RESUMEN

BACKGROUND: The Decade of Healthy Aging (2021-2030) emerges as a 10 years strategy to improve the lives of older adults, their families, and the communities in which they live. One of the actions defined in this framework is related to improving the measurement, monitoring, and understanding of characteristics, factors, and needs related to aging and health. The aim was to analyze and assess the process of construction and development of the Strategic Information System on Health, Funcional Dependence and Aging (SIESDE, for its acronym in Spanish). SIESDE will provide strategic information in Mexico at the municipal, state, and national levels that support the public policies on healthy aging. METHODS: The system processes and analyzes the data sources of the Health Information Systems and the National System of Statistical and Geographical Information. SIESDE comprises three components: (1) Design, construction, and evaluation of the indicators; (2) storage, management, and visualization, and (3) diffusion and translation of information. RESULTS: A total of 135 indicators were built on seven themes: (1) demographic, socioeconomic, and aging conditions, (2) health, (3) functional dependence, (4) healthy aging, (5) health services, (6) social and physical environments, and (7) complex indicators. CONCLUSIONS: SIESDE is an effective system for providing an overall view of health, aging, and functional dependence.

RESUMEN

BACKGROUND: Depression in ageing adults is a public health problem. Worldwide studies have identified social and health risk factors for depressive symptoms. However, little is known about their longitudinal determinants in Mexico. OBJECTIVES AND SETTING: To find the prevalence of depressive symptoms and their longitudinal individual and contextual risk factors in Mexican adults aged 50 and older. DESIGN: Secondary data of 6460 persons aged 50 years and older from the Mexican Health and Aging Study were analysed using a 'between-within' panel data analysis approach. RESULTS: The prevalence of depressive symptoms increased from 35% in 2003 to 38% in 2015. The significantly longitudinal factors associated with these symptoms were getting older (OR 1.02, 95% CI 1.01 to 1.03), being a woman (OR 2.39, 95% CI 2.16 to 2.64), less time spent in formal education (0 years and less than 6 years OR 1.52, 95% CI 1.32 to 1.75 and OR 1.33, 95% CI 1.19 to 1.50, respectively), lower net worth (OR 1.13, 95% CI 1.08 to 1.17), being recently unemployed (OR 1.25, 95% CI 1.10 to 1.25), increased (OR 1.17, 95% CI 1.10 to 1.25) or increasing number (OR 1.23, 95% CI 1.15 to 1.31) of chronic conditions, poor (OR 4.68, 95% CI 4.26 to 5.15) or worsened (OR 1.71, 95% CI 1.61 to 1.81) self-rated health and having impairments on instrumental activities of daily living (IADLs) (OR 2.94 95% CI 2.35 to 3.67) or a new IADL impairment (OR 1.67, 95% CI 1.48 to 1.89), as well as having impairments on ADLs (OR 1.51, 95% CI 1.23 to 1.86) or a new ADL impairment (OR 1.34, 95% CI 1.21 to 1.48). CONCLUSIONS: The prevalence of depressive symptoms in Mexican adults aged 50 and older is high. Our findings show that they are longitudinally associated with the individual's demographic, socioeconomic, health and disability characteristics. Efforts in public policy should focus on preventing chronic conditions and disability, as well as fighting inequalities to reduce the prevalence of depressive symptoms.

RESUMEN

Recent studies have focused on the negative effects of loneliness on health and quality of life in older adults. The De Jong Gierveld Loneliness Scale (DJGLS) has been widely used and has proven to be a valid and reliable instrument for loneliness assessment. However, research on this topic and on the validation of measurement scales among the older population is still incipient. The objective of this study was to examine the psychometric properties of the Spanish version of the 11-item DJGLS in Mexican older adults. Data from a representative sample of cognitively intact older adults aged 60 years and over (mean, standard deviation [SD]) age = 72.0 years (SD 8.1) from two Mexican cities (n = 1913), interviewed face to face at their homes during 2018-2019, were analyzed. The psychometric properties of the DJGLS were examined, including (1) construct validity, examined by Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA), discriminate validity and convergent validity, (2) reliability, calculated using Cronbach's alpha. The overall data quality was high, and the scaling assumptions were generally met with few exceptions. Using EFA and CFA, the findings showed that the DJGLS presents a two-factor structure (Social Loneliness and Emotional Loneliness), with 11 items that explain 67.2% of the total variance. Reliability is adequate at the full-scale level (Cronbach´s α = 0.899), also for the two subscales Social and Emotional Loneliness (Cronbach´s α = 0.892 and 0.776, respectively). These results highlight that most participants with a low score for depressive symptoms and or with a high social support score belonged to the "No loneliness" group. The results showed that the Spanish version of the 11-item DJGLS is adequate for use in Mexican older adults and should be used not only for loneliness screening but also for social and emotional loneliness assessment.

