Prevalence of overweight and obesity in Nigeria: Systematic review and meta-analysis of population-based studies.

In Nigeria, several studies have assessed the prevalence of overweight/obesity with different reports. The purpose of this study was to use a systematic review and meta-analysis to analyze these overweight and obesity reports from different locations in Nigeria over the last ten years. In addition, there was a dearth of systematic reviews and meta-analyses on the prevalence, trends, and demographic characteristics of overweight and obesity in the country. This was a systematic review and meta-analysis of cross-sectional population-based studies among adult Nigerians on the prevalence of overweight/ obesity (defined by body mass index) published from January 2010 to December 2020. Relevant abstracts were scrutinized and articles that included adults of all age groups and were not restricted to a particular group of people (e.g. university community) were selected. Each article was scrutinized by more than 2 authors before selection. The prevalence of overweight/obesity among all participants, among men and among women in Nigeria and its 6 geopolitical zones was determined. All analyses were performed using STATA version 14 (Stata Corp. College Station, Texas, USA). Thirty-three studies were selected and the number of participants was 37,205. The estimated prevalence of overweight and obesity was 27.6%, and 14.5% respectively. The prevalence of overweight among men and among women was 26.3% and 28.3% respectively and, the prevalence of obesity among men and women was 10.9% and 23.0% respectively. The prevalence of overweight in the 6 geopolitical zones was Southeast 29.3%, Southwest 29.3%, South-south 27.9%, Northwest 27.2%, North-central 25.3%, Northeast 20.0% and obesity South-south 24.7%, Southeast 15.7%, Southwest 13.9%, Northwest 10.4%, North-central 10.2%, Northeast 6.4%. Egger's tests showed no statistically significant publication bias among the studies that reported the overweight and obesity prevalence respectively (p = 0.225, P 0.350). The prevalence of overweight/obesity in Nigeria is high. The southern geopolitical zones had a higher prevalence of overweight/obesity.

Patient-Doctor relationship in underserved environment: A cross-sectional study of attitudinal orientation, practice inclination, barriers and benefits among medical practitioners in Abia State, Nigeria.

BACKGROUND: Healthcare has become complex requiring balance of ever-increasing demands on physicians against humanness of medicine. As the impetus for the delivery of patient-centred care grows, there is need to study the attitude and practice orientations of medical practitioners to patient-doctor relationship (PDR). The study was aimed at describing the attitude, practice, barriers and benefits of PDR among medical practitioners in Abia State. PARTICIPANTS AND METHODS: A descriptive cross-sectional study was carried out on 210 medical practitioners in Abia State who were consecutively recruited for the study. Data were collected using self-administered questionnaire that elicited information on attitude, practice, barriers and benefits of PDR. Attitude was assessed with the 18-item Patient-Practitioner Orientation Scale (PPOS) with subscales of caring and sharing. RESULTS: The age of the participants ranged from 26 to 77 years with the mean of 36 ± 8.4 years. There were 173 (82.4%) male. The caring attitude score (mean = 3.57 ± 0.80) was higher than sharing (mean = 3.42 ± 0.65) (P = 0.036). Practice was predominantly doctor-centred (86.7%) than patient-centred (64.3%, P < 0.0001). The most common barrier to PDR was patient-doctor communication, while the most common benefit of PDR was improvement in patient satisfaction. Medical practitioners with duration of practice <10 years had significantly higher mean scores in attitudinal subscale of caring when compared with those with duration of practice ≥10 years (P < 0.0001). The study participants with duration of practice ≥10 years had significantly higher adequate practice (75.0%) of patient-centred care when compared with their counterparts with duration of practice <10 years (47.6%) (P = 0.00005). CONCLUSION: The attitude to caring did not translate to comparative disposition to sharing. The practice was more doctor-centred than patient-centred. The most common barrier and benefit of PDR were communication drawbacks and improvement in patient satisfaction, respectively. Duration of practice was associated with caring attitude and practice of patient-centred care, respectively.

Mentoring in a resource-constrained context: A single-institutional cross-sectional study of the prevalence, benefits, barriers and predictors among post-graduate medical college fellows and members in South-Eastern Nigeria.

