Anthropometric Measurements: Options for Identifying Low Birth Weight Newborns in Kumasi,Ghana

Background

In Ghana, 32% of deliveries take place outside a health facility, and birth weight is not measured. Low birth weight (LBW) newborns who are at increased risk of death and disability, are not identified; 13%–14% of newborns in Ghana are LBW. We aimed at determining whether alternative anthropometrics could be used to identify LBW newborns when weighing scales are not available to measure birth weight.

Methods

We studied 973 mother and newborn pairs at the Komfo Anokye Teaching and the Suntreso Government hospitals between November 2011 and October 2012. We used standard techniques to record anthropometric measurements of newborns within 24 hours of birth; low birth weight was defined as birth weight <2.5kg. Pearson''s correlation coefficient and the area under the curve were used to determine the best predictors of low birth weight. The sensitivity, specificity and predictive values were reported with 95% confidence intervals at generated cut-off values.

Results

One-fifth (21.7%) of newborns weighed less than 2.5 kg. Among LBW newborns, the following measurements had the highest correlations with birth weight: chest circumference (r = 0.69), mid-upper arm circumference (r = 0.68) and calf circumference (r = 0.66); the areas under the curves of these three measurements demonstrated the highest accuracy in determining LBW newborns. Chest, mid-upper arm and calf circumferences at cut-off values of ≤29.8 cm, ≤9.4 cm and ≤9.5 cm respectively, had the best combination of maximum sensitivity, specificity and predictive values for identifying newborns with LBW.

Conclusions

Anthropometric measurements, such as the chest circumference, mid-upper arm circumference and calf circumference, offer an opportunity for the identification of and subsequent support for LBW newborns in settings in Ghana, where birth weights are not measured by standardized weighing scales.     

The microbiological quality of drinking water sold on the streets in Kumasi,Ghana

AIM: The aim of this study was to assess the microbiological quality of Ghanaian bottled and plastic-bagged drinking water sold on the streets of Metropolitan Kumasi, Ghana. METHODS AND RESULTS: Eight bottled, 88 factory-filled plastic sachet and 40 hand-filled hand-tied polythene-bagged drinking waters were examined for the presence of heterotrophic bacteria total viable counts (TVCs), indicators of faecal contamination (total coliforms, faecal coliforms and enterococci) and for lead, manganese and iron. Heterotrophic bacteria were found in all three types of water with TVCs per millilitre ranging from 1 to 460 for bottled water, 2-6.33 x 10(5) for factory-bagged sachet water and 2.33 x 10(3)-7.33 x 10(12) for hand-filled hand-tied bagged water. None of the microbial indicators of faecal contamination were detected in bottled water, whereas 4.5% of the factory-bagged sachets contained total coliforms and 2.3% faecal coliforms, and 42.5% of the hand-filled hand-tied bags contained total coliforms, 22.5% faecal coliforms and 5% enterococci. Iron was found in all three types of drinking water but at concentrations well within the WHO recommendations. Lead and manganese were not detected. CONCLUSION: Ghanaian bottled water is of good microbiological quality but some factory-bagged sachet and hand-filled hand-tied polythene-bagged drinking water are of doubtful quality. SIGNIFICANCE AND IMPACT OF THE STUDY: Factory-bagged sachets and hand-filled hand-tied bags of drinking water sold in Ghana should be monitored for microbiological contamination, with the aim of raising standards in the industry and re-assuring the public.     

Spatial patterns and determinants of wetland vegetation distribution in the Kumasi Metropolis,Ghana

The contribution of wetlands to livelihood in the forms of resources of direct consumptive uses, fishing and agriculture are of great importance to riparian communities in sub-Saharan Africa. It is unfortunate to note that these same areas are being degraded and converted to informal settlements through uncontrolled urbanisation. To improve urban environments and meet the various development targets, efforts are being made to rid sub-Saharan African cities of these informal wetland associated slums. The difficulty, however, lies in delineating wetland boundaries. This research is therefore aimed at determining the vegetation diversity of wetlands in Kumasi, Ghana and to identify and characterise the typical urban wetland and factors that influence the small scale heterogeneity in distribution of the wetland vegetation. Ten relatively large wetland sites associated with streams within the Kumasi Metropolis were selected for this study. Sampling in each site was done using 1 m² quadrats laid at 10 m intervals from the water channel. All plant species in each quadrat were identified. The soil and hydrologic conditions of each site were studied. A total of 112 species were identified in the 10 study sites. The study sites were found to be significantly different from each other in environmental conditions and species distribution. Species in these study sites could, however, be grouped into clusters according to the presence or absence of surface water. A wetland in Kumasi was found to be typified by high percentage organic carbon with Thelypteris palustris as the dominant species.     

