Clinical students' perception of educational environment in a Nigerian university: a mixed method study.

BACKGROUND: Learning environment (LE) research has been given priority in higher education institutions globally because of its influence on learning processes and outcomes. Although studies reporting the perceptions of health science students about LE in Nigeria are available, none have compared the perceptions of students from different health professions. Therefore, this study aimed to assess final-year clinical students' perceptions of their LE from four programs (dentistry, medicine, nursing, and physiotherapy) and compared their LE perceptions. METHODS: This study adopted a cross-sectional study design using a mixed method approach. The quantitative survey involved all the final-year clinical students at the University of Ibadan, and they completed the Dundee Ready Education Environment Measure (DREEM) questionnaire. The qualitative aspect involved 24 consenting students in four focus group discussions. RESULTS: A total of 214 out of 223 copies of the DREEM questionnaire were duly completed and returned, yielding 96.0% response rate. The participants' mean age was 24 ± 2.3 years (ranged between 22 and 25 years, p = 0.001). The mean DREEM scores of the students from the four programs ranged between 119.68 ± 18.02 and 147.65 ± 15.89 out of a maximum of 200, interpreted as more positive than negative perceptions of LE. Physiotherapy students' DREEM score was significantly higher than those of medical, dental, and nursing students (p < 0.001). The DREEM scores of other students did not differ significantly (p > 0.05). Dental and medical students had similar positive perceptions. The qualitative aspect revealed that the students had positive perceptions of their teachers' knowledge base and self-acquisition of knowledge but negative perceptions of their teachers' communication skills, infrastructural facilities, lecturer-student relationships, and hostel accommodations. CONCLUSION: Although the survey indicated that these clinical students had more positive than negative perceptions of their learning environment, the qualitative aspect of the study revealed many challenges that the students were confronted with. The clinical students' perception of their learning environment could be improved if the university authorities would address these challenges.

Influence of well-being and quality of work-life on quality of care among healthcare professionals in southwest, Nigeria.

The Nigerian healthcare industry is bedevilled with infrastructural dilapidations and a dysfunctional healthcare system. This study investigated the influence of healthcare professionals' well-being and quality of work-life (QoWL) on the quality of care (QoC) of patients in Nigeria. A multicentre cross-sectional study was conducted at four tertiary healthcare institutions in southwest, Nigeria. Participants' demographic information, well-being, quality of life (QoL), QoWL, and QoC were obtained using four standardised questionnaires. Data were summarised using descriptive statistics. Inferential statistics included Chi-square, Pearson's correlation, independent samples t-test, confirmatory factor analyses and structural equation model. Medical practitioners (n = 609) and nurses (n = 570) constituted 74.6% of all the healthcare professionals with physiotherapists, pharmacists, and medical laboratory scientists constituting 25.4%. The mean (SD) participants' well-being = 71.65% (14.65), QoL = 61.8% (21.31), QoWL = 65.73% (10.52) and QoC = 70.14% (12.77). Participants' QoL had a significant negative correlation with QoC while well-being and quality of work-life had a significant positive correlation with QoC. We concluded that healthcare professionals' well-being and QoWL are important factors that influence the QoC rendered to patients. Healthcare policymakers in Nigeria should ensure improved work-related factors and the well-being of healthcare professionals to ensure good QoC for patients.

Preliminary study of perceived cardiovascular disease risk and risk status of adults in small rural and urban locations in Ibadan, Nigeria.

