Barriers to influenza vaccine uptake in obese people in Italy: Changes 2005–2013

The role of health determinants in the influenza vaccination uptake among older adults (65+): a scope review

“…Table 1 shows determinants clustered by their likelihood to increase or decrease VU for each article analysed, respectively. We found sizeable evidence highlighting a role for several factors at individual level, such as increasing age [11,12,20,28,34,36,39] and decreasing individual health status. The latter included declining functional status or having a chronic diseases, comorbidities or disabilities [9-12, 14, 19, 20, 22, 25, 27-29, 33, 34, 37-39, 42], that supported VU among older people.…”

“…Methods used to evaluate vaccination uptake in the cross-sectional and cohort studies and in the systematic reviews were: questionnaires and surveys [13-15, 19, 21, 22, 25, 28, 34-36]; telephone interviews [20,23,27,29,30,33,39,41]; data retrieved from national/regional authorities and health care institutions [12,38,40,49,50]; data retrieved from medical records or vaccination registries [9,10,31,37]; combined methods [11,17,18,24]; focus group discussions [26,32]; face-to-face interviews [42]; database search [47,48].…”

“…The number of participants older than 65 years of study samples ranges from 11% to 100% of all initially included study participants (n= 19.604.711) from across the globe in countries from four continents and in following care settings: Community-dwelling or non-institutionalized citizens [9, 15, 21, 23, 27-31, 33, 36, 39, 42, 48, 50], nursing homes [12,38], combined settings [32,37], outpatient clinics [44], hospitals [18,22], primary care centres/clinics or practices [24,26,43,45], home-based primary care settings [10] and data bases such as the Medicare registry, national vaccine industry or settings of health services/insurance authorities [13,40,46]. In 12 studies, details about the care setting of the participants were not indicated [11,14,16,17,19,20,25,34,35,41,47,49].…”

“…Not surprisingly, older citizens with positive attitudes towards VU also reported on having other vaccinations such as pneumococcal vaccination [18]. Furthermore, life-style factors as smoking, low physical activity levels, inadequate diet and alcohol consumption seem to be negatively associated with VU [11,14,19,28,39]. Some studies point to the direction that a higher educational level or higher socio-economic status may support VU in the elderly [20,29,[39][40][41]50].…”

“…Only a few publications were found reporting results of interventions on system level, one study found out that countries with good monitoring systems regarding VU rates exhibit higher vaccination coverage on average [13]. Additional policy elements also have the potential to increase VU rates [11,13]. Figure 2 summarizes the single elements in uencing seasonal in uenza vaccination uptake among older citizens detected during our search in an ecosystem.…”
