Association between contextual factors and coverage of the Acwy meningococcal vaccine, after three years of its overdue, in the vaccination calendar of adolescents in the state of Minas Gerais, Brazil: global space regressions.

The objective of the study was to analyze the spatial distribution of vaccination coverage of bacterial meningitis vaccine: A, C, W and Y (menacwy) and identify the association between socioeconomic and social environment factors with menacwy vaccine coverage among adolescents in the state of Minas Gerais (MG), Brazil. This is an ecological, mixed study, conducted with secondary data from the 853 municipalities of the State of MG, Brazil, from 2020 to 2022, provided by the information system of the National Immunization Program. For spatial statistical analysis, spatial dependence and the presence of spatial clusters formed by municipalities with high and low vaccination coverage of Menacwy were evaluated. In the year 2021, MG presented the largest vaccination coverage (60.58%) since the introduction of the Menacwy vaccine by the PNI. Regarding the analysis of global regressions, it is observed that for the year 2020, as the MG Index of Social Responsibility-Health increased and MG Index of Social Responsibility-Public Security increased, increased the vaccination coverage of the municipalities of the Menacwy vaccine. Finally, compared to 2021, similar association was observed in relation to the proportion of the population served by the Family Health Strategy of the municipalities of the state of MG and per capita spending on education activities: as this indicator increased, with increased coverage of the Vaccine of the Menacwy vaccine of the state municipalities. They reinforce the importance of assessing the quality-of-care management and health surveillance system, professional training, and damage reduction to populations, especially adolescents.

Environmental and individual factors associated with gestational weight gain.

BACKGROUND: Environmental factors have an impact on inappropriate food choices and sedentary lifestyle, and both individually and in combination these factors favour improper gestational weight gain (GWG) and consequent maternal and neonatal health problems. The objective of this study was to analyze the environmental and individual factors associated with GWG. METHODS: Data were from "Born in Belo Horizonte: Survey on childbirth and birth", a hospital-based retrospective cohort of 506 pregnant women with deliveries in public and private maternity hospitals in Belo Horizonte, Minas Gerais. Data were collected via face-to-face interviews from November 2011 to March 2013. The outcome variable of this study was the GWG categorized based on the Institute of Medicine Guidelines. Explanatory environmental variables included the availability and access to food environment and places available for physical activity in the neighborhood. Explanatory individual variables included socioeconomic and demographic, obstetric and childbirth variables. Generalized estimating equations examined the association of environmental and individual factors with insufficient or excessive GWG. RESULTS: The final sample consisted of 506 mothers. There was 36.4% pregnant women showing excessive GWG and 22.7% showing GWG below the recommended interval. Regarding excessive GWG, there was a positive association with the number of mixed food purchasing establishments close to the place of residence, pre-pregnancy body mass index in the categories of overweight and obesity, arterial hypertension and the private sector as the predominant place for prenatal consultations. CONCLUSION: GWG outside of the recommended interval was associated with individual and environmental factors, and most pregnant women had insufficient or excessive gestational weight gain. Such results can complement previously published evidence, important for creating more effective strategies for the prevention of excessive and inadequate GWG and the consequent problems related to it during pregnancy.

Neighborhood environment is associated with unhealthy food intake in a Brazilian urban area.

Unhealthy food intake is one of the main risk factors for morbidity and mortality for non-communicable diseases (NCDs), and is associated with multiple factors, including the neighborhood environment. The present study aimed to examine the association between the neighborhood context and unhealthy food intake in adults. This is a cross-sectional study, carried out in Belo Horizonte, Brazil. This study used the database of Surveillance System for Risk and Protective Factors for Chronic Diseases by Telephone Survey (Vigitel), which was georeferenced and linked to a database with information on the physical and social realities of a neighborhood context. The administrative boundary of the basic health units (ABBHU) was used as a neighborhood unit. Unhealthy food intake was assessed by the regular consumption of meat with excess fat, soft drinks, and red meat, as well as the irregular consumption of fruits and vegetables. To characterize the physical and social realities of a neighborhood, this study used georeferenced data of establishments selling foods, population density, homicide rates, health vulnerability Index, and total income. For data analysis, multilevel logistic regression was used. The sample consisted of 5783 adults. It was observed that younger, males, people with a lower-level education, who were inactive during leisure time, who had abusive alcohol consumption, and who were current smokers, were associated with a greater chance of having an unhealthy food intake. After adjusting for individual characteristics, it was observed that living in ABBHU, with a low mean income and an extremely high vulnerability, increases the individual's chances of having an unhealthy food intake. An unhealthy food intake is partially explained by demographic characteristics and socioeconomic conditions in the neighborhood. The present study can contribute to improving the understanding of the importance of the urban environment in food choices.

