Marka loo eego daraasad dhowaan lagu daabacay JAMA Oncology, buurnaanta ayaa la xiriirta khatarta sii kordheysa ee kansarka mindhicirka hore ee haweenka (CRC).
Dhakhtar caafimaad oo ka socda isbitaalka guud ee Boston Massachusetts ayaa sameeyay daraasad si loo ogaado waxa ku dhaca kansarka malawadka ee ku dhaca dumarka 85,256 ee aan lahayn kansarka iyo cudurada caloosha ee caabuqa ku saleysan xogta laga soo qaado haweenka 25-sano jirka ah.
Cilmi-baadhayaashu waxay heleen 114 kiis oo bilawgii hore ee CRC (da'da dhexe ee cudurka, 45 sano) inta lagu jiro muddada daraasadda. Dumarka cayilan (BMI, 25-29.9 kg / m²) iyo haweenka buuran (BMI, ≥30 kg / m²) oo leh miisaan caadi ah (BMI waa 18.5-22.9 kg / m²) marka la barbardhigo haweenka, CRC waxay kordhisay khatarta. Helitaankan waxa loo nisbayn karaa BMI marka ay 18 jir tahay iyo korodhka miisaanka ka dib 18 sano jir. 5-tii unug kasta ee BMI korodhka , RR (khatarta qaraabo) ee kansarka mindhicirka waxay kordhisaa 1.2 . Marka la barbardhigo 18 jir BMI waxay ahayd 18.5-20.9 kg m² / dhedig, BMI waa 21 - 22.9 kg / m² dumarka, bilawgii hore ee CRC ee RRIs 1.32, BMI waa ≥23kg dheddigga RR waxay ahayd 1.63. Sidoo kale, marka la barbardhigo dumarka helay wax ka yar 5 kg ama miisaankoodu hoos u dhacay, haweenku waxay lahaayeen koror ah 20-39.9 kg bilawgii hore ee CRC iyada oo RR ah 1.65, haweenku waxay kordheen ≥40 kg iyo RR 2.15.
