The governance of migratory flows, understood as a system of co-management co-responsibility between institutional and private, political and social actors with respect to their identity and occupational health is addressed in the present non-experimental, exploratory and cross-sectional work with a non-probabilistic sample selection of 100 former migrants from central Mexico. From a structural model seven factors were established regarding framing, demands, resources, risks, opportunities, capabilities and employment. Based on the literature consulted, the limits, scope and lines of research aimed at deepening the effects of the variables and factors in an intercultural scenario are noticed.


Quantitative researchers need a probabilistic sample to generalise their findings, but research constraints often compel them to use non-probabilistic samples. The use of non-probability sampling methods in quantitative studies has therefore become a norm. Interestingly, even studies published in top-quality journals compromise best practices that the use of non-probabilistic samples requires. Based on a thorough review of relevant studies, we developed a typology of non-probability sampling methods used in quantitative health studies. An attempt was made to discuss the limit of inference under each type of non-probability sampling method. Non-probability sampling in quantitative research was also delineated as a way to maximise response rate. This study is expected to guide students and early career epidemiologists to understand how to apply non-probabilistic sampling methods in quantitative approaches and plausibly document or report their chosen methods.

ABSTRACT Objective: To understand the differences of physicians, nurses, and social workers in the evaluation of the health status of the elderly. Methods: A cross-sectional quantitative study, using descriptive statistics. Non-probabilistic sample, consisting of 291 participants from three professional categories: 71 (24.4%) physicians, 192 (66%) nurses, and 28 (9.6%) social workers. We used a questionnaire including the variables: sociodemographic characteristics and instruments used for evaluation. Results: Instruments with greater utility for the evaluation of the elderly: for physicians, Mini Mental State Examination; for nurses, Braden scale; and for social workers, genogram. In the physical examination, the data most collected by physicians and nurses are the vital signs; and by social workers, the condition for performing the Activities of Daily Living. Conclusions: The evaluation of the elderly is based on a diversity of instruments and is an area in which health and social professionals need to share information.

ABSTRACT Objectives: to estimate the prevalence of stunting and thinness and sociodemographic, household, family, dietary, and scholar associated factors in schoolchildren living in Lokossa-Benin. Methods: a survey conducted in a probabilistic sample (n=615) of primary schoolchildren (8-17 years), from 12/2018 to 01/2019, using structured questionnaire and 24-hour dietary recall. Thinness and stunting were defined as Height-for-age and Body Mass Index-for-age below-2 standard deviations, respectively. Associations were estimated by chi-square test and logistic regression. Results: thinness and stunting prevalence was 13.1% (95%CI:9.0-18.7) and 25.5% (95%CI:20.6-31.2), respectively. Odds of thinness were higher among older schoolchildren and those who experienced hunger at school. Odds of stunting increased with age, low diet diversity, experiencing hunger at school, and having school meal five days a week (OR:2.09; 95%CI:1.29-3.36). Conclusions: stunting was the most common problem. Older schoolchildren and those with food deprivation or poor diet diversity were the most affected.

The objective of this study was to explore the acculturation strategies present in the ethnic groups in the internal migration process in Peru, from the self-perception of social well-being and psychological acculturation, as conflict prevention factors. The study methodology was non-experimental and cross-sectional, comprising a non-probabilistic sample of 214 migrants of Quechua ethnic origin residing in Lima and Callao. The results indicated that just over half of the participants perceive themselves as integrated or assimilated to the host society. The results of the research show the prevalence of acculturation strategies linked to social welfare, where internal immigrants of Quechua origin and language seek integration into the environment that enables the performance of roles in the public and private spheres that facilitate adaptation processes and minimization of conflicts.

This article has to relate invisible discrimination with diversity in students in university classrooms, whose variable is invisible in nature, with tendencies to distort objective reality, thus causing discriminated young people to have socio-emotional instability in their lives. Quantitative, descriptive correlational study and due to the sensitivity of the subject, a non-probabilistic sample was taken for convenience of 290 students from the different academic programs; The data collection instrument was a questionnaire, the results were found using Pearson's Correlation Coefficient, which indicates that there is a partial relationship between diversity and invisible discrimination (p = 0.45).

