ObjectivesPrevious studies of the association between physical activity and adiposity are largely based on physical activity and body mass index (BMI) from questionnaires, which are prone to inaccurate and biased reporting. We assessed the associations of accelerometer-measured and questionnaire-measured physical activity with BMI, waist circumference and body fat per cent measured by bioelectrical impedance and dual-energy X-ray absorptiometry (DXA).DesignCross-sectional analysis of UK Biobank participants.SettingUK Biobank assessment centres.Participants78 947 UK Biobank participants (35 955 men and 42 992 women) aged 40–70 at recruitment, who had physical activity measured by both questionnaire and accelerometer.Main outcome measuresBMI, waist circumference and body fat per cent measured by bioelectrical impedance.ResultsGreater physical activity was associated with lower adiposity. Women in the top 10th of accelerometer-measured physical activity had a 4.8 (95% CI 4.6 to 5.0) kg/m2lower BMI, 8.1% (95% CI 7.8% to 8.3%) lower body fat per cent and 11.9 (95% CI 11.4 to 12.4) cm lower waist circumference. Women in the top 10th of questionnaire-measured physical activity had a 2.5 (95% CI 2.3 to 2.7) kg/m2lower BMI, 4.3% (95% CI 4.0% to 4.5%) lower body fat per cent and 6.4 (95% CI 5.9 to 6.9) cm lower waist circumference, compared with women in the bottom 10th. The patterns were similar in men and also similar to body fat per cent measured by DXA compared with impedance.ConclusionOur findings of approximately twofold stronger associations between physical activity and adiposity with objectively measured than with self-reported physical activity emphasise the need to incorporate objective measures in future studies.

Prevalence Of Obesity

Lack of physical activity among adolescents is one of the factors which lead to the accumulation of body fat and increase prevalence of obesity among Malaysian population. Therefore, this study was aimed to determine the association between body fat percentage and physical activity level among adolescents in Kuala Nerus, Terengganu. This cross-sectional study involved 300 participants consists of 44.7% male and 55.3% female aged between 10 to 16 years old. Anthropometric measurements included body weight, height and waist circumference. Body fat percentage (%BF) was assessed using bioelectrical impedance analysis (BIA). Physical activity was assessed by physical activity questionnaire (PAQ-C) and pedometers in a subsample (n = 50). The result shows that the mean body fat percentage and BMI of the participants were 23.02±9.41% and 20.03±4.77 kg/m2, respectively. Mean PAQ-C score and pedometer steps count for both genders were 1.9±0.42 and 6079±1878, respectively. Male has higher PA level compared to female in their daily life based on PAQ-C score and pedometer steps count. PAQ-C score and pedometer step counts were negatively associated with %BF however there is no significant association between screen time and %BF. As a conclusion, the problems of obesity can be solved by providing strategies to promote active living among adolescents in Malaysia not only focus on increasing physical activity but also emphasise reduction in sedentary behaviours.

Abstract Background Physical inactivity is associated with an increased risk of major chronic diseases, although uncertainty exists about which chronic diseases, themselves, might contribute to physical inactivity. The objective of this study was to compare the physical activity of those with chronic diseases to healthy individuals using an objective measure of physical activity. Methods We conducted a cross-sectional analysis of data from 96 706 participants aged 40 years or older from the UK Biobank prospective cohort study (2006–10). Diagnoses were identified through ICD 9 and 10 coding within hospital admission records and a cancer registry linked to UK Biobank participants. We extracted summary physical activity information from participants who wore a wrist-worn triaxial accelerometer for 7 days. Statistical analyses included computation of adjusted geometric means and means using general linear models. Results Participants with chronic disease undertook 9% or 61 minutes (95% confidence interval: 57.8–64.8) less moderate activity and 11% or 3 minutes (95% confidence interval: 2.7–3.3) less vigorous activity per week than individuals without chronic disease. Participants in every chronic-disease subgroup undertook less physical activity than those without chronic disease. Sixty-seven diagnoses within these subgroups were associated with lower moderate activity. Conclusions The cross-sectional association of physical activity with chronic disease is broad. Given the substantial health benefits of being physically active, clinicians and policymakers should be aware that their patients with any chronic disease are at greater health risk from other diseases than anticipated because of their physical inactivity.

This study evaluated the effects of physical exercise on cardiovascular and psychobiological health (levels of anxiety, depression, fatigue) in university students. A cross-sectional study was conducted, including 72 students in the health care field in 2018. First, an anamnesis was conducted, with information on the eligibility criteria and the physical exercise they practice, to obtain the groups "practices physical exercise" and "no physical exercise." Among eligible individuals, anthropometric measurements were taken, heart rate variability was recorded, questionnaires on depression, anxiety, fatigue, and physical activity were applied, along with a cardiorespiratory test. Of the student participants, 45.0% were female, 20.0% were male, and 42 reported exercising, 30 did not. High levels of depression, anxiety, fatigue, and body fat percentage above adequate levels were observed in the study group. Students who practiced physical exercise had lower depression scores, lower body fat percentage, and better autonomic modulation when comparing study groups. There was no difference in cardiorespiratory fitness between practitioners and non-practitioners of physical exercise. A more active lifestyle, including the practice of regular physical activity, is a practical component in improving cardiometabolic and psychobiological profiles in university students and, therefore, should be encouraged during university life.
