Secular trends in BMI, excess weight and body fat skinfolds in Peruvian children living at high altitude
Positive secular trends in BMIlog and SKFlog were observed, with significant increases at specific ages
Temporal stability of behavior, temporal cue-behavior associations, and physical activity habit strength among mothers with school-aged children
Objective: PA habits reflect stable, consistent patterns in behaviours that are performed automatically in response to temporal or contextual cues. Mothers face multiple demands and complex schedules related to parenting. This study examined how subject-level mean, variability, and slopes in device-measured moderate-to-vigorous physical activity (MVPA) over three different timescales were associated with mothers’ PA habits. Methods and Measures: …
Is there an association between proficiency in fundamental movement skills and moderate‐to‐vigorous physical activity in childhood on weekdays and weekends? The React project
OBJECTIVE: The present study probes into the association between children's fundamental movement skills (FMS) and moderate-to-vigorous physical activity (MVPA) during weekdays and weekends. METHODS: This cross-sectional sample included 1014 children aged 6-10 years from the REACT project. Physical activity was assessed with accelerometry, and five FMS (stationary dribble, kick, catch, overhand throw, and underhand roll) were assessed with the dig…
Sleep and fundamental movement skills in primary schoolchildren: The React project
OBJECTIVE: Whether sleep is related to fundamental movement skills (FMS) in the pediatric population is largely unknown. The objective of this study was to examine the association between sleep characteristics (duration, efficiency, regularity) and FMS proficiency levels in school-aged children. METHODS: This cross-sectional study included 996 children (mean age: 8.3 ± 1.2 years) from 25 of the 32 primary schools in Matosinhos, northern Portugal.…
Background, rationale, and methodological overview of the React project—return‐to‐action on growth, motor development, and health after the Covid ‐19 pandemic in primary school children

In this article, our goal is to describe statistical analysis of the longitudinal ordinal motor development data that w…
Validity and reliability of Meu Educativo ®: A new tool to assess fundamental movement skills in school‐aged children
OBJECTIVES: There is evidence showing that children's proficiency in fundamental movement skills (FMS) is positively related to weight status, physical activity, fitness levels, cognitive development, as well as academic performance. Yet, the feasibility of FMS assessment is challenging, especially with relatively large samples of children. This article presents a new tool named Meu Educativo® to assess children's FMS levels, including its validi…
Associations of obesity, movement behaviors, and socioeconomic status with fundamental movement skills in children: Results from the React project
OBJECTIVE: To investigate the relationship of biological characteristics (age, sex, and obesity), movement behaviors (physical activity and sedentary time), and family socioeconomic status with fundamental movement skills (FMS) in primary school children. METHODS: This cross-sectional study sampled 1014 children (537 girls) aged 6 to 10 years from 25 primary schools in Matosinhos, north of Portugal. Five object control skills (dribbling, kicking,…
A multivariate multilevel approach to unravel the associations between individual and school factors on children's motor performance in the React project
PF and object control FMS z-scores were moderately related. Not all child characteristics were associated with both PF and object control FMS, and their effect sizes were different. School characteristics only explained 10% of the total variation in PF and object control FMS
Individual and school correlates of body mass index and cardiorespiratory fitness in primary school children from the React project: A multivariate multilevel analysis
BMI and CRF had a low but statistically significant negative correlation in this sample of children. Most of the variation in BMI and CRF was explained by child-level characteristics
Centering categorical predictors in multilevel models: Best practices and interpretation.
The topic of centering in multilevel modeling (MLM) has received substantial attention from methodologists, as different centering choices for lower-level predictors present important ramifications for the estimation and interpretation of model parameters. However, the centering literature has focused almost exclusively on continuous predictors, with little attention paid to whether and how categorical predictors should be centered, despite their…
Secular Trends in Physical Fitness of Peruvian Children Living at High-Altitude
The physical fitness of children is an important marker of health, and monitoring its temporal changes provides important information for developing interventions. We aimed to: (1) describe secular trends in physical fitness across age, within each sex, in Peruvian schoolchildren; and (2) verify if these trends are also present when adjusted for changes in height and weight. We sampled 1590 children (707 in 2009; 883 in 2019), aged 6-11 years. Ph…
Modeling the Dynamics of Children’s Musculoskeletal Fitness
This study models children's musculoskeletal fitness (MSF) developmental trajectories and identifies individual differences related to effects of time-invariant, as well as time-varying covariates. A total of 348 Portuguese children (177 girls) from six age cohorts were followed for three years. MSF tests (handgrip strength, standing long jump and shuttle run), age, body mass index (BMI), socioeconomic status (SES), gross motor coordination (GMC)…
Sibling Resemblance in Physical Activity Levels: The Peruvian Sibling Study on Growth and Health
Physical activity is associated with a host of positive health outcomes and is shaped by both genetic and environmental factors. We aim to: (1) estimate sibling resemblance in two physical activity phenotypes [total number of steps∙day -1 and minutes for moderate steps per day (min∙day -1 )]; and (2) investigate the joint associations of individual characteristics and shared natural environment with intra-pair sibling similarities in each phenoty…

