Objective To examine factors related to attendance of Mexican‐heritage parents at community‐based nutrition classes to prevent childhood obesity. Methods Starting in 2011, interviewers collected baseline data from Niños Sanos Familia Sana (Healthy Children, Healthy Families) participants in rural California. Educators maintained attendance logs from 2012 to 2014. Informed by the Theory of Planned Behavior, interviewers administered an exit survey in 2015 to collect data on attitudes, subjective norms, health motivations, and perceived control related to attendance. Multivariable ordinal logistic regression analysis examined the correlates of attendance (n = 194, intervention group only). Results Controlling for mother's age, marital status, acculturation, and employment, attitudes and subjective norms were significantly related to attendance (odds ratio = 1.27; 95% confidence interval [CI], 1.18–1.37; P < .001). Conclusions and Implications In these Mexican‐heritage participants, attitudes and subjective norms were significant correlates of attendance. The Theory of Planned Behavior may shed light on attendance of high‐risk groups but further testing of instruments is needed.
