Nutritional status of children under five years of age in Rondônia, Brazil Northern region and in Brazil: 2008 to 2019 / Estado nutricional das crianças menores de cinco anos em Rondônia, região Norte e Brasil: 2008 a 2019

ABSTRACT Objective To describe the nutritional profiles of children under five years of age in the state of Rondônia, comparing them with those from the Northern Region of Brazil and from Brazil. Methods This was a time series ecological study. Data were collected from the Food and Nutrition Surveillance System. The information concerned Body Mass Index by age, gender and place of residence. A time-trend analysis was performed using linear regression applying the Prais-Winsten technique and serial autocorrelation verification using the Durbin and Watson test in Stata®16.0. Results There was an annual increasing trend for the thinness, risk of overweight, overweight and obesity regardless of gender, age and location and for extreme thinness, with the exception of girls and for the age of 2 to 5 years, which revealed a stationary trend. Among boys and children of both genders under two years of age, annual growth trends were higher for non-eutrophic nutritional status when compared to the other groups. The growth rates of nutritional disorders found in the Northern region were higher than in the state of Rondônia and in Brazil. Conclusion It is necessary to review health policies aiming at the promotion and prevention of nutritional problems considering the current situation where extreme conditions such as thinness and obesity coexist, with special attention to male children under 2 years of age.

RESUMO Objetivo Descrever o perfil nutricional de crianças menores de cinco anos no estado de Rondônia comparando com dados da Região Norte e do Brasil. Métodos Estudo ecológico do tipo série temporal. Os dados foram coletados do Sistema de Vigilância Alimentar e Nutricional e utilizou-se o Índice de Massa Corporal por idade, sexo e local de moradia.

Entre os meninos e crianças menores de dois anos, as tendências de crescimento foram mais elevadas para o estado nutricional não eutrófico quando comparado aos outros grupos. As taxas de crescimento de agravos nutricionais encontradas na região Norte foram superiores ao estado de Rondônia e ao Brasil. Conclusão É necessário rever as políticas de saúde visando a promoção e prevenção de agravos nutricionais considerando a atualidade e onde coabitam extremos como a magreza e obesidade, com atenção especial às crianças com menos de dois anos e do sexo masculino.

Neck circumference: cutoff points for Brazilian children / Circunferência do pescoço: proposta de pontos de corte para crianças brasileiras

ABSTRACT Objective The objective of the present study was to propose cutoff points of neck circumference for predicting overweight in Brazilian children. Methods We conducted a cross-sectional study with 875 children from public schools in Brazil. Weight, height, and neck circumference were measured. Nutritional status and the risk of complications were assessed based on the values of body mass index and neck circumference. Receiver operating characteristic curve analysis was used to verify the cutoff points. Results The median age was eight years, and the majority of the children had normal weights by body mass index and had no risk of metabolic complications by neck circumference. There was a correlation between neck circumference and body mass index (k=0.689; p<0.005). The mean values proposed for overweight were 29.2 cm for girls and 29.1 cm for boys. Conclusion Neck circumference had a good correlation with body mass index, and the cutoff points proposed can identify overweight in Brazilian children.

Métodos Estudo transversal realizado com 875 crianças. Foram mensurados peso, estatura e circunferência do pescoço. O diagnóstico do estado nutricional e risco de complicações foi realizado com base nos valores de índice de massa corporal e circunferência de pescoço. Para verificar os pontos de corte foi utilizada a curva Característica de Operação do Receptor. Resultados A mediana de idade foi de oito anos e a maioria das crianças apresentou eutrofia pelo índice de massa corporal e nenhum risco de complicações metabólicas. Observou-se correlação substancial entre a circunferência do pescoço com o índice de massa corporal (k=0,689; p<0,005). Os valores médios de circunferência de pescoço propostos para excesso de peso foi 29,2 cm para meninas e 29,1 cm para meninos. Conclusão A circunferência do pescoço possui boa correlação com o índice de massa corporal e os pontos de corte aqui propostos possuem força para identificar crianças brasileiras com excesso de peso.

