Effect of Age 40 on Body Composition, Cardiometabolic Risk Factors and Testosterone Levels in First Response Teams

Yıl 2024, Cilt: 7 Sayı: 4, 132 - 145, 31.12.2024

Purpose: The aim of this study is to investigate the effect of the 40-year-old period on body composition, cardiometabolic risk factors and testosterone levels in first response teams. 55 volunteers between the ages of 24-54 who work in first response teams participated in the study. The volunteers participating in the study were divided into two groups in terms of chronological age, those under 40 (G1) and those over (G2).
Method: The age of the participants was determined based on their identity information. Height and body weight were measured to calculate body mass index. Waist and hip circumferences were measured with a cuffed tape measure to determine waist-hip ratio. Body fat ratio (%) was determined by bioelectrical impedance analysis. Systolic and diastolic blood pressure and resting heart rate of the participants were measured. For biochemical analyses, blood samples were taken in the fasting state and analyzed by expert personnel in the laboratory. Fasting blood sugar, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol and triglyceride levels were analyzed to determine testosterone levels and cardiometabolic risk factors.
Results: When the findings were evaluated, it was numerically observed that there was a decrease in testosterone levels, body weight, body mass index, body fat percentage, waist-hip circumference, waist-hip ratio, fasting blood sugar level, total cholesterol, triglyceride, low-density lipoprotein cholesterol levels and a decrease in high-density lipoprotein cholesterol levels in participants over the age of 40.
Conclusion: As a result, it was determined that there was a negative numerical significant relationship between the decrease in testosterone levels and cardiometabolic risk factors.

İlk Müdahale Ekiplerinde 40 Yaş Periyodunun Vücut Kompozisyonu Kardiyometabolik Risk Faktörleri Ve Testosteron Düzeyine Etkisi

Yıl 2024, Cilt: 7 Sayı: 4, 132 - 145, 31.12.2024

Öz

Amaç: Bu çalışmanın amacı ilk müdahale ekiplerinde 40 yaş periyodunun vücut kompozisyonu, kardiyometabolik risk faktörleri ve testosteron düzeyine etkisinin araştırılmasıdır. Çalışmaya 24-54 yaş aralığında olan, ilk müdahale ekiplerinde çalışan 55 gönüllü katılmıştır. Çalışmaya katılan gönüllüler kronolojik yaş olarak, 40 yaş altıda (G1) ve üstünde (G2) olanlar iki gruba ayrılmıştır.
Yöntem: Katılımcıların yaşı kimlik bilgisi esas alınarak belirlenmiştir. Boy uzunluğu ve vücut ağırlığı ölçülerek beden kütle indeksi hesaplanmıştır. Bel ve kalça çevresi kelepçeli mezura ile ölçülerek bel – kalça oranı belirlenmiştir. Vücut yağ oranı (%), biyoelektrik empedans analizi ile belirlenmiştir. Katılımcıların sistolik ve diyastolik kan basıncı ile istirahat kalp atım sayısı ölçülmüştür. Biyokimyasal analizler için, açlık durumunda kan örnekleri alınarak laboratuvarda uzman personel tarafından analizleri gerçekleştirilmiştir. Testosteron düzeyi ile kardiyometabolik risk faktörlerinin belirlenmesi amacıyla açlık kan şekeri, total kolesterol, düşük dansiteli lipoprotein kolesterol, yüksek dansiteli lipoprotein kolesterol ve trigliserit seviyeleri analiz edilmiştir.
Bulgular: Bulgular değerlendirildiğinde, 40 yaş üstü katılımcılarda testosteron düzeyindeki azalma, vücut ağırlığı, beden kütle indeksi, vücut yağ yüzdesi, bel - kalça çevresi, bel - kalça oranı, açlık kan şekeri düzeyi, total kolesterol, trigliserit, düşük dansiteli lipoprotein kolesterol düzeyinde artış ve yüksek dansiteli lipoprotein kolesterol düzeyinde ise azalmanın olduğu numerik olarak görülmektedir.
Sonuç: Sonuç olarak testosteron düzeyindeki azalma ile kardiyometabolik risk faktörleri arasında negatif yönlü sayısal değer olarak anlamlı bir ilişkinin olduğu tespit edilmiştir.
