Co-occurrence of non-communicable disease risk factors among adolescents in Jos, Nigeria.

BACKGROUND: The co-occurrence and clustering of risk factors for non-communicable disease (NCD) is a global public health concern. AIM: This study aimed to assess the co-occurrence and clustering of risk factors for NCDs among in-school and out-of-school adolescents in Jos North Local Government Area, Plateau State, Nigeria. SETTING: Secondary schools and markets in Jos North Local Government Area. METHODS: A comparative cross-sectional study was conducted among 377 in-school and 377 out-of-school adolescents, aged 10-19 years of age. An interviewer-administered questionnaire was used to collect information on behavioural and physical risk factors for NCDs. Chi-square and Mann-Whitney U tests were used for comparisons at a 5% level of significance. Statistical analysis was carried out using Statistical Product and Service Solutions (SPSS) version 23.0. RESULTS: Of the 754 sampled adolescents, 386 (51.2%) were females and 368 (48.8%) were males. Adolescents aged 10-14 years made up 37.8% of the participants, 15 to 17 years of age accounted for 46.9% and 18-19 years 15.3%. Risk factors with the highest prevalence were a sedentary lifestyle (94.2%) and an unhealthy diet (92.4%). Majority (97.2%) had two or more risk factors while 1.9% of adolescents had no risk factor. More in-school adolescents (24.1%) had two risk factors compared to 14.1% of out-of-school adolescents (p 0.001); 14.1% of out-of-school adolescents had five or more risk factors compared to 2.9% of those in school (p 0.001). CONCLUSION: Co-occurrence and clustering of behavioural and physical risk factors was found among both in-school and out-of-school adolescents.Contribution: This study highlighted the burden of risk factors for NCDs among both in-school and out-of-school adolescents in the North-Central part of Nigeria. This is especially useful in developing targeted interventions to tackle these risk factors.

Prevalence of hepatitis B virus infection in pregnant women with and without HIV in Jos, Nigeria.

OBJECTIVE: To compare the prevalence of hepatitis B virus (HBV) in pregnant women with and without human immunodeficiency virus (HIV) in Jos, Nigeria. METHODS: This comparative cross-sectional study of pregnant women was undertaken between 1 November 2017 and 30 April 2018. Informed consent was obtained, demographic data and predictors for HBV were collected, and all women were screened for HIV and HBV. Descriptive statistics and multivariate analyses using STATA Version 15 were performed. RESULTS: Of 3238 women enrolled, 12.6% and 7.2% of those with and without HIV had HBV, respectively (P = 0.01). Women with HIV, higher parity [adjusted odds ratio (aOR) 0.68, P < 0.01], lower gestational age (aOR 1.04, P < 0.01) and without prior HBV vaccination (aOR 0.40, P < 0.01) were significantly more likely to have HBV infection. CONCLUSIONS: Among pregnant women, the prevalence of HBV was higher among those with HIV. Predictors of HBV included being multigravida or grand-multigravida, registration for antenatal care before 20 weeks of gestation, and no prior HBV vaccination. In settings with endemic HBV and HIV, integration of effective HBV and HIV prevention services could greatly decrease the transmission and prevalence of HBV.

Cardiovascular Anthropometry: What Is Best Suited for Large-Scale Population Screening in Sub-Saharan Africa?

