Effectiveness of nutritional interventions addressed to elderly persons: umbrella systematic review with meta-analysis.

Background: The number of Europeans aged over 65 will double between 2010 and 2060, reaching 30% of the European population. Nutrition is emerging as a key element of healthy life since both obesity and malnutrition are established risk factors for morbidity and disability. The aim of this umbrella review (UR) is to summarize the findings of all current systematic reviews (SRs) and meta-analyzes (MAs) on the effectiveness of nutritional intervention designed to promote healthy aging in older individuals. Methods: Eligible articles published in English or Italian between January 2000 and May 2016 were identified in six databases. Only studies that analyzed nutritional interventions in the population of 65 years and over, or papers specifically targeting older adults were deemed eligible. Results: Twenty-eight papers, out of which twenty-five SRs and three MAs, met the inclusion criteria and were included in this umbrella SR. Supplementation with vitamin D and other kind of products was highly effective in preventing falls and fractures. Furthermore, several interventions, ranging from the prescription of supplements to environmental and organizational programs, resulted in an improvement in energy and protein intake, as well as positive weight outcomes. Positive findings were also found for the elderly at risk of malnutrition and for older patients with dementia. Conclusions: The findings of this UR indicate that the use of a wide range of supplements and environmental and organizational intervention improve a number of anthropometric, nutritional and functional indices in the elderly.

Scoping review of health promotion and disease prevention interventions addressed to elderly people.

BACKGROUND: The ageing of modern societies remains one of the greatest challenges for health and social systems. To respond to this challenge, we need effective strategies assuring healthy active life for elderly people. Health promotion and related activities are perceived as a key intervention, which can improve wellbeing in later life. The main aim of this study is the identification and classification of such interventions addressed to older adults and elderly. Therefore, the strategy based on the scoping review as a feasible tool for exploring this domain, summarizing research findings and identifying gaps of evidence, was applied. METHODS: The scoping review relies on the analysis of previous reviews of interventions aimed at older adults (55-64 years old) and elderly persons (65 years and above) assessed for their effectiveness in the framework of a systematic review and/or meta-analysis. The search strategy was based on the identification of interventions reported as health promotion, primary disease prevention, screening or social support. In the analysis, the reviews published from January 2000 to April 2015 were included. RESULTS: The search strategy yielded 334 systematic reviews and/or meta-analyses addressed to target groups of interest, 182 of them assessed interventions belonging to health promotion, 219 to primary prevention, 34 to screening and 35 to social support. The studies focused on elderly (65 years and above) made up 40.4 % of all retrieved reviews and those addressing population of 55 years and above accounted for 24.0 %. CONCLUSIONS: Interventions focused on health maintenance and improvement in elderly and older adults represent frequently combined health promotion and disease prevention actions. Many interventions of this type are not addressed exclusively to elderly populations and/or older adults but are designed for the general population. The most common types of interventions addressed to elderly and older adults in the area of health promotion include health education, behavior modification and health communication.

The Use of E-Cigarettes among High School Students in Poland Is Associated with Health Locus of Control but Not with Health Literacy: A Cross-Sectional Study.

Since their introduction, the use of electronic cigarettes has increased considerably in the population and among adolescents. Determinants of smoking conventional cigarettes were thoroughly studied in various social groups. However, we know less about the predictors of the use of e-cigarettes in younger generations. The main aim of this study was the assessment of the factors associated with the use of electronic cigarettes among high school students. Specifically, the roles of health literacy (HL) and health locus of control (HLC) were addressed. The analysis was based on the data from a 'pen-and-pencil' survey performed in a large sample of 2223 high school students from southern Poland. The tools used in the survey encompassed 133 items, including a 47-item European Health Literacy Survey questionnaire, an 18-item Multidimensional Health Locus of Control Scale, and a set of questions asking about the health behaviors, and sociodemographic and economic characteristics of respondents. In the study sample, 47.5% of the respondents had used e-cigarettes in the past, and 18.6% had used them in the last month. HL was not significantly associated with dependent variables reflecting the use of e-cigarettes. Two types of external HLC were associated with using e-cigarettes in the past, and 'Chance' HLC (CHLC) was also associated with their use in the last month. Males, students of schools providing vocational training, and students declaring more Internet use during the week showed a higher likelihood of ever using e-cigarettes or using them in the last month. Students smoking conventional cigarettes were also more prone to use e-cigarettes. To sum up, it was an unexpected result that HL is not associated with the use of e-cigarettes. A greater likelihood of using e-cigarettes was positively associated with higher CHLC scores, as in the case of smoking traditional cigarettes.

The Association between Future Anxiety, Health Literacy and the Perception of the COVID-19 Pandemic: A Cross-Sectional Study.