Consumption of differently processed food by public school adolescents / Consumo alimentar de adolescentes de escolas públicas segundo grau de processamento industrial dos alimentos

ABSTRACT Objective To characterize food consumption, considering the degree of industrial food processing by public schools' adolescents. Methods Cross-sectional study involving adolescents aged 14 to 19 years, of both genders, attending public schools in Juiz de Fora, MG. Food consumption was assessed using two 24-hour dietary recalls. Foods were classified into three groups according to the degree of industrial processing: (1) unprocessed foods or minimally processed foods, culinary ingredients and preparations based on these foods; (2) processed foods; (3) ultra-processed foods. In addition, weight and height information was collected, with subsequent calculation of body mass index/age to assess the individuals' nutritional status according to the gender. Pearson's chi-square, Mann-Whitney and Kruskal-Wallis tests were performed, adopting a value of p<0.05. Results The sample consisted of 804 adolescents, with a predominance of females (57.5%). In the sample, 29.9% and 26.1%, of girls and boys, respectively, were overweight. There was a difference in the daily consumption of ready-made sweet-tasting foods, being higher in females (26.2%) when compared to males (18.1%), whereas the consumption of soft drinks (one to four times a week) was 47.2% and 55.6% in girls and boys, respectively (p<0.05). Higher consumption of ultra-processed foods was observed in females (p=0.02) and processed foods in males (p=0.008). Conclusion There was a high contribution of ultra-processed foods in the diet of adolescents in public schools; a high prevalence of overweight was observed in both genders.

Métodos Estudo transversal com adolescentes de 14 a 19 anos de ambos os sexos matriculados em escolas públicas de Juiz de Fora, MG. O consumo alimentar foi avaliado através de dois recordatórios de 24h. Os alimentos foram classificados em três grupos de acordo com o grau de processamento industrial: (1) alimentos in natura ou minimamente processados, ingredientes culinários e preparações a base desses alimentos; (2) alimentos processados; (3) alimentos ultraprocessados. Ademais, foram coletadas informações de peso e altura dos estudantes, com posterior cálculo de índice de massa corporal/idade para avaliação do estado nutricional conforme o sexo. Foram realizados os testes Qui-quadrado de Pearson, Mann-Whitney e Kruskal-Wallis, adotando o valor de p<0,05. Resultados A amostra foi composta por 804 adolescentes, com predomínio do sexo feminino (57,5%). Entre os adolescentes, 29,9% das meninas e 26,1% dos meninos apresentaram excesso de peso. Observou-se diferença no consumo diário de alimentos prontos de sabor doce, sendo maior no sexo feminino (26,2%) quando comparado ao masculino (18,1%), ao passo que o consumo de refrigerantes de uma a quatro vezes na semana foi de 47,2% e 55,6% nas meninas e meninos, respectivamente (p<0,05). Maior consumo de alimentos ultraprocessados foi observado no sexo feminino (p=0,02) e de alimentos processados no sexo masculino (p=0,008). Conclusão Verificou-se elevada contribuição proveniente do grupo dos alimentos ultraprocessados na dieta dos adolescentes de escolas públicas, com altas prevalências de excesso de peso em ambos os sexos.

Prevalence and Determinants of the Co-Occurrence of Overweight or Obesity and Micronutrient Deficiencies among Adults in the Philippines: Results from a National Representative Survey.

The double burden of malnutrition (DBM) affects many low- and middle-income countries. However, few studies have examined DBM at the individual level, or undernutrition and overnutrition co-occurring within the same person. This study aims to investigate the prevalence and determinants of DBM among adults in the Philippines. Data from the 2013 National Nutrition Survey were used. The sample size in the analysis was 17,010 adults aged ≥20 years old, after excluding pregnant and lactating women. DBM was defined as the co-occurrence of overweight/obesity and anemia (definition #1), overweight/obesity and anemia or vitamin A deficiency (definition #2), and overweight/obesity and anemia or vitamin A deficiency or iodine insufficiency (definition #3). Anthropometric measurements and biochemical markers were used for DBM assessment. Data were analyzed using descriptive statistics, the chi-square test, and logistic regression by R software. Results showed that definition #3 is the predominant type of DBM (7.0%) in the general population, whereas the prevalence of DBM has increased to 23.7% in overweight/obese persons. Sex, age, educational attainment, marital status, household size, wealth quintile, and smoking status were the determinants of DBM. This study revealed that Filipino adults experience malnutrition critically and must be addressed through food and nutrition interventions.

