    This paper examines Land Use and Land Cover (LULC) transition probabilities and its implications for Kumasi Metropolis using remote sensing image analysis technique. Methods used for the study include sub-setting of satellite images for the metropolis using the metropolitan shapefile boundary and classification of the images using maximum likelihood image classification algorithm. A Markov Model was applied to predict probabilities of LULC changes in 15 years (2016 - 2031). Study results show the probability of urban lands changing to agricultural land as low and so is the probability of farmland transitioning to urban land use. Vegetation however shows a high probability of change to built-up area while the likelihood of change from water to other land cover types is not a possibility. The study recommends enforcement of relevant land use policies backed by vigorous public education to make sustainable urban land use in the Metropolis a reality. Also, vertical rather than horizontal construction of buildings could stem the sprawling city

    Knowledge of thermophysical properties is essential to the food processing industries. The properties are useful in modeling of thermal behavior of seeds during processing operations such as frying, baking, boiling fermentation and drying. To this end, the thermo physical properties (bulk density, porosity, surface area, thermal conductivity, thermal diffusivity and specific heat capacity) of brown variety tigernut (Cyperus esculentus) were investigated as a function of moisture content. In this study, thermal conductivity and specific heat capacity were determined by transient state heat transfer (line heat source) and mixture methods respectively, whereas, thermal diffusivity, bulk density, porosity and surface area were determined using formula methods. The evaluation was conducted at 5 moisture levels (20, 25, 30, 35 and 40% w.b) with 5 replications. The thermal conductivity and diffusivity increased from 0.03Wm-1k-1 to 0.13Wm-1k-1 and from 7.24 x 10-7m2s-1 to 11.06 x 10-7 m2s-1 as the moisture content increased from 20 to 40% respectively. The specific heat increased from 10.55 Jkg-1K-1 to 18.75 Jkg-1K-1, while the bulk density and surface area showed an increase from 421.40 kg/m3 to 639.80 kg/m3 and from 197.26 mm2 to 413.21 mm2 as moisture content increased. However, porosity decreased in value from 61.84 to 32.33% with an increase in moisture. Moisture content variation was statistically significant (p<0.05) on all properties. The obtained results will find use in the selection of suitable methods for processing of tigernut products, in a quality assessment of optimal modes of technological processes, and in the development of modern processing and handling equipment

    Abstract Background Despite significant improvements, postpartum family planning uptake remains low for women in sub-Saharan Africa. Transmitting family planning education in a comprehensible way during antenatal care (ANC) has the potential for long-term positive impact on contraceptive use. We followed women for one-year postpartum to examine the uptake and continuation of family planning following enrollment in group versus individual ANC. Methods A longitudinal, prospective cohort design was used. Two hundred forty women were assigned to group ANC (n = 120) or standard, individual care (n = 120) at their first ANC visit. Principal outcome measures included intent to use family planning immediately postpartum and use of a modern family planning method at one-year postpartum. Additionally, data were collected on intended and actual length of exclusive breastfeeding at one-year postpartum. Pearson chi-square tests were used to test for statistically significant differences between group and individual ANC groups. Odds ratios and adjusted odds ratios were calculated using logistic regression. Results Women who participated in group ANC were more likely to use modern and non-modern contraception than those in individual care (59.1% vs. 19%, p < .001). This relationship improved when controlled for intention, age, religion, gravida, and education (AOR = 6.690, 95% CI: 2.724, 16,420). Women who participated in group ANC had higher odds of using a modern family planning method than those in individual care (AOR = 8.063, p < .001). Those who participated in group ANC were more likely to exclusively breastfeed for more than 6 months than those in individual care (75.5% vs. 50%, p < .001). This relationship remained statistically significant when adjusted for age, religion, gravida, and education (AOR = 3.796, 95% CI: 1.558, 9.247). Conclusions Group ANC has the potential to be an effective model for improving the uptake and continuation of post-partum family planning up to one-year. Antenatal care presents a unique opportunity to influence the adoption of postpartum family planning. This is the first study to examine the impact of group ANC on family planning intent and use in a low-resource setting. Group ANC holds the potential to increase postpartum family planning uptake and long-term continuation. Trial registration Not applicable. No health related outcomes reported.https://deepblue.lib.umich.edu/bitstream/2027.42/146750/1/12978_2018_Article_644.pd

