Knowledge and sociodemographic predictors of shisha smoking among students in a Nigerian university.

Background: There is a global rise in shisha smoking amongst the youths. Information on the prevalence and knowledge of the constituents and the harmful effects of shisha smoking is important for the development of prevention strategies and policies. Aim: This cross-sectional study aimed to assess the knowledge and sociodemographic predictors of shisha smoking among the university students. Subjects and Methods: A structured 12-item questionnaire was administered to the university students at the University of Port Harcourt, Rivers State. The prevalence, knowledge, and predictors of shisha smoking and the association between sociodemographic factors were studied. A P value of <0.05 was considered statistically significant. Results: Among the 546 university students studied, 24.7% (135) had smoked shisha. The percentage of those knowledgeable about the constituents and its ill effects of shisha smoking was 14.8% (81), those with poor knowledge was 94.1% among shisha smokers. Females and social sciences students demonstrated statistically significant better knowledge of shisha (P = 0.007, and 0.027, respectively). The main predictors of shisha smoking were: poor knowledge (odd ratio, OR = 4.48, 95% confidence interval, CI [2.02, 9.93], P = 0.001), being in 400 level of study (OR = 2.63, 95% CI [1.12, 6.13], P = 0.724) and being in the faculty of social science (OR = 1.25, 95% CI [0.50, 3.09], P = 0.638). Conclusions: The prevalence of shisha smoking in this study was 24.7%, and the most influential factors were the level of study, type of faculty, and knowledge of the constituents and harmful effects of shisha. Lecturers and administrators of different faculties of the university should be engaged to include shisha smoking prevention programs in their curriculum.

Standard Precautions and Hepatitis B Virus Vaccination among Doctors and Clinical Students in a Nigerian Tertiary Hospital: Data from a Pre-COVID Era.

BACKGROUND: Adherence to standard precautions in hospitals is vital to control the spread of hospital-acquired infections (HAIs). OBJECTIVE: To determine the level of compliance to standard precautionary measures by clinical students and doctors in a Nigerian tertiary hospital to curb spread of infectious diseases, with focus on uptake of Hepatitis B Virus (HBV) vaccine. METHODS: This study which involved 228 participants used self-administered questionnaire to obtain data on respondents' biodata, history of exposure to patient's body fluids (PBF) in the last six months, HBV vaccination status, use and recapping of needles, handwashing, and use of Personal Protective Equipment (PPE). Data analysis was done using SPSS version18; associations were tested with Chi-square statistics, and p<0.05 was considered significant. RESULTS: Of the 228 respondents, 113(49.6%) were clinical students and 115 (50.4%) doctors with mean age of 27.61±7.48 years. A total of 140 (61.4%) respondents had been exposed to PBF: [89 (63.6%) doctors, 51(36.4%) students]. Age, student/doctor category, and number of years of practice all affected exposure to PBF (p<0.05). Recapping of needles was practiced by 167 (73.2%); hand-washing by 225 (98.7%), and lack of running water was the commonest reason for non-compliance. Also, 218 (95.6%) and 123 (53.9%) wore handgloves and face-masks respectively when attending to patients while 111 (48.7%) received at least a dose of HBV vaccine: [72 (64.9%) doctors, 39 (35.1%) students; p<0.05] but only 60.3% completed their doses. CONCLUSION: Majority had good hand-washing practice, but only about half wore face-masks while working, and recapping of needles was prominent. Doctors had more occupational exposure to PBF but received more HBV vaccine although many were yet to complete their doses. With COVID-19 added to existing list of HAIs, there is need to scale-up compliance to infection control practices through sustained training programs and better health policies which would also drive vaccine coverage in this population.

