BODY ADIPOSITY INDEX AND ASSOCIATED FACTORS IN ADULTS: METHOD AND LOGISTICS OF A POPULATION-BASED STUDY.

INTRODUCTION obesity is a public health problem that has increased considerably. Several techniques have been developed and used to measure the amount of body fat, or a combination of excess fat with some comorbidities. The Body Adiposity Index is a new method proposed to determine body fat and its validation is still limited. Methods and logistics of a population-based study reported in the literature are few, mainly multidiciplinas team. OBJECTIVE the objective was to report the proceedings of a population-based study, the denouement is the index of adiposity in adults. DESIGN the design of this study was cross-sectional, with a sample of 1085 adults aged 20-59 years living in the city of Viçosa, MG. A questionnaire was applied at home with sociodemographic, behavioral issues, health and level of physical activity. Then anthropometric and biochemical data were collected. The training for data collection involved the calibration of evaluators, being the correlation between the measurements checked by the intraclass correlation test and was adopted as the acceptable value of 0.60. RESULTS it is noted that, with the exception of assessors 1, the triceps and subscapular skin folds, and the evaluator 4, in the pectoral skinfolds and suprailiac, all other measures reached acceptable cutoff point for agreement among evaluators. CONCLUSIONS multidisciplinary research is important to understand the various factors that may be operating in health and disease process tool. Methodological and logistical aspects described in this study should be followed, which will lead to a steady decrease in research biases.

Abdominal perimeter is associated with food intake, sociodemographic and behavioral factors among adults in southern Brazil: a population-based study

OBJECTIVE The aim of this study is to investigate the abdominal perimeter determinants in adults who live in the city of Lages, SC. DESIGN A population-based cross-sectional study in adults from 20 to 59 years-old of the urban area (n=2.022). The dependent variable is the abdominal perimeter, the independent variables are: age, skin color self-reported, marital status, number of children, per capita income, education, physical activity, smoking, nutrition, self-reported diabetes mellitus, high blood pressure, body weight index. The differences between the mean perimeters were tested using ANOVA test and multiple linear regression for confounding adjustment. RESULTS The response rate was 98.2%, 52.3% were women. The mean abdominal perimeter for men was 93.66 cm (SD 13.8) and for women 92.80 cm (SD 14.5). There was a positive association of abdominal circumference with age (p.

HYPERTRIGLYCERIDEMIC WAIST PHENOTYPE AND CARDIOMETABOLIC ALTERATIONS IN BRAZILIAN ADULTS.

AIMS the present study aims to evaluate the prevalence of cardiometabolic changes according to the hypertriglyceridemic waist (HW) phenotype in Brazilian adults. METHODS it is a population based transversal study with 976 adults (n = 533 women) 20-59 years old. Phenotype was defined by triglycerides concentration (TGL) ≥ 150 mg/dl and waist circumference (WC) ≥80 cm in females and ≥ 90 cm in males. All the analyses were adjusted according to the study design and pondered by gender, age and schooling. A descriptive analysis was performed through averages and ratios; their respective confidence intervals were herein presented (CI 95%). The prevalence of cardiometabolic changes due to the presence of HW and to gender was calculated and compared by means of Pearsons chi-square test. Statistic significance level was 0.05. The probability of coronary event risk was estimated in 10 years and calculated from Framinghan score, using Kernel density graph. RESULTS no difference in phenotype prevalence between genders was observed. Higher averages in all the cardiometabolic risk factors analyzed and higher probability of evolving to a cardiovascular event in 10 years were observed in individuals with the HW phenotype. Lower HDL values were only verified in this group. CONCLUSION the HW phenotype is an important cardiovascular risk sign and allows the premature identification of individuals with higher risk, so that its use in clinical practice must be encouraged, mainly because it is a simple low cost asset.

Visceral adiposity index associated with behavioral and inflammatory parameters in adults: a population based study

INTRODUCTION the visceral adiposity index (VAI) is an indicator of fat distribution and function which is considered a predictor of cardiometabolic risk. OBJECTIVE analyze the factors associated with VAI in Brazilian adults. METHODS a cross-sectional population-based study was conducted with 854 adults, in Viçosa, MG, Brazil. A questionnaire was applied and anthropometric measurements, body composition and biochemical data were collected. Ordinal logistic regression was used to evaluate the factors associated with VAI. RESULTS the increase in percentage of fat, uric acid concentration and ultra-sensitive C reactive protein in the blood was positively associated with VAI in males. The level of physical activity in leisure was negatively associated. Among women, the increase in age, neck circumference, sitting time of more than 300 minutes, increased serum uric acid concentration and ultra-sensitive C reactive protein were associated with VAI. CONCLUSION except for age, all other factors associated with VAI are modifiable, suggesting that adopting early intervention measures that promote changes in habits and alter the risk of increased visceral adiposity and consequently the appearance of comorbidities should be encouraged.

