Middle-aged women's awareness of cholesterol as a risk factor: Results from a national survey of Korean Middle-aged Women's Health Awareness (KomWHA) study

BackgroundDyslipidemia, a risk factor for cardiovascular disease (CVD), is more prevalent in middle-aged women than in men of the same age in Korea. This study, the first national survey that focused on cholesterol in Korean women, aimed to: (1) assess their awareness and knowledge of cholesterol, (2) evaluate their risk reduction behavior, and (3) examine differences in these variables among geographical regions in Korea.MethodsA questionnaire survey study was conducted in a randomly selected national sample of 1304 Korean women, aged 40–64 years in 3 geographic regions.ResultsHigh cholesterol was identified as a cause of CVD by 54.4% of respondents, however, 95.4% did not know their own values. Only 4.1% of respondents were aware of desirable level of total cholesterol. Eight percent of respondents perceived correctly the meaning of high-density lipoprotein cholesterol (HDL-C) as good cholesterol. And 32.9% had cholesterol check at least once a year. No significant regional differences were found in women's awareness and knowledge on cholesterol. No smoking (93.6%), low salt diet (52.5%) and weight management (50.6%) were the most prevalent risk reduction behaviors. Women in the rural area performed less risk reduction behaviors than those in urban area.ConclusionsGiven the low level of awareness and knowledge about cholesterol in these women, nurses need to increase their education about cholesterol and risk reduction behaviors of CVD for middle-aged Korean women, particularly those in rural area. To resolve identified disparities in women's risk reduction behaviors between the rural and urban area, a national-level health policy can result in a successful effort to promote women's awareness of cholesterol and risk reduction behaviors for the cardiovascular health of the public.