In undergraduate students, it is not uncommon to hear that they have symptoms of anxiety, due to the workload they have. Objectives: Identify the presence of anxiety in FPyTCH students, Indicate if academic performance is affected with respect to anxiety in FPyTCH students. Methodology: This research was non-experimental, exploratory, observational, by survey, cross-sectional and descriptive, since no experimental maneuver was performed, in a non-probabilistic sample obtained by accident and convenience, after signing the informed consent. Procedure: 104 students participated corresponding to the semesters of 1st, 2nd, 3rd, 4th and 5th, to who were administered the Beck anxiety questionnaire. For statistical processing, spss version 20.0 software was used. Contribution: .906 CRONBACH. The results obtained show that 28.8% of the students present severe anxiety and 13.5% do not have anxiety, as well as the minimum grade average found is 6.9 and the maximum is 9.7, however, said grade average is not found. influenced by the presence or not of anxiety.

Terrorism carried out by State forces is the most reprehensible action to be taken because the power and resources of a country are used to generate terror. Such power and resources are aimed at reaching certain political goals instead of serving the citizens. Transitional Justice has raised complex debates related to democratisation, human rights and the reconstruction of the State and its institutions after periods of severe social conflict. After the last military dictatorship in Argentina (1976-1983), different transitional justice mechanisms were implemented to cope with the consequences of the State’s collective violence: Truth Commission, criminal trials, institutional reforms, as well as reparatory gestures. A descriptivecorrelational study of group difference was developed, with a non-experimental cross-sectional design. It was aimed at analysing the psychosocial impact of transitional justice measures taken in Argentina. The study was conducted on a non-probabilistic sample composed of 576 participants. Findings support the effectiveness of combined Transitional Justice measures, the weakness of recognition of criminal acts and apologies, and significant differences in terms of violence affectation.

AbstractPeer violence within school coexistence exposes children and adolescents to risk and vulnerability, therefore scholar bullying is also a relevant issue on childhood well-being. In that sense, the United Nations Convention on the Rights of the Child constitutes a framework for promoting children’s well-being in schooling and education: in relation to protection rights from all forms of violence, schools should protect children from physical, mental or any other danger. The negative influence of scholar peer violence on children’s subjective well-being can be explored through the analysis of the responses given by a probabilistic sample of primary school children from Barcelona in 2017 (mean age = 10.7, analysed sample = 3,962) to the Barcelona Survey of Children’s Subjective Well-Being, an adapted version of the third wave of the International Survey of Children’s Well-Being from the Children’s Worlds international research project. It is noteworthy the negative influence of the scholar peer violence on the children’s subjective well-being, and that there are children without the personal and social support for deal with this type of adversity. Finally, some children’s interpretations and their proposals are shared to ‘taking decidedly action against bullying and preventing it’.

Abstract Background Although a trend towards dental caries reduction has been observed, further investigations on its pattern and development are still needed. Objective To investigate the influence of clinical, social and environmental variables on dental caries prevalence in adolescents from a Brazilian municipality supplied with fluoridated water in 2018. Method This study was conducted with a non-probabilistic sample of 277 adolescents aged 12 years of public schools in Nova Friburgo, state of Rio de Janeiro, Brazil. Clinical examinations were carried out by calibrated examiners to assess caries, periodontal disease, and fluorosis according to criteria of the World Health Organization (WHO). Semi-structured questionnaires were applied to record socio-environmental information. Results Individuals living in regions supplied with fluoridated water below the minimum required levels (OR=3.60, p=0.0006), with low income (OR=1.90, p=0.0444), presence of gingivitis (OR=3.36; p=0.0016), and whose reason for visiting the dentist was dental treatment (OR=2.41; p=0.0203) were more likely to have dental caries. A significant reduction (p<0.0001) in dental caries indexes was observed between 2012 and 2018. Conclusion Fluoridation of public water supply at unsuitable levels, as well as other social and clinical variables can influence the caries pattern in adolescents.
