RESUMO

BACKGROUND: Elder abuse (EA), depressive symptoms, and loneliness represent a growing risk to the health, well-being, and premature mortality of older adults. However, the role of loneliness in the relationship between EA and depressive symptoms has not yet been examined. AIMS: To investigate the associations between these constructs and to explore the possible mediating role of loneliness in the relationship between EA and depressive symptoms in a representative sample of older Mexican people. METHODS: A representative community-dwelling survey of older adults aged 60 and older was conducted in two cities in Mexico (Mexico City and Xalapa) in 2018-2019. Measurements of EA, loneliness, depressive symptoms, health, and sociodemographic data were collected. Regression and mediation models were tested to analyze the associations between these variables. RESULTS: The prevalence of EA was 16.3%, loneliness was 50%, and depressive symptoms were 25.5%. The odds ratio (OR) for the occurrence of depressive symptoms was 2.7 when the combined effects of EA and loneliness were considered. The proportion of the effect that could explain the mediating role of loneliness was 31%. CONCLUSION: To effectively reduce depressive symptoms in older individuals affected by emotional or psychological abuse and neglect, it is crucial to address both the mediating influence of loneliness and EA itself in therapeutic and preventive interventions.

RESUMO

Background: Being indigenous, being a woman, and living in poverty are social determinants that contribute to reduced access to healthcare, including reproductive health services. The COVID-19 pandemic might have exacerbated this lag. Objective: This study explored how the COVID-19 pandemic affected the contraceptive use of a group of indigenous Mexican women and adolescents in their community. Methods: Between June and December of 2021, 158 indigenous Mexican women who had experienced recurrent pregnancies were interviewed at two health centers in San Cristóbal de las Casas, Chiapas. Participants were either pregnant when they completed the questionnaire or had been pregnant during the COVID-19 pandemic. Women were asked about their contraceptive practices before and during the pandemic. The change in contraceptive practice was estimated using a logistic model. Results: The COVID-19 pandemic reduced contraceptive use by 50%. Among women who wanted contraception, 58% did not receive it. During the pandemic, 77% of previous contraceptive users reported difficulty obtaining contraception, and only 23% sought family planning assistance. Conclusion: During the COVID-19 pandemic, indigenous women in the studied community used fewer contraceptive methods and did not use intrauterine devices. Additionally, there was a decline in the percentage of women using contraceptives. These results highlight the impact on indigenous populations and the difficulties they could face in accessing reproductive health services during health emergencies.

RESUMO

Exclusive breastfeeding (EBF) is a cost-effective healthy behavior for the mother-child dyad. Globally, rates of EBF are low. Little research has been conducted on the joint role of modifiable and nonmodifiable variables in pregnant women's decision-making. The aim was to develop and test a model that used personal and sociodemographic factors to predict whether pregnant women who use public healthcare services plan to breastfeed. In a nonprobabilistic sample of 728 pregnant Mexican women, self-efficacy, the planned behavior theory constructs, and the intention to breastfeed (BFI) were measured. A total 60% of the sample was randomly chosen to develop a predictive multivariate logistic regression model. The model was validated in the remaining 40%. Women in the highest tertiles of attitudes and self-efficacy had fourfold increased chances of having a high BFI (OR 4.2, 95% CI [2.4, 7.4]). Working was associated with a decreased intention to exclusively breastfeed (OR 0.61, 95% CI [0.37, 0.98]). The model predicted BFI with a sensitivity of 38.3% and specificity of 82.2%. While personal variables predict the BFI, working decreases women's chances of breastfeeding. The results can be utilized to develop primary prevention strategies to help mothers who use public health services to breastfeed.

RESUMO

BACKGROUND: Patients with obesity have an increased risk for adverse COVID-19 outcomes. Body mass index (BMI) does not acknowledge the health burden associated this disease. The performance of the Edmonton Obesity Staging System (EOSS), a clinical classification tool that assesses obesity-related comorbidity, is compared with BMI, with respect to adverse COVID-19 outcomes. METHODS: 1071 patients were evaluated in 11 COVID-19 hospitals in Mexico. Patients were classified into EOSS stages. Adjusted risk factors for COVID-19 outcomes were calculated and survival analysis for mechanical ventilation and death was carried out according to EOSS stage and BMI category. RESULTS: The risk for intubation was higher in patients with EOSS stages 2 and 4 (HR 1.42, 95% CI 1.02-1.97 and 2.78, 95% CI 1.83-4.24), and in patients with BMI classes II and III (HR 1.71, 95% CI 1.06-2.74, and 2.62, 95% CI 1.65-4.17). Mortality rates were significantly lower in patients with EOSS stages 0 and 1 (HR 0.62, 95% CI 0.42-0.92) and higher in patients with BMI class III (HR 1.58, 95% CI 1.03-2.42). In patients with a BMI ≥ 25 kg/m2, the risk for intubation increased with progressive EOSS stages. Only individuals in BMI class III showed an increased risk for intubation (HR 2.24, 95% CI 1.50-3.34). Mortality risk was increased in EOSS stages 2 and 4 compared to EOSS 0 and 1, and in patients with BMI class II and III, compared to patients with overweight. CONCLUSIONS: EOSS was associated with adverse COVID-19 outcomes, and it distinguished risks beyond BMI. Patients with overweight and obesity in EOSS stages 0 and 1 had a lower risk than patients with normal weight. BMI does not adequately reflect adipose tissue-associated disease, it is not ideal for guiding chronic-disease management.

