Is branding food promoting obesity? An investigation on children in San Luis Potosí

This study aims at assessing children's awareness towards branded food products in central Mexico. One-hundred and twenty children, aged 3-10 years and balanced by gender, were recruited in San Luis Potosí. Kids' heights and weights were measured in order to calculate their BMI. A cross-sectional questionnaire was administered to children's parents in order to gain socio-demographic information. Children's brand awareness was assessed using the IBAI (International Brand Awareness Inventory). Basic exploratory analyses were performed for samples' general characteristics, and ANOVA was adopted for investigating differences between the IBAI tasks. Results demonstrated that 50% of kids correctly associated the logo to the respective brand in more than 70% of the cases. About half of the sample recalled the right name of the food type in 50% of the cases. 50% of kids recognized the brand name in less than 20% of cases. Older children (7-10 y) showed a higher brand awareness when compared to younger ones (3-6 y). Children demonstrated a consistent knowledge of famous fast-food and snack products. Prevention through informative campaigns should make parents more aware of the TV contents, their kids are exposed to(AU)

Este estudio tiene como objetivo evaluar la conciencia de los niños hacia los productos alimenticios de marca en México. Ciento veinte niños, de entre 3-10 años en grupos equitativos por sexos, fueron reclutados en San Luis Potosí. Se midieron la talla y los pesos de los niños con el fin de calcular sus IMC. A los padres de los niños se les entrego un cuestionario transversal a fines de obtener información socio-demográfica. El conocimiento de la marca de los niños se evaluó, mediante el uso del IBAI (Inventario Internacional de conocimiento de la marca). Se realizó un análisis exploratorio de base para obtener las características generales de la muestra y se adoptó un anova para investigar las diferencias entre las tareas ibai . Los resultados demostraron que el 50% de los niños había asociado correctamente el logotipo de la marca respectiva en más del 70% de los casos. Aproximadamente la mitad de la muestra recordaba el nombre correcto de marca de alimentos en el 50% de los casos. 50% de los niños reconocía el nombre de la marca en menos del 20% de los casos. Los niños mayores (7-10 años) mostraron una conciencia de marca más alta si se compara con los más jóvenes (3-6 años). Los niños demostraron consistentemente tener conocimiento de los productos de comida rápida y bocadillos más conocidos. La prevención a través de campañas informativas debería conscientizar a los padres sobre los contenidos de televisión a los que que sus hijos están expuestos(AU)

Changes in ultraviolet absorbance and hence in protective efficacy against lipid peroxidation of organic sunscreens after UVA irradiation.

Owing to the spectral distribution of solar UV, the UVA component of sunlight is now believed to be the main cause of photoaging and photocarcinogenesis and is much more effective than UVB in inducing peroxidative damage. Consequently, most skin care cosmetic products now include UVA filters in their formulations along with UVB filters. These modern sunscreens should provide and maintain their initial absorbance, hence protection, throughout the entire period of exposure to sunlight. However, not all UVA and UVB filters are sufficiently photostable. In this study, we examine the correlation between the photochemical degradation of sunscreen agents under UVA irradiation, with particular reference to the UVA-absorber 4-tert-butyl-4'-methoxydibenzoylmethane, alone and in combination with other organic UV filters (2-ethylhexyl 4 methoxycinnamate and 2-ethylhexyl 2-cyano-3,3-diphenylacrylate) and their ability to prevent UVA-induced lipid peroxidation. Since antioxidants are also added to formulations to deactivate free radicals generated during UVA exposure, vitamin E and the synthetic antioxidant, bis(2,2,6,6-tetramethyl-1-oxyl-piperidine-4-yl)sebacate, a nitroxide derivative, were also included in this study. By using simple in vitro tests, the results show that a decrease in spectral absorbance of the UV filters correlates in most cases with increased UVA-induced lipid peroxidation; this depends on the specific UV absorber analysed and also on whether they are alone or in combination. Furthermore, the combined presence or absence of antioxidants has a profound effect on this oxidative event. In particular, the nitroxide appears to be a more efficient photo-antioxidant than vitamin E. Similar experiments were also performed under natural sunlight and the results obtained did not differ substantially from those performed under UVA. The results presented and discussed in this work may help in understanding the effects of UVA/UVB absorbers and antioxidants upon the level of UV-induced ROS generated under UVA exposure and in natural sunlight which could be relevant for improving the photoprotection and efficacy of skin care cosmetic formulations.

Behavioral and emotional response of Japanese macaque (Macaca fuscata) mothers after their offspring receive an aggression.

The authors of this study investigated the behavioral and emotional response of female Japanese macaques (Macaca fuscata) to an aggression received by their offspring to evaluate the existence of cognitive empathic responses in a naturalistic setting. After their offspring received an aggression, mothers did not direct increased affiliative contacts to them. The factors likely to affect the degree of distress in the offspring or the perceived risk for the mother failed to appropriately modulate maternal behavior. Finally, mothers did not increase their frequency of scratching (a behavioral indicator of anxiety) after their offspring had received an aggression. The results suggest Japanese macaque mothers may be unable to understand their offspring's need for distress alleviation after the receipt of aggression.
