Prevalence and Risk Factors for Diabetes Mellitus in A State in South East Nigeria: Results of a Population Based House to House Survey.

BACKGROUND: Population based studies on diabetes mellitus (DM) are scarce in Nigeria. INTRODUCTION: This was a population-based house to house survey aimed at determining the prevalence of DM and assessing the risk factors associated with DM in a state in Southeast Nigeria. METHODS: This was a cross-sectional observational study in which 1680 adults were recruited using a multistage sampling method to randomly select not more than two suitable participants of both sex in each household from four enumeration areas (EAs) in each local government area (LGA) and the three senatorial zones in the state. A modified World Health Organization (WHO) Stepwise Approach to Surveillance questionnaire was used for data collection and random blood glucose (RBG) was measured after anthropometric assessment. Test statistics used were chi-square, t-test, and logistic regression. RESULTS: The overall prevalence of DM in this study was 3.3%. A positive family history of DM was significantly higher in patients with diabetes: 18.2% vs. 9.6% (p=0.036). The mean (SD) of weight, body mass index (BMI), hip circumference (HC) and waist circumference (WC) were significantly higher in patients with DM(p=0.001,<0.001,<0.001,<0.001, respectively).The odd ratio (95% CI) of a person>35years developing DM was 3.89(1.11-13.60). The OR (95% CI) for waist-hip ratio (WHR) was 3.04 (1.02-9.03) and family history of DM had an OR of 2.62(0.88-6.50). The odd of developing DM is positively associated with age>35years, increased WHR, WC, family history of DM, BMI>25Kg/m2, and HC. The odd of developing DM was negatively associated with smoking. CONCLUSION: The prevalence of DM in this study was 3.3%. A BMI>25 kg/m2, WHR >0.85, family history of DM, HC, and older age were associated with significantly higher prevalence.

Prevalence and Predictors of Chronic Kidney Disease in a Semiurban Community in Lagos.

BACKGROUND AND OBJECTIVES: The prevalence of noncommunicable diseases like chronic kidney disease is on the rise in third-world countries. In Nigeria and most sub-Saharan African countries, there is dearth of community-based studies on prevalence and predictors of chronic kidney disease, prompting us to undertake this study. MATERIALS AND METHODS: This was a cross-sectional study, aimed at ascertaining the prevalence and predictors of chronic kidney disease (CKD) in a semiurban community in Lagos, Southwest Nigeria. The study's subjects were recruited from Agbowa community in Ikosi-Ejirin Local Council Development Area of Lagos state. The community was randomly selected. Questionnaires were used to obtain relevant information from the subjects. Body mass index, anthropometric measurements, and other relevant data were also collected. RESULTS: CKD was observed in 30 subjects given prevalence of 7.5% in the community. Nine out of the 30 subjects (30%) with CKD were males, while 21 (70%) subjects were females. The prevalence of CKD was significantly higher in the female population. 28 of the subjects with CKD were in stage 3, while 2 of the subjects with CKD were in stage 4. Age, hypertension, and hyperuricemia were significantly associated with CKD. Using multiple logistic regression analysis, 4 variables predicted CKD in the study population. These were age (P =0.01, OR = 0. 274, CI = 0.102 - 0.739), hypertension (p = 0.011, OR = 0. 320, CI = 0.132 - 0.773), hyperuricemia (p=0.001, OR = 0.195, CI =0.083 - 0.461), and female sex (p = 0.009, OR = 3.775, CI = 1.401 - 10.17). CONCLUSION: The prevalence of CKD in the population is low compared with other studies from other parts of the country, and the predictors included age, hypertension, hyperuricemia, and female gender. This is the first community-based study in Nigeria to identify hyperuricemia as a risk factor for chronic kidney disease in the country.

Challenges with Insulin Use Among Patients with Type 2 Diabetes Mellitus: Focus on a Tertiary Healthcare Setting in South-East Nigeria.

