Socioeconomic status (SES) influences all the determinants of health, conditioning health throughout life. The aim of the present study was to explore the relationship between socioeconomic status and obesity in adolescence through an analysis of the patterns of contact between peers as a function of this parameter. A cross-sectional study was performed, analyzing a sample of 235 students aged 14 to 18 and 11 class networks. Social network analysis was used to analyze structural variables of centrality from a sociocentric perspective. We found that adolescents with a medium-low SES presented a two-fold higher probability of being overweight, but we did not detect any differences in the configuration of their social networks when compared with those of normal-weight adolescents. However, we did find significant differences in the formation of networks according to SES in the overall sample and disaggregated by gender, whereby adolescents with a high SES in general presented a higher capacity to form wider social networks. Elucidating the relationship between SES and overweight and its influence on social network formation can contribute to the design of preventative strategies against overweight and obesity in adolescents, since their social environment can provide them with several resources to combat excess weight.

The physical fitness of women with fibromyalgia, as determined by the Six-Minute Walk Test and the Fibromyalgia Impact Questionnaire, has no direct relation with quality of life as the patients perceive it.

The objective of this study was to assess the long- and short-term effects of a multimodal program, specifically designed to be carried out by fibromyalgia syndrome (FMS) patients themselves, after a 12-week period of learning. Thirty female FMS patients volunteered for the study. The learning phase consisted on twelve weekly sessions of an hour, combining muscular resistance and flexibility exercises with techniques of breathing and relaxing, plus a half-hour incentive physiotherapy session. Flexibility, illness impact and pain were assessed at the beginning of the study, at the end of the learning phase and six months afterwards (follow-up). Twenty-one patients completed the programme. At the end of the learning phase, the improvement in the patients' physical condition was significant, as was the impact of the illness. Thirty-three percent of the patients continued training during the follow-up period and kept up the improvements achieved. The self-controlled multimodal programme was efficient in improving flexibility and reducing the impact of the illness in women fibromyalgia patients. However, adherence was poor when patients had to exercise on their own.

Neuromuscular electrostimulation (NMES) has been used mainly as a method to promote muscle strength, but its effects on improving blood flow are less well known. The aim of this study is to deepen the knowledge about the local and contralateral effects of the application of symmetric biphasic square currents on skin temperature (Tsk). An experimental pilot study was developed with a single study group consisting of 45 healthy subjects. Thermographic evaluations were recorded following the application of NMES to the anterior region of the thigh. The results showed an increase in the maximal Tsk of 0.67% in the anterior region of the thigh where the NMES was applied (p < 0.001) and an increase of 0.54% (p < 0.01) due to cross-education effects, which was higher when the NMES was applied on the dominant side (0.79%; p < 0.01). The duration of the effect was 20 min in the dominant leg and 10 min in the nondominant one. The application of a symmetrical biphasic current (8 Hz and 400 μs) creates an increase in the maximal Tsk at the local level. A temperature cross-education effect is produced, which is greater when the NMES is applied on the dominant side. This could be a useful noninvasive measurement tool in NMES treatments.

The caregivers of dependent persons should benefit from social–health interventions that empower them. Physiotherapists can play an important role as facilitators of self-care learning by boosting the mind–body interaction. The aim of this study was to analyse the efficacy of a physiotherapeutic intervention centered on the promotion of self-care within a sample of caregivers, members of four Spanish Associations of Relative of Alzheimer's and other dementias. To fulfill the study goal, a pre-experimental study was developed with two different groups. Group 1 participated in four training sessions based exclusively on the communication of information and which addressed, among other aspects, the most frequent health problems in caregivers and the powerful role of self-care to face such problems. Group 2 received the same theoretical information as group 1, followed by 10 sessions of practical training in several concrete strategies of body–mind self-care. The results obtained support the usefulness of combining theoretical and practical training in mind–body strategies (relaxation, self-massage and stretching), as such combination managed to favor their implication to self-care and certain dimensions of psychological well-being, while attenuating the burden. Conversely, training based solely on theoretical approaches was not beneficial. Besides evidencing the usefulness of combining passive and active methodologies to favor self-care, the data provided calls for greater consideration of aspects close to philosophical perspectives like personal growth.
