Avaliação da não realização do exame Papanicolaou por meio do Sistema de Vigilância por inquérito telefônico

Objective: To estimate the prevalence of the Pap test and analyze the factors associated with its non-attendance by Brazilian women. Method: Cross-sectional, population-based study in which were used Vigitel (Surveillance System for Protective and Risk Factors for Chronic Diseases by Telephone Survey ) data and were included women in the target age range of the screening. The coverage and prevalence of non-screening were assessed according to sociodemographic, behavioral and health characteristics. Results: Data from 22,580 women were included. About 17.1% of women did not take the Pap test in the three previous years. Women in the age groups of 35-44, 45-54 and 55-64 years showed a higher prevalence of having the test compared to those aged 25-34 years (p<0.05). The following factors were associated with the non-attendance: women with less than 12 years of study (p<0.05), who declared not having a partner (p<0.0001), residents of Northeast, Midwest and North regions (p<0.05), malnourished (p=0.017), who self-assessed their health as negative and presented at least one negative health behavior (p<0.0001). Conclusion: Despite the high coverage of this screening, it remains unsatisfactory in population subgroups, such as women living without a partner, with low educational level, malnourished, who self-assessed their health status as negative, and with at least one negative health behavior

Food environment and fruit and vegetable intake in a urban population: A multilevel analysis

Environmental, social and individual factors influence eating patterns, which in turn affect the risk of many chronic diseases. This study aimed to estimate associations between environmental factors and the consumption of fruit and vegetables among adults in a Brazilian urban context. Data from the surveillance system for risk factors for chronic diseases (VIGITEL) of Brazilian Ministry of Health were used. A cross-sectional telephone survey (VIGITEL – 2008–2010) was carried out with 5826 adults in the urban area of Belo Horizonte. Individual variables were collected. The frequency of fruit and vegetables consumption was assessed from number of servings, weekly frequency and an intake score was calculated. Georeferenced variables were used to characterize the food environment. The density of healthy food outlets (stores specialized in selling fruit and vegetables), unhealthy food outlets (bars, snack bars and food trucks/trailers) and the neighborhood family income were investigated and associated with fruit and vegetables intake score. Weighted multilevel linear regression was used to evaluate the associations between the environment variables and the fruit and vegetables intake score. Higher fruit and vegetables intake scores were observed in neighborhoods with higher density of healthy food outlets and higher income. Lower scores were observed in neighborhood with higher density of unhealthy food outlets. These associations were adjusted by individual variables such as gender, age, physical activity, sugar sweetened beverages consumption, education level and smoking.Higher fruit and vegetables intake scores were observed in neighborhoods with higher density of healthy food outlets and higher income. Lower scores were observed in neighborhood with higher density of unhealthy food outlets. These associations were adjusted by individual variables such as gender, age, physical activity, sugar sweetened beverages consumption, education level and smoking. The food environment might explain some of the socioeconomic disparities with respect to healthy food intake and health outcomes. Healthy food stores are less common in socially disadvantaged neighborhoods, and therefore, healthy foods such as fruits and vegetables are less available or are of a lower quality in lower income areas. Food environment characteristics and neighborhood socioeconomic level had significant associations with fruit and vegetable intake score. These are initial findings that require further investigation within the middle income world populations and the role of the environment with respect to both healthy and unhealthy food acquisition and intake

Fatores associados à incidência de úlcera por pressão durante a internação hospitalar

OBJECTIVE Estimating the incidence rate of pressure ulcers and verifying factors associated with this occurrence in a cohort of hospitalized patients. METHOD This is a cohort study in which the considered outcome was the time until pressure ulcer occurrence. Estimated effect of the variables on the cumulative incidence ratio of the outcome was performed using the Cox proportional hazards model. Variable selection occurred via the Logrank hypothesis test.

