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.