    Quality of basic maternal care functions in health facilities of fi ve African countries: an analysis of national health system surveys

    Get PDF
    Background Global eff orts to increase births at health-care facilities might not reduce maternal or newborn mortality if quality of care is insuffi cient. However, little systematic evidence exists for the quality at health facilities caring for women and newborn babies in low-income countries. We analysed the quality of basic maternal care functions and its association with volume of deliveries and surgical capacity in health-care facilities in fi ve sub-Saharan African countries. Methods In this analysis, we combined nationally representative health system surveys (Service Provision Assessments by the Demographic and Health Survery Programme) with data for volume of deliveries and quality of delivery care from Kenya, Namibia, Rwanda, Tanzania, and Uganda. We measured the quality of basic maternal care functions in delivery facilities using an index of 12 indicators of structure and processes of care, including infrastructure and use of evidence-based routine and emergency care interventions. We regressed the quality index on volume of births and confounders (public or privately managed, availability of antiretroviral therapy services, availability of skilled staffi ng, and country) stratifi ed by facility type: primary (no caesarean capacity) or secondary (has caesarean capacity) care facilities. The Harvard University Human Research Protection Program approved this analysis as exempt from human subjects review. Findings The national surveys were completed between April, 2006, and May, 2010. Our sample consisted of 1715 (93%) of 1842 health-care facilities that provided normal delivery service, after exclusion of facilities with missing (n=126) or invalid (n=1) data. 1511 (88%) study facilities (site of 276 965 [44%] of 622 864 facility births) did not have caesarean section capacity (primary care facilities). Quality of basic maternal care functions was substantially lower in primary (index score 0·38) than secondary care facilities (0·77). Low delivery volume was consistently associated with poor quality, with diff erences in quality between the lowest versus highest volume facilities of –0·22 (95% CI –0·26 to –0·19) in primary care facilities and –0·17 (–0·21 to –0·11) in secondary care facilities. Interpretation More than 40% of facility deliveries in these fi ve African countries occurred in primary care facilities, which scored poorly on basic measures of maternal care quality. Facilities with caesarean section capacity, particularly those with birth volumes higher than 500 per year, had higher scores for maternal care quality. Low-income and middle-income countries should systematically assess and improve the quality of delivery care in health facilities to accelerate reduction of maternal and newborn deaths

    The aim of this study is to determine the proportion of women with the physical sign of stress urinary incontinence in a sample of Ghanaian women. Two hundred randomly selected women from attendants at a convenience selected ultrasound clinic were interviewed about symptoms of urinary incontinence. A paper towel test was performed to objectively demonstrate the physical sign of stress urinary incontinence as leakage on coughing. Forty-two percent of the women had a positive paper towel test. The two major symptoms reported by the women with positive paper towel test were (1) loss of urine while waiting to use the toilet (48.2%) and (2) loss of urine on coughing (43.4%) in daily life. The physical sign of stress urinary incontinence could be present in up to 42% of Ghanaian women.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/45851/1/192_2005_Article_62.pd

    Improving health literacy through group antenatal care: a prospective cohort study

