RESUMO
BACKGROUND: Tobacco use is associated with medical, social and economic problems. There is paucity of data on tobacco use among undergraduates in northern Nigeria. This study assessed pattern and predictors of tobacco use among undergraduates in Zaria, North-western Nigeria. METHOD: It was a cross-sectional study of undergraduates in three tertiary institutions. Multi-stage sampling technique was used to select 1,080 undergraduates. Data was collected using a questionnaire adapted from Global Adult Tobacco Survey and Global Youth Tobacco Survey. Bi-variate analysis was used to identify independent variables showing statistically significant association with current tobacco use. These were entered into step-wise logistic regression. RESULTS: Their median age was 24 years (range:15-47). Prevalence of current tobacco use was 27.0%. About 58.7% smoked tobacco daily and 40.0% used smokeless tobacco daily. Commonest places where tobacco was used were off campus accommodation (30.2%), social center (30.2%) and bar or club (28.1%). Predictors of tobacco use were being a male [2.64(1.82-3.84)], married [2.33(1.49-3.70)], experiencing tobacco promotional activity [1.56(1.12-2.17)], willing to use promotional objects [2.06(1.35-3.14)], using of promotional objects [2.74(1.90-3.96)], and exposure to secondhand smoke [14.10(4.16-47.81)]. Predictors of non-use of tobacco were spending two years or less awaiting university admission [0.65 (0.46-0.91)], parents currently together [0.48(0.33-0.69)], and supporting ban on tobacco [0.34 (0.23-0.48)]. CONCLUSION: Prevalence of tobacco use and expenditure on tobacco were high. University authorities should commence programs to identify tobacco users and encourage cessation. The findings also highlight the need to establish effective tobacco surveillance system that includes students of tertiary institutions.

CONTEXT: Neonatal sepsis is an important cause of morbidity and mortality of newborns, especially in developing countries. AIMS: Our study determined the prevalence of neonatal sepsis and its predisposing factors among neonates admitted in Ahmadu Bello University Teaching Hospital (ABUTH). SETTINGS AND DESIGN: This was a cross-sectional descriptive study conducted in ABUTH. SUBJECTS AND METHODS: The data were abstracted from the case notes of neonates admitted from May 2017 to May 2018. A pretested pro forma was used to abstract the data. STATISTICAL ANALYSIS USED: Odds ratios and multivariate logistic regression were used to determine the factors associated with neonatal sepsis among the study population. RESULTS: The prevalence of neonatal sepsis was 37.6%. Escherichia coli was the most commonly isolated organism. Neonates 0-7 days of age were 2.8 times less likely to develop neonatal sepsis than older neonates. Babies born with an Apgar score of <6 within the 1st min were 2.4 times more likely to develop neonatal sepsis than those whose Apgar score was higher. Neonates of mothers who had urinary tract infection during pregnancy were 2.3 times more likely to have had sepsis and those whose mothers had premature rupture of membranes were 4.6 times more likely. CONCLUSIONS: The prevalence of neonatal sepsis was high among the neonates studied. Neonatal and maternal factors were associated with sepsis in the neonates. These findings provide guidelines for the selection of empirical antimicrobial agents in the study site and suggest that a continued periodic evaluation is needed to anticipate the development of neonatal sepsis among neonates admitted.
RESUMO
INTRODUCTION: Indoor residual spraying (IRS) is among the major vector control strategies recommended for endemic populations by the World Health Organization (WHO). The success of IRS requires high coverage which is dependent on its acceptability. In Nigeria, IRS pilots have been ongoing and rejection has been a major setback to its coverage. We assessed coverage of IRS and determined factors associated with its acceptability in Nasarawa Eggon district, Nasarawa state, Nigeria. METHODS: A cross-sectional survey involving 409 households selected using multi-stage sampling was carried out. Trained data collectors administered pre-tested structured questionnaire to collect data on socio-demographic characteristics of household heads or their representatives, their perceptions on IRS and factors associated with IRS acceptability. Descriptive, bivariate and multivariate analyses were done at 5% level of significance. RESULTS: Majority of respondents were male (79.7%) and married (82.6%), and their mean age was 36.4 ± 13.3 years. Coverage of IRS was 99.3%. However, only 82.6% of those who previously accepted IRS were willing to accept it in again. Factors independently associated with acceptability were perceived effectiveness of IRS (aOR = 21.8; 95%CI = 6.9-68.8) and lower household cost of malaria prevention after IRS (aOR = 5.0; 95%CI = 1.1-21.8). CONCLUSION: IRS coverage in the communities studied met WHO minimum standard of 85%. However, for similar results to be achieved in future, acceptability must be promoted by providing information on its effectiveness and its ability to reduce household cost of malaria prevention.

