An Inquiry into Sexual Health Knowledge and Sexual Risks Among Students of Tertiary Institutions in Ibadan, Southwest Nigeria

Sexual activity is rampant among female undergraduates with the consequence of unintended pregnancies, abortions and sexually transmitted infections. This study was conducted to assess the prevalence and predictors of unprotected sexual intercourse and abortion; the knowledge, access to and use of contraceptives; as well as the knowledge of and exposure to Sexually Transmitted Infections among undergraduates of the Polytechnic and University of Ibadan. It was a descriptive cross-sectional study that employed a multi-stage sampling method. A structured questionnaire was administered to undergraduates of the Polytechnic of Ibadan (PTI) and the University of Ibadan (UI). Data were collected on demographic profile; reproductive and sexual history; knowledge, attitude to and use of contraceptives; and knowledge of and exposure to Sexually Transmitted Infections. Analysis was done using SPSS version 15.0. Significantly more males than females (27% vs 18%) were sexually active and more (25%) students of PTI than UI (19%). Abortion was significantly more prevalent in the Polytechnic (5.3%) than the University (1.6%). The major reason pregnancies were aborted was that they were unplanned for and abortion seekers were not ready for consequent financial responsibilities (57%) of keeping the pregnancies. Knowledge of the various forms of contraception was poor. Males had better access to contraceptives than females and significantly more males (36%) than females (6%) used contraceptives always. Overall, self-pleasure was the single principal reason (75.4%) respondents had for sexual intercourse and significantly more females (21.6%) than males (12.5%) had sex to please their partner(s). Knowledge about sexually transmitted Infections was assessed as fair

Lifestyle Habits and Cardiovascular Risk Factors Among Nurses at The University College Hospital, Ibadan, Southwest Nigeria

This study set out to identify the unhealthy lifestyle habits adopted by nurses at the University College Hospital (UCH), Ibadan which could predispose to Cardiovascular diseases (CVDs) and assess the cardiovascular risk factors among them. A cross sectional study design was utilized. The study population consisted of nurses working on the wards at the UCH, Ibadan who were between the ages of 30-60 years. Systematic random sampling was adopted in selecting 196 nurses for this study. A structured questionnaire was administered to consenting nurses. Focus group discussions were conducted to further probe into the details of the questionnaire. 94.9% of respondents were female and the mean age of respondents was 39.3±7.4 years. About 32% of the respondents engaged in moderate exercise less than once a week, 59% of the respondents slept between 5-6 hours at night, 44.9% ate fried food 1-2 times weekly, 42.9% consumed one or more litres of soda drink per week. Majority demonstrated high level of awareness about cardiovascular risk factors such as cigarette smoking (78.1%), alcohol use (76.5%), overweight/obese (75.5%), high blood cholesterol (73.5%), physical inactivity (71.9%) and diabetes mellitus (70.9%). However, there was a low level of awareness about cardiovascular risk factors such as race (41.3%) and gender (34.2%). A significantly higher proportion (70%) of respondents who ate fried foods on an average of 3-6 times per week were overweight/obese (p=0.016). Obesity was also associated with family history of cardiovascular diseases (p=0.04). The focus group discussions highlighted nurses’ views about difficulties in practicing known healthy lifestyle habits. The study highlighted a moderate prevalence of cardiovascular risk factors such as obesity, consumption of fried foods and physical inactivity among nurses. Efforts should be directed towards the promotion of healthy lifestyles among nurse

Relationship of age, anthropometry and haemoglobin concentration with echocardiographic findings in Nigerian children with sickle cell anaemia