IL-6 and Soluble Receptors in Overweight and Obese African American Women With and Without Breast Cancer.

Interleukin 6 (IL-6) and its receptors are expressed in approximately half of breast cancer (BC) tissues, and high serum IL-6 levels are associated with poor prognosis. African American (AA) patients with BC have higher serum IL-6 levels compared to Caucasians, suggesting additional risk of disease-related complications in AAs. The purpose of this study was to compare IL-6 complex biomarkers in AA women with and without a history of BC. We conducted a secondary analysis of phenotypic data from two studies of weight loss in AA women with and without a history of BC who had similar age and adiposity. Biomarkers analyzed included tumor necrosis factor alpha (TNF-α), IL-6, IL-6 soluble receptor (IL6sr), and soluble glycoprotein 130 (GP130); IL6sr and GP130 were newly analyzed for this study. TNF-α levels were 1.86 times higher in the BC group (N = 7) compared to those without BC (N = 10; p < 0.001) despite similar age, weight, and body mass index. GP130 levels tended to be higher in women with BC; IL-6 and Il-6 sr were not different between groups. There was a strong correlation between GP130 and TNF-α (r = .638; p = .006) in the group overall. High TNF-α levels in the BC group and a strong correlation between GP130 and TNF-α in the overall group suggest the presence of IL-6 complex initiated TNF-α production. Further study is needed to evaluate IL-6 reduction through a variety of approaches, including weight loss and anti-IL-6 therapies, which may ultimately implicate the reduction of IL-6 complex associated BC-specific recurrence and mortality.

Actual causes of death in Alaska.

We estimated 2011-2015 Alaska mortality from modifiable behavioural risk factors using relative risks, hazard ratios, and population attributable fraction estimates from a comprehensive review of peer-reviewed literature; prevalence estimates from government reports; as well as data from the Alaska Department of Environmental Conservation for 2011-2015. To identify the number of deaths attributable to specified risk factors, we used mortality data from the Alaska Division of Public Health, Health Analytics & Vital Records Section. Data included actual reported deaths of Alaska residents for 2011-2015 that matched relevant underlying International Classification of Diseases and Related Health Problems 10th Revision codes. The actual causes of death in Alaska in 2011-2015 were estimated to be overweight/physical inactivity (20% of all deaths, 26% of Alaska Native deaths), smoking (18%/18%), alcohol consumption (9%/13%), firearms (4%/4%), and drug use (3%/3%). Other actual causes of death included microbial agents (3%/4%), motor vehicles (2%/2%), and environmental pollution (1%/1%). This updated methodology reveals that overweight/physical inactivity was the leading cause of death in Alaska, followed closely by smoking. Just three preventable causes made up almost 60% of all deaths, and almost 70% of deaths among Alaska Native people, both highlighting disparities and underscoring prevention needs.

Vitamin D3 Supplementation Increases Long-Chain Ceramide Levels in Overweight/Obese African Americans: A Post-Hoc Analysis of a Randomized Controlled Trial.

Sphingolipid metabolism plays a critical role in cell growth regulation, lipid regulation, neurodevelopment, type 2 diabetes, and cancer. Animal experiments suggest that vitamin D may be involved in sphingolipid metabolism regulation. In this study, we tested the hypothesis that vitamin D supplementation would alter circulating long-chain ceramides and related metabolites involved in sphingolipid metabolism in humans. We carried out a post-hoc analysis of a previously conducted randomized, placebo-controlled clinical trial in 70 overweight/obese African-Americans, who were randomly assigned into four groups of 600, 2000, 4000 IU/day of vitamin D3 supplements or placebo for 16 weeks. The metabolites were measured in 64 subjects (aged 26.0 ± 9.4 years, 17% male). Serum levels of N-stearoyl-sphingosine (d18:1/18:0) (C18Cer) and stearoyl sphingomyelin (d18:1/18:0) (C18SM) were significantly increased after vitamin D3 supplementation (ps < 0.05) in a dose-response fashion. The effects of 600, 2000, and 4000 IU/day vitamin D3 supplementation on C18Cer were 0.44 (p = 0.049), 0.52 (p = 0.016), and 0.58 (p = 0.008), respectively. The effects of three dosages on C18SM were 0.30 (p = 0.222), 0.61 (p = 0.009), and 0.68 (p = 0.004), respectively. This was accompanied by the significant correlations between serum 25-hydroxyvitamin D3 [25(OH)D] concentration and those two metabolites (ps < 0.05). Vitamin D3 supplementations increase serum levels of C18Cer and C18SM in a dose-response fashion among overweight/obese African Americans.

