Prevalence and correlates of self-reported disordered eating: A cross-sectional study among 90 592 middle-aged Norwegian women
Disordered eating (DE) is extensively studied among adolescents and young women. However, there is growing evidence that DE as well as the clinical eating disorders may occur at any age from childhood to advanced years. This study aimed to determine the prevalence and correlates of DE in a representative sample of middle-aged women from Norway. The study included 90 592 women (median age: 55 years) from the Norwegian Women and Cancer study who responded to a questionnaire between the years 2002–2005. Correlates of self-reported DE were assessed by logistic regression analyses. The overall period prevalence of DE between 2002–2005 was 0.28 (95% confidence interval 0.25–0.31) %, and was highest among women ≥ 66 years: 0.65 (0.60–0.70) %. DE was strongly associated with depression (Odds ratio [OR] 3.34 [95% confidence interval 2.53–4.41]), being unemployed (OR 1.78 [1.32–2.40]) and single (OR 1.66 [1.25–2.20]). Women with DE were more likely to report low energy intake (OR 1.41 [1.08–1.86]) and were less likely to be moderately physically active (OR 0.67 [0.47–0.95]). Using the largest study sample in the literature, the present findings confirm smaller studies showing that DE do occur in women in mid-life and older age as well. Our results contribute to address a somewhat under-communicated community health problem that needs attention in terms of age-specific treatment and prevention.
