Coping strategies of Nigerian medical students during the COVID-19 pandemic.

Objective: This study assessed the coping strategies of Nigerian medical students during the COVID-19 pandemic. Design: We conducted an online descriptive cross-sectional study among medical and dental students attending three of the largest Colleges of Medicine in the Southwestern zone of Nigeria. Settings: Our study involved students across the pre-clinical and clinical levels of the three Colleges of Medicine. Participants: We selected the respondents through a purposive sampling technique and disseminated questionnaires applied using an online survey platform (Google forms https://forms.gle/19yfEzehJKwsme759). A total of 1010 participants out of 2404 eligible students completed the questionnaires accurately, giving a response rate of 42%. Methods: The Brief-COPE questionnaire assessed the participants' coping strategies (approach and avoidant) during the COVID-19 pandemic. We conducted a bivariate analysis using the chi-square test and multiple regression analysis (p< 0.05) to determine the predictors of avoidant coping strategies. Results: Respondents mean age was 21.8±2.9 years, results were presented as Odds Ratios(OR) at 95% confidence intervals(CI). About 95% of respondents employed an approach coping strategy, while the minority(5%) adopted an avoidant coping strategy. Females were three times more likely to employ an avoidant coping strategy (OR=3.32 (95% CI 1.67-6.21) compared to male students. Conclusion: This study reveals that the majority of the respondents employed an approach coping strategy towards the COVID-19 pandemic. Females were more likely to employ an avoidant coping strategy. We recommend gender-specific programs to help medical students cope with the COVID-19 pandemic. Funding: No External Funding.

A Qualitative Study Exploring Factors Associated with Retention in HIV Care among Women with HIV in a Large HIV Clinic in Lagos, Nigeria, after Implementing the Test and Treat Policy.

Background: In Nigeria, various sociocultural and economic factors may prevent women from being retained in HIV care. This study explores the factors associated with retention in care among women with HIV in a large HIV clinic in Lagos, Nigeria, under the Test and Treat policy. Methods: Women living with HIV/AIDS (n = 24) enrolled in an HIV study at the AIDS Prevention Initiative in Nigeria (APIN) clinic in Lagos, Nigeria, were interviewed from April 1 to October 31, 2021, using a semistructured interview guide. Interviews were audio-taped, transcribed verbatim, and the themes were analyzed using the framework of Andersen and Newman's Behavioural Model for Healthcare Utilization. Results: The mean age of the respondents was 37.4 ± 9.27 years. The identified themes were as follows: being aware of the antiretroviral medications and their benefits, the household's awareness of the respondents' HIV status, and the presence of social support. Other themes were the presence of a dependable source of income and the ability to overcome the challenges encountered in obtaining income, ease of travel to and from the clinic (length of travel time and transportation costs), securing support from the clinic, challenges encountered in the process of accessing care at the clinic, and the ability to overcome these challenges. Also mentioned were self-perception of being HIV positive, motivation to remain in care, linkage to care, and intention to stay in care. Conclusion: Several deterring factors to retention in HIV care, such as nondisclosure of status, absence of social support, and clinic barriers, persist under the Test and Treat policy. Therefore, to achieve the "treatment as prevention" for HIV/AIDS, especially in sub-Saharan Africa, it is essential to employ strategies that address these barriers and leverage the facilitators for better health outcomes among women with HIV/AIDS.

Barriers and Facilitators of Fruit and Vegetable Consumption among Nigerian Adults in a Faith-Based Setting: A Pre-Intervention Qualitative Inquiry.

BACKGROUND: Inadequate consumption of fruit and vegetable is a risk factor for morbidity and mortality associated with non-communicable diseases (NCDs). An understanding of the barriers and facilitators to consumption is important for effectiveness of intervention in Africa. We present insights among church members before developing a church-based multi-component intervention to address the inadequate consumption of fruit and vegetable. METHODS: We conducted eighteen focus group discussions among 163 church members. All discussions were audio-taped, transcribed verbatim, and were analyzed for thematic content. RESULTS: We identified five main themes; Personal: awareness and knowledge of benefits, choice, habits, and curiosity, dietary restrictions and gastrointestinal symptoms following fruit and vegetable consumption. Familial: practices promoting the ready availability of fruit and vegetables in the home or habits that encourage children to eat vegetables as they transition into adulthood, pre-existing health problems of family members and the long preparation time of some traditional vegetables. Socio-cultural: Cultural practices that encourage F&V consumption, the high cost of fruits and vegetables, alternatives foregone, and cultural taboos. Environmental: inadequate farmland and storage facilities, seasonality of several fruit and vegetables, and sharp practices of force-ripening with chemicals. Church-related: inadequate space provided by the church for arable cultivation and lack of knowledge of the benefits among church leaders, church activities that involve serving fruits and vegetables and the biblical support for the consumption of fruits and vegetables. CONCLUSION: It is essential to leverage practices that promote fruit and vegetable intake and address barriers mentioned by the participants when designing such interventions.

