          Abstract

          Abstract Objectives: the current study evaluated the orthorexic tendencies of social media users and the factors affecting these tendencies. Methods: a total of 2526 adult participants (696 male and 1830 female, 28.4 ± 10.3 years) completed a questionnaire that includes personal information, the Orthorexia Nervosa Scale (ORTO-11), the Social Media and Eating Behavior Scale (SMEB), and the International Physical Activity Questionnaire Short Form (IPAQ). Body mass index (BMI) was calculated from the reported weight and height of the participants. Independent-sample t-tests or chi-square tests were computed to evaluate various information of the participants according to the ON tendency. A binary logistic regression analysis was used to identify risk factors. Results: according to ORTO-11, 56.1 % of the participants had a tendency to ON, and the trend to ON increased with age and BMI (p < 0.05). People without ON tendency spent more time (172.2 ± 119.9 min/day) on social media. Participants who followed webpages with healthy nutrition and sport-exercise recommendations had an increased ON risk when compared to those who did not follow those pages (p < 0.05). In addition, although there was a significant difference between participants in physical activity level according to the ON tendency, this relationship was not significant in the regression model (p > 0.05). Conclusion: this study indicates that increasing social media usage, especially web pages that include health and nutrition recommendations, may boost the tendency to ON. Thus, raising awareness of social media may be beneficial to people who have a tendency to ON.

          Resumen Objetivos: el presente estudio evaluó las tendencias ortoréxicas de los usuarios de las redes sociales y los factores que afectan a estas tendencias. Métodos: un total de 2526 participantes adultos (696 hombres y 1830 mujeres, 28,4 ± 10,3 años de edad) completaron un cuestionario que incluye información personal, la escala de ortorexia nerviosa (ORTO-11), la escala de redes sociales y conducta alimentaria (SMEB) y el cuestionario internacional de actividad física en formato corto (IPAQ). El índice de masa corporal (IMC) se calculó a partir del peso y la estatura declarados por los participantes. Se realizaron pruebas t o pruebas del chi cuadrado de muestras independientes para evaluar la diversa información de los participantes según la tendencia a la ortorexia nerviosa. Se utilizó un análisis de regresión logística binaria para identificar los factores de riesgo. Resultados: según el ORTO-11, el 56,1 % de los participantes tenían tendencia a la ortorexia nerviosa y esta tendencia aumentaba con la edad y el IMC (p < 0,05). Las personas sin tendencia a la ortorexia nerviosa dedicaban más tiempo (172,2 ± 119,9 min/día) a las redes sociales. Los participantes que seguían páginas web con recomendaciones sobre alimentación saludable y deporte/ejercicios tenían un mayor riesgo de ortorexia nerviosa que los que no seguían esas páginas (p < 0,05). Además, aunque había una diferencia significativa entre los niveles de actividad física de los participantes según la tendencia a la ortorexia nerviosa, esta relación no era significativa en el modelo de regresión (p > 0,05). Conclusión: este estudio indica que el incremento del uso de las redes sociales, especialmente de las páginas web que incluyen recomendaciones sobre salud y alimentación, podría favorecer la tendencia a la ortorexia nerviosa. Por lo tanto, concienciar a las personas con tendencia a la ortorexia nerviosa sobre las redes sociales puede tener un efecto beneficioso.

          Validity of the international physical activity questionnaire short form (IPAQ-SF): A systematic review

          Background The International Physical Activity Questionnaire - Short Form (IPAQ-SF) has been recommended as a cost-effective method to assess physical activity. Several studies validating the IPAQ-SF have been conducted with differing results, but no systematic review of these studies has been reported. Methods The keywords "IPAQ", "validation", and "validity" were searched in PubMed and Scopus. Studies published in English that validated the IPAQ-SF against an objective physical activity measuring device, doubly labeled water, or an objective fitness measure were included. Results Twenty-three validation studies were included in this review. There was a great deal of variability in the methods used across studies, but the results were largely similar. Correlations between the total physical activity level measured by the IPAQ-SF and objective standards ranged from 0.09 to 0.39; none reached the minimal acceptable standard in the literature (0.50 for objective activity measuring devices, 0.40 for fitness measures). Correlations between sections of the IPAQ-SF for vigorous activity or moderate activity level/walking and an objective standard showed even greater variability (-0.18 to 0.76), yet several reached the minimal acceptable standard. Only six studies provided comparisons between physical activity levels derived from the IPAQ-SF and those obtained from objective criterion. In most studies the IPAQ-SF overestimated physical activity level by 36 to 173 percent; one study underestimated by 28 percent. Conclusions The correlation between the IPAQ-SF and objective measures of activity or fitness in the large majority of studies was lower than the acceptable standard. Furthermore, the IPAQ-SF typically overestimated physical activity as measured by objective criterion by an average of 84 percent. Hence, the evidence to support the use of the IPAQ-SF as an indicator of relative or absolute physical activity is weak.

              Instagram #instasad?: exploring associations among instagram use, depressive symptoms, negative social comparison, and strangers followed.

              As the use and influence of social networking continues to grow, researchers have begun to explore its consequences for psychological well-being. Some research suggests that Facebook use can have negative consequences for well-being. Instagram, a photo-sharing social network created in 2010, has particular characteristics that may make users susceptible to negative consequences. This study tested a theoretically grounded moderated meditation model of the association between Instagram use and depressive symptoms through the mechanism of negative social comparison, and moderation by amount of strangers one follows. One hundred and seventeen 18-29 year olds completed online questionnaires containing demographics, frequency of Instagram use, amount of strangers followed on Instagram, the Center for Epidemiological Resources Scale for Depression, and the Social Comparison Rating Scale. Instagram use was marginally positively associated with depressive symptoms, and positive social comparison was significantly negatively associated with depressive symptoms. Amount of strangers followed moderated the associations of Instagram use with social comparison (significantly) and depressive symptoms (marginally), and further significantly moderated the indirect association of Instagram use with depressive symptoms through social comparison. Findings generally suggest that more frequent Instagram use has negative associations for people who follow more strangers, but positive associations for people who follow fewer strangers, with social comparison and depressive symptoms. Implications of negative associations of social networking for people who follow strangers and the need for more research on Instagram use given its increasing popularity are explored.