INTRODUCTION: Dyslipidemia confers excess atherosclerotic cardiovascular risk in type 2 diabetes mellitus (DM) patients, and this requires prompt identification and management to reduce morbidity and mortality. This study assessed the prevalence and pattern of dyslipidemia in type 2 DM patients in Zaria, Northwestern Nigeria. METHODS: This was a cross-sectional study of newly diagnosed type 2 DM patients at Ahmadu Bello University Teaching Hospital (ABUTH), Zaria. Demographic, clinical and laboratory data were extracted from the case notes of eligible patients and analyzed using STATA version 14. Continuous variables were presented as mean ± standard deviation (SD), or median and interquartile range (IQR) while categorical variables were as frequencies and percentages. Student t and chi-square tests were used to test for association at p < 0.05. RESULTS: A total of 322 subjects (161 male, 161 female) with a mean age of 53.5 ± 10.8 years partook in the study. The prevalence of dyslipidemia was 69.3%. Mixed dyslipidemia of high triglyceride (TG) and high low-density lipoprotein cholesterol (LDL-C) was present in 41.0%; high TG and low high-density lipoprotein cholesterol (HDL-C) in 2.8%; and high LDL and low HDL in 2.5%. Atherogenic dyslipidemia, isolated hypercholesterolemia and isolated low HDL-cholesterol were present in 3.4%, 2.5% and 23.6% respectively. Dyslipidemia status was not associated with age, sex, duration of DM or hypertension, obesity, and mean fasting blood sugar (FBS) and 2-hour postprandial glucose. CONCLUSION: The prevalence of dyslipidemia is high in the newly diagnosed type 2 DM patients and therefore, initial management should incorporate measures to control dyslipidemia.

INTRODUCTION: in 2015, 212 million malaria cases and 429,000 malaria deaths were estimated globally. Kaduna State, located in northern Nigeria had a malaria prevalence rate of 36.7% among children less than 5 years old which was higher than the national average of 27%. We assessed the trend of malaria cases in Kaduna State from 2011 to 2015, to analyse trend of malaria in Kaduna as well as describe malaria in time, place and person. METHODS: we conducted secondary data analysis of Kaduna State malaria data between January 2011 and December 2015. Data were extracted from the Integrated Disease Surveillance and Response (IDSR) 003 form. Data of uncomplicated malaria defined as "any person with fever or history of fever within 24 hours; without signs of severe disease (vital organ dysfunction)" was analysed. In IDSR, a case of malaria is based on presumed diagnosis. Frequencies and proportions were calculated. We also conducted trend analysis of incidence of malaria. RESULTS: in the period under study, 1,031,603 malaria cases were recorded with 238 deaths (CFR = 0.23 per 1,000). There was a downward trend with a slope of -3287.2. The data showed higher seasonal variation for quarters 2 (1430.96) and 3 (Q2 = 6,460.23) compared to Quarters 1 (6,857.19) and 4 (-1,034.01). Overall, the age group 12 -59 months had the highest number of incident cases 225, 537 (20.3%). Malaria death was highest in children 1 to 11 months (26.5%) and least, in children 0 -28 days (2.5%). CFR was also highest in children 1 to 11 months (0.45 per 1,000). The highest incidence of malaria cases was in Jaba Local Government Area (47.7%) and the least, in Lere (2.4%). CONCLUSION: there was a decreased incidence of malaria from 2011 to 2015. Malaria was most common in the second and third quarters of each year. Age group 12-59 months was most affected. Kaduna State Malaria Programme should sustain the programs it is implementing and focus more on the under-five years age group.

INTRODUCTION: Malaria is the commonest cause of morbidity and mortality among displaced populations especially children in endemic countries. Nigeria, an endemic country, has had increase in internally displaced persons (IDP) due to insurgency. utilization of long-lasting insecticidal nets (LLIN) is a key strategy employed to achieve global targets of malaria elimination and its effectiveness is determined by utilization, coverage and maintenance. We determined the coverage and utilization of LLIN among children aged 6-59 months at IDP camps and its predictors. METHODS: A cross-sectional study was conducted among children aged 6-59 months at the three IDP camps in Abuja. We collected data on socio-demographic characteristics, LLIN ownership and utilization using computer-aided interview, complemented by direct observation of nets. We defined universal LLIN coverage as the proportion of households with one LLIN to two persons and utilization as an eligible child sleeping under the LLIN the night preceeding the survey. Bivariate analysis was done at p < 0.25 and logistic regression at 5% level of significance. RESULTS: Overall, 393 children were enrolled with mean age of 33.3 ± 17.4 months, 51.6% were female. Household LLIN ownership was 76.7.5%, universal coverage 11.2% and utilization 89.7%. Independent predictors of LLIN utilization were LLIN hung at sleeping area (adjusted OR: 99.9, CI: 22.7 - 438.8) and type of camp site (adjusted OR: 8.2, CI: 2.5 - 27.4). CONCLUSION: LLIN utilization was high in these IDP camps despite low coverage. LLIN distribution and hanging campaigns are recommended to reduce malaria transmission in the IDP camps.