Hepatitis B and C seroprevalence among residents in Lagos State, Nigeria: A population-based survey.

Background: Hepatitis is one of the leading causes of morbidity and mortality, particularly in developing countries. It is often caused by hepatitis B and C, which are both preventable and treatable. Available information on Hepatitis B and C in Nigeria is based primarily on estimates obtained from specific population sub-groups or hospital-based surveys leaving gaps in population-level knowledge, attitudes, and prevalence. This study aimed to assess the knowledge, attitude and associated factors of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections amongst residents of Lagos State. Methodology: This was a community-based descriptive cross-sectional study carried out in all the 20 local government areas of Lagos state using a multistage sampling technique. Data were collected using pre-tested interviewer-administered questionnaires. Blood samples were taken (pinprick) from respondents (n = 4862) and tested using hepatitis B and C surface antigen tests after obtaining informed consent. Results: The overall prevalence of HBV infection in Lagos State was 2.1% while the prevalence of HCV infection was 0.1%. Only about half of all the respondents (50.9%) had heard about hepatitis B before the survey. Knowledge of the specific symptoms of HBV was also very low. For instance, only 28.1% of the respondents knew that yellowness of the eyes is associated with hepatitis while < 1% (0.1%) knew that HBV infection is associated with the passage of yellow urine. The most common source of information about hepatitis was the radio (13.0%). Only 36.2% of the respondents knew that HBV infection could be prevented. Overall, 28.8% of the respondents were aware of the hepatitis B vaccine. Less than half (40.9%) felt it was necessary to get vaccinated against HBV, however, a similar proportion (41.9%) would want to be vaccinated against HBV. Only 2.5% of all the respondents had ever received HBV vaccines while 3.5% had ever been tested for hepatitis B before this survey. There was a statistically significant association between HBV infection and respondents' use of shared clippers and work exposure involving contact with body parts and body fluids (P < 0.05). Conclusion: The knowledge, awareness and risk perception of HBV infection were low, however, almost half of the residents were willing to receive hepatitis B vaccinations if offered. It is recommended that the population-based prevention programmes and regular community-based surveillance be conducted by the public health department of Lagos State Ministry of Health. In addition, the strengthening of routine immunisation and vaccination of high-risk groups should be prioritised.

Feasibility and acceptability of early infant screening for sickle cell disease in Lagos, Nigeria-A pilot study.

In Nigeria, about 150000 babies are born annually with sickle cell disease (SCD), and this figure has been estimated to increase by 100% by the year 2050 without effective and sustainable control strategies. Despite the high prevalence, newborn screening for SCD which allows for early prophylactic treatment, education of parents/guardians and comprehensive management is not yet available. This study explored a strategy for screening in early infancy during the first and second immunization visits, determined the prevalence, feasibility and acceptability of early infant screening for SCD and the evaluation of the HemoTypeSC diagnostic test as compared to the high-performance liquid chromatography (HPLC) gold standard. A cross-sectional study was conducted in two selected primary health care centres in Somolu local government area (LGA) in Lagos, Nigeria. Two hundred and ninety-one mother-infant pairs who presented for the first or second immunization visit were consecutively enrolled in the study following written informed consent. The haemoglobin genotype of mother-infant pairs was determined using the HemoTypeSC rapid test kit. Confirmation of the infants' Hb genotype was done with HPLC. Data were analysed with SPSS version 22. Validity and Predictive value of HemotypeSC rapid screening test were also calculated. Infant screening for SCD was acceptable to 86% of mothers presenting to the immunization clinics. The prevalence of SCD among the infant cohort was 0.8%. The infants diagnosed with SCD were immediately enrolled in the paediatric SCD clinic for disease-specific care. The HemoTypeSC test had 100% sensitivity and specificity for sickle cell disease in early infancy compared to HPLC. This study affirms that it is feasible and acceptable for mothers to implement a SCD screening intervention program in early infancy in Lagos State. The study also demonstrates the utility of the HemotypeSC rapid testing for ease and reduced cost of screening infants for SCD.

