Abstract

Objective: The aim of this study was to delineate in detail the longitudinal association of total cholesterol (TC) and highdensity lipoprotein cholesterol (HDL-C) levels with overall mortality in middle-aged participants of the biennial Turkish Adult Risk Factor study.Methods: Baseline lipid variables were analyzed in sex-specific deciles. A baseline age of 45 to 84 years as an inclusion criterion led to the enrollment of 2121 men and women. Cox regression analyses were performed.Results: Deaths were recorded in 237 and 306 women and men, respectively, during a mean 8.85±4.4 years of follow-up. After adjustment for age, smoking status, lipid-lowering and antihypertensive drug usage, prevalent diabetes, and coronary heart disease, and using the lowest decile as referent, neither TC (p trend=0.94 and 0.96, respectively), nor HDL-C categories (p trend=0.20 and 0.31, respectively) were significantly predictive of mortality in either gender. TC deciles exhibited a gender difference insofar as hazard ratios in females tended to be reciprocal to those in males in deciles 2 through 5.Conclusion: The findings on TC deciles may be attributed to a comparatively higher death rate in the female (compared with male) bottom decile, reflecting the autoimmune process-induced elevated risk in the lowest decile. Observations on HDLC confirmed presumed pro-inflammatory conversion in levels >50 mg/dL. These results have important clinical implications.L

Özet

Amaç: Total kolesterol (TK) ile yüksek-yoğunluklu lipoprotein kolesterol (HDL-C) düzeylerinin TEKHARF Çalışması'nda kapsanan orta yaşlı katılımcılarda genel mortalite ile öne dönük ilişkisini ayrıntılı biçimde belirlemektir. Yöntemler: Başlangıçtaki lipid değişkenleri cinsiyete özgü ondabir dilimlerde analiz edildi. Başlangıçtaki yaşın 45-84 olarak alınma ölçütü 2121 erkek ile kadının içerilmesine izin verdi. Cox regresyon analizleri uygulandı. Bulgular: Ortalama 8.85±4.4 yıllık izlemede ölüm 237 kadın ile 306 erkekte saptandı. Yaş sigara içiciliği, lipid düşürücü ve antihipertansif ilaç kullanımı, başlangıçta diyabet ve koroner kalp hastalığına ayarlamadan sonra ve en alt ondabir dilim referent olarak alınınca, ne TK (sırasıyla, p trend =0.94 ve 0.96), ne de HDL-C kategorileri (sırasıyla, p trend =0.20 ve 0.31) iki cinsiyette de mortaliteyi anlamlı öngörmedi. TK dilimleri, kadınlardaki hazard oranlarının 2.-5. dilimlerde erkektekilere göre ayna halini sergileme eğilimleri ile ayrıştılar. Sonuç: Total kolesterol ondabir dilimlerine ilişkin bulgular, erkektekine kıyasla, kadında en alt dilimde göreli yüksek ölüm oranına atfedilebilir ki bu da anılan dilimde otoimmün sürecin indüklediği yüksek riski yansıtır. Yüksek-yoğunluklu lipoprotein kolesterole ilişkin gözlemlerimiz >50 mg/dL düzeylerinin yangısal dönüşüme uğradığını desteklemektedir. Bu saptamalar önemli klinik çıkarımlar taşır.