Fatores associados ao uso contraindicado de contraceptivos orais no Brasil

OBJETIVO Estimar a prevalência de contraindicação ao uso de anticoncepcionais orais e os fatores associados em mulheres brasileiras. MÉTODOS Participaram 20.454 mulheres que responderam ao inquérito Vigitel em 2008, das quais 3.985 reportaram uso de contraceptivos orais. Definiu-se como uso contraindicado de anticoncepcionais quando presente pelo menos uma condição: hipertensão; doenças cardiovasculares como infarto, derrame/acidente vascular encefálico; diabetes mellitus; ser tabagista e ter idade igual ou maior de 35 anos. Foram estimadas as prevalências e intervalos de 95% de confiança de uso contraindicado em usuárias de anticoncepcionais orais e fatores associados à contraindicação por meio de razões de prevalência e intervalos de 95% de confiança. RESULTADOS Na população total, 21,0% (IC95% 19,7–21,9) das mulheres apresentaram alguma contraindicação ao uso de anticoncepcionais orais, das quais 11,7% (IC95% 10,6–13,7) pertenciam ao grupo de usuárias de anticoncepcionais orais. A contraindicação mais freqüente entre as usuárias de anticoncepcionais orais foi hipertensão (9,1%). A maior proporção de mulheres com pelo menos uma contraindicação tinha entre 45 a 49 anos (45,8%) e escolaridade entre zero e oito (23,8%). A prevalência de contraindicação de anticoncepcionais orais foi maior nas mulheres menos escolarizadas (zero a oito anos de estudos) (RP = 2,46; IC95% 1,57–3,86; p < 0,05) e idade entre 35-44 anos (RP = 4,00; IC95% 2,34–6,83) e 45-49 anos (RP = 5,59; IC95% 2,90–10,75). CONCLUSÕES Idade maior ou igual a 35 e escolaridade baixa foram fatores demográficos e de iniquidade, respectivamente, no uso contraindicado de contraceptivos orais.OBJECTIVE To estimate the prevalence of the contraindicated use of oral contraceptives and the associated factors in Brazilian women. METHODS 20,454 women who answered the VIGITEL survey in 2008 also participated in this study, of which 3,985 reported using oral contraceptives. We defined the following conditions for the contraindicated use of contraceptives: hypertension; cardiovascular diseases such as heart attack, stroke/cerebrovascular accident; diabetes mellitus; being smoker and 35 years old or older. We estimated the prevalence and 95% confidence intervals of contraindicated use in users of oral contraceptives and the factors associated with contraindication by prevalence ratio and 95% confidence intervals. RESULTS In the total population, 21% (95%CI 19.7–21.9) of women showed some contraindication to the use of oral contraceptives, of which 11.7% (95%CI 10.6–13.7) belonged to the group of users of oral contraceptives. The most frequent contraindication in users of oral contraceptives was hypertension (9.1%). The largest proportion of women with at least one contraindication was aged between 45 and 49 years (45.8%) and with education level between zero and eight years (23.8%). The prevalence of contraindication to oral contraceptives was higher in women less educated (zero to eight years of study) (PR = 2.46; 95%CI 1.57–3.86; p < 0.05) and with age between 35-44 years (PR = 4.00; 95%CI 2.34–6.83) and 45-49 years (PR = 5.59; 95%CI 2.90–10.75). CONCLUSIONS Age greater than or equal to 35 and low education level were demographic and iniquity factors, respectively, in the contraindicated use of oral contraceptives

Conhecimento do diagnóstico, tratamento e controle do diabetes mellitus no Brasil

OBJETIVO: Estimar as proporções dos indivíduos que têm conhecimento do diagnóstico, tratamento e controle do diabetes mellitus (DM) na população adulta brasileira. MÉTODO: Este é um estudo transversal, com dados de amostra representativa da população brasileira, provenientes da Pesquisa Nacional de Saúde (PNS 2014/2015). Os desfechos foram definidos com base na medida de hemoglobina glicada (HbA1c), no diagnóstico autorreferido de DM e no uso de hipoglicemiantes ou de insulina. Estimou–se a proporção do conhecimento, tratamento e controle do DM de acordo com as características sociodemográficas, condição de saúde e de acesso aos serviços de saúde, e seus respectivos intervalos de 95% de confiança (IC95%). RESULTADOS: A prevalência de DM na população brasileira foi 8,6% (IC95% 7,8–9,3), 68,2% (IC95% 63,9–72,3) tinham conhecimento do seu diagnóstico, 92,2% (IC95% 88,6–94,7) dos que tinham conhecimento realizam tratamento medicamentoso, e desses, 35,8% (IC95% 30,5–41,6) tinham os níveis de HbA1c controlados. As proporções de conhecimento, controle e tratamento foram menores nos homens, com idade de 18 a 39 anos, indivíduos que possuem baixa escolaridade, sem plano de saúde e beneficiários do Programa Bolsa Família. CONCLUSÃO: Aproximadamente um em cada dez brasileiros apresenta DM. Um pouco mais da metade desta população tem conhecimento do seu diagnóstico, condição aferida por dosagem de HbA1c e diagnóstico clínico. Entre os que sabem, a grande maioria está sob tratamento medicamentoso. Porém, menos da metade destes tem seus níveis de HbA1c controlados. Cenários piores foram encontrados em subgrupos com alta vulnerabilidade social.OBJECTIVE: To estimate the proportions of awareness, treatment, and control of diabetes mellitus (DM) in the Brazilian adult population. METHOD: This is a cross-sectional study, with data from a representative sample of the Brazilian population, taken from the National Health Survey(PNS 2014/2015). Outcomes were defined based on glycated hemoglobin (HbA1c) measurements, self-reported DM diagnosis, and use of hypoglycemic agents or insulin. The proportion of DM awareness, treatment, and control was estimated according to sociodemographic characteristics, health conditions, and access to health services, and their respective 95% confidence intervals. RESULTS: DM prevalence in the Brazilian population was of 8.6% (95%CI: 7.8–9.3): 68.2% (95%CI: 63.9–72.3) were aware of their diagnosis, 92.2% (95%CI: 88.6–94.7) of those who were aware were undergoing drug treatments, and, of these, 35.8% (95%CI: 30.5–41.6) had controlled HbA1c levels. The proportions of DM awareness, control, and treatment were lower in men aged 18 to 39 years, individuals with low education, without health insurance, and beneficiaries of the Bolsa Família program. CONCLUSION: Approximately one in ten Brazilians has DM. A little more than half of this population is aware of their diagnosis, a condition measured by HbA1c dosage and clinical diagnosis. Among those who know, the vast majority are undergoing drug treatments. However, less than half of these have their HbA1c levels controlled. Worse scenarios were found in subgroups with high social vulnerability