Evolutionary trends of the COVID-19 epidemic and effectiveness of government interventions in Nigeria: A data-driven analysis.

Background: Nigeria became the first sub Saharan African country to record a case of COVID-19 after an imported case from Italy was confirmed on February 27, 2020. Moving averages and the Epidemic Evaluation Indices (EEI) are two important but complementary methods useful in monitoring epidemic trends, they can also serve as a useful guide for policy makers and inform the timing of decisions on preventive measures. The objectives of this paper are to graphically depict the trends of new COVID-19 cases nationally and in two key States (Lagos and Kano) and the Federal Capital Territory (FCT) using the moving averages and the EEI. In addition, we examined the effects of government's public health interventions on the spread of COVID-19 and appraise the progress made so far in addressing the challenges of COVID-19 in Nigeria. Methods: We used data on new cases of COVID-19 from public sources released by the Nigeria Center for Disease Control (NCDC) from the 27th February 2020, when the first case was recorded, to 11th May, 2020, one week after the lockdowns in Lagos and the FCT were lifted. We computed moving averages of various orders, the log transformations of the moving averages and then the EEIs of new COVID-19 cases for Nigeria as a whole, and then for two of the most affected states i.e. Lagos and Kano, as well as the Federal Capital Territory (FCT). Then, we plotted graphs to depict these indices and show the epidemic trends for COVID-19 in each scenario. Results: Nationally, the number of new cases of COVID-19 showed an initial gradual rise from the first reported case on the 27th February 2020. However, by the second week in April, these numbers began to show a relatively sharper increase and this trend has continued till date. Similar trends were observed in Lagos state and the FCT. The rate of growth of the logarithm-transformed moving average in the period leading to, and including the lockdowns reduced by a factor of 0.65. This suggests that the policies put in place by the government including the lockdown measures in Lagos and the FCT may have had a positive effect on the development of new cases of COVID-19 in Nigeria. Nationally and in Lagos, the EEIs of the COVID-19 cases started off on very high notes, however, the effects of the lockdown gradually became evident by the end of April and early May 2020, as the EEIs headed closer to 1.0. In all case scenarios, the EEIs are still above 1.0. Conclusions and recommendations: The number of new cases of COVID-19 has been on a steady rise since the first reported case. In Nigeria especially across the two states and the FCT, public health interventions including the lockdown measures appear to have played a role in reducing the rate of increase of new infections. The EEIs are still above 1.0, suggesting that despite the progress that appears to have been made, the epidemic is still evolving and Nigeria has not yet reached her peak for COVID-19 cases. We recommend that aggressive public health interventions and restrictions against mass gatherings should be sustained.

Tobacco related knowledge and support for smoke-free policies among community pharmacists in Lagos state, Nigeria.

BACKGROUND: There are no safe levels of exposure to second hand smoke and smoke-free policies are effective in reducing the burden of tobacco-related diseases and death. Pharmacists, as a unique group of health professionals, might be able to play a role in the promotion of smoke-free policies. OBJECTIVE: To determine the tobacco-related knowledge of community pharmacists and assess their support for smoke-free policies in Lagos state, Nigeria. METHODS: A cross-sectional descriptive study design using both quantitative and qualitative methods was employed. Two hundred and twelve randomly selected community pharmacists were surveyed using a pre-tested self-administered questionnaire. In addition, one focus group discussion was conducted with ten members of the Lagos state branch of the Association of Community Pharmacists of Nigeria. RESULTS: The quantitative survey revealed that the majority (72.1%) of the respondents were aged between 20 and 40 years, predominantly male (60.8%), Yoruba (50.2%) or Igbo (40.3%) ethnicity and had been practicing pharmacy for ten years or less (72.2%). A majority (90.1%) of respondents were aware that tobacco is harmful to health. Slightly less (75.8%) were aware that second hand smoke is harmful to health. Among the listed diseases, pharmacists responded that lung (84.4%) and esophageal (68.9%) cancers were the most common diseases associated with tobacco use. Less than half of those surveyed associated tobacco use with heart disease (46.9%), chronic obstructive pulmonary disease (27.8%), bladder cancer (47.2%), peripheral vascular disease (35.8%) and sudden death (31.1%). Only 51.9% had heard of the World Health Organization Framework Convention on Tobacco Control (WHO FCTC). A little over half of the respondents (53.8%) were aware of any law in Nigeria controlling tobacco use. The majority of respondents supported a ban on smoking in homes (83.5%), in public places (79.2%), and in restaurants, nightclubs and bars (73.6%). For every additional client attended to daily, knowledge scores increased by 0.022 points. Current smokers were 1.3 times less likely to support smoke-free policies compared with non-smokers. The findings emanating from the focus group discussion reinforced the fact that the pharmacists were in support of smoke-free policies particularly in homes and public places. It also demonstrated that most of them were aware of the health risks associated with tobacco use and second hand smoke however some misconceptions seemed to exist. CONCLUSION: The pharmacists surveyed expressed support of smoke-free policies and most of them were aware of the health risks associated with tobacco use. However, awareness of WHO FCTC and country-level tobacco legislation was low. Current smokers were less likely to support smoke-free policies. Community pharmacists should therefore be considered worth engaging for the promotion of smoke-free policies. Efforts should also be made to educate pharmacists about country level smoke-free laws.