Sugar-sweetened soft drinks consumption and risk of hyperuricemia: Results of the ELSA-Brasil study.

BACKGROUND AND AIMS: The prospective association between sugar-sweetened beverages consumption and hyperuricemia is controversial. The aim was to investigate the association of the consumption of sugar-sweetened soft drinks and unsweetened fruit juices with the incidence of hyperuricemia and the levels of serum uric acid in the participants of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). METHODS AND RESULTS: Longitudinal analysis in ELSA-Brasil participants (baseline 2008-2010 and follow-up 2012-2014). The sample consisted of 10,072 civil servants (35-74 years, both sexes). The consumption of beverages estimated by a food frequency questionnaire (baseline) was divided into five categories: nonconsumption and quartiles (≥0.1 mL/day). Hyperuricemia was defined as uric acid ≥7.0 mg/dL (men) and ≥5.7 mg/dL (women). Poisson regression with robust variance and multiple linear regression were tested. The average consumption of soft drinks was 84 ± 191 mL/day in men and 42 ± 128 mL/day in women. After 4 years of follow-up, the higher consumption of soft drinks (men: 401 ± 303 mL/day; women: 390 ± 290 mL/day) increased the relative risk of hyperuricemia by 30% (men) and 40% (women), and was associated with increased mean uric acid (men: ß = 0.14 mg/dL; 95% CI 0.41-0.24; women: ß = 0.11 mg/dL; 95% CI 0.00-0.21). The consumption of unsweetened juice was not associated with hyperuricemia. CONCLUSION: High consumption of sugar-sweetened soft drinks is associated with an increased relative risk of hyperuricemia and elevated serum uric acid levels in Brazilian adults.

Socioeconomic inequalities in children's health-related quality of life according to weight status.

OBJECTIVES: This study explores the association between socioeconomic position (SEP) and health-related quality of life (HRQoL) among Portuguese children according to their weight status. METHODS: A total of 1215 primary school-aged children (mean age 8.78 years) from three Portuguese districts (Lisbon, Porto, Coimbra) were assessed during 2016/2017. Father and mother's education (low, medium, high) and work status (employed, unemployed/retired) were used as SEP indicators. Self-reported HRQoL was assessed with the KIDSCREEN-27. Height and weight were objectively measured and body mass index categorized in normal, overweight or obese. Age, sex, and district-adjusted linear regression models were fitted to estimate associations between SEP indicators and HRQoL dimensions, according to weight status. RESULTS: We found that 24.9% of children were categorized as having overweight/obesity. The mean scores of the Physical Well-Being, and School Environment dimensions of HRQoL were lower among children classified with overweight/obesity compared to children with normal weight (57.21 vs 54.11, P < .001 and 57.85 vs 56.04, P = .010, respectively). Father's education was significantly associated with all HRQoL dimensions in children with a normal weight, but the same was not observed among children presenting overweight/obesity. An increase in the level of maternal education was also significantly associated with all HRQoL dimensions among children classified with a normal weight, and only for the School Environment dimension among children classified with overweight/obesity. CONCLUSIONS: These results suggest the presence of socioeconomic inequalities in self-reported HRQoL from early age, particularly among children with normal weight.

Time trends and social inequalities in child malnutrition: nationwide estimates from Brazil's food and nutrition surveillance system, 2009-2017.

