RESUMO
BACKGROUND: The combination of higher stress and higher obesity rates suggests that Latino youth in the United States may be a population at particular risk for obesity-related adverse health outcomes. The objective of this article is to describe the feasibility, acceptability, and quantitative stress-related outcomes of a 6-week pilot lifestyle intervention using guided imagery (GI) council in order to reduce risk factors for obesity-related disease. METHODS: Seventeen urban, adolescents (12 females/5 males, 16 Latino, age 17 ± 1 years, grades 9-12, body mass index 22 ± 4) participated in the 6-week, after-school pilot intervention. The intervention consisted of three, 75-minute after-school sessions delivered weekly for 6 weeks. The 3 weekly sessions included 1 session each of nutrition education, physical activity education and practice, and GI delivered in council, a facilitated group process based on indigenous practices. Feasibility and acceptability were assessed by attendance and qualitative exit interview. Stress outcomes included salivary cortisol and perceived stress. RESULTS: The pilot intervention was found to be feasible to deliver in an after-school setting. The GI and council group format were well liked. A 31% reduction in salivary cortisol was observed following the stress-reduction GI sessions. Diurnal cortisol patterns did not change across the intervention, but change in perceived stress was correlated with change in cortisol awakening response. CONCLUSIONS: The intervention was feasible to deliver and highly acceptable. Acute reduction in salivary cortisol was seen following group GI, while no change was seen in daily cortisol patterns. These results support the development of a full 12-week intervention using GI council to reduce obesity-related disease risk.
RESUMO
BACKGROUND: The transition of young adults with type 1 diabetes (T1D) from pediatric to adult care is challenging and frequently accompanied by worsening of diabetes-related health. To date, there are no reports which prospectively assess the effects of theory-based psycho-behavioral interventions during the transition period neither on glycemic control nor on psychosocial factors that contribute to poor glycemic control. Therefore, the overall aim of this study was to develop and pilot test an integrative group intervention based on the underlying principles of self-determination theory (SDT), in young adults with T1D. METHODS: Fifty-one young adults with T1D participated in an education and case management-based transition program, of which 9 took part in the Diabetes Empowerment Council (DEC), a 12-week holistic, multimodality facilitated group intervention consisting of "council" process based on indigenous community practices, stress-reduction guided imagery, narrative medicine modalities, simple ritual, and other integrative modalities. Feasibility, acceptability, potential mechanism of effects, and bio-behavioral outcomes were determined using mixed qualitative and quantitative methods. RESULTS: The intervention was highly acceptable to participants, though presented significant feasibility challenges. Participants in DEC showed significant reductions in perceived stress and depression, and increases in general well-being relative to other control participants. Reduction in perceived stress, independent of intervention group, was associated with reductions in hemoglobin A1C. A theoretical model explaining the effects of the intervention included the promotion of relatedness and autonomy support, 2 important aspects of SDT. CONCLUSIONS: The DEC is a promising group intervention for young adults with T1D going through transition to adult care. Future investigations will be necessary to resolve feasibility issues, optimize the multimodality intervention, determine full intervention effects, and fully test the role of the underlying theoretical model of action.ClinicalTrials.gov Registration Number NCT02807155; Registration date: June 15, 2016 (retrospectively registered).