Tobacco related knowledge and support for smoke-free policies among community pharmacists in Lagos state, Nigeria / Conocimiento sobre el tabaco y apoyo a las políticas sin humo entre los farmacéuticos comunitarios del estado de Lagos, Nigeria

Antecedentes: No hay niveles seguros de exposición de fumador pasivo y las políticas de sin-humo han mostrado ser efectivas en la reducción del daño de las enfermedades y muertes producidas por tabaco. Los farmacéuticos, como grupo destacado de profesionales de la salud, pueden jugar un papel en la promoción de políticas sin-humo. Objetivo: Determinar el conocimiento sobre el tabaco de los farmacéuticos comunitarios y su apoyo a políticas sin-humo en el estado de Lagos, Nigeria. Métodos: Se utilizó un estudio transversal usando tanto métodos cuantitativos como cualitativos. Se entrevistó a 212 farmacéuticos comunitarios aleatoriamente seleccionados utilizando un cuestionario autoadministradopre-pilotado. Además, se realizó una discusión en grupo focal con 10 farmacéuticos de la sección del estado de Lagos de la Asociación de Farmacéuticos Comunitarios de Nigeria. Resultados: El cuestionario cuantitativo reveló que la mayoría (72,1%) de los respondentes tenían entre 20 y 40 años, eran predominantemente hombres (60,8%), de las etnias Yoruba (50,2%) o Igbo (40,3%) y estaban ejerciendo durante 10 años o menos (72,2%). La mayoría (90,1%) sabía que el tabaco es malo para la salud. Ligeramente menos (75,8%) sabía que ser fumador pasivo es malo para la salud. Entre las enfermedades identificadas, los farmacéuticos respondieron que los canceres de pulmón (84,4%) y de esófago (68,9%) eran las enfermedades más frecuentemente asociadas con el tabaco. Menos de la mitad de los entrevistados asoció el tabaco con enfermedad cardiaca (46,9%), enfermedad pulmonar obstructiva crónica (27,8%), cáncer de vejiga (47,2%), enfermedad vascular periférica (35,8%) y muerte súbita (31,1%). Sólo el 51,9% había oído sobre el World Health Organization Framework Convention on Tobacco Control (WHO FCTC). Algo más de la mitad de los respondentes (53,8%) conocía la ley en Nigeria sobre el control de tabaco. La mayoría de los respondentes apoyaba la prohibición de fumar en los hogares (83,5%), en lugares públicos (79,2%) y en restaurantes, clubs nocturnos y bares (73,6%). Por cada cliente de más atendido en la farmacia, las puntuaciones de conocimiento crecían en 0.022 puntos. Los actuales fumadores tenían 1,3 veces menos de probabilidad de apoyar políticas sin-humo que los no fumadores. Los hallazgos del grupo focal reforzaron el hecho de que los farmacéuticos apoyan las políticas sin-humo, especialmente en los hogares y lugares públicos. También demostraron que la mayoría de ellos conocían los riesgos del tabaco y de los fumadores pasivos, aunque parecía haber algunos errores de concepto. Conclusión: Los farmacéuticos entrevistados apoyaron las políticas sin-humo y la mayoría conocía los riesgos asociados al uso de tabaco. Sin embardo, el conocimiento del WHO FCTC y de la legislación era bajo. Era menos probable que los fumadores apoyasen las políticas sin-humo. Debería considerarse valioso enrolar a los farmacéuticos comunitarios en la promoción de políticas sin-humo. Deberían realizarse esfuerzos para educar a los farmacéuticos sobre la legislación nacional sobre tabaco (AU)

Tobacco-free schools as a core component of youth tobacco prevention programs: a secondary analysis of data from 43 countries.