Background: Assessment of the structural and functional effects of sickle cell anaemia (SCA) on the heart can be done using echocardiography.There has been no agreement on which indicator of body size (weight, height, and body surface area (BSA)) or age in children should be used to relate to and correct echocardiographic measurements.Aim: To correlate the echocardiographic findings of children with SCA aged one to fifteen years in steady state with their age, anthropometryand haemoglobin concentration.Methods: A prospective study carried out at the Lagos University Teaching Hospital (LUTH), between May and October 2005. The subjects were 60 paediatric patients attending the LUTH SCA outpatient clinic and 60 age, sex and socioeconomic matched controls. Their height, weight, and echocardiographic parameters were measured and their BSA and haemoglobin level were determined.Results: The direct echocardiographic measurement (AO, LA, LVPW, EDD, ESD, IVS) and LVM each increased progressively with body weight, height, body surface area and age in both subjects and controls (r > 0.3, p < 0.001 in each case). Multivariate analysis showed that height correlated significantly with AO, ESD, EDD and LVPW in the subjects. All the parameters except age were significantly correlated with LVM both in univariate and multivariate analysis.Conclusion: Echocardiographic parameters in SCA patients are significantlycorrelated with anthropometric indices and age. Our data suggest best correlation with height in these subjects

Hepatitis B immunization at the University College Hospital, Ibadan: an eight year review of vaccine administration records

Vaccination of health care workers (HCWs) against hepatitis (HBV) infection is highly necessary in Nigeria where the infection occurs in hperendemic proportions. We hereby determine the trends in the administration of HBV vaccine at the University College Hospital (UCH), Ibadan, Nigeria. The study reviewed the records for the administration of vaccine against HBV at the Staff Medical Services Department of UCH, Ibadan, Nigeria, from 1994 to 2001. A total of 1,437 subjects consisting of 686 (47.7%) males and 751 (52.3 %) females were vaccinated against HBV from 1994 to 2001. They were aged 16 to 64 years and consisted of 356 students (24.8%) and 1081 healthcare workers (HCWs) (75.2%) which comprised Doctors (30.9%), Dentists (1.9%), Paramedics (19.6%), Non-medics (14.6%) and subjects with undisclosed occupational category ((10.7%). About 11% to 100% of the subjects had annual prescreening for HBsAg sero-negativity from 1996 to 2001 but none had post vaccination assay of anti-HBs titre. All the subjects received 1st dose of 0, 1, 2 accelerated HBV vaccination schedule while on annual basis, 16.7% to 91.8% of the subjects received the 3rd dose of the vaccine. Despite the proportional participation of the different occupational groups was highest among the doctors and dentists but lowest among the paramedics, only 59.7% of all the vaccinees had three dose(s) of the vaccine during the 8 year period. In conclusion, although the HBV vaccination programme had shortcomings, it is an established practice at UCH, Ibadan and efforts should be made to improve on its prevailing standard.Keywords: Immunization, HBV, Healthcare Workers, Nigerians, UCH, Ibadan

Affinity proteomics reveals elevated muscle proteins in plasma of children with cerebral malaria

Systemic inflammation and sequestration of parasitized erythrocytes are central processes in the pathophysiology of severe Plasmodium falciparum childhood malaria. However, it is still not understood why some children are more at risks to develop malaria complications than others. To identify human proteins in plasma related to childhood malaria syndromes, multiplex antibody suspension bead arrays were employed. Out of the 1,015 proteins analyzed in plasma from more than 700 children, 41 differed between malaria infected children and community controls, whereas 13 discriminated uncomplicated malaria from severe malaria syndromes. Markers of oxidative stress were found related to severe malaria anemia while markers of endothelial activation, platelet adhesion and muscular damage were identified in relation to children with cerebral malaria. These findings suggest the presence of generalized vascular inflammation, vascular wall modulations, activation of endothelium and unbalanced glucose metabolism in severe malaria. The increased levels of specific muscle proteins in plasma implicate potential muscle damage and microvasculature lesions during the course of cerebral malaria

Severe childhood malaria syndromes defined by plasma proteome profiles

BACKGROUND Cerebral malaria (CM) and severe malarial anemia (SMA) are the most serious life-threatening clinical syndromes of Plasmodium falciparum infection in childhood. Therefore it is important to understand the pathology underlying the development of CM and SMA, as opposed to uncomplicated malaria (UM). Different host responses to infection are likely to be reflected in plasma proteome-patterns that associate with clinical status and therefore provide indicators of the pathogenesis of these syndromes. METHODS AND FINDINGS Plasma and comprehensive clinical data for discovery and validation cohorts were obtained as part of a prospective case-control study of severe childhood malaria at the main tertiary hospital of the city of Ibadan, an urban and densely populated holoendemic malaria area in Nigeria. A total of 946 children participated in this study. Plasma was subjected to high-throughput proteomic profiling. Statistical pattern-recognition methods were used to find proteome-patterns that defined disease groups. Plasma proteome-patterns accurately distinguished children with CM and with SMA from those with UM, and from healthy or severely ill malaria-negative children. CONCLUSIONS We report that an accurate definition of the major childhood malaria syndromes can be achieved using plasma proteome-patterns. Our proteomic data can be exploited to understand the pathogenesis of the different childhood severe malaria syndromes

