Determinants of health care seeking for childhood illnesses in Nairobi slums
No full textThe practice of appropriate health seeking has a great potential to reduce the occurrence of severe and life-threatening child illnesses. We assessed the influence of socio-demographic, economic and disease-related factors in health care seeking for child illnesses among slum dwellers of Nairobi, Kenya. A survey round of the Nairobi Urban Demographic Surveillance System (NUDSS) generated information on 2-week child morbidity, illness symptoms, perceived illness severity and use of modern health services. During this round of data collection, interviewers visited a total of 15 174 households, where 3015 children younger than 5 years lived. Of the 999 (33.1%) children who were reported to have been sick, medical care of some sort was sought for 604 (60.5%). Lack of finances (49.6%) and a perception that the illness was not serious (28.1%) were the main reasons given for failure to seek health care outside the home. Health care seeking was most common for sick children in the youngest age group (0–11 months). Caretakers sought medical care more frequently for diarrhoea symptoms than for coughing and even more so when the diarrhoea was associated with fever. Perception of illness severity was strongly associated with health care seeking. Household income was significantly associated with health care seeking up to certain threshold levels, above which its effects stabilized. Improving caretaker skills to recognize danger signs in child illnesses may enhance health-seeking behaviour. Integrated Management of Child Illnesses (IMCI) programmes must be accessible free of charge to the urban poor in order to increase health care seeking and bring about improvements in child survival.<br/
Comparing maternal health indicators between teenagers and older women in sub-Saharan Africa: evidence from DHS
No full textDHS data from 21 countries in sub-Saharan Africa are used to examine maternal health indicators among teenagers. A comparison is made between teenagers and older women, based on logistic regression analyses for individual countries and multilevel logistic analyses applied to merged data, controlling for the effect of socio-economic and demographic factors. Teenagers are found more likely to report unintended fertility (especially mistimed), receive inadequate antenatal care (start late and attend fewer visits), have non-facility delivery, and have a small baby at birth. However, teenagers are less likely to have had Caesarean section deliveries compared to older women. There are significant differences in maternal health indicators between countries but the observed pattern by maternal age does not vary significantly between countries, suggesting that these patterns are generalizable for the region. For teenagers with characteristics associated with higher Caesarean section or unwanted fertility rates, being in countries with overall higher risks of these outcomes particularly amplifies their chances of experiencing them
Child morbidity and healthcare utilization in the slums of Nairobi, Kenya
No full textRapid urbanization and inequitable distribution of social services in African cities significantly contribute to the current deterioration of child health indicators in the region. Determinants of child morbidity and healthcare utilization among slum residents in Nairobi City, Kenya were assessed. Using a morbidity surveillance system, we visited 1691 households every 90?days for 9?months and registered 696 children below 5?years. 264 (37.9 per cent) children were reported to have been sick or injured at least once during the study period. A total of 447 illness episodes were reported among the 264 children (an average of 1.7 episodes per child). Cough, fever, diarrhea, skin problems and eye diseases made up the top five causes of morbidity. Child age below 1 year (OR = 2.7; 95 per cent CI = 1.33, 5.49) and having a working-mother (OR = 2.0; 95 per cent CI = 1.19, 3.31) were significantly associated with child morbidity report. About half of the mothers sought proper medical care for their sick children mostly from health institutions located outside the slum. Healthcare seeking within the slum heavily relied on informal private clinics. Working mothers sought medical care more often than non-working mothers (OR = 0.29; 95 per cent CI = 0.12, 0.7) and infants got priorities compared to older sick children (OR = 0.2; 95 per cent CI = 0.05, 0.83). We conclude that maternal engagement in non-formal low-paying jobs might in the long-run have a questionable gain in child survival among slum resident

Full text linkBackgroundThe linkage between the socio-economic inequality and HIV outcomes was analysed using data from a population-based household survey that employed multistage-stratified sampling. The goal is to help refocus attention on how HIV is linked to inequalities.MethodsA socio-economic index (SEI) score, derived using Multiple Correspondence Analysis of measures of ownership of durable assets, was used to generate three SEI groups: Low (poorest), Middle, and Upper (no so poor). Distribution of HIV outcomes (i.e. HIV prevalence, access to HIV/AIDS information, level of stigma towards HIV/AIDS, perceived HIV risk and sexual behaviour) across the SEI groups, and other background characteristics was assessed using weighted data. Univariate and multivariate logistic regression was used to assess the covariates of the HIV outcomes across the socio-economic groups. The study sample include 14,384 adults 15 years and older.ResultsMore women (57.5%) than men (42.3%) were found in the poor SEI [P<0.001]. HIV prevalence was highest among the poor (20.8%) followed by those in the middle (15.9%) and those in the upper SEI (4.6%) [P<0.001]. It was also highest among women compared to men (19.7% versus 11.4% respectively) and among black Africans (20.2%) compared to other races [P<0.001]. Individuals in the upper SEI reported higher frequency of HIV testing (59.3%) compared to the low SEI (47.7%) [P< 0.001]. Only 20.5% of those in poor SEI had \u201cgood access to HIV/AIDS information\u201d compared to 79.5% in the upper SEI (P<0.001). A higher percentage of the poor had a stigmatizing attitude towards HIV/AIDS (45.6%) compared to those in the upper SEI (34.8%) [P< 0.001]. There was a high personal HIV risk perception among the poor (40.0%) and it declined significantly to 10.9% in the upper SEI.ConclusionsOur findings underline the disproportionate burden of HIV disease and HIV fear among the poor and vulnerable in South Africa. The poor are further disadvantaged by lack of access to HIV information and HIV/AIDS services such as testing for HIV infection. There is a compelling urgency for the national HIV/AIDS response to maximizing program focus for the poor particularly women.20131 U2G PS 000570/PS/NCHHSTP CDC HHS/United StatesPEPFAR/United States24180366PMC42284121056
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
