Lifestyle mediates the relationship between self-esteem and health-related quality of life in Chilean schoolchildren

A healthy lifestyle, including food habits, physical activity (PA) and screen time (ST), is an important factor for well-being. The main purpose of this study was to analyze the association between lifestyle (i.e., PA, ST and food habits), self-esteem and health-related quality of life (HRQoL). A second objective was to determine the association between self-esteem with HRQoL, considering the mediating effect of lifestyle. A descriptive and cross-sectional study was performed, involving both girls (n = 282, 11.86 ± 0.82 years) and boys (n = 352, 12.02 ± 0.87 years). Lifestyle, self-esteem, HRQoL and anthropometrics parameters were evaluated. The study reported that self-esteem (β; 0.04, P = 0.49) and PA (β; 1.15, P < 0.001) had positive association with HRQoL. By contrast,ST was linked in an inverse way to HRQoL (β; -1.82,, P < 0.001). According to the second objective, self-esteem had a significant association with HRQoL (total effect = 0.48, p < 0.01), and ST mediated this association negatively, instead, PA and food habits positively mediated this association. In conclusion, self-esteem presented association with HRQoL and lifestyle mediates this relationship positively (PA, MD adherence) and negatively (ST). Therefore, promoting healthy lifestyle among children should be a target of community- and school-based interventions to promote well-being.

Analysis of the performance of women with fibromyalgia in the six-minute walk test and its relation with health and quality of life

Fibromyalgia (FM) is a chronic syndrome characterized by widespread musculoskeletal pain that causes a significant reduction in functional capacity, affecting thus health and quality of life (QOL).

AIM

The aim of the present study was to evaluate the performance of FM patients in the 6-Minute Walk Test (6MWT) and its relation with health and QOL.

METHODS

Thirty-six FM patients (all women), differentiated by degree of severity of disease, and 14 healthy women were evaluated. Distance walked in the 6MWT, cardiorespiratory responses, heart rate responses, kinematic parameters of gait, the results of the Fibromyalgia Impact Questionnaire (FIQ), and the results of the Short-Form Healthy Survey (SF-36) were analyzed.

RESULTS

Women with FM covered a shorter distance in the 6MWT, had a lower cardiorespiratory response, and had lower spatio-temporal parameters of gait than healthy women. No correlation was found in FM patients between the total FIQ score and the distance walked in the 6MWT.

CONCLUSION

The analysis of performance parameters in the 6MWT may be an element of clinical relevance in FM patients.
