Background
To ensure accurate measurement of the health benefits of habitual physical activity in large sample epidemiological studies, physical activity questionnaires (PAQs) are the most feasible methods. Therefore, the purpose of this study was the validation and cultural adaptation to the Hungarian population of the International Physical Activity Questionnaire (IPAQ-HL).
Methods
A cross-sectional study among Hungarian healthy adults (age 21.375 ± 1.940 years,
n
= 120) was performed comparing measures of last 7 days IPAQ-HL self- administered questionnaire and obtained accelerometer (Actigraph GT3X) data for concurrent validity, reassessed by a random subsample (
n
= 33) to measure reliability.
Results
Our results indicate acceptable criterion validity for total physical activity, moderate to vigorous physical activity (
R
= 0.387,
p
< 0.001;
R
= 0.331
p
< 0.001 respectively) and moderate physical activity (
R
= 0.193,
p
= 0.034). The ICC scores revealed moderate to good correlations (ICC = 0.744–0.942,
p
< 0.001). Moderate Kaiser–Meyer–Olkin measure (0.531,
p
< 0.001) and good reproducibility for vigorous, moderate to vigorous and moderate activities was found for IPAQ-HL in the studied population. Nevertheless, like analogous self-reports in other languages, it overestimates the time spent on physical activity.
Conclusions
IPAQ-HL proved to be a reasonably valid measure for population prevalence epidemiological studies and is suggested for use to develop public health policy recommendations or to optimize public health interventions. However, the results on vigorous activity should be interpreted with caution, the questionnaire showed moderate validity for this particular intensity.
Background: It is well known that physical activity (PA) has health benefits. This study aimed to examine physical activity carried out by the senior (over 50) participants and its relation to their quality of life (QoL). Methods: Surveillance of PA and QoL was measured by using questionnaires (GPAQ, WHOQoL-BREF) in this study. Descriptive data were presented as means and standard deviations (SD) for continuous variables and as percentages for categorical variables. Multivariate linear regression analysis was conducted. The significance level was set at p ≤ 0.05. Results: Overall, 250 participants were recruited, the mean age of the study population (n = 243) was 70.2 (SD 7.1) years. The results clearly showed that the Hungarian participants aged over 50 years were more likely to do PA if they had university degree and lower age (p ≤ 0.001) and used more active transportation (p = 0.035) if they had low education. The results of WHOQoL-BREF showed that the Hungarian individuals have better QoL if they have university degree (p ≤ 0.001) and lower age (p ≤ 0.001). Using multivariate linear regression analysis to examine the effect of PA patterns on QoL adjusted for demographic variables (age, education, BMI, place of living), the result showed significant correlation between WHOQoL-BREF dimensions and GPAQ (p ≤ 0.001). Conclusion: Higher amount of PA among aging population can result in better QoL in all dimensions.
