Estudo transversal e analítico que identificou estado nutricional, padrões alimentares e nível de atividade física em 276 adolescentes, com idade de 14 a 17 anos. O estado nutricional foi avaliado pelo Índice de Massa Corporal e a medida da Circunferência da Cintura. Para avaliar o consumo e as práticas alimentares, foi aplicado um questionário adaptado da Pesquisa Nacional de Saúde do Escolar, de 2009. O nível de atividade física foi classificado de acordo com o International Physical Activity Questionnaire. Encontravam-se eutróficos 89,9% desta população e 27,2% apresentavam risco para doenças cardiovasculares. Foram identificados quatro padrões alimentares: saudável; ultraprocessado; cafeteria; ambiente escolar. Pertenciam ao padrão saudável 62,5% dos adolescentes com excesso de massa corporal e 56,2% dos adolescentes com risco cardiovascular. A maioria encontrava-se no nível de atividade física, que oferece menor risco para doenças cardiovasculares, independente dos padrões alimentares. Contudo, dados fornecidos na construção dos padrões alimentares e de inatividade reforçam a percepção de que esta população pode estar suscetível a doenças cardiovasculares na idade adulta, se mantiver as práticas atuais.

Background: Physical inactivity is considered as a major independent modifiable risk factor for chronic diseases and is one of the most important causes of obesity. Considering the increasing prevalence of chronic diseases in India, the physical activity plays an important role. Taking this into consideration we conducted a study to assess the physical activity levels using the global physical activity questionnaire among obese and non-obese individuals. Methods: A cross sectional study was conducted among adults 20-60 years age-group in rural and urban field practice areas of a medical college in Puducherry by simple random sampling method to select 237 individuals from each area. The level of physical activity was analysed using the global physical activity questionnaire. Results: Among the study population, 61.39% belong to low physical activity level. Among 97 obese individuals, 53.61% belong to low physical activity and no statistical significance was noted between the levels of physical activity and obesity. The prevalence of obesity was 36.13% among those who reported walking and bicycle usage and statistical significance was noted among obese and non-obese individuals (p<0.001). Statistical significant difference was observed in duration of physical activity (minutes/day) among obese and non-obese individuals. Conclusions: The prevalence of obesity seems to be lower among the people who practice simple day-to-day habits such as walking and usage of bicycles as evidenced from our study. Such simple and replicable behavioural modifications need to be brought about at a societal level, if we want to minimise the danger of the looming obesity epidemic.

Abstract Background Self-reported physical activity is inaccurate, yet few investigators attempt to adjust for measurement error when estimating risks for health outcomes. We estimated what the association between self-reported physical activity and colorectal cancer risk would be if physical activity had been assessed using accelerometry instead. Methods We conducted a validation study in which 235 Australian adults completed a telephone-administered International Physical Activity Questionnaire (IPAQ), and wore an accelerometer (Actigraph GT3X+) for 7 days. Using accelerometer-assessed physical activity as the criterion measure, we calculated validity coefficients and attenuation factors using a structural equation model adjusted for age, sex, education and body mass index. We then used a regression calibration approach to apply the attenuation factors to data from the Melbourne Collaborative Cohort Study (MCCS) to compute bias-adjusted hazard ratios (HR) and 95% confidence intervals (CI). Results Average daily minutes of physical activity from the short form of the International Physical Activity Questionnaire (IPAQ-short) were substantially higher than accelerometer-measured duration (55 versus 32 min). The validity coefficient (0.32; 95% CI: 0.20, 0.43) and attenuation factor (0.20; 95% CI: 0.12, 0.28) were low. The HRs for colorectal cancer risk for high (75th percentile; 411 min/week) versus low (25th percentile; 62 min/week) levels of self-reported physical activity were 0.95 (95% CI: 0.87, 1.05) before and 0.78 (95% CI: 0.47, 1.28) after bias adjustment. Conclusions Over-estimation of physical activity by the IPAQ-short substantially attenuates the association between physical activity and colorectal cancer risk, suggesting that the protective effect of physical activity has been previously underestimated.

Aim: The aim of the study was to evaluate the level of declared physical activity of first-year students from Jozef Pilsudski University of Physical Education in Warsaw by using the International Physical Activity Questionnaire (IPAQ). The paper presents physical activity according to the students’ chosen degree course and sex. The study also analyzes physical activity in relation to the BMI index according to the classification by the World Health Organization (WHO). Basic procedures: The group of participants comprised 190 Physical Education (n = 115) and Sports (n = 75) students. The study was conducted in November 2015 and used the short version of the International Physical Activity Questionnaire. Main findings: The results of the present study showed that the physical education students were characterized by a higher level of physical activity in each discussed type of physical activity than their peers studying sports. The study also revealed that the women showed greater physical activity than the men. It was only in vigorous-intensity physical activity that the men obtained higher results than the women. Conclusions: The male first-year students of the University of Physical Education in Warsaw prefer vigorous-intensity physical activity, and the female students prefer both moderate-intensity activities and walking. With the development of sports infrastructure and the growing number of sports services, women have become more physically active and achieve results rivaling, or at times, surpassing the results obtained by men.

This study aimed to analyze the level of physical activity for people with high blood pressure cared for in a health center. This cross-sectional study was conducted with 310 individuals between 18 and 69 years of age through the International Physical Activity Questionnaire (IPAQ). The majority (80%) of participants presented low or moderate levels of physical activity. The analysis of association between sociodemographic variables and physical activity level revealed that older men from the interior of the state with higher educational levels have a greater chance of exhibiting lower levels of physical activity. The logistic regression model revealed that origin, schooling and diabetes are predictors of low physical activity level. The conclusion is that part of the sample does not match the desirable profile to practice regular physical activity.

Abstract Background: This study aims to investigate the reliability and validity of the Turkish version of the Brunel Lifestyle Physical Activity Questionnaire (BLPAQ) and examine the cultural adaptation of the questionnaire.Methods: After the translation process, the test-retest reliability of the Turkish version of the questionnaire was analyzed with 24 (31.20±5.0 years old; 50% female) participants (2nd test was done 15 days after the first test). In addition, the validity of the scale was evaluated by the correlation between the BLPAQ and the International Physical Activity Questionnaire Short Form (IPAQ-SF) completed by 113 (30.59±5.40 years old; 63.7% Female) participants.Results: A powerful positive and significant correlation was found between the correlation coefficients of the BLPAQ's PPA and UPA subscales between both tests (respectively r=0.96, p<0.01; r=0.87, p<0.01). The Cronbach's alpha coefficient was found to be 0.77 (quite reliable). The PPA subscale of the BLPAQ was positive with the IPAQ-SF's high-intensity physical activity subscale (r=0.47 p=0.00) and total IPAQ-SF excluding sitting (r=0.50 p=0.00) medium in the direction and low positive correlation with the walking activity subscale (r=0.25 p=0.024). No significant correlation was found between the UPA subdivision of BLPAQ and IPAQ-SF (p>0.05).Conclusion: BLPAQ, adapted into Turkish, is a valid and reliable tool that can be used to determine lifestyle according to physical activity level.
