Abstract:
Objectives: To evaluate the effect of an intervention on lifestyles (adherence to the Mediterranean diet and promotion of physical activity) carried out in participants of the PREDIMED-PLUS study in their cohabitants (Halo-1). Assess the relationship between socioeconomic deprivation index and lifestyle (diet and physical activity) in a sub-sample of participants in the PREDIMED-PLUS study (Halo-2). Study Halo-1: Design and methods: This cross-sectional study aims to evaluate the association between the PREDIMED-Plus study lifestyle intervention and adherence to the Mediterranean diet (DietMed) and physical activity of cohabiting study participants, and to define the related social characteristics of the household members. Participants were a subsample of 541 cohabitants of the PREDIMED-Plus study. Adherence to the DietMed, physical activity, anthropometric measurements, family function, and social support were assessed. Multiple linear regressions were applied to the data. Using multiple lineal regressions, an increase in the adherence to the DietMed of the PREDIMED-Plus participant, and better family function, were positiv Study Halo-2: Design and methods: This baseline cross-sectional analysis from data acquired in a sub-sample of the PREDIMED-Plus study participants aimed to evaluate the relation between the Composite Socioeconomic Index (CSI) and lifestyle (diet and physical activity). This study involved 1512 participants (52.2% women) between 55 and 80 years with overweight/obesity and metabolic syndrome assigned to 137 primary healthcare centers in Catalonia, Spain. CSI and lifestyle (diet and physical activity) were assessed. Two a posteriori dietary patterns were identified by cluster analysis and labeled as “healthy” and “unhealthy”. In addition, the multinomial regression model showed that a high deprivation index was related to an unhealthy dietary pattern and low physical activity (OR 1.42 [95% CI 1.06–1.89]; p-value < 0.05). Conclusions: The PREDIMED-Plus intervention showed a positive association with adherence to the DietMed of the study participants’ partners. In addition, this association was influenced by the social characteristics of the household membres (Study Halo-1). A high deprivation index was related to an unhealthy lifestyle in PREDIMED-Plus study participants (Study Halo-2).
