Prevalence of the metabolic syndrome and its components in secondary school student population in the city of Douala, Cameroon.

While the burden of metabolic syndrome (MetS) is still increasing in sub-Saharan Africa, there is a lack of data among young Cameroonian population. The aim of this study was to evaluate the prevalence of MetS and its components among secondary school students in Douala. This was a cross-sectional prospective study carried out on 803 students recruited from February to May 2021 in public and private secondary schools in Douala city, Cameroon. MetS was assessed according to the IDF/AHA/NHLBI 2009 consensus definition. The data collection consisted of a questionnaire on sociodemographic characteristics, measurement of anthropometric parameters (height, weight, body mass index (BMI), waist circumference) and overnight fasting blood sample. Blood pressure (BP), fasting blood glucose, HDL cholesterol and triglycerides were measured using standard methods. The mean age was 18±3 years, 73.3% female. The prevalence of MetS was 27.4%, common among participants aged ≥16 years, and higher in females compare to males (33.7% vs. 11.1%, P#x003C;0.0001). The prevalence of MetS components i.e abdominal obesity, high BP, fasting hyperglycemia, low-level HDL cholesterol and hypertriglyceridemia were 14.1, 18.1, 42.8, 51.4 and 38.6% respectively. All MetS components were significantly higher in females compared to males except for high BP which was similar among the genders. In our study population, the prevalence of MetS is high and this calls for improved monitoring to limit the evolution of associated cardiometabolic complications among young Cameroonians.

Burnout syndrome among healthcare professionals in the Fako division, Cameroon: Impact of physical activity and sleep quality.

Objectives: Burnout syndrome (BOS) is an affection mostly resulting from chronic job-related stress. Many studies have identified job-related and non-job-related factors associated with BOS. Our aim of this study was to assess the level of BOS in private and public hospital healthcare providers in Fako division, Cameroon and evaluate the impact of physical activity and sleep quality (SQ). Methods: The study was carried out in five randomly selected hospitals in Fako Division over a three-month period. Consenting doctors, nurses and laboratory technicians were recruited using consecutive sampling methods. Sociodemographic and professional characteristics were collected using a structured questionnaire. BOS was assessed using the Maslach Burnout Inventory Human Services Survey (MBI-HSS). Sleep quality (SQ) and physical activity (PA) were assessed using the Pittsburgh Sleep Quality Index (PSQI) and Global Physical Activity Questionnaire (GPAQ) respectively. Odd ratios and 95% confidence intervals were calculated and a statistical significance was set for p-value < 0.05. Results: The mean age was 32 ± 6 years and 70.9% female. BOS prevalence was 66.3% with 71.4% in females and 53.9% in males (p = 0.002). Of the 232 participants with BOS, 65.7%, 52% and 53.7% had moderate to high emotional exhaustion, depersonalization and decreased personal accomplishment, respectively. Moderate to high PA as well as poor SQ were not significantly associated with BOS while longer sleep duration (>8 h) was associated with a greater odd of BOS. Conclusions: The prevalence of BOS was high among healthcare professionals. While PA showed no protective effects, high sleep duration could increase its risk.

Musculoskeletal disorders and risk factors among heavy load carriers in Yaounde city, Cameroon.

Objectives. This study assessed musculoskeletal disorders (MSDs) and their correlates among heavy load carriers in Yaounde city, Cameroon. Methods. A descriptive cross-sectional study was conducted on 301 healthy male handlers. Descriptive statistics were used to determine prevalence while logistic regression was performed to determine associated factors. Results. MSD prevalence was 100 and 87.7% during the last 12 months and 7 days, respectively. Main sites affected were, respectively, the lower back (84.1 and 61.1%), hips/thighs (81.1 and 47.2%) and neck (74.7 and 43.2%). MSD risk factors were age 25-30 years during the last 12 months (odds ratio [OR] = 2.8; 95% confidence interval [CI] [-1.2, 6.5]) and 7 days (OR = 4.2; 95% CI [-1.7, 10.7]) for the neck and the last 12 months (OR = 2.6; 95% CI [-1.1, 5.8]) for shoulders. Overweight was a risk factor for wrists/hands in the last 12 months (OR = 2.7; 95% CI [-11.0, 7.2]). Seniority of 5-10 years was a risk factor for the lower back (OR = 1.8; 95% CI [-1.0, 3.3]) and hips/thighs (OR = 3.2; 95% CI [-1.7, 5.8]) in the last 7 days. Conclusion. Handlers showed high MSD prevalence in most sites, e.g., lower back, upper back, hips/thighs, shoulders and neck. Associated significant factors were age, overweight and seniority.

Effect of a 12-week training program on the anthropometric and physiological profiles of some participants registered in a fitness center in Douala, Cameroon.

Fitness centers are remarkably abundant in Cameroon. The aim of this work was to assess the effects of a 12-week training program on the anthropometric and physiological profiles of some participants in a fitness center. A total of 86 participants (40 from the experimental group and 46 from the control group) with age ranging from 17 to 53 years were subjected to pre- and posttraining assessments of, anthropometric parameters, physiological parameters, and performance. Anthropometric parameters (weight, height, body mass index [BMI], waist circumference [WC]) and blood pressure (diastolic blood pressure, systolic blood pressure [SBP]) were measured according to standard protocols. Heart rate was recorded using a heart rate monitor. Cardiorespiratory fitness (maximal oxygen uptake or VO2peak) was estimated by the 20-multistage shuttle run test. All the data was collected twice within 12 weeks. Weight, BMI, and WC did not show any significant variation (P>0.05) after a 12-week training program. VO2peak increase was insignificant (P>0.05) higher in men (7.5%, P=0.06), compared to women (5.4%, P=0.4). We noticed a significant reduction (P=0.002) in the SBP of men. Significant increase of HR max was found in women. There was an improvement of 13.7% in the VO2peak of the participants who did not consume alcohol. These results demonstrate the slight benefits of a 12-week training program on health. The weight characteristics of the participants and lifestyle may play an important role in these interactions.
