Special Considerations for Healthy Lifestyle Promotion Across the Life Span in Clinical Settings: A Science Advisory From the American Heart Association.

At a population level, engagement in healthy lifestyle behaviors is suboptimal in the United States. Moreover, marked disparities exist in healthy lifestyle behaviors and cardiovascular risk factors as a result of social determinants of health. In addition, there are specific challenges to engaging in healthy lifestyle behaviors related to age, developmental stage, or major life circumstances. Key components of a healthy lifestyle are consuming a healthy dietary pattern, engaging in regular physical activity, avoiding use of tobacco products, habitually attaining adequate sleep, and managing stress. For these health behaviors, there are guidelines and recommendations; however, promotion in clinical settings can be challenging, particularly in certain population groups. These challenges must be overcome to facilitate greater promotion of healthy lifestyle practices in clinical settings. The 5A Model (assess, advise, agree, assist, and arrange) was developed to provide a framework for clinical counseling with consideration for the demands of clinical settings. In this science advisory, we summarize specific considerations for lifestyle-related behavior change counseling using the 5A Model for patients across the life span. In all life stages, social determinants of health and unmet social-related health needs, as well as overweight and obesity, are associated with increased risk of cardiovascular disease, and there is the potential to modify this risk with lifestyle-related behavior changes. In addition, specific considerations for lifestyle-related behavior change counseling in life stages in which lifestyle behaviors significantly affect cardiovascular disease risk are outlined. Greater attention to healthy lifestyle behaviors during every clinician visit will contribute to improved cardiovascular health.

Strategies for Promotion of a Healthy Lifestyle in Clinical Settings: Pillars of Ideal Cardiovascular Health: A Science Advisory From the American Heart Association.

Engagement in healthy lifestyle behaviors is suboptimal. The vast majority of the US population does not meet current recommendations. A healthy lifestyle is defined by consuming a healthy dietary pattern, engaging in regular physical activity, avoiding exposure to tobacco products, habitually attaining adequate amounts of sleep, and managing stress levels. For all these health behaviors there are well-established guidelines; however, promotion in clinical settings can be challenging. It is critical to overcome these challenges because greater promotion of heathy lifestyle practices in clinical settings effectively motivates and initiates patient behavior change. The 5A Model (assess, advise, agree, assist, and arrange) was developed to provide a framework for clinical counseling with requisite attention to the demands of clinical settings. In this science advisory, we present strategies, based on the 5A Model, that clinicians and other health care professionals can use for efficient lifestyle-related behavior change counseling in patients at all levels of cardiovascular disease risk at every visit. In addition, we discuss the underlying role of psychological health and well-being in lifestyle-related behavior change counseling, and how clinicians can leverage health technologies when providing brief patient-centered counseling. Greater attention to healthy lifestyle behaviors during routine clinician visits will contribute to promoting cardiovascular health.

Cardiorespiratory fitness and all-cause mortality in adults diagnosed with cancer systematic review and meta-analysis.

INTRODUCTION: The inverse association between cardiorespiratory fitness and all-cause mortality in apparently healthy populations has been previously reported; however, the existence of this association among adults diagnosed with cancer is unclear. AIM: To determine the association between cardiorespiratory fitness and all-cause mortality in adults diagnosed with cancer. METHODS: Medline, Embase, and SPORTDiscus databases were searched. Eligible prospective cohort studies that examined the association of cardiorespiratory fitness with all-cause mortality in adults diagnosed with cancer were included. Hazard ratios (HRs) with associated 95% confidence intervals (CIs) were extracted from studies for all-cause mortality and pooled HRs were calculated using the random-effects inverse-variance model with the Hartung-Knapp-Sidik-Jonkman adjustment. RESULTS: Data from 13 studies with 6,486 adults were included. Compared with lower levels of cardiorespiratory fitness, high levels were associated with a reduced risk of all-cause mortality among adults diagnosed with any cancer (HR = 0.52; 95% CI, 0.35-0.77), lung cancer (HR = 0.62; 95% CI, 0.46-0.83), and among those with cardiorespiratory fitness measurement via indirect calorimetry (HR = 0.47; 95% CI, 0.27-0.80). Pooled HRs for the reduction in all-cause mortality risk per 1-MET increase were also statistically significant (HR = 0.82; 95% CI, 0.69-0.99). Neither age at baseline nor the length of follow-up had a significant influence on the HR estimates for all-cause mortality risk. CONCLUSION: Cardiorespiratory fitness may confer an independent protective benefit against all-cause mortality in adults diagnosed with cancer. The use of cardiorespiratory fitness as a prognostic parameter might help determine risk for future adverse clinical events and optimize therapeutic management strategies to reduce long-term treatment-related effects in adults diagnosed with cancer.