BACKGROUND: Effective usage of insulin in the management of diabetes remains a challenge in developing countries like Nigeria. OBJECTIVE: The objective of this study is to document the pattern of insulin prescription, frequency, storage, common regimen used, and attendant problems associated with its use in patients with type 2 diabetes mellitus (T2DM). METHODS: This was a prospective, descriptive study in which consecutive T2DM patients seen at the medical out-patient clinic and medical wards and who fulfilled the criteria for inclusion were recruited. Participants provided information on their demographic characteristics, diabetes history, treatment and problems associated with treatment, type of insulin in use, number of daily injections, storage, method of insulin administration and problems associated with insulin use. Clinical examination was carried out basically to determine the anthropometric indices. RESULTS: About 84.3% have used insulin for less than 5 years. The thigh was the commonest site of insulin administration (95.3%). About 94.3% of subjects in this study store their insulin in a refrigerator. And Insulin dosing regimen ranged from less than once to four times daily while majority of patients (63%) were on twice daily insulin regimen. Insulin administration devices used were Insulin syringes 394 (98.5%) and Insulin pens 6 (1.5%). Thirty three percent of the subjects self inject insulin while about half of the study subjects (50.5%) receive insulin from a healthcare provider. The most common insulin used by patients was Mixed/ Premixed insulin (32.8%) and Regular/ Soluble insulin (38.8%). Hypoglycaemia was the most frequently documented problem encountered by subjects on insulin followed by weight gain. Majority of the study subjects (50.8%) practice self monitoring of blood glucose (SMBG). DISCUSSION: This study has demonstrated that majority of subjects with T2DM were on premixed insulin and that hypoglycaemia is the most common problem reported by patients. Insulin pens were not common among our study population.

Validation of Siriraj Stroke Score in southeast Nigeria.

The aim of the study is to validate the use of Siriraj Stroke Score (SSS) in the diagnosis of acute hemorrhagic and acute ischemic stroke in southeast Nigeria. This was a prospective study on validity of SSS in the diagnosis of stroke types in southeast Nigeria. Subjects diagnosed with stroke for whom brain computerized tomography (CT) scan was performed on admission were recruited during the study period. SSS was calculated for each subject, and the SSS diagnosis was compared with brain CT scan-based diagnosis. A total of 2,307 patients were admitted in the hospital medical wards during the study period, of whom 360 (15.6%) were stroke patients and of these, 113 (31.4%) adult subjects met the inclusion criteria. The mean age of the subjects was 66.5±2.6 years. The mean interval between ictus and presentation was 2.5±0.4 days. Ischemic stroke was confirmed by CT in 74 subjects; however, SSS predicted 60 (81.1%) of these subjects correctly (P<0.05). Hemorrhagic stroke was confirmed by CT in 39 subjects, and SSS predicted 36 (92.3%) of them correctly (P<0.05). In acute ischemic stroke, sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of SSS were 92%, 94%, 97%, 86%, and 93%, respectively, while in patients with hemorrhagic stroke, the corresponding percentages were 94%, 92%, 86%, 97%, and 93%, respectively. SSS is not reliable enough to clinically differentiate stroke types in southeast Nigeria to warrant interventions like thrombolysis in acute ischemic stroke.

Childhood mortality in federal medical centre umuahia, South eastern Nigeria.

OBJECTIVES: This study aimed to evaluate the mortality pattern in children seen at Federal Medical Centre Umuahia (FMCU) Abia state, South Eastern Nigeria. METHODS: A retrospective cross sectional descriptive study over a 5-year period from January 1, 2004 to December 31, 2008 using data retrieved from the hospital's medical records department. RESULTS: A total of 3,814 children were admitted in the hospital and 434 of them died giving a mortality rate of 11%. The mean age was 1.7 (Std D of 3.19). Two hundred and thirty eight of them were males while 196 of them were females giving a sex ratio of 1.2:1. Majority of the mortality (49%) occurred within 24 hours of admission. The major causes of death during neonatal period were birth asphyxia (34%), prematurity (24%) and neonatal sepsis (24%). Malaria was the leading cause of death beyond the neonatal period accounting for 42% of cases. Other common mortality causes were pneumonia, septicaemia, diarrhea, HIV AIDS and meningitis each accounting for 10%, 10%, 7%, 7% and 5% respectively. The months of July, May and March accounted for most deaths (12%, 12% and 11% respectively). CONCLUSION: Birth asphyxia and malaria associated deaths were responsible for most deaths during neonatal and beyond neonatal periods respectively. Presence of trained personal at all deliveries will help to reduce neonatal asphyxia. Efforts should be made to reinforce the existing effective malaria control tools.

Socioeconomic status and obesity in Abia State, South East Nigeria.

BACKGROUND AND OBJECTIVES: Obesity is a major risk factor for cardiovascular disease in developed and emerging economies. There is a paucity of data from Nigeria on the association between socioeconomic status and obesity. The aim of this study is to highlight that association in Abia State, South East Nigeria. MATERIAL AND METHODS: This was a cross-sectional survey in South East Nigeria. Participating subjects were recruited from the three senatorial zones of Abia state. A total of 2,487 adults took part in the study. The subjects were classified based on their monthly income and level of educational attainment (determinants of obesity). Monthly income was classified into three groups: low, middle, and upper income, while educational level was classified into four groups: no formal education, primary, secondary, and tertiary education. Body mass index of subjects was determined and used for defining obesity. Data on blood pressure and other anthropometric measurements were also collected using a questionnaire, modified from the World Health Organization STEPwise Approach to Chronic Disease Risk Factor Surveillance. RESULTS: Overall, the prevalence of obesity in low, middle, and upper income groups was 12.2%, 16%, and 20%, respectively. The overall prevalence of obesity in individuals with no formal education, primary, secondary, and tertiary education was 6.3%, 14.9%, 10.5%, and 17.7%, respectively. Educational status was found to be significantly associated with obesity in women, but not in men, or in the combined group. However, level of income was observed to be significantly associated with obesity in men, women, and in the combined group. CONCLUSION: Sociodemographic and socioeconomic factors are important determinants of obesity in our study population, and therefore may be indirectly linked to the prevalence and the outcomes of cardiovascular disease in Nigeria.

