Significance tests for continuous variables are unpaired two-sample t-tests assuming unequal variances; for binary or categorical, chi-squares tests were performed. *p < 0.05, **p < 0.01. pBMI, percentile body mass index; BMI, body mass index. Example interpretations: In 52.7% of food secure families, the target child was female, where the target child was female in only 30.8% of food insecure families. This difference in proportion by food security status (52.7% vs. 30.8%) is statistically significant at p = 0.016. The average morning stress rating among parents in food secure families is 0.58 where the average rating among parents in food insecure families is 0.90. This difference in means by food security status (0.58 vs. 0.90) is statistically significant at p < 0.001.
