RESUMO

The prevalence of undernutrition in hospitals in Africa is estimated at about 57 %. Simple anthropometric methods are available to detect it, including measurement of the brachial circumference (BC) and the body mass index (BMI). The aim of this study was to identify a threshold value that might make it possible to diagnose undernutrition in hospitals. It was a cross sectional study carried out at Douala General Hospital - Cameroon over a five months period. The measurements studied were: BMI, BC and percentage of weight loss. The Pearson test was used to compare the quantitative variables. The Receiving Operating Characteristic curve enabled us to determine a threshold value of the BC according to BMI. The study included 333 patients, with a mean age of 45 ± 16 years (range : 18-86). BMI and BC were strongly correlated; BC =11.69 + 0.68(BMI), with r2 = 0.65 (P < 0.01)). The threshold value of BC retained to detect undernutrition was 27 cm. The prevalence of undernutrition at the Douala General Hospital varies according to the anthropometric parameter used. At a BC threshold of 27 cm, the prevalence of undenutrition in our population was 24,3%.

RESUMO

INTRODUCTION: The causes of gastroduodenal lesions are multifactorial, and few studies have assessed the impact of each of these factors in Africa. The aim of this study was to identify factors associated with the occurrence of gastroduodenal lesions in Cameroon. METHOD: This prospective, analytical study took place over a 5-month period in the endoscopy unit of the Douala General Hospital. Lifestyle, medical history, demographic, and clinical variables were collected. Infection with Helicobacter pylori was determined with a rapid urease (CLO) test. Multivariate regression was used to determine risk factors. RESULTS: The study included 234 of 265 patients seen in the department over the study period. Gastroscopy was normal for 54.2% of the subjects. The prevalence of peptic ulcers was 17.1% and of inflammatory lesions 26.4%. Risk factors associated with a gastroduodenal lesion were: age greater than 60 years [OR age = 2.953; 95% CI: 1.399 to 6.231; p = 0.004], H. pylori infection [OR = 2.953; 95% CI: 1.399 to 6.231; p = 0.003] and regular NSAID use [OR = 0.912; 95% CI: 0.112 to 2.733; p = 0.044] either a month before the examination or over the long term. CONCLUSION: Age greater than 60 years, NSAID consumption, and H. pylori infection are associated with the occurrence of gastroduodenal lesions.