RESUMO

Childhood obesity is a major public health issue in Mexico. Schools are important settings to promote healthy eating habits. The aim of this study was to assess the extent of compliance with 2010 and 2014 Mexican school food guidelines in six public primary schools in Mexico City. The instruments for this study included semi-structured interviews (n=17) with principals, food vendors and members of the School Vending Committee, focus groups (n=10) with teachers and with parents, observation of six schools' environments, questionnaires applied to 325 schoolchildren from 4th, 5th and 6th grades and their parents, and a food analysis of items sold at school vending. Guidelines' compliance was assessed using all instruments accordingly. It was low in every dimension: 1) Acknowledgment of school food guidelines: None of the participants were familiar with the 2014 guidelines. 2) Healthy environment enhancement: Children lacked free access to safe drinking water. Children had up to five opportunities to eat during school day besides breakfast at home. Most children (67.7%) ate three to four times. 3) Operability of food and beverages sale and consumption: The only training provided to stakeholders was an annual session on hygiene to school food vendors. The majority of food and beverages offered at school vending exceeded energy, sodium, fat and added sugar content as established. Children sold energy-dense foods for school fundraising. Lack of dissemination and acknowledgment of the guidelines, defined roles and policy procedures, as well as training and capacity building for stakeholders impeded school food guidelines'proper implementation(AU)

La obesidad infantil es un problema de salud pública en México. La escuela es un lugar importante para promover hábitos saludables. El propósito del estudio fue evaluar el cumplimiento de los lineamientos escolares de alimentos de 2010 y 2014 en seis escuelas primarias públicas de la Ciudad de México. Los instrumentos incluyen entrevistas semi-estructuradas (n=17) con directores, vendedores de alimentos y miembros del Comité del Establecimiento de Consumo Escolar, grupos focales (n=10) con padres y con profesores, observación del entorno escolar, cuestionarios aplicados a 325 niños de 4º, 5º y 6º grado y a sus padres, y un análisis de los alimentos ofrecidos en la venta escolar. El cumplimiento de los lineamientos fue bajo en cada dimensión: 1) Conocimiento de los lineamientos: Ninguno de los participantes conocía los lineamientos de 2014. 2) Promoción de un ambiente saludable: No se tenía acceso libre a agua simple potable. Los niños tenían cinco oportunidades para comer durante la jornada escolar además del desayuno en casa. La mayoría de los niños (67.7%) comía de 3 a 4 veces. 3) Operatividad de la venta y consumo de alimentos y bebidas: La única capacitación fue una sesión anual de higiene a los vendedores. La mayoría de los alimentos y bebidas excedía los límites establecidos de calorías, sodio, grasa y azúcar añadida. Los niños vendían alimentos densos en energía para recaudar fondos. La falta de difusión de las guías, roles y políticas no definidos y una mínima capacitación obstaculizaron la implementación de los lineamientos(AU)

RESUMO

OBJECTIVE: To develop a new predictive equation for fat mass percentage (%FM) based on anthropometric measurements and to assess its ability to discriminate between obese and non-obese individuals. DESIGN: Cross-sectional study. SETTING: Mexican adults.ParticipantsAdults (n 275; 181 women) aged 20-63 years with BMI between 17·4 and 42·4 kg/m2. RESULTS: Thirty-seven per cent of our sample was obese using %FM measured by air-displacement plethysmography (BOD POD®; Life Measurement Instruments). The fat mass was computed from the difference between weight and fat-free mass (FFM). FFM was estimated using an equation obtained previously in the study from weight, height and sex of the individuals. The %FM estimated from the obtained FFM showed a sensitivity of 90·3 (95 % CI 86·8, 93·8) % and a specificity of 58·0 (95 % CI 52·1, 63·8) % in the diagnosis of obesity. Ninety-three per cent of participants with obesity and 65 % of participants without obesity were correctly classified. CONCLUSIONS: The anthropometry-based equation obtained in the present study could be used as a screening tool in clinical and epidemiological studies not only to estimate the %FM, but also to discriminate the obese condition in populations with similar characteristics to the participant sample.

