Assessment and predictors of blood glucose levels in hypertensives attending a secondary health centre: relationship with physical activity and diet quality
Get PDFThe aim: this study aims to assess the prevalence of hyperglycaemia, the association between diet quality, physical exercise and blood glucose levels among hypertensives attending a secondary health centre in Nigeria. There is a paucity of data concerning these issues and the study would contribute positively to future management of the patients.
Methods: the study was a cross-sectional study of 354 hypertensives that was conducted at the State Hospital, Oyo, Nigeria. The systematic sampling technique was used to recruit patients, and the data were analysed using SPSS software version 23. Linear regression was done to determine the predictors of hyperglycaemia, and logistic regression was done to determine the predictors of diet quality.
Results: the mean age of the respondents was 52.60(SD±8.26) years. The prevalence of undiagnosed diabetes in this cohort was 19.60 %. The association of glycated haemoglobin (HbAic) with High Density Lipoprotein (HDL) was negative, weak in strength and statistically significant (p-value=0.034). For every 1 unit decrease in High Density Lipoprotein (HDL), there was a statistically significant increase in HbAic by about 0.383 units (95 % C.I equals -0.737 to -0.029, p-value=0.034). For every 1 unit increase in total Cholesterol, there was a significant increase in HbAic by about 0.158 units (95 % CI equals 0.007 to 0.308, p-value=0.04). Age group <45 years were about 2 times less likely to have good diet quality than those of 55 years and above (OR=0.502; 95 % CI=0.270 – 0.932, p-value=0.029).
Conclusions: the study has assisted to characterise this population of hypertensives in terms of serum glucose levels. The prevalence of hyperglycaemia was high among these hypertensives. The predictors of hyperglycaemia were HDL and Cholesterol. Also, the predictor of good diet quality was the age of the respondent
Predictors of blood pressure levels, knowledge and practices of adult hypertensives attending a Secondary Health Care Centre in South-Western Nigeria
Get PDFIntroduction and aim. The prevalence of hypertension is increasing with accompanying poor control. The aim of this study was to assess the predictors of knowledge and practices of adult hypertensives.
Material and method. The study was a prospective (before and after) study with health education as the intervention. A simple random sampling technique with computer-generated random numbers was used to recruit 386 patients. Data were analysed using SPSS version 23. Logistic regressions were used to determine the predictors of knowledge and practices.
Results. Those who had tertiary education were about four times more likely to have good knowledge of hypertension than those who had secondary education (OR=0.256; 95% CI=0.106–0.617). The females were about 1.73 times more likely to have good practices of hypertension than males (OR=1.729; 95% CI=1.008–2.966). For every 1 unit increase in the body mass index, there was a statistically significant increase in diastolic blood pressure by about 0.22 units (95% CI=0.046–0.394, p=0.013). The health education had a positive impact on the blood pressure reduction.
Conclusion. The predictors of knowledge of hypertension, practices of hypertensives and diastolic blood pressure were level of education, sex, and body mass index respectively
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
