Higher scores on the index indicate higher levels of behavioral problems. The first BPI category is the first quartile with fewest behavioral problems, the second represents the second quartile, the third catergory is median to <90 percentile, and the fourth category is ≥90th percentile reflecting serious behavioral problems.
2Differences in the prevalence of each health outcome across the BPI categories were statistically significant at P < 0.05. 3A composite variable denoting parenting aggravation if parents reported in the past month that child was much harder to care for, or were bothered by child's behavior, or felt angry with their child.