Differential Influence of Parental Smoking and Friends' Smoking on Adolescent Initiation and Escalation and Smoking
Smoking-related behaviors and attitudes of significant others (especially friends and parents) are among the most consistent predictors of adolescent smoking. However, theorists remain divided on whether the behaviors of significant others influence adolescent smoking directly or indirectly, and the relative influence of parental and peer smoking on adolescents' own smoking is still a matter of debate. In addition, little research has examined th…

Participants responded to five to seven random prompts/day for 7 consecutive days; when prompted, participants rated eight mood adjectives assessing positive affect (PA) and negative affect (NA). Global depressed…
Analysis of clustered data in community psychology: With an example from a worksite smoking cessation project
Although it is common in community psychology research to have data at both the community, or cluster, and individual level, the analysis of such clustered data often presents difficulties for many researchers. Since the individuals within the cluster cannot be assumed to be independent, the use of many traditional statistical techniques that assumes independence of observations is problematic. Further, there is often interest in assessing the de…

Evaluation of the Be the Exception Sixth-Grade Program in Rural Communities to Delay the Onset of Sexual Behavior
Objectives. To investigate the impact of Be the Exception, a newly developed program to delay onset of sexual behaviors, in a White, rural population. Methods. A cluster randomized controlled trial in northwestern Indiana (14 schools, 1776 students, 2011–2015) compared an intervention (5 group sessions and multimedia assembly) with a no-intervention group; both continued usual standard health education. Multilevel mixed-effects logistic regressio…
A Random-Effects Ordinal Regression Model for Multilevel Analysis
A random-effects ordinal regression model is proposed for analysis of clustered or longitudinal ordinal response data. This model is developed for both the probit and logistic response functions. The threshold concept is used, in which it is assumed that the observed ordered category is determined by the value of a latent unobservable continuous response that follows a linear regression model incorporating random effects. A maximum marginal likel…

Application of random-effects pattern-mixture models for missing data in longitudinal studies.
Random-effects regression models have become increasingly popular for analysis of longitudinal data. A key advantage of the random-effects approach is that it can be applied when subjects are not measured at the same number of timepoints. In this article we describe use of random-effects pattern-mixture models to further handle and describe the influence of missing data in longitudinal studies. For this approach, subjects are first divided into g…
A Multilevel Thresholds of Change Model for Analysis of Stages of Change Data
In this article we describe a model for multilevel ordinal response data that allows for non- proportional odds for a subset of explanatory variables. As applied to stages of change data, which are commonly encountered in health promotion research, this model is termed the multilevel thresholds of change model since it focuses on modeling the K-I thresholds that delineate membership in the K ordered stages. Explanatory variables can have the same…
A mixed‐effects multinomial logistic regression model
A mixed‐effects multinomial logistic regression model is described for analysis of clustered or longitudinal nominal or ordinal response data. The model is parameterized to allow flexibility in the choice of contrasts used to represent comparisons across the response categories. Estimation is achieved using a maximum marginal likelihood (MML) solution that uses quadrature to numerically integrate over the distribution of random effects. An analys…

An Application of a Mixed‐Effects Location Scale Model for Analysis of Ecological Momentary Assessment (EMA) Data
For longitudinal data, mixed models include random subject effects to indicate how subjects influence their responses over repeated assessments. The error variance and the variance of the random effects are usually considered to be homogeneous. These variance terms characterize the within‐subjects (i.e., error variance) and between‐subjects (i.e., random‐effects variance) variation in the data. In studies using ecological momentary assessment (EM…
Long-Term Effects of Repealing the National Maximum Speed Limit in the United States
Objectives. We examined the long-term effects of the 1995 repeal of federal speed limit controls on road fatalities and injuries in fatal crashes. Methods. We used a Poisson mixed-regression model to assess changes in the number of fatalities and injuries in fatal crashes between 1995 and 2005 on rural interstates, where all US states have raised speed limits since the repeal, as well as on urban interstates and noninterstate roads, where many st…

A Practical Guide to Calculating Cohen’s f2, a Measure of Local Effect Size, from PROC Mixed
Reporting effect sizes in scientific articles is increasingly widespread and encouraged by journals; however, choosing an effect size for analyses such as mixed-effects regression modeling and hierarchical linear modeling can be difficult. One relatively uncommon, but very informative, standardized measure of effect size is Cohen's f(2), which allows an evaluation of local effect size, i.e., one variable's effect size within the context of a mult…