Association between high blood pressure and fitness and fatness in adolescents / Presión arterial alta asociada con condición física y adiposidad en adolescentes

Abstract Introduction: Excess adiposity is considered the most important risk factor for high blood pressure (HBP) in children and adolescents. Objectives: To explore the association between HBP and overweight (OW) and abdominal obesity (AO), mediated by cardiorespiratory fitness (CRF). To analyze the combined effect of excess adiposity and CRF on HBP among a sample of school-aged children from Montería, Colombia. Materials and methods: Cross-sectional study conducted in a sample of 546 adolescents aged between 11 and 18 years from 14 randomly selected schools in Montería. Blood pressure, anthropometric, and fitness measures were evaluated by trained personnel using standardized protocols and instrumentation. The association of HBP with fitness and fatness was analyzed using logistic regression models. Results: HBP was associated with OW, AO and low CRF. The inclusion of CRF in this model did not attenuate the association between HBP and OW and between HPB and AO. Adolescents with higher adiposity and low CRF were more likely to have HBP compared with those with lower adiposity and high CRF. Moreover, it was found that excess adiposity and low CRF had an additive effect on the risk for HBP among the sample. Conclusion: HBP is a prevalent condition in children and adolescents from Montería, Colombia. HBP is significantly associated with OW, AO, and low CRF; therefore, it is necessary to implement initiatives to promote healthy habits aimed at this population in order to reduce the incidence rate of HBP in Colombian adolescents.

Resumen Introducción. El exceso de adiposidad es considerado como el factor de riesgo más importante para la presión arterial alta (PAA) en niños y adolescentes. Objetivos. Explorar la asociación entre PAA y sobrepeso (SP) y obesidad abdominal (OA), mediada por condición física cardiorrespiratoria (CFC), y analizar el efecto combinado de la adiposidad excesiva y la CFC en la PAA en una muestra de escolares de Montería, Colombia. Materiales y métodos. Estudio transversal realizado en 546 adolescentes con edades entre 11 y 18 años de 14 escuelas seleccionadas aleatoriamente en Montería. Se evaluó la presión arterial, los indicadores antropométricos y la condición física; las mediciones fueron realizadas por personal capacitado mediante el uso de protocolos e instrumentos estandarizados. La asociación de PAA con condición física y adiposidad fue analizada a través de modelos de regresión logística. Resultados. Se encontró una asociación entre PAA y SP, OA y baja CFC. La inclusion de la CFC en el modelo no atenuó la asociación entre PAA y SP y entre PAA y OA. Los adolescentes con mayor adiposidad y baja CFC fueron más propensos a presentar PAA que aquellos con menor adiposidad y alta CFC. Además, se observó que la presencia de adiposidad excesiva y baja CFC aumenta el riesgo de desarrollar PAA. Conclusión. La PAA es una condición prevalente en niños y adolescentes de Montería, además se encontró una asociación estádisticamente significativa entre PAA y SP, OA, y baja CFC, por lo que es necesario que en el país se implementen estrategias que promuevan hábitos saludables en escolares y permitan reducir la tasa de incidencia de PAA en esta población.

Physical activity promotion for patients transitioning to dialysis using the "Exercise is Medicine" framework: a multi-center randomized pragmatic trial (EIM-CKD trial) protocol.

BACKGROUND: Patients on dialysis are physically inactive, with most reporting activity levels below the fifth percentile of healthy age-matched groups. Several small studies have reported efficacy of diverse exercise interventions among persons with CKD and those on dialysis. However, no single intervention has been widely adopted in real-world practice, despite a clear need in this vulnerable population with high rates of mortality, frailty, and skilled nursing hospitalizations. METHODS/DESIGN: We describe a pragmatic clinical trial for an exercise intervention among patients transitioning to dialysis. We will use an existing framework - Exercise is Medicine (EIM) - developed by the American College of Sports Medicine. After undertaking formative qualitative research to tailor the EIM framework to the advanced CKD population (eGFR < 30 ml/min/1.73m2), we will randomize 96 patients from two regions-Atlanta and Bay Area-in two intervention arms with incremental levels of clinical-community integration: physical activity assessment during Nephrology clinical visit, brief counseling at pre-dialysis education, and physical activity wearable (group 1) versus group 1 intervention components plus a referral to a free, EIM practitioner-led group exercise program over 16 weeks (group 2; 8 week core intervention; 8-week follow up). We will assess efficacy by comparing between group differences in minutes/week of objectively measured moderate intensity physical activity. To evaluate implementation, we will use questionnaires for assessing barriers to referral, participation and retention along the path of the intervention. Further we will have a plan for dissemination of the intervention by partnering with relevant stakeholders. DISCUSSION: The overall goal is to inform the development of a practical, cost-conscious intervention "package" that addresses barriers and challenges to physical activity commonly faced by patients with advanced CKD and can be disseminated amongst interested practices. TRIAL REGISTRATION: ClinicalTrials.gov identifier (Dated:10/17/2017): NCT03311763 .