The burden of cardiovascular disease (CVD) has been on the rise in developing countries like Nigeria recently. Studies on perceived CVD risk and the risk status of adults in Ibadan are not readily available, hence this study. A mixed-method design involving a cross-sectional survey and an exploratory qualitative study was utilized. Convenience sampling was used to recruit 418 participants (209 from rural and 209 from urban) for the cross-sectional survey, while purposive sampling was used to recruit 14 participants for the qualitative aspect. The INTERHEART risk score and the Perception of Risk of Heart Disease Scale were used to investigate participants' CVD risk status and perceived risk, respectively. The data from the cross-sectional survey were summarized by using descriptive statistics, and the data were then analyzed by using the chi-square test of association and a multiple logistic regression model, while content thematic analysis was used to analyze the qualitative data. In the rural and urban areas, respectively, 39.7% and 52.2% had a positive perception of CVD risk. In the rural and urban areas, 44% and 41.6% of individuals respectively had moderate-to-high risk of CVD. Participants with at least secondary school education [2.66 (0.61-11.53)] and participants in the urban area [2.62 (0.78-7.08)] had twice higher odds of positive CVD risk perception. Males [3.91 (1.58-9.68)], adults aged 40 and above [1.59 (0.63-4.00)] and urban dwellers [1.21 (0.33-4.39)] had higher odds of a high CVD risk status. The qualitative aspect of the study corroborated the findings from the survey, as many participants did not perceive themselves as being at risk of CVD. The majority of the participants in this study were found to have a moderate-to-high risk of CVD, and many had a negative perception of their risk. Health education and CVD prevention programs are required to curb the burden of CVD.

Pattern and perception of wellbeing, quality of work life and quality of care of health professionals in Southwest Nigeria.

BACKGROUND: Personal wellbeing (PW) including quality of life and work life is a very complex concept that influences health professionals' commitment and productivity. Improving PW may result in positive outcomes and good quality of care. Therefore, this study aimed to assess the pattern and perception of wellbeing, quality of work life (QoWL) and quality of care (QoC) of health professionals (HPs) in southwest Nigeria.  METHODS: The study was a convergent parallel mixed method design comprising a cross-sectional survey (1580 conveniently selected participants) and a focus group interview (40 purposively selected participants). Participants' PW, quality of life (QoL), QoWL, and QoC were assessed using the PW Index Scale, 5-item World Health Organization Well-Being Index, QoWL questionnaire, and Clinician QoC scale, respectively. The pattern of wellbeing, QoWL and quality of care of HPs were evaluated using t-test and ANOVA tests. Binary regression analysis was used to assess factors that could classify participants as having good or poor wellbeing, QoWL, and quality of care of HPs. The qualitative findings were thematically analyzed following two independent transcriptions. An inductive approach to naming themes was used. Codes were assigned to the data and common codes were grouped into categories, leading to themes and subthemes. RESULTS: Of 1600 administered questionnaires, 1580 were returned, giving a 98.75% response rate. Only 45.3%, 43.9%, 39.8% and 38.4% of HP reported good PW, QoL, QoC and QoWL, respectively; while 54.7%, 56.1%, 60.2% and 61.6% were poor. There were significant gender differences in PW and QoC in favor of females. With an increase in age and years of practice, there was a significant increase in PW, QoWL and QoC. As the work volume increased, there was significant decrease in QoWL. Participants with master's or Ph.D. degrees reported improved QoWL while those with diploma reported better QoC. PWI and QoC were significantly different along the type of appointment, with those who held part-time appointments having the least values. The regression models showed that participant's characteristics such as age, gender, designation, and work volume significantly classified health professionals who had good or poor QoC, QoWL, PW and QoL. The focus group interview revealed four themes and 16 sub-themes. The four themes were the definitions of QoC, QoWL, and PW, and dimensions of QoC. CONCLUSION: More than half of health professionals reported poor quality of work life, quality of life and personal wellbeing which were influenced by personal and work-related factors. All these may have influenced the poor quality of care reported, despite the finding of a good knowledge of what quality of care entails.

Effects of a four-week aerobic exercise programme on depression, anxiety and general self-efficacy in people living with HIV on highly active anti-retroviral therapy.

