Objective. To estimate the proportion of vaccinated subjects and associated factors in adults and older adults in Mexico. Materials and methods. Analysis of data obtained from the Ensanut Continua 2021-2023 and comparison with the proportion of vaccinated subjects in Ensanut 2012. Results. Given that only 6.8% of adults and older adults in Ensanut Continua 2021-2023 and 17.7% in Ensanut 2012 could accredit their vaccination status, the analysis is based on self-report. When comparing Ensanut Continua 2021-2023 with Ensanut 2012, the proportion of vaccinated subjects according to age group and biologic was as follows: adults aged 20-59 years, tetanus: 66.87 vs. 78.08%; women of childbearing age, tetanus: 71.1 vs. 82.0%; measles/rubella: 36.8 vs. 48.5%; older adults, tetanus: 59.5 vs. 65.86%; influenza: 58.7 vs. 51.9%; pneumococcus: 34.8 vs. 45.9%. Covid-19 vaccine coverage in younger and older adults was 86.6 and 89.2%, respectively. Incomplete schedules were more prevalent in men and in people without health insurance, among adults aged 20 to 59; and in people without health insurance, among adults aged 60 years or older. Discussion. A considerable proportion of adults and older adults are not protected against vaccinepreventable diseases in 2021-2023. [ABSTRACT FROM AUTHOR]

Objective. To estimate the prevalence of metabolic syndrome (MetS) and its association with sociodemographic factors in Mexican older adults (OA). Materials and methods. This study analyzes data from the Mexican National Health and Nutrition Survey 2016. We incorporated data from 804 participants aged 60 years or older. Information on sex, age, body mass index, scholar level, ethnicity, smoking status, geographic region, socioeconomic status, and alcohol consumption was analyzed. For MetS, the International Diabetes Federation harmonized definition was used. Multiple logistic regression models were used to assess the odds ratio (OR) and 95% confidence interval (95%CI) between sociodemographic factors and MetS. Results. The prevalence of MetS was 77.4% (95%CI 72.2,81.9), 71.2% for men, (95%CI 63.2,78.9) and 83.7% for women (95%CI 77.9,88.2). The OA presented higher odds of MetS when they lived with overweight, obesity, and those who had more years of education. Conclusion. The prevalence of MetS among Mexican OA is substantial. Moreover, individuals living with obesity exhibit a heightened odd of experiencing elevated Fasting Plasma Glucose and high blood pressure. This study provides a comprehensive perspective underscoring the imperative for policies aimed at mitigating obesity and addressing other chronic conditions within this population.

Objective. To estimate the prevalence of vaccination history among adults aged 20 to 59 years and 60 years and more by self-report. Materials and methods. Analysis of data obtained from the Encuesta Nacional de Salud y Nutrición 2022 (Ensanut 2022). Results. 27.4% of adults aged 20-39 years reported having received double viral vaccine (measles and rubella [MR]) and 57.3% of adults aged 20-59 years any vaccine containing tetanus toxoid in the last ten years. Among women aged 29-49 years, 18.7% (95%IC: 17.0,20.5) and 58.46% (95%IC: 56.2,60.7) had been vaccinated with MR and Td vaccines, respectively. Among individuals 60 years of age or more, 48.8% (95%IC: 45.9,51.7), 24.4% (95%IC: 22.2,26.8) and 49.1% (95%IC: 46.1,52.2) reported having received Td, pneumococcal vaccine, and seasonal influenza vaccine since September of the year prior to the survey, respectively. Conclusion. The results of this study show that a considerable proportion of adults, women of childbearing age and older adults were not protected against vaccine-preventable diseases in 2022.

Objective. To determine the prevalence and factors related to depressive symptoms in older Mexican adults in urban and rural areas. Materials and methods. Cross-sectional study. We examined older adults from a sample taken from the Mexican Health and Aging Study (MHAS-2018). 14 230 older Mexicans were screened for self-reported depressive symptoms. Results. The prevalence of depressive symptoms was 29.8% (33.4% rural vs. 28.9% urban). In the rural and urban population, the probability of a high prevalence of depressive symptoms was higher in older adults with multimorbidity ≥, severe pain, and fair/poor SRH. Only in the urban population the prevalence of depressive symptoms increased with lower schooling. Conclusion. Identification of the factors related to depressive symptoms may help healthcare professionals provide better treatment for specific groups in the population. [ABSTRACT FROM AUTHOR]