BACKGROUND: Preventing tobacco use is a key aspect of health promotion during adolescence. We assessed prevalence and impact of school-based tobacco prevention programs in 43 countries. METHODS: We performed a secondary analysis of national data of students aged 13-15 years (Global Youth Tobacco Surveys) from 43 countries during 2005-2011. National surveys of the corresponding school personnel (Global School Personnel Surveys) were performed in each country during the same year as the student surveys. Data on status of enforcement of national smoke-free school policies were obtained from the 2008 and 2009 WHO MPOWER reports. Logistic regression was used to measure ecologic-level associations between school-based tobacco prevention programs and tobacco-related knowledge and behaviour among students (P < 0.05). RESULTS: The proportion of students who were taught in class about the dangers of tobacco use during the school year ranged from 31.4% (Georgia) to 83.4% (Papua New Guinea). For every 10% increase (country level) in the proportion of teachers who reported having a tobacco prevention curriculum in their school, the odds of students reporting exposure to education in class about the dangers of tobacco increased by 6.0% (AOR = 1.06; 95% CI: 1.04-1.08). However, didactic education in class about the dangers of tobacco use was not independently associated with student current cigarette smoking behavior. Conversely, the likelihood of being a current smoker was significantly lower among students in countries with moderate/strongly enforced national smoke-free school policies compared with those in countries with poorly enforced/no national smoke-free school policies (AOR = 0.59; 95% CI: 0.45-0.76). CONCLUSIONS: Comprehensive tobacco prevention programs that include well-enforced smoke-free school policies may help reduce youth smoking.

Results from Nigeria's 2013 Report Card on Physical Activity for Children and Youth.

BACKGROUND: Physical activity (PA) promotion in children and youth is an impetus for prevention and control of NCD morbidity and mortality, but evidence is needed for effective interventions. The aim of the present paper is to summarize the results of the 2013 Nigerian Report Card on Physical Activity for children and youth. METHODS: The Technical Report Committee conducted a comprehensive review of available literature in Nigeria. Grades were assigned to 10 PA indicators modeled after the Active Healthy Kids Canada (AHKC) grading system. RESULTS: Specific grades were assigned for several indicators: Overall Physical Activity Levels, C; Organized Sport and Physical Activity Participation, Incomplete; Active Play and Leisure, C-; Active Transportation, B; Sedentary Behaviors, F; Overweight and Obesity, B+. The following indicators were graded as INCOMPLETE: Physical Activity in School setting, Family and Peers, Community and Built Environment, and Government Strategies and Investments. CONCLUSIONS: PA levels of Nigerian children and youth are moderate while sedentary behaviors are high. The development of national guidelines for PA and sedentary behaviors can better inform policy and practice on healthy living among Nigerian children and youth.

Support for smoke-free cars when children are present: a secondary analysis of 164,819 U.S. adults in 2010/2011.

UNLABELLED: Comprehensive smoke-free legislations prohibiting smoking in indoor areas of workplaces, bars, and restaurants have been adopted in most of the USA; however, limited efforts have focused on regulating secondhand smoke (SHS) exposure in the family car. The objective of this study was to identify the determinants and national/state-specific population support for smoke-free cars, in the presence of any occupant in general, but particularly when children are present. National data of US adults aged ≥18 years (n = 164,819) were obtained from the 2010/2011 Tobacco Use Supplement of the Current Population Survey. Among all US adults, a significantly greater proportion supported smoke-free cars when it was specified that the occupant was a child compared to when not specified (93.4 vs. 73.7 %, p < 0.05). Age, race/ethnicity, gender, current tobacco use, marital status, and the existence of household smoke-free regulations all mediated population support for smoke-free cars. CONCLUSION: While differences within the US population were noted, this study however showed overwhelming support for smoke-free car policies, particularly when children are present. Policies which prohibit smoking in indoor or confined areas such as cars may benefit public health by protecting nonsmoking children and adults from involuntary SHS exposure.

Poly-tobacco use among adults in 44 countries during 2008-2012: evidence for an integrative and comprehensive approach in tobacco control.

