International physical activity questionnaire overestimation is ameliorated by individual analysis of the scores.

Sedentarism is considered a risk factor for coronary heart disease and death from any cardiovascular disease. The International Physical Activity Questionnaire (IPAQ) assesses physical activity in metabolic equivalents, using 4 dimensions: occupation, transportation, household activities, and leisure-time physical activity. The purpose of this investigation was to assess physical activity levels in the patients enrolled in the Maracaibo City Metabolic Syndrome Prevalence Study, currently undertaken by the "Dr. Félix Gómez" Endocrine-Metabolic Research Center. Two thousand one hundred eight individuals were recruited and subjected to a standard Medical chart, Graffar scale, and IPAQ long form, applied by trained personnel. Description of the population was done using mean, SD, and coefficient of variation. IPAQ scores were analyzed as medians and distributed by percentiles. From the 2108 individuals, 46.9% were men and 53.1% were women. The most prevalent physical activity was high physical activity with 39.9%, followed by moderate physical activity with 36.9% and low physical activity with 23.2%. Medians for each IPAQ dominion were occupation with 0.00 (0.00-66.00), transportation with 165.00 (0.00-463.00), household activities with 772.50 (0.00-2520.00), and leisure time with 0.00 (0.00-594.00). Using leisure-time scores, a new reclassification was conducted, obtaining 1245 subjects with 0 metabolic equivalents in this dominion. From this new subsample, 43.6% had High physical activity, 56.95% had Moderate physical activity, and 91% had Low physical activity, demonstrating an important overestimation in the former sample results. IPAQ overestimates moderate and vigorous activity in the adult population of the Maracaibo Municipality. Overestimation is mainly located in the household- and gardening-related activity.

Epidemiologic behavior of obesity in the Maracaibo City metabolic syndrome prevalence study.

INTRODUCTION: Obesity is a worldwide public health issue. Since the epidemiological behaviour of this disease is not well established in our country, the purpose of this study was to determinate its prevalence in the Maracaibo City, Zulia State- Venezuela. MATERIALS AND METHODS: A cross-sectional study was undertaken using the data set from the Maracaibo City Metabolic Syndrome Prevalence Study. The sample consists of 2108 individuals from both genders and randomly selected: 1119 (53.09%) women and 989 (46.91%) men. The participants were interrogated for a complete clinical history and anthropometric measurements. To classify obesity, the WHO criteria for Body Mass Index (BMI), and Waist Circumference (WC) from the IDF/NHLBI/AHA/WHF/IAS/IASO-2009 (IDF-2009) and ATPIII statements were applied. RESULTS: For BMI, obesity had an overall prevalence of 33.3% (n = 701), and according to gender women had 32.4% (n = 363) and men had 34.2% (n = 338). Overweight had a prevalence of 34.8% (n = 733), Normal weight had 29.8% (n = 629), and Underweight had 2.1% (n = 45). Adding Obesity and Overweight results, the prevalence of elevated BMI (>25 Kg/m(2)) was 68.1%. Using the IDF-2009 WC's cut-off, Obesity had 74.2% prevalence, compared to 51.7% using the ATPIII parameters. CONCLUSIONS: These results show a high prevalence of abdominal obesity in our locality defined by the WHO, IDF-2009 and ATPIII criteria, which were not designed for Latin-American populations. We suggest further investigation to estimate the proper values according to ethnicity, genetic background and sociocultural aspects.