Low Levels of Physical Activity Among Older Persons Living with HIV/AIDS Are Associated with Poor Physical Function.

Antiretroviral therapy (ART) has prolonged lives of persons living with HIV/AIDS (PLWHA), resulting in greater incidence of aging-related diseases and disability. Physical activity (PA) is recommended for healthy aging, but little is known about PA in older PLWHA. The purpose of this study was to objectively assess PA levels in older PLWHA and the associations with physical function. Twenty-one PLWHA, ≥50 years old, on ART with undetectable HIV-1 viral loads, wore an accelerometer to assess PA, including number of steps, activity intensity, and energy expenditure over 7 days. A physical function performance battery assessing aerobic capacity, strength, and gait speed was also completed. Average age was 66, and 67% were male. An average of 3,442 (interquartile range: 4,613) steps were walked daily, with 254.9 kcals expended. Participants spent most waking hours (75%) sedentary, with minimal hours (24%) in light-intensity activity. Only 5 min per day (35 min per week), on average, were spent in moderate-to-vigorous physical activity (MVPA). Maximal gait speed and 6-min walk test significantly correlated (p < .05) with all PA outcomes. Usual gait speed significantly correlated with all PA outcomes, except for daily kcals and light-intensity activity. Greater PA was associated with better physical performance, while high sedentary time was associated with poorer performance. To our knowledge, this is the first study to objectively measure PA in older PLWHA. Our findings indicate that older PLWHA accumulate substantial sedentary time. Most (86%) do not achieve recommended MVPA levels. This activity profile was associated with poor physical function. Providers should promote PA among PLWHA.

Routine Assessment and Promotion of Physical Activity in Healthcare Settings: A Scientific Statement From the American Heart Association.

Physical inactivity is one of the most prevalent major health risk factors, with 8 in 10 US adults not meeting aerobic and muscle-strengthening guidelines, and is associated with a high burden of cardiovascular disease. Improving and maintaining recommended levels of physical activity leads to reductions in metabolic, hemodynamic, functional, body composition, and epigenetic risk factors for noncommunicable chronic diseases. Physical activity also has a significant role, in many cases comparable or superior to drug interventions, in the prevention and management of >40 conditions such as diabetes mellitus, cancer, cardiovascular disease, obesity, depression, Alzheimer disease, and arthritis. Whereas most of the modifiable cardiovascular disease risk factors included in the American Heart Association's My Life Check - Life's Simple 7 are evaluated routinely in clinical practice (glucose and lipid profiles, blood pressure, obesity, and smoking), physical activity is typically not assessed. The purpose of this statement is to provide a comprehensive review of the evidence on the feasibility, validity, and effectiveness of assessing and promoting physical activity in healthcare settings for adult patients. It also adds concrete recommendations for healthcare systems, clinical and community care providers, fitness professionals, the technology industry, and other stakeholders in order to catalyze increased adoption of physical activity assessment and promotion in healthcare settings and to contribute to meeting the American Heart Association's 2020 Impact Goals.

Effect of lifestyle interventions on cardiovascular risk factors among adults without impaired glucose tolerance or diabetes: A systematic review and meta-analysis.

