Association of obesity anthropometric indices with hypertension, diabetes mellitus and hypertriglyceridemia in apparently healthy adult Nigerian population

Table 1 Number of risk subjects and percentage risk for study parameters

Risk cut-off of parameter	Number of subjects	Percentage risk
SBP ≥ 140 mmHg	36/221	16.3
DBP ≥ 90 mmHg	22/221	10.0
FBG ≥ 7.0 mmol/L	06/221	2.7
TG ≥ 1.7 mmol/L	42/221	19.0
BMI ≥ 30.0 kg/m2	62/221	28.1

SBP: Systolic blood pressures; DBP: Diastolic blood pressures; FBG: Fasting blood glucose; BMI: Body mass index; TG: Triglycerides.

Table 2 The order of correlation of the anthropometric indices with risk parameters

Risk-parameter	Order of correlation with anthropometric indices, highest (1) to lowest (6)
	1	2	3	4	5	6
SBP	AH	WC	WHR	BSI	WHtR	BMI
DBP	AH	WC	BSI	WHtR	BMI	WHR
FBG	AH	WC	WHtR	WHR	BSI	BMI
Triglycerides	AH	BSI	WC	BMI	WHtR	WHR

AH: Abdominal height; SBP: Systolic blood pressures; DBP: Diastolic blood pressures; FBG: Fasting blood glucose; BMI: Body mass index; WC: Waist circumference; WHtR: Waist-to-height ratio; WHR: Waist-to-hip ratio; BSI: Body surface index.

Table 3 Correlation between abdominal height and other anthropometric indices

	WC	BMI	WHtR	WHR	BSI
AH	0.944	0.872	0.905	0.682	0.892
P value	0.000	0.000	0.000	0.000	0.000

AH: Abdominal height; BMI: Body mass index; WC: Waist circumference; WHtR: Waist-to-height ratio; WHR: Waist-to-hip ratio; BSI: Body surface index.

Table 4 Receiver operating characteristic curve analysis with cut-off values of abdominal height for risk parameters

Disease condition	Risk value	AH cut-off (cm)	Sensitivity, %	Specificity, %	AUC	95%CI
Hypertension (SBP)	≥ 140 mmHg	24.75	66.7	56.8	0.638	0.544-0.730
Hypertension (DBP)	≥ 90 mmHg	24.75	77.3	56.3	0.664	0.551-0.778
Hyperglycemia (FBG)	≥ 7.0 mmol/L	25.25	66.7	58.6	0.621	0.344-0.899
Hypertriglyceridemia (TG)	≥ 1.7 mmol/L	24.75	83.3	61.5	0.751	0.675-0.827
Obesity (BMI)	≥ 30.0 kg/m2	25.75	85.5	79.2	0.923	0.889-0.957

AH: Abdominal height; TG: Triglycerides; BMI: Body mass index; SBP: Systolic blood pressures; DBP: Diastolic blood pressures; FBG: Fasting blood glucose; AUC: Area under the curve; CI: Confidence interval.