The Human Immunodeficiency Virus (HIV) remains a major public health concern. Depression, anxiety and reduced self-efficacy are common psychological problems experienced by people living with HIV. We investigated the effects of a four-week, supervised aerobic exercise programme on depression, anxiety and self-efficacy of people living with HIV on HAART in Ibadan, Nigeria. A quasi-experimental design was used. Fifty-three eligible participants completed the study and only their data were analysed. The experimental subjects received aerobic exercise training for thirty minutes, three times per week for four weeks, alongside HAART, while control subjects were only on HAART. Depression, anxiety and self-efficacy scores were assessed at baseline and after the fourth week. Descriptive statistics of mean and standard deviation were used to summarise data, and inferential statistics of independent t-test was used to compare data between groups. At the end of the aerobic exercise programme, there was significant improvement in depression (p < 0.001), anxiety (p < 0.001) and self-efficacy scores (p = 0.042) in the experimental group, compared to the control group. More attention should be given to the prevention and management of psychological problems in people living with HIV through the use of aerobic exercise.

Correlation of sonographic and cytologic patterns of thyroid nodules.

INTRODUCTION: thyroid nodules are palpable in about 8% of adults. It is necessary to differentiate benign nodules from malignant ones by the non-invasive ultrasonography thereby reducing the frequency of the invasive fine needle aspiration cytology (FNAC). The study assessed the sonographic and FNAC patterns of thyroid nodules for benign and malignant features in a black African population. METHODS: this was a hospital-based, cross-sectional study design over a 1-year period in which one hundred and seven (107) consenting patients between 15 to 80 years of age with palpable thyroid masses by convenience sampling, were consecutively recruited to have both thyroid ultrasound scan and FNAC of their thyroid mass sequentially. Frequency, percentages and two-by-two contingency table were employed for data analysis. RESULTS: the sonographic features of the thyroid nodules varied from round 80 (74.8%) to oval 25 (23.4%) masses, the presence of thin peripheral halo 83 (77.6%), heterogeneous echo-pattern 104 (97.2%) with cystic component and peripheral vascularity 75 (70.1%). One hundred and five (98.1%) study participants showed benign features on sonography while two had features suspicious of malignancy; however FNAC result in the same group of patients was suggestive of benign masses in all 107 (100%) patients. Histology however confirmed malignancy in the 2 participants with ultrasound features suggestive of malignant thyroid nodules. CONCLUSION: ultrasonography is very sensitive in the characterization of thyroid nodules into benign or suspicious for malignancy in black African population.

Towards cardiovascular disease prevention in Nigeria: A mixed method study of how adolescents and young adults in a university setting perceive cardiovascular disease and risk factors.

BACKGROUND: Cardiovascular disease (CVD) is a global problem but its increasing prevalence in the working age group in developing countries like Nigeria is concerning and needs urgent attention. METHODS: The study was a mixed method design: quantitative phase with 402 participants and qualitative phase with 16 participants in two focus groups. The participants in the quantitative survey phase completed two questionnaires on the knowledge and perception of CVD and its risk factors. Data from the quantitative cross-sectional survey were analysed using descriptive and inferential statistics. The qualitative data were analysed using content thematic analysis. RESULTS: We report that 39.1% of the participants had high knowledge whilst 61.9% had low and average knowledge of CVD and its risk factors. Of the participants, 78.1% had a wrong perception of CVD and its risk factors. Participants from faculties of veterinary medicine and basic medical sciences had better knowledge than others who were not medically inclined (F = 16.11; p 0.001). Only participants from the faculty of veterinary medicine had the right perception of CVD and its risk factors. There was no significant difference in knowledge and perception scores between male and female participants. The qualitative study buttressed the results from the cross-sectional survey, where adolescents and young adults highlighted academic stress and poverty as major risk factors for CVD. CONCLUSION: Adolescents and young adults in this study did not have good knowledge of CVD and its risk factors. They also had a wrong perception about CVD and its risk factors.

Perspectives of Nigerian Athletes About Physiotherapy Services in Sports Injury Management: Implications for Rehabilitation.

