Association between prevalence of anaemia and sedentary time among women

Abstract

This study aimed to assess the associations between prevalence of anaemia and sedentary time among women. Data of women aged ≥ 10 y who were included in the 6 th Korea National Health and Nutrition Examination Survey (2014-2015) were analyzed (n=3, 593). Self-reported sedentary time was dichotomized into ≥ 7.5 h/d or <7.5 h/d. Sampling weights were generated based on the complex sample to ensure the representativeness of the sample to the Korean population. Logistic regression was used to identify the associations between prevalence of anaemia and sedentary time. The prevalence of anaemia among women aged ≥ 10 y was 9.8%. After adjusting for age, results showed that women with a prevalence of anaemia had a 31% lower odds of sitting for ≥ 7.5 h/d (odds ratios (OR), 0.69; 95% confidence interval (CI), 0.52-0.91) than those without prevalence of anaemia. Women aged between 10-14 y were 7.19 times (CI, 4.28-12.14) more likely to sit for ≥ 7.5 h/d than those aged over 50 y. These findings imply that anaemia control in women aged 10-14 y is necessary to reduce excessive sedentary time.
