Abbreviations: CI, confidence interval; FPL, federal poverty level.
P value compares estimates between pregnant and nonpregnant women in each category (eg, age, race/ethnicity). A total of 13 pairwise tests between pregnant and nonpregnant women, yielding a Bonferroni corrected cut-off of .05/13 (P = <.004). P values for these tests exceeding .004 should be interpreted with caution on the basis of Bonferroni adjustment for multiple comparisons.
Two sample t tests were used to compare estimates in each category (eg, age, race/ethnicity) for both pregnant and nonpregnant women. P value is greater than .003 but less than .05.
P value compares estimates in each category (eg, age, race/ethnicity) for pregnant and nonpregnant women. A total of 16 pairwise tests between respondent characteristic groups yielded a Bonferroni corrected cut-off of .05/16, P = <.003. P values for these tests exceeding .003 should be interpreted with caution on the basis of Bonferroni adjustment for multiple comparisons. Values in a sociodemographic subgroup (eg, age groups) among either pregnant or nonpregnant women with the same superscript letters (y and z) mean they are significantly different from one another, P < .003 (eg, If the percentage of pregnant women aged 15 to 24 years who answered “yes” to having very good or good mouth and teeth condition is significantly different from the percentage of pregnant women aged 35 to 44 who answered “yes” to having very good or good mouth and teeth condition, they will both have the same superscript letter.
Estimate may not be representative (degrees of freedom = 11).
All racial/ethnic categories are included in the total denominator but not all racial/ethnic categories are presented separately.
Poverty status is defined by the ratio of family income to the federal poverty level.