OBJECTIVE: In Brazil, national estimates of childhood malnutrition have not been updated since 2006. The use of health information systems is an important complementary data source for analysing time trends on health and nutrition. This study aimed to examine temporal trends and socio-demographic inequalities in the prevalence of malnutrition in children attending primary health care services between 2009 and 2017. DESIGN: Time trends study based on data from Brazil's Food and Nutrition Surveillance System. Malnutrition prevalence (stunting, wasting, overweight and double burden) was annually estimated by socio-demographic variables. Prais-Winsten regression models were used to analyse time trends. Annual percent change (APC) and 95 % CI were calculated. SETTING: Primary health care services, Brazil. PARTICIPANTS: Children under 5 years old. RESULTS: In total, 15,239,753 children were included. An increase in the prevalence of overweight (APC = 3·4 %; P = 0·015) and a decline in the prevalence of wasting (-6·2 %; P = 0·002) were observed. The prevalence of stunting (-3·2 %, P = 0·359) and double burden (-1·4 %, P = 0·630) had discrete and non-significant reductions. Despite the significant reduction in the prevalence of undernutrition among children in the most vulnerable subgroups (black, conditional cash transfer's recipients and residents of poorest and less developed areas), high prevalence of stunting and wasting persist alongside a disproportionate increase in the prevalence of overweight in these groups. CONCLUSIONS: The observed pattern in stunting (high and persistent prevalence) and increase in overweight elucidate setbacks in advances already observed in previous periods and stresses the need for social and political strategies to address multiple forms of malnutrition.

Trends in mortality due to non-communicable diseases in the Brazilian adult population: national and subnational estimates and projections for 2030.

BACKGROUND: Monitoring and reducing premature mortality due to non-communicable diseases (NCDs) is a global priority of Agenda 2030. This study aimed to describe the mortality trends and disability-adjusted life years (DALYs) lost due to NCDs between 1990 and 2017 for Brazil and to project those for 2030 as well as the risk factors (RFs) attributed deaths according to estimates of the Global Burden of Disease Study. METHODS: We analyzed cardiovascular diseases, chronic respiratory diseases, neoplasms, and diabetes, and compared the mortality rates in 1990 and 2017 for all of Brazil and states. The study used the definition of premature mortality (30-69 years) that is used by the World Health Organization. The number of deaths, mortality rates, DALYs, and years of life lost (YLL) were used to compare 1990 and 2017. We analyzed the YLL for NCDs attributable to RFs. RESULTS: There was a reduction of 35.3% from 509.1 deaths/100,000 inhabitants (1990) to 329.6 deaths/100,000 inhabitants due to NCDs in 2017. The DALY rate decreased by 33.6%, and the YLL rate decreased by 36.0%. There were reductions in NCDs rates in all 27 states. The main RFs related to premature deaths by NCDs in 2017 among women were high body mass index (BMI), dietary risks, high systolic blood pressure, and among men, dietary risks, high systolic blood pressure, tobacco, and high BMI. Trends in mortality rates due to NCDs declined during the study period; however, after 2015, the curve reversed, and rates fluctuated and tended to increase. CONCLUSION: Our findings highlighted a decline in premature mortality rates from NCDs nationwide and in all states. There was a greater reduction in deaths from cardiovascular diseases, followed by respiratory diseases, and we observed a minor reduction for those from diabetes and neoplasms. The observed fluctuations in mortality rates over the last 3 years indicate that if no further action is taken, we may not achieve the NCD Sustainable Development Goals. These findings draw attention to the consequences of austerity measures in a socially unequal setting with great regional disparities in which the majority of the population is dependent on state social policies.

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, age-standardized 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.

Prevalence trends of overweight, obesity, diabetes and hypertension among Brazilian women of reproductive age based on sociodemographic characteristics.

The authors estimated the prevalence and trends of overweight, obesity, diabetes and hypertension among Brazilian women of reproductive age. A time series was constructed with Vigitel data from 2008 to 2015 and we analyzed trends of the prevalence of these conditions, considering sociodemographic characteristics. We observed an increasing trend in prevalence of overweight, obesity, and diabetes (for some sociodemographic characteristics), and stationary trends for hypertension. Our results highlight the need for early interventions in lifestyle of this population to reduce the NCDs risk factors burden and potentially contribute to improve maternal and neonatal outcomes and reduce the NCDs load.

