Abstract Background Fatigue is a major issue that affects women during the postpartum period. A healthy dietary pattern and increased physical activity (PA) are commonly recommended lifestyle modifications to promote health during this time. However, little is known about the interrelationship between dairy product intake, PA level, and postpartum fatigue (PPF) among women. The aim of this study was to evaluate whether PPF is associated with dairy product intake in relation to PA level. Methods A total of 242 women were included in this cross-sectional study. Data related to dairy product intake and PA were collected using a food frequency questionnaire and the International Physical Activity Questionnaire—Short Form, respectively. PPF was assessed using the Fatigue Severity Scale. Logistic regression models were used to examine associations between the intake of dairy products and PPF among women engaged in low, moderate, and high levels of PA while controlling for potential confounders. Results Higher consumption rates of yogurt and total dairy predicted lower odds of PPF in women engaged in moderate levels of PA (aOR = 0.24 [95% CI = 0.07, 0.86] and 0.70 [95% CI = 0.53, 0.93], respectively). In women engaged in high levels of PA, lower odds of experiencing PPF were predicted by higher consumption rates of milk (aOR = 0.24 [95% CI = 0.07, 0.89]), yogurt (aOR = 0.21 [95% CI = 0.05, 0.83]), laban (aOR = 0.16 [95% CI = 0.03, 0.86]), and total dairy (aOR = 0.66 [95% CI = 0.47, 0.92]). However, no association was observed between dairy product intake and PPF in women with low levels of PA. Conclusions Higher consumption rates of dairy products were associated with lower odds for experiencing PPF, particularly for women engaged in moderate to high levels of PA. These findings support nutritional and PA promotion programs to moderate issues with PPF. However, the cross-sectional design of this study could limit the ability to infer causality between dairy intake, PA, and PPF. Further longitudinal studies are needed to establish causality and explore the mechanisms underlying these associations.