Association between the perceived environment and overweight in adults and elderly: a cross-sectional study

Abstract Background Overweight is a global issue of epidemic proportions, and its negative influence on individual health is clear. However, the relation between environment and overweight is not thoroughly clear, especially concerning to the perceived environment and the physical and social aspects. Therefore, this study aimed to analyze potential associations between the perceived environment and overweight in adults and elderly in a medium-sized city. Methods A cross-sectional population-based study was conducted with 808 adult and elderly individuals. Overweight was defined as body mass index ≥25 kg/m2 based on the World Health Organization criteria. The Neighborhood Environment Walkability Scale was used evaluating the perceived environment. Poisson regression was performed evaluating the relationships between the perceived environment and overweight. Results The frequency of overweight was 50.4 %. Adjusted models showed association between overweight and the variable of surrounding neighborhood as follows: “1- to 3-story apartments or condos” (most category; PR = 0.30; CI 0.12–0.76) and “4- to 6-story apartments or condos” (all categories) (PR ranged 0.40 to 0.46; p &lt; 0.05), and also, “land-use mix-diversity” was associated with overweight in this population (PR 0.81; CI 0.66–0.99). Conclusions In addition to individual characteristics, the environmental aspects are relevant to the occurrence of overweight in this population. Population-based studies using primary data on overweight remain scarce in Brazil. Finally, this study contributes to improve the understanding of the complex relationship between perceived environment and overweight, and we believe that our findings provide further justification for the development of future interventions and health promotion strategies. </jats:sec

[Association between exclusive breastfeeding and obesity in children: a cross-sectional study of three Latin American countries].

OBJECTIVE: To determine if breastfeeding for at least the first six months of life is associated with overweight and obesity in children 2 to 5 years old. METHOD: Cross sectional analysis of data from national demographic and health surveys conducted in Bolivia, Colombia and Peru. Overweight and obesity were defined using World Health Organization standard definitions. Odds ratios (OR) were calculated using multinomial logistic regression. RESULTS: The prevalence of obesity in children 2 to 5 years old was 10.4% (95% confidence interval [95%CI]: 8.2-12.6) in Bolivia, 4.9% in Colombia (95%CI: 4.0-5.8), and 6.4% (95%CI: 5.2-8.0) in Peru. Prevalence of exclusive breastfeeding for at least the first 6 months in the study population was 89.9% (95%CI: 87.8-91.9) in Bolivia, 73.9% (95%CI: 72.2-75.6) in Colombia, and 92.8% (95%CI: 91.2-92.4) in Peru. Exclusive breastfeeding was associated with a decreased risk of obesity in children as compared to no breastfeeding or breastfeeding for less than 6 months in Bolivia (OR = .30; 95%CI: .16-.57) and a marginal association in Colombia (OR = .71; 95%CI: .47-1.06) and Peru (OR = .49; 95%CI: 0.23-1.04). No association between breastfeeding and overweight was found. CONCLUSION: Exclusive breastfeeding for at least the first six months of life decreases the risk of obesity in children 2 to 5 years old in Bolivia. A similar but weaker pattern was observed for children in Colombia and Peru

