Aim: The association between neck circumference (NC) and cardiometabolic risk factors in Southwest Nigeria is unknown. The study aimed at determining the relationship between NC and cardiometabolic risk factors. 

Methods: Result of a cross-sectional health survey involving residents of Ado-Ekiti/Ika community in Ekiti State was analyzed. Clinical measurements of body mass index (BMI), waist circumference (WC), waist-to-height ratio (WHtR), neck circumference, systolic/diastolic blood pressures (SBP & DBP) were taken, and random blood glucose (RBG) determined. Bivariate correlations and linear regression models were computed for each sex. 

Results: There were 211 participants out of which 78 (37.0%) were men. Among men, NC was significantly correlated with weight (r=0.412, p<0.001) and BMI (r=0.362, p<0.01). Among women, NC correlated with weight (r=0.319, p<0.001), BMI (r=0.228, p<0.01), WC (r=0.238, p<0.01), SBP (r=0.444, p<0.001), DBP (r=0.423, p<0.05), and RBG (r=0.203, p<0.05). NC independently predicted SBP, ORs (95%CI), 2.707 (1.468-3.946) and DBP, ORs (95%CI), 1.780 (0.950-2.611) in women, but not in men. While only the NC of men with general obesity was greater than those who do not have, 39.27(5.68)cm vs 36.96(3.46)cm, p=0.04, the NC of women who were obese or had hypertension were significantly greater than those who were not: general obesity, 33.17(2.58)cm vs 31.57(3.08cm), p=0.002; central obesity, 32.88(2.99)cm vs 31.09(2.62)cm, p<0.001; hypertension, 34.39(2.77)cm vs 31.88(2.88)cm, p=0.001). Compared with those in the upper tertile, men with NC in the middle tertile had lower mean weight [60.82 (8.67) kg vs 68.90 (10.08) kg, p=0.005], BMI [21.31 (2.54) kgm2 vs 23.72 (3.77) kgm2, p=0.022], WC [78.32 (5.57) cm vs 85.14 (8.72), p=0.003], and WHtR [0.464 (0.06) vs 0.50 (0.06), p=0.004].Compared with those in the upper tertile, women with NC in the lower tertile had lower mean weight [56.81(9.80) kg vs 66.08(13.50)kg, p=0.031], SBP [107.53 (15.59) mmHg vs 132.38 (15.85) mmHg, p<0.001], and DBP [69.27 (10.91) mmHg vs 84.69 (10.52) mmHg, p<0.001].

Conclusions: Neck circumference has positive association with, and predicts cardiometabolic risk factors, and may serve as an index of obesity in Ekiti, Nigeria.

Nijerya'da Ekiti'de boyun çevresi ve kardiyo-metabolik risk faktörlerinin pozitif ilişkisi

Amaç: Güneybatı Nijerya'da boyun çevresi (NC) ve kardiyometabolik risk faktörleri arasındaki ilişki bilinmemektedir. Çalışma, NC ve kardiyometabolik risk faktörleri arasındaki ilişkiyi belirlemeyi amaçlamıştır.

Yöntemler: Ekiti Devletinde Ado-Ekiti / Ika topluluğu sakinlerini içeren kesitsel bir sağlık araştırması sonuçları analiz edildi. Vücut kitle indeksi (BMI), bel çevresi (WC), bel-boy oranı (WHtR), boyun çevresi, sistolik / diyastolik kan basınçları (SBP ve DBP) klinik ölçümleri alındı ve rastgele kan şekeri (RBG) belirlendi. Her cinsiyet için iki değişkenli korelasyonlar ve doğrusal regresyon modelleri hesaplandı.

Bulgular: 78'i (%37,0) erkek olan 211 katılımcı vardı. Erkekler arasında NC, ağırlıkla (r=0,412, p<0,001) ve BMI (r=0.362, p<0,01) ile anlamlı olarak koreleydi. Erkeklerde olmamakla birlikte kadınlar arasında NC (r=0,319, p<0,001), BMI (r=0,228, p<0,01), WC (r=0,238, p<0,01), SBP (r=0,444, p<0,001) ile korele bulundu. DBP (r=0,423, p<0,05) ve RBG (r=0,203, p<0,05). NC bağımsız olarak, kadınlarda SBP, OR (%95 CI), 2,707 (1,468-3,946) ve DBP, OR (%95 CI), 1,780 (0,950-2,611). Genel obezitesi olan erkeklerin sadece NC'si olmayanlardan 39,27 (5,68) cm'ye karşılık 36,96 (3,46) cm, p=0.04 iken, obez olan veya hipertansiyonu olan kadınların NC'si, değil: genel obezite, 33,17 (2,58) cm vs 31,57 (3,08 cm), p=0.002; santral obezite, 32,88 (2,99) cm'ye karşı 31,09 (2,62) cm, p<0.001; hipertansiyon, 34,39 (2,77) cm'ye karşı 31,88 (2,88) cm, p = 0.001) idi. Üst tersiyer ile karşılaştırıldığında, orta hüviyette NC olan erkeklerin oranı daha düşüktü [60,82 (8,67) kg / 68,90 (10,08) kg, p=0,005], BMI [21,31 (2,54) kg/m2 ve 23,72 (3,77) kg/m2 idi. , p=0,022], WC [78,32 (5,57) cm'ye karşı 85,14 (8,72), p=0,003] ve WHtR [0,464 (0,06) / 0,50 (0,06), p=0,004]. Üst tersiyerde bulunanlarla karşılaştırıldı, alt kadranda KKY'li kadınlar daha düşük ortalama ağırlığa sahipti [56,81 (9,80) kg / 66,08 (13,50) kg, p=0,031], SBP [107,53 (15,59) mmHg ve 132,38 (15,85) mmHg, p=0,000] ve DBP [69,27 (10,91) mmHg, 84,69 (10,52) mmHg, p=0,000].

Sonuçlar: Boyun çevresi kardiyometabolik risk faktörleri ile pozitif ilişkilidir ve tahmin eder ve Nijerya'daki Ekiti'de bir obezite endeksi olarak hizmet edebilir.
