Abstract: Objective To explore perimenopausal women's dietary structure,the prevalence of menopause syndrome and its related factors.Methods Totally 862 female outpatients from 3 hospitals were selected.The patients were aged between 40 and 60 years,with uterus and one or two ovaries,and with menstrual changes or menopause syndrome symptoms.The menopausal symptoms were graded by improved Kupperman evaluation standard and the diet structure was evaluated with the standard of "The China Dietary Guidelines(2007)".Results The menarche age of the perimenopausal women was 14.8±1.9 years and the menostasis age was 49.2±4.8 years.There were 799(92.69%)patients having one or more menopause symptoms.Linear correlation analyses showed that improved Kupperman symptom score was correlated with menopause syndrome score.The dietary structure of the patients was not consistent with the recommended value of the Chinese balanced diet guide.Conclusion Most of the perimenopausal women's dietary structure was not rational.The relationship between dietary behavior and menopausal symptoms needs further research.
