Note: Source: The National Longitudinal Study of Adolescent Health (Add Health) and Adolescent Health and Academic Achievement Study (AHAA). OLS regression models include control variables signifying the following family and parent characteristics: mother's race and ethnicity, parents' racial homogamy, parents' education level, family income, financial distress, mother' work status, parents' health conditions (obesity, diabetes, asthma or emphysema, and alcoholism), parents' relationship characteristics, parents' religiosity, parents' age, and parents' educational expectations for their child. Models also include indicators of an adolescent's age, gender, number of siblings, educational expectations, academic risk behavior, and attachment to and engagement in school. Other control variables include an indicator of the length of time between Wave I and II interviews and an indicator of missing data on any control variable in the OLS regression model.
