The household economic burden of non-communicable diseases in 18 countries

BACKGROUND: Non-communicable diseases (NCDs) are the leading cause of death globally. In 2014, the United Nations committed to reducing premature mortality from NCDs, including by reducing the burden of healthcare costs. Since 2014, the Prospective Urban and Rural Epidemiology (PURE) Study has been collecting health expenditure data from households with NCDs in 18 countries. METHODS: Using data from the PURE Study, we estimated risk of catastrophic health spending and impoverishment among households with at least one person with NCDs (cardiovascular disease, diabetes, kidney disease, cancer and respiratory diseases; n=17 435), with hypertension only (a leading risk factor for NCDs; n=11 831) or with neither (n=22 654) by country income group: high-income countries (Canada and Sweden), upper middle income countries (UMICs: Brazil, Chile, Malaysia, Poland, South Africa and Turkey), lower middle income countries (LMICs: the Philippines, Colombia, India, Iran and the Occupied Palestinian Territory) and low-income countries (LICs: Bangladesh, Pakistan, Zimbabwe and Tanzania) and China. RESULTS: The prevalence of catastrophic spending and impoverishment is highest among households with NCDs in LMICs and China. After adjusting for covariates that might drive health expenditure, the absolute risk of catastrophic spending is higher in households with NCDs compared with no NCDs in LMICs (risk difference=1.71%; 95% CI 0.75 to 2.67), UMICs (0.82%; 95% CI 0.37 to 1.27) and China (7.52%; 95% CI 5.88 to 9.16). A similar pattern is observed in UMICs and China for impoverishment. A high proportion of those with NCDs in LICs, especially women (38.7% compared with 12.6% in men), reported not taking medication due to costs. CONCLUSIONS: Our findings show that financial protection from healthcare costs for people with NCDs is inadequate, particularly in LMICs and China. While the burden of NCD care may appear greatest in LMICs and China, the burden in LICs may be masked by care foregone due to costs. The high proportion of women reporting foregone care due to cost may in part explain gender inequality in treatment of NCDs. (AU)

Revisión sistemática de la efectividad funcional del vendaje neuromuscular en sujetos con inestabilidad de tobillo / A systematic review of the functional effectiveness of kinesiotaping in individuals with ankle instability

INTRODUCCIÓN La inestabilidad de tobillo presenta mayor frecuencia en personas que han sufrido repetidos esguinces de tobillo. Aunque el Kinesio Tape es una técnica masificada en los últimos años en el tratamiento de esta lesión, se desconoce su efectividad. OBJETIVO Determinar la efectividad funcional del Kinesio Tape en individuos con inestabilidad de tobillo. DISEÑO Revisión sistemática. FUENTES DE DATOS Se realizó una búsqueda sistemática de artículos en donde se aplicó Kinesio Tape en sujetos con inestabilidad de tobillo en las siguientes bases de datos: PubMed Central; PubMed/Medline; Cochrane; Embase; Sciencedirect; Biomed Central; CINAHL; Lippincott Williams &Wilkins; SAGE y Wiley-Blackwell. MÉTODOS DE LA REVISIÓN Se seleccionaron solo estudios experimentales tipo ensayo clínico, en donde se interviniera a pacientes con inestabilidad de tobillo mediante la aplicación de Kinesio Tape y que incluyeran al menos una variable de resultado asociada a la función del tobillo. Se aplicó la escala PEDro a cada artículo para medir su calidad metodológica. RESULTADOS Se obtuvieron 364 artículos. Diez cumplieron los criterios de inclusión; cinco de alta y cinco de moderada calidad metodológica. En la mayoría de los artículos se midió más de una variable. Dos artículos presentaron mejoras en la fuerza muscular; cuatro artículos midieron equilibrio, dos observaron mejoras; un artículo observó mejoras en la propiocepción; dos artículos midieron control postural, sin mejoras significativas y un artículo no observó mejoras significativas en control neuromuscular. Estabilidad articular (un artículo), actividad muscular (un artículo) y funcionalidad (un artículo), no reportaron mejoras significativas con el uso de Kinesio Tape. CONCLUSIÓN El Kinesio Tape es efectivo para obtener mejoras en la fuerza muscular, el equilibrio y la propiocepción en individuos con inestabilidad de tobillo. Sin embargo, el Kinesio tape no reporta mejoras significativas en control postural, control neuromuscular, actividad muscular, estabilidad articular y funcionalidad en sujetos con inestabilidad de tobillo.

