The reliability and validity of a physical activity and sedentary behaviour home audit tool for children aged 2–5 years

ObjectivesTo test the reliability and validity of a physical activity and sedentary behaviour home environment audit tool for young children (2–5 years old).DesignCross-sectional.MethodsParents of children aged 2–5 years were recruited through online methods (i.e., social media and blogs). Reliability of the SPACES home audit tool was assessed using self-reported surveys (n = 55) completed on two separate occasions, approximately 12 days apart. Validity of the home audit tool was assessed in a separate sample via home observations by researchers conducted after parents completed the self-report survey (n = 21). The audit tool measured indoor and outdoor home environment characteristics hypothesised to influence young children's physical activity and sedentary behaviour. Data were analysed using intraclass correlations (ICCs) and Kappas.ResultsThe majority of items demonstrated acceptable reliability and validity (80.4% and 53.4%, respectively). Size of the child's bedroom showed substantial agreement for reliability (ICC = 0.85), and slight agreement for validity (ICC = 0.23). Physical activity equipment items within the indoor environment showed slight to moderate agreement for reliability (ICC = 0.32–0.68) and slight agreement for validity (ICC = 0.15–0.35). Screen time equipment showed substantial agreement for reliability (ICC = 0.83) and fair for validity (ICC = 0.38). Outdoor items (e.g., backyard size, availability and condition of physical activity equipment, outdoor features) showed substantial agreement for reliability and validity (ICC = 0.84–0.95).ConclusionsThe home audit tool was found to be reliable and valid for many items. This tool could be used in future research to understand the impact of the home environment on young children's physical activity and sedentary behaviour.     

Associations between physical activity,medical costs and hospitalisations in older Australian women: Results from the Australian Longitudinal Study on Women’s Health

Objectives

The aim was to examine the associations between level of physical activity (PA) and non-hospital medical costs, and between physical activity and hospitalisations in older women from 1999 to 2013.

The Current State of Teleradiology Across the United States: A National Survey of Radiologists’ Habits,Attitudes, and Perceptions on Teleradiology Practice

PurposeTo explore the current state of teleradiology practice, defined as the interpretation of imaging examinations at a different facility from where the examination was performed.MethodsA national survey addressing radiologists’ habits, attitudes, and perceptions regarding teleradiology was distributed by e-mail to a random sample of ACR members in early 2019.ResultsAmong 731 of 936 respondents who indicated a non-teleradiologist primary work setting, 85.6% reported performing teleradiology within the past 10 years and 25.4% reported that teleradiology represents a majority of their annual imaging volumes; 84.4% performed teleradiology for internal examinations and 45.7% for external examinations; 46.2% performed teleradiology for rural areas and 37.2% for critical access hospitals; 91.3% performed teleradiology during weekday normal business hours and 44.5% to 79.6% over evening, overnight, and weekend hours. In all, 76.9% to 86.2% perceived value from teleradiology for geographic, after-hours, and multispecialty coverage, as well as reduced interpretation turnaround times. The most common challenges for teleradiology were electronic health record access (62.8%), quality assurance (53.8%), and technologist proximity (48.4%). The strategy most commonly considered useful for improving teleradiology was technical interpretation standards (33.3%). Radiologists in smaller practices were less likely to perform teleradiology or performed teleradiology for lower fractions of work, were less likely to experience coverage advantages of teleradiology, and reported larger implementation challenges, particularly relating to electronic health records and prior examination access.ConclusionDespite historic concerns, teleradiology is widespread throughout modern radiology practice, helping practices achieve geographic, after-hours, and multispecialty coverage; reducing turnaround times; and expanding underserved access. Nonetheless, quality assurance of offsite examinations remains necessary. IT integration solutions could help smaller practices achieve teleradiology’s benefits.     

Promoting physical activity in overweight and obese patients: counseling in primary care from Italy (Cesena, 2002–2003)

Abstract Sedentary habits and obesity are important problems in public health. The main objective of this study has been to increase motivation level and physical activity practice in overweight and obese patients, through a counseling intervention made from primary care physicians (MMG). The counseling model has been taken from the program PACE (Patient-centered Assessment and Counseling for Exercise and Nutrition). In the period May-April 2002–2003, 145 patients, with a BMI27, underwent a physical activity counseling administered by 10 primary care physicians (MMG). The main measures of outcome were the change of physical activity level and the state of change score and their related improvements; secondary measures: BMI and abdominal circumference. The median follow-up was 7 months. 103 of 145 (71%) agreed to the project; afterwards their motivation level and physical activity increased. BMI and abdominal circumference were reduced. There were no differences between subjects about studied features (sex, age, instruction, work, health). The counseling, following PACEs model, positively influenced the increase of physical activity and motivational level correlated in the patients who participated in the study project. It is necessary to do further studies to evaluate the real efficacy and to understand how this problem influences public health.
