Diabetes mellitus, a chronic disease, significantly impairs quality of life. In Chad, data on this subject are scarce. This study evaluates the quality of life of diabetic patients followed at the National Reference University Hospital of N'Djamena, using the ADDQOL questionnaire. To assess the QoL of diabetics and identify the factors that can influence it. A cross-sectional and analytical study was conducted with 130 diabetic patients (types 1 and 2) during consultations. The ADDQOL questionnaire was used to assess the impact of diabetes on several aspects of life. A weighted score (impact × importance) was calculated and analyzed. In total, we collected data on 130 diabetic patients. The mean age of the patients was 40.93 ± 12.3 years, with a range from 36 to 65 years. Males were predominant, with a male-to-female ratio of 1.2. The overall weighted score was -2.56, indicating moderate to severe impairment. The most affected areas were: dietary freedom (-4.57), drinking (-4.18), finances (-3.67), work (-3.63), and sexuality (-3.13). Other aspects, such as physical appearance and self-confidence, were also affected. Unlike other variables significantly associated with impaired quality of life—low socioeconomic status, diabetes duration ≥ 5 years, insulin therapy, oral antidiabetic drug use, diabetic foot, hypoglycemia, acidosis, and type 1 diabetes—type 2 diabetes did not show a statistically significant association in our analysis (OR = 2.13; 95% CI: 0.76–5.93; p = 0.138). Diabetes affects various aspects of life, including independence, social life, and intimate relationships. These findings highlight the need to integrate quality of life assessment into patient care, along with appropriate psychological, nutritional, and social support.