Background : Body mass index (BMI) measures overweight/obesity. It, however, especially in sub-Saharan Africa (SSA), misclassifies cardiometabolic risk. Central obesity measures are superior. We therefore sought to compare BMI, waist-to-hip ratio (WHR) and abdominal height (AH) in predicting cardiovascular disease risk in sub-Saharan Africa. Methods : Subjects had blood pressures, BMI, and WHR determined. Blood pressure was taken, weight and height measured to generate BMI, and AH measured with a new locally fabricated abdominometer. The ability of the anthropometric indices in identifying abnormal individuals needing intervention was assessed with sensitivity, specificity, and area under the receiver operator characteristic curve. Results : Adults totaling 1,508 (728 M/780 F) adults were studied. For BMI, 985 (65.3%) were normal, while 375 (24.9%), consisting of 233 males and 142 females, had normal WHR. Blood pressure was normal in 525 (34.8%) and 317 (21.0%) for systolic and diastolic blood pressures, respectively. Using BMI as gold standard, sensitivity, specificity, positive, and negative predictive values for WHR in males were 80.7, 37.5, 62.5, and 19.3%, respectively. For females and in the same order, they were 62.0, 34.3, 65.7, and 38.0%. For AH, it was equal in both genders at 82.6, 39.2, 60.8, and 17.4%. By receiver operating curves comparing AH, WHR, and BMI against blood pressure detection, the area under the curve was 0.745, 0.604, and 0.554 for AH, BMI, and WHR, respectively. Conclusion : Abdominometer-derived AH has a better sensitivity and greater area under the receiver operator curve compared with BMI and WHR in this sub-Sahara African population; implying superiority as a cardiovascular anthropometric index.

Profile of congenital heart disease in infants born following exposure to preeclampsia.

BACKGROUND: Events in pregnancy play an important role in predisposing the newborn to the risk of developing CHD. This study evaluated the association between maternal preeclampsia and her offspring risk of CHD. METHODS: This is a cohort study of 90 sex-matched neonates (45 each born to women with preeclampsia and normal pregnancy) in Jos, Nigeria. Anthropometry was taken shortly after delivery using standard protocols. Echocardiography was performed within 24 hours of life and repeated 7 and 28 days later. SPSS version 25 was used in all analyses. Statistical significance was set at p<0.05. RESULTS: Congenital heart disease (CHD) was observed in 27 (30.0%) of newborns of women with preeclampsia compared with 11 (12.1%) of newborns without preeclampsia (p<0.001) at the end of 7 days and in 19 (21.1%) of newborns of women with preeclampsia and 3 (3.3%) of newborns of women without preeclampsia by the end of the 4th week of life (p<0.001). Overall, ASD (4 newborns), PDA (21 newborns), patent foramen ovale (14 newborns) and VSD (2 newborns) were the prevalent lesions found among all the newborns studied in the first week of life. Isolated atrial and ventricular septal defects were seen in 4 (4.4%) of the newborns of women with preeclampsia. Being the infant of a woman with preeclampsia was associated with about 8-fold increased risk of having CHD (OR = 7.9, 95% CI = 2.5-24.9, p<0.001). CONCLUSION: CHD may be more common in newborns of women with preeclampsia underscoring the need for fetal and newborn screening for CHD in women with preeclampsia so as to improve their infant's well being.

Effectiveness and Safety of Hydroxyurea in the Treatment of Sickle Cell Anaemia Children in Jos, North Central Nigeria.

BACKGROUND: Hydroxyurea has been shown to positively modify sickle cell disease pathogenesis, but its use is low among Nigerian sickle cell anaemia (SCA) patients because of effectiveness and safety concerns. METHODS: We conducted a quasi-experimental study to evaluate the effectiveness and safety of hydroxyurea in 54 SCA children aged 4-17 years. Clinical and haematological parameters were compared at baseline and 12 months after hydroxyurea therapy. The participants were monitored for adverse events. The parameters were compared using relative risk and Wilcoxon Signed-Rank Test. RESULTS: The number of subjects who had more than two episodes of painful crises reduced from 27 (50%) to 2 (2.7%) (p < 0.001), while those who had acute chest syndrome reduced from 6 (11.1%) to 0 (0.0%; p < 0.001). The risk of being transfused more than once was 0.11 times the risk in the 12 months period preceding therapy (95% CI = 0.02-0.85; p = 0.016). Similarly, the risk of hospital stay >7 days was 0.08 times the risk at the baseline (95% CI = 0.02-0.24; p < 0.0001). The median haematocrit and percentage foetal haemoglobin increased from 26 to 28% and 7.8 to 14%, respectively (p < 0.0001). A dose-dependent but reversible leucopenia was observed among six children (11.1%), otherwise, hydroxyurea was safe in the study population. CONCLUSION: Hydroxyurea is effective and safe in SCA children in Jos, Nigeria. The findings could strengthen educational programme aimed at improving the utilization of hydroxyurea among SCA children.

