A psychometric network perspective to oral health literacy: Examining the replicability of network properties across the general community and older adults from Brazil.

OBJECTIVES: To evaluate the replicability of oral health literacy (OHL) network models across the general community and a sample of older adults from Brazil. METHODS: Data were obtained from two oral health surveys conducted with a total of 1138 participants. OHL was measured using the short form Health Literacy in Dentistry scale (HeLD-14). A regularized partial correlation network was estimated for each sample. Dimensionality and structural stability were examined via exploratory graph analysis. Network properties compared included global strength, edge weights, and centrality estimates. Model replicability was examined fitting the general community model to the older participants' data. RESULTS: Six dimensions with the exact same item composition were detected in both network models. Only the Receptivity domain in the older adults sample yielded low structural stability. Strong correlations were observed between edge weights (τ: 0.68; 95% CI: 0.62-0.74) and between node strength estimates (τ: 0.63; 95% CI: 0.36-0.89). No statistically significant differences were found for global strength. The fit of the older adults sample to the HeLD-14 network structure of the general community sample was satisfactory. CONCLUSION: Network models OHL replicated across the general community and a sample of older adults. The psychometric network approach is a useful tool to evaluate the measurement equivalence of OHL instruments across populations.

Dynamics in oral health-related factors of Indigenous Australian children: A network analysis of a randomized controlled trial.

OBJECTIVES: Network analysis is an innovative, analytic approach that enables visual representation of variables as nodes and their corresponding statistical associations as edges. It also provides a new way of framing oral health-related questions as complex systems of variables. We aimed to generate networks of oral health variables using epidemiological data of Indigenous children, and to compare network structures of oral health variables among participants who received immediate or delayed delivery of an oral health intervention. METHODS: Epidemiological data from 448 mother-child dyads enrolled in a randomized controlled trial of dental caries prevention in South Australia, Australia, were obtained. Networks were estimated with nodes representing study variables and edges representing partial correlation coefficients between variables. Data included dental caries, impact on quality of life, self-rated general health, self-rated oral health, dental service utilization, knowledge of oral health, fatalism and self-efficacy in three time points. Communities of nodes, centrality, clustering coefficient and network stability were estimated. RESULTS: The oral health intervention interacted with the network through self-rated general health and knowledge of oral health. Networks depicting groups shortly after receiving the intervention presented higher clustering coefficients and a similar arrangement of nodes. Networks tended to return to a preintervention state. CONCLUSION: The intervention resulted in increased connectivity and changes in the structure of communities of variables in both intervention groups. Our findings contribute to elucidating dynamics between variables depicting oral health networks over time.

Prevalence and associated factors with integrative and complementary practices use in Brazil.

The aim of the current study was to investigate the prevalence of the use the integrative and complementary practices (ICP) and its associated factors in Brazil. Data was obtained from the cross-sectional National Health Survey 2013 (NHS), which had 145,580 adults aged 18 or over were interviewed. The outcome was the use of any ICP over the last 12 months and independent variables were macro-region, sex, age, educational attainment, skin color/race, and chronic disease. The results show that the prevalence of ICPs use in Brazil was 4.1%, while the most used types were medicinal plants and phytotherapy (2.5%), acupuncture (0.9%) and homeopathy (0.6%). The prevalence of ICPs use was higher in the North Region, among older people, women, participants with higher educational attainment, and with a higher number of chronic diseases. The findings from the current study provide valuable evidence that can inform future evidence-based public policies in Brazil.