INTRODUCTION Ankle instability often seen in people who have suffered repeated ankle sprains. Kinesio Tape is a technique widely applied in recent years, despite not having enough evidence to support its application. OBJECTIVE To determine the functional effectiveness of Kinesio Tape in individuals with ankle instability. DESIGN Systematic review. DATA SOURCES A systematic search of articles was performed where Kinesio Tape was applied in subjects with ankle instability in the following databases: PubMed Central; PubMed/Medline; Cochrane; Embase; Sciencedirect; Biomed Central; CINAHL; Lippincott Williams & Wilkins; SAGE and Wiley-Blackwell. METHODS OF THE REVIEW Only clinical trials were selected, in which patients with ankle instability were intervened by applying Kinesio Tape and which included at least one outcome variable associated with ankle function. RESULTS364 articles were found. Ten met the inclusion criteria; five presented high and five moderate methodological quality. In most cases, one article measured more than one variable. Two articles showed improvements in muscle strength. Of four articles that evaluated balance, two observed improvements; one article observe improvements in proprioception; two articles measured postural control, without significant improvements; one article did not observe significant improvements in neuromuscular control. Stability (one article), muscular activity (one article) and functionality (one article) did not report significant improvements with the use of Kinesio Tape. On the other hand, Kinesio tape does not report significant improvements with respect to postural control, neuromuscular control, muscle activity, joint stability and functionality in subjects suffering from ankle instability. CONCLUSION Kinesio Tape is effective for improvement of muscle strength, balance and proprioception in subjects with ankle instability. However, Kinesio Tape does not report significant improvement of postural control, neuromuscular control, muscle activity, joint stability and functionality in people with ankle instability.

Ideal Cardiovascular Health in the southern cone of Latin America.

OBJECTIVE: The American Heart Association developed the concept of 'Ideal Cardiovascular Health', which is based on the presence of ideal levels across seven health factors. The goal of this study is to assess the prevalence of Ideal Cardiovascular Health in the Southern Cone of Latin America. STUDY DESIGN: We conducted a cross-sectional analysis as part of CESCAS I cohort. METHODS: This report included 5458 participants aged between 35 and 75 years who were selected using stratified multistage probability sampling in Argentina, Chile and Uruguay. Interviews included demographic information, the International Physical Activity Questionnaire, and a food frequency questionnaire on dietary habits. Participants were classified as current, former or non-smokers. Weight, height and blood pressure were measured by trained personnel, and fasting cholesterol and glucose plasma levels were measured. RESULTS: Only 0.1% (95% confidence interval [CI]: 0.0-0.2) met the seven criteria that define the Ideal Cardiovascular Health. The least prevalent healthy behaviour was having a healthy diet: 0.5% (95% CI: 0.3-0.7), while the least prevalent health factor was having blood pressure < 120/80 mmHg: 23.6% (95% CI: 22.1-25.0). CONCLUSIONS: The prevalence of Ideal Cardiovascular Health is very low in a representative sample of population from the Southern Cone of Latin America, and the levels of healthy lifestyle behaviours are even lower than ideal biochemical parameters. These results highlight the challenge of developing strategies to improve the levels of Ideal Cardiovascular Health at primary prevention levels.

Lower tract respiratory infection in children younger than 5 years of age and adverse pregnancy outcomes related to household air pollution in Bariloche (Argentina) and Temuco (Chile).

