The effects of physical exercises combined with a low-calorie diet on weight loss, body composition, lipoproteins profile, and physical fitness had been well described. However, Central Africa’s studies investigating these kinds of diets and exercise regimens are lacking. Objective. To investigate the effects of adding 14-weeks exercises to a hypocaloric diet on changes in body composition, lipoproteins concentrations, and physical capacities in obese Congolese women. Population and Methods. In total, 34 obese women aged 30 - 39 years (mean age: 33.7 ± 2.4 years) assigned to 14-weeks training program and low energy ketogenic diet. Body composition was assessed using classic methods and impedancemetry. Fasting plasma glucose (FPG) and fasting serum insulin were assessing using enzymatic colorimetric and radioim-munoradiometric methods. HOMA-IR and lipoproteins concentrations were assessed using standardized laboratory methods. VO2peak was measured on a treadmill during a progressive exercise test. Speed, cadence and stride length were measured along the 10-m level walkway. Muscular endurance was measured using the tests of sit-up and inflections-extensions of elbows. All the variables of the study were assessed at the beginning, in the 7-weeks, and in the 14-weeks of training methods. Results. Declines in body weight (16%), percent fat (12.1%), fat weight (26.4%), abdominal fat (34.2%), and waist circumference (10.4%) were found. A significant decrease in FPG (13%), fasting serum insulin (60.9%), HOMA-IR (64.7%), total cholesterol (12.2%), LDL-cholesterol (20.3%), triglycerides (92.8%), and VLDL-triglycerides (17.5%) was shown. In contrast, significant increase in HDL-cholesterol (27.13%) was found. The peak oxygen consumption VO2peak relative to body weight improved more in the 14-weeks training program (13.4%). Obese women exhibited higher values in the 14-weeks training program for speed gait (16.5%), cadence (9.1%), and stride length (15.7%) during normal walk and rapid walk. Weight loss combined with a low-calorie diet and 14-weeks training program improved significantly muscular endurance capacities. Conclusion. Exercise added to hypocaloric diet leads to decreases in body composition, to improve in insulin sensitivity, to enhancement of VO2peak and functional fitness. This may be helpful for the treatment of the metabolic complications of abdominal obesity.展开更多

Population and Methods: Analytical KAP study, conducted from February 1 to May 31, 2019, including exclusively manner mothers who have started breastfeeding for at least 4 months and at most 24 months in accordance with the recommendations of the World Health Organization. The study variables were related to socio-demographic characteristics, knowledge, attitudes and practices. Results: One hundred and forty mothers were questioned. They were of a median age of 30, multiparous (61.5%), in a couple (78.6%), with gainful activity (47.9%). They had enough knowledge (87.1%) but harmful in 26.5% of cases, adapted attitudes (95%) with answers of different certainties, and bad practices (60%). Knowledge did not influence attitudes (p > 0.2). Knowledge and attitudes influenced practices (p Conclusion: An educational strategy on mothers’ knowledge and attitudes towards breastfeeding would help improve their breastfeeding practices.展开更多
