[Central obesity among Islamshahr women, their perception of obesity, and their husband's views on the subject]

Weight status perception is an important factor in nutritional behavior. The aim of this study was to determine Islamshahr women's self-perception of their obesity status and perception of their husband's opinions regarding women's obesity status, as compared with the actual central obesity status of the women. This was a cross-sectional (descriptive-analytical) study carried out in 2003 on a cluster sample of Islamshahr women aged 20-65 years (n = 704). Data were collected by interviews and weight, height, and waist and hip circumferences were measured. A waist-to-hip ratio (WHR) greater than 0.849 was considered as central obesity. Based on the body mass index [BMI=weight/height2(kg/m2)], underweight, normal, overweight, and obese were defined as a BMI <18.5, 18.5-24.9, 25-29.9, and ≥30, respectively. About 35% of the women with central obesity considered themselves underweight or normal. Married women's perception of husband's opinions regarding their obesity status showed about 45% misclassification. Women with central obesity who thought their husbands would assess them as underweight or normal were more likely [OR=18.6, 95% CI: 9.1 to 38.2] to underestimate their obesity status as well. Misperception of obesity status is common among Islamshahr women. Considering the role of central obesity in metabolic diseases, menstrual disorders and increasing serum androgens, conducting nutrition education programs is essential for prevention and control of central obesity in the region studied.
