[Mortalidad por enfermedad de Alzheimer en México de 1980 a 2014].

BACKGROUND: Dementias are rarely considered to be a main cause of death; therefore there are only few studies on Alzheimer's mortality covering long periods. OBJECTIVE: To describe mortality from Alzheimer's disease in México for the period from 1980 to 2014. METHOD: Cross-sectional study where, with official mortality data in Mexico according to codes 331.0 and G30, respectively, of the 9th and 10th revisions of the International Statistical Classification of Diseases and Related Health Problems, crude and standardized Alzheimer's disease mortality rates were obtained, both nationally and by states. RESULTS: From almost being inexistent, deaths from Alzheimer's disease went to a rate of 65.12 per 1000 females and 43.66 per 1000 males in the 2010-2014 five-year period. Throughout the study period, the age group with highest mortality rates for this cause were those older than 80 years, with 0.29 per 100,000 population in 1980-1984 and 55.02 in 100,000 in the 2010-2014 period. The region with the highest mortality was the northwest, with rates higher than 2.28 per 100,000 population. CONCLUSIONS: Mortality from Alzheimer's disease is a public health problem in Mexico with a growing trend, especially among women and older adults. Early diagnostic measures and opportune treatment are required in primary care in order to reduce this problem.

INTRODUCCIÓN: Raramente se considera a las demencias como causa principal de muerte, por consiguiente existen pocos estudios sobre la mortalidad por Alzheimer a través de largos periodos. OBJETIVO: Describir la mortalidad por enfermedad de Alzheimer en México durante el periodo 1980-2014. MÉTODO: Estudio transversal en el que, con datos oficiales de mortalidad en México según los códigos 331.0 y G30 de la novena y décima revisiones de la Clasificación Estadística Internacional de Enfermedades y Problemas Relacionados con la Salud, se obtuvieron tasas crudas y estandarizadas de mortalidad por enfermedad de Alzheimer, nacional y por entidad federativa. RESULTADOS: De ser casi inexistentes, en el quinquenio 2010-2014 se registraron tasas de 65.12 y 43.66 muertes por enfermedad de Alzheimer por cada 1000 mujeres y 1000 hombres, respectivamente. En todo el periodo estudiado, el grupo etario con las mayores tasas de mortalidad por esta causa fue el de mayores de 80 años, con 0.29 en 100 000 habitantes durante 1980-1984 y 55.02 durante 2010-2014. La región con mayor mortalidad fue la noroeste, con tasas mayores a 2.28 en 100 000 habitantes. CONCLUSIONES: La mortalidad por enfermedad de Alzheimer es un problema de salud pública en México con tendencia creciente, especialmente entre mujeres y adultos mayores. Se requieren medidas diagnósticas precoces y tratamiento oportuno en primer nivel para aminorar este problema.

[Differentiated consumption of macronutrients according to sex and age in higher education students]. / Consumo diferenciado de macronutrientes según sexo y edad en estudiantes de educación superior.

OBJECTIVE: To analyze the intake of macronutrients and its relationship with age and sex in higher education students. MATERIALS AND METHODS: A cross-sectional study was carried out with 218 higher education students, aged between 18 and 30 years. A validated and reliable instrument was used to measure macronutrient consumption. RESULTS: Regarding the intake of macronutrients, a statistical difference by sex was observed in favor of men (p>0.05), except for the consumption of proteins in students older than 25 years. In the group under 20 years of age, men showed better protein intake. Finally, in students between 20 and 25 years, the consumption of macronutrients is similar among men and women. DISCUSSION: The results show that the percentage of consumption with respect to ideal value of the estimated requirement for light activity according to FAO/WHO/UN 2004 is below the recommendations, with a macronutrient consumption deficit that ranges between 20% and 60%.

OBJETIVO: Analizar la ingesta de macronutrientes y su relación con la edad y sexo en estudiantes de educación superior. MÉTODOS: Se realizó un estudio transversal conformado con 218 estudiantes de educación superior de 18 a 30 años. Se utilizó un instrumento validado y confiable, para medir el consumo de macronutrientes. RESULTADOS: Respecto a la ingesta de consumo de macronutrientes se observa que hay diferencia estadística por sexo, a favor de los hombres (p>0,05), excepto en el consumo de proteínas en los estudiantes mayores de 25 años. En el grupo etario menor a 20 años, los hombres tienen un mejor consumo de proteínas. En estudiantes de 20 a 25 años el consumo de macronutrientes es parecido entre hombres y mujeres. DISCUSIÓN: Los resultados evidencian que el porcentaje de consumo respecto del valor ideal de requerimiento estimado para actividad ligera según FAO/OMS/ONU 2004, está por debajo, con un déficit de consumo de macronutrientes que oscila entre el 20% y el 60%.

A search for a safer bucket to prevent children drowning at home.

BACKGROUND: Unintentional drowning is the leading cause of death for children younger than 5 years old. A bucket is one of the most common water container in which children can drown. The objective of this work was to evaluate the base diameter of a bucket and the necessary force to shed it. METHODS: This was an experimental study. We used six galvanized buckets of different diameters. Each selected bucket was pulled using a pulley with other buckets full of water until the water spilled out. The statistical analysis was done by linear regression with p less than 0.05 as statistically significant. RESULTS: This research shows a direct relation between the wide base diameter (in a bucket 23 cm high, 25 cm rim, with a 20 cm water depth) and the strength required to spill the liquid contents (ß= 1.21; x= diameter of the base in centimeters; α= 14.59; r= 0.99 and p less than 0.001). CONCLUSIONS: We conclude that the bucket structure could determine the risk of child drowning. The risk could increase directly as its base width increases.