RESUMO

Resumen La lactancia materna exclusiva (LME) es una de las conductas saludables con mayor valor protector para la salud del niño y de la madre. La autoeficacia es un predictor de diferentes conductas saludables. El objetivo de esta investigación fue diseñar y validar un instrumento para medir la autoeficacia para lactar en mujeres embarazadas. Se realizó un estudio instrumental con usuarias de dos centros de salud de primer nivel de atención, seleccionadas a través de un muestreo no probabilístico. Se excluyeron aquellas mujeres que fueran analfabetas o tuvieran alguna condición médica que contraindicara la LME. Se utilizaron análisis descriptivos, bivariados y multivariados para obtener las propiedades psicométricas del instrumento. Participaron 369 mujeres. A través de un análisis factorial exploratorio se obtuvo una estructura unidimensional de 15 reactivos que explicó el 83% de la varianza total del instrumento (alfa de Cronbach = .93). Además, la autoeficacia para lactar se asoció (p <.05) con la intención para lactar, la edad y la escolaridad. El instrumento de autoeficacia para lactar obtenido mostró propiedades psicométricas adecuadas por lo que puede ser útil para identificar a las mujeres que están en riesgo de no iniciar la LME desde el nacimiento de su hijo, además, parece ser el primer instrumento de autoeficacia para lactar en México.

Abstract Exclusive breastfeeding (EB) is a health behavior with a greatest health protective value for children and mothers. Self-efficacy is a predictor of different health behaviors. The objective of this research was to design and validate an instrument to measure self-efficacy to breastfeed in pregnant women. An instrumental study was conducted with users of two primary health care centers, selected through a non-probabilistic sampling. Those women who were illiterate or had a medical condition that contraindicated EB were excluded. Descriptive, bivariate and multivariate analysis were used to obtain the psychometric properties of the instrument. 369 women participated. An exploratory factorial analysis resulted in a 15 items unidimensional structure that explained 83% of the total variance of the scale (Cronbach's alpha = .93). In addition, self-efficacy for breastfeeding was associated (p<.05) with intention to breastfeed, age and scholarship. The breastfeeding self-efficacy scale obtained showed adequate psychometric properties. So, it can be useful to identify women who may be at risk of not initiate breastfeeding from birth, as well as, it seems to be the first breastfeeding self-efficacy scale in Mexico.

RESUMO

[ABSTRACT]. Objective. To estimate the association between stature in Mexican adults and some sociodemographic factors. Methods. We studied a sample of 30 970 subjects, using anthropometric data from the 2012 National Health and Nutrition Survey (ENSANUT 2012). The first quartile was used as the cutoff to define short stature. We analyzed differences among stature strata for sociodemographic variables by using the Kruskal-Wallis test. We estimated odds ratios to measure the association between stature and sociodemographic variables, controlling for potential confounders. Results. Persons from the southern region of the country were some three times as likely to be of short stature than were subjects in the northern region. The stature difference between the Mexican states with the highest and the lowest average stature was larger than the average difference in stature between Mexico and the United States of America. Adults who had had less than six years of schooling presented the highest prevalence of short stature, regardless of sex, region of the country, place of residence (rural or urban), or the proportion of indigenous language speakers in a state. In addition, the stratum with the highest marginalization (percentage of the population lacking education and services, with a low income, and living in a small community) showed the highest prevalence of short stature. Conclusion. In Mexico, adults who are of short stature have unequal living conditions when compared to those of average or high stature, and this could drive increases in health inequity.

Sobre la base de datos antropométricos de la Encuesta Nacional de Salud y Nutrición de 2012 (ENSANUT 2012), estudiamos una muestra de 30 970 sujetos. Para definir la estatura baja, el umbral se estableció en el primer cuartil. Analizamos las diferencias entre los distintos estratos de estatura en relación con variables sociodemográficas utilizando la prueba de Kruskal-Wallis. Calculamos las razones de posibilidades para medir la asociación entre la estatura y las variables sociodemográficas, con control de posibles factores de confusión. Resultados. Las personas de la zona meridional del país tenían alrededor de tres veces más probabilidades de ser de estatura baja que las personas de la zona septentrional. La diferencia entre los estados mexicanos con la estatura promedio más alta y la estatura promedio más baja fue mayor que la diferencia promedio respecto de la estatura entre México y los Estados Unidos de América. La prevalencia más alta de estatura baja se registró en los adultos con menos de seis años de escolaridad, independientemente del sexo, la zona del país, el lugar de residencia (rural o urbano) y la proporción de hablantes de lenguas indígenas en un estado. Además, la prevalencia más alta de estatura baja se observó en el estrato de población más marginada (porcentaje de habitantes sin escolaridad ni servicios, con ingresos bajos y que vivían una comunidad pequeña). Conclusiones. En México, las condiciones de vida de los adultos de estatura baja son más desfavorables que las de los adultos de estatura media o alta, y esto podría contribuir a aumentar la inequidad en materia de salud.
