The Impact of High Lending Rates on Borrowers’ Ability to pay Back Loans in the Tamale Metropolis
The main purpose of the research was to find out the impact of high lending rates on borrower’s ability to pay back loans in the Tamale Metropolis. Cross- sectional survey method was adopted. Structured questionnaires were distributed to respondents within Tamale Metropolis to solicit their views concerning lending rates. 200 questionnaires were distributed but 101 respondents were drawn for data collection. Non-probability sampling method basically random sampling and convenience sampling were used.At the end of the study, it was found out that the lending rate that is deemed acceptable by both borrowers and lenders was 25%. On the other hand, the respondents (borrowers) were also of the view that the current lending rate was rather too high. It was also found out that high lending rates affected borrowers’ ability to pay back because they cannot make enough returns from their businesses to service their loans. Based on this notion, the borrowers further said that high lending rates affected their businesses negatively in the sense that they are not able to make enough profits to grow their businesses which is the primary reason why they opted for the loan facility. It can be concluded that lending rates impact on the operations of businesses whether high or low. Central Bank as well as all financial institutions that have the ability to lend money should adopt Interest Rate Reduction Refinancing Loan (IRRRL) into their business operation so that borrowers can invest to yield enough profit to service their loans and also make some profit for growth. Keywords: Lending Rates, Loan Facility, Financial Institutions and Interest Rate Reduction Refinancing Loan (IRRRL
Obesity in pregnancy: Epidemiology and development of a lifestyle intervention
Obesity, defined as a body mass index of 30 kg/m2 or more, has reached epidemic proportions globally, with more than one-and-a-half billion adults overweight and at least 500 million clinically obese. The prevalence of obesity in the UK has increased by over 300% since 1980. In the UK 24% of adult women are obese and one in six women at an antenatal booking clinic is obese.
Obesity has the potential for several detrimental effects on both the mother and the baby. Obese mothers are more likely to develop pre-eclampsia and eclampsia, gestational diabetes and venous thromboembolism. In addition, obese pregnant women are more likely to be induced, often resulting in complicated deliveries such as emergency Caesarean section and shoulder dystocia. Obesity significantly increases the risk of maternal mortality during or after pregnancy. Babies born to obese mothers are at an increased risk of congenital abnormalities, preterm deliveries and stillbirth, and children exposed to maternal obesity are at an increased risk of developing metabolic syndrome in later life.
The aim of this work was to assess the extent and potential for the prevention of adverse impacts of obesity in pregnancy. The specific objectives were to: summarise the literature on maternal obesity and adverse pregnancy outcome; perform an epidemiological analysis using local data of obesity in pregnancy; conduct a systematic review of existing evidence on lifestyle interventions for obesity in pregnancy; and to develop and evaluate a multi-component pilot study for a community-based intervention for maternal obesity in South London.
Analysis of delivery data from South London between January 2004 and May 2012 showed the overall prevalence of maternal obesity to be 15%, with considerable variation by ethnic group. There was a strong association between rising body mass index and risk of adverse pregnancy outcome, especially diabetes. The effect of obesity on diabetes in pregnancy was more pronounced in Asians and Orientals compared to other ethnic groups. Calculations of population attributable risk fractions showed that, if we were able to prevent obesity before pregnancy in this population, around one-third of diabetes in pregnancy could be prevented. The data alluded to the fact that the benefit of obesity reduction would be greater in Blacks than in other ethnic groups because of the higher prevalence of obesity in this group.
A complex community-based lifestyle intervention called the Community Activity and Nutrition (CAN) programme was developed for delivery by health trainers in children’s/Sure Start centres. The research showed that it is feasible to deliver the CAN intervention in children’s/Sure Start centres (Effra in Brixton, Jessop in Herne Hill and Jubilee in Tulse Hill) in an Inner London socially deprived community. The pilot study encountered problems with recruitment resulting from understaffing and lack of participant time. However, once recruited, retention on the programme was good. There was some evidence that the intervention improved selected clinical outcomes. Further work is ongoing to establish the clinical and cost effectiveness of the intervention. If CAN is shown to be clinically effective and cost-effective, the translation of this research and adoption by policy makers into the wider community may help to ameliorate the adverse outcomes associated with obesity in pregnancy
Birth Weights in Sickle Cell Disease Pregnancies: A Cohort Study.