The prevalence of underweight and overweight/obesity and its correlates among adults in Laos: a cross-sectional national population-based survey, 2013.

PURPOSE: The study aimed to assess the prevalence of underweight and overweight or obesity and their sociodemographic, lifestyle, and health factors in a national adult population in Lao People's Democratic Republic (PDR) (Laos). METHODS: A national cross-sectional study based on a stratified cluster random sampling was conducted in 2013. The total sample included 2531 individuals 18-64 years, (females = 59.3%; mean age 38.7 years, SD = 12.8) from Laos. Questionnaire interview, blood pressure and anthropometric measurements, and biochemistry tests were conducted. Multinomial logistic regression was utilized to determine the association between sociodemographic, lifestyle and health status factors, and underweight and overweight or obesity relative to normal weight. RESULTS: Using Asian criteria for body mass index (BMI) classification, 9.7% of the population was underweight (BMI < 18.5, kg/m2), 47.5% had normal weight (BMI 18.5-22.9 kg/m2), 17.5% overweight (23.0-24.9 kg/m2), 19.6% class I obesity (BMI 25.0-29.9 kg/m2), and 5.6% class II obesity (BMI ≥ 30.0 kg/m2) (or 42.8% overweight, class I or class II obesity). In adjusted multinomial logistic regression, female sex (adjusted relative risk ratio-ARRR 0.67, confidence interval-CI 0.45, 0.99), current tobacco use (ARRR 1.57, CI 1.02, 2.41), and having no hypertension (ARRR 0.50, CI 0.26, 0.97) were associated with underweight, and middle and older age (ARRR 1.79, CI 1.41, 2.25), being Lao-Tai (ARRR 1.37, CI 1.06, 1.76), urban residence (ARRR 1.62, CI 1.20, 2.17), having meals outside home (ARRR 1.36, CI 1.04, 1.77), no current tobacco use (ARRR 0.57, CI 0.34, 0.59), low physical activity (ARRR 1.39, CI 1.01, 1.92), having hypertension (ARRR 2.52, CI 1.94, 3.26), and dyslipidaemia (ARRR 1.56, CI 1.21, 2.00) were associated with overweight or obesity. CONCLUSION: A dual burden of both adult underweight and overweight or obesity was found in Laos. Sociodemographic, lifestyle, and health status risk factors were identified for underweight and overweight or obesity, which can help in guiding public health programmes to address both these conditions. LEVEL OF EVIDENCE: Level V, descriptive cross-sectional survey.

Mortality Paradox of Older Italian-Born Men in Australia: The Concord Health and Ageing in Men Project.

Italian migrants are one of the largest groups of older migrants in Australia. Past research has found lower mortality rates in Italian migrants but it is unclear if this persists into older age. Data came from 334 Italian-born and 849 Australian-born men aged 70 years and over participating in a longitudinal study of men's ageing. Male Italian migrants were more likely to smoke, be overweight, and have lower socio-economic status (SES). They also had higher morbidity from diabetes, chronic pain, dementia and depressive symptoms but lower morbidity from heart disease and cancer. There was no age-adjusted mortality difference. However, adjusting for SES, lifestyle and morbidity differences revealed a 25% lower mortality rate (adjusted HR = 0.75; 95% CI 0.57, 0.98) in Italian-born men. Compared to their Australian-born counterparts, older Italian-born men have a lower mortality than expected considering their lower SES, higher smoking and higher morbidity.

Nutrition Label Use Is Related to Chronic Conditions among Mexicans: Data from the Mexican National Health and Nutrition Survey 2016.