Structured lifestyle interventions can reduce diabetes incidence and cardiovascular disease (CVD) risk among persons with impaired glucose tolerance (IGT), but it is unclear whether they should be implemented among persons without IGT. We conducted a systematic review and meta-analyses to assess the effectiveness of lifestyle interventions on CVD risk among adults without IGT or diabetes. We systematically searched MEDLINE, EMBASE, CINAHL, Web of Science, the Cochrane Library, and PsychInfo databases, from inception to May 4, 2016. We selected randomized controlled trials of lifestyle interventions, involving physical activity (PA), dietary (D), or combined strategies (PA+D) with follow-up duration ≥12 months. We excluded all studies that included individuals with IGT, confirmed by 2-hours oral glucose tolerance test (75g), but included all other studies recruiting populations with different glycemic levels. We stratified studies by baseline glycemic levels: (1) low-range group with mean fasting plasma glucose (FPG) <5.5mmol/L or glycated hemoglobin (A1C) <5.5%, and (2) high-range group with FPG ≥5.5mmol/L or A1C ≥5.5%, and synthesized data using random-effects models. Primary outcomes in this review included systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), and triglycerides (TG). Totally 79 studies met inclusion criteria. Compared to usual care (UC), lifestyle interventions achieved significant improvements in SBP (-2.16mmHg[95%CI, -2.93, -1.39]), DBP (-1.83mmHg[-2.34, -1.31]), TC (-0.10mmol/L[-0.15, -0.05]), LDL-C (-0.09mmol/L[-0.13, -0.04]), HDL-C (0.03mmol/L[0.01, 0.04]), and TG (-0.08mmol/L[-0.14, -0.03]). Similar effects were observed among both low-and high-range study groups except for TC and TG. Similar effects also appeared in SBP and DBP categories regardless of follow-up duration. PA+D interventions had larger improvement effects on CVD risk factors than PA alone interventions. In adults without IGT or diabetes, lifestyle interventions resulted in significant improvements in SBP, DBP, TC, LDL-C, HDL-C, and TG, and might further reduce CVD risk.

Health promoting practices and personal lifestyle behaviors of Brazilian health professionals.

BACKGROUND: This study was conducted to examine the lifestyle behaviors and health promoting practices of physicians, nurses, and community health workers in Brazil. METHODS: A random sample of primary health care units in Brazil was selected, and a pretested questionnaire was administered via phone interviews, in 2011, to 182 physicians, 347 nurses, and 269 community health workers, totaling 798 health professionals. The total initial sample included 1600 eligible health professionals. Variables measured included physical activity, alcohol intake, hours of sleep, diet, and perceived self-efficacy to provide preventive counseling on related lifestyle behaviors. RESULTS: More than 25 % of physicians, nurses, and community health workers reported eating 0-2 portions of fruits and vegetables per day. In terms of cervical and breast cancer, nurses reported to be 'very prepared' to advise patients on these topics more frequently than physicians. The prevalence of smoking ranged from 4.9 % among nurses to 7.4 % among community health workers. The proportion of physical inactivity ranged from 40.3 % among nurses to 52.1 % among community health workers. CONCLUSION: A reasonably high proportion of physicians, nurses, and community health workers report not engaging in healthy lifestyle behaviors that impact chronic diseases, thus, they may be less likely to encourage such behaviors in their patients.

Associations between noncommunicable disease risk factors, race, education, and health insurance status among women of reproductive age in Brazil - 2011.

BACKGROUND: Noncommunicable disease (NCD) risk factors increase the risk of adverse reproductive health outcomes and are becoming increasingly common in Brazil. METHODS: We analyzed VIGITEL 2011 telephone survey data for 13,745 Brazilian women aged 18-44 years in a probabilistic sample from 26 Brazilian state capitals and the Federal District. We examined associations between NCD risk factors (fruit and vegetable intake, leisure time physical activity, alcohol consumption, smoking status, BMI and hypertension status) and race, education, and insurance using chi-square tests and multivariable logistic regression models, estimating the average marginal effects to produce adjusted relative risk ratios (aRRs). Analyses were conducted using SAS 9.3 survey procedures and weighted to reflect population estimates. RESULTS: Women with less than a college education were more likely to report physical inactivity (adjusted relative risk (aRR) and 95% confidence interval = 1.1 (1.1-1.2)), smoking (aRR = 1.7 (1.3-2.2)), and self-reported diagnoses of hypertension (aRR = 2.0 (1.6-2.5)) compared to women with a college education or greater. Similarly, women without health insurance were more likely to report physical inactivity (aRR = 1.1 (1.1-1.2)), smoking (aRR = 1.4 (1.1-1.8)), and self-reported diagnoses of hypertension aRR = 1.4 (1.1-1.7)) compared to women with health insurance. Less variation was found by race and NCD risk factors. CONCLUSION: Targeted public health strategies and policies are needed to increase healthcare access and decrease educational and racial disparities in NCD risk factors among women of reproductive age in Brazil.

The Effect of Exercise Training on Mediators of Inflammation in Breast Cancer Survivors: A Systematic Review with Meta-analysis.