Objetivo. Calcular el costo en que incurre la sociedad por contar con menores de edad que no estudian y que son cuidadores de adultos mayores con dependencia. Material y métodos. Se utilizó el Estudio Nacional de Salud y Envejecimiento en México (Enasem) 2015 para calcular el número de cuidadores menores de edad que no estudian. Se consultó la Encuesta Nacional de Ingresos y Gastos de los Hogares (ENIGH) 2018 para estimar diferencias salariales entre poblaciones con escolaridad de primaria y prepara­toria terminada en edad laboral. Dichas diferencias fueron convertidas a valor presente, agregadas y multiplicadas por el número de cuidadores menores de edad. Resultados. El costo anual total de contar con cuidadores menores de edad que abandonan los estudios asciende a 1 112 179 210 pesos. Conclusiones. El tema de los cuidadores menores de edad no ha recibido la atención requerida de la bibliografía especializada y aún existe una gran brecha de investigación al respecto.

Objective. To calculate the cost assumed by society for having underaged individuals who do not study and provide care to dependent older adults. Materials and methods. The Mexican Health and Ageing Study (MHAS) 2015 was used to calculate the number of underage caregivers who do not attend school. The Household Income and Expenditure Survey (ENIGH) 2018 was used to estimate wage differences between populations at working age with complete elementary and complete high school education. Those differences were then converted to present value, added and multiplied by the number of underage caregivers. Results. The total annual cost of having underage caregivers who drop out of school adds to 1 112 179 210 pesos. Conclusions. The topic concerning underage caregivers has not received enough attention from specialized literature and there is still a large research gap in this area. [ABSTRACT FROM AUTHOR]

Objective. To estimate the out-of-pocket expenses (OOPE) during the last year of life in Mexican older adults (OA). Materials and methods. Estimation of the OOPE corresponding to the last year of life of OA, adjusting by type of management, affiliation and cause of death. Data from the National Health and Aging Study in Mexico (2012) were used. To calculate the total OOPE, the expenses in the last year were used in: medications, medical consultations and hospitalization. The OOPE was adjusted for inflation and is reported in US dollars 2018. Results. The mean OOPE was $6 255.3±18 500. In the ambulatory care group, the OOPE was $4 134.9±13 631.3.The OOPE in hospitalization was $7 050.6±19 971.0. Conclusions. The probability of incurre in OOPE is lower when hospitalization is not required.With hospitalization, affiliation to social security and attending to public hospitals plays a protective role.

Objective. To describe the current status of anemia and iron deficiency (ID), as well as associated sociodemographic characteristics, in older adults (OA). Materials and methods. Serum and capillary blood samples from a sample of OA participants (n=2 902) from the Ensanut 2018-19 were analyzed. ID was defined as s-ferritin<15 μg/L, and anemia was defined according to World Health Organization standards. Logistic regression models were used to associate the characteristics of OA with anemia and ID. Results. Of the OA analyzed, anemia was present in 28.4%, ID in 5% and iron deficiency anemia in 2.07%. Diabetes (OR=2.14), renal insufficiency (OR=10.4), higher age, and urban dwelling (OR=1.35) were conditions associated with higher odds for anemia (p<0.05). Belonging to the 70-79 year age group was the only condition associated with higher odds for ID (OR=1.86, p<0.05). Conclusions. Anemia affects a high proportion of OA, and ID is not the main contributor to anemia. Chronic comorbidities help explain the anemia problem in OA. [ABSTRACT FROM AUTHOR]

Objective. To generate an updated diagnosis of the health conditions, geriatric syndromes, and nutritional status of older Mexican adults. Materials and methods. Descriptive study with a sample of 9 047 older adults aged 60 years and over with national representativeness. We analyzed indicators related to health conditions, geriatric syndromes, and nutritional status, obtaining prevalence as well as tests of differences in proportions and means. Results. Oldest older adults, women, and residents of rural areas showed the highest prevalence of chronic conditions, geriatric syndromes, and poor nutrition. Conclusions. The results of this study offer an updated insight of the health conditions, geriatric syndromes, and nutritional status of older Mexican adults, and show the main health needs that this age group faces, which in turn represent a challenge for the health system in Mexico.