Pregnancy in women with Sickle Cell Disease (SCD) has been linked with an increased incidence of adverse foetal outcomes when compared to women without haemoglobinopathies (HbAA). There's a paucity of data into foetal outcomes for infants born to women with SCD. Customised growth charts have been demonstrated to be better than population-based growth charts at identifying unhealthy small babies. We analysed the mean birth weight and customised birth weight centiles of infants born to mothers with SCD versus mothers with HbAA genotype, to quantify the risk of having a smaller baby. Birth weight and birth weight centiles were analysed for 88 women with SCD (50 HbSS; 38 HbSC) and 176 controls (HbAA). Statistically significant differences were seen in the mean birth weight (P value = 0.004) and the mean birth weight centiles (P value = 0.016). We conclude that SCD is a risk factor for having a smaller baby
Risk of Adverse Obstetric and Neonatal Outcomes by Maternal Age: Quantifying Individual and Population Level Risk Using Routine UK Maternity Data.
OBJECTIVE: The objective of this study was to investigate whether moderately increased maternal age is associated with obstetric and neonatal outcome in a contemporary population, and to consider the possible role of co-morbidities in explaining any increased risk. STUDY DESIGN: Secondary analysis of routinely collected data from a large maternity unit in London, UK. Data were available on 51,225 singleton deliveries (≥22 weeks) occurring to women aged ≥20 between 2004 and 2012. Modified Poisson regression was used to estimate risk ratios for the association between maternal age and obstetric and neonatal outcome (delivery type, postpartum haemorrhage, stillbirth, low birthweight, preterm birth, small for gestational age, neonatal unit admission), using the reference group 20-24 years. Population attributable fractions were calculated to quantify the population impact. RESULTS: We found an association between increasing maternal age and major postpartum haemorrhage (≥1000ml blood loss) (RR 1.36 95% CI 1.18-1.57 for age 25-29 rising to 2.41 95% CI 2.02-2.88 for age ≥40). Similar trends were observed for caesarean delivery, most notably for elective caesareans (RR 1.64 95% CI 1.36-1.96 for age 25-29 rising to 4.94 95% CI 4.09-5.96 for age ≥40). There was evidence that parity modified this association, with a higher prevalence of elective caesarean delivery in older nulliparous women. Women aged ≥35 were at increased risk of low birthweight and preterm birth. We found no evidence that the risk of stillbirth, small for gestational age, or neonatal unit admission differed by maternal age. CONCLUSIONS: Our results suggest a gradual increase in the risk of caesarean delivery and postpartum haemorrhage from age 25, persisting after taking into account maternal BMI, hypertension and diabetes. The risk of low birthweight and preterm birth was elevated in women over 35. Further research is needed to understand the reasons behind the high prevalence of elective caesarean delivery in nulliparous older mothers
Lifestyle interventions for overweight and obese pregnant women to improve pregnancy outcome: systematic review and meta-analysis
BACKGROUND: Overweight and obesity pose a big challenge to pregnancy as they are associated with adverse maternal and perinatal outcome. Evidence of lifestyle intervention resulting in improved pregnancy outcome is conflicting. Hence the objective of this study is to determine the efficacy of antenatal dietary, activity, behaviour or lifestyle interventions in overweight and obese pregnant women to improve maternal and perinatal outcomes. METHODS: A systematic review and meta-analyses of randomised and non-randomised clinical trials following prior registration (CRD420111122 http://www.crd.york.ac.uk/PROSPERO) and PRISMA guidelines was employed. A search of the Cochrane Library, EMBASE, MEDLINE, CINAHL, Maternity and Infant care and eight other databases for studies published prior to January 2012 was undertaken. Electronic literature searches, study selection, methodology and quality appraisal were performed independently by two authors. Methodological quality of the studies was assessed according to Cochrane risk of bias tool. All appropriate randomised and non-randomised clinical trials were included while exclusions consisted of interventions in pregnant women who were not overweight or obese, had pre-existing diabetes or polycystic ovarian syndrome, and systematic reviews. Maternal outcome measures, including maternal gestational weight gain, gestational diabetes and Caesarean section, were documented. Fetal outcomes, including large for gestational age and macrosomia (birth weight > 4 kg), were also documented. RESULTS: Thirteen randomised and six non-randomised clinical trials were identified and included in the meta-analysis. The evidence suggests antenatal dietary and lifestyle intervention in obese pregnant women reduces maternal pregnancy weight gain (10 randomised clinical trials; n = 1228; -2.21 kg (95% confidence interval -2.86 kg to -1.59 kg)) and a trend towards a reduction in the prevalence of gestational diabetes (six randomised clinical trials; n = 1,011; odds ratio 0.80 (95% confidence interval 0.58 to 1.10)). There were no clear differences reported for other outcomes such as Caesarean delivery, large for gestational age, birth weight or macrosomia. All available studies were assessed to be of low to medium quality. CONCLUSION: Antenatal lifestyle intervention is associated with restricted gestational weight gain and a trend towards a reduced prevalence of gestational diabetes in the overweight and obese population. These findings need to be interpreted with caution as the available studies were of poor to medium quality
A Systematic Review and Meta-Analysis of Non-Invasive Prenatal Diagnosis (NIPD) of Sickle Cell Disease (SCD)
Introduction: Sickle cell disease (SCD) is a genetically inherited, recessive mutation of the haemoglobin ?S-gene. Each year, over 300,000 babies are born with SCD, which will have a significant impact on their quality of life and average life expectancy. Currently, for SCD to be tested prenatally, foetal DNA is extracted by amniocentesis, chorionic villus sampling or cordocentesis, and then analysed by polymerase chain reaction (PCR), for instance. These procedures increase the risk of foetal miscarriage by less than 0.5%. SCD may, however, be tested non-invasively using cell-free foetal DNA (cffDNA), which is extracted from maternal blood plasma. In this study, the current accuracy of using cffDNA testing for non-invasive prenatal diagnosis (NIPD) of SCD will be shown.