Lower limb wounds in diabetic and non-diabetic patients: survival analysis. / Feridas em membros inferiores em diabéticos e não diabéticos: estudo de sobrevida.

OBJECTIVE: To evaluate the survival of wounds in lower limbs of diabetic and non-diabetic patients. METHOD: Retrospective cohort study of patients with lower limb ulcers treated at a specialized center between 2011 and 2013. Outcome: healing of lower limb injuries in days. The survival function of lower limb wounds and the differences between diabetic and non-diabetic were analyzed. The Log-rank test was used to compare the survival curves between the study groups. RESULTS: In up to 600 days, 23% of the diabetic patients presented wound healing, while 63% of the non-diabetic patients had their wounds healed, with a statistically significant difference in survival curves in comparison between the groups. The Hazard Ratios (RH) of healing were lower for diabetic patients (HR = 0.13, 95% CI = 0.02-0.97). CONCLUSION: The results show that there is a delay in wound healing in diabetic patients.

Early-life nutritional status and metabolic syndrome: gender-specific associations from a cross-sectional analysis of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).

OBJECTIVE: In the present study we investigated gender-specific associations of low birth weight (LBW) and shorter relative leg length with metabolic syndrome (MetS) after adjusting for sociodemographic characteristics and health-related behaviours. We also investigated whether these associations are independent of age at menarche and BMI at 20 years old. DESIGN: Cross-sectional analysis. SUBJECTS: Baseline data from 12 602 participants (35-74 years) of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), 2008-2010. SETTING: MetS was defined according to the revised National Cholesterol Education Program Adult Treatment Panel III guidelines. LBW (<2·5 kg) and age- and sex-standardized relative leg length (high, medium and low) were the explanatory variables studied. The strength of the associations between the explanatory variables and MetS was estimated by Poisson regression with robust variance. RESULTS: MetS prevalence was 34·2 %; it was more prevalent in men (36·8 %) than in women (32·2 %). In multivariate analysis, LBW was associated (prevalence ratio; 95 % CI) with MetS only in women (1·28; 1·24, 1·45). Shorter leg length was associated with MetS in both men (1·21; 1·09, 1·35 and 1·46; 1·29, 1·65 for low and medium lengths, respectively) and women (1·12; 1·00, 1·25 and 1·40; 1·22, 1·59 for low and medium lengths, respectively). Additional adjustments for age at menarche and BMI at 20 years old did not change the associations. CONCLUSIONS: Poor nutritional status as estimated by LBW and lower leg length in childhood was associated with a higher prevalence of MetS, although LBW was a significant factor only among women.

Evaluation of non-attendance for Pap test through the Surveillance System by telephone survey. / 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.

Sweetened Soft Drinks Consumption Is Associated with Metabolic Syndrome: Cross-sectional Analysis from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).

OBJECTIVE: To estimate the association between regular consumption of sweetened soft drinks, natural fruit juice, and coconut water with metabolic syndrome (MetS). METHODS: This was a cross-sectional study including men and women aged 35-74 years from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) Study, excluding patients with type 2 diabetes. The main explanatory variables were beverage consumption and the outcome variable was metabolic syndrome (Adult Treatment Panel III). RESULTS: After adjustments, a daily intake of 250 ml of soft drink increased the chance of metabolic syndrome (odds ratio [OR] = 1.95; 95% confidence interval [CI], 1.60-2.38). There was no association between coconut water and MetS. Moderate consumption of fruit juices has low odds of MetS compared to no consumption. CONCLUSION: Our results add evidence to potential negative effects of sweetened soft drinks on cluster metabolic abnormalities in middle-income countries.

Total and central obesity in elderly associated with a marker of undernutrition in early life - sitting height-to-stature ratio: A nutritional paradox.

