Relação entre determinantes sócio-econômicos e hábitos bucais: influência na oclusão de pré-escolares de Bauru - SP - Brasil

Social and biological early life influences on the prevalence of open bite in Brazilian 6‐year‐olds

“…In this study, socioeconomic conditions were not associated with open bite. This corroborates results from other studies 11,[17][18][19] . In spite of this, further research is needed because other studies have not found significant associations between socioeconomic factors and different types of malocclusion 19,20 .…”

“…Birth weight, a key determinant in child health, was not associated with open bite, corroborating another Brazilian study 11 . This finding supports the hypothesis that biological factors in early life have a relatively small effect compared to behavioural ones.…”

“…The analytical approach using the hierarchical model emphasizes the theoretical hypothesis as well as the statistical technics. Open bite affected 46.3% of the sample, a higher prevalence rate than that found in most previous studies 11,15,16 . Variations in prevalence could be explained by the differences in children's ages between studies.…”

“…A minimum sample size to estimate the prevalence of open bite was randomly selected from the 1998 follow-up study sample ( n = 1273). Since the detection rate of the relative risk of anterior open bite is ≥ 1.9, with a prevalence of 54% in children breast-fed for less than 9 months (exposed) 11 , a sample of 342 children was needed, providing a power test of 80% at a significance level of 5%. The sample was increased by 10% to allow for losses or refusals, resulting in a round number of 400 children.…”
