FREQUENCY OFABNORMALWAIST CIRCUMFERENCE AND ASSOCIATED RISK FACTORS IN HEALTHYADULTS

Abstract

Objective: To find out the frequency of central obesity and risk factors for obesity based on waist

circumference (WC) in healthy volunteers.

Material and Methods: This descriptive cross-sectional study in terms of data collection and analysis

was conducted at Hayatabad Medical Complex (HMC) and Welfare Clinics in Peshawar City, from

November 2005 till April 2006 (6 months). A convenient sample of 1031 healthy volunteers accompanying

their patient to Out Patient Department (OPD), Ward at HMC and at welfare clinics in the city were

included in the study. A structured interview questionnaire was administered to all participants and their

anthropometric measurements taken in standardized way.

Results: Out of 1031 individuals (778 males, 253 females) with mean age of 35.75±13.45 years, the

frequency of high waist circumference was 57%, significantly higher in females (89%) compared to males

(47%). It increased with age peaking at 49-58 year age group and declining thereafter. Married subjects

(67%), illiterates (69%), housewives (96%), car-owners (61%) and hypertensive subjects had significantly

higher frequencies of increased waist circumference. Ethnicity (p=0.45), smoking (p=0.36) and awareness

of risks (p=0.91) did not show significant association with frequency of increased waist.

Conclusion: There is a very high frequency of increased waist circumference particularly among females.

There is progressive increase in waist with increasing age with a decline later in life. There is positive

association of increased waist with occupation, educational status, use of cars and married marital status.

There is no association of high waist with smoking, awareness or ethnicity.
