from a Pilot Study of Low-Income Housing Residents in New York City

Ruff, Ryan Richard; Ng, Jeannie; Jean-Louis, Girardin; Elbel, Brian; Chaix, Basile; Duncan, Dustin T
The primary objective of this study was to investigate the relationship between neighborhood stigma and sleep in a sample of low-income housing residents in New York City. Data were derived from the NYC Low-Income Housing, Neighborhoods, and Health Study (N = 120). Adults living in low-income housing completed a survey consisting of measures of neighborhood stigma, sleep quality, and sleep duration. Neighborhood stigma and sleep were self-reported. Associations between neighborhood stigma and sleep health were analyzed using generalized linear models with cluster variance estimation. Multivariable models adjusted for age, gender, race/ethnicity, income, education, employment status, obesity, the census block percentage of non-Hispanic black residents, and the census block percentage median household income. Results indicate that a reported negative media perception of the neighborhood was negatively associated with sleep quality and duration (p < 0.01). However, additional research is needed to explore neighborhood stigma as it relates to sleep.

Development and validation of the Child Oral Health Impact Profile - Preschool version

Ruff, R R; Sischo, L; Chinn, C H; Broder, H L
OBJECTIVE: The Child Oral Health Impact Profile (COHIP) is a validated instrument created to measure the oral health-related quality of life of school-aged children. The purpose of this study was to develop and validate a preschool version of the COHIP (COHIP-PS) for children aged 2-5. BASIC RESEARCH DESIGN: The COHIP-PS was developed and validated using a multi-stage process consisting of item selection, face validity testing, item impact testing, reliability and validity testing, and factor analysis. PARTICIPANTS: A cross-sectional convenience sample of caregivers having children 2-5 years old from four groups completed item clarity and impact forms. Groups were recruited from pediatric health clinics or preschools/daycare centers, speech clinics, dental clinics, or cleft/craniofacial centers. Participants had a variety of oral health-related conditions, including caries, congenital orofacial anomalies, and speech/language deficiencies such as articulation and language disorders. MAIN OUTCOME MEASURE: COHIP-PS. RESULTS: The COHIP-PS was found to have acceptable internal validity (a = 0.71) and high test-retest reliability (0.87), though internal validity was below the accepted threshold for the community sample. While discriminant validity results indicated significant differences across study groups, the overall magnitude of differences was modest. Results from confirmatory factor analyses support the use of a four-factor model consisting of 11 items across oral health, functional well-being, social-emotional well-being, and self-image domains. CONCLUSIONS: Quality of life is an integral factor in understanding and assessing children's well-being. The COHIP-PS is a validated oral health-related quality of life measure for preschool children with cleft or other oral conditions.

Challenges in conducting multicentre, multidisciplinary, longitudinal studies in children with chronic conditions

Broder, Hillary L; Crerand, Canice E; Ruff, Ryan R; Peshansky, Alexandre; Sarwer, David B; Sischo, Lacey
OBJECTIVES: Conducting longitudinal, multicentre, multidisciplinary research for individuals with chronic conditions can be challenging. Despite careful planning, investigative teams must adapt to foreseen and unforeseen problems. Our objective is to identify challenges encountered and solutions sought in a recently completed observational, longitudinal study of youth with cleft lip and palate as well as their caregivers. METHODS: Data for analysis were derived from a 6-year, multicentre, prospective, longitudinal study of youth with cleft conducted from 2009 to 2015 that examined oral health-related quality of life and other related clinical observations over time in youth who had cleft-related surgery compared to those who did not. Youth and their caregivers participating in this study were followed at one of six geographically diverse, multidisciplinary cleft treatment centres in the USA. RESULTS: Establishing effective communication, ensuring protocol adherence, safeguarding data quality, recognizing and managing differences across sites, maximizing participant retention, dealing with study personnel turnover, and balancing/addressing clinical and research tasks were particularly exigent issues that arose over the course of the study. Attending to process, ongoing communication within and across sites, and investigator and clinician commitment and flexibility were required to achieve the stated aims of the research. CONCLUSION: Studying children with cleft and their caregivers over time created both foreseen and unforeseen challenges. Solutions to these challenges are presented to aid in the design of future longitudinal research in individuals with chronic conditions.

