Mobile Phone-Based Measures of Activity, Step Count, and Gait Speed: Results From a Study of Older Ambulatory Adults in a Naturalistic Setting

Mobile Phone-Based Measures of Activity, Step Count, and Gait Speed: Results From a Study of Older Ambulatory Adults in a Naturalistic Setting

These instruments included the (1) functional component of the Late Life Function and Disability Instrument (LLFDI), a comprehensive assessment of function and disability for use in community-dwelling older adults that evaluates self-reported difficulty performing 32 physical activities (eg, use of a stepstool or running to catch a bus), where higher scores indicate higher functional status) [21]; (2) the Survey of Activities and Fear of Falling in the Elderly (SAFFE), a questionnaire evaluating fears associated

Using Laboratory Test Results for Surveillance During a New Outbreak of Acute Hepatitis in 3-Week- to 5-Year-Old Children in the United Kingdom, the Netherlands, Ireland, and Curaçao: Observational Cohort Study

Using Laboratory Test Results for Surveillance During a New Outbreak of Acute Hepatitis in 3-Week- to 5-Year-Old Children in the United Kingdom, the Netherlands, Ireland, and Curaçao: Observational Cohort Study

In March 2022, a series of cases of severe hepatitis in young children was recognized in Central Scotland [1]. As of August 26, 2022, a total of 1115 probable cases were reported—acute hepatitis (not caused by hepatitis A-E virus) with serum transaminase >500 U/L (aspartate transaminase [AST] or alanine transaminase [ALT]) in children aged 16 years or younger [2]. In this period, 22 children died in 35 countries [1-3] and 47 (4%) have undergone emergency liver transplants [3].

Interrupting Sitting Time in Postmenopausal Women: Protocol for the Rise for Health Randomized Controlled Trial

Interrupting Sitting Time in Postmenopausal Women: Protocol for the Rise for Health Randomized Controlled Trial

If all the preliminary screening criteria are met, participants complete a battery of cognitive tests and questionnaires on self-reported demographics and PA. Participants are given an activ PAL, a thigh-worn accelerometer that objectively measures sitting time and number of sit-to-stand transitions, and an Acti Graph GT3 X+ (Acti Graph, LLC) accelerometer, a waist-worn device that objectively measures minutes of PA.

Development and Evaluation of a Community Health Program to Promote Physical Activity Among Vulnerable Community-Dwelling Older Adults: Protocol for a Prospective Cohort Study

Moreover, regular PA can also have a positive impact on social connectedness [13], which in turn can improve older adults’ cognitive and mental health and seems to be a relevant factor in successful aging [14]. Accordingly, regular PA can be considered a beneficial investment in individual health capital [15] and in healthy aging in general [11].

Internet-Based Motivation Program for Women With Eating Disorders: Eating Disorder Pathology and Depressive Mood Predict Dropout

Internet-Based Motivation Program for Women With Eating Disorders: Eating Disorder Pathology and Depressive Mood Predict Dropout

Although the majority of studies have found a higher risk of dropout for patients with higher depression scores [29,30], this effect did not reach significance in a meta-analysis [23]. Additionally, age has been identified as a predictor of staying in treatment in bulimia nervosa because older patients tend to persist longer with face-to-face treatment than younger patients [23].

Using Crowdsourcing Technology for Testing Multilingual Public Health Promotion Materials

Using Crowdsourcing Technology for Testing Multilingual Public Health Promotion Materials

This factor should not be underestimated: according to the American Community Survey [6], 20% of the US population over 5 years of age speak a language other than English at home, and 43.8% of these have limited English proficiency, defined as having a primary language other than English and a limited ability to read, speak, write, or understand English. Two reasons why health promotion materials are often developed in a cursory manner are time and costs.

Quality Criteria for Serious Games: Serious Part, Game Part, and Balance

Quality Criteria for Serious Games: Serious Part, Game Part, and Balance

Fancy animations or a possibility to change their avatar (eg, new clothes, hair color, or equipment) as a reward for accomplishing a task can further motivate players. However, there is ample evidence that “rewards or feedback delivered in a controlling manner undermine intrinsic motivation and deeper forms of learning” [80]. Therefore, rewards should be deliberately deployed in serious games. High-quality serious games should measure the effects and benefits in a scientific study.

Incidence and Characterization of Post-COVID-19 Symptoms in Hospitalized COVID-19 Survivors to Recognize Syndemic Connotations in India: Single-Center Prospective Observational Cohort Study

Incidence and Characterization of Post-COVID-19 Symptoms in Hospitalized COVID-19 Survivors to Recognize Syndemic Connotations in India: Single-Center Prospective Observational Cohort Study

Presentations of multisystem inflammatory syndrome in children and adults show that COVID-19 negativity is not a hardtop, as there could be postinfectious complications constituting a post-COVID-19 state and its associated health issues [2]. A clear definition of what these health problems are and their magnitude is crucial to prepare an efficient, multidisciplinary service [3].