CONTEXTE: Le respect des précautions standard dans les hôpitaux est essentiel pour contrôler la propagation des infections nosocomiales (IHA). OBJECTIF: Déterminer le niveau de conformité aux mesures de précaution standard par les étudiants cliniques et les médecins d'un hôpital tertiaire nigérian pour limiter la propagation des maladies infectieuses, en mettant l'accent sur l'absorption du vaccin contre le virus de l'hépatite B (VHB). MÉTHODES: Cette étude qui a impliqué 228 participants a utilisé un questionnaire auto-administré pour obtenir des données sur les biodonnées des répondants, les antécédents d'exposition aux fluides corporels (PBF) du patient au cours des six derniers mois, le statut de vaccination contre le VHB, l'utilisation et le récapitulation des aiguilles, le lavage des mains et l'utilisation de l'équipement de protection individuelle (EPI). L'analyse des données a été effectuée à l'aide de SPSS version18; les associations ont été testées avec des statistiques sur le chi carré et inférieur ou égal à 0,05 a été considéré comme significatif. RÉSULTATS: Sur les 228 répondants, 113 (49,6%) étaient des étudiants cliniques et 115 (50,4%) des médecins avec un âge moyen de 27,61 ± 7,48 ans. Au total, 140 (61,4%) répondants avaient été exposés à la FPB: [89 (63,6%) médecins, 51 (36,4%) étudiants]. Âge, catégorie étudiant / médecin et nombre d'années de pratique, toutes les expositions au FPB (p <0,05) ont été affectées. Le récapitulation des aiguilles a été pratiqué par 167 (73,2%); lavage des mains par 225 (98,7%), et le manque d'eau courante était la raison la plus courante de non-conformité. De plus, 218 (95,6%) et 123 (53,9%) portaient des gants et des masques pour le visage respectivement lorsqu'ils s'occupaient de patients tandis que 111 (48,7%) recevaient au moins une dose de vaccin contre le VHB: [72 (64,9%) médecins, 39 (35,1%) étudiants. CONCLUSION: la majorité avait une bonne pratique de lavage des mains, mais seulement environ la moitié portait des masques faciaux pendant le travail, et le récapitulation des aiguilles était important. Les médecins étaient plus exposés au PBF mais ont reçu plus de vaccin contre le VHB, bien que beaucoup n'aient pas encore terminé leurs doses. Avec COVID-19 ajouté à la liste existante des HAI, il est nécessaire d'augmenter la conformité aux pratiques de contrôle des infections grâce à des programmes de formation soutenus et à de meilleures politiques de santé qui favoriseraient également la couverture vaccinale dans cette population. Mots clés: précautions standard, exposition professionnelle; Infections nosocomiales; Vaccin contre le VHB.

Fluoride content of commercial drinking water and carbonated soft drinks available in Southeastern Nigeria: dental and public health implications.

OBJECTIVE AND AIM: The importance of fluoride in preventing dental diseases cannot be overemphasized. The aim of this study was to determine the fluoride content of commercial bottled water, sachet water and carbonated soft drinks available in Southeastern-Nigeria at the same time, eliciting their dental and public health implications. METHOD: Determination of fluoride level in water and carbonated drinks was carried out using Colorimetric-SPADNS (Trisodium 2-(4-sulfophenylazo)-1, 8-dihydroxynaphthalene-3, 6-disulfonate) method. This is a simple and rapid technique with high accuracy. 10 brands of bottled water, 10 brands of carbonated soft drinks and 20 brands of sachet water were studied. The experiment for each brand was carried out in duplicates and mean fluoride concentrations generated. Data analysis was done using SPSS version 17. RESULTS: Fluoride contents in mg/L of bottled water brands ranged from 0.0173 ± 0.0019 mg/L to 0.1607 ± 0.0630 mg/L [mean: 0.0442 ± 0.0184 mg/L] and that of sachet water brands was from 0.0131 ± 0.0019 mg/L to 0.1754 ± 0.1344 mg/L. Mean fluoride content of carbonated soft drinks was 0.0228 ± 0.0064 mg/L with one of the brands having as low as 0.0066 ± 0.0028 mg/L fluoride. CONCLUSION: None of the drinks investigated contained level of fluoride up to standard admissible values suggesting sub-optimal intake. As the suitability of advice on fluoride use in preventing dental abnormalities depends on the individual's total fluoride intake from drinks and other sources, a further study is warranted to relate this total with the baseline decayed missing and filled teeth of the population.

Tobacco use and oral health of inmates in a Nigerian prison.

OBJECTIVES: To determine the effect of tobacco use on oral health status of inmates of a federal prison in Enugu, Nigeria. MATERIALS AND METHODS: The study involved 230 inmates of the Nigerian Prison in Enugu. An interviewer-administered questionnaire was used to collect data on the demographic characteristics of the participants, oral hygiene methods, and smoking habits. An intra-oral examination to determine their oral health status was done using simplified oral hygiene index (OHI-S) for the oral hygiene status, the modified decayed missing and filled teeth (DMFT) index for caries status, and community periodontal index of treatment needs (CPITN) for the periodontal needs. Statistical Package for Social Sciences software, version 15 was used to analyze data. RESULTS: One hundred and twenty participants (52.2%) were current smokers. Mean DMFT of smokers and nonsmokers were 2.38 ± 0.71 and 2.25 ± 0.83 respectively ( P = 0.508) while mean Community Periodontal Index (CPI) scores of smokers and nonsmokers were 4.71 ± 1.26 and 2.27 ± 0.86, respectively ( P = 0.276). Oral soft tissue lesions such as mucosal burn, oral leukoplakia-like lesions were found mainly in the tobacco users. CONCLUSION: Tobacco use had a negative effect on the oral health of the participants as smokers had worse oral health profile than non-smokers. They may benefit from counseling programs with the view to educate them on the effect of tobacco use on oral health and by extension, the general health. The full implementation of the Framework Convention on Tobacco Control (FCTC) treaty in Nigeria could help in curtailing these unwanted consequences of tobacco use.