Treatment compliance and retention in care among out-patient clients in a tertiary health institution in plateau state North Central Nigeria.

BACKGROUND: Compliance with prescribed treatment and retention in care are key components in the management of chronic diseases which is vital in averting the long term complications that could arise from such conditions. Failure to comply with treatment recommendations is often associated with poor retention in care. In view of this, this study was conducted to determine the level of treatment compliance and retention in care among patients with hypertension and diabetes in Jos University Teaching Hospital. METHODS: This was a cross sectional study conducted among 290 eligible respondents between September and November 2017 using quantitative method of data collection. SPSS version 20 was used for data analysis with adjusted odds ratio and 95% confidence interval used as point and interval estimates while p-value of ≤0.05 was considered statistically significant. RESULTS: The mean age of the respondents was 54.5±13.1 years with 43.8% of the respondents found to have satisfactorily complied with prescribed treatment while 117 (40.3%) were uninterruptedly retained in care within the last 6 months' clinic appointments prior to the study. CONCLUSIONS: This study has demonstrated the levels of compliance with treatment and retention in care bringing to bear the need to provide structured interventions targeted at attaining improvement in compliance with treatment and retention in care among individuals on long term care.

Estimation of weight in adults from height: a novel option for a quick bedside technique.

PURPOSE: In critical care situations, there are often neither the means nor the time to weigh each patient before administering strict weight-based drugs/procedures. A convenient, quick and accurate method is a priority in such circumstances for safety and effectiveness in emergent interventions as none exists in adults while those available are complex and yet to be validated. We aimed to study the correlation and accuracy of a quick bedside method of weight estimation in adults using height. METHOD: The technique is estimated body weight-eBW(kg) = (N - 1)100, where 'N' is the measured height in metres. Adult undergraduates were enrolled 10/09/2015. Their heights and weights were measured while the formula was used to obtain the estimated weight. The SPSS version 21.0, Chicago, IL, USA was utilised for data analysis. RESULTS: We analysed 122 participants aged 21-38 years with height = 1.55 m-1.95 m. The actual body weight range = 48.0 kg-91.0 kg, mean = 65.3 kg ± 9.7 kg and S.E. = 2.0 while eBW = 55 kg-95 kg, mean = 69.1 kg ± 8.4 kg and S.E. = 1.5. On BMI classes, a positive predictive value of 94.7% for the 'normal' category and 95.5% for 'overweight'. Correlation coefficient at 99% confidence interval yielded (r) = + 1, (P = 0.000) while the linear regression coefficient (r2) = + 1 at 95% confidence interval (P = 0.000). The strength of agreement/precision was established by the Bland-Altman plot at 95% ± 2 s (P = 0.000) and kappa statistic with value = 0. 618. CONCLUSION: This unprecedented statistical characterisation of the two weight estimate measures to have a good agreement scientifically proposes the utility of our method with the formula eBW(kg) = 100(N-1) in critical care and ATLS protocol.

Training: A vital tool for improving the knowledge and practice of food safety and hygiene among food handlers in boarding secondary schools in Plateau State.

