We examined self-determination theory (SDT) and weight loss, and hypothesized that the Diabetes Prevention Program's (DPP) intervention would result in an increase in autonomous regulation of motivation (AR) in participants. Further, that those with higher AR, and those who perceived educators as supporting SDT-defined needs, would lose more weight. Support, Health Information, Nutrition and Exercise (SHINE) Study data (N = 257) were analyzed. SHINE was a randomized, controlled DPP translation trial (2-years, telephonic, primary care staff). Autonomous motivation in males increased significantly, while females showed no change. Males with high AR, but not females, lost more weight. However, the significance of these relationships varied over time. Participants who perceived educators as more supportive of psychological needs lost more weight (especially males). However, effect of support on weight loss was not mediated by AR change. Autonomous motivation and educator support are relevant to male weight loss. Future research might develop interventions to enhance autonomous motivation and educator support, and understand change pathways.

Objectives The healthy immigrant effect is the phenomenon by which immigrants experience more positive health outcomes than the native-born population in developed countries. The strength of this effect appears to be related to country of origin, health outcome, healthcare and integration policies of receiving countries, as well as immigration class. This secondary analysis of birth records examines whether immigrants and mothers from refugee countries have lower adjusted risk of preterm births than US-born mothers in Syracuse, NY, a preferred refugee resettlement area. Methods This secondary analysis included 6354 electronic birth records for residents in the city of Syracuse, NY who gave birth to singleton infants between 2009 and 2011. Multivariate log-binomial regression was used to calculate the adjusted relative risk for preterm birth among foreign-born mothers and mothers from refugee countries, compared to US-born mothers. Results Infants born to both foreign-born women and to women from refugee countries had decreased risks of being born preterm compared to infants born to US mothers, controlling for race, late/no prenatal care, maternal age less than 18 years and smoking. Conclusion Our findings support a healthy immigrant effect for preterm births both among all foreign-born immigrants and among the subsample of women from refugee countries. Mother’s nativity is likely a proxy for unmeasured factors (e.g., prenatal stress, maternal diet, etc.) that may explain the relationship between mother’s nativity and preterm births. Additional research is needed to better understand the underlying factors.
