An overview of scientific-based knowledge on sedentary behaviour among the pediatric population – A conceptual model development

Author: Salomé Aubert

Abstract

Sedentary behaviour has been identified as a specifically deleterious personal practice on multiple levels of health of individuals at all ages, including the pediatric population (i.e., 0 to 18 years of age). The aims of this paper are to (I) summarize the literature concerning the definition, the characteristics, the context, the determinants and the consequences of sedentary behaviour among children and youth; (II) propose a conceptual model that summarizes these findings; and finally (III) highlight research gaps in the literature. Sedentary behaviours are common and complex behaviours that can potentially affect the health of children and youth on the physiological and psychological levels. Those deleterious effects on health can vary depending on how they are accumulated throughout the day, for example with or without interruption, or in which context. While childhood engagement in sedentary behaviours is too high in the majority of countries where it has been assessed, developing research and policies that target the reduction of sedentary behaviours among children and youth must be ranked as a top priority for all public health organizations worldwide. Although further research is needed concerning the identification of the specific determinants and consequences of different types and patterns of sedentary behaviours in various contexts, the Conceptual Model for the Study and Understanding of Children and Youth’s Sedentary Behaviour, which I have proposed in this paper, gives an overview of the topic and supports the development of policy and further research.

An Interdisciplinary Population Health Approach to the Radon Health Risk Management in Canada

Authors: Selim M. Khan, James Gomes

Abstract

Radon is a known carcinogen found in indoor air that exists at higher than the federal reference level (200 Bq/m3) in about 10% of Canadian homes. Every year, over 3,000 people die from radon-induced lung cancer, which accounts for 16% of annual lung cancer deaths in Canada. Radon is the leading cause of lung cancer deaths among non-smokers and is second among smokers. Children, women, and smokers from lower income groups are disproportionately affected. Although the Federal Government has reset the guideline (from the previous 600 Bq/m3 down to 200 Bq/m3) and provincial governments revised the building codes to limit exposure, there remain controversies with the latest scientific development in adopting strategies of radon management in Canada.

This review applies an Integrated Population Health Framework to look at the relationships and interactions between population health determinants such as biology and genetics, environment and occupation, and social and economic factors, that influence the health risk of radon. The evidence gathered supports policy analysis with the application of ethical and risk management principles that lead to the identification of efficient and affordable broad-based and population-level preventive strategies. The final inferences enhance the framework by adding critical intervention modalities to Health Canada’s National Radon Program.

Addressing the Social Determinants of Health: Actions from the City

Social determinants of health are the social, economic, and environmental factors that influence health and well-being. Social determinants influence health as they define the extent of resources and opportunities that can be made available to individuals, given their social location (Marmot & Wilkinson, 2005; Raphael, 2009). They explain the health disparities observed among individuals and represent an important and continuing public health concern within the health promotion and health services spheres of research.

Healthcare in Cuba: Defining Features and Future Trends

In 2016, Cuba made headlines for the status of its economic embargo with the US, its increasing foreign investments through tourism, and the death of Fidel Castro. Besides these recent events, in a sense foreshadowing Cuba’s future political and economic paths, throughout the 20th century, Cuba’s healthcare system has been acclaimed as one of the best healthcare systems in the world with very good health outcomes for the Cuban people. For example, infant mortality is lower than in the US and the life expectancy is 77.5 years of age (WHO, 2016). What are the Cuban healthcare system’s defining features? Will recent events alter some of its key aspects?

Conflict and disease: A complex relationship

Author: Robert A. Frank 

Societies will always be subjected to situations that test their tolerance thresholds. When a stressor exceeds a society’s capacity to cope, “failure” of the system is often manifested as social unrest, falling along a spectrum of intensity ranging from civil wars and revolutions to riots, strikes, and protests (Braha, 2012). The conflict leading to social unrest is most often initiated by groups on the disadvantaged end of systemic inequalities, as a desperate effort at effecting change (Haas, 1986). Although social unrest is sometimes a necessary vehicle for cultural revolution, the resultant disruption of society invariably creates a volatile environment that is vulnerable to adverse health outcomes (Jovanović, Renn, & Schröter, 2012).

Finding Potential in Another Mother’s Breastmilk

In Canada, the primary cause of mortality in infancy and long-term disability in children is being born at very low birth weight (<1500g or <3.3lbs; Saigal & Doyle, 2008). If these infants are fed their mother’s milk in the neonatal intensive care unit (NICU) they experience fewer severe infections (Hylander, Strobino, & Dhanireddy, 1998; Patel et al., 2013), improved feeding tolerance (Schanler, Shulman, & Lau, 1999; Sisk, Lovelady, Gruber, Dillard, & O’Shea, 2008), lower colonization of pathogenic bacteria (Yoshioka, Iseki, & Fujita, 1983), and increased neurocognitive development (Anderson, Johnstone, & Remley, 1999). However, due to many reasons related to preterm birth, as many as 70% of mothers cannot provide a sufficient amount of breastmilk to meet the demands of these infants, therefore, a supplement is necessary (Callen & Pinelli, 2005). Currently in Canada, either pasteurized donor breastmilk (donor milk) or preterm formula is used as a supplement to mother’s milk.