Several sources of evidence indicate that exercise during and after breast cancer could positively modulate the tumor microenvironment. This meta-analysis aimed to determine the effects of exercise training on mediators of inflammation in breast cancer survivors. We searched for randomized controlled trials published from January 1990 to March 2014. An inverse variance method of meta-analysis was performed using a random effects model in the presence of statistical heterogeneity. Eight high-quality trials (n = 478) were included. Exercise improved the serum concentrations of IL6 [weighted mean difference (WMD) = -0.55 pg/mL; 95% confidence interval (CI), -1.02 to -0.09], TNFα (WMD = -0.64 pg/mL; 95% CI, -1.21 to -0.06), IL8 (MD = -0.49 pg/mL; 95% CI, -0.89 to -0.09), and IL2 (WMD = 1.03 pg/mL; 95% CI, 0.40 to 1.67). No significant differences were found in the serum concentrations of C-reactive protein (WMD = -0.15; 95% CI, -0.56 to 0.25) or IL10 (WMD = 0.41; 95% CI, -0.18 to 1.02). Exercise training positively modulates chronic low-grade inflammation in women with breast cancer, which may impact upon carcinogenic mechanisms and the tumor microenvironment. These findings align with the other positive effects of exercise for breast cancer survivors, reinforcing the appropriateness of exercise prescription in this population.

Association of knowledge, preventive counseling and personal health behaviors on physical activity and consumption of fruits or vegetables in community health workers.

BACKGROUND: There is evidence that if a health professional is active and has a healthy diet, he/she is more likely to advise patients about the benefits of physical activity and healthy eating The aims of this study were to: (1) describe the personal physical activity, consumption of fruits and vegetables behaviors and nutritional status of community health workers; (2) evaluate the association between knowledge, delivery of preventive counseling and personal behaviors among community health workers. METHODS: This was a cross-sectional study conducted in a nationally sample of health professionals working in primary health care settings in Brazil in 2011. This survey was part of the second phase of the Guide for Useful Interventions for Activity in Brazil and Latin America project, and data were collected through telephone interviews of 269 community health workers from the Unified Health Care system of Brazil. We applied questionnaires about personal reported behaviors, knowledge and preventive counseling in physical activity and consumption of fruits and vegetables. We calculated the prevalence and associations between the variables with logistic regression. RESULTS: The proportion of community health workers that practiced 150 minutes per week of physical activity in leisure time or transportation was high (64.9%). Half of community health workers were overweight and only 26.2% reported consuming five portions/day of fruits or vegetables. Most community health workers reported counseling about physical activity for more than six months (59.7%), and most were not knowledgeable of the fruits and vegetables and physical activity recommendations. Meeting the fruits and vegetables recommendations was associated with correct knowledge (OR = 4.5; CI95% 1.03;19.7), with reporting 150 minutes or more of physical activity per week (OR = 2.0; CI95% 1.03;3.7) and with reporting physical activity in leisure time (OR = 2.0; CI95% 1.05;3.6). Regular physical activity counseling was associated with reporting 10-149 minutes per week (OR = 3.8; CI95% 1.1;13.3) and with more than 150 minutes of physical activity per week (OR = 4.9; CI95% 1.5;16.5). CONCLUSION: Actions to promote physical activity and healthy eating and to improve knowledge among community health workers within the health care system of Brazil could have a potential positive influence on delivery of preventive counseling to patients on this topic.

Prevalence of health promotion programs in primary health care units in Brazil.

OBJECTIVE: Assessment of prevalence of health promotion programs in primary health care units within Brazil's health system. METHODS: We conducted a cross-sectional descriptive study based on telephone interviews with managers of primary care units. Of a total 42,486 primary health care units listed in the Brazilian Unified Health System directory, 1,600 were randomly selected. Care units from all five Brazilian macroregions were selected proportionally to the number of units in each region. We examined whether any of the following five different types of health promotion programs was available: physical activity; smoking cessation; cessation of alcohol and illicit drug use; healthy eating; and healthy environment. Information was collected on the kinds of activities offered and the status of implementation of the Family Health Strategy at the units. RESULTS: Most units (62.0%) reported having in place three health promotion programs or more and only 3.0% reported having none. Healthy environment (77.0%) and healthy eating (72.0%) programs were the most widely available; smoking and alcohol use cessation were reported in 54.0% and 42.0% of the units. Physical activity programs were offered in less than 40.0% of the units and their availability varied greatly nationwide, from 51.0% in the Southeast to as low as 21.0% in the North. The Family Health Strategy was implemented in most units (61.0%); however, they did not offer more health promotion programs than others did. CONCLUSIONS: Our study showed that most primary care units have in place health promotion programs. Public policies are needed to strengthen primary care services and improve training of health providers to meet the goals of the agenda for health promotion in Brazil.