The main objective of this study was to evaluate the association between household air pollution with lower tract respiratory infection (LRTI) in children younger than 5 years old and adverse pregnancy outcomes. This retrospective cohort study took place in two cities in Patagonia. Using systemic random sampling, we selected households in which at least one child <5 years had lived and/or a child had been born alive or stillborn. Trained interviewers administered the questionnaire. We included 926 households with 695 pregnancies and 1074 children. Household cooking was conducted indoors in ventilated rooms and the use of wood as the principal fuel for cooking was lower in Temuco (13% vs. 17%). In exposed to biomass fuel use, the adjusted OR for LRTI was 1.87 (95% CI 0.98-3.55; P = 0.056) in Temuco and 1.12 (95% CI 0.61-2.05; P = 0.716) in Bariloche. For perinatal morbidity, the OR was 3.11 (95% CI 0.86-11.32; P = 0.084) and 1.41 (95% CI 0.50-3.97; P = 0.518), respectively. However, none of the effects were statistically significant (P > 0.05). The use of biomass fuel to cook in traditional cookstoves in ventilated dwellings may increase the risk of perinatal morbidity and LRTI.

Psychosocial factors and obesity in 17 high-, middle- and low-income countries: the Prospective Urban Rural Epidemiologic study.

BACKGROUND/OBJECTIVES: Psychosocial stress has been proposed to contribute to obesity, particularly abdominal, or central obesity, through chronic activation of the neuroendocrine systems. However, these putative relationships are complex and dependent on country and cultural context. We investigated the association between psychosocial factors and general and abdominal obesity in the Prospective Urban Rural Epidemiologic study. SUBJECTS/METHODS: This observational, cross-sectional study enrolled 151 966 individuals aged 35-70 years from 628 urban and rural communities in 17 high-, middle- and low-income countries. Data were collected for 125 290 individuals regarding education, anthropometrics, hypertension/diabetes, tobacco/alcohol use, diet and psychosocial factors (self-perceived stress and depression). RESULTS: After standardization for age, sex, country income and urban/rural location, the proportion with obesity (body mass index ≥30 kg m(-)(2)) increased from 15.7% in 40 831 individuals with no stress to 20.5% in 7720 individuals with permanent stress, with corresponding proportions for ethnicity- and sex-specific central obesity of 48.6% and 53.5%, respectively (P<0.0001 for both). Associations between stress and hypertension/diabetes tended to be inverse. Estimating the total effect of permanent stress with age, sex, physical activity, education and region as confounders, no relationship between stress and obesity persisted (adjusted prevalence ratio (PR) for obesity 1.04 (95% confidence interval: 0.99-1.10)). There was no relationship between ethnicity- and sex-specific central obesity (adjusted PR 1.00 (0.97-1.02)). Stratification by region yielded inconsistent associations. Depression was weakly but independently linked to obesity (PR 1.08 (1.04-1.12)), and very marginally to abdominal obesity (PR 1.01 (1.00-1.03)). CONCLUSIONS: Although individuals with permanent stress tended to be slightly more obese, there was no overall independent effect and no evidence that abdominal obesity or its consequences (hypertension, diabetes) increased with higher levels of stress or depression. This study does not support a causal link between psychosocial factors and abdominal obesity.

Alcohol consumption and cardiovascular disease, cancer, injury, admission to hospital, and mortality: a prospective cohort study