BACKGROUND: Athletes' perceptions toward physiotherapy services have an impact on their general attitude toward these services and their willingness to work together with physiotherapists for rehabilitation. The study investigated athletes' perspectives of physiotherapy services in sports injury management. METHODS: A mixed-study design of a cross-sectional survey that involved 178 conveniently sampled athletes and an explanatory qualitative study (8 purposively-selected athletes) was used. The authors assessed the participants' knowledge and perception of physiotherapy services using the modified versions of the Athletes' Level of Knowledge Questionnaire, Matsuno Athletes Perception Scale, and focus group discussion. The data were analyzed using chi-square, Spearman correlation at P ≤ .05, and deductive reasoning thematic analysis. RESULTS: The age of the participants for the cross-sectional survey (131 men and 47 women) was 22.50 (7.51) years. Our results showed that the majority (91.6%) of them had adequate knowledge and (78.7%) positive perception about the role physiotherapists play in sports injury management. The participants' knowledge of physiotherapy services had a significantly positive correlation with age (ρ = .12; P = .01), sporting years (ρ = .17; P = .02), and duration in sports council (ρ = .19; P = .01), while their perception showed a negative correlation with age (ρ = -.15; P = .05), sporting years (ρ = -.16; P = .03), and duration in sports council (ρ = -.08; P = .02). However, no significant correlation existed between the participants' knowledge; perception and level of education; level of competition; type of sport; and type, nature, and severity of sport injury. Seven themes were generated from the focus group discussion. CONCLUSION: The participants reported adequate knowledge and a positive perception of physiotherapy services. The correlates of participants' knowledge and perception of physiotherapy services are age, sporting years, and duration in the sports council. From the qualitative component of the study, the authors identified the need to provide more physiotherapy services to athletes and more facilities for physiotherapy services.

Cross-cultural adaptation and validation of the Igbo language version of the stroke-specific quality of life scale 2.0.

INTRODUCTION: availability of the Stroke-Specific Quality of Life scale 2.0 (SS-QoL(E)) in Yoruba and Hausa, two of the three major indigenous languages in Nigeria have the potential to promote its uptake among these population, however, its non-availability in the Igbo languages makes its use restrictive among the south-eastern Nigerians. This study was aimed at cross-culturally adapting and assessing validity and reliability of the Igbo version of the SS-QoL. METHODS: the SS-QoL(E) was cross-culturally adapted to Igbo following the American Association of Orthopaedic Surgeons' guideline. This involved forward and back-translations, expert committee review, pretesting and cognitive debriefing interview to produce the final Igbo version, SS-QoL(I). The validity and reliability test involved 50 consenting Igbo stroke survivors. The construct validity was assessed by administering SS-QoL(E) and SS-QoL(I) on all 50 respondents, while SS-QoL(I) was re-administered at 7-day interval to assess test-retest reliability. Each scale was administered in random order. Data were analysed using Spearman's correlation, Wilcoxon's signed-rank test, Cronbach's alpha, Intra-class Correlation Coefficient (ICC), independent t-test and one-way ANOVA at p<0.05. RESULTS: respondents' domains scores on SS-QoL(E) and SS-QoL(I) did not differ significantly except in mobility and work (r=0.58 to 0.87; p=0.001). Cronbach's alpha was 0.69 to 0.87 for domains scores. The ICC ranged from 0.48 to 0.84, while no significant differences was found across different age groups or gender for the domains or overall scores of SS-QoL(I). CONCLUSION: the Igbo version of the SS-QoL has limited alterations from the original version and has moderate to excellent validity and reliability values.

Psychometric testing of Ibadan low back pain disability questionnaire.

