^†Population estimates were based on school-level data [source ref. 27].

^¶Free/reduced lunch eligibility was used as an indicator of family income of the school populations. These data indicate that 85% of the students in the two urban schools were eligible and 58.5% of the students in the two urban schools were eligible.

^§Population estimates were based on county-level data from the census [source ref. 28] on the percentage of persons aged ≥25 who were high school graduates. These data include both males and females and may therefore be slightly inaccurate estimates of maternal education.

^‡Body mass index (BMI) n: 61 (mother urban); 51 (father urban); 29 (mother rural); 28 (father rural).
