This study aimed to evaluate the validity and precision of the International Physical Activity Questionnaire (IPAQ) for climacteric women using computational intelligence techniques. The instrument was applied to 873 women aged between 40 and 65 years. Considering the proposal to regroup the set of data related to the level of physical activity of climacteric women using the IPAQ, we used 2 algorithms: Kohonen and k-means, and, to evaluate the validity of these clusters, 3 indexes were used: Silhouette, PBM and Dunn. The questionnaire was tested for validity (factor analysis) and precision (Cronbach's alpha). The Random Forests technique was used to assess the importance of the variables that make up the IPAQ. To classify these variables, we used 3 algorithms: Suport Vector Machine, Artificial Neural Network and Decision Tree. The results of the tests to evaluate the clusters suggested that what is recommended for IPAQ, when applied to climacteric women, is to categorize the results into two groups. The factor analysis resulted in three factors, with factor 1 being composed of variables 3 to 6; factor 2 for variables 7 and 8; and factor 3 for variables 1 and 2. Regarding the reliability estimate, the results of the standardized Cronbach's alpha test showed values between 0.63 to 0.85, being considered acceptable for the construction of the construct. In the test of importance of the variables that make up the instrument, the results showed that variables 1 and 8 presented a lesser degree of importance and by the analysis of Accuracy, Recall, Precision and area under the ROC curve, there was no variation when the results were analyzed with all IPAQ variables but variables 1 and 8. Through this analysis, we concluded that the IPAQ, short version, has adequate measurement properties for the investigated population.

AbstractIntroductionThe International Physical Activity Questionnaire (IPAQ) was developed to measure health-related physical activity (PA) in populations. The short version of the IPAQ has been tested extensively and is now used in many international studies. The present study aimed to explore the validity characteristics of the long-version IPAQ.Subjects and methodsForty-six voluntary healthy male and female subjects (age, mean±standard deviation: 40.7±10.3 years) participated in the study. PA indicators derived from the long, self-administered IPAQ were compared with data from an activity monitor and a PA log book for concurrent validity, and with aerobic fitness, body mass index (BMI) and percentage body fat for construct validity.ResultsStrong positive relationships were observed between the activity monitor data and the IPAQ data for total PA (ρ = 0.55, P < 0.001) and vigorous PA (ρ = 0.71, P < 0.001), but a weaker relationship for moderate PA (ρ = 0.21, P = 0.051). Calculated MET-h day−1 from the PA log book was significantly correlated with MET-h day−1 from the IPAQ (ρ = 0.67, P < 0.001). A weak correlation was observed between IPAQ data for total PA and both aerobic fitness (ρ = 0.21, P = 0.051) and BMI (ρ = 0.25, P = 0.009). No significant correlation was observed between percentage body fat and IPAQ variables. Bland–Altman analysis suggested that the inability of activity monitors to detect certain types of activities might introduce a source of error in criterion validation studies.ConclusionsThe long, self-administered IPAQ questionnaire has acceptable validity when assessing levels and patterns of PA in healthy adults.

AbstractObjectiveTo modify the self-administered, short version of the International Physical Activity Questionnaire (IPAQ) for adults to be used in the elderly (aged 65 years and above), and to validate this modified IPAQ for the elderly (IPAQ-E).DesignA direct validity study using accelerometer-measured physical activity (PA) as the criterion measure, and an indirect criterion validity study using high-sensitivity C-reactive protein (hs-CRP) as a biological marker of activity.SettingOrganisations for retired persons in Sweden.SubjectsThe direct validity study consisted of fifty-four participants and the indirect criterion validity study consisted of 359 participants. All participants were retired persons (66–91 years) living independently.ResultsAll self-reported activity domains (sitting, walking, moderate and vigorous) were positively correlated with the corresponding variable objectively assessed by an accelerometer (ρ= 0·277–0·471), but a systematic error was observed. The specificity of IPAQ-E to identify low-active participants was 85 %, and the sensitivity to identify the more active participants was 81 %. A main effect of IPAQ-E category (Low, Moderate or High) was observed for hs-CRP (P= 0·041).ConclusionsWe found this modified version of IPAQ, the IPAQ-E, to be well accepted by our sample of socially active elderly. It provided acceptable estimates of PA, well in line with other questionnaires, even though it had a systematic error. The IPAQ-E was able to identify an expected response of a biomarker (hs-CRP) to PA. We recommend the use of the IPAQ-E to classify participants aged 65 years and above into PA categories, to rank individuals or to identify individuals meeting certain PA criteria.