    Full text link
    Abstract Background To examine whether exposure to group antenatal care increased women’s health literacy by improving their ability to interpret and utilize health messages compared to women who received standard, individual antenatal care in Ghana. Methods We used a prospective cohort design. The setting was a busy urban district hospital in Kumasi, the second most populous city in Ghana. Pregnant women (N = 240) presenting for their first antenatal visit between 11 and 14 weeks gestation were offered participation in the study. A 27% drop-out rate was experienced due to miscarriage, transfer or failure to return for follow-up visits, leaving 184 women in the final sample. Data were collected using an individual structured survey and medical record review. Summary statistics as well as two sample t-tests or chi-square were performed to evaluate the group effect. Results Significant group differences were found. Women participating in group care demonstrated improved health literacy by exhibiting a greater understanding of how to operationalize health education messages. There was a significant difference between women enrolled in group antenatal care verses individual antenatal care for preventing problems before delivery, understanding when to access care, birth preparedness and complication readiness, intent to use a modern method of family planning postpartum, greater understanding of the components of breastfeeding and lactational amenorrhea for birth spacing, and intent for postpartum follow-up. Conclusion Group antenatal care as compared to individual care offers an opportunity to increase quality of care and improve maternal and newborn outcomes. Group antenatal care holds the potential to increase healthy behaviors, promote respectful maternity care, and generate demand for services. Group ANC improves women’s health literacy on how to prevent and recognize problems, prepare for delivery, and care for their newborn.https://deepblue.lib.umich.edu/bitstream/2027.42/137701/1/12884_2017_Article_1414.pd

    Sexual and Reproductive Health Research and Research Capacity Strengthening in Africa: Perspectives from the region.

    Get PDF
    Developing the capacity to effectively carry out public health research is an integral part of health systems at both the national and global levels and strengthening research capacity is recognized as an approach to better health and development in low- and middle-income countries (LMICs). Especially fields such as sexual and reproductive health (SRH) would require inter-disciplinary teams of researchers equipped with a range of methodologies to achieve this. In November 2013, as part of the International Family Planning Conference in Addis Ababa, Ethiopia, a group of African researchers came together to discuss the gaps and strategies to improve sexual and reproductive health research and research capacity strengthening in Africa. This commentary summarizes the three broad areas where the issues and proposed solutions have concentrated around: 1) Addressing research gaps that are most relevant to policies and programmes in SRH, 2) Carrying out high quality and collaborative research, and 3) Translating research findings into SRH policies and programmes. Even though the focus of the discussions was Africa, the issues and proposed solutions can also be applied to other regions facing a high burden of disease with limited resources. The time is now and these can be achieved through synergistic commitment of African and global researchers, funders and organization

    Optimism/pessimism and health-related quality of life during pregnancy across three continents: a matched cohort study in China, Ghana, and the United States

    Get PDF
    <p>Abstract</p> <p>Background</p> <p>Little is known about how optimism/pessimism and health-related quality of life compare across cultures.</p> <p>Methods</p> <p>Three samples of pregnant women in their final trimester were recruited from China, Ghana, and the United States (U.S.). Participants completed a survey that included the Life Orientation Test - Revised (LOT-R, an optimism/pessimism measure), the Short Form 12 (SF-12, a quality of life measure), and questions addressing health and demographic factors. A three-country set was created for analysis by matching women on age, gestational age at enrollment, and number of previous pregnancies. Anovas with post-hoc pairwise comparisons were used to compare results across the cohorts. Multivariate regression analysis was used to create a model to identify those variables most strongly associated with optimism/pessimism.</p> <p>Results</p> <p>LOT-R scores varied significantly across cultures in these samples, with Ghanaian pregnant women being the most optimistic and least pessimistic and Chinese pregnant women being the least optimistic overall and the least pessimistic in subscale analysis. Four key variables predicted approximately 20% of the variance in overall optimism scores: country of origin (p = .006), working for money (p = .05); level of education (p = .002), and ever being treated for emotional issues with medication (p < .001). Quality of life scores also varied by country in these samples, with the most pronounced difference occurring in the vitality measure. U.S. pregnant women reported far lower vitality scores than both Chinese and Ghanaian pregnant women in our sample.</p> <p>Conclusion</p> <p>This research raises important questions regarding what it is about country of origin that so strongly influences optimism/pessimism among pregnant women. Further research is warranted exploring underlying conceptualization of optimism/pessimism and health related quality of life across countries.</p
