摘要

Objectives: Obesity, with its rapid increment, had became a major health problem in worldwide and Taiwan. There are limited epidemiological data focusing on the rural female elderly in Taiwan. This study was planed to explore the prevalence of obesity and the association with age and waist circumference in female elderly lived in rural Taiwan.
Methods: A total of 368 ambulatory elderly women (65 year-old or more) randomly sampled from a rural community (Tianliao township) were analyzed. The response rate was 75.9%. Body weight, height and mid-way waist circumference (WC) were measured in a standard way by a well trained staff. Questionnaires including the demographic data and biopsychosocial characteristics were interviewed by staff. According to the recommendations of Asia Pacific Obesity Association in 2000, subjects were categorized into either non-obese (BMI＜ 25 kg/m^2) or obese group (BMI ≧25 kg/m^2) by four age groups ( 65-69, 70-74, 75-79 and ≧80 years-old) for further study.
Results: The mean age of study subjects was 74.4±6.0 years-old, BMI was 24.9±3.9 kg/m^2 and WC was 87.5±10.6cm. The prevalence of obesity in total population and four age groups was 46.7%, 64.4%, 43.4%, 41.5% and 32.8%, accordingly. The prevalence of central obesity (WC≧80cm) in total population was 76.4%. The mean WC in four age groups was 89.3±9.1cm, 87.0±11.3cm, 88.4±10.4cm and 84.6±11.1cm, respectively. The decrement of obesity and waist circumference along with four age groups were found [p＜0.05 and p=0.001, respectively]. Using multiple logistic regression analysis, the age and waist circumference were significant independent factors for obesity. The hypertension history, diabetes history, marital status, and habit of tea drinking were not associated with the prevalence of obesity in the rural Taiwan.
Conclusion: In rural Taiwan, the high prevalence of obesity was found in female elderly. The age and waist circumference were the independently associated with obesity. The changing pattern of body size favoring decrement of obesity and waist circumference along with age was clearly demonstrated in female elderly lived in rural community of southern Taiwan.