X-ray Fluorescence (XRF) Analysis of Soil Heavy Metal Pollution from an Industrial Area in Kumasi,Ghana

Knowledge of soil heavy metal concentration is very important for assessing the purity and quality of the soil in an environment. The concentrations of nine heavy metals (NHM), Zn, Pb, Cr, Cu, Co, Ni, Cd, Hg, and As, from the near-surface soils (～ 0–15 cm) from an industrial cluster in Kumasi, Ghana, were qualitatively and quantitatively measured and analyzed using X-ray fluorescence (XRF) spectroscopy analysis. The sources of these NHM were mainly anthropogenic as a result of the indiscriminate industrial waste disposal. In all, a total of about 100 soil samples were taken from six sampling sites, four of which were industrial and the remaining two residential. Forty soil samples out of the total number were carefully selected for elemental analyses and the mean heavy metal concentrations were calculated using statistical methods. The results from locations of high industrial impact showed that the mean concentrations of the NHM present in the soil were in the order of Zn (189.2?908.6 mgkg^?1), Pb (133.7?571.3 mgkg^?1), Cr (91.3?545.8 mgkg^?1), Cu (62.9?334.6 mgkg^?1), Co (38.6?81.9 mgkg^?1), Ni (12.4?30.9 mgkg^?1), Cd (6.9?13.2 mgkg^?1), Hg (5.5?10.4 mg kg^?1), and As (2.3?18.6 mgkg^?1). Apart from Ni and As, all the heavy metals recorded concentrations that ranged from 10?900% higher than their respective threshold limit values (TLVs). Heavy metal concentrations from the residential sites were comparatively far lower with only Cr, Cd, and Hg registering concentrations between 65?250% above their TLVs. The cluster with its residential communities is at a serious risk of soil heavy metal toxicity and awareness to this needs to be created as such.     

The kin of the gene: the medicalization of family and kinship in American Society

In the past several decades there has been an explosion of research in genetics and on genetic inheritance. This new genetics is part of contemporary biomedicine and forecasts great advances in alleviating disease and prolonging human life. It also encompasses notions about biological family and kinship relations. I propose that with the advent of the new genetics, family and kinship are being medicalized. I explore the ways in which explanations of the inheritance of genetic disease influence people's understandings of family and kin and both reflect and conflict with broader current sociocultural processes. The discussion includes a brief overview of the anthropological study of kinship, the meaning of family and kinship in contemporary society, the concept of medicalization and its implications for people's lives as seen through narratives and concludes with an analysis the significance of the medicalization of family and kinship in present-day society.     

Kinship,a-kinship,anti-kinship: Variation in the logic of kinship situations

Where contrasts between rural/urban, non-industrial/industrial, simple/complex et cetera societies are drawn, a corresponding contrast in the importance of kinship as an organising principle is more or less explicitly implied. Similarly, the weight put upon kinship is assumed to vary inversely with technological and/or social evolution. The analytical and practical effects of these assumptions are examined with reference to situations involving kinsmen in Lesotho (Southern Africa), in other non-industrial societies, and in middle-class Great Britain.The paper aims (a) to account for the unexpected non-use of kinship as a consistent organising principle in Lesotho, and (b) to demonstrate that kin-ties are nowhere consistently used since they are social resources whose existence will be exploited, ignored or denied as the logic of particular situations demands; that relations between kinsmen in any society may be governed by any one of three different kinship principles—kinship, a-kinship or anti-kinship.By corollary it is argued that the real significance of kinship can neither be read off an evolutionary continuum, nor denied on the grounds of inconsistent usage.     

Assessment of local wood species used for the manufacture of cookware and the perception of chemical benefits and chemical hazards associated with their use in Kumasi,Ghana

Background

Historical proven wood species have no reported adverse health effect associated with its past use. Different historical proven species have traditionally been used to manufacture different wooden food contact items. This study uses survey questionnaires to assess suppliers’, manufacturers’, retailers’ and consumers’ (end-users’) preferences for specific wood species, to examine the considerations that inform these preferences and to investigate the extent of awareness of the chemical benefits and chemical hazards associated with wooden food contact material use.