BACKGROUND: The Ibadan Low Back Pain Disability Questionnaire (ILBPDQ) was developed to meet the need for a LBP treatment outcome measure that was appropriate for the Nigerian culture and environment. The objective of this study was to determine the psychometric properties of ILBPDQ. METHODS: This study used the validation design. One hundred and forty-two participants with LBP (LBPPs) and 142 age and sex-matched participants without LBP (NLBPPs) were included. The LBPPs were recruited consecutively from Physiotherapy clinics of selected tertiary hospitals in the six geopolitical zones of Nigeria. Both LBPPs and NLBPPs completed the ILBPDQ - the LBPPs completed the Numerical Pain Rating Scale (NPRS). The ILBPDQ was completed by 113 LBPPs two days after initial assessment. Sixty-four of the LBPPs received physiotherapy for 5-weeks, after which they were reassessed using ILBPDQ and NPRS. RESULTS: ILBPDQ score of LBPPs was significantly higher than that of NLBPPs (construct validity) and LBPPs NPRS score correlated significantly with their ILBPDQ score (r = 0.50) at baseline and post intervention (r =0.35) (divergent validity). ILBPDQ scores at baseline and 48 hours later for LBPPs correlated significantly (Intra Class Correlation =0.80) (test re -test reliability). Cronbach's α for ILBPDQ was 0.84 (internal consistency). The postintervention ILBPDQ and NPRS scores for LBPPs were significantly lower than their pre-intervention ILBPDQ scores (responsiveness) and NPRS scores. The changes in ILBPDQ and NPRS scores of the LBPPs correlated significantly (r =0.62) (responsiveness). CONCLUSION: The ILBPDQ demonstrated evidence of validity, reliability and responsiveness. FUNDING: University of Ibadan Senate Research Grant.

Development and structural validity of a Nigerian culture- and environment-friendly low back pain outcome measure: Ibadan Low Back Pain Disability Questionnaire.

BACKGROUND: Low Back Pain (LBP) is the leading cause of disability globally. Standardized outcome measures for measuring LBP disability exist but none was developed with consideration for the Nigerian culture and environment. OBJECTIVE: This study was aimed to develop a Nigerian culture- and environment-friendly LBP scale, the Ibadan Low Back Pain Disability Questionnaire (ILBPDQ). METHODS: Items on ILBPDQ were devised from literature review, interview of patients (231 consecutively-sampled patients with chronic non-specific LBP) and 12 professionals experienced in LBP management and were contentvalidated. The first draft of the questionnaire underwent pretesting twice among individuals with chronic non-specific LBP (n=35 and 114 respectively), factor analysis and experts' reviews to produce the final version. RESULTS: The final scale comprised 18 items with a two-factor structure (common Activity of Daily Living [ADL] and culture-specific ADL). It has eigen value ≥ 1 and explained 60% of variance. Items on ILBPDQ covered important constructs relevant to an average Nigerian patient with LBP. CONCLUSION: A scale for assessing disability in LBP is made available for use in Nigeria and similar populations. FUNDING: None declared.

Healthcare professionals' perception of quality of care of patients with cardiac disease in Nigeria: Implication for clinical guideline, inter-professional education and team work.

Background: Heart disease is one of the leading chronic conditions posing a major and growing threat to the public. Studies on quality of care given to patients with heart diseases in Nigeria are not available. The purpose of this study was to explore healthcare professionals' perception of quality of care of patients with heart disease at a tertiary hospital in Nigeria. Methods: A mixed method design was utilized in this study. Twenty eight healthcare professionals consisting of cardiologists, nurses, physiotherapists and dieticians were recruited into the study through purposive sampling technique. A questionnaire developed and validated from existing questionnaire was used to survey the health care professionals' perception of care and qualitative design was further used to explore their perceptions of care. The data were analyzed using descriptive statistics of percentages and graphs. The qualitative data were analyzed using thematic analysis. Quality of care was assessed through structure, process and outcome of care indices. Results: The mean age of the healthcare professionals was 38.46±8.988 years. 19 (66.7%) reported that there were treatment guidelines for cardiac disease management but there was no system for internal quality assurance. 18 (95%) out of these 19 healthcare professionals reported that the treatment guidelines were either never applied or not applied regularly during treatment. Other areas that were perceived as poor were poor teamwork, poor staff strength, inadequate equipment, and inadequate consultation with staff during procurement of medical supplies. Conclusion: Quality of care for cardiac patients in a Nigerian tertiary hospital was perceived as sub-optimal. There is a need for the improvement of the structure and process of quality of care to enhance quality of care for cardiac patients in Nigeria.

