Participants (N = 1,249, aged 20 - 65 years) wore accelerometers (Actical) for 7 days and completed an interviewer-administered physical activity recall questionnaire (IPAQ- LF) for the same period. Mean daily minutes of moderate physical activity (MPA) and moderate to vigorous physical activity (MVPA) were used in analyses. Linearity between methods was explored by regressing mean minutes of activity and Pearson’s correlations were performed. A weak association between IPAQ-LF and Actical minutes of MPA and MVPA per day was shown for the whole sample (rs = 0.216 – 0.260). The magnitude of association varied between males (rs = 0.265 – 0.366) and females (rs = 0.124 – 0.167), although no obvious variations in associations were evident for parenting status. The IPAQ-LF produced substantially greater variations in estimates of physical activity than that recorded by the Actical accelerometer and large discrepancies between methods were observed at an individual level. Self-report tools provide a poor proxy of overall human movement, particularly among females. Inferences made at an individual level from self-reported data, such as intervention efficacy or health outcomes, may have substantial error.展开更多

A group of 1957 subjects 17 - 65 years of age, representative of the Kuwait population was selected using last year high school students and their relatives as well as government workers in each Kuwait governorate. Descriptive statistics, frequency tables, chi square and Fisher tests were used. ANOVA or Mann Whitney and Kruskal-Wallis tests were used for comparisons. The percentage of subjects in the low categorical PA level (from IPAQ) is high (29.4%) even at a young age (17 - 24), similar in prevalence to overweight/obesity (30%). At age 45, obesity increases to 40% with little change in % subjects of low PA. Weighted average categorical PA was 1280 MET.min/week reflecting that the majority (40%) of subjects belonged to the moderate PA category. A high proportion (38%) of subjects in the 17 - 24 age category contributed to the observed level of PA activity. Incidence of overweight and obesity increased from 30 to more than 55% from the second to the sixth decade of life. Hyperlipidemias increased in incidence from 8% to 45% of the sample from the third to the sixth decades of age. Hypertension and diabetes increased from the 4<sup>th</sup> to the 6<sup>th</sup> decades of life to affect from 14% to 40% and from 10% to 36% of the studied population, respectively. Incidence of Heart Disease increased from 9% to 15% of the sample population, between the 5<sup>th</sup> and 6<sup>th</sup> decades of life. The data indicate a sequence of events, initiated by overweight and obesity as early as in the 2<sup>d</sup> decade of life, followed by hyperlipidemia in the 3<sup>d</sup> decade, diabetes and hypertension in the 4<sup>th</sup>, and heart disease in the 5<sup>th</sup> decade of life.

Hence, this study aimed at determining the factors that influence older people to perform physical activities. The complete IPAQ （International Physical Activity Questionnaire） was applied to a population-based sample consisting of 364 elderly persons in the city of Botucatu, SAo Paulo, Brazil. Days of physical activity performed by the older people were considered by taking into account household and leisure activities. Models for count data were fitted by including socio-demographic variables as well as those related to life satisfaction. It was shown that housework physical-activity performance is associated with female, who predominantly showed to be more active in all levels. Male seemed to be more predisposed to perform lighter recreation, sports and leisure-time physical activities, such as walking. Additionally, poor schooling showed to he decisive for not performing physical activities both at home and during leisure.展开更多