OBJECTIVES: The purpose of this study was to investigate whether sitting height-to-stature ratio (SHSR) is associated with total and central obesity in the elderly. METHODS: This was a cross-sectional study with 133 noninstitutionalized elderly. High SHSR (≥ 1SD above the mean) was used as a marker of undernutrition (MU) in early life. Poisson's multiple regression was used to determine the association between variables. RESULTS: The prevalence of high SHSR was 21.0%, total obesity 43.6% and central obesity 50.4%. Elderly with high SHSR presented a statistically significant association with total obesity (PR 1.50; 95% CI 1.04-2.18) and central obesity (PR 1.42; 95% CI 1.03-1.95) after adjustment for sex, age, educational level and income in the multivariate analysis. CONCLUSION: The occurrence of total and central obesity in the elderly was associated with a MU in early life. This result indicates that nutritional deficiencies in childhood may increase the risk of obesity in the elderly, a nutritional paradox.

Factors associated with the incidence of pressure ulcer during hospital stay.

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 a taxa de incidência de úlcera por pressão e verificar fatores associados a essa ocorrência em uma coorte de pacientes hospitalizados. MÉTODO: Trata-se de estudo de coorte no qual o desfecho foi a ocorrência da úlcera por pressão. A estimativa do efeito das variáveis para a proporção de incidência acumulada do desfecho foi realizada utilizando o modelo de riscos proporcionais de Cox. A seleção das variáveis ocorreu por meio do teste de hipóteses Logrank. RESULTADOS: A amostra foi composta de 442 adultos, com 25 casos incidentes de úlcera por pressão. Pacientes com altos escores na escala de Braden apresentaram maior risco de incidência de úlcera por pressão quando comparados com aqueles classificados na categoria de baixo escore. CONCLUSÃO: Os resultados reforçam a importância do uso da Escala de Braden para auxiliar na identificação dos pacientes com maior probabilidade de desenvolver úlcera por pressão.

Genetic determinants of cardiometabolic risk factors in rural families in Brazil.

OBJECTIVES: The purpose of this study was to estimate the heritability of genetic and environmental correlations between cardiometabolic risk factors in extended pedigrees. METHODS: The Jequitinhonha Community Family Study Cohort (JCFSC) consists of individuals aged ≥18 years living in rural villages. Family pedigrees were constructed of the cohort. The following data were collected: demographic and socioeconomic status, lifestyle variables, anthropometrics, and lipid traits. RESULTS: The JCFSC consists of 931 individuals distributed into 69 pedigrees with 4,907 members in total. The heritabilities were 0.47 for total cholesterol (TC), 0.44 for triglycerides (TG) and 0.42 for high-density lipoprotein cholesterol (HDLc), 0.49 for metabolic syndrome, approximately 0.60 for anthropometric traits and 0.30 for blood pressure/hypertension. Significant genetic correlations (ρg ) were found mainly between TG and TC (ρg = 0.58) and hypertension and TG (ρg = 0.52). Systolic blood pressure (SBP) was correlated with TG (ρg = 0.39) and HDLc (ρg = -0.30). Diastolic blood pressures correlated with TG (ρg =0.56) and TC (ρg =0.30). Genetic correlations were also found between anthropometric traits, including: body mass index (BMI) and TG (ρg =0.34), waist circumference (WC) and TG (ρg =0.42), and WC and HDLc (ρg =-0.33). Household effects were found for HDLc (c(2) = 0.19), SBP (c(2) = 0.14) and Hypertension (c(2) = 0.14). CONCLUSIONS: To some phenotypes, including lipids, hypertension, blood pressure, and anthropometric traits, genetic contribution is important in the determination of cardiometabolic risk factors. This study provides a foundation for future studies. These will mainly focus on rare variants that could describe the genetic mechanisms influencing cardiometabolic risk. Am. J. Hum.

Factors associated with nutritional outcomes in the mother-child dyad: a population-based cross-sectional study.