Fatores associados e índice de adiposidade corporal (IAC) em adultos: estudo de base populacional

The objective of this study was to analyze factors associated with the body adiposity index. A population-based, cross-sectional study was conducted with 964 adults between 20 and 59 years of age, in Viçosa, State of Minas Gerais, Brazil. Household questionnaires and anthropometric measurements were applied to obtain data. Multiple analysis was performed using linear regression, adjusted for the sampling design effect. The prevalence of excess body adiposity was 36.89 (CI 30.81 to 43.43), being higher among men (48.18% - CI 39.09 to 57.34). Factors positively associated with body adiposity index were: female sex (p = 0.002); age in years (p < 0.001); those living with a partner (p = 0.022). Self-evaluation of positive health (p = 0.048) was negatively associated with the body adiposity index. The prevalence of excess body fat was high and the sex, age, marital status, health self-evaluation and dissatisfaction with body image were determinant factors to the increase in body adiposity in this population, indicating a marked risk for chronic diseases resulting from excess body fat.The objective of this study was to analyze factors associated with the body adiposity index.

Chronic joint symptoms in adults: A population-based study

OBJECTIVE To analyze factors associated with chronic joint symptoms (CJS) in adults. METHOD A population-based, cross-sectional study was performed with a sample of 1,217 adults aged between 20 and 59 years, in the city of Viçosa, in 2014. The sampling process was performed by conglomerates and sample was selected using a two-stage cluster-sampling scheme. First, 30 of the 99 census tracts of Viçosa were randomly selected using a random sampling scheme, without replacement. Household questionnaires were applied to obtain CJS data, sociodemographic conditions, behavioral factors and health status. Multivariable analysis was conducted using Poisson regression, adjusted for the sampling design effect, using the svy commands in Stata software. RESULTS Prevalence of CJS totaled 31.27%, significantly higher in women (18.45). Age ranges 40-49 (PR 1.50; 95CI 1.16-1.92) and 50-59 years (PR 1.55; 95CI 1.07-2.25); overweight (PR 1.60; 95CI 1.28-2.00); obesity (PR 1.60; 95CI 1.11-2.29); and those who self-reported performing heavy work (PR 1.27; 95CI 1.09-1.48) showed higher prevalences of CJS. CONCLUSION Women and individuals who were older, overweight and performing heavy work had a higher risk of CJS in this adult population residing in Viçosa, MG, Brazil.

Aspectos metodológicos da avaliação da qualidade da dieta no Brasil: revisão sistemática

This systematic review analyzes the methodologies of Brazilian studies that have used indices to evaluate dietary quality. A systematic search was performed of electronic databases (Lilacs, Medline, SciELO and Scopus) with no restriction on the year of publication of the studies. Original, Brazilian articles were selected that assessed dietary quality using the Healthy Eating Index (HEI) or its revised versions. The descriptors were as follows: dietary quality; healthy eating index; and dietary quality index. Atotal of 45 articles were selected, of which 60% analyzed dietary quality using an instrument called the Healthy Eating Index and the rest used an index of dietary quality. Of the analyzed studies, 68.9% classified dietary quality. Most of the studies used ten items to evaluate dietary quality and were not standardized regarding methodologies. A total of 33.3% of the studies related the index to socioeconomic and demographic factors, food items and health conditions. Differences in terms of nomenclature and methodologies made it difficult to compare these studies of dietary quality.

Risk and protective factors for chronic diseases in adults: a population-based study

The article describes the relative frequency ok of risk and protective behaviors for chronic non-communicable diseases (NCDs) in adults residing in Viçosa, Brazil. A cross-section-al population-based study including 1,226 adults living in the municipality. We used a structured questionnaire containing questions sociodemographic and behavioral The risk and protection factors evaluated were: smoking, physical activity, excessive consumption of alcohol and food consumption. The proportion of risk and protection factors was calculated in the total population, according to gender, education and socioeconomic status. The studied population has a high frequency of risk factors for NCDs, such as excessive consumption of alcoholic beverages, habit of consuming whole milk, habit of eating meat with visible fat, regular consumption of soft drinks and 78.5% did not achieve the minimum recommendation for physical activity in leisure time. With regard to protective factors, 86.2% of the population reported regular consumption of fruits and vegetables, and 73%, of beans. It was found the highest frequency of risk factors in among males, in younger people and middle socioeconomic status. This population has an urgent need for public policy of municipal planning to change this current scenario.