Methods

Through the combined use of a cross sectional approach and a case study design, 25 suppliers, 25 manufacturers, 25 retailers and 125 consumers (end-users) of wooden food contact materials in four suburbs in Kumasi Metropolitan Area (Anloga junction, Ahinsan Bus Stop, Ahwia-Pankrono and Race Course) and Ashanti Akyim Agogo in the Ashanti Akyim North District of the Ashanti Region were administered with closed ended questionnaires. The questionnaires were prepared in English, but local language, Twi, was used to translate and communicate the content of the questionnaire where necessary.

Results

Suppliers’, manufacturers’ and retailers’ preferences for specific wood species for most wooden cookware differed from that of consumers (end-users). But all respondent groups failed to indicate any awareness of chemical benefits or chemical hazards associated with either the choice of specific wood species for specific wooden cookware or with the general use of wooden food contact materials. The lack of appreciation of chemical benefits or hazards associated with active principles of wooden cookware led to heavy reliance of consumers (end-users) on the wood density, price, attractive grain pattern and colour or on the judgement of retailers in their choice of specific species for a wooden cookware.

Conclusion

This study contributes some practical suggestions to guide national policy development on improvement in quality of available wooden food contact materials in Ghana.

     

The Chinese family as instituted fantasy: or,rescuing kinship imaginaries from the ‘symbolic’

This article revisits well‐travelled ethnographic portrayals of traditional Chinese family dynamics to draw attention to desire as a product of family life and to how crucial elements of family organization and ideology can be understood, in turn, as effects of desire – that is, as instituted fantasies. Although my case in point is the Chinese family, the analysis addresses the category ‘family’ cross‐culturally. In any of its variations, the ‘family’ exists at two synergistically implicated levels: first, it comprises an important part of the reality into which individuals are socialized; second, it embodies in instituted form individuals' attempts to realize – to bring into being – social arrangements as they would like them to be. In the Chinese case, at least two ironies are embedded in this synergy. First, women are primary producers and reproducers of the family in the ‘real world’, despite the fact that patriliny as ‘instituted fantasy’ downplays or veils their agency. Second, the normative subordination of the son to a patriarchal father, expressed and mediated through institutions including ancestor worship and valorization of filial piety, veils a valorizing of the son as agent or protagonist of filial action. Although ultimately unrealizable, patrilineal and familial fantasies animate Chinese family life and are thus an important constituent of Chinese realities. To these ends the analysis re‐purposes ‘the symbolic’ and ‘imaginaries’, categories widely employed in contemporary gender studies and social theory, arguing that understanding kinship enjoins incorporating desire's role both in defining institutions and in motivating their creators.     

Raising the roof in the transnational Andes: building houses, forging kinship

Transnational migration transforms houses, the rituals surrounding them, and the people who live in those houses and use them to understand aspects of their social and ethnic identities. I focus on the Andean house-roofing ritual known as the zafacasa to demonstrate the centrality of the house as a mediator for personal relationships, and the importance of such rituals for reconstituting social bonds both in spite of and because of distance. The article goes on to argue that research on consumption should be complemented by a kinship framework in order fully to represent the local meanings of expenditures.  

Résumé

La migration transnationale transforme les maisons, les rituels qui les entourent et les gens qui les habitent et les utilisent pour saisir certains aspects de leur identité sociale et ethnique. L'auteur s'intéresse au rituel de pose de toit andin connu sous le nom de zafacasa pour démontrer le rôle central de la maison en tant que médiateur de relations personnelles et l'importance de ces rituels pour la reconstitution de liens sociaux malgré, et à cause de, la distance. L'article avance qu'il serait utile d'ajouter aux recherches sur la consommation un cadre concernant la parenté, afin d'appréhender de façon plus complète la signification locale des dépenses.     

Relative indemnity: risk,insurance, and kinship in Indian microfinance

With the growth of commercial microfinance in India, the poor have been increasingly enfolded into circuits of global finance. In making these collateral‐free loans, however, microfinance institutions (MFIs) engage in new forms of risk management. While loans are made to women with the goal of economic and social empowerment, MFIs require male kin to serve as guarantors. Drawing on fieldwork in the city of Kolkata, I argue that through the requirement of male guarantors, MFIs hedge on kinship, even as they speculate on the bottom of the pyramid as a new market of accumulation.     

