Risk of obstructive sleep apnea and quality of sleep among adults with type 2 diabetes mellitus in a sub-Saharan Africa city.

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.

Fréquence et déterminants de la dénutrition post-opératoire en chirurgie viscérale au Centre National Hospitalier et Universitaire Koutoucou Hubert Maga, Cotonou: Frequency and determinants of post-operative undernutrition in patients undergoing visceral surgery at the University Hospital Centre Koutoucou Hubert Maga, Cotonou.

This study aims to determine the frequency and identify the factors associated with undernutrition among patients undergoing visceral surgery in 2014. We conducted a cross-sectional, descriptive and analytical study over the period September 11, 2014-December 11, 2014. The study population comprised patients who had undergone visceral surgery at the National University Hospital Centre Koutoucou Hubert MAGA, Cotonou. Undernutrition is defined as a body mass index less than 18.5 kg/m2. A total of 90 patients were included in the study, 57,78% (52 patients) were male. The average age of patients was 55±6,32 years. Undernutrition was found in 42 patients (46.67%). The factors associated with undernutrition in postoperative patients were: age greater than or equal to 50 years, low level of protein, water and energy intake, diarrhea, cancer, digestive system surgery, emergency surgery, significant weight loss and hyperleukocytosis. Undernutrition is common in postoperative patients. Hence the importance of nutritional screening and of early treatment.
