Home alone : sibling caretakers in León, Nicaragua
- 2008
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Sibling caretaking, although common across time and cultures, has not been well researched from the carer’s point of view. In Nicaragua, ranked as one of the poorest countries in the Americas, sibling caretaking is common. The country’s historical background and its state of chronic poverty, widespread unemployment, loose family structures, and migration and mobility makes of the old practise of shared management child care a necessity. Households headed by sing¬le mothers constitute a particular Nica¬raguan charact¬eristic. Many children are expected to help in their own families and care for their siblings and other children living in their households. In its broadest sense sibling caretaking is a public health concern, and we conducted this study to widen the understanding of the phenomenon as it is represented in a setting undergoing a rapid social transition. The main objectives were to identify, describe and analyse the life situation of sibling caretakers in poor areas in León, Nicaragua, with focus on how they perceived it themselves. A combined qualitative and quantitative methodological design was used, mainly applying an ethnographic approach. A further ambition was to explore involvement of children in a participatory research process in accordance with the ‘Convention on the Rights of the Child’. The overall emotion expressed among the caretakers was pride, even if their situation often was characterized by stress and coping problems. They perceived their work as important for their families and they appreciated to fend for their siblings. Household work and nurturing of siblings were shaping the future lives of the caretakers and constituted part of their socialization. Even if many of these children achieve essential life skills as caretakers, they are at risk of falling behind as they grow older. Their long-term personal development is likely to be hampered by the obligations they have as caretakers. The carers' awareness of missing out on education was the most problematic issue for them. From a societal point of view, caretaking has negative consequences. The individual child is marginalised with limited access to basic education, contributing to overall low educational levels in Nicaragua. While the structuring conditions leading to sibling caretaking may be difficult to change, awareness of how these can affect children might make way for improvements in terms of access to school education and support from the society. The knowledge gained from this study should be further utilised to plan for interventions that take children’s perspectives into consideration.

The Impact of Violence Against Women on Child Growth, Morbidity and Survival : Studies in Bangladesh and Nicaragua
- 2008
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The aim of this thesis was to explore the impact of physical, sexual and emotional violence against women of reproductive age and the level of controlling behaviour in marriage on child health and survival in two different cultural settings: Bangladesh and Nicaragua. Data were acquired from four quantitative community-based studies. In two studies, a cohort including a prospective two year follow-up of 3164 mother-infant pairs in rural Bangladesh was investigated. A third study was a case-referent study in Nicaragua including mothers of 110 cases of under-five deaths and 203 referents, and in a forth study an other cohort of 1048 rural Bangladeshi women and their 2691 children was followed until 5 years of age. Maternal exposure to any form of violence, including physical, sexual, emotional, and controlling behaviour was independently associated with lower body size at birth, increased risk of stunting and under-weight at 24 months of age, slower growth velocity during the first two years of life and a higher incidence of diarrhoeal episodes and respiratory tract infections. In the Nicaraguan setting, the children of women who experienced any history of physical violence had a two-fold increase in risk of death before the age of 5 years, and those whose mothers experienced both physical and sexual violence had a six-fold increase in risk of death. In Bangladesh, an association between violence against women and under-five mortality was found among daughters of educated mothers who were exposed to severe physical violence or a high level of controlling behaviour in marriage. In all four studies, lifetime violence experience among participating mothers was high (37-69%), and the timing was less relevant than the exposure to violence per se. In conclusion, this investigation revealed that violence against women severely affects child health and survival. The findings are especially relevant in a context of high level of child under-nutrition, morbidity and under-five mortality. Efforts for protecting women from all forms of violence are needed as part of the interventions for improved child health.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This paper inquires into the various forms of healing performed today among the Miskitu people of the Caribbean coast of Nicaragua. The Miskitu have a long history of relations with outsiders and with people of African origin. Miskitu cosmology and its ideas about illness and healing is today a mixture of indigenous, Afro-Caribbean, and Christian beliefs. Local healers constantly pick up new healing methods and ideas from other religious traditions in Central America, Mexico, and the Caribbean. The paper discusses how Miskitu healers, known as curanderos, sukias, and profetas, heal by relating sickness and suffering to a world of spirits which also makes reference to the plural cultural antecedences of contemporary Miskitu worldview.

- Giardiasis is a major problem in León, Nicaragua, yet despite this no data are available regarding the prevalence of different Giardia genotypes in this area. To address this question, a molecular analysis of Giardia isolates from humans and dogs living in the same area in León, Nicaragua was performed. Giardia isolates from 119 Nicaraguan patients and 8 dogs were successfully genotyped using single and/or nested beta-giardin PCR with subsequent restriction length fragment polymorphism (RFLP) analysis. The analyses of human samples yielded 94 (79%) assemblage B isolates and 25 (21%) assemblage A isolates. Only the non-human-associated assemblages C and D were found in the dog samples. Sixteen isolates with assemblage A pattern, 26 isolates with assemblage B pattern and all dog isolates were further characterized by sequencing the nested beta-giardin PCR product and by molecular analyses of the glutamate dehydrogenase (gdh) gene. Within the study area the assemblage A isolates were highly genetically homogenous, showing only sub-genotypes A2 (n=3) or A3 (n=13) at the beta-giardin locus and AII only at the gdh locus while assemblage B showed a high genetic polymorphism at both loci. Seven different sub-genotypes were identified within 13 of the sequenced assemblage B beta-giardin isolates. The remaining 13 sequenced assemblage B-isolates appeared to contain several different variants of the beta-giardin gene since the chromatograms displayed one to seven double peaks. The gdh sequences showed an even higher polymorphism since only 2 of 26 assemblage B isolates were without double peaks. Two mixed infections between assemblage A and B were found when the gdh gene was analyzed. Polymorphisms were also observed in the dog-associated assemblages C and D, but to a lesser extent than in assemblage B.