Objective. To determine the association between polypharmacy and multiple health-related outcomes in older adults. Materials and methods. We carried out a cross-sectional analysis with 274 community-dwelling older adults aged ≥60 years in Mexico City. We used the following health-related outcomes: frailty, dementia, functional capacity, falls, disability, and quality of life. The main exposure was polypharmacy (chronic use of six or more drugs). Ordinal logistic regression, binary logistic regression, Poisson regression, and linear regression models were used to estimate the association between polypharmacy and the outcomes analyzed. Results. Polypharmacy was present in 45% of the sample. Polypharmacy was significantly associated with frailty status, and marginally, with dementia. We also observed significant associations for instrumental activities of daily living, falls, disability, and quality of life. Conclusions. Given that polypharmacy has reached levels of a global epidemic, it is necessary to take radical actions to reduce the concomitant problems of the use of multiple drugs. [ABSTRACT FROM AUTHOR]

Objective. To describe energy and nutrient intakes and their adequacies in older Mexican adults participating in the National Health and Nutrition Survey (Ensanut) 2006 and 2012. Materials and methods. Dietary information was obtained through a semiquantitative food frequency questionnaire (SFFQ) from 526 adults 60 y and older participating in Ensanut 2012 and 3 326 in Ensanut 2006 in Mexico. Quantile and logistic regression models were used to obtain medians and marginal effects of each nutrient, adjusting by confounders and survey design. Results. Dietary intake of energy and nutrients was similar in both surveys. Most common micronutrients at risk of dietary deficiency were, for vitamins: A, B-12, C, D and folate, and for minerals: calcium, iron and zinc, in both surveys. Excessive intake of sugar and saturated fat and low fiber intake were common. Conclusions. Diet in older Mexican adults is low in micronutrient essentials, and excessive in fat and sugar. Attention to the diet in this age group through targeted interventions is necessary to promote a healthy diet. [ABSTRACT FROM AUTHOR]

OBJECTIVE: Analyze the impact of a mixed regime of infectious and chronic conditions among older adults in Mexico on their health progression. MATERIALS AND METHODS: A total of 12 207 adults from the Mexican Health and Aging Study were included. Logistic regression analyses were conducted to assess the relationship between self-reported health (SRH) and covariates, including infectious and chronic diseases. Changes in SRH between 2001-2003 were analyzed using multinomial analysis. RESULTS: Older age, low SES, poor SRH and type of disease at baseline increase the odds of poor SRH at follow-up. Odds of poor SRH are highest for persons with both types of diseases (OR 2.63, SE 0.24), followed by only chronic (OR 1.86; SE 0.12) and finally only infectious (OR 1.55; SE 0.25). CONCLUSION: Mexico is experiencing a mixed regime of diseases that affects the health and wellbe-ing of older adults. Despite the rising importance of chronic diseases in countries like Mexico, it is premature to disregard the relevance of infectious diseases for public health.OBJETIVO: Analizar el impacto del régimen epidemiológico mixto presente en México sobre la salud de los adultos mayores. MATERIAL Y MÉTODOS: Participaron adultos mayores de la Encuesta Nacional de Salud y Envejecimiento en México (n=12 207). Se usaron regresiones logísticas para evaluar la relación entre autorreporte de salud (ARS) y variables como enfermedades infecciosas y crónicas. Se analizó el cambio en ARS mediante análisis multinomiales. RESULTADOS: Edad, estatus socioeconómico, pobre ARS y tipo de enfermedad aumentan el riesgo de pobre ARS en el futuro. La razón de probabilidades de pobre ARS fue más alta para individuos con ambos tipos de enfermedad (OR 2.63, SE 0.24), seguida por aquellos con crónicas (OR 1.86; SE 0.12) y aquellos con infecciosas (OR 1.55; SE 0.25). CONCLUSIÓN: El régimen mixto presente en México afecta a los adultos mayores. En países como México, es prematuro dejar de lado el impacto de las enfermedades infecciosas para enfocarse únicamente en prevenir las crónicas.

Objective. To describe de prevalence of iron deficiency (ID) and anemia in a sample of Mexican elderly population from the National Health and Nutrition Survey (Ensanut) 2012. Materials and methods. 1 920 subjects ≥60 years of age were included. Hemoglobin, serum concentrations of ferritin and CRP were measured. The risk for ID and anemia adjusted for potential confounders was assessed in logistic regression models. Results. The overall prevalence of anemia was 13.9%, 15.2% in males and 12.8% females. For ID, overall it was 4.2%, males 4.0% and females 4.3%. The greatest prevalence of ID was found in males and females over 80 years old (6.9 and 7.0%, respectively). ID was present in 1.5 of 10 Mexican elders with anemia. Conclusion. The prevalence of anemia was high in the elderly, however the prevalence of ID was low; there is a need to further investigate the causes of anemia in this age group. [ABSTRACT FROM AUTHOR]
