Life Satisfaction and Influenza Vaccination Among Older Adults in Canada.

Older adults have an increased risk of complications or death from influenza. Despite the benefits of vaccination for older adults, vaccination coverage among older adults ages 65 years and over is still below Canada's national target of 80 per cent. As health-care-seeking behaviours are influenced by several factors, including life satisfaction, we investigated the relationship between life satisfaction and influenza vaccination among older adults. A sample (n = 22,424) from the 2015-2016 Canadian Community Health Survey data was analysed using descriptive and multinomial logistic regression analyses. Higher life satisfaction was associated with a more recent influenza vaccination history. Vaccination differed by gender, age, and self-reported health status, as women, much older adults, and those with the poorest health status were more likely to be vaccinated. The study suggests an association between life satisfaction and influenza vaccination. More research into the factors that impact influenza vaccination in older adults is needed to increase vaccination coverage in the older adult population.

Recency of immigration and utilization of dental care services in Canada.

OBJECTIVES: To investigate the association between recency of immigration to Canada and the utilization of dental health services. METHODS: The cross-sectional study sample (n = 2137) was drawn from the 2015-2016 Canadian Community Health Survey (CCHS). It consisted of Canadian residents aged 12 years and older who resided in the two provinces and one territory who opted into the optional dental module and gave valid responses to the questions 'How often do you usually see a dental professional, such as a dentist, a dental hygienist or a denturologist?' and 'Length of time since immigration to Canada?' for the outcome and independent variable, respectively. Multinomial logistic regression was used to analyse the data, and all statistics were weighted using sampling weights provided by Statistics Canada. RESULTS: The adjusted odds ratios were lower for recent immigrants than for established immigrants and for visits more than once per year (OR = 0.35; 95% CI 0.14, 0.92), about once per year (OR = 0.34; 95% CI 0.13, 0.90) and for less than once per year (OR = 0.22; 95% CI 0.07, 0.64) than for those who never visited a dental professional. Recent immigrants, males, individuals aged 70 years or more and those with a low household income were less likely to visit a dental professional than established immigrants, females, younger age groups or those with higher incomes. CONCLUSION: Better policies are needed to address the dental health concerns of recent immigrants who may suffer from poorer dental health, to ensure that they receive the care they require.

Soil-targeted interventions could alleviate locust and grasshopper pest pressure in West Africa.

Agricultural land use has intended and unintended consequences for human livelihoods through feedbacks within coupled human and natural systems. In Senegal, West Africa, soils are a vital resource for livelihoods and food security in smallholder farming communities. In this study, we explored the connections among land use, soil conditions, plant nutrient content, and the abundance of several locust and grasshopper species. We worked in two rural farming villages in the Kaffrine region of Senegal. Oedaleus senegalensis was least abundant in groundnut areas where plant N was highest and abundance was negatively correlated with plant N across land use types. Overall, grasshoppers were most numerous in grazing and fallow areas. There was little variation in soil properties across land use types and soil organic matter (SOM) and inorganic soil N content were low throughout. SOM was positively correlated with soil inorganic N concentration, which in turn was positively correlated with plant N content. Of the management practices we surveyed, fallowing fields was important for soil N and SOM replenishment. These results corroborate other research indicating that land use, management practices, soil and plant nutrients, and insect herbivore abundance are mechanistically coupled. Although further research is needed, improving soil fertility could be used as an alternative to pesticides to keep locusts at bay and improve crop yields.