BACKGROUND: Non-communicable diseases, such as obesity, diabetes, and hypertension, can be prevented and treated through a balanced nutrient-rich diet. Nutrition labels have been recognized as crucial to preventing obesity and non-communicable diseases through a healthier diet. OBJECTIVE: Our aim was to examine the association between nutrition label use and chronic conditions (overweight, obesity, previously diagnosed diabetes, and hypertension) among an adult Mexican population. DESIGN: This was a cross-sectional study that used data from the Mexican National Health and Nutrition Survey of 2016 (ENSANUT MC 2016). PARTICIPANTS/SETTING: The participants were 5,013 adults aged 20 to 70 years old. Older adults (>70 years), illiterate participants, pregnant women, and participants with implausible blood pressure data were excluded from the sample. The survey was conducted from May to August 2016 in the participants' households. MAIN OUTCOME MEASURES: We measured chronic conditions (overweight, obesity, previously diagnosed diabetes, and hypertension). STATISTICAL ANALYSES PERFORMED: Pearson χ2 test was used to examine the associations among the use of nutrition labels and sociodemographic characteristics and chronic conditions. Multiple logistic regression was used to determine the association between nutrition label use and chronic conditions adjusting for the effect of confounding variables like sex, age, body mass index, education level, marital status, ethnicity, residence area, region, and socioeconomic status. RESULTS: From the total sample, 40.9% (95% CI 38.4% to 43.8%) reported using nutrition labeling. Respondents with overweight or obesity were less likely to use nutrition labels (odds ratio 0.74; P<0.05). Participants who self-reported diabetes had significantly lower odds of nutrition label use than participants who did not report to have diabetes (odds ratio 0.66; P<0.05). Participants having 3 chronic conditions had lower odds of nutrition label use (odds ratio 0.34; P<0.01) relative to having zero chronic conditions. CONCLUSIONS: This study suggests an association between nutrition label use and chronic conditions (obesity and diabetes). These findings demonstrate that people with obesity, diabetes, and a combination of chronic conditions were less likely to use nutrition labels than people without these conditions.

Noncommunicable Diseases Among Syrian Refugees in Turkey: An Emerging Problem for a Vulnerable Group.

Turkey hosts 3.6 million Syrian refugees, which is the highest number of refugees in a single country worldwide. In this study, we examined the status of noncommunicable diseases and their risk factors among Syrian refugees in Turkey. The data for the study come from the 2016 Health Status Survey of Syrian Refugees in Turkey. We used logistic regression and descriptive statistics to analyze four major noncommunicable diseases and their risk factors to assess the health status of Syrians under temporary protection in Turkey. Combined risk factor analysis showed that, as age increases, the risk of having a noncommunicable disease increases: Syrians in Turkey 60-69 years old have the highest risk of noncommunicable diseases followed by those 45-59 years old. Men have a higher risk of noncommunicable diseases than women. The noncommunicable disease status of Syrians in Turkey should be considered given the high economic burden of treatment and the potential length of stay of Syrians in Turkey.

The Impact of Educational Attainment on Black Women's Obesity Rate in the United States.

Over the last two decades, Black women have been disproportionately impacted by the obesity epidemic in the USA. According to the Centers for Disease Control and Prevention (CDC), 56.6% of Black women are overweight or obese compared with 44.4% Hispanic and 32.8% of white women. Social scientists and public health researchers have argued that increasing educational attainment would lead to overall improvements in health outcomes. Using the National Health and Nutrition Examination Survey (NHANES), a nationally representative cross-sectional survey, Cycles 1999-2010, I examined how educational attainment impacts Black women's rate of obesity and C-reactive protein levels (N = 2685). Multiple linear regression was used to analyze the association between body mass index (BMI) and educational attainment. C-reactive protein, inflammation response, was used to measure the body's reaction to being exposed to stress. The results demonstrated that educational attainment among Black women does not decrease their risk of being obese or levels of C-reactive protein. This article provides evidence to support a need to increase awareness of health disparities that disproportionately impact Black women.

Fitness and Fatness Are Both Associated with Cardiometabolic Risk in Preadolescents.

