To identify adherence required to achieve target health outcome(s) in nutrition and/or exercise interventions, a measurement tool that tracks objective and self-reported measures of adherence is necessary. The purpose of this study was to design an adherence measurement tool and test it retrospectively on the Nutrition and Exercise Lifestyle Intervention Program (NELIP; Ruchat et al., Medicine and Science in Sports and Exercise, 44(8), 1419–1426, 2012; Mottola et al., Medicine and Science in Sports and Exercise, 42(2), 265–272, 2010), designed to prevent excessive gestational weight gain (EGWG). The tool was based on the goals of the NELIP and included a grading system for each behavior (exercise and nutrition). It was used to determine whether adherence scores could differentiate excessive versus acceptable weight gain during pregnancy across pre-pregnancy body mass index (BMI) categories. Results showed irrespective of pre-pregnancy BMI, women with acceptable weight gain had significantly higher adherence (p < 0.05) than women with excessive weight gain. It is recommended that this adherence tool be included in future prospective lifestyle intervention studies.