Factors influencing the use of outcome measures in knee osteoarthritis: A mixed method study of physiotherapists in Nigeria.

Background: Osteoarthritis (OA) of the knee constitutes a significant proportion of musculoskeletal disorders managed in physiotherapy clinics worldwide. Best practice guidelines in the management of OA ensure the use of outcome measures. Aim: This study explored the factors influencing the use of outcome measures in management of patients with knee OA among physiotherapists in southwestern Nigeria. Methods: Mixed method design was used that involved a cross-sectional survey of 77 purposively selected physiotherapists and a focus group discussion with another 6 physiotherapists. Results: Participants (48 males, 29 females) were aged 35.3 ± 7.3 years. Fifty-two (67.5%) participants reported the use of outcome measures in the treatment of the patients with knee OA. The perceived barriers reported were lack of time/heavy workload (55.9%); lack of standardization of outcome measures (45%); lack of motivation (36.4%); and nonavailability of outcome measures in the clinic (36.4%). Reported perceived facilitators include interest/need to track patient's progress and ethical practice (87.1%); familiarity with outcome measures (87.0%); and understanding of the benefits of using outcome measures (87.0%). Conclusion: There is a need to establish good organizational structure focusing on the use of outcome measures in practice and development of a concessional toolkit of short and easily applicable instruments with user description.

Interprofessional education among Nigerian clinical students: implications for interprofessional care.

Interprofessional education (IPE) is effective for teaching health profession students about the roles of different healthcare professionals for collaborative practice. This study was designed to investigate clinical students' awareness, knowledge, and perception of IPE. A mixed method convergent parallel design of Cross-Sectional Survey (CSS) and Focus Group Discussion (FGD) was used. Data on awareness, perception and knowledge about IPE were collected using a self-developed, content-validated questionnaire and Readiness for Interprofessional Learning Scale, respectively, and was analysed using Chi-Square, and Mann-Whitney U test at α = 0.05. For the FGD, data were collected from 13 purposively selected students in a Nigerian university and analysed through content thematic analysis. Participants in the CSS were aged 21.9 ± 2.0 years. Over half of the participants (57.4%) reported being unaware of IPE. More than half (73.0%) of the participants that were aware had good knowledge. Majority (93.3%) had a positive perception of IPE. There was a significant association between participants' knowledge and perception (p = 0.008) of IPE; however, there was no significant association (p = 0.051) between their awareness and perception. Also, there were no significant sex variations in the knowledge of IPE (0.371). However, there was a significant sex difference in their perception (p = 0.008). Some of the discussants in the FGD reported being aware of the term IPE. Discussants had at least fair knowledge of IPE and reported that IPE is important; and supports its formal implementation and inclusion in the curricula of study; emphasizing that it should be started early enough in their training. Awareness of interprofessional education is sub-optimal among these clinical students, however more than half of those who were aware had good knowledge. Most of them had a positive perception. There is a need to improve clinical students' awareness and knowledge about IPE by using integrated seminars and implementing IPE into the curricula of their training.

Cross-cultural adaptation, content validation, and reliability of the Nigerian Composite Lifestyle CVD Risk Factors Questionnaire for adolescents among Yoruba rural adolescents in Nigeria.

