Prevalence Of Dementia

We read with great interest the review by Nitrini et al. on the prevalence of dementia in Latin America recently published in International Psychogeriatrics (Nitrini et al., 2009). Accurate up-to-date figures are essential for policy-making and planning, therefore the review is very welcome. With unfortunate timing, the 10/66 Dementia Research Group's population-based surveys on the prevalence of dementia were published in the Lancet (Llibre Rodriguez et al., 2008a; 2008b) shortly after this review was submitted to International Psychogeriatrics. The 10/66 surveys included seven sites in five Latin American countries: Peru, Cuba, Dominican Republic, Mexico and Venezuela. The studies were all one-phase catchment area surveys, with samples of 2944 in Cuba and between 1904 and 2011 in other countries, giving a total sample size of 10,794. We present in Table 1 the prevalence of dementia according to our cross-culturally validated 10/66 diagnosis and according to DSM-IV criteria, in each of the Latin American sites, using the same age group stratification as per Nitrini's review. We also present the pooled estimates for each age group. The 10/66 estimates are in general more homogenous than those presented in the review, but similar to the overall pooled estimate. DSM-IV prevalence is lower. We have attributed this discrepancy to an under-reporting of cognitive decline and social/occupational impairment by relatives, particularly in rural and least developed regions (Llibre Rodriguez et al., 2008b). We have shown that, at least for Cuba, the 10/66 Dementia Diagnosis agreed better than the DSM-IV with a clinician gold standard diagnosis, as a high proportion of Clinical Dementia Rating mild and moderate cases were missed by DSM-IV (Prince et al., 2008).

Meta Analyses

Objectives: This study was designed to explore prevalence and correlates of self-reported loneliness and to investigate whether loneliness predicts mortality among older adults (aged 65 or above) in Latin America, China and India.Methods: The study investigated population-based cross-sectional (2003–2007) and longitudinal surveys (follow-up 2007–2010) from the 10/66 Dementia Research Group project. Poisson regression and Cox regression analyses were conducted to analyse correlates of loneliness and its association with mortality.Results: The standardised prevalence of loneliness varied between 25.3 and 32.4% in Latin America and was 18.3% in India. China showed a low prevalence of loneliness (3.8%). In pooled meta-analyses, there was robust evidence to support an association between loneliness and mortality across Latin American countries (HR = 1.13, 95% CI 1.01–1.26, I2 = 10.1%) and China (HR = 1.58, 95% CI 1.03–2.41), but there were no associations in India.Conclusion: Our findings suggest potential cultural variances may exist in the concept of loneliness in older age. The effect of loneliness upon mortality is consistent across different cultural settings excluding India. Loneliness should therefore be considered as a potential dimension of public health among older populations.

Demographic ageing is proceeding especially rapidly in Latin America. Those aged 65 years and over will increase from 33.3 million (6% of the total population) in 2005 to 56.3 million (8.5%) in 2020 and 110.2 million (14.7%) in 2040. A recent review drew attention to the relatively small number of population-based studies of dementia in Latin American countries (Ferri et al, 2005). Estimates based on the literature suggested 1.8 million people with dementia in 2001 increasing to 4.1 million by 2020 and 9.1 million by 2040. The increase, more than a doubling of the number of people with dementia between 2000 and 2020, was the most marked for any world region. Arguably, health and social finance systems are not well placed to meet the needs of the growing numbers of frail and dependent elderly people.

Background: Concern has been raised in India regarding the probable third wave of COVID-19 where children and young age group is thought to get affected the most. There is a lack of serological prevalence data in this age group. We have some interim data from our research for WHO unity protocol, which might help policymakers and the research community to answer such questions based on evidence. Hence, we conducted a study to compare the COVID -19 sero-positivity rate between children and adults Methods/Materials: This is part of an ongoing large multi-centric population-based sero-surveillance study. The study is being conducted in five selected states with a proposed total sample size of 10,000. We have data of 4,500 participants at the time of midterm analysis from four states of India. Total serum antibody against SARS-CoV-2 virus was assessed qualitatively by using a standard ELISA kit. Here we are reporting the interim data of serological prevalence among children aged between 2 to 17 years along with a comparison with ≥18-year old participants. Results: The data collection period was from 15th March 2021 to 10th June 2021. Total available data was of 4,509 participants out of which <18 years were 700 and ≥18 years was 3,809. The site-wise number of available data among the 2-17 year age group were 92, 189, 165, 146 and 108 for the site of Delhi urban resettlement colony, Delhi rural (Villages in Faridabad district under Delhi NCR), Bhubaneswar rural, Gorakhpur rural and Agartala rural area respectively. The seroprevalence was 55.7% in the <18 years age group and 63.5% in the ≥ 18 year age group. There was no statistically significant difference in prevalence between adult and children. Conclusion: SARS-CoV-2 sero-positivity rate among children was high and were comparable to the adult population. Hence, it is unlikely that any future third wave by prevailing COVID-19 variant would disproportionately affect children two years or older.

