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. RESULTS The sample consisted of 442 adults, with 25 incidents of pressure ulcers. Patients with high scores on the Braden scale presented a higher risk of pressure ulcer incidence when compared to those classified into the low score category. CONCLUSION These results reinforce the importance of using the Braden Scale to assist in identifying patients more likely to develop pressure ulcers.OBJETIVO Estimar la tasa de incidencia de úlcera por presión y verificar factores asociados a esa ocurrencia en una cohorte de pacientes hospitalizados.

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

Níveis plasmáticos de vitamina A, carotenóides e proteína ligadora de retinol em crianças com infecções respiratórias agudas e doenças diarréicas
The present study was carried out in order to assess the plasma levels of vitamin A, carotenoids and retinol binding protein (RBP) of three-hundred and eleven children aged from seven months to eleven years, who had a history of upper respiratory infection (URI), pneumonia and diarrhoea. The children were resident in the urban area of the Municipality of S. Paulo, Brazil, and were seen at the pediatric service of the one school-hospital. The data show that plasma vitamin A (µg/dl) and RBP (mg/ dl) levels in the diarrhoea (15.2 µg/dl; 1.7 mg/dl) and pneumonia (15.2 µg/dl; 0.7 mg/dl) groups were lower (pPlanejou-se um estudo com o objetivo de se avaliar os níveis plasmáticos de vitamina A, carotenóides e proteína ligadora de retinol (RBP) em 311 crianças, de 7 meses a onze anos de idade, com história de infecções das vias aéreas superiores (IVAS), pneumonia e diarréia, residentes na área urbana da Cidade de São Paulo, Brasil, e atendidas no serviço de pediatria de um hospital-escola.

Association between parental perceptions of residential neighbourhood environments and childhood obesity in Porto, Portugal
Portugal has one of the highest rates of childhood obesity in Europe. Few studies have explored the relationship between parents’ perceptions of their residential neighbourhood (safety concerns and amenities of the built environment) and their children’s weight status. This study aims to examine the associations between parents’ perceptions of their residential neighbourhood and overweight/obesity among their children. Methods: Anthropometric measures of height and weight were taken for 2690 children in preschools and elementary
schools in Porto. Body mass index (kg/m2 ) was calculated, and the International Obesity Taskforce (IOTF) cut-offs were used. Parents completed the ‘Environmental Module’ standard questionnaire of the International Physical Activity Prevalence Study. Chi-square tests and the logistic regression model adjusted for age, gender, maternal education and school cluster were used to examine the associations between parents’ perceptions of their residential neighbourhood and overweight/obesity among their children. Results: In this sample, 31.8% of the children were overweight (including obese). Significant associations were found between child obesity and the following residential environmental characteristics: the odds of children being obese were lower if their parents believed that it was safe (low/no crime rate) to walk/cycle at night (OR = 0.65, 95% CI = 0.54–0.79) and during the day (OR = 0.70, 95% CI = 0.55–0.86) and that it was easy and pleasant (pedestrian safety) to walk in their neighbourhoods (OR = 0.73, 95% CI = 0.58–0.90) and when local sidewalks were well maintained and unobstructed (OR = 1.18, 95% CI = 1.01–1.40). Conclusion: Parental perceptions of neighbourhood safety and the quality of local sidewalks are significantly associated with obesity values
Recent changes in growth trajectories: a population-based cohort study of over 5 million Brazilian children born between 2001 and 2014
Background: There is limited evidence on recent trends in childhood growth trajectories in Low-/middle-income countries. We investigated how age-trajectories for height and Body Mass Index (BMI) have changed among Brazilian children born in two different time periods after 2000. /
Methods: We used a population-based cohort (part of the “Cohort of 100-Million Brazilians”) created by the linkage of three Brazilian administrative databases: the Cadastro Único of the Federal Government, the National System of Live Births and the National Nutritional and Food Surveillance System. We included longitudinal data on 5,750,214 children who were 3 to <10 years of age and born between 2001 and 2014 (20,209,133 observations). We applied fractional polynomial models with random-effects to estimate mean height and BMI trajectories for children. /
Findings: Compared to children born in 2001–2007, the cohort born in 2008–2014 were on average taller, by a z-score of 0.15 in boys and 0.12 in girls. Their height trajectories shifted upwards, by approximately 1 cm in both sexes. Levels of BMI increased little, by a z-score of 0.06 (boys) and 0.04 (girls). Mean BMI trajectories also changed little. However, the prevalence of overweight/obesity increased between cohorts, e.g., from 26.8% to 30% in boys and 23.9%–26.6% in girls aged between 5 and <10 years. /
Interpretation: An increase of 1 cm in mean height of Brazilian children during a short period indicates the improvement in maternal and child health, especially those from low-income families due to the new health and welfare policies in Brazil. Although mean BMI changed little, the prevalence of child overweight/obesity slightly increased and remained high. /

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 < 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.
