This paper is a systematic literature review following PRISMA guidelines that evaluated evidence from original studies published within the past 15 years on associations between smoking, physical activity, and nutrition with endometriosis development and progression. From over 3,500 records, 30 studies were included, totaling data from 949,803 women, and the review found that nutrition was examined in 17 studies, physical activity in 8, and smoking in 5. Across the included studies, the authors report results consistent with the idea that healthier lifestyle patterns may be associated with lower risk of endometriosis onset and/or less severe symptoms, while noting methodological limitations. This paper is centrally about endometriosis — it synthesizes evidence linking modifiable behaviors (smoking, physical activity, and diet) to endometriosis development and symptom severity.

Abstract

Aim of the study. To evaluate scientific literature data on the associations of smoking, physical activity, and diet with the development and progression of endometriosis, as well as the potential for disease prevention and management, considering modifiable behavioural factors. Methods. A systematic literature review was conducted in accordance with PRISMA guidelines. Scientific publications were retrieved from major international databases using targeted keywords related to smoking, physical activity, and diet. Inclusion criteria encompassed original studies published within the last 15 years. Of more than 3500 identified records, 30 studies meeting predefined eligibility criteria were included in the final analysis. Results. The selected studies included data from 949,803 women. The types of studies were as follows: 11 cross-sectional, 8 cohort, 6 case-control, 4 interventional, and 1 retrospective case series. Dietary factors were examined in 17 studies, physical activity in 8, and smoking in 5. Findings suggest a possible association between healthier lifestyle patterns and reduced risk or severity of endometriosis; however, further high-quality research is required. Conclusions. Modifiable lifestyle factors may play a supportive role in the prevention and comprehensive management of endometriosis.

Endometriozės vystymosi ir progresavimo sąsajos su rūkymu, fiziniu aktyvumu ir mityba: literatūros apžvalga Santrauka Tyrimo tikslas. Įvertinti mokslinės literatūros duomenis apie rūkymo, fizinio aktyvumo ir mitybos sąsajas su endometriozės atsiradimu ir progresavimu bei aptarti ligos prevencijos ir valdymo galimybes, atsižvelgiant į koreguojamus elgsenos veiksnius. Metodika. Atlikta sisteminė mokslinės literatūros apžvalga, vadovaujantis PRISMA gairėmis. Duomenų paieška vykdyta pagrindinėse tarptautinėse duomenų bazėse, vartojant tikslinius reikšminius žodžius, susijusius su rūkymu, fiziniu aktyvumu ir mityba. Į analizę įtraukti originalūs tyrimai, publikuoti per pastaruosius 15 metų, atitinkantys iš anksto nustatytus įtraukimo ir atmetimo kriterijus. Iš daugiau nei 3 500 identifikuotų įrašų galutinei analizei atrinkta 30 tyrimų. Rezultatai. Analizuotuose tyrimuose vertinti 949 803 moterų duomenys. Tyrimų tipai: skerspjūvio – 11, kohortiniai – 8, atvejo-kontrolės – 6, intervenciniai – 4, retrospektyvioji atvejo analizė – 1. Mityba nagrinėta 17 tyrimų, fizinis aktyvumas – 8, rūkymas – 5. Gauti rezultatai leidžia daryti prielaidą, kad sveikesni gyvensenos modeliai gali būti susiję su mažesne endometriozės atsiradimo rizika arba jos simptomų sunkumu. Vis dėlto, atsižvelgiant į esamus metodologinius apribojimus, būtini papildomi aukštos kokybės tyrimai. Išvados. Modifikuojami gyvensenos veiksniai gali turėti reikšmingos įtakos endometriozės prevencijai ir integruotam ligos valdymui.
