Article Abstract

Background: This study aimed to examine the reliability and criterion validity of three physical activity questionnaires in Brazilian military soldiers.

Methods: A convenience sample of 109 male Air Force soldiers (18.86±0.36 years of age and 22.59±2.58 kg/m body mass index) completed the Brazilian Portuguese versions of the two-item PACE+, the Godin-Shepard Leisure-Time Physical Activity Questionnaire (GSLTPAQ) and the Baecke's Habitual Physical Activity Questionnaire (BHPAQ) twice (day one and six weeks after), for test-retest purposes. The criterion validity of these measures was assessed against the soldiers' cardiorespiratory fitness performance by Cooper's 12-minute run test.

Results: The intraclass correlation coefficient (ICC) results indicated excellent reliability for the BHPAQ (ICC=0.85) and moderate to good reliability for the PACE+ and GSLTPAQ (ICC=0.50 and 0.63, respectively). The Bland-Altman plots demonstrated good agreement and lower bias for the PACE+ and the BHPAQ (mean differences = 1.01 and -0.06, respectively). The significant correlations with the cardiorespiratory fitness levels were only observed for PACE+ (ρ=0.22), BHPAQ sports dimension (ρ=0.29), and BHPAQ total (ρ=0.24) scores.

Conclusions: The BHPAQ showed to be the most suitable of these three self-report physical activity questionnaires for use in these military personnel, revealing higher test-retest reliability and criterion validity.

Eating disorders are primarily associated with women and an obsession with thinness. Recent research and social media content show that men are also concerned about their body image, striving for a muscular and athletic physique. To investigate eating disorder tendencies among male content creators with a mesomorphic body type (N = 26), a social media analysis was conducted on Instagram and TikTok over four weeks.

Background: The benefits of physical activity for frail older acutely hospitalized adults are becoming increasingly clear. To enhance opportunities for physical activity on geriatric wards, it is essential to understand the older adult's perspective.

Aim: The aim of the study was to explore the experiences and perceptions of physical activity among older adults during hospital stays on a geriatric ward.

Background: Physical inactivity, impaired physical mobility and poor mental health are common in the older population and increasing as the population ages. We examined the relationships between physical activity, physical mobility, and mental health in the general population of older adults.

Methods: The study is based on 12 959 men and women aged 70 years or older answering a survey questionnaire sent to a random population sample in Mid-Sweden in 2022 (response rate 66%).

Background: Parkinson's disease (PD) is characterized by motor symptoms altering gait domains such as slow walking speed, reduced step and stride length, and increased double support time. Gait disturbances occur in the early, mild to moderate, and advanced stages of the disease in both backward walking (BW) and forward walking (FW), but are more pronounced in BW. At this point, however, no information is available about BW performance and disease stages specified using the Hoehn and Yahr (H&Y) scale.

Background: Preschools are important environments in shaping young children's lifestyle behaviours, including movement (physical activity, screen time, and sleep) and eating behaviours. Few studies have investigated how teachers and principals can be supported in promoting healthy lifestyle behaviours in the preschool setting and whether a digital support tool could be a way forward. This study aimed to explore preschool teachers' and principals' perceptions, needs, and prerequisites for promoting healthy lifestyle behaviours, as well as their preferences for a potential digital support.