Assessing health workers knowledge on the determinants of health: a study in Enugu Nigeria.

BACKGROUND: Different social economic and personal factors have been touted as determining a person's health. This encompasses a person's living environment, economic status, genetic makeup, physical attributes and not just access to health services. It is important that health workers recognize that a person's socio-economic environment can have an adverse effect on the health status ofthe individual so as to capture this aspect in their choice of intervention. METHODS: The study was carried out in two tertiary institutions in Enugu state selected purposively because they housed a dental clinic. It was a descriptive cross sectional study consisting of 87 participants which represented all the dental taff available during the study period. The participants were interviewed with a structured questionnaire used to elicit the knowledge of health workers on health determinants. RESULTS: When individual factors were considered, a greater percentage of health workers, believed that safe drinking water (98.9%), where a person lives (96.6%) and a balanced diet, affect health more than availability of health services (59.8%) or the ability of the health care system to meet the needs of the people (55.2%). However when ranking the magnitude of the contribution of the various determinants of health the majority (37.9%) considered a good health care system the most important contributory factor to determining health of a community while social environment (14.9%) was the least. CONCLUSION: The ranking of good healthcare system over social environment points to the emphasis being laid on curative instead of preventive management of diseases, which have been entrenched in our health workers. Considerations should therefore be made for public health institutions to dwell more on health promotion and education activites on the importance of the social determinatants on health.

Attendance pattern amongst patients at the Dental Clinic of the University of Nigeria Teaching Hospital, Enugu, Nigeria.

OBJECTIVE: Dental clinic attendance is one of the indicators of health behaviour which will ultimately impact on the oral health. This study aimed at determining the patients' attendance pattern and the reasons for attendance at the Dental clinic of the University of Nigeria Teaching Hospital (UNTH), Enugu. METHODS: A retrospective study was done using the record book of the Oral Diagnosis unit of the Dental clinic in UNTH. Data on patients' age, gender, presenting complaint(s) at first visit were obtained from these books. Patients with incomplete records were omitted. The data were analysed statistically using Statistical Package for Social Sciences (version 15); frequencies of all relevant variables were generated and Chi-square test was used to compare categorical variablesatp < 0.05. RESULTS: Data of 1663 patients with mean age of 33.2 +/- 18 years were obtained. Six hundred and eighty six (41.3%) were males while 977 (58.7%) were females; a statistically significant difference was found in the quarterly attendances of males and females (p < 0.05). The 20-29 and the 0-9 years age groups had 36.1% and 6.5% records respectively. Eight hundred and twenty five (49.2%) visited clinic because of pain, 7.6% for swellings in the mouth and 5.7% were without symptom but attended for routine check ups cum professional tooth cleaning. CONCLUSION: Asymptomatic dental clinic attendance was not common in this report; attendances were mostly prompted by pain. More females than males attended clinic and the second quarter of the year witnessed the highest turn out of patients.

Comparison of normative and self-perceived dental needs among adolescents in Lagos, Nigeria.

AIMS AND OBJECTIVES: Professionally determined needs as well as self-perceived oral health needs play significant roles in the assessment of needs for dental care. The aim of this study was to compare the self-perceived oral health needs by the adolescents with professionally determined needs by the oral health-care giver. SUBJECTS AND METHODS: This was a community-based cross-sectional study involving 504 adolescents who were selected through multistage random sampling from secondary schools in Lagos State. Self-assessed oral health needs was measured by the participants' response to the question(s): How can you describe the condition of your teeth/gum? Their response was compared to the findings of an intra-oral examination of the participants (after an informed consent) carried out under field conditions by one examiner employing DMFT and CPITN indices for Dental Caries and Periodontal status respectively. RESULTS: The prevalence of Dental Caries was 11.9% while that of Periodontal disease was 60.4%. The Sensitivity, Specificity, Positive and Negative Predictive Values for Dental Caries were 30%, 85%, 21.4% and 89.9% respectively; and 21.7%, 80.9%, 63.4%, and 32.9% respectively for Periodontal status. CONCLUSION: Self-perceived oral health needs assessed by questionnaire among adolescents was found to be at variance with the clinically determined needs. Promotion of oral health awareness among adolescents with emphasis on recognition of signs and symptoms of common dental diseases using the school as a base is strongly advised.
