Parenting practices and oral impact on daily performance in southern Brazil.

OBJECTIVES: To explore the relationship between parents' practices and the oral health-related quality of life of children according to the child's point of view. METHODS: It is a cross-sectional study with all children (response rate 75.6 percent, n = 329) from fourth grade of Elementary School to the third grade of High School in 2016 in a small city of southern Brazil. Oral health related quality of life was measured using the oral impact on daily performances (OIDP) using the prevalence of any impact as outcome (OIDP score > 0). Seven parenting practices were evaluated by the inventory of parenting Styles for both father and mother. Logistic regression models were fitted to estimate the association of each parenting practice with OIDP score > 0, and adjusted by sex, age, family equivalent income, mother and father's educational level. RESULTS: About 55.3 percent of the children had at least one impact on daily performances. Respectively, the parenting practices with the highest and lowest percentage for both parents' risk behavior was physical abuse (28.8 percent) and negative monitoring (7.8 percent), while families in which both parents' risk behavior for negligence was 14.7 percent. In the adjusted models, families in which both parents' risk behavior on negligence [odds ratio (OR) = 2.74, 95% confidence intervals (95%CI): 11.27-6.23] and physical abuse (OR = 2.16, 95%CI: 1.13-4.19) and (lack of) positive monitoring (OR = 2.99, 95%CI: 1.32-7.40) had a greater impact on daily life compared to those in which no parents' had risk behavior. CONCLUSIONS: Having any impact on OIDP was associated with negligence, physical abuse, and lack of monitoring among children and adolescents.

Decomposing early and adult life social position effects on oral health and chronic diseases in a cross-sectional study of Southern Brazil.

OBJECTIVES: As the socio-economic trajectory can influence on individual health during the life course, the aim of this study was to test a model of socio-economic life course effects on chronic diseases, tooth loss and on oral health-related quality of life using structural equation model (SEM) to decompose direct and indirect effects. METHODS: This cross-sectional study was performed in southern Brazil, within public healthcare users with 18 years old or more (n = 433). Latent variables were the Oral Health Impact Profile (OHIP), Childhood Socio-economic Status (SESC) and Adulthood (SESA), and Chronic Diseases (CD), and observed variables were sex, age, smoking status and tooth loss. The statistical analysis was performed using structural equation modelling (SEM) using WLSMV estimator. For the final model, we kept only plausible significant paths with P < 0.30. RESULTS: Final model presented an adequate fit: RMSA 0.03, Comparative Fit Index (CFI) 0.97, TLI 0.97, and Weighted Root Mean Square Residual (WRMR) 1.19. The direct effect from SESC to tooth loss was ß = -0.08 (P = 0.19) and the indirect was ß = -0.12 (P = 0.02). The indirect effect from SESC to OHIP was ß = -0.14 (P = 0.01) and there is no direct effect. The direct effect from SESA to tooth loss was ß = -0.21 (P < 0.01) and there is no indirect effect. The direct effect from SESA to OHIP was ß = -0.14 (P = 0.05). The association of SESA on SESC was ß = 0.59 (P < 0.01). CONCLUSIONS: SESC had indirect effects on OHIP and number of teeth via SESA, supporting the chain of effects theory, but not for chronic diseases.