OBJECTIVE: To determine the associations between cardiorespiratory fitness (CRF) and fatness (overweight-obesity) with cardiometabolic disease risk among preadolescent children. STUDY DESIGN: This cross-sectional study recruited 392 children (50% female, 8-10 years of age). Overweight-obesity was classified according to 2007 World Health Organization criteria for body mass index. High CRF was categorized as a maximum oxygen uptake, determined using a shuttle run test, exceeding 35 mL·kg-1·minute-1 in girls and 42 mL·kg-1·minute-1 in boys. Eleven traditional and novel cardiometabolic risk factors were measured including lipids, glucose, glycated hemoglobin, peripheral and central blood pressure, and arterial wave reflection. Factor analysis identified underlying cardiometabolic disease risk factors and a cardiometabolic disease risk summary score. Two-way analysis of covariance determined the associations between CRF and fatness with cardiometabolic disease risk factors. RESULTS: Factor analysis revealed four underlying factors: blood pressure, cholesterol, vascular health, and carbohydrate-metabolism. Only CRF was significantly (P = .001) associated with the blood pressure factor. Only fatness associated with vascular health (P = .010) and carbohydrate metabolism (P = .005) factors. For the cardiometabolic disease risk summary score, there was an interaction effect. High CRF was associated with decreased cardiometabolic disease risk in overweight-obese but not normal weight children (P = .006). Conversely, high fatness was associated with increased cardiometabolic disease risk in low fit but not high fit children (P < .001). CONCLUSIONS: In preadolescent children, CRF and fatness explain different components of cardiometabolic disease risk. However, high CRF may moderate the relationship between fatness and cardiometabolic disease risk. TRIAL REGISTRATION: ACTRN 12614000433606.

Actualizando los abordajes socioculturales de la obesidad: propuestas a partir de Hacking, Bourdieu y Foucault / Updating the sociocultural approaches to obesity: proposals from Hacking, Bourdieu and Foucault / Atualizando abordagens socioculturais da obesidade: propostas baseadas em Hacking, Bourdieu e Foucault

Resumen El aumento de las tasas de obesidad y sus consecuencias negativas, tanto individuales como colectivas, reclama la necesidad de nuevos enfoques científicos, que permitan un abordaje multidisciplinar que integre los factores biológicos y socioculturales, explorando en profundidad tanto los aspectos objetivos como subjetivos de este problema. En este sentido, en el presente trabajo proponemos un conjunto de reflexiones teóricas, que puedan servir como marco crítico de actualización de las aportaciones de corte sociocultural en los debates científicos sobre la obesidad y el sobrepeso. Para ello, primero revisaremos las principales características de los enfoques biológico y sociocultural sobre el tema. Y después pasaremos a proponer dicho conjunto de reflexiones, realizando un análisis de los conceptos de tres teóricos sociales de corte crítico, vistos como modelos potencialmente fértiles pero poco usados en este tipo de tema por distintos motivos.

Abstract The increase in obesity rates and their negative consequences, both individually and collectively, call for the need for new scientific approaches, which allow for a multidisciplinary approach that integrates the biological and sociocultural, exploring in depth both aspects objectives as subjective of this problem. In this connection, in this work we propose a set of theoretical reflections, which can serve as a critical framework for updating sociocultural contributions to the scientific debates on obesity and overweight. In order to that first we will review the main characteristics of the biological and sociocultural approaches on the subject. And then we will propose this set of reflections, performing an analysis of the concepts of three critical social theorists, seen as potentially fruitful but little used models in this type of subject by different reasons.

Body Image, Physical Activity and Cultural Variables Underlying Race and Ethnicity among Latino Men.

BACKGROUND: Overweight and obesity is a significant public health concern among Latino men. Common correlates of obesity that have been examined in previous studies are diet, physical activity, and body image. OBJECTIVES: The aim of this study was to examine whether or not there are differences in body image, physical activity and cultural variables between Mexican and Puerto Rican men. METHODS: Participants completed a health and culture interview, anthropometric measures, a dietary assessment, and an objective measure of physical activity. The results are from the 203 participants who completed the health and culture interview. RESULTS: Mexicans and Puerto Ricans did not differ in their current and ideal body image, body image discrepancy, body satisfaction or how they described their weight. Puerto Ricans watched a greater number of hours of television per day than Mexicans (p < .01). There were no significant differences in their participation in any regular activity designed to improve or maintain their physical fitness, the number of times or length they engaged in this activity, or in their perceived exertion during this activity. Puerto Ricans reported a higher level of familism (p < .01) and machismo (p < .05) than Mexicans. There were no ethnic differences in folk illness beliefs, fatalism or personalism, acculturation level, acculturative stress, or ethnic identity. CONCLUSIONS: Results are discussed in relation to the development of healthy eating, physical activity and body image interventions for Puerto Rican and Mexican men.

