Conceptual and Evidence Update on Incidental Physical Activity: A Scoping Review of Experimental and Observational Studies.

Promoting incidental physical activity (IPA) can help reduce sedentary lifestyles and physical inactivity levels in the population. However, there is heterogeneity in the definition of IPA, and studies have yet to synthesize the empirical findings on this topic. This review aimed to (1) Synthesize the definitions of the IPA used in the scientific literature, (2) Identify the behaviors part of the IPA, and (3) Synthesize the main findings on IPA.

The Impact of the COVID-19 Pandemic on the Labor Market in Argentina: The Intersection of Gender and Socioeconomic Background.

This paper investigates gender differences in the short- and longer-term impacts of the COVID-19 pandemic on employment status in Argentina. Using individual cross-sectional and panel data from household surveys, we compare employment status (inactive, unemployed, self-employed, or employed, distinguishing between the formal and informal sectors) before, immediately after, and a year after the pandemic. We examine how gender intersects with education and age in affecting employment status transitions and the extent to which COVID-19 deepened gender, educational, and age inequalities.

The Gendered Impact of the COVID-19 Pandemic on Employment in Argentina: The Mediating Role of the Public vs. Private Sectors.

This study examines the COVID-19 pandemic's immediate and long-term impact on Argentina's labor market with a focus on gender disparities and the mediating role of the public vs. private sectors. Using household survey data, we assess men and women's employment trends before, during, and after the pandemic.

Oral Health Policy and Research Capacity: Perspectives From Dental Schools in Africa.

Introduction And Aims: The prioritisation of oral health in all health policies in the WHO African region is gaining momentum. Dental schools in this region are key stakeholders in informing the development and subsequent downstream implementation and monitoring of these policies. The objectives of our study are to determine how dental schools contribute to oral health policies (OHPs) in this region, to identify the barriers to and facilitators for engaging with other local stakeholders, and to understand their capacity to respond to population and public health needs.

Exploring the Association Between Detention Conditions, Detention-Related Abuse, and Mental Health Among Deported Mexican Migrants.

Migration, detention, and deportation are often rife with violence. This study sought to examine associations between pre-migration experiences, detention conditions, and mental health among Mexicans deported from the U.S.

Geographic dispersion and racial disparities in homeownership among Puerto Ricans.

The U.S. mainland Puerto Rican population has experienced dramatic growth and geographic dispersion in recent decades.

The next phases of the Migrante Project: Study protocol to expand an observatory of migrant health on the Mexico-U.S. border.

Background: Mexican migrants traveling across the Mexico-United States (U.S.) border region represent a large, highly mobile, and socially vulnerable subset of Mexican nationals.

Forest bathing and hiking benefits for mental health during the COVID-19 pandemic in Mediterranean regions.

Forest bathing (FB) has evidenced positive effects on individuals' mental health and well-being, but its benefits have mainly been studied in Asian biomes. The present study aimed to evaluate whether its benefits are also generalisable to other forests and biomes of the world, such as the Mediterranean. Eighty-six healthy adults of the general population were assessed before and after a FB near Barcelona (Spain) during the COVID-19 pandemic.

Agreement between two photoplethysmography-based wearable devices for monitoring heart rate during different physical activity situations: a new analysis methodology.

Wearables are being increasingly used to monitor heart rate (HR). However, their usefulness for analyzing continuous HR in research or at clinical level is questionable. The aim of this study is to analyze the level of agreement between different wearables in the measurement of HR based on photoplethysmography, according to different body positions and physical activity levels, and compared to a gold-standard ECG.

COVID-19 testing, infection, and vaccination among deported Mexican migrants: Results from a survey on the Mexico-U.S. border.

Background: Migrants detained and held in immigration and other detention settings in the U.S. have faced increased risk of COVID-19 infection, but data on this population is scarce.

Nativity differentials in first births in the United States: Patterns by race and ethnicity.

Background: While recent decades have seen gradual convergence in ethno-racial disparities in completed fertility in the United States, differences in the age pattern of first births remain. The role of nativity has not been fully understood.

Objective: This paper examines how first births vary by nativity, and how this variation contributes to more significant racial and ethnic differentials.

Resonance frequency is not always stable over time and could be related to the inter-beat interval.

Heart Rate Variability Biofeedback (HRVB) is based on breathing at an optimal rate (or resonance frequency, RF) corresponding to the respiratory sinus arrhythmia (RSA). Our aim is to check whether the RF is a stable factor and analyse the HRV parameters individually per each breathing rate, comparing it with free slow breathing. A sample of 21 participants were trained in a test-retest HRVB protocol.

Can HRV Biofeedback Improve Short-Term Effort Recovery? Implications for Intermittent Load Sports.

As intensity and physical demands continue to rise in sport competition, faster and better recovery becomes essential. The aim of this study was to assess the effects of HRV biofeedback (HRVB) while recovering from a submaximal aerobic exercise. Ten physically-active graduate students participated in the study, which was conducted in four sessions: exercise with free-breathing recovery, first resonance frequency (RF) detection, second RF detection, and exercise applying HRVB during recovery.

mHealth technology for ecological momentary assessment in physical activity research: a systematic review.