The impacts of retention, expenditures, and class size on primary school completion in Sub-Saharan Africa: A cross-national analysis

Ruff, Ryan
Education in Sub-Saharan Africa is increasingly viewed as a means of emancipation, acting as a transformative project for social mobility. Developing nations have subsequently pursued policies designed to increase access to education and improve upon student outcomes, such as universal or free primary education. In this study, direct and indirect precursors to primary school completion in Sub-Saharan Africa are considered using cross-national data collected by the UNESCO Institute for Statistics. Path analysis results show that imbalanced pupil-teacher ratios and high student retention rates are negatively associated with primary school completion. Additionally, the positive relationship between expenditure increase and completion rates is mediated by a negative contribution to pupil-teacher ratios. Results are compared with existing production function research on varied educational inputs and student success

Minimally important difference of the Child Oral Health Impact Profile for children with orofacial anomalies

Ruff, Ryan Richard; Sischo, Lacey; Broder, Hillary L
BACKGROUND: The Child Oral Health Impact Profile (COHIP) is an instrument designed to measure the self-reported oral health-related quality of life of children between the ages of 8 and 15, including domains for oral health, functional well-being, social-emotional well-being, school environment and self-image. The purpose of this study was to estimate the minimally important difference (MID) of the COHIP for patients with cleft lip/palate. METHODS: Data from a 6-year, prospective, longitudinal cohort study of children with cleft lip/palate were analyzed to estimate the MID. Analysis was restricted to patients with data at baseline and first follow-up and not receiving a surgical intervention in the intervening years (N = 281). MIDs were estimated via the anchor-based method, using the Global Assessment of Change, and the effect size distribution method. RESULTS: Based on the distributional method, the minimally important differences were 0.16 (oral health), 0.12 (functional), 0.22 (social-emotional), 0.21 (school environment) and 0.19 (self-image). MID anchor estimates for COHIP domains ranged from -0.32 to 0.84. The anchor-based and effect size MID estimates for the overall COHIP score were 2.95 and 0.25, respectively. CONCLUSION: The minimally important difference of the Child Oral Health Impact Profile is recommended for interpreting clinically meaningful change in patients with cleft lip/palate.

Perceived spatial stigma, body mass index and blood pressure: a global positioning system study among low-income housing residents in New York City

Duncan, Dustin T; Ruff, Ryan R; Chaix, Basile; Regan, Seann D; Williams, James H; Ravenell, Joseph; Bragg, Marie A; Ogedegbe, Gbenga; Elbel, Brian
Previous research has highlighted the salience of spatial stigma on the lives of low-income residents, but has been theoretical in nature and/or has predominantly utilised qualitative methods with limited generalisability and ability to draw associations between spatial stigma and measured cardiovascular health outcomes. The primary objective of this study was to evaluate relationships between perceived spatial stigma, body mass index (BMI), and blood pressure among a sample of low-income housing residents in New York City (NYC). Data come from the community-based NYC Low-income Housing, Neighborhoods and Health Study. We completed a crosssectional analysis with survey data, which included the four items on spatial stigma, as well objectively measured BMI and blood pressure data (analytic n=116; 96.7% of the total sample). Global positioning systems (GPS) tracking of the sample was conducted for a week. In multivariable models (controlling for individual-level age, gender, race/ethnicity, education level, employment status, total household income, neighborhood percent non-Hispanic Black and neighborhood median household income) we found that participants who reported living in an area with a bad neighborhood reputation had higher BMI (B=4.2, 95%CI: -0.01, 8.3, P=0.051), as well as higher systolic blood pressure (B=13.2, 95%CI: 3.2, 23.1, P=0.01) and diastolic blood pressure (B=8.5, 95%CI: 2.8, 14.3, P=0.004). In addition, participants who reported living in an area with a bad neighborhood reputation had increased risk of obesity/overweight [relative risk (RR)=1.32, 95%CI: 1.1, 1.4, P=0.02) and hypertension/pre-hypertension (RR=1.66, 95%CI: 1.2, 2.4, P=0.007). However, we found no differences in spatial mobility (based GPS data) among participants who reported living in neighborhoods with and without spatial stigma (P>0.05). Further research is needed to investigate how placebased stigma may be associated with impaired cardiovascular health among individuals in stigmatised neighborhoods to inform effective cardiovascular risk reduction interventions.
