BackgroundHigh postpartum weight retention is a strong independent risk factor for lifetime obesity, cardiovascular disease, and type 2 diabetes in women. Interventions to promote postpartum weight loss have met with some success but have been limited by high attrition. Internet-based treatment has the potential to overcome this barrier and reduce postpartum weight retention, but no study has evaluated the effects of an internet-based program to prevent high postpartum weight retention in women.Methods/DesignFit Moms/Mamás Activas targets recruitment of 12 Women, Infants and Children (WIC) Supplemental Nutrition Program clinics with a total of 408 adult (>18 years), postpartum (<1 year) women with 14.5 kg or more weight retention or a body mass index of 25.0 kg/m2 or higher. Clinics are matched on size and randomly assigned within county to either a 12-month standard WIC intervention or to a 12-month WIC enhanced plus internet-based weight loss intervention. The intervention includes: monthly face-to-face group sessions; access to a website with weekly lessons, a web diary, instructional videos, and computer-tailored feedback; four weekly text messages; and brief reinforcement from WIC counselors. Participants are assessed at baseline, six months, and 12 months. The primary outcome is weight loss over six and 12 months; secondary outcomes include diet and physical activity behaviors, and psychosocial measures.DiscussionFit Moms/Mamás Activas is the first study to empirically examine the effects of an internet-based treatment program, coupled with monthly group contact at the WIC program, designed to prevent sustained postpartum weight retention in low-income women at high risk for weight gain, obesity, and related comorbidities.Trial registrationThis trial was registered with Clinicaltrials.gov (identifier: NCT01408147) on 29 July 2011.

Objective: Irisin is a novel myokine that seems to mediate the beneficial effects of exercise. Levels of circulating irisin before and after an 8-month physical activity program (PAP) in school-age children were evaluated. Methods: Irisin and leptin were measured at baseline and at follow-up among 85 children with different BMI. Results: Of the 85 children (mean age 8.9; 47% female), 25 children had normal weight, 23 were overweight, and 37 had obesity. We observed no significant difference in irisin serum levels between boys and girls. Irisin was positively associated with BMI before and after the PAP (r before 5 0.42; r after 5 0.37, P < 0.001), with the highest levels in children with obesity. There was a slight decrease of circulating irisin after PAP, but this decrease was not of statistical significance. We observed a high and positive association between irisin and leptin levels before and after the PAP (r before 5 0.78; r after 5 0.82, P < 0.001). Moreover, changes in leptin correlated with changes in irisin (r 5 0.72, P < 0.001). Conclusions: Circulating irisin is positively linked to BMI and leptin in school-age children, supporting the notion that that irisin is produced by adipose tissue. As in previous reports, this study failed to observe changes in irisin levels after exercise, likely because higher irisin levels are produced only during exercise.

Higher acculturation was associated with poorer diet and physical activity behaviors and greater PPWR.

The emotional intelligence of a sample of 59 women caregivers (M age = 51.1 yr.) with depressive symptoms was compared with that of a sample of adult women from the general population (M age = 50.7 yr.). No group differences were observed on the Trait Meta-Mood Scale's three dimensions of emotional intelligence across age, socioeconomic status, or education level. Compared with the general population sample, the caregivers group scored significantly lower on Attention to Feelings and Mood Repair.