Methods: Using databases such as PubMed, Web of Science and Scopus, this study systematically reviewed existing studies pertaining to the use of cffDNA maternal blood samples for non-invasive prenatal testing (NIPT) or diagnosis (NIPD) for SCD in patients who were at risk of having a baby with SCD. The data collected from the systematic review of the studies was statistically analysed in the form of a meta-analysis, describing the proportion of correct diagnosis results for this method of prenatal testing.
Results: Of over 3,600 papers identified from the database searches, only five studies contained data pertaining to the use of cffDNA for prenatal testing of SCD and conformed to the inclusion criteria set out by this study. Collectively, these data showed an average of 81.30% accuracy of diagnosis when using cffDNA to test for SCD, with 18.70% of foetuses incorrectly diagnosed. These data were compiled as a Forest Plot meta-analysis.
Conclusion: CffDNA for non-invasive prenatal SCD diagnosis appears to have the potential to be an accurate technique for the testing of this genetic disease, despite not currently indicating a proportion of correct diagnosis results which would encourage the technique for clinical implementation. Whilst there are currently very limited data on the use of this technique for the specific testing of SCD, there is great opportunity for further research into the standardisation and clinical application of this procedure
Maternal BMI and diabetes in pregnancy: Investigating variations between ethnic groups using routine maternity data from London, UK.
OBJECTIVE: To investigate the ethnicity-specific association between body mass index (BMI) and diabetes in pregnancy, with a focus on the appropriateness of using BMI cut-offs to identify pregnant women at risk of diabetes. STUDY DESIGN: Analysis of routinely-collected data from a maternity unit in London, UK. Data were available on 53 264 women delivering between 2004 and 2012. Logistic regression was used to explore the association between diabetes in pregnancy and BMI among women of different ethnicities, and adjusted probability estimates were used to derive risk equivalent cut-offs. ROC curve analysis was used to assess the performance of BMI as a predictor of diabetes in pregnancy. RESULTS: The prevalence of diabetes in pregnancy was 2.3% overall; highest in South and East Asian women (4.6% and 3.7%). In adjusted analysis, BMI category was strongly associated with diabetes in all ethnic groups. Modelled as a continuous variable with a quadratic term, BMI was an acceptable predictor of diabetes according to ROC curve analysis. Applying a BMI cut-off of 30 kg/m2 would identify just over half of Black women with diabetes in pregnancy, a third of White (32%) and South Asian (35%) women, but only 13% of East Asian women. The 'risk equivalent' (comparable to 30 kg/m2 in White women) threshold for South Asian and East Asian women was approximately 21 kg/m2, and 27.5 kg/m2 for Black women. CONCLUSIONS: This study suggests that current BMI thresholds are likely to be ineffective for diabetes screening in South and East Asian women, as many cases of diabetes will occur at low BMI levels. Our results suggest that East Asian women appear to face a similarly high risk of diabetes to South Asian women. Current UK guidelines recommend diabetes screening should be offered to all pregnant South Asian women; extending this recommendation to include women of East Asian ethnicity may be appropriate
Preferences for prenatal diagnosis of sickle-cell disorder: A discrete choice experiment comparing potential service users and health-care providers
BACKGROUND: Non-invasive prenatal diagnosis (NIPD) for sickle-cell disorder (SCD) is moving closer to implementation and studies considering stakeholder preferences are required to underpin strategies for offering NIPD in clinical practice. OBJECTIVE: Determine service user and provider preferences for key attributes of prenatal diagnostic tests for SCD and examine views on NIPD. METHOD: A questionnaire that includes a discrete choice experiment was used to determine the preferences of service users and providers for prenatal tests that varied across three attributes: accuracy, time of test and risk of miscarriage. RESULTS: Adults who were carriers of SCD or affected with the condition (N=67) were recruited from haemoglobinopathy clinics at two maternity units. Health professionals, predominately midwives, who offer antenatal care (N=62) were recruited from one maternity unit. No miscarriage risk was a key driver of decision making for both service users and providers. Service providers placed greater emphasis on accuracy than service users. Current uptake of invasive tests was 63%, whilst predicted uptake of NIPD was 93.8%. Many service users (55.4%) and providers (52.5%) think pressure to have prenatal testing will increase when NIPD for SCD becomes available. CONCLUSIONS: There are clear differences between service users and health professionals' preferences for prenatal tests for sickle-cell disorder. The safety of NIPD is welcomed by parents and uptake is likely to be high. To promote informed choice, pretest counselling should be balanced and not exclusively focused on test safety. Counselling strategies that are sensitive to feelings of pressure to test will be essential
Interpregnancy weight change and adverse pregnancy outcomes: a systematic review and meta-analysis.