This study conducted a general and comparative analysis of how university students use mobile digital devices for educational purposes in various places and spaces both inside and outside university facilities in Spain and Latin America. It analyses a total sample of 886 students (442 Spanish and 444 Latin American) corresponding to five Spanish and five Latin American universities. The research methodology was based on factorial analysis and comparison between groups with parametric and nonparametric tests. The results show that educational use of mobile digital devices in the Hispanic world concentrates on the use of smartphones and tablets inside university facilities; primarily in college cafeterias, corridors, classrooms and libraries. Spanish and Latin American students used tablets in and out of University facilities for storing and retrieving information, and smartphones for sharing educational information and content.

Background: The global burden of dementia has increasingly shifted to low- and middle-income regions that lack essential data for monitoring epidemiological progression, and policy and planning support. Drawing upon data that have emerged since the last known estimates published in 2015, this study aims to update dementia estimates in the Latin America and Caribbean (LAC) region for the years 2020, 2030, and 2050 through the application of a recently validated Bayesian approach for disease estimates useful when data sources are scarce.Methods: A comprehensive parallel systematic review of PubMed, EMBASE, PsycINFO, Global Health, and LILACS was conducted to identify prospective population-based epidemiological studies on dementia published in English from 2013 to 2018 in LAC. English and non-English data cited by a recent review on dementia estimates in LAC were also examined for additional data. A Bayesian normal-normal hierarchical model (NNHM) was developed to estimate age-specific and age-adjusted dementia prevalence in people aged 60+. Using age-specific population projections from the UN, the total number of people affected by dementia for the years 2020, 2030, and 2050 were estimated.Results: 1,414 studies were identified, of which only 7 met the inclusion criteria. The studies had 7,684 participants and 1,191 dementia cases. The age-standardized prevalence of all forms of dementia in LAC was 8% (95% CI: 5–11.5%) in people aged 60+. The estimated prevalence varied with age, increasing from 2.5% (95% CI: 0.08–4.0%) in the 60-69 age group, to 9.4% (95% CI: 5.4–13.2%) in the 70–79 age group and 28.9% (95% CI: 20.3–37.2%) in the ≥80 age group. The number of people age 60 and older living with dementia in LAC in 2020 was estimated at 6.86 (95% CI: 4.3–9.8) million, 9.94 (95% CI: 6.16–14.15) million in 2030, and 19.33 (95% CI: 12.3–13.6) million in 2050.Conclusion: We project an upward disease trajectory for dementia in LAC countries. The projection is likely an underestimation of the true dementia burden given the underrepresentation of rural and socio-economically deprived populations. More research is urgently needed to improve the accuracy of disease estimates, guide clinicians to improve evaluations for earlier recognition of dementia, and support the development of effective policies for improving dementia prevention, diagnosis and clinical management in LAC's diverse and aging communities.

BackgroundThe proportion of the global population aged 60 and over is increasing, more so in Latin America than any other region. Depression is common among elderly people and an important cause of disability worldwide.AimsTo estimate the prevalence and correlates of late-life depression, associated disability and access to treatment in five locations in Latin America.MethodA one-phase cross-sectional survey of 5886 people aged 65 and over from urban and rural locations in Peru and Mexico and an urban site in Venezuela. Depression was identified according to DSM–IV and ICD–10 criteria, Geriatric Mental State–Automated Geriatric Examination for Computer Assisted Taxonomy (GMS–AGECAT) algorithm and EURO–D cut-off point. Poisson regression was used to estimate the independent associations of sociodemographic characteristics, economic circumstances and health status with ICD–10 depression.ResultsFor DSM–IV major depression overall prevalence varied between 1.3% and 2.8% by site, for ICD–10 depressive episode between 4.5% and 5.1%, for GMS–AGECAT depression between 30.0% and 35.9% and for EURO–D depression between 26.1% and 31.2%; therefore, there was a considerable prevalence of clinically significant depression beyond that identified by ICD–10 and DSM–IV diagnostic criteria. Most older people with depression had never received treatment. Limiting physical impairments and a past history of depression were the two most consistent correlates of the ICD–10 depressive episode.ConclusionsThe treatment gap poses a significant challenge for Latin American health systems, with their relatively weak primary care services and reliance on private specialists; local treatment trials could establish the cost-effectiveness of mental health investment in the government sector.
