    Background. Antiobesity interventions have generally failed. Research now suggests that interventions must be informed by an understanding of the social environment. Objective. To examine if new social networks form between families participating in a group-level pediatric obesity prevention trial. Methods. Latino parent-preschool child dyads (N = 79) completed the 3-month trial. The intervention met weekly in consistent groups to practice healthy lifestyles. The control met monthly in inconsistent groups to learn about school readiness. UCINET and SIENA were used to examine network dynamics. Results. Children's mean age was 4.2 years (SD = 0.9), and 44% were overweight/obese (BMI ≥ 85th percentile). Parents were predominantly mothers (97%), with a mean age of 31.4 years (SD = 5.4), and 81% were overweight/obese (BMI ≥ 25). Over the study, a new social network evolved among participating families. Parents selectively formed friendship ties based on child BMI z-score, (t = 2.08; P < .05). This reveals the tendency for mothers to form new friendships with mothers whose children have similar body types. Discussion. Participating in a group-level intervention resulted in new social network formation. New ties were greatest with mothers who had children of similar body types. This finding might contribute to the known inability of parents to recognize child overweight

    People and places shaping food procurement among recipients of Supplemental Nutrition Assistance Program (SNAP)

    A key gap in existing food environment research is a more complex understanding of the interplay between physical and social contexts, including the influence of social networks on food habits. This mixed methods research examined the nature of social connections at food procurement places among a sample of 30 people receiving Supplemental Nutrition Assistance Program (SNAP) benefits in an urban setting. Results highlight the significance of social connections as motivators to use food places, the value of access to information and other resources at food places, and the role of weak ties with actors within food places to facilitate utilization and interaction. Social connections at the varied places individuals procure food may be leveraged to disseminate information and resources to further healthy food access.Fil: Monteban, Madalena

    Transcriptomic landscape of the blastema niche in regenerating adult axolotl limbs at single-cell resolution

    No full text
    Limb regeneration requires a blastema with progenitor cells, immune cells, and an overlying wound epidermis, but molecular identities of these populations are unclear. Here, the authors use single-cell RNA-sequencing to identify transcriptionally distinct cell populations in adult axolotl limb blastemas
