RESUMEN
Resumen El aumento demográfico de adultos mayores se está presentando acompañado de condiciones socioeconómicas y de salud desfavorables, que afectan su calidad de vida. Esta situación puede paliarse a través del marco del envejecimiento activo, el cual aporta lineamientos alternativos que pueden resultar eficaces para contrarrestarlos. La Organización Mundial de la Salud establece que el envejecimiento activo tiene seis Determinantes Sociales de la Salud (DSS) que han sido abordados desde diferentes áreas por la comunidad científica. El objetivo del presente trabajo fue identificar y caracterizar el tipo de estudios enfocados a la calidad de vida, desde el envejecimiento activo, y clasificarlos de acuerdo con los DSS. Se revisaron las bases de datos Ebscohost, Scopus, Oxford, Redalyc y Sage Journals. Los descriptores utilizados fueron "envejecimiento activo" y "calidad de vida", en inglés y español. La búsqueda del mapeo sistemático comprendió enero 2015 a marzo 2022. Se localizaron 91 artículos en los que se evaluó la calidad de vida, desde la perspectiva del envejecimiento activo y la mayoría (81.3 %) fueron estudios transversales. Se identificaron 3 intervenciones psicológicas, con evaluación antes y después de las sesiones, abordando los DSS relacionados con los factores personales, como salud psicológica, percepción positiva con la actividad física y función cognitiva. Así mismo, los factores conductuales, como estilos de vida para la prevención de riesgo de caídas y mejora de la vida en general, que podrían condicionar la calidad de vida. El principal alcance temático de los estudios fue la vinculación existente entre la calidad de vida y los DSS relacionados con los factores personales y con el entorno social. Se requieren más estudios interdisciplinarios que ayuden a generar políticas públicas que impacten favorablemente en este sector poblacional.
Abstract The demographic increase of elderly people is taking place along with unfavorable socioeconomic and health conditions, which affect their quality of life. This situation can be alleviated through an active aging framework, which provides alternative guidelines that can be effective in counteracting them. The World Health Organization establishes that active aging has six Social Determinants of Health (SDH) that have been approached from different areas by the scientific community. The objective of this work was to identify and characterize the type of studies focused on quality of life, from active aging, and classify them according to the SDH. Ebscohost, Scopus, Oxford, Redalyc and Sage Journals databases were reviewed. The descriptors used were "active aging" and "quality of life", in English and Spanish. The systematic mapping search comprised from January 2015 to March 2022. 91 articles were located where quality of life was evaluated from the perspective of active aging and the majority (81.3 %) were cross-sectional studies. Three psychological interventions were identified, with an evaluation before and after the sessions, comprising the SDH related to personal factors, such as psychological health, positive perception with physical activity and cognitive function. Likewise, behavioral factors such as lifestyles for the prevention of risk of falls and general life improvement which could condition the quality of life. The main thematic scope of the analyzed studies was the existing relationship between quality of life and the SDH related to personal factors and the social environment. Further interdisciplinary studies are required to contribute to the creation of public policy that impacts favorably this sector of the population.
RESUMEN
OBJECTIVE: To validate a Spanish-language questionnaire on adolescent eating behavior based on Social Cognitive Theory. DESIGN: The validity (reliability and construct validity) of a self-administered questionnaire containing 28 questions with Likert scale-type response options was evaluated. SETTING: School located in Tonala, Jalisco, Mexico (a peri-urban area) with approximately 1,400 students enrolled. PARTICIPANTS: One hundred fifty-two adolescents enrolled in the second year of a middle school in Tonalá, Jalisco, Mexico (mean age, 13.7 years; SD, 0.5 years; 64% female). The retest was completed by 70 adolescents chosen at random. OUTCOME MEASURES AND ANALYSIS: The questionnaire's reliability was measured through internal consistency (Cronbach α) and reproducibility (intraclass correlation coefficient [ICC]). Construct validity was assessed using exploratory factor analysis. RESULTS: Five questions were eliminated from the questionnaire because of a lack of temporal stability (ICC ≤0.4). The exploratory factor analysis was satisfactory for 3 factors (41.89% of variance): environmental facilitators and social support, self-efficacy and self-regulation, and outcome expectations and outcome expectations value. The questionnaire had good internal consistency (αâ¯=â¯0.824) and excellent temporal stability (ICCâ¯=â¯0.849). CONCLUSIONS AND IMPLICATIONS: The results substantiate the reliability and construct validity of this questionnaire. The questionnaire has the potential to use the assessment of Social Cognitive Theory constructs in clinical practice or in nutrition interventions aimed at modifying the eating habits of Spanish-speaking adolescents.