BACKGROUND: Assessment of lifestyle risk factors must be culturally- and contextually relevant and available in local languages. This paper reports on a study which aimed to cross culturally adapt a composite lifestyle cardiovascular disease (CVD) risk factors questionnaire into an African language (Yoruba) and testing some of its psychometric properties such as content validity and test retest reliability in comparison to the original English version. METHODS: This study utilized a cross sectional design. Translation of the English version of the questionnaire into Yoruba was undertaken using the guideline by Beaton et al. The translated instrument was presented to 21 rural adolescents to assess comprehensibility and clarity using a sample of convenience. A test retest reliability was conducted among 150 rural adolescents using a purposive sampling. Data was analyzed using intraclass correlation (ICC ) model 3, Cohen kappa statistics and prevalence rates. RESULTS: ICC ranged between 0.4-0.8. The Yoruba version was completed 15-20 minutes and was reported to be culturally appropriate and acceptable for rural Nigerian adolescents. CONCLUSIONS: The Yoruba translation of the Nigerian composite lifestyle risk factors questionnaire performs at least as well as the original English version in terms of content validity and reliability. It took a shorter time to complete therefore may be more relevant to rural adolescents.

Are lifestyle cardiovascular disease risk factors associated with pre-hypertension in 15-18 years rural Nigerian youth? A cross sectional study.

BACKGROUND: Cardiovascular disease (CVD) is a public health concern worldwide. Hypertensive heart disease is predominant in Nigeria. To effectively reduce CVD in Nigeria, the prevalence of, and factors associated with, pre-hypertension in Nigerian youth first need to be established. METHODS: A locally-validated CVD risk factor survey was completed by 15-18 year olds in a rural setting in south-west Nigeria. Body Mass Index (BMI), waist-hip ratio and systolic and diastolic blood pressure was measured. Putative risk factors were tested in gender-specific hypothesized causal pathways for overweight/obesity, and for pre-hypertension. RESULTS: Of 1079 participants, prevalence of systolic pre-hypertension was 33.2 %, diastolic pre-hypertension prevalence approximated 5 %, and hypertension occurred in less than 10 % sample. There were no gender differences in prevalence of pre- hypertension, and significant predictors of systolic pre-hypertension (high BMI and older age) were identified. Considering high BMI, older age was a risk for both genders, whilst fried food preference was female-only risk, and low breakfast cereal intake was a male-only risk. CONCLUSION: Rural Nigerian adolescents are at-risk of future CVD because of lifestyle factors, and high prevalence of systolic pre-hypertension. Relevant interventions can now be proposed to reduce BMI and thus ameliorate future rural adult Nigerian CVD.

High prevalence and clustering of modifiable CVD risk factors among rural adolescents in southwest Nigeria: implication for grass root prevention.

BACKGROUND: Cardiovascular disease (CVD) is an immense global problem with serious economic and social consequences. Modifiable risk factors for CVD have been identified internationally in adolescents where early intervention programs have the potential to reduce CVD risk on individual and population levels. In developing countries such as Nigeria, little is known about the prevalence of modifiable CVD risk factors among adolescents especially in the rural areas. METHODS: This paper reports on a cross-sectional survey of modifiable CVD risk factors among rural adolescents in South-West Nigeria. All 15-18 years old adolescents in all the schools at Ibarapa central local government were approached and all those who assented and consented to participate in the study were involved. A total of 1500 adolescents participated in the study. Measurements of CVD risks factors taken were; smoking, physical activity, alcohol, dietary pattern using a questionnaire developed by authors. Other CVD risk factors such as waist hip ratio and BMI were taken using standardized instruments. Data were analyzed using STATA version 12. RESULTS: Data from 1079 adolescents (56.5% males and 53.5% females) were analyzed. Mean age of males was 16.4 ± 1.14 years and mean age for females was 16.29 ± 1.13 years. Adolescents showed clustering of CVD risk factors with about 72% having between two and four risk factors. A total of 102 clustering patterns were reported. The most common clustering pattern (19.6%) included high animal lipid and salt diet. CONCLUSION: There is high level and clustering of CVD risk factors among rural adolescents in Southwest Nigeria. The most common clustering pattern was biased towards dietary factors. The high prevalence of CVD risk factors among rural adolescents in Southwest Nigeria suggests that urgent primary prevention programs are required to prevent the next generation of Nigerians from suffering of CVD.