Harambee!: A pilot mixed methods study of integrated residential HIV testing among African-born individuals in the Seattle area.

BACKGROUND: African-born individuals in the U.S. are disproportionately affected by HIV yet have low HIV testing rates. We conducted a mixed methods study to assess the uptake and feasibility of a novel strategy for integrating HIV testing into residential health fairs among African-born individuals in Seattle, WA. METHODS: From April to May 2018, we held six health fairs at three apartment complexes with high numbers of African-born residents. Fairs included free point-of-care screening for glucose, cholesterol, body mass index, blood pressure, and HIV, as well as social services and health education. The health fairs were hosted in apartment complex common areas with HIV testing conducted in private rooms. Health fair participants completed a series of questionnaires to evaluate demographics, access to health services, and HIV testing history. We conducted 18 key informant interviews (KIIs) with health fair participants and community leaders to identify barriers to HIV testing among African-born individuals. RESULTS: Of the 111 adults who accessed at least one service at a health fair, 92 completed questionnaires. Fifty-five (61%) were female, 48 (52%) were born in Africa, and 55 (63%) had health insurance. Half of African-born participants accepted HIV testing; all tested negative. The most common reasons for declining testing were lack of perceived risk for HIV and knowledge of HIV status. We identified a high prevalence of non-communicable diseases (NCDs) among health fair participants; among those tested, 77% (55/71) were overweight/obese, 39% (31/79) had blood pressure > 140/90 mmHg, and 30% (22/73) had total cholesterol > 200 mg/dL. KIIs identified community stigma and misinformation as major barriers to HIV testing among African-born individuals. CONCLUSIONS: Residential health fairs are a feasible method to increase HIV testing among African-born individuals in Seattle. The high prevalence of NCDs highlights the importance of integrating general preventive services within HIV testing programs in this population.

Adherence to American Cancer Society and American Institute of Cancer Research dietary guidelines in overweight African American breast cancer survivors.

PURPOSE: The American Cancer Society (ACS) and the American Institute for Cancer Research (AICR) each created dietary and physical activity guidelines to improve cancer survivorship. Despite African American breast cancer survivors (AABCS) having the lowest survival rates of any racial or ethnic group, limited information exists on their adherence to cancer-specific lifestyle recommendations. The study's purpose was to measure adherence to ACS/AICR dietary recommendations in AABCS. METHODS: Two hundred ten AABCS enrolled in the Moving Forward intervention trial, a randomized, community-based, 6-month weight loss study, were assessed for socio-demographics, dietary intake (via food frequency questionnaire), and related health factors at baseline. We operationalized the dietary recommendations put forth by ACS/AICR and created component and total adherence index scores. Descriptive statistics were used to calculate the proportion of women who met recommendations. Student's t test and χ2 tests were used to compare participant characteristics by median adherence scores. RESULTS: The mean total ACS/AICR score was 12.7 ± 2.5 out of 21 points (median, 13; range, 5 to 21). Over 90% were moderately or completely adherent to limiting alcohol and red & processed meat consumption, but the majority failed to meet the other recommendations to eat whole grains, legumes, fruits, vegetables, and avoid added sugars. Women with total scores below the median were younger, with higher BMI, had fewer years of education, and lower income levels. IMPLICATIONS FOR CANCER SURVIVORS: The present study extends the literature on AABCS adherence to cancer survivor-specific dietary guidelines. Findings will inform future dietary lifestyle interventions in this population.

Associations of Asian Ethnicity and Parental Education with Overweight in Asian American Children and Adolescents: An Analysis of 2011-2016 National Health and Nutrition Examination Surveys.