INTRODUCTION: Contrary to World Health Organizations recommendations, health workers (HWs) still prescribe antimalarials to malaria rapid diagnostic test (mRDT)-negative patients, thus increasing overuse and the risk of parasite resistance to the antimalarials. The reasons for this are not clear. We identified factors associated with antimalarial prescription to mRDT-negative patients. METHODS: We conducted a cross-sectional study among 423 HWs. Data on socio-demographic characteristics, training, supervision experience and fever management practices were collected. We tested associations between independent variables and prescription of antimalarials to mRDT-negative patients using Chi square and logistic regression at p < 0.05. RESULTS: The HWs were mostly community health workers (58.6%), with mean age of 41.0 (±8.8) years and 13.6 (± 9.0) years of professional practice. Females were 322 (76.1%) and 368 (87%) were married. Of the 423 HWs interviewed, 329 (77.8%) received training on mRDT use, 329 (80.6%) received supervision and 129 (30.5%) had good knowledge of causes of fever. Overall, 110 (26.0%) of the HWs prescribed antimalarials to mRDT-negative patients. A higher proportion of non-trained vs trained HWs [Adjusted Odds Ratio (aOR) = 4.9; 95% Confidence Interval (CI) (2.5-8.3)], and HWs having poor knowledge vs HWs having good knowledge of causes of fever [aOR = 1.9; 95% CI (1.0-3.5)], prescribed antimalarials to mRDT-negative patients. CONCLUSION: HWs' lack of training on mRDT use and poor knowledge of causes of fever were associated with prescription of antimalarials to mRDT-negative patients. We recommend training on management of fever and mRDT use to reduce such inappropriate antimalarial prescriptions.

INTRODUCTION: Worldwide, hypertension and diabetes mellitus (DM) are major causes of morbidity and mortality. This study assesses the prevalence and correlates of hypertension and DM in an urban community in northwestern Nigeria. METHODS: This was a cross-sectional descriptive study. Adults aged 18 years and above, who attended a medical outreach program were interviewed and screened for hypertension and DM. Anthropometry, blood glucose and blood pressure were measured with standard instruments and methodology. Primary outcomes were hypertension and DM. Data were analyzed using STATA version 14 and presented as mean ± standard deviation and frequencies. Chi-square and Pearson's correlation co-efficient were used to identify the correlates of hypertension and DM, at 5% level of significance. RESULTS: The mean age of participants was 51.0 ± 14.0 years and 87.8% were females. Prevalence of hypertension and DM were 55.9% and 23.3% respectively. Age greater than 40 years and female gender were associated with risk of hypertension and DM respectively, p < 0.05. There was a weak correlation between systolic hypertension and age (r = 0.18, p = 0.02), diastolic hypertension and body mass index (r = 0.16, p = 0.03) and blood sugar and waist circumference (r = 0.19, p = 0.02). CONCLUSION: The high prevalence of hypertension and DM among the study population highlights the need for the development and implementation of a community-based public health interventions aimed at reducing their risk factors.

The use of control group in clinical trials has been universally acclaimed by researchers to effectively help discriminate between the actual effects of an intervention and those arising from other factors. However, the choice of the control that provided both scientific and ethical acceptability among researchers has been a source of intense debate. We conducted a literature search on the use of placebo and active controls in clinical trials and X-ray the arguments for and against both choices in randomized control trials and concluded by highlighting the scenarios where the use of placebo is justified.

BACKGROUND: Low level of utilisation of maternal health services is a major factor responsible for high maternal mortality in northwestern region of Nigeria. This study was aimed at determining the barriers to utilisation of maternal health services from the perspective of mothers in northwestern Nigeria. MATERIALS AND METHODS: A cross-sectional study of 150 mothers, selected through multistage technique, was conducted. Data were collected using a structured interviewer-administered questionnaire, and analysed using SPSS statistics 17.0. RESULTS: Only 2.7% utilised preconception service, 98.7% antenatal care service (ANC), 24.0% delivery, 35.3% postnatal care and 14.0% utilised family planning service. Major reasons for non-utilisation of delivery service were not having a delivery complication in the past (57% (CI = 47.4-66.1)) and negative provider attitude (23.7% (CI = 16.4-32.7)). For non-utilisation of postnatal care, the major reasons were also not having a postnatal complication in the past (60.8% (CI = 50.4-70.4)) and negative provider attitude (27.8% (CI = 19.4-38.0)). As for non-utilisation of family planning service, the major reason was desire to have more children (32.6% (CI = 24.7-41.4)). Reasons for non-use of preconception care and ANC were not computed because respondents to these questions were not enough; only 6 (4.0%) were aware of preconception care in the first place and only 2 (1.3%) were not using ANC. CONCLUSION: Despite living near a health facility, most of the mothers were not using maternal health services. It is recommended that while there is the need to raise awareness on the utilisation of maternal health services, bring it closer to the mothers and make it more affordable, there is a more pressing need to improve its quality, especially through the alleviation of negative attitude of health care providers.