Modelagem de regressão logística multivariada foi utilizada para identificar as variáveis associadas à hipertensão arterial autorreferida com α < 0,05. RESULTADOS A prevalência de hipertensão arterial autorreferida entre os adultos residentes nas capitais brasileiras e Distrito Federal foi de 24,1%. Foram identificadas as seguintes associações com hipertensão arterial autorreferida: faixa etária, tomando 18 a 24 anos como referência, todas as faixas etárias apresentaram maior chance – de 25 a 34 anos (RC = 2,6; IC95% 2,0–3,4) até 65 anos ou mais (RC = 28,1; IC95% 21,7–36,4); baixa escolaridade (9 a 11 anos de estudo – RC = 0,8; IC95% 0,7–0,9; e 12 anos ou mais – RC = 0,6; IC95% 0,6–0,7); raça/cor da pele preta (RC = 1,3; IC95% 1,1–1,5); ser ex-fumante (RC = 1,2; IC95% 1,1–1,3); obesidade (RC = 2,7; IC95% 2,4–3,0); diabetes (RC = 2,9; IC95% 2,5–3,5); e colesterol elevado (RC = 1,9; IC95% 1,8–2,2). CONCLUSÕES Cerca de um quarto da população adulta residente nas capitais brasileiras refere ter hipertensão arterial. As informações do Vigitel são úteis para o monitoramento da hipertensão arterial e identificação de seus fatores associados, subsidiando políticas públicas de promoção, vigilância e atenção à saúde.OBJECTIVE To analyze factors associated with self-reported high blood pressure among adults in Brazilian state capitals. METHODS The study uses data from Sistema de Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (Vigitel – Surveillance System of Risk and Protection Factors of Noncommunicable Diseases by Telephone Survey) collected in 2013. Prevalence rates and their respective 95% confidence intervals by gender were estimated according to sociodemographic variables, lifestyle, reported noncommunicable diseases and self-rated health status. Multivariate logistic regression modeling was used to identify variables associated with self-reported high blood pressure with α < 0.05. RESULTS Prevalence of self-reported high blood pressure among adults living in Brazilian state capitals and the Federal District was 24.1%. The following variables were associated with self-reported high blood pressure: age group, taking 18-24 as reference (all age groups presented increased risk – from 25-34 years [OR = 2.6; 95%CI 2.0–3.4] up to 65 years or more [OR = 28.1; 95%CI 21.7–36.4]); low education level (9 to 11 years of study [OR = 0.8; 95%CI 0.7–0.9] and 12 years or more [OR = 0.6; 95%CI 0.6–0.7]); Black race or skin color (OR = 1.3; 95%CI 1.1–1.5); being a former smoker (OR = 1.2; 95%CI 1.1–1.3); obesity (OR = 2.7; 95%CI 2.4–3.0); diabetes (OR = 2.9; 95%CI 2.5–3.5%), and high cholesterol (OR = 1.9; 95%CI 1.8–2.2). CONCLUSIONS Approximately one quarter of the adult population living in Brazilian state capitals reported having high blood pressure. Information from Vigitel is useful to monitor high blood pressure and identity its associated factors, supporting public policies for health promotion, surveillance and care

The burden of non-communicable diseases attributable to high BMI in Brazil, 1990– 2017 : findings from the Global Burden of Disease Study

Background: The prevalence and burden of disease resulting from obesity have increased worldwide. In Brazil, more than half of the population is now overweight. However, the impact of this growing risk factor on disease burden remains inexact. Using the 2017 Global Burden of Disease (GBD) results, this study sought to estimate mortality and disability-adjusted life years (DALYs) lost to non-communicable diseases caused by high body mass index (BMI) in both sexes and across age categories. This study also aimed to describe the prevalence of overweight and obesity throughout the states of Brazil. Methods: Age-standardized prevalence of overweight and obesity were estimated between 1990 and 2017. A comparative risk assessment was applied to estimate DALYs and deaths for non-communicable diseases and for all causes linked to high BMI. Results: The prevalence of overweight and obesity increased during the period of analysis. Overall, agestandardized prevalence of obesity in Brazil was higher in females (29.8%) than in males (24.6%) in 2017; however, since 1990, males have presented greater rise in obesity (244.1%) than females (165.7%). Increases in prevalence burden were greatest in states from the North and Northeast regions of Brazil. Overall, burden due to high BMI also increased from 1990 to 2017. In 2017, high BMI was responsible for 12.3% (8.8–16.1%) of all deaths and 8.4% (6.3– 10.7%) of total DALYs lost to non-communicable diseases, up from 7.2% (4.1–10.8%), and 4.6% (2.4-6.0%) in 1990, respectively. Change due to risk exposure is the leading contributor to the growth of BMI burden in Brazil. In 2017, high BMI was responsible for 165,954 deaths and 5,095,125 DALYs. Cardiovascular disease and diabetes have proven to be the most prevalent causes of deaths, along with DALYs caused by high BMI, regardless of sex or state. Conclusions: This study demonstrates increasing age-standardized prevalence of obesity in all Brazilian states. High BMI plays an important role in disease burdens in terms of cardiovascular diseases, diabetes, and all causes of mortality. Assessing levels and trends in exposures to high BMI and the resulting disease burden highlights the current priority for primary prevention and public health action initiatives focused on obesity