Characteristics of physical activity programs in the Brazilian primary health care system / Características de programas de atividade física na atenção básica de saúde do Brasil / Características de los programas de actividad física en la atención primaria de salud en Brasil

The aim of this study was to describe the characteristics of programs that promote physical activity in the public primary care system by region of Brazil, subject to the presence or absence of multidisciplinary primary care teams (NASF). We conducted a cross sectional and population-based telephone survey of the health unit coordinators from 1,251 health care units. Coordinators were asked about the presence and characteristics of physical activity programs. Four out of ten health units reported having a physical activity intervention program, the most common involving walking groups. Most of the activities were performed in the morning, once or twice a week, and in sessions of 30 minutes or more. Physical education professionals were primarily responsible for directing the activities. Interventions occurred in the health unit itself or in adjacent community spaces. In general, these characteristics were similar between units with or without NASF, but varied substantially across regions. These findings will guide future physical activity policies and programs within primary care in Brazil.

O objetivo foi descrever as características dos programas de atividade física na atenção básica de saúde de acordo com a presença de Núcleo de Apoio à Saúde da Família (NASF) no município e por regiões do Brasil. Foi realizado um estudo transversal por inquérito telefônico com 1.251 coordenadores de unidades de saúde. Foi aplicado um questionário sobre presença de intervenções com atividade física e suas características de funcionamento. Quatro em cada dez unidades de saúde relataram ter uma intervenção com atividade física, especialmente grupos de caminhada. A maior parte da atividade é realizada na manhã uma vez ou duas vezes por semana, com sessões de 30 minutos ou mais. Profissionais de educação física são os principais responsáveis por supervisionar as atividades. Os programas ocorrem na unidade de saúde ou outros espaços comunitários. Estas características, de modo geral, foram semelhantes entre unidades com ou sem NASF no município e apresentaram variação entre as regiões. Os resultados desse estudo irão permitir melhor direcionamento das próximas ações de promoção de atividade física na atenção básica de saúde.

Se realizó una encuesta transversal telefónica con 1.251 coordinadores de las unidades de salud. Se preguntó a los coordinadores acerca de la presencia y características de intervenciones de actividad física en funcionamiento. Cuatro de cada diez centros de salud reportaron tener una intervención de actividad física, especialmente, grupos de paseo. La mayor parte de las actividades se llevan a cabo por la mañana una vez o dos veces por semana con sesiones de 30 minutos o más. Los profesores de educación física son los principales responsables de la supervisión de las actividades. Los programas se llevan a cabo en la clínica o en otros espacios públicos. Estas características fueron similares en unidades con o sin NASF y mostraron una variación regional en su prevalencia. Estas características permitirán enfocar próximas acciones para promover la actividad física dentro de la atención primaria de salud.

Interventions for the treatment of obesity among children and adolescents in Latin America: a systematic review / Intervenciones para el tratamiento de la obesidad en niños y adolescentes en Latinoamérica: una revisión sistemática

Objective. The objective of this systematic literature review was to identify evidence-based strategies associated with effective healthcare interventions for prevention or treatment of childhood obesity in Latin America. Materials and methods. A systematic review of peer-reviewed, obesity-related interventions implemented in the healthcare setting was conducted. Inclusion criteria included: implementation in Latin America, aimed at overweight or obese children and evaluation of at least one obesity-related outcome (e.g., body mass index (BMI), z-score, weight, and waist circumference, and body fat). Results. Five interventions in the healthcare setting targeting obese children in Latin America were identified. All five studies showed significant changes in BMI, and the majority produced sufficient to large effect sizes through emphasizing physical activity and health eating. Conclusion. Despite the limited number of intervention studies that treat obesity in the healthcare setting, there is evidence that interventions in this setting can be effective in creating positive anthropometric changes in overweight and obese children.