OBJECTIVE: To estimate factors associated with double burden of nutritional outcomes in the mother-child dyad at the household level (child stunting and/or maternal overweight). DESIGN: Cross-sectional study using the Brazilian Demographic and Health Survey. Nutritional outcomes were: mother with normal weight and child with normal height; overweight mother and child with normal height; mother with normal weight and short-stature child; and overweight mother and child with short stature (double burden). The child was classified as short when height-for-age Z-score was <-2 and the mother as overweight when BMI was ≥25·00 kg/m2. Socio-economic status, environment, social vulnerability, maternal characteristics and the child's food intake were the exposure factors. The hierarchical approach for multinomial logistic regression modelling was used to assess the associations. SETTING: National Demographic and Health Survey of Children and Women conducted in Brazil, 2006-2007. SUBJECTS: Mother-child dyads (n 3676). RESULTS: After adjustments, lower maternal educational level (OR=3·53; 95 % CI 1·33, 9·33) and inadequate household (non-masonry house; OR=2·54; 95 % CI 1·39, 4·66) were associated with the double burden of malnutrition. Mother's short stature (OR=3·41; 95 % CI 1·76, 6·61), child's vegetable intake on less than or equal to 4 d/week (OR=2·21; 95 % CI 1·03, 4·75) and inadequate household (non-masonry house; OR=2·29; 95 % CI 1·36, 3·87) were associated with child's short stature. The lack of breast-feeding (OR=2·00; 95 % CI 1·07, 3·72) was associated with maternal overweight. CONCLUSIONS: The present findings contribute to establishing strategies promoting health and healthy diets, by considering the growth deficit and overweight/obesity concomitantly.

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

BACKGROUND: 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. METHODS: 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. RESULTS: 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. DISCUSSION: 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. CONCLUSION: 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.

Heritability of phenotypes associated with glucose homeostasis and adiposity in a rural area of Brazil.

We aimed to estimate the heritability and genetic correlation between glucose homeostasis and adiposity traits in a population in a rural community in Brazil. The Jequitinhonha Community Family Study cohort consists of subjects aged ≥18 years residing in rural areas in Brazil. The data on the following traits were assembled for 280 individuals (51.7% women): body mass index (BMI), body fat percentage, waist and mid-upper arm circumferences, triceps skinfold, conicity index, insulin, glucose, high-density lipoprotein cholesterol (HDLc), triglycerides and C-reactive protein. Extended pedigrees were constructed up to the third generation of individuals using the data management software PEDSYS. The heritability and genetic correlations were estimated using a variance component method. The age- and sex-adjusted heritability values estimated for insulin (h(2) = 52%), glucose (h(2) = 51%), HDLc (h(2) = 58%), and waist circumference (WC; h(2) = 49%) were high. Significantly adjusted genetic correlations were observed between insulin paired with each of the following phenotypes; (BMI; ρg = 0.48), WC (ρg = 0.47) and HDLc (ρg = -0.47). The homeostasis model assessment of insulin resistance (HOMA-IR) was genetically correlated with BMI (ρg = 0.53) and HDLc (ρg = -0.58). The adjusted genetic correlations between traits were consistently higher compared with the environmental correlations. In conclusion, glucose metabolism and adiposity traits are highly heritable and share common genetic effects with body adiposity traits.

p16 (CDKN2A) SNP rs11515 was not associated with head and neck carcinoma.

Head and neck squamous cell carcinoma (HNSCC) is considered a serious public health problem in many countries. Recently, genetic variations have been considered as important factors to cancer susceptibility and prognosis. More specifically, genetic polymorphisms have been associated with the development and prognosis of HNSCC. The purpose of the current study was to investigate an association among p16 (CDKN2A) gene polymorphism at rs11515, age, and HNSCC aggressiveness. PCR-RFLP analysis was used to investigate the p16 (CDKN2A) gene in 96 patients with HNSCC and in 100 individuals without HNSCC. A case group was categorized by age in younger (<60 years) and older (≥ 60 years) patients. Differences between the case and control groups were determined using Fisher and chi-squared tests. Time of survival was calculated from the date of diagnosis to the date of last follow-up visit or to the date of death using the Kaplan-Meier estimator and comparing this to the log-rank test. Statistical significance was set at p<0.05. In the present study, no association was established between HNSCC and rs11515 polymorphism, as indicated in a previous study. We found that HNSCC individuals with large-sized tumors and with metastatic disease presented worse overall survival, consistent with fundamental concepts that establish the effects of tumor size and lymph node metastasis to HNSCC outcomes. This study identified that there is no difference in the distribution of rs11515 between the control and HNSCC groups. In addition, no differences between rs11515 genotypes and clinicopathological parameters were observed.