OBJECTIVE: The aim of this study was to compare the inappropriate eating behaviors of adolescents as a function of habitual level of physical activity. METHODS: Participants were 462 youth of both genders aged 10 to 19 years. The Eating Attitudes Test-26 was used for inappropriate eating behaviors assessment. A short version of the International Physical Activity Questionnaire was used for classifying the habitual level of physical activity. RESULTS: No statistically significant differences were found for the comparison of inappropriate eating behaviors in the multivariate covariance model either for females or males. Moreover, the level of physical activity had no significant influence on the inappropriate eating behaviors of these adolescents. CONCLUSION: In conclusion, inappropriate eating behaviors in both genders were similar regardless of the habitual level of physical activity.

Objectives: Evidence indicates that regular physical activity has positive effects on the mother’s health and outcomes of pregnancy. The measurement of physical activity during pregnancy is required for planning and developing health-related interventions. The aim of this study was to evaluate the psychometric properties of the Persian version of the pregnancy physical activity questionnaire. Materials and Methods: This cross-sectional methodological study was conducted with a sample of 200 pregnant women living in Tabriz. Women with low-risk singleton pregnancies in the age range of 20-40 years were included in the study. Sampling was carried out using a multistage sampling method in healthcare centers. Exploratory factor analysis (principal component analysis with varimax rotation), multivariate analysis of variance and Pearson correlation were used for data analysis. Reliability and internal consistency of the questionnaire were assessed using a test-retest method with a 2-week interval and Cronbach’s alpha coefficient, respectively. Results: A five-factor model was developed: ‘vulnerable people’, ‘activities related to work’, ‘home’, ‘sports’ and ‘activities related to leisure time’. They accounted for 43.32% of the observed variance. The Cronbach’s alpha coefficients of the entire instrument and domains were 0.879 and 0.83-0.93, respectively. The Intra-class correlation coefficient (ICC) was equal to 0.857 (CI95% = 0.75-0.93) indicating proper stability of the questionnaire over time. Conclusions: The Persian version of the pregnancy physical activity questionnaire is a valid and reliable tool for examining the risk of physical activities among Iranian pregnant women.

Aim: To compare the short version of International Physical Activity Questionnaire (IPAQ) and the accelerometer measurement of physical activity (PA) in patients undergoing hemodialysis. Methods: Sample consisted of 40 patients (19 men) aged 45 ± 16 years. Patients reported their PA using the IPAQ during a face-to-face interview, and wore an Actigraph GT3-X accelerometer for 1 week to obtain minutes per day of light PA, moderate-to-vigorous PA (MVPA) and total PA as well as raw counts per day (vector magnitude). Results: All PA-related variables were significantly correlated among instruments (r = 0.34-0.47) when analyzed as a group. However, when analyzed separately by gender, the relationships were present for women only (r = 0.46-0.62). IPAQ significantly underestimated light PA (IPAQ vs. accelerometer: 180.0 vs. 251.1 min/day, p = 0.019), but no differences were found between methods for MVPA and total PA. Conclusion: Modest correlations were found between self-reported PA time by IPAQ (short version) and accelerometer, but only in women. However, the IPAQ may underestimate light PA, which is the main form of PA in this population.

AbstractThe aim of the study was to examine changes in objective and self-reported physical activity (PA) among women aged 60 years and older. The study included 200 women aged over 60 years, divided into three groups according to age (60–65 years, 66–70 years, > 70 years). The subjective assessment was provided with the International Physical Activity Questionnaire (IPAQ) – short version with self-reported PA assessment, and objective data was provided by an Actigraph GT3-BT worn for seven days. Significant differences in moderate and high intensity PA, moderate-to-vigorous PA and steps per day were found between the oldest and youngest groups; as well as in low, moderate, moderate-to-vigorous PA and steps per day between groups middle and oldest. In all three age groups, 1) significant differences were observed between subjective and objective measurements of physical activity and 2) no correlation was found between assessment measures. It was found that only direct PA measurement declined with age in women over 60 years old, and that sedentary behavior is underestimated, and moderate and vigorous PA overestimated, with the self-reported IPAQ.