Objetivo. El objetivo de esta revisión sistemática de la literatura fue identificar estrategias basadas en evidencia asociadas con intervenciones en salud efectivas para la prevención y el tratamiento de la obesidad infantil en Latinoamérica. Material y métodos. Se realizó una revisión sistemática por pares de intervenciones relacionadas con la obesidad, que fueron llevadas a cabo en clínicas de atención para la salud. Criterios de inclusión: implementadas en Latinoamérica, dirigidas a niños con obesidad y sobrepeso y evaluación de por lo menos un resultado relacionado con obesidad (ej. índice de masa corporal (IMC), puntaje Z, peso, circunferencia de cintura o grasa corporal). Resultados. Se identificaron cinco intervenciones dirigidas a niños obesos en clínicas de salud en Latinoamérica. Todas las intervenciones mostraron cambios significativos en IMC y la mayoría obtuvo un tamaño del efecto grande a través de la promoción de actividad física y alimentación saludable. Conclusión. A pesar del número limitado de estudios de intervención para tratar la obesidad en clínicas de salud, existe evidencia que las intervenciones en estos lugares pueden ser efectivas en alcanzar cambios antropométricos positivos en los niños con obesidad y sobrepeso.

Should they play outside? Cardiorespiratory fitness and air pollution among schoolchildren in Bogotá / ¿Deberían los niños jugar al aire libre? Acondicionamiento cardiorespiratorio y contaminación del aire en Bogotá

Objective: This study was aimed at comparing cardiorespiratory fitness (CF), measured as VO2 max, amongst school children exposed to varying levels of particulate matter (PM10), and air pollution in Bogotá, Colombia. Methods: This was a cross-sectional study; it involved 1,045 children aged 7-12 attending four public schools served by different public transit routes and systems. Three schools were classified as being highly polluted (HP) and one slightly polluted (SP). The children and their parents were surveyed to collect data regarding their socio-demographic characteristics, physical activity habits and respiratory disease background. Objective measurements of weight and height were used to calculate the body mass index. VO2max was estimated using the 20-meter shuttle-run test, previously validated for Bogotá. Spirometry was performed on 435 children. Results: After adjustment for covariates, no difference was found in VO2max between children attending SP or HP schools (girls SP 45.8 ml/kg/min vs HP 44.6 ml/kg/min, p=0.11; boys SP 47.2 ml/kg/min cf HP 48.2 ml/kg/min, p=0.41). Conclusions: VO2max levels did not differ amongst children attending schools exposed to high compared to low levels of air pollution and PM. A longitudinal study assessing children’s VO2max levels in relation to exposure to highly-polluted areas is warranted.

Objetivo: Comparar el acondicionamiento cardiorespiratorio medido como VO2 máximo en niños escolarizados expuestos a diferentes niveles de PM10 en Bogotá. Métodos: Estudio de corte transversal. Se incluyeron 1045 niños de 7-12 años de 4 colegios públicos con diferentes corredores viales y sistemas de transporte público. Tres colegios tenían alta contaminación (AC) y uno baja contaminación (BC). Se aplicó una encuesta a niños y padres sobre características sociodemográficas, actividad física, antecedentes de enfermedades respiratorias y salud. Se midió objetivamente peso y talla para calcular el índice masa corporal. El VO2 máximo se estimó con la prueba de Leger validada para Bogotá. Se realizaron espirometrias en 435 niños. Resultados: Después de ajustar por covariables, no se encontraron diferencias significativas en el VO2 máximo de los niños en colegios con BC ò AC. (Niñas BC: 45,8ml/kg/min vs. AC: 44,6ml/kg/min; p=0,11, niños BC: 47,2ml/kg/min vs. AC: 48,2ml/kg/min; p=0,41). Conclusión: No se encontraron diferencias en el VO2 máximo de los niños que asistían a los colegios de AC ó BC. Se recomienda un estudio longitudinal que evalúe los niveles de VO2 máximo en los niños expuestos a áreas altamente contaminadas.

Effect of physical inactivity on major non-communicable diseases worldwide: an analysis of burden of disease and life expectancy.