A systematic review and appraisal of methods of developing and validating lifestyle cardiovascular disease risk factors questionnaires.

BACKGROUND: Well developed and validated lifestyle cardiovascular disease (CVD) risk factors questionnaires is the key to obtaining accurate information to enable planning of CVD prevention program which is a necessity in developing countries. We conducted this review to assess methods and processes used for development and content validation of lifestyle CVD risk factors questionnaires and possibly develop an evidence based guideline for development and content validation of lifestyle CVD risk factors questionnaires. MATERIALS/METHODS: Relevant databases at the Stellenbosch University library were searched for studies conducted between 2008 and 2012, in English language and among humans. Using the following databases; pubmed, cinahl, psyc info and proquest. Search terms used were CVD risk factors, questionnaires, smoking, alcohol, physical activity and diet. RESULTS: Methods identified for development of lifestyle CVD risk factors were; review of literature either systematic or traditional, involvement of expert and /or target population using focus group discussion/interview, clinical experience of authors and deductive reasoning of authors. For validation, methods used were; the involvement of expert panel, the use of target population and factor analysis. CONCLUSION: Combination of methods produces questionnaires with good content validity and other psychometric properties which we consider good.

Catastrophising, pain, and disability in patients with nonspecific low back pain.

BACKGROUND: Attention has been drawn to examining the contributions of "catastrophising" to the prediction of pain and disability in individuals with low back pain (LBP). OBJECTIVES: This study investigated the proportion of patients with LBP who engaged in catastrophic thinking about pain and its association with pain intensity and disability. We also investigated the components of pain catastrophising that is predictive of disability. METHODS: A total of 275 participants with nonspecific LBP completed the Pain Catastrophizing Scale, the quadruple visual analog scale, and the Revised Oswestry Disability Questionnaire (RODQ). The associations among pain intensity, disability, and catastrophising were investigated using t test. The components of catastrophising that best predicts disability were investigated using multiple linear regressions, and the level of significance was set at 0.05. RESULTS: The majority (85.5%) of the participants had LBP for more than 6 weeks, with 45.5% of the participants having moderate disability and 52.7% being high catastrophisers. High catastrophisers to pain had a significantly higher rating of pain intensity (p < 0.001) and higher score on the RODQ than low catastrophisers to pain. The main components of catastrophising that predicts disability were magnification (p < 0.001) and rumination (p = 0.006). CONCLUSION: Clinicians should screen patients with nonspecific LBP for a heightened level of catastrophic thinking and endeavour to manage such when present.

Development, initial content validation and reliability of Nigerian composite lifestyle CVD risk factors questionnaire for adolescents.

BACKGROUND: Cardiovascular disease risk (CVD) factors affect every age category including adolescents in developing nations. Prevention strategies are effective only when there are epidemiological data for the targeted populations. The collection of such data is only made easy with composite lifestyle CVD risk factors measures that are culturally sensitive and acceptable among the target populations. OBJECTIVE: The objective of the study was to develop a culturally sensitive and friendly composite lifestyle CVD risk factors questionnaire for adolescents in Nigeria. METHODS: A systematic review was conducted to identify existing, published questionnaires from which items could be selected. Content and face validation were conducted using an expert panel and a sub-sample of the target population. Data was analyzed qualitatively and reliability was assessed using intra-class correlation and Kappa statistic. RESULTS: Based on the comments received from experts, the questions were restructured, simplified, clarified, formatted, some questions were added and expert reached a consensus. Kappa showed fair to moderate agreement in 65% of the questions and perfect agreement in one question. CONCLUSION: The CVD risk factors questionnaire has acceptable content validity and reliability and should be used to assess CVD risk factors among adolescents in Nigeria.
