Objective: To gather the available scientific evidence about the oral health of migrants in south-south contexts. Methods: A scoping review methodology was applied through a comprehensive search in databases of scientific and grey literature: PubMed/Medline, Scopus, LILACS, EMBASE, Google Scholar and the International Centre for Migration, Health and Development. A descriptive analysis of the characteristics of the selected studies was conducted. Results: The search yielded 23 papers. Seventeen studies (17/23, 73.9%) were conducted on the Asian continent and 91.3% (21/23) were cross-sectional. Studies were focused on oral health problems such as dental caries and periodontal disease with diverse findings when comparing immigrants with natives. Some studies found poor oral health indexes in migrants. Migrants face barriers to dental health services. Other oral health variables addressed in the studies were oral health–related quality of life, beliefs, knowledge and practices in oral health. Determining factors related to oral health were evidenced, such as migration status, sociodemographic, cultural, psychological, living, economic and material conditions, social support, oral health practices and previous oral and general health status. Studies reported conceptual and methodological gaps and limitations that must be considered when interpreting the results. Conclusion: According to the scientific evidence, immigrant populations in south-south migratory contexts show poor oral health indicators, and this translates into social vulnerability in this group. Further research is needed to increase the scientific body about the social and contextual determinants in oral health and understanding of the social construction of this phenomenon.

Air quality monitoring favors adequate urban planning and the implementation of policies that guarantee public health. Most municipalities in Colombia lack air quality monitoring networks. Is the case of La Ceja (Antioquia), which in recent years has experienced accelerated demographic and urban growth associated with an increase in the number of vehicles, with possible atmospheric pollution effects. In response to this situation, an investigation was carried out to obtain indicative information on air quality and to learn about the population's perception of health. Low-cost devices were installed in different sectors to measure particulate matter concentrations up to 2.5 µg (PM2.5) for 5 consecutive months. The people in charge of the sensors filled out weekly surveys to determine the public's perception of their health status. Temporal and spatial analyses were performed with the measured data. The results suggest that, according to Colombian regulations, the predominant category for 24-hour averages of PM2.5 is good (84%). However, in some specific events such as the New Year's holidays (2021), the highest concentrations of this pollutant with acceptable category were observed, associated with the use of gunpowder. The perception of the health status of the participants in the study is good (91%). These results raise the possibility that this type of citizen networks can be used as support for environmental management and public health in intermediate municipalities., El monitoreo de la calidad del aire favorece una adecuada planificación urbana y la implementación de políticas que garanticen la salud pública. La mayoría de los municipios de Colombia carecen de redes de monitoreo de calidad del aire. Es el caso de La Ceja (Antioquia), que ha presentado en los últimos años un acelerado crecimiento demográfico y urbanístico asociado al incremento del parque automotor con posibles efectos de contaminación atmosférica. Atendiendo a esta situación, se desarrolló una investigación para obtener información indicativa sobre la calidad del aire y conocer la percepción de la salud que tiene la población. Se instalaron en diferentes sectores dispositivos de bajo costo que midieron concentración de material particulado de hasta 2.5 µg (PM2.5) durante 5 meses consecutivos. Para conocer la percepción ciudadana del estado de salud, las personas, que tenían a su cargo los sensores diligenciaron encuestas semanales. Con los datos medidos se realizaron análisis temporales y espaciales. Los resultados sugieren que, de acuerdo con la normatividad colombiana, la categoría predominante para promedios de 24 horas de PM2.5 es buena (84%). Sin embargo, en algunos eventos puntuales como las fiestas de fin de año (2021) se observaron las mayores concentraciones de este contaminante con categoría aceptable, asociadas al uso de pólvora. La percepción del estado de salud que tienen los participantes en el estudio es buena (91%). Estos resultados plantean la posibilidad que este tipo de redes ciudadanas puedan ser usadas como apoyo para la gestión ambiental y la salud pública en municipios intermedios.

This study explored the general and oral health perceptions in the Venezuelan immigrant population in Medellín (Colombia) and its conditioning factors. A qualitative study involving Venezuelan immigrants ≥18 years with a minimum stay of six months in Colombia was conducted. Dentists, dental students, and other health professionals also participated. Semi-structured interviews (n = 17), focus groups (n = 2), and key informants’ interviews (n = 4) were utilized. The interviews and focus groups were recorded and transcribed for later narrative content analysis. A high degree of vulnerability of participants was found due to the precarious living conditions from the premigratory moment and the lack of job placement possibilities at the time of settling in Colombia, where the migratory status played a fundamental role. Among the perceived needs, the mitigation of noncommunicable diseases stood out. Poor mental health symptoms (depression and anxiety) were perceived, and oral health was not a priority. Barriers to accessing health and dental care were found. The migrant condition was found to be a determinant that affected physical, mental, and oral health and the provision of health care. This situation is of interest to the construction of public health policies that guarantee access to fundamental rights.

Potato (Solanum tuberosum) is one of the most widespread crops in the Nariño area, in Colombia, and constitutes a significant asset set in the livelihood strategy adopted by the farming households. However, the challenges faced by this crop may limit the household’s assets base, making them vulnerable. This research provides a livelihood study that follows the approach proposed by the Department for International Development (DFID). Considering this conceptual framework, quantitative data were obtained through 769 surveys implemented to potato-farming households (previously classified as micro, small and medium producers), from 21 municipalities in Nariño. The results indicate that 1. The population is potato crop dependent, 2. The assets examined differ among micro, small and medium producers, 3. Cultural and traditional aspects such as community and collective work in the minga (Ayni) or seed exchange are in decline and 4. Socioeconomic and agroecological assets diversity is limited. From this analysis, it is possible to conclude that urgent and timely shock measures should be implemented (for example: market price regulation strategies and social inclusion programs focused on poverty), to avoid that the potato production loses viability as a livelihood strategy for the inhabitants of this region, El cultivo de la papa (Solanum tuberosum) es uno de los más extendidos en el departamento de Nariño, en Colombia y constituye un conjunto de activos importante en la estrategia de medios de vida adoptada por los hogares productores. No obstante, los desafíos que enfrenta este cultivo pueden limitar la base de activos de estos hogares y, por consiguiente, hacerlos más vulnerables. Esta investigación plantea un estudio de medios de vida siguiendo el enfoque del Departamento para el Desarrollo Internacional (DFID). Teniendo en cuenta este marco conceptual, se obtuvieron datos cuantitativos derivados de la aplicación de encuestas a 769 hogares productores de papa en 21 municipios del departamento de Nariño, previamente tipificados en micro, pequeño y medianos productores. Los resultados indican que 1. La población depende en gran medida del cultivo, 2. Los activos evaluados difieren entre micro, pequeño y medianos productores, 3. Aspectos culturales y tradicionales como el trabajo comunitario y colectivo en la minga (Ayni) o el intercambio de semillas están en declive y 4. la diversidad de activos socioeconómicos y agroecológicos es deficiente. A partir del análisis realizado es posible concluir que,si no se toman medidas de choque urgentes y oportunas, como por ejemplo, la regulación de los precios de mercado y el desarrollo de programas de inclusión social dirigidos a reducir la pobreza, la producción de papa pierde viabilidad como estrategia de medio de vida para los pobladores de esta región