RESUMEN

Background: Research suggests a significant association between increasing age and memory impairments. Nevertheless, for some individuals, memory performance stays within or above the normative values of younger subjects. This is known as successful memory aging and is associated with specific neurophysiological features and psychological and lifestyle-related variables. To date, little is known about the association between successful memory aging and intrinsic capacity (IC) defined as "the composite of all the physical and mental (including psychosocial) capacities that an individual can draw on at any point in time" and resilience. Hence, the aim of this study was to determine if longitudinal associations between IC and successful memory aging and resilience exist and to find differences in cognitive performance between Mexican older adults with successful memory aging, older adults with average memory, and older adults with memory impairment. Methods: Longitudinal data from 590 individuals from the third wave (2012) and the Mex-Cog subsample (2016) of the Mexican Health and Aging Study was analysed. Subjects were classified into 3 groups: (1) older adults with successful memory aging (SUMA), (2) older adults with average memory (AVMA), and (3) older adults with memory impairment (IMA). Cognitive domains of orientation, language, attention, constructional praxis, and executive function were evaluated. IC and resilience were measured using items from the MHAS battery. Analysis of variance and multinomial logistic regressions were used to find differences in IC and resilience across the memory aging groups. Results: ANOVAs showed significant differences across the three cognitive performance groups in all cognitive domains. Multinomial logistic regression analyses revealed that respondents with higher scores in the psychological and cognitive domains of IC at baseline were more likely to have successful memory aging in the subsequent wave of the study. More resilient subjects in 2012 were not more likely to become a SUMA in 2016. However, this could be a result of the way resilience was measured. Conclusion: Our main findings suggest that intrinsic capacity could be used as a predictor of successful memory aging specifically in the psychological and the cognitive domains. More longitudinal studies are needed to further examine these associations.

RESUMEN

The WHO defines a possible case of COVID-19 as a person experiencing fever, cough, shortness of breath, and neurological signs including anosmia, ageusia, or dysgeusia. However, experiences from hospitals all over the world have shown that presentations vary widely. Some atypical presentations include cardiac, gastrointestinal, neurological, and cutaneous and while some are driven by the inflammatory response, others are a consequence of the hypercoagulable state. In our emergency department in a private hospital in Mexico City, we received two patients with very different symptoms on the same shift. Two previously healthy men in their 40s presented to the ER with very atypical manifestations of COVID-19. Neither of them complained of fever, cough, or shortness of breath. The first referred a 3-day history of hiccups that had not resolved with metoclopramide. The second presented with an acute episode of altered mental status. While the first case revealed lung involvement of the disease, the second case had a clean chest CT scan. These cases are relevant as manifestations of COVID-19 vary widely, especially in previously healthy young adults.

RESUMEN

INTRODUCTION: Several studies have argued a causal relationship between diabetes and depression, while others have highlighted that their association is a result of common risk factors. Because Mexico is a country with a high prevalence of diabetes, and diabetes and depression are a frequent comorbidity, we chose this country to investigate the longitudinal relationship of these two conditions, focusing on the influence of demographic, health, and socioeconomic factors which could act as common risk factors for both conditions. RESEARCH DESIGN AND METHODS: Using the harmonized Mexican Health and Aging Study, a nationally representative sample of adults older than 50 with a response rate of 93%, we analyzed the longitudinal relationship of diabetes and depressive symptoms using 'between-within' random-effects models, focusing on the effect of demographic, socioeconomic and health factors. RESULTS: While older adults with diabetes reported a higher prevalence of depressive symptoms in the four waves of the study, there was no causal longitudinal association between them once controlling for demographic, socioeconomic and health factors (between-effect OR=0.88, 95% CI 0.77 to 1.01; within-effect OR=0.87, 95% CI 0.69 to 1.11). CONCLUSIONS: There is no causal longitudinal association between diabetes and depression; the higher prevalence of depression among older adults with diabetes seems a result of socioeconomic and health factors that are not exclusive to respondents with diabetes but are more frequent in this group. Our results highlight the importance of prevention and control of chronic conditions as well as the role of socioeconomic inequalities in mental health.

RESUMEN

Subacute thyroiditis is a self-limiting inflammatory disorder, characterized by neck pain or discomfort, a tender diffuse goiter, and sometimes a transient episode of hyperthyroidism followed by euthyroidism and sometimes hypothyroidism. There is usually a normalization of thyroid function within a few weeks. Subacute thyroiditis has a higher incidence in summer and has been linked to a viral or bacterial upper respiratory postinfection inflammatory response. We hereby describe the case of a previously healthy 37-year-old female presenting with subacute thyroiditis associated with a very mild presentation of COVID-19. As most patients with SARS-Cov-2 are asymptomatic, we suggest to rule out SARS-Cov-2 infection in patients presenting with symptoms suggesting SAT.

RESUMEN

AIMS: To understand the epidemiology, progression, and predictive factors of urinary incontinence (UI) in community-dwelling Mexican adults aged ≥ 50 by sex and UI subtypes (stress, urge, and mixed). METHODS: We analyzed longitudinal UI data in community-dwelling adults aged ≥ 50 (7783 women and 5843 men) for the 2012 to 2015 period of the Mexican Health and Aging Study. We estimated mixed, stress, and urgency incontinence prevalence (2012); 2-year cumulative incidence and remissions (2015); and progression (2012-2015). A multivariate analysis was undertaken to evaluate the predictive factors for UI and its subtypes by sex. RESULTS: The prevalence of UI was higher (27.7%) for women (average age 65.9 ± 9.5) than 12.5% men (average age 67.4 ± 9.3) and increased with age in both sexes (26.7% in women 50 to 59, to 48.5% in ≥ 90; and 6.8% in men 50 to 59, to 26.2% ≥ 90). The most frequent UI subtypes were mixed in women and urge in men. The cumulative incidence of UI was higher in women (22.9%) than men (12.3%) while its remission was higher in men than women. Predictive factors for UI in both sexes were depressive symptoms, a higher number of concomitant diseases and a history of falls; while advanced age was a factor only for men. CONCLUSIONS: UI is a common health problem and its prevalence and severity increase with age. Addressing modifiable risk factors such as depression and falls could decrease the prevalence and incidence of UI and its subtypes. Further studies should also focus on the relationship between mixed UI and male mortality.
