Introduction: diabetes mellitus (DM) and Obstructive Sleep Apnea (OSA) are two major and interconnected non-communicable diseases. Both negatively impact on sleep quality. This study aimed to determine among persons with type 2 DM, the proportions at high risk of OSA and of self-reported poor sleep quality along with their associated-factors in Parakou city, Benin. Methods: this was a cross-sectional prospective study of 100% (n=383) outpatient adults with type 2 DM, conducted between April and August 2019 in the three top centres managing diabetic persons in Parakou city. They were interviewed, examined and investigated using capillary fasting blood glucose tests. The STOP-Bang Questionnaire (SBQ) was used to determine the risk of OSA. Results: overall, their mean age was 57.37 (11.45) years. They were 61.62% (n=236) females and 38.38% (n=147) males. Sleep duration was insufficient in 26.89% (n=103). Nocturia was reported in 49.35% (n=189). The risk of OSA was high in 14.10% (n=54), intermediate in 24.80% (n=95) and low in 61.10% (n=234). Friedman Position Tongue Grade 3 (Adjusted Odds Ratio, aOR=2.48; 95%CI=1.11 - 5.55; p=0.025) and 4 (aOR=4.65; 95%CI=1.26 - 15.90; p=0.015) were independently associated with a high risk of OSA. The prevalence of reported poor sleep quality was 27.42% (n=105). Female gender (aOR=2.08; 95%CI=1.18-3.83; p=0.014), diabetic foot (aOR=5.07; 95%CI=1.15-23.63; p=0.031), nocturia (aOR=1.96; 95%CI=1.18-3.29; p=0.010), tiredness (aOR=2.77; 95%CI=1.26-6.23; p=0.012) and a high risk of OSA (aOR=3.31; 95%CI=1.28-8.93; p=0.015) were independently associated with a greater risk of reported poor sleep quality. Conclusion: in Parakou, the proportions of patients with type 2 DM at increased risk of OSA and with poor quality of sleep are relatively high. There is need for better systematic screening of OSA in persons with DM. [ABSTRACT FROM AUTHOR]

Background: In the "Centre National Hospitalier de Pneumo-Phtisiologie" of Cotonou, Benin, little is known about the characteristics of patients who have not attended their scheduled appointment, the results of tracing and the possible benefits on improving treatment outcomes. This study aimed to determine the contribution of tracing activities for those who missed scheduled appointments towards a successful treatment outcome.Methods: A retrospective cohort study was carried out among all smear-positive pulmonary tuberculosis patients treated between January and September 2013. Data on demographic and diagnostic characteristics and treatment outcomes were accessed from tuberculosis registers and treatment cards. Information on those who missed their scheduled appointments was collected from the tracing tuberculosis register. A univariate analysis was performed to explore factors associated with missing a scheduled appointment.Results: Of 457 patients (410 new smear-positive and 47 retreatment tuberculosis), 37 (8%) missed one or more of their appointments with a total of 44 episodes of missed appointments. The 3.5th (32%) and 5th (43%) month appointments were the ones most likely to be missed. Being male was associated with a higher risk of missing appointments (RR = 4.2; 95% CI = 1.5-11.8, p = 0.004) while having HIV infection was associated with a lower risk (RR = 0.3, 95% CI = 0.1-0.9, p = 0.03). Principal reasons for missed appointments were travelling outside Cotonou (34%) and feeling better (21%). In 24 (55%) of these 44 episodes of missed appointments, contact was made with the patient who returned to the programme. These follow-up activities increased the treatment success by 4%.Conclusion: In Cotonou, Benin, less than 10% of tuberculosis patients miss at least one of their scheduled appointments. Tracing activities increase the treatment success rate by 4% and current on-going practices in the Programme need to be endorsed and encouraged. [ABSTRACT FROM AUTHOR]