BACKGROUND: Globally, the post-graduate medical education has undergone tremendous changes with emphasis on training, services and research to equip trainees with competence for independent professional development. However, not all the fellows and members of the West African Post-graduate Medical College and the National Post-graduate Medical College of Nigeria recognise the values of mentoring in achieving the career success. AIM: The study was aimed at describing the prevalence, benefits, barriers and predictors of mentoring in a cross-section of the Post-graduate Medical College fellows and members in a tertiary health institution in South-Eastern Nigeria. PARTICIPANTS AND METHODS: A cross-sectional study was carried out among 168 study participants who were sampled from the Post-graduate Medical College fellows and members in the Federal Medical Centre, Umuahia, Nigeria. Data collection was done using a pre-tested, self-administered questionnaire that elicited information on awareness, prevalence, barriers and benefits of mentoring. RESULTS: The age of participants ranged from 26 to 59 (41 ± 9.4) years. All the respondents were aware of the mentorship. The prevalence of mentoring was 33.3%. The most common benefit was personal and professional growth and development (100.0%). The most common barrier was the pressure of professional duties and personal exigencies (100.0%). The most significant predictor of mentoring had departmental mentoring programme participants who had departmental mentoring programmes were two times more likely to have mentoring relationships when compared to their counterparts who had none (adjusted odds ratio = 2.32; 95% confidence interval: 1.20-3.10; P = 0.002). CONCLUSION: The level of awareness of mentoring was very high but did not translate to appropriate involvement in mentoring. The most common benefit was personal and professional growth and development. The most common barrier was the pressure of professional duties and personal exigencies. The most significant predictor of mentoring relationship had departmental mentoring programme.

Depression among ambulatory adult patients in a primary care clinic in southeastern Nigeria.

BACKGROUND: Depression is a global health problem that occupies eminent position in clinical and community mental health. As the global prevalence of depression increases, the sociomedical challenges associated with it increase, especially in resource-constrained environment. AIM: The study was aimed at describing depression among ambulatory adult patients in a primary care clinic in Southeastern Nigeria. PATIENTS AND METHODS: A cross-sectional descriptive hospital-based study was carried out on 400 adult patients in a primary care clinic of Federal Medical Centre, Umuahia. Data on relevant epidemiological variables were collected using pre-tested, structured interviewer-administered questionnaire. Patient Health Questionnaire-9 was used to assess for depression. Data were analysed using the Statistical Package for the Social Sciences software version 21. Test of associations was done using Chi-test and logistic regression, and P < 0.05 was considered statistically significant. RESULTS: The age of the study participants ranged from 18 to 78 years with mean age of 38 ± 9.2 years, and there were 40.5% males. The prevalence of depression was 48.5% with the most common type being mild depression (32.3%). Occurrences of symptoms were most frequent and severe in the home environment (59.8%) and during the night (62.9%). Hypertension (35.5%) and alcohol use (57.5%) were the most common medical condition and substance used, respectively. Depression was significantly associated with elderly age (P = 0.005), females (P = 0.017), physical inactivity (P = 0.039) and psychosocial stressors (P = 0.042). The most significant predictor of depression was elderly age (adjusted odds ratio = 2.50; 95% confidence interval [1.40-3.78]; P = 0.001). Older persons were three and half times more likely to have depression when compared to their counterparts who were younger. CONCLUSION: This study has demonstrated high prevalence of depression and some epidemiological factors in the occurrence of depression among the study participants. Depression occurred predominantly among the elderly, females, physically inactive, hypertensive and those who had psychosocial stressors. Occurrences of symptoms were most frequent at home and nighttime. The most commonly used substance was alcohol.

Prevalence of chronic kidney disease in Nigeria: systematic review of population-based studies.

BACKGROUND: The aim of this study was to identify and discuss published population-based studies carried out in Nigeria that have information on the prevalence of chronic kidney disease (CKD) and have also used the Kidney Disease Outcomes Quality Initiative (KDOQI) practice guidelines in defining CKD, with emphasis on the performance of three estimating equations for glomerular filtration rate (GFR) - Modification of Diet in Renal Disease (MDRD), Cock-croft-Gault, and CKD epidemiology collaboration (CKD-EPI) creatinine equation. MATERIALS AND METHODS: A systematic literature search was carried out in Google, MEDLINE, PubMed, and AJOL database, with the aim of identifying relevant population-based studies with information on the prevalence of CKD in a location in Nigeria. RESULTS: Seven cross-sectional population-based studies were identified. Two of the studies used the Cockcroft-Gault and observed a prevalence of 24.4% and 26%. Four of the studies used the MDRD and the prevalences observed were 12.3%, 14.2%, 2.5%, and 13.4%. One of the studies used the CKD-EPI equation and the prevalence was 11.4%. The male to female ratios of CKD prevalence in six studies were 1:1.9, 0.8:1, 1:1.6, 1:2, 1:1.8, 1:1.4, and the observed risk factors in the studies were old age, obesity, diabetes mellitus, hypertension, family history of hypertension, family history of renal disease, low-income occupation, use of traditional medication, low hemoglobin, and abdominal obesity. CONCLUSION: The prevalence of CKD was high but variable in Nigeria, influenced by the equation used to estimate the GFR. MDRD and CKD-EPI results are agreeable. There is a need for more population-based studies, with emphasis on repeating the GFR estimation after 3 months in subjects with GFR <60 mL/min/1.7 m2.