BACKGROUND:Alcohol consumption is proposed to be the third most important modifiable risk factor for death and disability. However, alcohol consumption has been associated with both benefits and harms, and previous studies were mostly done in high-income countries. We investigated associations between alcohol consumption and outcomes in a prospective cohort of countries at different economic levels in five continents.METHODS:We included information from 12 countries participating in the Prospective Urban Rural Epidemiological (PURE) study, a prospective cohort study of individuals aged 35-70 years. We used Cox proportional hazards regression to study associations with mortality (n=2723), cardiovascular disease (n=2742), myocardial infarction (n=979), stroke (n=817), alcohol-related cancer (n=764), injury (n=824), admission to hospital (n=8786), and for a composite of these outcomes (n=11,963).FINDINGS:We included 114,970 adults, of whom 12,904 (11%) were from high-income countries (HICs), 24,408 (21%) were from upper-middle-income countries (UMICs), 48,845 (43%) were from lower-middle-income countries (LMICs), and 28,813 (25%) were from low-income countries (LICs). Median follow-up was 4.3 years (IQR 3.0-6.0). Current drinking was reported by 36,030 (31%) individuals, and was associated with reduced myocardial infarction (hazard ratio [HR] 0.76 [95% CI 0.63-0.93]), but increased alcohol-related cancers (HR 1.51 [1.22-1.89]) and injury (HR 1.29 [1.04-1.61]). High intake was associated with increased mortality (HR 1.31 [1.04-1.66]). Compared with never drinkers, we identified significantly reduced hazards for the composite outcome for current drinkers in HICs and UMICs (HR 0.84 [0.77-0.92]), but not in LMICs and LICs, for which we identified no reductions in this outcome (HR 1.07 [0.95-1.21]; pinteraction<0.0001)...

Prognostic value of grip strength: findings from the Prospective Urban Rural Epidemiology (PURE) study

BACKGROUND:Reduced muscular strength, as measured by grip strength, has been associated with an increased risk of all-cause and cardiovascular mortality. Grip strength is appealing as a simple, quick, and inexpensive means of stratifying an individual's risk of cardiovascular death. However, the prognostic value of grip strength with respect to the number and range of populations and confounders is unknown. The aim of this study was to assess the independent prognostic importance of grip strength measurement in socioculturally and economically diverse countries.METHODS:The Prospective Urban-Rural Epidemiology (PURE) study is a large, longitudinal population study done in 17 countries of varying incomes and sociocultural settings. We enrolled an unbiased sample of households, which were eligible if at least one household member was aged 35-70 years and if household members intended to stay at that address for another 4 years. Participants were assessed for grip strength, measured using a Jamar dynamometer. During a median follow-up of 4.0 years (IQR 2.9-5.1), we assessed all-cause mortality, cardiovascular mortality, non-cardiovascular mortality, myocardial infarction, stroke, diabetes, cancer, pneumonia, hospital admission for pneumonia or chronic obstructive pulmonary disease (COPD), hospital admission for any respiratory disease (including COPD, asthma, tuberculosis, and pneumonia), injury due to fall, and fracture. Study outcomes were adjudicated using source documents by a local investigator, and a subset were adjudicated centrally.FINDINGS:Between January, 2003, and December, 2009, a total of 142,861 participants were enrolled in the PURE study, of whom 139,691 with known vital status were included in the analysis. During a median follow-up of 4.0 years (IQR 2.9-5.1), 3379 (2%) of 139,691 participants died. After adjustment, the association between grip strength...

The environmental profile of a community's health: a cross-sectional study on tobacco marketing in 16 countries

To examine and compare tobacco marketing in 16 countries while the Framework Convention on Tobacco Control requires parties to implement a comprehensive ban on such marketing.METHODS:Between 2009 and 2012, a kilometre-long walk was completed by trained investigators in 462 communities across 16 countries to collect data on tobacco marketing. We interviewed community members about their exposure to traditional and non-traditional marketing in the previous six months. To examine differences in marketing between urban and rural communities and between high-, middle- and low-income countries, we used multilevel regression models controlling for potential confounders.FINDINGS:Compared with high-income countries, the number of tobacco advertisements observed was 81 times higher in low-income countries (incidence rate ratio, IRR: 80.98; 95% confidence interval, CI: 4.15-1578.42) and the number of tobacco outlets was 2.5 times higher in both low- and lower-middle-income countries (IRR: 2.58; 95% CI: 1.17-5.67 and IRR: 2.52; CI: 1.23-5.17, respectively). Of the 11,842 interviewees, 1184 (10%) reported seeing at least five types of tobacco marketing. Self-reported exposure to at least one type of traditional marketing was 10 times higher in low-income countries than in high-income countries (odds ratio, OR: 9.77; 95% CI: 1.24-76.77). For almost all measures, marketing exposure was significantly lower in the rural communities than in the urban communities.CONCLUSION:Despite global legislation to limit tobacco marketing, it appears ubiquitous. The frequency and type of tobacco marketing varies on the national level by income group and by community type, appearing to be greatest in low-income countries and urban communities.