BACKGROUND: Food is an important basic necessity, its procurement, preparation and consumption are vital for the sustenance of life. Food handlers have been found to play prominent roles in the transmission of food borne diseases, therefore training of food handlers on food safety and hygiene is crucial to the prevention of food borne diseases. METHODOLOGY: A quasi-experimental study carried out among food handlers in boarding secondary schools in Jos North Local Government Area to determine the effect of training on the knowledge and practice of food safety and hygiene. EPI info statistical software version 3.5.4 was used for data analysis and 95% confidence interval was used in this study with a P ≥ 0.05 considered statistically significant. RESULT: The mean age of the food handlers in the study was 42.07 ± 8.71 years with the mean years of work experience as 11.59 ± 8.05 years. The level of knowledge of food safety and hygiene improved significantly after the training (P < 0.001). Majority (98.5%) of the food handlers had good practice of food safety and hygiene after the training as against 51.5% who had same before the training (χ2 = 76.6; P < 0.001). CONCLUSION: This study has demonstrated the effectiveness of training in improving the knowledge and practice of food safety and hygiene among food handlers.

Effect of health education on the uptake of HIV counseling and testing among long distance drivers in Jos North Local Government Areas of Plateau State.

BACKGROUND: The impact of HIV/AIDS has been felt in virtually all aspects of life. Long distance drivers are of particular concern to HIV prevention and care programs because they constitute a high risk group. HIV Counseling and Testing (HCT) is an intervention, which gives the client an opportunity to confidentially discuss his or her HIV risks and be assisted to learn his/her HIV status for purposes of prevention, treatment, care and support. The objective of this study was to determine the effect of health education on the uptake of HCT among Long Distance Drivers (LDDs) in Plateau State. METHODOLOGY: This was a quasi-experimental study with a pre and post intervention phase carried out among 161 LDDs in Jos North Local Government Areas. Health education intervention was provided using a structured health education guide in the form of lecture and discussion. Epi-info™ statistical software version 3.5.4 developed by Centre for Disease and Control and Prevention (CDC) 1600 Clifton Rd. Atlanta, GA 30333 usa was used for data analysis and 95% confidence interval was used for the study and P ≤ 0.05 was considered as statistically significant. RESULTS: The mean age of the respondent in this study was 41.0 ± 7.9 years with majority (92.5%) of the LDDs married and 91.3% resident within the state. Knowledge and uptake of HCT among LDDs improved significantly from 4.17 ± 1.43 to 6.70 ± 1.55 and 18.6-57.2% following the intervention (P < 0.001) respectively. CONCLUSION: This study has shown that health education is an effective tool in improving the uptake of HCT among long distance drivers. Therefore, it should be used to improve HCT uptake among high risk groups.

Supportive supervision: an effective intervention in achieving high quality malaria case management at primary health care level in Jos, Nigeria.

BACKGROUND: Supportive supervision is a form of supervision that promotes quality at all levels of health system by strengthening relationships within the system through prompt identification and resolution of problems among others. It is an effective intervention in improving health worker performance in low resource settings. Malaria is responsible for majority of outpatient consultations in Nigeria at all levels of care. MATERIALS AND METHODS: This was a facility-based interventional study with pre and post-intervention phases conducted among two groups.The study subjects were selected through a multistage sampling technique and data collection was done using both semistructured interviewer administered questionnaire and supervisory checklist. RESULTS: The mean knowledge scores of malaria within the intervention group showed an increase from 10.3 ± 1.4 at preintervention to 11.3 ± 1.5 at post-intervention (P < 0.0015). The proportion of respondents who correctly followed malaria management guidelines increased from 32.73% at first supervisory visit to 70.91% by the third supervisory visit (P < 0.001). An analysis of the supervisory checklist showed improvement in performance of healthcare workers with each supportive supervisory visit in most of the variables examined. CONCLUSIONS: This study has demonstrated that supportive supervision is a feasible and practicable tool in improving knowledge and practice of malaria case management among PHC workers.

Prevention of nutritional rickets in Nigerian children with dietary calcium supplementation.

