The general objective of this study is to carry out a qualitative and quantitative analysis of the garbage from the commune of BOLIKANGO in the city of Lisala, Province of Mongala and to test the adequacy of the methods of storage and elimination of this waste. To achieve this, we used the descriptive method for waste identification using living techniques such as direct or indirect observation and structured sowing interviews. Results obtained revealed the following points: Awareness of the problem by the inhabitants of the commune of BOLIKANGO. 80% of the population surveyed recognizes that the waste problem exists and that biodegradable organic matter is the main source of garbage in households. In addition to organic matter, waste made up of metals, such as sardine cans, tomatoes, spare parts for vehicles and motorcycles, cells and batteries come second. These methods enabled us to note that the solid waste produced in the commune of BOLIKANGO is badly managed with enormous risks for the health of the population, of the households all around the commune concerned.The inhabitants of the district have neither trash, nor dump at the level of their installations throw their waste directly on the ground and without service of daily collection, the inhabitants themselves take care of the sweeping and the evacuation of waste. It emerges from this study that:Garbage exists and includes a mixture of constituents, the main ones being plant waste, animal waste, waste from manufacturing products, construction accessories and human waste.The largest single quantity of garbage is produced at the central market in Lisala, i.e. 90000m3.The state service for collecting, sorting and eliminating waste in the municipality is not operational. You can see the hills of waste abandoned in some markets and others throw their waste squarely into rivers.We say that at the level of the municipality, that is to say the real ecological problems exist and because of an unhealthy environment, several contagious and infectious diseases circulate in the population because the application of the law remains not applicable everywhere in the DRC.

Low birth weight is defined by the World Health Organization (WHO) as a birth weight strictly less than 2500g, regardless of the term of the pregnancy. It constitutes a major public health problem, in both developed and developing countries, by virtue of its magnitude and its strong association with infant morbidity and mortality.Our cross-sectional descriptive study analyzes the characteristics of mothers and their newborns. The target of this study consisted of all newborn babies living during the period from January to December 2019, of single fetal pregnancy.At the end of our study, we reported 242 newborns with low birth weight out of 1998 live births, ie 12.1% grouped together in low weight; very low weight and extremely very low weight.During our study, we noted that parturients who had not reached the 4 CPN were approximately 7 times more likely to have birth weights ˂1500g and this difference was statistically significant. OR = 7.60 (95% CI 1.01-57.31) Chi2 = 4.1 p = 0.04.On the socio-demographic level, 31.8% of parturients came from the Municipality of Kampemba; 83.1% were married; 37.2% were primiparous; 55.37% of NNEs were Female; Malaria predominated at 38.4% followed by urinary tract infections 17.4%; HIV infection: 1.7%.This work could help health care workers at all levels of the system to better understand the problems of low birth weight and to do more for the health of mothers and children.