Increased anxiety related to the Coronavirus Disease 2019 (COVID-19) pandemic in society and specific professional groups has been reported by many authors. Most have applied tools enabling assessing the general traits of anxiety. Tools specifically designed for an assessment of anxiety or fear related to COVID-19 have also been developed. However, no study has assessed the future anxiety in relation to the pandemic. This concept was defined by Zaleski in the end of the 20th century as the state of apprehension, fear, worry, and concern regarding unfavourable changes in the more remote personal future. The aim of this study was an analysis to establish the level and the determinants of future anxiety in Polish society related to the COVID-19 pandemic three months after the introduction of the state of epidemic. The analysis reported in the paper is based on the data obtained through a web-based survey carried out on a representative sample of 1002 Polish adults aged 18-74 years. The hierarchical linear regression model was developed for the analysis of the determinants of future anxiety from the responses to a questionnaire consisting of five items. The independent variables selected for inclusion in the model, apart from sociodemographic characteristics, encompassed health literacy (HL) and ehealth literacy (eHL), perceived health threat related to COVID-19 (PHTC19), and a COVID-19-related conspiracy belief score (CCBS) derived from three items asking about the most popular conspiracy theories. The regression model developed in the final step showed that the future anxiety scale score (FASS) was significantly associated with gender, vocational status, HL, PHTC19, and CCBS. The FASS was lower among men than women (regression coefficient (B) (standard error, SE) = -1.28 (0.39), p = 0.001), among entrepreneurs or farmers rather than among employees of the public or private sector (B(SE) = -1.55, p = 0.010), in persons with a higher HL (B(SE) = -0.43 (0.06), p < 0.001). A higher FASS was observed in respondents with higher rather than lower PHTC19 (B(SE) = 1.49 (0.17), p < 0.001) and in those with a higher CCBS (B(SE) = 0.33 (0.07), p < 0.001). The model accounted for 15.2% of the variance of the FASS. In conclusion, the COVID-19 pandemic is not only a cause of increased mental symptoms, but also of increased future anxiety. Health-related measures are significantly associated with the FASS.

Socio-Economic Determinants of Health Literacy in High School Students: A Cross-Sectional Study.

Today, a person's health literacy (HL) is perceived as a critical determinant for their health. It is well known that limited health literacy is associated with harmful health behaviours, the lower use of preventive services, problems in making use of healthcare resources and poor skills for the self-management of chronic disorders. This study analysed the level and factors associated with HL in high school students in southern Poland. The study is based on the data from a paper-and-pencil survey of high schools students in the Malopolska Voivodshop. The students were selected using a two-stage cluster random sampling procedure. The level of HL was assessed with the European Health Literacy Survey Questionnaire, consisting of 47 items. Univariate logistic and linear regression models were applied to analyse the association between general HL score and the main domain-specific indices. The respondents whose parents had attended University and came from more affluent families were less likely to demonstrate limited HL. There was a significant positive relationship between the self-assessment of the economic situation, size of accommodation, the level of expenditure on a mobile phone and receiving external support, the size of the book collection at home, and domain-specific HL sub-indices. In conclusion, among socio-demographic factors, the parents' education is the only consistent predictor of the level of HL in high school students. Furthermore, most variables reflecting the economic status of the respondent's family are significantly associated with the general HL score and its sub-indices.

Nutritional Behaviors, Health Literacy, and Health Locus of Control of Secondary Schoolers in Southern Poland: A Cross-Sectional Study.

Nutritional behaviors remain an essential part of a healthy lifestyle. It seems obvious that unfavorable health behaviors adopted in adolescence are maintained late in adulthood and may have a profound effect on health status. The main aim of this study was to assess the association between nutritional behaviors and health literacy (HL), health locus of control (HLC), and socioeconomic variables in secondary school pupils from a voivodship (the main unit of territorial division) in southern Poland. The analysis was based on dataTable from a paper-and-pencil survey taken by 2223 pupils from schools selected as the result of cluster sampling. The survey questionnaire encompassed a set of five items asking about dietary patterns and the consumption of fruit and vegetables as well as fast food, a European Health Literacy Project Questionnaire consisting of 47 items, the Multidimensional Health Locus of Control (MHLC) scale, and items asking about sociodemographic and economic variables. Uni- and multivariate logistic regression models have been developed to assess the predictors of indicator nutrition behaviors. The adjusted models revealed that internal HLC was not significantly associated with any of analyzed nutritional behaviors. "Powerful other HLC" and "Chance HLC" (dimension of external HLC) were significant predictors of the selected dietary patterns. Furthermore, higher HL was associated with higher consumption of fruit and vegetables [odds ratio, 95% confidence interval (OR, 95% CI)]: 1.02 (1.01-1.04) and with lower consumption of fast food (OR, 95% CI, 0.98, 0.95-0.999). There was a significant relationship between gender, the size of the household, self-assessed economic situation, expenditures on mobile phones, and weekly duration of Internet use and selected nutrition behaviors. In conclusion, developed regression models confirmed a significant relationship between HL and the types of consumed food, but not with dieting patterns. Contrary to earlier studies, internal HLC was not associated with nutrition behaviors. In our study, boys showed more favorable nutritional behaviors than girls. More intense use of the Internet was associated with less beneficial nutritional behaviors. This study brings important results that should have an impact on health promotion interventions addressed to adolescents in southern Poland.

Interventions targeting loneliness and social isolation among the older people: An update systematic review.

This systematic review aims to summarize and update the current knowledge on the effectiveness of the existing interventions for alleviating loneliness and social isolation among older persons. A search of PubMed, ISI Web of science, SCOPUS, The Cochrane Library, and CINAHL databases was performed. The terminology combined all possible alternatives of the following keywords: social isolation, loneliness, old people, intervention and effectiveness. Eligible studies were published between January 2011 and February 2016 in English or Italian language and regarded the implementation of loneliness/social isolation interventions among the older generations. Outcome measures in terms of the intervention effects needed to be reported. In total, 15 quantitative and five qualitative studies were ultimately included in this review. Eighteen interventions were reported across the quantitative studies. Six out of 11 group interventions (55%), one out of four mixed interventions (25%) and all three individual interventions reported at least one significant finding related to loneliness or social isolation. Our review suggested that new technologies and community engaged arts might be seen as a promising tool for tackling social isolation and loneliness among the older individuals. Future studies need to work on methodological quality and take into consideration the suggestions of the present literature in order to provide firm evidence.