OBJECTIVES: To evaluate the effect of interpregnancy body mass index (BMI) change on pregnancy outcomes, including large-for-gestational-age babies (LGA), small-for-gestational-age babies (SGA), macrosomia, gestational diabetes mellitus (GDM) and caesarean section (CS). DESIGN: Systematic review and meta-analysis of observational cohort studies. DATA SOURCES: Literature searches were performed across Cochrane, MEDLINE, EMBASE, CINAHL, Global Health and MIDIRS databases. STUDY SELECTION: Observational cohort studies with participants parity from 0 to 1. MAIN OUTCOME MEASURES: Adjusted ORs (aORs) with 95% CIs were used to evaluate the association between interpregnancy BMI change on five outcomes. RESULTS: 925 065 women with singleton births from parity 0 to 1 were included in the meta-analysis of 11 studies selected from 924 identified studies. A substantial increase in interpregnancy BMI (>3 BMI units) was associated with an increased risk of LGA (aOR 1.85, 95% CI 1.71 to 2.00, p<0.001), GDM (aOR 2.28, 95% CI 1.97 to 2.63, p<0.001), macrosomia (aOR 1.54, 95% CI 0.939 to 2.505) and CS (aOR 1.72, 95% CI 1.32 to 2.24, p<0.001) compared with the reference category, and a decreased risk of SGA (aOR 0.83, 95% CI 0.70 to 0.99, p=0.044). An interpregnancy BMI decrease was associated with a decreased risk of LGA births (aOR 0.70, 95% CI 0.55 to 0.90, p<0.001) and GDM (aOR 0.80, 95% CI 0.62 to 1.03), and an increased risk of SGA (aOR 1.31, 95% CI 1.06 to 1.63, p=0.014). Women with a normal BMI (<25kg/m2) at first pregnancy who have a substantial increase in BMI between pregnancies had a higher risk of LGA (aOR 2.10, 95% CI 1.93 to 2.29) and GDM (aOR 3.10, 95% CI 2.74 to 3.50) when compared with a reference than women with a BMI ≥25 kg/m2 at first pregnancy. CONCLUSIONS: Gaining weight between pregnancies increases risk of developing GDM, CS and LGA, and reduces risk of SGA in the subsequent pregnancy. Losing weight between pregnancies reduces risk of GDM and LGA and increases risk of SGA. Weight stability between first and second pregnancy is advised in order to reduce risk of adverse outcomes.

Pulmonary complications for women with sickle cell disease in pregnancy: systematic review and meta-analysis.
BACKGROUND: Sickle cell disease (SCD) is a multisystem disease characterised by vaso-occlusive crisis, chronic anaemia and a shorter lifespan. More patients with SCD are living till reproductive age and contemplating pregnancy. Pulmonary complications in pregnancy are significant causes of maternal morbidity and mortality but yet this has not been systematically quantified. A systematic review and meta-analysis were conducted to quantify the association between SCD and pulmonary complications in pregnancy. METHODS: MEDLINE, EMBASE, Web of Science, Cochrane and Maternity and Infant Care databases were searched for publications between January 1998 and April 2019. Observational studies involving at least 30 participants were included. Random-effects models were used for statistical meta-analysis. FINDINGS: Twenty-two studies were included in the systematic review and 18 in the quantitative analysis. The meta-analysis included 3964 pregnancies with SCD and 336 559 controls. Compared with women without SCD, pregnancies complicated by SCD were at increased risk of pulmonary thromboembolism (relative risk (RR) 7.74; 95% CI 4.65 to 12.89). The estimated prevalence of acute chest syndrome and pneumonia was 6.46% (95% CI 4.66% to 8.25%), with no significant difference between the HbSS and HbSC genotypes (RR 1.42; 95% CI 0.90 to 2.23). INTERPRETATION: This meta-analysis highlighted a strong association between SCD and maternal pulmonary complications. Understanding the risks of and the factors associated with pulmonary complications would aid preconceptual counselling and optimal management of the condition in pregnancy, thereby reducing associated maternal morbidity and mortality.