Nutritional rickets in Nigerian children usually results from dietary calcium insufficiency. Typical dietary calcium intakes in African children are about 200mg daily (approximately 20-28% of US RDAs for age). We sought to determine if rickets could be prevented with supplemental calcium or with an indigenous food rich in calcium. We enrolled Nigerian children aged 12 to 18months from three urban communities. Two communities were assigned calcium, either as calcium carbonate (400mg) or ground fish (529±109mg) daily, while children in all three communities received vitamin A (2500IU) daily as placebo. Serum markers of mineral homeostasis and forearm bone density (pDEXA) were measured and radiographs were obtained at enrollment and after 18months of supplementation. The overall prevalence of radiographic rickets at baseline was 1.2% and of vitamin D deficiency [serum 25(OH)D<12ng/ml] 5.4%. Of 647 children enrolled, 390 completed the 18-month follow-up. Rickets developed in 1, 1, and 2 children assigned to the calcium tablet, ground fish, and control groups, respectively (approximate incidence 6.4/1000 children/year between 1 and 3years of age). Children who developed rickets in the calcium-supplemented groups had less than 50% adherence. Compared with the group that received no calcium supplementation, the groups that received calcium had a greater increase in areal bone density of the distal and proximal 1/3 radius and ulna over time (P<0.04). We conclude that calcium supplementation increased areal bone density at the radius and ulna, but a larger sample size would be required to determine its effect on the incidence of rickets.

Perceptions of working conditions amongst health workers in state-owned facilities in northeastern Nigeria.

BACKGROUND: The health care sector depends to a large extent on human labor. Poor worker motivation can greatly affect health outcomes and patient safety. There is little information on the health workers' perceptions of working conditions in resource-poor settings. METHOD: Three state-owned facilities in each state were selected by simple random sampling technique. The selected facilities were visited on weekdays between 9 and 10 a.m. A self-administered structured questionnaire was given to all health care workers on duty in the facility at the time of visit. RESULTS: A total of 299 questionnaires were returned. The response rate was 85.43%. Two hundred four (68.2%) workers experienced general satisfaction with their current jobs. The relationships between general job satisfaction and presence of conflict at work (P = 0.001), freedom of expression (P > 0.001), managerial support for staff welfare (P > 0.001), managerial support for staff career development (P > 0.001), availability of tools and consumables in the workplace (P > 0.001) and progress towards personal professional goals (P = 0.001) were statistically significant. CONCLUSION: The level of general job satisfaction was high. Though salaries were important, presence of conflict at work, freedom of expression, managerial support for staff welfare, managerial support for staff career development, availability of tools and consumables in the workplace and progress towards personal professional goals appear to play a role in worker motivation.

Risk factors associated with dental fluorosis in Central Plateau State, Nigeria.

OBJECTIVES: Dental fluorosis is known to occur in some parts of Plateau State, but the factors responsible for its occurrence are unknown. The purpose of this study, therefore, was to determine the factors associated with the occurrence of dental fluorosis in Central Plateau. METHODS: The study was cross-sectional and comparative in design. Subjects were selected using the multi-stage sampling technique. One Local Government Area each was randomly selected from the high and low altitude parts of the district, and from each selected Local Government Area two health districts were randomly selected with probability proportional to size. From each of the selected health districts two major settlements were selected again with probability proportional to size. Twelve- to fifteen-year-old lifelong residents of the selected settlements were then selected for study. Each respondent completed an interviewer-administered questionnaire after which he/she was clinically examined to ascertain his/her fluorosis status. Samples of water were collected from water sources consumed by the respondents in each settlement. RESULTS: One thousand one hundred children aged 12-15 years were studied, 554 (50.4%) of which lived in the high altitude part of the district and 546 (49.6%) in the low altitude part of the district. Fluorosis prevalence was significantly associated with altitude and the fluoride level of water. The prevalence of fluorosis was significantly associated with altitude (chi(2) = 85.735, d.f. = 1, P < 0.0001) and the fluoride level of water (chi(2) for trend = 8.009, d.f. = 1, P < 0.05) in the low altitude parts of the district. None of the respondents had used fluoride-containing toothpaste before 4 years of age and none used fluoride supplements. CONCLUSION: The occurrence of dental fluorosis in Central Plateau could be because of the high altitude of the area and the fluoride concentration of the waters consumed in the district.
