Wellness Coaching: An Intervention to Increase Healthy Behavior in Breast Cancer Survivors.

BACKGROUND: Regular physical activity after breast cancer diagnosis improves survival rates and quality of life (QOL). However, breast cancer survivors rarely meet guidelines for recommended levels of physical activity. Wellness coaching interventions (WCIs) have improved exercise and health behaviors in other patient populations. OBJECTIVES: This study assessed the feasibility and effectiveness of WCIs for increasing physical activity in breast cancer survivors; secondary measures included changes in dietary habits, weight, and QOL. METHODS: 20 obese or overweight breast cancer survivors who recently completed active breast cancer treatment were recruited into a single-arm, 12-week WCI pilot feasibility study. The intervention was comprised of one in-person wellness coaching visit followed by four telephone calls over 12 weeks and 12 weekly emails containing wellness recommendations. FINDINGS: Significant improvements from pre- to postintervention were seen in physical activity level, dietary habits, and in some aspects of QOL. Forty percent of participants achieved the 3% postintervention weight-loss goal, but this was not sustained at 30 weeks.

Family-Based Mindful Eating Intervention in Adolescents with Obesity: A Pilot Randomized Clinical Trial.

Mindfulness has gained attention in the treatment of obesity. However, there is a paucity of data on family-based training in mindful eating in children. The objective of this pilot randomized clinical trial was to evaluate the feasibility and acceptability of a family-based mindful eating intervention (MEI) in adolescents with obesity, and to compare the efficacy of the MEI versus standard dietary counseling (SDC) for decreasing weight and improving cardiometabolic risk markers. Twenty-two adolescents (age 14.5⁻17.9 years) and parent pairs were randomized to the MEI or SDC. The MEI was administered in four 90-min sessions over 10 weeks and SDC was provided at baseline, 12 weeks, and 24 weeks. Despite the requirement of more frequent visits with the MEI, adolescents and parents attended 100% of the sessions and there were no dropouts in that group. High density lipoprotein (HDL) cholesterol increased in the SDC group, but not in the MEI group. Adolescents receiving the MEI demonstrated an increase in awareness at 24 weeks (p = 0.01) and a decrease in distraction during eating at 12 weeks (p = 0.04), when compared with the SDC group. The family-based MEI showed feasibility and acceptability in adolescents with obesity. Future studies with more intense therapy and larger sample sizes are warranted to examine the role of mindful eating in treating pediatric obesity.

Relationship between 25(OH)D levels and circulating lipids in African American adolescents.

BACKGROUND: Vitamin D deficiency is commonly seen among African American adolescents. Lipid levels during childhood are excellent predictors of adult dyslipidemia and atherosclerosis. There is a paucity of data on the relationship between 25 hydroxy vitamin D [25(OH)D] levels and lipids among African American adolescents. The objective of this study was to determine if there is an association between 25(OH)D levels and circulating lipids in African American adolescents residing in midwestern United States. METHODS: African American adolescents residing in Rochester, MN (latitude 44°N), USA, underwent measurements of 25(OH)D and lipids following overnight fast. Pearson's correlation test, linear regression model and scatter plots were used to explore the association between 25(OH)D levels and lipids. RESULTS: 25(OH)D levels <30 ng/mL were seen in 21/24 (87%) of the subjects. 25(OH)D levels were inversely correlated with total cholesterol (r=-0.42; p=0.040) and with non-high-density lipoprotein (non-HDL) cholesterol (r=-0.42; p=0.040 ). These associations remained statistically significant after adjustment for age, gender and adiposity. In the multivariate linear regression model, and after adjusting for BMI Z-score, each 1 ng/mL increase in 25(OH)D was associated with a decrease in total cholesterol of 1.38 mg/dL (95% CI: -2.63, -0.14, p=0.030) and with a decrease in non-HDL cholesterol of 1.14 mg/dL (95% CI: -2.09, -0.18, p=0.020). CONCLUSIONS: 25(OH)D levels were inversely correlated with total cholesterol and non-HDL cholesterol levels in African American adolescents residing in midwestern United States. Further studies with larger sample sizes are needed to determine if low vitamin D status in African American adolescents is a potential modifiable risk factor for cardiovascular disease.
