Misconceptions exist in Nigeria about the effects of hormonal contraceptives on weight, which may have negative effects on contraceptive use. Data from case notes of clients attending the reproductive health centre at the Ahmadu Bello University Teaching Hospital, Zaria, between 1993 and 1995, were analysed to determine the effects of hormonal contraceptives on body weight, comparing them to clients using intrauterine contraceptive devices. Weight changes were not significantly different in clients using hormonal contraceptives and those using intrauterine contraceptive devices. This information will be beneficial in contraceptive counselling for clients in this environment and provide a baseline for further research.  相似文献

Women are increasingly being recognised as equal partners in development. However, there is a growing awareness that negative health, social and economic consequences act as barriers in their efforts to contribute to sustainable development. Consequently, to fully harness the potentials of women in this regard, these barriers have to be addressed. This paper utilises qualitative data collected as part of an intervention programme designed to increase access to reproductive health information/services and economic resources among young women in Osogbo, Nigeria. The aim was to provide reproductive health information and training in basic business skills and micro-credit facilities to enable beneficiaries to establish private businesses. Findings from the study highlight the importance of the relationship between female education, access to economic resources as a means of furthering empowerment of women especially in terms of their reproductive behaviour. The paper argues that increased access to resources is a major factor toward ensuring the much desired empowerment.  相似文献

The purpose of this study is to demonstrate the importance of community mobilization in the uptake of a health intervention, namely, community-based distribution of misoprostol to prevent postpartum hemorrhage. Community mobilization to increase access to misoprostol for postpartum hemorrhage prevention was implemented in northwestern Nigeria in 2009. Theories of community participation and the current near-epidemic maternal mortality conditions underpin an approach using modest levels of community involvement. The study was undertaken in five communities around Zaria, Nigeria. Community leaders and selected community members participated in a series of dialogs. Additionally, community education, information and dramas sessions were held. Twenty nine community oriented resource persons (CORPs), 27 drug keepers and 41 traditional birth attendants (TBAs) were involved in the intervention. Postpartum interviews were used to assess the impact of community mobilization efforts and to track use of misoprostol. Multiple logistic regression was used to examine the association between correct use and receiving information regarding misoprostol from TBAs or CORPs. A total of 1875 women were enrolled in the study in 2009. Most women delivered at home (95%) and skilled attendance at delivery was low (7%). Community mobilization efforts reached most women with information about postpartum hemorrhage and misoprostol (88%), resulting in high comprehension of intervention messages. Women identified TBAs and CORPs as the single most important source of information about misoprostol 41% and 31% of the time, respectively. Availability of misoprostol at the community level gave 79% of enrolled women some protection against postpartum hemorrhage which they otherwise would not have had. Although high level community participation in health care interventions is the ideal, this study suggests that even in circumstances where only modest levels of participation can realistically be achieved, community mobilization can have a significant impact on the successful distribution and uptake of a potentially life-saving health intervention, in turn helping promote policy change.  相似文献

Custard powder is a dry-formulated food product primarily made from imported corn starch in developing countries. To reduce over-dependence on corn starch, this study investigated its replacement with yellow-fleshed cassava root starch (YfCRS) in custard powder formulation. Response surface methodology was used to develop an optimized cassava starch-based custard powder based on various combinations of YfCRS (90–98%) and whole egg powder (WEP) (2–10%). The result showed that the blends of YfCRS and WEP led to custard powder with wide functional, physicochemical, chemical, and micronutrient properties, with sensorily acceptable gruel. The second order response surface regression model accurately predicted most of these quality parameters (R2 > 0.90). The optimum formulation achieved to produce an acceptable custard was 90% YfCRS and 6.07% WEP. Therefore, this study showed that YfCRS might be a very good replacement for corn starch in the production of an acceptable custard.  相似文献

Several studies have reported the synthesis of carbon nanoparticles (CNPs) by various methods. In this study, an easy one-step process to unsheathe CNPs from date palm fronds through a top-down ball milling method has been reported. The CNPs were characterized using various spectroscopic and microscopic methods to determine their structural and morphological features, optical properties, crystallinity, physicochemical properties, and particle stability. Transmission electron microscopy (TEM) revealed that the obtained CNPs'' size ranged from 4 to 22 nm in a crystalline form. Scanning electron microscopy (SEM) confirmed their spherical shape, while the maximum photoluminescence (PL) intensity was recorded at 464 nm when excited at 375 nm. The unsheathed CNPs produced a good quantum yield (QY) of 3.24%. Furthermore, the CNPs exhibited high Raman ratios of ID/IG and I2D/IG with values of 0.59 and 0.04, respectively, verifying their multilayer crystalline graphitic nature. These Raman ratios also agree with the X-ray diffractometry (XRD) results. The CNPs'' sp2 and sp3 carbon bonds were confirmed by X-ray photoelectron spectroscopy (XPS), with oxygen on the surface forming carboxyl and carbonyl groups with no other observable impurities. Furthermore, the extracted CNPs showed excellent PL properties for up- and down-conversion. These properties are exemplary for low-cost biomass with potential applications in biomedicine. Therefore, the extracted CNPs reported in this study have potential applications in optical imaging.
