This article describes five elementary statistics projects involving the COVID-19 data made available to the public in csv files by the Centers for Disease Control and Prevention. The first project examined data available at the beginning of the COVID surge in New York City in spring, 2020, and used the correlation coefficient to estimate the…

Structural equation models offer a valuable tool for delineating the complicated interrelationships among multiple variables, including observed and latent variables. Over the last few decades, structural equation models have successfully analyzed complete and right-censored survival data, exemplified by wide applications in psychological, social,…

Background: In Malaysia, the mortality from melioidosis infection was reported to be higher than in other infectious diseases. The research on melioidosis is still limited in Malaysia but slightly increasing. Objectives: The objective of the study was to give an overview of the study designs, statistical methods, and comparison of research in…

This article discusses the estimation of a population proportion, using the auxiliary information available, which is incorporated into the estimation procedure by a probit model fit. Three probit regression estimators are considered, using model-based and model-assisted approaches. The theoretical properties of the proposed estimators are derived…

Background: In the UK, general practitioners/family physicians receive pay for performance on management of long-term conditions, according to best-practice indicators. Method: Management of long-term conditions was compared between 721 adults with intellectual disabilities and the general population (n = 764,672). Prevalence of long-term…

Emerging pandemics call for unique health communication and education strategies in which public health agencies need to satisfy the public's information needs about possible risks while preventing risk exaggeration and dramatization. As a route to providing a framework for understanding public information behaviors in response to an emerging…

Purpose: Reduced intensity is a hallmark of speech production in Parkinson's disease (PD). Previous work has examined the perception of intensity in PD to explain these speech deficits. This study reports loudness ratings of pure tones by individuals with PD and controls, all with normal thresholds for older adults. Method: Twenty individuals with…

Objective: Children's health beliefs are significantly related to their adherence; however, pediatric literature has rarely tested health-related theories as a whole. The goal of the present study was to evaluate the use of the health belief model (HBM) in understanding children's adherence, both globally and to individual treatment components.…

Because of their efficiency and ability to keep many other factors constant, twin studies have a special appeal for investigators. Just as with any teaching dataset, a "matched-sets" dataset used to illustrate a statistical model should be compelling, still relevant, and valid. Indeed, such a "model dataset" should meet the…

We aim to provide insight into the cause-specific mortality of older adults with intellectual disability (ID), with and without Down syndrome (DS), and compare this to the general population. Immediate and primary cause of death were collected through medical files of 1,050 older adults with ID, 5 years after the start of the Healthy Ageing and…

Background: Barriers to health care service utilization contribute to the spread of sexually transmitted infections (STIs) among teens. School-based STI screening programs reach adolescents outside of the clinic-based health care model and schools with school-based health centers (SBHCs) may expedite treatment because of their proximity to the…

Objective: This study explored maternal knowledge of pertussis and Tdap vaccine and the use of a Tdap Vaccine Information Statement (VIS) to improve that knowledge. Design: Prospective cohort study. Setting: Two outpatient obstetric clinics at a US academic medical centre. Methods: An electronic survey was administered to pregnant women who…

A retrospective data analysis using 2000-2008 three state Medicaid Analytic eXtract was conducted to examine the prevalence and association of comorbidities (psychiatric and non-psychiatric) with healthcare utilization and expenditures of fee-for-service enrolled adults (22-64 years) with and without autism spectrum disorders (International…

Objective: This study is a randomized trial of a Web-based intervention to increase condom use among college women. Participants: From October 2012 to March 2013, N = 422 completed baseline questionnaires and intervention procedures. n = 216 completed 3-month follow-up. Methods: Participants completed a decisional balance exercise examining their…

Background: Public school children regularly participate in school-based physical activity, physical education, and fitness testing. However, almost 2 million American children are homeschooled. The purpose of this research was to assess the body composition of elementary school-aged homeschool children and their corresponding cardiovascular…
