10-Year Risk of Developing Type 2 Diabetes Mellitus: A Survey of Rural Communities in Southern Nigeria.

BACKGROUND: The exponential rise in the prevalence of Type 2 Diabetes (T2DM) necessitates the introduction of strategies for early diagnosis to reduce the burden of the disease. This study assessed the prevalence of prediabetes and also determined the 10-year risk of developing T2DM in Southern Nigerian rural communities by adopting the validated Finnish Diabetes Risk Score (FINDRISC) tool. METHODS: 273 participants from 3 Southern rural communities aged 18 years and older were recruited in this cross-sectional study. Data in the FINDRISC stratification tool and Random Blood Glucose (RBG) variables were obtained for the participants. IBM SPSS version 21 was used to analyze the data with a level of significance put at p < 0.05. RESULTS: The participants' mean age was 54.20±16.61 years. The prevalence of prediabetes among the study participants based on RBG was 4.8% (3.8% of males and 6.6% of females, respectively). Most of the study participants (41%) had a low risk of developing T2DM which meant that 1 in 100 participants would become diabetic in a 10-year period, based on the FINDRISC scale. Amongst the male participants, the Total Diabetes Risk Score (TDRS) showed significant positive correlation with the RBG (r=0.315, p=0.001); similarly, a weak positive correlation between TDRS and RBG was noted among female participants. CONCLUSION: The propensity of developing T2DM in 10 years was indisputably low amongst rural dwellers in the Southern Nigerian rural communities studied. Further studies to compare the risk of developing T2DM between rural and urban communities would be required.

CONTEXTE: L'augmentation exponentielle de la prévalence du diabète de type 2 (DT2) nécessite l'introduction de stratégies de diagnostic précoce pour réduire le fardeau de la maladie. Cette étude évalue la prévalence du prédiabète et détermine également le risque sur 10 ans de développer un DT2 dans les communautés rurales du sud du Nigeria en adoptant l'outil validé FINDRISC (Finnish Diabetes Risk Score). MÉTHODES: 273 participants de 3 communautés rurales du sud du pays âgés de 18 ans et plus ont été recrutés dans cette étude transversale. Les données de l'outil de stratification FINDRISC et les variables de la glycémie aléatoire (RBG) ont été obtenues pour les participants. IBM SPSS version 21 a été utilisé pour analyser les données avec un niveau de signification mis à p < 0,05. RÉSULTATS: L'âge moyen des participants était de 54,20±16,61 ans. La prévalence du prédiabète parmi les participants à l'étude, basée sur le RBG, était de 4,8% (3,8% des hommes et 6,6% des femmes respectivement). La plupart des participants à l'étude (41%) présentaient un faible risque de développer un DT2, ce qui signifie que 1 participant sur 100 deviendrait diabétique sur une période de 10 ans, selon l'échelle FINDRISC. Chez les hommes, le score total de risque de diabète (TDRS) a montré une corrélation positive significative avec le RBG (r=0,315, p=0,001) ; de même, une faible corrélation positive entre le TDRS et le RBG a été notée chez les femmes. CONCLUSION: La propension à développer un DT2 en 10 ans est indiscutablement faible chez les habitants des communautés rurales du sud du Nigeria étudiées. D'autres études visant à comparer le risque de développer un DT2 entre les communautés rurales et urbaines seraient nécessaires.

Determinants of Asymptomatic Bacteriuria in HIV-positive and Negative Pregnant Women in Sagamu, South-West Nigeria.

BACKGROUND: Pregnant women with asymptomatic bacteriuria are at increased risk of developing symptomatic urinary tract infections. HIV infection may modify the acquisition of bacteriuria in pregnancy. OBJECTIVE: To identify the determinants of asymptomatic bacteriuria in HIV-positive and HIV-negative pregnant women in Olabisi Onabanjo University Teaching Hospital, Sagamu, Nigeria. METHODS: A cross-sectional study involving 211 HIV-positive pregnant women and 422 HIV-negative pregnant women attending their first antenatal clinic between October 2017 and March 2018. Information on socio-demographic characteristics and risk factors for asymptomatic bacteriuria in study participants was recorded. Microbial culture was carried out on aseptically collected urine samples. RESULTS: Asymptomatic bacteriuria was found in 66(31.3%) and 118(28.0%) in HIV-positive and negative women respectively. Advanced maternal age, gestational age above 20 weeks, low socioeconomic status, history of urinary tract infections in previous pregnancies and low CD4 cell count had statistically significant association with increased prevalence of asymptomatic bacteriuria among HIV positive women. Binary logistic regression analysis showed that low socioeconomic status and history of urinary tract infections in previous pregnancies were strong determinants of asymptomatic bacteriuria among HIV positive women (AOR 4.1, CI 1.9-8.7, P < 0.001; AOR 5.8, CI 2.5-13.6, P < 0.001 respectively). In HIV negative women, gestational age above 20 weeks had statistically significant association with increased prevalence of asymptomatic bacteriuria (AOR= 2.34, CI 1.3-4.1, P= 0.002). CONCLUSION: Low socioeconomic status and previous history of urinary tract infections are determinants of asymptomatic bacteriuria in HIV positive women while gestational age above 20 weeks is a determinant in HIV negative women. These determinants could be used to identify women at high risk of asymptomatic bacteriuria for targeted screening.

Placenta Praevia: A Retrospective Review of Experience at Olabisi Onabanjo University Teaching Hospital, Sagamu.

BACKGROUND: Placenta praevia is the most common cause of antepartum haemorrhage. It is a potentially life threatening condition associated with morbidity and mortality. There is no study on the pattern and management of placenta praevia in Sagamu. AIM AND OBJECTIVES: To determine the risk factors, pattern of presentation and management outcome of pregnancies complicated by placenta praevia. DESIGN: This was a five-year retrospective study Setting: Olabisi Onabanjo University Teaching Hospital, Sagamu, Ogun State, Nigeria. MATERIALS AND METHODS: Relevant information was retrieved from the case notes of all patients who presented with placenta praevia from 1st January, 2013 to 31st December, 2017. The data were analyzed by using SPSS version 21. RESULTS: Out of the 5124 deliveries, there were 47 cases of placenta praevia giving a prevalence of 0.92%. Twenty-one subjects (50%) were within 31-40 years age group. The modal parity was 1. Twenty women (47.6%) had parity of 1-2. Thirty subjects (71.4%) were unbooked. Painless vaginal bleeding was the commonest mode of presentation in 30(73.8%) women while Type III was the commonest grade 15(35.7%). Nineteen subjects (45.2%) had no identifiable risk factors. Postpartum haemorrage was the most common complication (23.8%). There was no maternal death while the perinatal mortality was 13.5%. There was no significant association between booking status, type of placenta praevia, mode of delivery, blood loss at delivery, and the one minute APGAR score. CONCLUSION: The prevalence of placenta praevia in Olabisi Onabanjo University Teaching Hospital is comparable with other tertiary facilities in Nigeria. Upgrading comprehensive emergency obstetric services, improving neonatal services and a multidisciplinary approach to management of all cases will ensure good outcome for the mother and baby.