INTRODUCTION: The concurrent use of multiple tobacco products (i.e., poly-tobacco use) might hinder efforts to reduce overall tobacco use, particularly considering that use of some non-cigarette tobacco products may be popular in some regions due to social, cultural, or economic reasons. This study assessed poly-tobacco use patterns among persons aged ≥15 years old from 44 countries. METHODS: Data from 44 countries in all six World Health Organization regions were obtained from the 2008 to 2012 Global Adult Tobacco Surveys (n=19 countries), and the Special Eurobarometer 385 (77.1) survey, 2012 (n=25 countries). Correlates of poly-tobacco use were assessed using multivariate logistic regression analyses (p<0.05). RESULTS: Overall prevalence of poly-tobacco use ranged from 0.8% (Mexico) to 11.9% (Denmark). In 28 countries, 20% or more of current smokers of manufactured cigarettes concurrently used at least one other tobacco product and this proportion was highest in India (66.2%) and lowest in Argentina (4.4%). After adjusting for other factors, the likelihood of being a poly-tobacco user among all respondents was lower among females (aOR=0.09; 95% CI: 0.08-0.11), and among respondents from upper-middle-income (aOR=0.53, 95% CI: 0.43-0.66), and lower-middle-income countries (aOR=0.64; 95% CI: 0.51-0.81) compared to high-income countries. Increased likelihood of poly-tobacco use was observed among respondents from the South-East Asian region compared to those from the European region (aOR=1.58, 95% CI: 1.35-1.85), as well as among respondents aged ≥65 years (aOR=2.10; 95% CI: 1.73-2.54), compared to those aged <25 years. CONCLUSIONS: The pattern of tobacco use varied widely, underscoring the need for intensified efforts towards implementing policies that address all tobacco products, not only manufactured cigarettes.

Sociodemographic correlates of exclusive and concurrent use of smokeless and smoked tobacco products among Nigerian men.

INTRODUCTION: This study sought to determine the sociodemographic correlates of exclusive and concurrent use of smokeless tobacco (SLT) and smoking (i.e., dual use) and to explore the association between SLT use and the amount of cigarettes smoked per day. METHODS: Data were obtained from a nationally representative sample of Nigerian men aged 15-59 years (N = 15,453) who participated in the 2008 Nigerian Demographic and Health Survey (NDHS). The NDHS used an interviewer-administered questionnaire to collect data on participants' sociodemographic characteristics and tobacco use status. Taking account of the multistage sampling used in the NDHS, data analyses included descriptive statistics, chi-square analysis, and multivariable adjusted multinomial logistic regression analysis. RESULTS: Of the respondents, 12.2% (n = 1,842) were tobacco users, out of which 24.5% (n = 477) were exclusive SLT users, 69% (n = 1,236) were exclusive smokers, and 6.5% (n = 129) were dual users. Both SLT use and smoking were most prevalent among the Igbo ethnic group and among the least educated men. SLT use was most prevalent among those in the southeast (9.75%) and north-central (7.71%) regions, where smoking was also common. The number of cigarettes smoked per day was not significantly different among dual users when compared with exclusive smokers (7.3 vs. 5.6; p = .088). Dual users were also more likely to self-identify as traditionalists (RRR = 6.03; 95% CI = 2.96-12.28) compared with self-identifying as practicing Islam or Christianity. CONCLUSIONS: There are distinctive ethnic and regional differences in tobacco use patterns among Nigerian men, and SLT use was not associated with reduced smoking intensity among dual users.

Sexually transmitted infections: prevalence, knowledge and treatment practices among female sex workers in a cosmopolitan city in Nigeria.

Sexually transmitted infections constitute economic burden for developing countries, exposure to causative agents is an occupational hazard for female sex workers. Targeted interventions for this population can reduce the incidence and prevalence of sexually transmitted infections including human immunodeficiency virus, but barriers exists which can hinder effective implementation of such programs. This descriptive cross sectional study sought to assess the prevalence, knowledge and treatment practices of sexually transmitted infections among brothel based female sex workers. Three hundred and twenty three consenting female sex workers were surveyed using pre tested, interviewer administered questionnaires. More than half of the respondents (54.2%) had poor knowledge of symptoms of sexually transmitted infections. Only 13.9% were aware that sexually transmitted infections could be asymptomatic. The self reported prevalence of symptomatic sexually transmitted infections was 36.5%. About half of those with sexually transmitted infectionss sought treatment in a hospital or health centre while 32.5% from a patent medicine vendor. Most respondents (53.8%) mentioned the perceived quality of care as the main reason for seeking treatment in their chosen place. More of the respondents with good knowledge of sexually transmitted infections reported symptoms compared to those with fair and poor knowledge. The knowledge of sexually transmitted infections among these female sex workers is poor and the prevalence is relatively high. Efforts to improve knowledge promote and encourage preventive as well as effective treatment practices must be made for this population.
