Leptin is an adipokine playing a key role in energy balance and metabolic processes, and its serum levels are significantly increased in obesity. The hypothesis that increased leptin levels may negatively affect cardiovascular risk factors by contributing to dyslipidemia was investigated.Methods: PubMed, Scopus, and Web of Science databases were searched for studies published between January 2010 and October 2023. Eighteen studies meeting the inclusion criteria were analyzed. Data were collected to assess the associations between leptin levels and lipid profile parameters (total cholesterol, LDL-cholesterol, HDL-cholesterol, triglycerides) and cardiovascular risk factors, such as markers of inflammation, blood pressure (BP), and insulin resistance (IR). Results: Positive and statistically significant associations were found between leptin levels and total cholesterol (r=0.45, p KW - Leptin KW - Obesity KW - Lipid Profile KW - Cardiovascular Disease KW - Dislipidemia KW - Insülin Resistance KW - inflammation N2 - Amaç: Bu çalışma, obez bireylerde leptin hormonunun lipid profili ve kardiyovasküler hastalık risk faktörleri üzerindeki etkilerini değerlendirmek amacıyla sistematik bir literatür taraması olarak gerçekleştirilmiştir. Leptin, enerji dengesi ve metabolik süreçlerde önemli rol oynayan bir adipokindir ve obezite durumunda serum seviyeleri belirgin şekilde artar. Artan leptin düzeylerinin dislipidemiye katkıda bulunarak kardiyovasküler risk faktörlerini olumsuz etkileyebileceği hipotezi araştırılmıştır.Gereç ve Yöntemler: Ocak 2010 ile Ekim 2023 tarihleri arasında PubMed, Scopus ve Web of Science veri tabanlarında yayınlanmış çalışmalar taranmıştır. Dahil edilme kriterlerini karşılayan 18 çalışma analiz edilmiştir. Leptin düzeyleri ile lipid profili parametreleri (toplam kolesterol, LDL-kolesterol, HDL-kolesterol, trigliseritler) ve kardiyovasküler risk faktörleri (inflamasyon belirteçleri, kan basıncı, insülin direnci) arasındaki ilişkiler değerlendirilmiştir.Bulgular: Leptin düzeyleri ile toplam kolesterol (r=0.45, p CR - 1.