Musculoskeletal Disorders among Cosmetologists

A cross-sectional study was performed to investigate the relationships between physical, psychosocial, and individual characteristics and different endpoints of low back, neck, shoulder, hand/wrist and knee musculoskeletal complaints among cosmetologists in Athens, Greece. The study population consisted of 95 female and seven male beauty therapists (response rate 90%) with a mean age and duration of employment of 38 and 16 years, respectively. Neck pain was the most prevalent musculoskeletal complaint, reported by 58% of the subjects, while hand/wrist and low back complaints resulted more frequently in self-reported consequences (chronicity, care seeking and absenteeism). Significant relationships were found between self-reported physical risk factors like prolonged sitting, use of vibrating tools, reaching far and awkward body postures and the occurrence of musculoskeletal disorders at various body sites. Among psychosocial variables co-worker support and skill discretion seem to be the most important reflecting organizational problems and cognitive-behavioral aspects. The study results also suggest that effective intervention strategies most likely have to take into account both ergonomic improvements and organizational aspects

Data-driven malaria prevalence prediction in large densely populated urban holoendemic sub-Saharan West Africa

Over 200 million malaria cases globally lead to half-million deaths annually. The development of malaria prevalence prediction systems to support malaria care pathways has been hindered by lack of data, a tendency towards universal "monolithic" models (one-size-fits-all-regions) and a focus on long lead time predictions. Current systems do not provide short-term local predictions at an accuracy suitable for deployment in clinical practice. Here we show a data-driven approach that reliably produces one-month-ahead prevalence prediction within a densely populated all-year-round malaria metropolis of over 3.5 million inhabitants situated in Nigeria which has one of the largest global burdens of P. falciparum malaria. We estimate one-month-ahead prevalence in a unique 22-years prospective regional dataset of > 9 × 10^{4} participants attending our healthcare services. Our system agrees with both magnitude and direction of the prediction on validation data achieving MAE ≤ 6 × 10^{-2}, MSE ≤ 7 × 10^{-3}, PCC (median 0.63, IQR 0.3) and with more than 80% of estimates within a (+ 0.1 to - 0.05) error-tolerance range which is clinically relevant for decision-support in our holoendemic setting. Our data-driven approach could facilitate healthcare systems to harness their own data to support local malaria care pathways

Prevalence, types and demographic features of child labour among school children in Nigeria

BACKGROUND: To determine the prevalence, types and demographic features of child labour among school children in Nigeria. METHODS: A cross-sectional interview study of 1675 randomly selected public primary and secondary school pupils aged 5 to less than 18 years was conducted in the Sagamu Local Government Area of Ogun State, Nigeria from October 1998 to September 1999. RESULTS: The overall prevalence of child labour was 64.5%: 68.6% among primary and 50.3% among secondary school pupils. Major economic activities included street trading (43.6%), selling in kiosks and shops (25.4%) and farming (23.6%). No child was involved in bonded labour or prostitution. Girls were more often involved in labour activities than boys (66.8% versus 62.1%, p = 0.048): this difference was most obvious with street trading (p = 0.0004). Most of the children (82.2%) involved in labour activities did so on the instruction of one or both parents in order to contribute to family income. Children of parents with low socio-economic status or of poorly educated parents were significantly involved in labour activities (p = 0.01 and p = 0.001 respectively). Child labour was also significantly associated with increasing number of children in the family size (p = 0.002). A higher prevalence rate of child labour was observed among children living with parents and relations than among those living with unrelated guardians. CONCLUSION: It is concluded that smaller family size, parental education and family economic enhancement would reduce the pressure on parents to engage their children in labour activities
