Abstract: there is strong evidence indicating that the environment where people live has a marked influence on physical activity. the current understanding of this relationship is based on studies conducted in developed and culturally distinct countries and may not be applicable to the context of brazil. in this respect, a better understanding of methods evaluating the relationship between the environment and physical activity may contribute to the development of new studies in this area in brazil. the objective of the present study was to briefly describe the main methods used to assess the relationship between built environment and physical activity. three main approaches are used to obtain information about the environment: 1) environmental perception; 2) systematic observation, and 3) geoprocessing. these methods are mainly applied to evaluate population density, mixed land use, physical activity facilities, street patterns, sidewalk/bike path coverage, public transportation, and safety/esthetics. in brazil, studies investigating the relationship between the environment and physical activity are scarce, but the number of studies is growing. thus, further studies are necessary and methods applicable to the context of brazil need to be developed in order to increase the understanding of this subject.

Abstract: The aim of this study was to verify validity and reliability of the scores for physical exercise in leisure (PEL), leisure and locomotion activities (LLA), and total score (TS) of the Baecke habitual physical activity questionnaire in adult males. Twenty-one students of Physical Education were evaluated. For validation, the maximum oxygen uptake (O2max) and the decrease of the heart rate in percentile (%DHR) were measured through the Cooper's 12-minute walk or run test, and an annual index of physical exercise (IPE), and a week index of locomotion activities (ILA). The reliability was verified through test-retest with interval of 45 days. The Pearson correlation coefficient, and partial correlation adjusted for age and body mass index were used for validation. The intraclass correlation and paired t-test were used for reliability. The results indicated that %DHR was correlated with LLA and TS (r = 0.47 and p = 0.030; r = 0.48 and p = 0.027, respectively). IPE was correlated with PEL and TS (r = 0.56 and p = 0.008; r = 0.46 and p = 0.036, respectively). ILA was correlated with LLA and TS (r = 0.64 and p = 0.002 and r = 0.51 and p = 0.017, respectively). There was no significant difference in PEL, LLA and TS means in test-retest. The intraclass correlations were r = 0.69; r = 0.80 and r = 0.77, respectively for PEL, LLA and TS. In conclusion, the Baecke questionnaire is valid and reliable to measure habitual physical activity in Brazilian adult men.

Cadernos de Saúde Pública , 2010, DOI: 10.1590/S0102-311X2010000900002
Abstract: this was a systematic review of studies on the reliability and validity of self-report instruments for measuring physical activity, or subjective measurements, in adolescents (10-18 years). searches were conducted in databases (medline, psycinfo, sportsdiscus, scopus, web of science, scielo, lilacs) and in the references of the retrieved articles. sixty-six studies met the inclusion criteria. the majority were from north america, with only 5 from brazil. fifty-two different instruments were identified: 42 questionnaires, 6 diaries or logs, and 4 interviews. "test-retest" reliability varied from 0.20 to 0.98; the majority (28/50) of the coefficients showed values < 0.70. validity coefficients showed wide variation (-0.13 to 0.88), with the majority (64/84) < 0.50. only 3 instruments displayed correlations > 0.70. various instruments were tested in adolescents, especially questionnaires. these instruments generally showed better "test-retest" reliability than validity.

Revista de Saúde Pública , 2008, DOI: 10.1590/S0034-89102008000400001
Abstract: objective: to assess the reliability and validity of indicators of physical activity and sedentariness obtained by means of a telephone-based surveillance system. methods: reliability and validity studies were carried out in two random subsamples (n=110 and n=111, respectively) obtained from the total sample (n=2,024) of adults (>18 years) studied by the system in the municipality of s?o paulo in 2005. studied indicators included frequency of "sufficiently active during leisure time," "inactive in four domains of physical activity (leisure, work, transportation, and housework)," and "habit of watching television for long periods." reliability was assessed by comparing results of the original telephone interview with those of another identical interview repeated after seven to 15 days. validity was assessed by comparing the results of the telephone interview with those of three 24-hour recalls (reference method) carried out in the week following the original interview. results: frequencies obtained for of the three evaluated indicators were either identical or very similar for the first and second telephone interviews. kappa coefficients ranged from 0.53 to 0.80, indicating good reliability for all indicators. in relation to the reference method, all indicators showed 80% or higher specificity, and sensitivity values were 69.7% for "watching television for long periods," 59.1% for "inactive in four domains," and 50% for "sufficiently active during leisure." conclusions: the indicators of physical activity and sedentariness included in the system seem reliable and sufficiently accurate. if kept operational in coming years, this system may provide brazil with a useful instrument for evaluating public policies aimed at promoting physical activity and controlling non-transmissible chronic diseases associated with sedentariness.