Planning and delivery of health services – an article review on urban aboriginal mobility in Canada: examining the association with healthcare utilization

Author: Ankit Dhawan

Abstract

An article from Social Science and Medicine, written by Snyder and Wilson (2012), examined the use of healthcare services by urban Aboriginal populations in Canada. Using the Behavioural Model of Health Services Use (BMHSU), predisposing, enabling, and need factors were organized and used for data analysis. Specifically, a comparison was made between conventional (physicians and nurses) and traditional (traditional healers) health service utilization in Toronto and Winnipeg. In addition to the geographical and educational factors, the results of the research recognized mobility as a significant predisposing complement to healthcare utilization.

An Overview of the Malaria Epidemic in Sub-Saharan Africa

Author: Sandra M. Konji

Abstract

Malaria is a parasitic disease that is transmitted by mosquitos during their blood meal. The risk of contracting malaria is highest for people in tropical countries, due to the ever-present humid weather that allows yearly infections. Consequently, sub-Saharan Africa has a disproportionately higher rate of death among women and children with malaria. One of the major barriers identified in the efficacy of malaria treatment and prevention is the lack of health education and literacy. The lack of health education has decreased the efficacy of antimalarial drugs, such as Artemether Lumefantrine, due to the distribution and administration of the drug by untrained persons. The lack of incidence and prevalence data makes it difficult to ensure adequate supply of the drug in endemic countries. Furthermore, the lack of knowledge of malaria pathogenesis and transmission has prevented many from promptly seeking treatment and practicing preventative care methods. Recently, the implementation of health education programs by international organizations has allowed local and travelling healthcare practitioners to be educated on the disease and methods of antimalarial drug administration.

The Development of Scoring Criteria for a New Picture Naming Task

Authors: Ferzin MahavaChristine SheppardLaura MonettaVanessa Taler

Abstract

Objective: The purpose of the study was to develop a scoring system for a novel naming task suitable for assessing naming performance in younger (18-30 years) and older (65+ years) adults in monolingual English, monolingual French, and English-French bilingual groups. This novel naming task will serve as an important health service to help diagnose and assess cognitively impaired older individuals, while also serving as an educational tool for healthcare providers.

Materials and Methods: The Naming Task consists of 120 images organized in the same randomized order, and are shown on a white background displayed on a computer screen using PowerPoint. Participants are instructed to name the image displayed. Monolinguals completed the test in their native language and bilinguals completed the test in English only, French only, and a bilingual administration. Scoring criteria was established based on the responses from testing.

Results: Strict and lenient scoring criteria developed for the Naming Task are presented. Eight items were removed from the original Naming Task due to quality and/or clarity, inability to name the image, or too many alternate responses. Performance in mono-lingual English and French was similar in younger and older adults for strict and lenient scoring. Bilinguals performed better with bilingual administration and worse with French administration, where scores were the lowest of all age and language groups.

Conclusion: The Naming Task appears to be suitable for monolingual French and English individuals. Results suggest that a bilingual administration should be used when testing English-French bilinguals.

Transmission of Human Papillomavirus Without Sexual Contact

Authors: Naweed Ahmed, Wakqas Kayani, Sahab Jamshidi, Suneil Bapat, Ahmed ImamovicPanteha Tavassol

Abstract

Human papillomavirus (HPV) is one of the most common sexually transmitted infections. There are four common HPV strains: 6, 11, 16, and 18. Strains 6 and 11 cause genital warts, while strains 16 and 18 are asymptomatic in males and may progress to cervical cancer in females. Although uncommon, a small percentage of males and females have been diagnosed with HPV without previous sexual contact. In this case report, we discuss a case conducted on a 15-year-old South Asian male who contracted an unknown low-risk strain of HPV with no history of sexual contact. HPV is highly infectious, however in the majority of cases the immune system is able to clear the infection, preventing the appearance of genital warts. In cases such as these, it is important to help control the spread of viral infections. Several determinants of health are involved in and affect the trans-mission of HPV, including income and social status, social support networks, education and literacy, culture, social and physical environments, and health services. To aid in the prevention of HPV, sexual education should be taught at early ages within schools and the Gardasil® vaccine should be administered to both females and males at an early age to reduce the burden of disease and the incidence of HPV.
