ABSTRACT
Mexican Afro-descendant is a population poorly studied in many aspects, between them the infectious diseases that they suffer. This population is mainly found in the country's Pacific (Oaxaca and Guerrero states) and Atlantic (Veracruz) coast. In these regions, a diversity of triatomine vectors of the Chagas disease is found. Also, all the genotypes of Trypanosoma cruzi DTUs have been reported. That is why the present study aimed to study the presence of antibodies against T. cruzi and cardiac pathology associated with the Chagas disease in the Mexican Afro-descendant population of Guerrero and Oaxaca. ELISA, Western blot, and recombinant antigen's ELISA were used to evaluate the seropositivity of these communities. Furthermore, an electrocardiographic study and evaluation of risk factors associated with T. cruzi infection in the Oaxaca and Guerrero populations were conducted. 26.77% of the analyzed population was positive for two serological tests. These percentages are higher than the previously reported for the mestizo population in similar studies. Electrocardiographic results showed cardiac disorder associated with the Chagas disease in the population. Also, risk factors were identified associated with the men's activities in the outdoor working areas.
ABSTRACT
El objetivo de este estudio fue comparar características generales y de atención en salud entre menores y sus madres migrantes y no migrantes en indígenas Tarahumaras, en Chihuahua, México. Así mismo, se evaluó la asociación entre el riesgo de retraso en neurodesarrollo en niños y las prácticas de estimulación oportuna. Niños y niñas de entre 12 a 48 meses de edad fueron estudiados en dos grupos: 1) menores de madres migrantes ubicados en asentamientos urbanos en la ciudad de Chihuahua y 2) menores de madres no migrantes residentes en sus localidades de origen. La prevalencia de riesgo de retraso del neurodesarrollo moderado y grave (RNMG) fue mayor en menores de madres migrantes versus no migrantes (75.6%, IC95% [69.5, 80.8] vs 59.8%, [51.4, 67.7], p = .003). La proporción de niños(as) que recibieron una estimulación oportuna favorable (EOF) en casa fue mayor en los menores de madres no migrantes (p < .001). La migración de las madres indígenas hacia asentamientos urbanos estuvo asociada al RNMG en sus hijos(as) (p = .03), así como las prácticas insuficientes de estimulación oportuna (p = .03). La asistencia consistente a sesiones de estimulación temprana del programa de Educación Inicial fue mayor en niños(as) de madres no migrantes (p = .01); y la no asistencia fue predictor del RNMG (p = .02).(AU)
This study aimed to compare the general and health care charac-teristics of young children of migrant and non-migrant mothers from in-digenous Tarahumara communities in Chihuahua, Mexico, and to evaluate the association between child risk for neurodevelopment delay with paren-tal practices of early childhood stimulation. Male and female children aged 12 to 48 months were studied in two groups: 1) children of migrant moth-ers residing in urban settlements and 2) children of non-migrant mothers residing in their native rural localities. Prevalence of the risk of moderate to severe neurodevelopment delay (MSND) was greater in children of mi-grant mothers as compared to non-migrant mothers (75.6%, CI95% [69.5, 80.8] vs.59.8%, [51.4, 67.7], p = .003). The proportion of children who re-ceived adequate and favorable early stimulation (FTES) at home was great-er in children of non-migrant mothers (p < .001). The migration of indige-nous mothers to urban settlements was associated with child MSND (p = .03), as well as to insufficient early stimulation practices (p = .03). Con-sistent attendance at early childhood stimulation sessions through the Ini-tial Education program was greater in children of non-migrant mothers (p = .01), and non-attendance predicted child MSND (p = .02).(AU)
