A nutritional survey was performed in a random sample of 550 individuals ( > or = 18 years) in Bambuí, Minas Gerais State, Brazil, using the Semi-Quantitative Food Frequency Questionnaire calibrated with 24-hour recall. Comparisons used means, proportions, and the nutrient adequacy ratio (NAR: 90.0-110.0%). Adequate intake was reported in only 2.4% of the individuals for carbohydrate, 17.6% for protein, 0.0 to 5.1% for vitamins, and 0.0 to 21.1% for minerals. NAR was influenced by gender and age: 90.2% and 91.8% of women presented low iron and B6 vitamin intake, respectively. Meanwhile, 87.7% of men reported excess iron, 80.3% phosphorous, and 11.9% cholesterol. Regarding aging, 64.3% of elderly (>or= 60 years old) reported low protein intake and 39.3% inadequate lipid fraction balance (P/S); 35.7% reported high unsaturated fatty acid intake. For adults (18-59 years), 67.8% reported excess protein and 53.4% deficient iron intake. In this population, high lipid consumption and low intake of fiber, vitamins, and minerals pose an important public health problem and may contribute to an increase in chronic non-communicable diseases.

IntroductionThe practice of physical activity is an important factor in the prevention of health problems. However, a small portion of the population is physically active. Recent reviews show that physical activity classes in community settings have the potential to increase population levels of physical activity and reduce health inequalities.ObjectiveTo evaluate the effect of the Academias da Cidade Program in Belo Horizonte on the practice of physical activity in leisure time (PALT) by non-users living near the program centers.MethodsWe conducted a home-based health survey in Belo Horizonte (2008–2009) with 1,581 adults who were non-users of the program and who lived within a 1,500-meter radius of one active program center (exposed group) and two nonoperational centers with sites reserved for their construction (unexposed group). We collected data on PALT levels (≥150 minutes/week), which was measured with the Physical Activity International Questionnaire and analyzed with binary logistic regression using the Generalized Estimating Equations method. The propensity score was used as an adjustment variable to control the potential confusion in the measures of effect of exposure studied.ResultsThe overall prevalence of the PALT was 26.5% in the exposed group and 22.7% in the unexposed group. The exposed group was more likely to be active in leisure time (OR = 1.05; CI 95%: 1.01–1.10). When considering the interaction between exposed group and distance, individuals in the exposed group who lived less than 500 meters from the program center were more likely to be active in leisure time (OR = 1.18, CI 95%: 1.03–1.35) compared to their counterparts.ConclusionPromoting physical activity in the community can favorably affect PALT levels among residents, especially those living closest to intervention centers. We believe the Academias da Cidade Program is a promising strategy to facilitate the access to appropriate spaces for the practice of physical activity and contribute to increase the levels physical activity within populations.

ResumoA epidemiologia da nutrição dispõe de uma gama de metodologias para avaliar o estado nutricional. Entretanto, os métodos dieté-ticos são os únicos capazes de detectar a deficiência nutricional em seu estágio inicial, sendo por isso bastante utilizados em estudos epidemiológicos de associação entre exposições e eventos. Atualmente, o méto-do dietético mais indicado para estudos epidemiológicos, principalmente aqueles envolvendo doenças crônico-degenerativas, tem sido o questionário semiquantitativo de freqüência alimentar (QSFA). Este instrumento, não diferente de outros, está sujeito à variabilidade e a erros de medida. Entretanto, estes podem ser identificados e tratados utilizando-se métodos como comparação de médias dietéticas, estudos de confiabilidade, de validação relativa e de calibração. Em estudo realizado em Bambuí-MG, o consumo de nutrientes foi avaliado por três diferentes métodos: QSFA e recordatórios 24 horas (R24) com e sem réplicas de alimentos, tendo suas médias comparadas e calibradas. As médias encontradas pelo QSFA foram consistentemente maiores do que as dos R24. No entanto, quando essas foram ajustadas pelo consumo calórico total não apresentaram diferenças importantes, exceto para fibras; zinco; vitaminas C; B 6 , e E; e colesterol. E as médias calibradas foram, em geral, menores do que as não calibradas, sendo estatisticamente significantes para ingestão de lipídeos; fibras; zinco; vitaminas C, E e A; ácidos graxos saturados, monoinsaturados e poliinsaturados; e colesterol.Palavras-chave: Palavras-chave: Palavras-chave: Palavras-chave: Palavras-chave: Calibração.

The Brazilian P-CPQ with three subscales and 13 items appears to be a valid short version to be used in further studies to evaluate parents/caregivers' perceptions of children's oral health-related quality of life.
