title: Blood pressure and waist circumference: an empirical study of the effects of waist circumference on blood pressure among Bengalee male jute mill workers of Belur, West Bengal, India.
abstract: An investigation of 150 adult Bengalee Hindu male jute mill workers in Belur, a suburb of Kolkata, West Bengal, India, was conducted to study the relationship between central obesity and blood pressure. In accordance with their waist circumference measurement, the subjects were divided into two categories: centrally non-obese (CNO) and centrally obese (CO). The participants were classified as the CO group if they had a WC of 80 cm or more. Results showed that none of the CNO subjects was mild hypertensive (SBP>/=140 mmHg and/or DBP>/=90 mmHg) while 85 of the CO subjects (82.5%) were mild hypertensives, the difference being statistically significant (chi-square=9.33; p<0.0025). Moreover, the data also revealed that the CO subjects had much (p<0.001) greater mean weight, body mass index (BMI), systolic (SBP), diastolic (DBP) and mean arterial (MAP) blood pressure than the CNO group members. The significant difference in blood pressure was found even after correcting the confounding effects of age and BMI variables. The results of this study showed that, the Bengalee male jute mill workers in the CO group had significantly higher blood pressure irrespective of age and overall adiposity (BMI). Therefore, the presence of central obesity is deemed a risk factor, for hypertension regardless of age and BMI. Thus, a WC cut-off point of 80 cm could be employed for health promotion among Bengalee men so as to prevent and manage hypertension effectively.