BACKGROUND: Strong evidence shows that physical inactivity increases the risk of many adverse health conditions, including major non-communicable diseases such as coronary heart disease, type 2 diabetes, and breast and colon cancers, and shortens life expectancy. Because much of the world's population is inactive, this link presents a major public health issue. We aimed to quantify the eff ect of physical inactivity on these major non-communicable diseases by estimating how much disease could be averted if inactive people were to become active and to estimate gain in life expectancy at the population level. METHODS: For our analysis of burden of disease, we calculated population attributable fractions (PAFs) associated with physical inactivity using conservative assumptions for each of the major non-communicable diseases, by country, to estimate how much disease could be averted if physical inactivity were eliminated. We used life-table analysis to estimate gains in life expectancy of the population. FINDINGS: Worldwide, we estimate that physical inactivity causes 6% (ranging from 3·2% in southeast Asia to 7·8% in the eastern Mediterranean region) of the burden of disease from coronary heart disease, 7% (3·9-9·6) of type 2 diabetes, 10% (5·6-14·1) of breast cancer, and 10% (5·7-13·8) of colon cancer. Inactivity causes 9% (range 5·1-12·5) of premature mortality, or more than 5·3 million of the 57 million deaths that occurred worldwide in 2008. If inactivity were not eliminated, but decreased instead by 10% or 25%, more than 533 000 and more than 1·3 million deaths, respectively, could be averted every year. We estimated that elimination of physical inactivity would increase the life expectancy of the world's population by 0·68 (range 0·41-0·95) years. INTERPRETATION: Physical inactivity has a major health eff ect worldwide. Decrease in or removal of this unhealthy behaviour could improve health substantially. FUNDING: None.

Time spent traveling in motor vehicles and its association with overweight and abdominal obesity in Colombian adults who do not own a car.

OBJECTIVE: This study examined associations between time spent traveling in motor vehicles per week (TSTMV) and BMI and abdominal obesity (AO) among Colombian adults residing in urban areas who do not own car. METHOD: Secondary data analysis of the 2005 National Nutrition Survey of Colombia was conducted. TSTMV was assessed using the long International Physical Activity Questionnaire. Body composition was measured in 7900 adults. Polytomous and binary logistic regressions were conducted, stratified by gender and adjusted for confounders, including physical activity (PA). RESULTS: Forty-two percent of participants were either overweight or obese according to their BMI, and 22.4% had AO. Males in the middle (10 to 149 min) and highest (>150 min) TSTMV tertiles were more likely to be overweight (POR=1.58, 95% CI=1.13-2.21 and POR=1.55, 95% CI=1.12-2.15 respectively, p-trend=0.012), obese (POR=2.39, 95% CI=1.43-3.99 and POR=1.93, 95% CI=1.22-3.08 respectively, p trend=0.019) and to have AO (POR=1.81, 95% CI=1.18-2.78 and POR=1.73, 95% CI=1.18-2.54 respectively, p-trend=0.009). Associations were not significant in females. CONCLUSIONS: TSTMV was positively associated with overweight and AO in adult Colombian males even after adjusting for PA. These findings highlight the potential deleterious health effects of sedentary behaviors such as prolonged traveling time, independently of having met PA recommendations.

The association between Colombian medical students' healthy personal habits and a positive attitude toward preventive counseling: cross-sectional analyses.

BACKGROUND: Physician-delivered preventive counseling is important for the prevention and management of chronic diseases. Data from the U.S. indicates that medical students with healthy personal habits have a better attitude towards preventive counseling. However, this association and its correlates have not been addressed in rapidly urbanized settings where chronic disease prevention strategies constitute a top public health priority. This study examines the association between personal health practices and attitudes toward preventive counseling among first and fifth-year students from 8 medical schools in Bogotá, Colombia. METHODS: During 2006, a total of 661 first- and fifth-year medical students completed a culturally adapted Spanish version of the "Healthy Doctor = Healthy Patient" survey (response rate = 78%). Logistic regression analyses were used to assess the association between overall personal practices on physical activity, nutrition, weight control, smoking, alcohol use (main exposure variable) and student attitudes toward preventive counseling on these issues (main outcome variable), stratified by year of training and adjusting by gender and medical training-related factors (basic knowledge, perceived adequacy of training and perception of the school's promotion on each healthy habit). RESULTS: The median age and percentage of females for the first- and fifth-year students were 21 years and 59.5% and 25 years and 65%, respectively. After controlling for gender and medical training-related factors, consumption of >or= 5 daily servings of fruits and/or vegetables, not being a smoker or binge drinker were associated with a positive attitude toward counseling on nutrition (OR = 4.71; CI = 1.6-14.1; p = 0.006 smoking (OR = 2.62; CI = 1.1-5.9; p = 0.022), and alcohol consumption (OR = 2.61; CI = 1.3-5.4; p = 0.009), respectively. CONCLUSION: As for U.S. physician and medical students, a positive association was found between the personal health habits of Colombian medical students and their corresponding attitudes toward preventive counseling, independent of gender and medial training-related factors. Our findings, the first relating to this association in medical students in developing regions, also suggest that within the medical school context, interventions focused on promoting healthy student lifestyles can potentially improve future physician's attitudes toward preventive counseling.