- Electrical geophysical surveys in the mode of vertical electrical soundings (VES) and continuous vertical electrical soundings (CVES) were conducted in the Leon-Chinandega plains, northwestern Nicaragua, in order to obtain detailed information about the geometry of the different hydrogeological layers in the aquifer and depth to the basement. A total of 51 VES were carried out within the plains. The results show a complex structure towards the north east of the area, and the southwestern part of the plains presents a smoother stratification. The geoelectrical measurements and borehole information indicate that the basement topography is characterized by hills and deep valleys with highly variable basement depths. Fifty CVES where done in a smaller area in the center of the plain. The resistivity data yielded considerable information revealing the existence of two main geo-electrical units. The combined interpretation of geological and geophysical data shows an environment typical of sedimentary volcanic coastal plains. The information collected during this investigation provides valuable data for estimating the fresh-water resources of the Leon-Chinandega aquifer system and for development of a groundwater management plan.

- The interactions between a stream and nearby shallow aquifers were investigated in a mountain basin being polluted by mercury released during mining in central Nicaragua. Hourly data series of water levels and temperatures were analysed using cross-correlation. Resistivity imaging was used to map the subsurface and to complement the hydrological data interpretation. The results show the complex hydrogeological conditions that characterize the region, with weathering and fractured rock as main contributors to groundwater transport. The resistivity images suggest the presence of two vertical dykes perpendicular to the stream, and zones rich in clay. The data series indicate a rapid response from the aquifers to recharge events, followed by immediate discharge on a yearly basis. Furthermore, alternating periods of stream infiltration and aquifer discharge were identified. This work demonstrates that surface water pollution is a threat to groundwater quality in the area.

- OBJECTIVE: Our aim was to investigate exposure to polybrominated diphenyl ethers (PBDEs) in a young urban population in a developing country, with focus on potentially highly exposed children working informally as scrap scavengers at a large municipal waste disposal site. We also set out to investigate whether hydroxylated metabolites, which not hitherto have been found retained in humans, could be detected. METHODS: We assessed PBDEs in pooled serum samples obtained in 2002 from children 11-15 years of age, working and sometimes also living at the municipal waste disposal site in Managua, and in nonworking urban children. The influence of fish consumption was evaluated in the children and in groups of women 15-44 years of age who differed markedly in their fish consumption. Hydroxylated PBDEs were assessed as their methoxylated derivates. The chemical analyses were performed by gas chromatography/mass spectrometry, using authentic reference substances. RESULTS: The children living and working at the waste disposal site showed very high levels of medium brominated diphenyl ethers. The levels observed in the referent children were comparable to contemporary observations in the United States. The exposure pattern was consistent with dust being the dominating source. The children with the highest PBDE levels also had the highest levels of hydroxylated metabolites. CONCLUSIONS: Unexpectedly, very high levels of PBDEs were found in children from an urban area in a developing country. Also, for the first time, hydroxylated PBDE metabolites were found to bioaccumulate in human serum.

- Information about norovirus (NoV) infections in Central America is limited. Through a passive community and hospital pediatric diarrhea surveillance program, a total of 542 stool samples were collected between March 2005 and February 2006 in León, Nicaragua. NoV was detected in 12% (65/542) of the children; of these, 11% (45/409) were in the community and 15% (20/133) were in the hospital, with most strains (88%) belonging to genogroup II. NoV infections were age and gender associated, with children of <2 years of age (P < 0.05) and girls (P < 0.05) being most affected. Breast-feeding did not reduce the number of NoV infections. An important proportion (57%) of NoV-infected children were coinfected with diarrheagenic Escherichia coli. A significant proportion (18/31) of NoV-positive children with dehydration required intravenous rehydration. Nucleotide sequence analysis (38/65) of the N-terminal and shell region in the capsid gene revealed that at least six genotypes (GI.4, GII.2, GII.4, GII.7, GII.17, and a potentially novel cluster termed "GII.18-Nica") circulated during the study period, with GII.4 virus being predominant (26/38). The majority (20/26) of those GII.4 strains shared high nucleotide homology (99%) with the globally emerging Hunter strain. The mean viral load was approximately 15-fold higher in children infected with GII.4 virus than in those infected with other G.II viruses, with the highest viral load observed for the group of children infected with GII.4 and requiring intravenous rehydration. This study, the first of its type from a Central American country, suggests that NoV is an important etiological agent of acute diarrhea among children of <2 years of age in Nicaragua.