[Effect of inspiratory muscle training on muscle strength and quality of life in patients with chronic airflow limitation: a randomized controlled trial]. / Efecto del entrenamiento muscular inspiratorio sobre la fuerza muscular y la calidad de vida en pacientes con limitación crónica del flujo aéreo. Ensayo clínico aleatorizado.

OBJECTIVE: Chronic airflow limitation (CAL) is a significant cause of illness and death. Inspiratory muscle training has been described as a technique for managing CAL. The aim of the present study was to evaluate the effectiveness of inspiratory muscle training on improving physiological and functional variables. PATIENTS AND METHODS: Randomized controlled trial in which 35 patients with CAL were assigned to receive either an experimental (n=17) or control (n=18) intervention. The experimental intervention consisted of 2 months of inspiratory muscle training using a device that administered a resistive load of 40% of maximal static inspiratory mouth pressure (PImax). Inspiratory muscle strength, exercise tolerance, respiratory function, and quality of life were assessed. RESULTS: Significant improvement in inspiratory muscle strength was observed in the experimental training group (P=.02). All patients improved over time in both groups (P<.001). PImax increased by 8.9 cm H2O per month of training. Likewise, the health-related quality of life scores improved by 0.56 points. CONCLUSION: Use of a threshold loading device is effective for strengthening inspiratory muscles as measured by PImax after the first month of training in patients with CAL. The long-term effectiveness of such training and its impact on quality of life should be studied in a larger number of patients.

Ensayo clínico aleatorizado / Effect of inspiratory muscle training on muscle strength and quality of life in patients with chronic airflow limitation: a randomized controlled trial

Objetivo: La limitación crónica del flujo aéreo (LCFA) es causa importante de morbimortalidad. Para su manejo se describe la rehabilitación pulmonar, que incluye el entrenamiento muscular inspiratorio. El objetivo del presente estudio fue evaluar la efectividad del entrenamiento muscular inspiratorio par mejorar variables fisiológicas y funcionales. Pacientes y métodos: Ensayo clínico controlado y aleatorizado en 35 pacientes con LCFA, de los que 17 recibieron una intervención experimental y 18 una de control. La intervención experimental consistió en un programa de 2 meses de entrenamiento de músculos inspiratorios usando un dispositivo que administraba una resistencia de un 40% de la presión inspiratoria máxima. Se evaluaron la fuerza muscular inspiratoria, la tolerancia al ejercicio, la función respiratoria y la calidad de vida. Resultados: El tratamiento experimental mostró una mejoría significativa en la fuerza muscular inspiratoria (p = 0,02). Todos los pacientes mejoraron a lo largo del tiempo independientemente del tratamiento experimental (p < 0,001); la presión inspiratoria máxima aumentó en 8,9 cmH2O por mes de entrenamiento; asimismo, hubo un aumento de 0,56 puntos en el cuestionario que evaluó la calidad de vida relacionada con la salud. Conclusión: La utilización específica de un dispositivo de carga umbral es efectiva en el fortalecimiento muscular inspiratorio, medido a través de la presión inspiratoria máxima, al primer mes de entrenamiento en pacientes con LCFA. Es necesario estudiar su efecto a largo plazo y su impacto sobre la calidad de vida en un mayor número de pacientes