Objective: To systematically review the publications on ecological momentary assessment (EMA) relating to physical activity (PA) behavior in order to classify the methodologies, and to identify the main mHealth technology-based tools and procedures that have been applied during the first 10 years since the emergence of smartphones. As a result of this review, we want to ask if there is enough evidence to propose the use of the term "mEMA" (mobile-based EMA).

Design: A systematic review according to PRISMA Statement (PROSPERO registration: CRD42018088136).

Continuities and Changes in the Processes of Mexican Migration and Return.

This article examines continuities and changes in the prevalence and determinants of first migration and return between Mexico and the United States. Results show a dramatic decline over time in the likelihood of migrants' making a first trip. The empirical design distinguishes processes affecting migrating cohorts from those emanating from period conditions, paying particular attention to changes in educational selectivity and the legal status of the flows.

Migration and depression: A cross-national comparison of Mexicans in sending communities and Durham, NC.

Rationale: Latino immigrants have been shown to average better health and longevity than native whites, in spite of their relative socioeconomic disadvantage. However, mental health outcomes stand in stark contrast to this epidemiological "paradox," as factors such as depression are significantly higher for Latino immigrants than other groups.

Objective: We explore the link between migration and depressive feelings using a binational random survey of Mexicans in Durham, NC and sending communities in Mexico.

Ectoparasites from some Myocastor coypus (Molina, 1782) populations (Coypus or Nutria) in Argentina.

The occurrence of ectoparasites in wild nutria is poorly understood. Fifty-five livetrapped wild nutria (Myocastor coypus) from its indigenous region were examined for ectoparasites after capture from December 2013 to December 2014. The captures came from the Buenos Aires Province, by far the area of the country most densely populated by nutria, characterized as a temperate grassland, which are prime areas for sustained agriculture.

Serology and protein electrophoresis for evidence of exposure to 12 mink pathogens in free-ranging American mink (Neovison vison) in Argentina.

Background: Basic pathologic characteristics for farmed minks were previously reported worldwide. However, its status in the wild has not been studied in detail.

Objective: Serology and electrophoresis were carried out for evidence of exposure to 12 mink pathogens on two different locations.

Abortion Legalization and Childbearing in Mexico.

In 2007 abortion was legalized in the Federal District of Mexico, making it the largest jurisdiction in Latin America, outside of Cuba, to allow women to have abortions on request during the first trimester of pregnancy. While the implications of the law for women's health and maternal mortality have been investigated, its potential association with fertility behavior has yet to be assessed. We examine metropolitan-area differences in overall and parity-specific childbearing, as well as the age pattern of childbearing between 2000 and 2010 to identify the contribution of abortion legalization to fertility in Mexico.

Perceived discrimination among Latino immigrants in new destinations: The case of Durham, NC.

This paper draws on original survey data to assess the prevalence of perceived discrimination among Latin American immigrants to Durham, NC, a "new immigrant destinations" in the Southeastern United States. Even though discrimination has a wide-ranging impact on social groups, from blocked opportunities, to adverse health outcomes, to highlighting and reifying inter-group boundaries, research among immigrant Latinos is rare, especially in new destinations. Our theoretical framework and empirical analysis expand social constructivist approaches that view ethnic discrimination as emerging from processes of competition and incorporation.

A tale of two contexts: U.S. migration and the labor force trajectories of Mexican women.

Unlabelled: Even though women have long participated in Mexico-U.S. migration studies assessing the labor market implications of international mobility for women are rare.

A methodology to quantify the differences between alternative methods of heart rate variability measurement.

This work proposes a systematic procedure to report the differences between heart rate variability time series obtained from alternative measurements reporting the spread and mean of the differences as well as the agreement between measuring procedures and quantifying how stationary, random and normal the differences between alternative measurements are. A description of the complete automatic procedure to obtain a differences time series (DTS) from two alternative methods, a proposal of a battery of statistical tests, and a set of statistical indicators to better describe the differences in RR interval estimation are also provided. Results show that the spread and agreement depend on the choice of alternative measurements and that the DTS cannot be considered generally as a white or as a normally distributed process.

Facial Video-Based Photoplethysmography to Detect HRV at Rest.

Our aim is to demonstrate the usefulness of photoplethysmography (PPG) for analyzing heart rate variability (HRV) using a standard 5-min test at rest with paced breathing, comparing the results with real RR intervals and testing supine and sitting positions. Simultaneous recordings of R-R intervals were conducted with a Polar system and a non-contact PPG, based on facial video recording on 20 individuals. Data analysis and editing were performed with individually designated software for each instrument.

Migration, Social Organization, and the Sexual Partners of Mexican Men.

We build on recent developments in social organization theory to examine the sexual partnering of Mexican men in a new area of immigrant destination. We elaborate on two levels of contextual influence: 1) how differences in social capital between sending and receiving communities affect partner formation and 2) how neighborhood social cohesion influences immigrants' behavior. Data come from an original survey conducted in Durham, NC and migrant sending communities in Mexico.

An application of fractional differintegration to heart rate variability time series.

Fractional differintegration is used as a new tool to characterize heart rate variability time series. This paper proposes and focuses in two indexes (αc and fnQ) derived from the fractional differintegration operator. Both indexes are applied to fractional Gaussian noise (fGn) and actual RR time series in order to test their behavior.