Objectives Asian Americans are highly diverse in cultural, socioeconomic, and health conditions. We aimed to identify socioeconomic and cultural profiles of subgroups of Asian American children at high risk of obesity or overweight to inform targeted interventions. Methods A sample of 841 Asian American children and adolescents ages 6-19 from the 2011-2016 National Health and Nutrition Examination Survey was used. Multivariable logistic regression modeling was conducted. Analyses were also stratified by age (6-11 vs. 12-19). Key variables of interest were Asian ethnicity (Chinese, Korean/Japanese, Filipino, South Asian, and Southeast Asian) and parental educational level. Models adjusted for age, gender, nativity status, parental nativity status, and health insurance coverage. Results Filipino (AOR 2.79; 95% CI 1.30-6.00), Japanese/Korean (AOR 2.55; 95% CI 1.21-5.38), Southeast Asian (AOR 2.54; 95% CI 1.63-3.94), and South Asian (AOR 2.10; 95% CI 1.01-4.36) children ages 6-19 had higher odds of being obese/overweight than Chinese. Filipino (AOR 3.24; 95% CI 1.11-9.49) and Southeast Asian (AOR 2.47; 95% CI 1.22-5.01) ethnicities were associated with higher risk of obesity/overweight in adolescents ages 12-19. Having a parent with a 4-year college or advanced degree was inversely associated with obesity/overweight in US-born Asian adolescents (AOR 0.34; 95% CI 0.14-0.78). Conclusions for Practice Asian American children and adolescents in some Asian ethnic subgroups may be at higher risk of obesity/overweight than in others. Higher parental education level appears to protect US-born Asian American adolescents from being obese/overweight. Multi-sectoral efforts are needed to better understand and address sociocultural processes that increase childhood obesity/overweight in high-risk Asian subgroups.

Adipocyte ADRB3 Down-Regulated in Chinese Overweight Individuals Adipocyte ADRB3 in Overweight.

OBJECTIVES: Activation of ß3-adrenoceptor (ADRB3) is essential in the process of human adipose tissue browning, but obese subjects suffered from reduced ability of brown adipose tissue activation. The present study aims to detect the adipocyte ADRB3 expression in overweight individuals and the relationship between adipocyte ADRB3 expression and adiposity in adults. METHODS: Visceral adipose tissue samples were obtained from 85 subjects who underwent abdominal surgery. ADRB3 mRNA and protein expression levels in mature adipocytes and adipose tissue stromal vascular cells were examined by quantitative real-time PCR and Western blot assay, respectively. UCP-1mRNA expression levels in mature adipocytes were examined by quantitative real-time PCR. RESULTS: The data revealed that ADRB3 mRNA (p = 0.021) and protein (p = 0.025) expression levels in mature adipocytes were significantly higher in the normal-weight than in the overweight group. Similar results were also found for ADRB3 mRNA (p = 0.041) and protein (p = 0.025) expressions of stromal vascular cells. An inverse correlation was verified between mature adipocyte ADRB3 mRNA expression and BMI (r = -0.362, p = 0.012). UCP-1 mRNA expression levels in mature adipocytes were higher in the normal-weight group compared with the overweight group (p = 0.045). CONCLUSION: Adipocyte ADRB3 expression levels were down-regulated before the onset of obesity, which indicated that the reduction of ADRB3 expression might be the cause of compromised adipose tissue browning and obesity rather than the result. Thus, the interference of the ADRB3 pathway in adipocytes may provide a potential treatment target for obesity.

Height, weight and body mass index of Wichí children from Formosa, Argentina. / Talla, peso e índice de masa corporal en niños y niñas wichí de Formosa, Argentina.

This study provides the descriptive, anthropometric data of 194 children (aged 0-18 years) from a Wichi population located in the province of Formosa, Argentina. The objective of this study was to document growth and nutritional status in this indigenous people. Weight, height, and body mass index data were collected and the corresponding Z-scores were estimated using national and international reference standards. Most analyzed parameters were within the normal range. However, it is concerning that a significant percentage of children are overweight, which may indicate that this population is going through a process of westernization that promotes the consumption of high-calorie, highly-processed foods and a lower level of physical activity.

Este trabajo presenta datos antropométricos descriptivos de 194 niños y niñas (0-18 años) de una población wichí de la provincia de Formosa, Argentina. El objetivo fue documentar el crecimiento y el estado nutricional de este pueblo originario. Se tomaron datos de peso, talla e índice de masa corporal y se calcularon los respectivos puntajes Z utilizando referencias nacionales e internacionales. La mayoría de los parámetros analizados caen dentro de los rangos de la normalidad. Sin embargo, es preocupante la presencia de un porcentaje significativo de niñas y niños con sobrepeso, lo cual indicaría que esta población se encuentra atravesando un proceso de occidentalización que promueve el consumo de alimentos procesados hipercalóricos y una menor actividad física.