Prevalence of abdominal obesity in Abia State, Nigeria: results of a population-based house-to-house survey.

BACKGROUND AND OBJECTIVE: Abdominal obesity is associated with the risk of developing disorders, such as diabetes and hypertension. The objective of this study was to investigate the prevalence of abdominal obesity in Abia State, Nigeria. MATERIALS AND METHODS: We carried out a cross-sectional study aimed at ascertaining the prevalence of abdominal obesity in Abia State, Nigeria. Participants in the study were recruited from communities in the three senatorial zones in the state. Screening for abdominal obesity was carried out in these subjects using waist circumference (the National Cholesterol Education Program Third Adult Treatment Panel criteria were used). The World Health Organization Stepwise Approach to Surveillance of chronic disease risk factors was used. Body mass index, anthropometric measurements, and other relevant data were also collected. RESULTS: Data on waist circumference were obtained from 2,807 subjects. The prevalence of obesity using body mass index in the population was 11.12%. In men and women, it was 7.73%, and 14.37%, respectively. The prevalence of abdominal obesity in the population was 21.75%. In men and women, it was 3.2% and 39.2%, respectively. CONCLUSION: The prevalence of abdominal obesity is high in Nigeria, and needs to be monitored because it is associated with increased cardiovascular risk.

Prevalence of overweight and obesity in adult Nigerians - a systematic review.

BACKGROUND: Obesity is a major health problem, and there is an increasing trend of overweight and obese individuals in developing countries. Being overweight or obese is known to contribute significantly to morbidity and mortality rates in various countries around the world. We therefore aimed to identify and discuss current epidemiological data on the prevalence of obesity in Nigeria. METHOD: A systematic review of papers published on the prevalence of obesity among adults in the country was carried out. We covered work published in MEDLINE, PubMed, Google, and African Journals Online using the terms "prevalence of overweight and obesity in Nigeria" or "overweight and obesity in Nigeria." In addition, personal inquiries were made. The search limits were articles published from January 2001 to September 2012. Only studies that used the body mass index to assess for overweight and obesity were included. RESULTS: Four studies met the inclusion criteria out of the 75 studies reviewed. In Nigeria, the prevalence of overweight individuals ranged from 20.3%-35.1%, while the prevalence of obesity ranged from 8.1%-22.2%. CONCLUSION: The prevalence of overweight and obese individuals in Nigeria is of epidemic proportions. There is a need to pay closer attention to combating these health disorders.

Proximate Family Biosocial Variables Associated with Severe Malaria Disease among Under-Five Children in Resource-Poor Setting of a Rural Hospital in Eastern Nigeria.

BACKGROUND: Malaria threatens the life of under-five in rural Nigerian families. Although, factors that influence malaria in under-five are manifold. However, family biosocial factors may contribute to the variability of the clinical picture. AIM: To determine proximate family biosocial variable associated with severe malaria among under-five children in a resource-poor setting of a rural hospital in Eastern Nigeria. MATERIALS AND METHODS: A cross-sectional study carried out on the families of under-five managed for malaria. Data extracted included family biosocial variables and diagnosis. An under-five child was defined to have malaria if the mother gave complaints of fever, vomiting, and other symptoms suggestive of malaria, had body temperature exceeding 37.5°C with the asexual forms of Plasmodium falciparum detected on the peripheral blood film. Severe malaria is the malaria that presents with life-threatening features like severe anemia and cerebral malaria. RESULTS: The prevalence of severe malaria was 31.8% The family biosocial variables significantly associated with severe malaria were maternal low level of education (P = 0.031), family size >4 (P = 0.044), low social class of the family (P = 0.025), nonliving together of parents (P = 0.011), and poor access to health facilities (P = 0.038). The most significant predictor of severe malaria was nonliving together of parents (P = 0.000, odds ratio = 3.08, confidence interval = 1.64-5.10). CONCLUSION: This study has demonstrated that some family biosocial variables are associated with severe malaria. These families should constitute at risk families that could be targeted for malaria interventional programs.