Analytical DNA fingerprinting in lions: parentage, genetic diversity, and kinship

The application of hypervariable minisatellite genomic families to the reconstruction of population genetic structure holds great promise in describing the demographic history and future prospects of free-ranging populations. This potential has not yet been realized due to unforeseen empirical constraints associated with the use of heterologous species probes, to theoretical limitations on the power of the procedure to track genic heterozygosity and kinship, and to the absence of extensive field studies to test genetic predictions. We combine here the technical development of feline-specific VNTR (variable number tandem repeat) families of genetic loci with the long-term demographic and behavioral observations of lion populations of the Serengeti ecosystem in East Africa. Minisatellite variation was used to quantify the extent of genetic variation in several populations that differed in their natural history and levels of inbreeding. Definitive parentage, both maternal and paternal, was assessed for 78 cubs born in 11 lion prides, permitting the assessment of precise genealogical relationships among some 200 lions. The extent of DNA restriction fragment sharing between lions was empirically calibrated with the coefficient of relatedness, r, in two different populations that had distinct demographic histories. The results suggest that reliable estimates of relative genetic diversity, of parentage, and of individual relatedness can be achieved in free-ranging populations, provided the minisatellite family is calibrated in established pedigrees for the species.     

Cogealing divinity: time, worship and kinship in South Indian Hinduism

Daily worship in Hindu temples is characterized by regular repetition. This article juxtaposes iconography and mythology; field data on worship in a Murukan temple in Kalugumalai, South India; and analytic concepts from western and Indian metaphysics, to examine what Gell termed the 'ritual manipulation of time'. In Hindu cosmology, the materialization of divinity – a prerequisite for worship – is inseparably linked not only to the emergence of time but also to the devolution of divinity into gendered forms. Because gender differences play a central role in iconography, mythology and worship, Hinduism provides a rich cultural resource for debating the morality and practice of human kinship, sexuality and procreation. Not only are there significant homologies between human and divine kinship behaviour, but human marriage patterns in South India display the same blend of repetitive yet changing oscillation as do daily and annual temple liturgies.     

Blood is not always thicker than water:The limited effect of kin selection on human kinship in the traditional Chinese family

To examine the importance of kin selection in shaping human societies, this study analyzed the kinship system practiced in traditional China for two millennia and teased apart its underlying genetic and other, presumably cultural, components.The results demonstrate that, in the traditional patrilineal Chinese family, both genetic relatedness and the cultural factor of generation were important in determining kinship status for male agnates (genetically related relatives). For female agnates, however, only genetic relatedness was important. Another surprising finding was that the influence of gender was not as important as genetic relatedness. The most interesting finding in this study, however, was that kin selection and culture (I.e., seniority in generation and age) played vastly different roles in different lineages in the Chinese family: for collateral (indirect) agnates, genetic relatedness was the most important factor in determining their kinship status, but for lineal (direct) agnates, its importance was overridden by seniority in generation and age, a cultural factor. Several other bio-cultural factors also explained a considerable amount of variance in kinship status. Since kinship profoundly affected, and was often the foundation of, the legal and social systems in dynastic China, kin selection, while its strength may differ remarkably between lineal and collateral relatives, could act as a selective force in Chinese families.     

Occult return,divine grace,and saabui: practising transnational kinship in postsocialist Guinea

In the Republic of Guinea, where transnational migration has become a critical path to prestige among young urbanites, migrant success abroad is intimately connected to the cultivation of kin ties at home. For performing artists, who were the darlings of Guinea's Socialist Revolution (1958‐84), the experience of migration is uniquely linked to the fall of the socialist state and to the precarity of urban life in contemporary Africa. This article describes how Guinean artists manage distance and uncertainty through three practices: occult aggression, grace‐seeking, and patronage (saabui), which together illustrate the contours and limitations of kinship's efficacy in transnational space. By exploring transnational kinship as an intersubjective and productive practice that can extend beyond obligation or solidarity and into the realm of magic, this article proposes new ways of conceptualizing what it means for migrants to maintain significant connections across national borders.
